Chapter 438

In the original story, a few months before the Mirage set sail, the Yin-Yang School had done one thing.

That was to launch a secret conquest against Shushan together with Meng Tian's army.

In that battle, Shushan was destroyed, and many supreme treasures were lost one after another, including the Divine Tree Fusang, which the Shushan tribe had served for generations. It is said that the Fusang divine tree was a portal connecting the realms of gods, humans, and the underworld. Of course, this was a legendary claim, and no one knew if it was true or false, but the Fusang tree in the original story was indeed quite magical.

It was transported from Shushan to the Mirage and planted there. For such a long time, not only did it not die, but it lived on well.

At this moment, realizing that the most critical things were still missing to find the whereabouts of the Seven Luminaries of the Azure Dragon treasure, Su Xuan thought of Shushan immediately.

"So, in the end, is it still impossible to bypass Shushan?"

Su Xuan's eyes flickered, and he whispered to himself.

The entanglement between the Yin-Yang School and Shushan was deeper than he had imagined.

Five hundred years ago, a group of Taoists rebelled and established the Yin-Yang School. At the beginning, these people were hunted down by the Taoist school and fled everywhere in the world, eventually escaping to the Shu region.

At that time, the passage between the Qin State and the Shu region had not yet been opened, and even the Taoist school did not know their whereabouts after they escaped to the Shu region.

The Shu region was extremely mysterious to the Central Plains. Hidden there was a mysterious force that had been passed down for who knows how many years, named "Shushan." Shushan referred to both the mountains in the Shu region and the name of this mysterious tribe.

Since the ancient times, they had been rooted in the vast mountains, guarding certain secrets.

The people of the Yin-Yang School used certain methods to deceive them and gain their trust, managing to join the Shushan tribe. However, the so-called joining was only temporary; with their joining, some people in Shushan began to yearn for the outside world.

Finally, like the Taoist school, Shushan experienced an internal conflict.

A portion of the Shushan people left Shushan with the Yin-Yang School people and later arrived in the Central Plains.

This was also the reason why witchcraft existed among the many techniques of the Yin-Yang School; witchcraft originally came from the Shushan tribe.

It could be said that the Yin-Yang School was essentially a new sect born from the fusion of the strengths of two schools. Of course, in terms of origin, the Yin-Yang School was still closer to the Taoist school; it only integrated some of Shushan's witchcraft during its development and growth.

It was also because of this reason that the relationship between the Yin-Yang School and Shushan was not very good.

Because the Shushan force had always been hidden in the deep mountains and did not take the initiative to find trouble with the Yin-Yang School, and because the Yin-Yang School was in the wrong and was indeed weak in its early years, they did not dare to return after fleeing Shushan, let alone take the initiative to provoke the Shushan force.

Of course, that was back then; today is different from the past.

After Su Xuan took charge of the Yin-Yang School, the strength of the Yin-Yang School rose rapidly. It could be said that if Su Xuan were willing, destroying the Taoist school on Mount Taiyi and replacing it would be an easy task, but he did not do so.

Similarly, Shushan, having been self-secluded for many years and never communicating with the outside world, had long since fallen behind the times. For the current Yin-Yang School, it really didn't count for much.

After knowing where to look for the final object to find the Seven Luminaries of the Azure Dragon treasure, Su Xuan put away the seven bronze boxes and the Phantom Sound Box. The Phantom Sound Box was a supreme treasure of the Yin-Yang School; even though it had lost some value now that the bronze boxes were cracked, just by virtue of its ability to play thousands of magical sounds, it was a well-deserved treasure for the Yin-Yang School.

As for these bronze boxes, Su Xuan decided to keep them. After all, they were artifacts that had circulated in the world for a thousand years, with extraordinary value and great commemorative significance.

After finishing these things, he took the tortoise shell and went to the Zhangtai Palace.

"How does the State Preceptor have time to come to me? I heard that the State Preceptor has been cracking the Seven Luminaries of the Azure Dragon during this time; has there been a result yet～～?"

Seeing Su Xuan, Ying Zheng asked curiously.

During this time, he had actually summoned Su Xuan to the palace to preach for him.

But he learned that Su Xuan was busy.

So, he did not continue to force Su Xuan to enter the palace. Of course, when Su Xuan gave Ying Zheng an answer, he also told Ying Zheng what he was doing.

This made Ying Zheng very curious about whether Su Xuan could crack that secret.

The Seven Luminaries of the Azure Dragon!

This secret had been circulating in the world for a thousand years. It was said that whoever could crack the secret of this object would possess the powerful power to control the world.

Ying Zheng sneered at this.

The Qin State had already unified the world, and he did not rely on the so-called Seven Luminaries of the Azure Dragon. In the end, human determination could conquer heaven; the rumors of the Seven Luminaries of the Azure Dragon were just a scam.

Of course, since this object had been circulating for so many years, he also wanted to know what its true secret was.

"I have already found the last bronze box and cracked the secret of the Seven Luminaries of the Azure Dragon!"

Su Xuan did not hide the fact that he had collected all seven bronze boxes; after all, he had asked for the Qin State's bronze box from Ying Zheng in the first place.

"Oh?"
