Tang Feng came to the library building, and Mu Qing was already waiting for him. During this time, Luo Yu was not there, and he was taking care of the four-story library.

"Elder Mu. ”

Tang Feng bowed to Mu Qing: "I'm tired of Elder Mu choosing a book about the Demon Realm for me." ”

Mu Qing shook his head: "I also want to see how you found out." ”

Tang Feng had found out the location of the Three Holy Grasses by himself before, and he thought that Tang Feng must have some special method.

Other Tang Feng didn't have any special methods, he was just good at sorting out and analyzing, going through all the information he had seen in his mind, and then selecting similar ones and finding clues from them.

Mu Qing: They have read a lot of books, but they are not as good at analyzing as Tang Feng.

Tang Feng found out the books about each Demon Venerable, and then found out some of their events from the biographies or travelogues, through their descriptions, sorted out what exercises they used, cultivated to geometry, and then eliminated some irrelevant information, and finally found the news about "Nine Turns Back to the Soul".

"Nine Turns Back to the Soul" is just like its name, there are nine turns, each style is more powerful than the previous one, and the more demonic energy is consumed, so except for the first generation of Demon Venerable, no one else has practiced it all, and there are very few people who know this exercise, because since the sixteenth generation of Demon Venerable, "Nine Turns Back to the Soul" has been lost, and no one knows its whereabouts, but Xie Liqing found it, according to the description in the book, Xie Liqing has now practiced the fifth or sixth style.

After a month of sorting, Tang Feng recorded it with pen and paper and brought it to Mu Qing: "Elder Mu, look. ”

Mu Qing took it and looked at it, a little surprised: "I didn't expect you to find out!"

Mu Qing had also read these books, but he had never linked these small events together, but he didn't expect Tang Feng to actually piece together hundreds of small details, and really find out Xie Liqing's magic skills.

Tang Feng nodded: "As long as you make good use of this information, even if it is a small matter, you can find it." ”

Mu Qing said with a smile: "If Qi Yunlou knew that you had such an ability, he would definitely try his best to dig you up!"

Tang Feng shook his head: "Qi Yunlou is the number one leader in collecting intelligence, how can I be on a par with them." ”

Mu Qing: "But this time you found something they didn't find!"

Tang Feng looked at Mu Qing: "It's just that they didn't delve into this aspect this time, otherwise they would have found it a long time ago." ”

Tang Feng was right, when Su Rang proposed to use the talisman seal to control Xie Liqing's magic skills, Qi Yunlou was looking for all kinds of books and materials, but some books were collected in the libraries of various major sects, and they didn't have a chance to see them, so they were a little late.

Ling Yunzhi was very surprised after receiving Zeng Ziyan's news, and when Qi Wanyi, the sect leader of Qi Yunlou, came with the collected information, Ling Yunzhi was even more shocked.

Qi Wanyi: "Master Ling, I have already found what exercises Xie Liqing practiced!"

Ling Yunzhi looked at Qi Wanyi: "I already know." ”

Qi Wanyi was very surprised: "How do you know? As soon as I received the news, I came quickly, and no one else came first!"

Ling Yunzhi thought about it, and still told him about Tang Feng.

Qi Wanyi was shocked and said, "I didn't expect Young Master Tang to have such an ability, a few days earlier than our Qi Yunlou." ”

Ling Yunzhi nodded: "Tang Feng, this kid is really good, you must meet him if you have the chance." ”

Qi Wanyi also nodded, looking at the paper in his hand: "Since that's the case, then I'm useless, right?"

Ling Yunzhi stopped him: "Let's take a look at the Qi Mansion Master." ”

Qi Wan thought about it, no matter how powerful Tang Feng was, after all, he was only eleven or twelve years old now, and even if he found it, it was possible to find a mistake or a mistake.

The two went to find Wuxiang again, as well as Lei Zhen of the Thunder Sect and Su Rang of the Qingyun Sect, and several people watched together.

Qi Wanyi looked at Tang Feng's summary and was amazed: "This kid is not simple, most of them have been calculated." ”

Wuxiang nodded: "Although there are some discrepancies with Qi Yunlou, it is also very good that he alone can find these." ”

Several people deleted, deleted, and finally determined, Xie Liqing's Lian Gong was indeed the first Demon Venerable's "Nine Turns Back to the Soul", but he had already practiced them all, but the last two styles were a little reluctant, after all, the consumption of demonic energy was quite large. And they also deduced that Xie Liqing had not been transformed into a demon.

The first time the enchantment of Xuandeng Temple was broken, Xie Liqing faced Wuxiang and almost became demonized, if he hadn't finally stopped, I am afraid that he would have become a low-level demon with no reason.

Although Xie Liqing is a hybrid of human and demon and can survive in the demon world, he is always a few points weaker than the purebred demon race, if it weren't for this "Nine Turns Back to the Soul", maybe he would have been killed in the demon world where the weak eat the strong. Xie Liqing was almost demonized before, it was the reason why he didn't transform into a demon, if he had already transformed, then he wouldn't have been demonized at that time.

However, Xie Liqing's ability to complete all the "Nine Turns Back to the Soul" as a hybrid of humans and demons also shows that he is extremely talented. Now that I know his exercises, I have a clue.

Su Rang looked at the paper in his hand: "Since I found it, then I'll go back and try, if the demon clan comes back during this time, it will be troublesome for you." ”

Ling Yunzhi looked at Su Rang: "What Sect Master Su said, now is the time to have the same hatred. ”

Lei Zhen nodded: "During this time, everyone has run in again, our sect's Thunder Array can be combined with the Seven Killing Array of Ling Xiaomen, and the lethality has been greatly improved, even if Xie Liqing comes, he will be pestered for a while." ”

Wuxiang also said: "The Guardian Array can also be fused with the Seven Killing Array, and the defense and attack can be mutually compatible. ”

Su Rang: "Okay, then I'll take my disciples to retreat." ”

Everyone said: "Everything is up to Sect Master Su." ”

Su Rang's side has already started to prepare, and Xie Liqing has also been in the demon world for more than a month.

As Ling Yunzhi and the others guessed, Xie Liqing had not transformed into a demon clan, and every time he used his demon skills, the damage to him was great. Xie Liqing had thought about completely transforming into a demon, but he was reluctant to give up the only thing that was similar to his mother.

Xie Liqing was reluctant to transform before, also because this half of the same bloodline as Heyue, if he was transformed into a demon, he would have nothing like Heyue.

Xie Liqing was in the blood demon pool, the demonic energy around his body was running around, in order to deal with Wuxiang before, he forcibly ran the ninth turn of "Nine Turns Back to the Soul", so the consumption of demonic energy was very large, if he was a demon, it wouldn't take long to recover after returning to the demon world, but Xie Liqing was just a hybrid of humans and demons.

In the past month, Xie Liqing has been soaked in the blood pool, and Wu Shuisheng, who is a demon seed, has also protected the Fa for him, but he still hasn't calmed down the demonic qi. He asked people to find Xing Shen, but it was useless.

Looking at the demonic qi running around, Xie Liqing wanted to make up his mind and transform into a demon.

Xie Liqing thought that he had almost taken the Xuandeng Temple before, and his eyes were cold: The most important thing now is to take down the Eastern Ancient Continent, and the rest will be talked about later, and now there is a replacement.

Thinking of Lan Xin, Xie Liqing felt that it was the most correct decision to bring her to his side in the first place. Lan Xin reminded him of his mother, and now even if he is transformed, there is something to transfer feelings.

Xie Liqing summoned Xing Shen and the Black and Red Devil Envoy: "I'm going to transform now, you can help me watch from the side." ”

The black and red devil envoy nodded, and although Xing Shen was shocked in his heart, he also nodded.

Xing Shen, like everyone else, thought that Xie Liqing had been transformed early in the morning, but thinking that Xie Liqing's identity as a half-demon had made Wuxiang and them have no power to fight back, if they were transformed, they didn't know what kind of level of cultivation they had reached.

Xing Shen wanted to tell Yue Hua about them, but he couldn't leave here, so he could only wait until he came out of the Demon Realm to inform Yue Hua.

And Xinyuan Palace, Lan Xin knew that Xie Liqing would not come to Xinyuan Palace, she was very happy, and ran to Shen Chong every day, although Shen Chong was restricted, but he was not injured every day like before, giving him some respite.

He knew that Lan Xin could no longer cultivate, so he was studying medical skills with Xing Shen, and he also handed over his poison technique to Lan Xin. Although Cui Ya was ruined by the demonic qi and her cultivation was also a little hindered, she was able to run the Xuan Qi, so Shen Zheng taught her the "Five Poison Techniques".

Fortunately, Xie Liqing invited Lan Xin to a music and rhythm teacher, and when Lan Xin was studying, Cui Ya was also studying on the side, so she didn't have to teach her seriously, and it wouldn't attract the attention of the guards. After all, if you follow Shen Zhong in the cell every day to learn music and rhythm, you will soon be suspected by Xie Liqing.

Time passed slowly, Tang Feng was busy clearing his inner demons, Xie Liqing was busy transforming, Su Rang was busy making talisman seals, and Lan Xin and Cui Ya were busy learning the Five Poison Techniques.

The demons of the Demon Realm occasionally harassed the people on the border, and the people resisted, and just like that, another month passed, Tang Feng cleared the demons in his heart, and Xie Liqing also returned to the Xinyuan Hall from the Demon Realm.
