Chapter 452: Magical Plants in History!

For Zhao Xing's second stage of treatment, the Boundary Transmission Tower was a key location.

Bowei believed that the Desolate Domain era did not have very good means to completely clear the True Spirit Heavenly Poison.

But there were indeed many means in history that could do it.

Especially some plants that had gone extinct in the Desolate Domain era, and the medicinal materials in the ancient prescriptions could not be found at all now.

Similar examples included many natural treasure lands that had disappeared as the Desolate Domain spread.

The Star-Moon Spring, which was once located in the Blue Desolate Domain, dried up 3 epochs before the Desolate Domain. The spring water condensed inside was originally a holy medicine for healing.

Since the end of the Five Emperors era, the Medicine King Realm, which had rapidly declined, once possessed brilliant medical means.

And the divine objects that had lost their divinity at present...

"The Desolate Domain era does not have it,"

"However, there are many means to treat me in the history before the Desolate Domain era." Zhao Xing looked at the list.

"Envoy Ji, in the Heavenly Master Mansion, have you ever heard of the Boundary Transmission Tower?"

Ji Si was pushing Zhao Xing's Flower Chair. Hearing the question, he nodded immediately:

"I have heard of it. The Boundary Transmission Tower is a history-series divine object, containing two Great Daos of time-space and causality. By going to the historical period through the Boundary Transmission Tower, one can even bring treasures back."

Zhao Xing asked curiously: "Does this exist as a paradox? Suppose I take away a divine object from 4 epochs before the Desolate Domain, such as the Great Evolution Divine Weapon of the Red Star Empire. Wouldn't the empire not have the Great Evolution Divine Weapon from 4 epochs before the Desolate Domain to now?"

Ji Si smiled: "Does the Great Agrarian Officer want to ask whether history will change because of this?"

Zhao Xing nodded: "Yes, you practice both the Destiny Official and Historian Great Daos. I want to ask how you view it."

Ji Si pondered: "I have read the classics of the Heavenly Master Mansion. From my understanding, the time-space travel of the Boundary Transmission Tower needs to be discussed in many situations."

"One is real replacement. We can bring back treasures from history. This point proves that we really arrived at the time and space in history through the Boundary Transmission Tower."

"But it will not let us appear at certain key historical nodes, such as going back to the past to kill the juvenile form of a certain Divine Realm expert... This is impossible."

"I said just now that the Boundary Transmission Tower is a divine object containing two Great Daos of time-space and causality."

"Since it is a divine object, its power has an upper limit, and the Boundary Transmission Tower cannot do things that exceed its power."

"Furthermore, the 'bring back' function of the Boundary Transmission Tower follows the principle of equivalent exchange."

"That is, if I bring back a boundary star Daoist weapon or a Reincarnation Daoist weapon from history, I must prepare a Daoist weapon of the same rank for replacement."

"Keep the 【Critical Value】 between the present and the past unchanged."

Zhao Xing thought thoughtfully: "Is the boundary value similar to the spiritual energy value? Does the total amount of spiritual energy in the past and present remain unchanged?"

"It's no problem to say so." Ji Si nodded. "The critical value is the evaluation value of the Boundary Transmission Tower itself, but it is not a simple spiritual energy replacement."

"I don't know the specifics either. The Heavenly Master Mansion has no detailed records."

Following the first situation, Zhao Xing asked the second doubt: "Even if spiritual energy and matter remain balanced, information is ethereal."

"We go back to the past through the Boundary Transmission Tower, and we will also cause influence, right? For example, telling the human race the result of a certain battle, changing the past."

Ji Si replied: "This involves the second situation, the one-way Great Dao isolation of the Boundary Transmission Tower."

"We can get information from the past, but our information cannot truly fall on the historical time and space."

"For example, I went back to the past and wrote a cultivation method for the predecessors, but I couldn't leave this cultivation method in the past."

"Because the cultivation method is the embodiment of the Dao, and my Dao will inevitably not exceed the time-space and causal Great Daos contained in the Boundary Transmission Tower itself. So I cannot cross the barrier of this layer of Dao."

"Conversely, I learned a lost cultivation method from the past. I can bring this cultivation method back."

"I obtained this cultivation method, and it will not cause any influence on the past."

Zhao Xing was puzzled: "Is the replacement of the Boundary Transmission Tower so precise? Some of the ancient medicines I went to pick are extinct. Is this also no problem?"

Ji Che pondered: "The causality and time-space Great Daos contained in the Boundary Transmission Tower itself should bear the cost and smooth out the historical errors."

"Theoretically speaking, the treatment plan Bowei set for the Great Agrarian Officer is feasible."

Ji Si's answer was not very confident either. After all, he was not a god and had never controlled the Boundary Transmission Tower.

Zhao Xing felt that the Boundary Transmission Tower couldn't be so perfect. Even if it were a powerful divine object, it wouldn't be too powerful and too perfect.

If it were really so easy to use, why didn't the ancestors of the Scholar City pass it down, but hid it deep in the Eighth Dharma Realm?

However, there was no answer from Ji Si now. Perhaps Bowei couldn't answer it either.

The trip to the Boundary Transmission Tower had been decided. No matter what, this place was the only way to recover now, and even the treatment fee had already been paid.

There was a lot of preparation work to be done before setting off, and that was to read history thoroughly.

Although Ji Si would accompany him on this trip, Zhao Xing's philosophy had always been that relying on others is not as good as relying on himself.

He was also reading a lot of historical materials.

As a historian, the professional magic he practiced mainly was 【Annals】, 【Ancient Clans】, and 【Biographies】. These were all related to historical figures, mainly reflected in combat power.

As for 【Ten Tables】, it recorded the major events of the Xuanling Star Domain and the contemplation of the Time Great Dao.

Historians who mainly practice 【Eight Books】 have the lowest status because they have no combat power.

The Eight Books mainly record Dao Rituals, Music, Temperament, Star Calendar, Astronomy, and Sealing Talks.

Zhao Xing mainly looked at books related to 【Ten Tables】 and 【Eight Books】, memorizing the major changes in heavenly timing and geographical environment in history, as well as the changes in the territory of the Xuanling Star Domain, and then some miscellaneous talks.

"Clatter~" Zhao Xing picked up a book "Tianyou Pinghuai Book" at will.

The Pinghuai Book is one of the Eight Books. The Tianyou Pinghuai Book means the records of the Tianyou Ancient Kingdom's resistance to void rivers and the management of disasters within its territory.

Zhao Xing had already read many versions, but the preferences recorded in different places were different, and the degree of detail was also different. This mainly depended on the style of the historian.

"The time period recorded in this book is from 22 epochs before the Desolate Domain to 20 epochs before the Desolate Domain, lasting 2. million boundary star years."

"It is considered quite short in history books." Zhao Xing became interested.

The history of the Xuanling Star Domain can be traced back to the Five Emperors period. The Five Emperors era ended, and then Ancient Kingdoms appeared.

The oldest 【Ancient Kingdom】 is about 400 epochs, which connects with the Li Emperor era of the last generation of the Five Emperors period. Before that, it was the unified territory of the Five Emperors, and Ancient Kingdoms had not yet appeared.

The Li Emperor era has been more than 400 million boundary star years ago. The end of the Five Emperors era was the chaotic conquest of the Ancient Kingdom era.

The Pinghuai Book only records two epochs, which is already considered a very short time. Since the time is short, it must be recorded in more detail.

"Tianyou Calendar 4 Yang 1389, Li Star River upheaval, a total of 340 million livable boundary stars and star-lands were destroyed by the Li Star River. The disaster of void turbulence affected 3, 50 star sectors near the river in the Tianyou Ancient Kingdom."

"Hmm? The Li Star River change actually collapsed more than 3, 00 star sectors. This disaster is big enough." Zhao Xing thought to himself.

The rivers in the void layer are 'Qi' condensed into liquid. It may be spiritual energy or poisonous gas. It is a mixture.

If there is more spiritual energy and the stability coefficient is high, it is called a void river.

If there is more harmful Qi and the chaos coefficient is high, it is called void turbulence.

Generally speaking, the rivers in the Xuanling Star Domain are stable, and such upheavals have rarely happened.

The last large-scale void river change was the Yue Luo Mausoleum that Zhao Xing experienced in the 'Phantom God Star System', which was washed out by the void river.

It's just that in terms of intensity, the situation of Yue Luo Mausoleum was far inferior to the Li Star River.

"Tianyou Calendar 4 Yang 1390, 46 river generals and Pinghuai envoys in the river area were executed..."

"Tianyou Calendar 4 Yang 1423, after the governance of the Tianyou Agrarian Supervision, the Li Water Star River upheaval still could not be calmed down, and the source of the upheaval could not be found..."

The Pinghuai Book has a territory map for comparison. Zhao Xing looked at it, and the southern part of the Tianyou Ancient Kingdom territory map was already empty, and the map was dark. This means that a large number of boundary stars and star-lands disappeared, which is a vacuum zone.

Only eye-catching signs were marked on the edge of the disaster area. Some represented violent void wind vortexes, and some were lightning marks, representing terrifying thunder areas.

Dim starlight is the territory where the disaster degree is relatively weak. This situation had not improved at all until Tianyou Calendar 4 Yang 1550, and instead expanded further.

"I didn't expect that the Tianyou Ancient Kingdom had encountered such a big natural disaster in history." Zhao Xing looked at the current Tianyou Ancient Kingdom map and compared it, finding that it was about one-tenth smaller.

In the south of the Tianyou Ancient Kingdom, the missing area has become a Desolate Domain, named Li Water Desolate Domain.

Obviously, that disaster was ultimately not saved and restored.

This aroused Zhao Xing's great curiosity.

"The Tianyou Ancient Kingdom is one of the top ten in the Ancient Kingdom Alliance, and it was unable to solve the disaster of the Li Star River."

"What is the reason?" As an Agrarian Officer, Zhao Xing was very curious about natural disasters.

Especially the name Tianyou Ancient Kingdom touched his nerves.

Because in the modified memory, the last Xuanling Dharma Assembly was hosted by the Tianyou Ancient Kingdom.

Du Yun also became a genius of the Tianyou Ancient Kingdom, including the root of the old Qing before becoming a god—the Purple God Mansion also completed the migration.

With questions, he continued to read, and Zhao Xing flipped the "Pinghuai Book" to halfway before seeing the reason.

"The upheaval of the Li Star River lasted for a whole epoch, and it was not until the end of the 22nd epoch before the Desolate Domain that the Agrarian Officer of the Tianyou Ancient Kingdom found the cause of this disaster."

"The source of the Li Star River is in the 29th Ren of the Dao Manifestation Layer in the north of the Tianyou Ancient Kingdom. Great Agrarian Officer 'Yue Hongdao' discovered that at the source of the Li Star River, a branch of a plant life that had never been seen before appeared..."

"It branches, spreads, the lower part lies on the Dao Ancient Layer, and the lowest section has adventitious roots. The leaves are opposite; sessile or with very short petioles that embrace the stem."

"The leaves are oblong to oblong-elliptic, the tip is acute or blunt, the edges have dense and awned serrations, the edges are slightly keratinized and slightly curved and thickened, and both sides are hairless. The raceme is terminal..."

"Flowers are opposite, with short stalks; bracts are lanceolate, flower stalks are striped, hairless; calyx is deeply lobed, lobes are lanceolate, with sharp thorns, edges are membranous; corolla is small, light purple or white..."

"After verification by the Primordial Realm, this unknown plant is the legendary 'Spirit-Devouring Grass', which is comparable to the combat power of a human demigod after growing up!"

"It is precisely because it continuously devours the 'spiritual energy' of the deep void of the Li Star River that the entire section of the Li Star River began to develop toward a chaotic river..."

"Hiss, such a terrifying natural disaster was actually caused by a legendary plant life?" After reading it, Zhao Xing couldn't help but be shocked. "It is actually comparable to the demigod level of the human race."

Zhao Xing immediately checked the ancient books of the Primordial Realm through the star-mirror. Regrettably, the Spirit-Devouring Grass had gone extinct in the long river of history.

The last one appeared in the 5th epoch before the Desolate Domain, and now the Primordial Realm only has its residual limb specimens, not living bodies.

"In the long river of history, I don't know how many powerful plants were born, but unfortunately many of them are extinct." Zhao Xing sighed with regret.

The Self-Nature faction Agrarian Officers in ancient times might not have as many unique skills as they do now, but most of their plant soldiers were very strong. The reason is that the difficulty of obtaining plant soldiers is different.

Like the highest quality one on Zhao Xing now is the Emperor-level Seven-Domain True Spirit Bamboo, which was a gift from Emperor Five Poisons, but it is only a seedling.

Emperor-level soldiers in the growth period, Five Poisons cannot afford to send, he himself is lacking!

As for the legendary plants comparable to demigods, I am afraid there is only Ancient Luo River.

Divine plants like the Primordial God Tree are not anyone's soldiers; they are the foundation of the Primordial Realm.

"This time the Boundary Transmission Tower opens, I am afraid that many Agrarian Officers in the Primordial Realm will go." Zhao Xing thought to himself. "According to the replacement rules of the Boundary Transmission Tower, if you are lucky enough to encounter a legendary seed and seedling that has not grown up, maybe you can bring it back with just a low-grade Reincarnation Daoist weapon, or even an Origin Divine Weapon."

"The earlier the time, the higher the possibility of encountering powerful plant soldiers."

After all, according to the universe theory of the Self-Nature faction, the native species in the Origin stage and Primordial stage must be stronger than those in the Myriad Phenomena stage. The Myriad Phenomena stage is more suitable for breeding derivative species.

The Boundary Transmission Tower reappeared in the world, and soon attracted great attention, and even the popularity of the Desolate Domain development was overshadowed. A large number of powerhouses were discussing going to the Scholar City.

Not only history scholars and Agrarian Officers yearn for it, but other professions are the same, especially the sewer professions, such as musicians and dancers. Who doesn't want to obtain those lost musical scores and dances?

Even the Great Zhou sent people back to Jiachen Pass from the Wangliang Star Sector.

When Zhao Xing was preparing to set off, he learned that Martial Emperor Ji Che, Liu Tianning, and Yun Tiandao were all going to the Scholar City to enter the Boundary Transmission Tower.

"Fifth brother, are you going too?" Zhao Xing asked.

"Big brother, of course I have to go." Ji Che looked at Zhao Xing on the Flower Chair, his eyes a bit distressed. "Ji Si said that in the Boundary Transmission Tower, one can even go to the history of the Five Emperors era. Of course, I have to go and see how the five generations of Luck dynasties on the Xuanling Star Domain operated."

"Brother Yun, you are a Heavenly Timing faction Agrarian Officer, what are you going for?" Zhao Xing looked at Yun Tiandao again.

"I mainly want to see those large-scale natural disasters in history." Yun Tiandao took out a book from his arms. "Many terrifying natural disasters are rarely seen in the star domain, and I don't know how many years they meet once, but in the boundary transmission, they are very common."

He was actually also reading the "Pinghuai Book", and his idea coincided with Zhao Xing's.

As for Master Liu Tianning, there is no need to ask. He is a Self-Nature faction, and I am afraid he has the same idea as most Self-Nature faction Agrarian Officers.

"Besides that, I also want to see what my hometown in history looked like." Yun Tiandao pointed to the map of the Xuanling Star Domain.

Everyone looked over and found that Yun Tiandao was pointing to the Chenluo Desolate Domain.

Zhao Xing's heart moved, and he also had great curiosity.

The Chenluo Desolate Domain was not a Desolate Domain before, so what was the Xuanhuang Realm before?

The crowd looked over and discovered that Yun Tian Dao was referring to the Chen Luo Desolate Domain.

Zhao Xing's heart stirred, and he also developed great curiosity.

The Chen Luo Desolate Domain was not a desolate domain before; so what was the Xuanhuang World like before?
