The reason why Li Xuesong lurked in the Western Qin state was that he founded Yunshan school!

Its purpose is to cultivate some of its own strength, to prepare for the future invasion of Western Qin by Shu controlled by Wumen.

The letter Murong Furong wrote to Li Xuesong was also found by Chu Tianshu.

But Chu Tianshu guessed that Murong Furong did not know Li Xuesong's real identity.

The letter even vaguely mentions that the Murong aristocratic family will unite with major, middle and small sects, as well as aristocratic families, to overthrow the rule of the Ji family.

Most of the disciples of Yunshan sect are mountain people nearby, and they have no knowledge of Li Xuesong's identity.

Therefore, Chu Tianshu did not kill innocent people any more.

Through interrogation, he released all those who had not killed or done evil things.

The others were killed by Ji Ruxin!

"Go back!"

Chu Tianshu turned around and left.

The rest followed.

Everyone is excited!

To destroy a sect was something they did not dare to imagine before.

Even if it's just a small sect, it's also a half step of great Xuanshi's master.

Let alone harvest so much.

Jiang Mingsi was most moved. He knew that this time without Chu Tianshu's magic cooperation, everyone would never have killed Li Xuesong.

That's the half step great Xuanshi who almost gathered his fighting spirit. Even if he can't fight, he can definitely run.

But even so, it is full of crisis!

In my heart, I look up to Chu Tianshu more and more.

When he returned, Chu Tianshu was not eager.

He is still pretending to be Chen Hao, sitting on the back of a wolf.

As for the big gray wolf, he gave it to Ji Ruxin.

In his hand, there is a crystal ball big as a fist.

Inside the crystal ball, a black bear shadow is clearly visible.

Chu Tianshu even felt a great spiritual pressure from it!

One side of Jiang Mingsi said: "my Lord, this is the demon crystal. Only a second level monster comparable to Da Xuan master can be bred. The demon soul in it is estimated to be a second level monster!"

"A monster comparable to master Da Xuan? No wonder it can be sold for ten thousand Xuanyu, worth hundreds of millions of taels of silver. However, Li Xuesong didn't buy it himself, did he? It may come from the witch gate! " Chu Tianshu said.

"My subordinates also have this suspicion. After all, it's impossible for a small sect like Yunshan sect to come up with so much money all at once. Even the Da Xuan Dan was given to him by the witch sect!" Jiang Mingsi said.

Chu Tianshu nodded slightly: "how to get the demon soul?"

"After killing the monster, at the first time, take a drop of heart blood and put it into the demon crystal. However, not all monsters will leave heart blood. Many monsters will disperse heart blood and even burn it before they die to fight back!"

"You mean, this demon crystal can be reused?" Chu Tianshu is a wonderful person.

"Yes, the demon crystal can also absorb the blood of the first level monster. The demon crystal itself is extremely precious, and the lowest level is worth thousands of gold. The reason why it can't compare with the demon soul of the same level is that the demon crystal can survive for a very long time, just like a stone. Many sects also use the demon crystal in their transactions."

Through Jiang Mingsi's explanation, Chu Tianshu has an understanding of Yaojing.

The demon crystal was used to store energy before the monster died. However, the energy in the demon will quickly fade and dissipate after the monster died.

Moreover, humans can't use energy directly from the demon crystal.

Otherwise, it's easy to be affected by the ferocity of monsters!

Without the demon crystal of energy, it's just a stone.

However, the demon crystal can also be used as a vessel for storing energy. Many great Xuanshi will have one or two!

Put the extra Xuanqi into the demon crystal, and then use the seal technique to seal. At the critical moment, you can take it out to make up for the lack of Xuanqi in the body.

Jiang Mingsi once again said: "my subordinates think that if Li Xuesong only wanted to refine the first level demon soul, he would have been able to enter the realm of Da Xuan master. However, he wanted to refine the second level demon soul, so he was trapped for such a long time. He also prepared three Da Xuan pills, and caught Miss Liu Wenxuan as a spare medicine cauldron!"

"What's the difference?"

"Refining the first level demon soul needs to be cultivated slowly. If you can refine the second level demon soul, but you don't need to cultivate it, you can directly have a very strong combat effectiveness!" Jiang Mingsi said."What about refining the spirit of the third level monster?" Chu Tianshu is a wonderful person.

Jiang Mingsi said with a smile: "my Lord, the half step master can't resist the spiritual impact of the third level demon soul. There is no one like this. Even in history, it's a rare encounter in a thousand years!"

Chu Tianshu said nothing more.

Put the demon crystal into a wooden box and keep it close to the body.

He picked up a book called overview of pills and looked at it carefully.

Through the contents, Chu Tianshu knew that the original pills were graded.

From level one to level nine!

For example, the quenched body pill he made is only a first-class inferior pill.

However, the cyclone pill, which was used by Xuanshi to attack Xuanshi, belonged to the second level pill.

The Da Xuan pill, which is used to attack Da Xuan master, belongs to the third level pill.

Each level of pills is also divided into three grades.

Under the same level, the higher the grade, the better the quality and efficacy of the pill.

However, there is no record of any Dan prescription in the overview of Dan medicine, but it simply tells the knowledge of Dan medicine.

However, Chu Tianshu also obtained several first-class and second-class prescriptions from Li Xuesong's chamber.

There are also many pills.

The most precious nature is da Xuan Dan.

The three great Xuandan have been brought into Chu Tianshu's arms.

Through perspective, Chu Tianshu can also decipher the prescription of Da Xuan Dan.

In addition, Chu Tianshu also got two primary Dan furnaces and one secondary Dan furnace.

Through the overview of pills, Chu Tianshu realized that he had made pills by mistake before. He was hit by a dead mouse by a blind cat and got it right.

If you use iron pot and stove, you can only produce first-class pills at most.

If you want to refine a higher level of Dan medicine, you must have a higher level of Dan furnace.

Otherwise, it can never be refined.

Because the high-grade pills have high requirements for temperature and sealing.

No matter how sealed the iron pot is, it can't reach that level.

The more he looked at it, the more he felt that the alchemy of the world was so vast and complex that he could not learn it in three or two days.

Unlike Chu Tianshu, who cares about alchemy and practice, Ji rushin is reading those letters one by one.

The more she looked, the colder her face became.

Along the way, she was almost speechless.

Everyone can see that she is not in a good mood!

In order to avoid being torn, Chu Tianshu did not communicate with her too much
