Chapter 885

If the Nine Provinces seal is opened, heaven and earth will gradually recover, returning from the Age of Dharma Decline to an era full of spiritual energy, and the extraordinary will also return. Although the passage between the divine and human realms was severed as early as the time of Emperor Zhuanxu, this does not mean that the common people in the human realm have no threats.

Although immortals and gods cannot reappear in the human realm, those prehistoric beasts may not necessarily be the same.

They originally existed on the earth and brought many disasters to the common people in the human realm.

It was Emperor Yu who established the Nine Provinces seal and banished the Mountain and Sea Realm, so these threats gradually disappeared. Once the Nine Provinces seal is broken, it means that the banished Mountain and Sea Realm will return. They will reappear in the form of secret realms, and then turn from virtual to real, gradually overlapping with the human realm step by step.

Strictly speaking, this sea area can also be considered one of the banished Mountain and Sea Realms.

However, this sea area is devoid of life and is a place of dead silence. Although they encountered Xiang Liu, that was merely a fierce spirit formed by the residual resentment of Xiang Liu. Strictly speaking, it does not count as a living creature. Only this last Penglai Xianshan, because of the barrier, was able to retain some vitality.

This vitality is only for vegetation; there are still no animals.

But this is only this sea area; no one knows if there are still prehistoric beasts alive in the other Mountain and Sea worlds.

Strictly speaking, in the current world, it has not been too long since the era of Emperor Yu, only a little over a thousand years.

In over a thousand years, some prehistoric beasts may not have gone extinct.

If the Nine Provinces seal is rashly opened, causing the banished Mountain and Sea Realm to return, at a time when the extraordinary has gone far away and human powerhouses are far inferior to those of the ancient era, these prehistoric beasts are likely to bring about a great catastrophe.

This may also be the reason why Jiang Taigong ultimately chose to die here rather than open the Nine Provinces barrier.

The reason is that the era he lived in was closer to the era when Emperor Yu banished the Mountain and Sea world.

The hidden dangers of opening the Mountain and Sea Realm at that time would also be greater.

However, despite the hidden dangers, Su Xuan has already decided to open the Nine Provinces barrier.

He possesses immortal techniques, and earlier he even inherited the techniques of immortal cultivation in the Yin-Yang School. If the Nine Provinces barrier is opened and the spiritual energy of heaven and earth recovers, perhaps he can turn this world into a xianxia world.

At that time, as the existence who helped the world ascend, his harvest would definitely not be small.

However, before opening the Nine Provinces barrier, he must also make many preparations to minimize the hidden dangers as much as possible.

"I see!"

Yanfei did not know Su Xuan's true thoughts. After hearing Su Xuan's answer, she nodded gently.

No matter what Master Xuantian is worried about or what decision he has made, she chooses to silently support Master Xuantian.

In the underground palace, there are not many things.

To be precise, apart from the sword and the cauldron, there is nothing else.

Only Yanfei is proficient in ancient texts, so she could slightly understand some of the characters on the cauldron lid. The others focused their attention more on the Xuanyuan Xiayu Sword.

The transparent liquid in the Yellow Emperor's precious cauldron did give rise to some conjectures, but because they arrived late, they did not know the truth of it, nor did they know that this was originally a cauldron of life essence, and its original color was also scarlet like blood. It had only become this way now because Su Xuan had absorbed it clean.

After staying in the underground palace for a while, everyone went out again and wandered around on Penglai Xianshan.

Xiao Yu acted as their guide during this process.

Because she had come to Penglai Xianshan with Su Xuan earlier, Xiao Yu had stayed on this immortal mountain for several more months. She had already explored most of this immortal mountain, and with her pointing the way, it saved everyone from having to explore it again.

Among them, Xiao Yu focused on leading everyone to visit several ruins she had discovered.

After seeing these ruins that might have been left by the immortal sages of the ancient era, everyone's eyes became brighter and brighter, and then they carefully studied these ruins, hoping to discover some traces left by the ancient immortals.

After all, they were left by immortals. If the immortals had the intention, could they leave behind a scroll of ancient cultivation techniques that they could use to achieve the Dao of Immortality?

Unfortunately, they were disappointed; there was nothing.

While everyone was wandering around on Penglai Xianshan, Duanmu Rong fell into a state of obsession. She constantly researched the various strange flowers and fruits on the island, and she did not even let go of the weeds by the roadside. Although some weeds were species that could also be seen in the Central Plains, this was Penglai Xianshan, and they grew on Penglai Xianshan; no one could say for sure if they had any special properties.

Duanmu Rong was very busy. It could be said that in her life, she had never been this busy. After arriving here, she felt as if she had arrived in a treasure house. Although she was very tired, if she could thoroughly research these plants on Penglai Xianshan, she could foresee that her medical skills would reach an unprecedented realm.

At first, only Duanmu Rong was busy.

Finally, Zinu, the Shao Siming, and Xiaoyi from the Wood Department also came to help Duanmu Rong.

They started helping Duanmu Rong at Su Xuan's request.

According to Su Xuan, "There are so many plants, 423 Duanmu Rong alone cannot research them thoroughly. And these plants grow on Penglai Xianshan; no one knows if they can be planted after taking their seeds back. Even if they are planted, they probably won't have the same medicinal properties as they do on Penglai Xianshan."

"Therefore, we must take advantage of the time we are still on Penglai Xianshan to thoroughly research their properties and distinguish which are useless weeds and which are useful miracle drugs."

"If they are miracle drugs, we can take their seeds back to try planting them, and at the same time, pick some to see if they can be refined into elixirs!"

It was these words of Su Xuan that made Zinu and the others realize the heavy burden of the task.

This time, they were able to reach Penglai Xianshan after spending a long time, and they also needed to be in a specific timing to be able to step into this sea area. No one knew if they would have the chance to come here again in their lifetime.

So they must cherish this opportunity and convert everything encountered on the immortal mountain into harvest as much as possible.

Even if these strange flowers and fruits on the immortal mountain cannot be transplanted to the Central Plains and cannot be planted in the Central Plains, they must be refined into elixirs as much as possible, so that this trip will not be in vain.

You know, the immortal mountain has been isolated from the world for a thousand years. These medicinal materials, if placed in the Central Plains, would without exception be medicine kings with thousands of years of medicinal age.
