To be the best leader, you must also be the strongest leader!

Seeing Wu Muyan's hesitant expression, Sun Yi knew that Wu Muyan must have some good things, but he also had a lot of good things in Qingyun Sect.

"What? Is it difficult?"

Wu Muyan hesitated for a moment and sighed, "My Wu family was wiped out by the Sanyuan Sect because of a Mysterious Spiritual Array Codex. Zhao Chengfeng and the others were hunting me down because of this Mysterious Spiritual Array Codex."

"This Xuanling Formation Code is the most precious treasure of our Wu family. Even within the family, only a few direct descendants can read it."

"Haha, don't worry. Just bring out the Xuanling Formation Codex. I won't let you suffer any loss. How about I exchange something with you?"

In fact, Sun Yi could force Wu Muyan to hand over the Xuanling Formation Manual, but Sun Yi did not intend to do so. He wanted Wu Muyan to join Qingyun Sect sincerely as he was such a talented person.

"The Xuanling Formation Code is the most precious treasure of my Wu family. Please forgive me, Master." Wu Muyan obviously refused. After all, this was the most precious treasure of their family.

For this treasure, he is the only one left in the entire Wu family.

"I'll trade you the Heavenly Soul Liquid, which can strengthen your soul several times." Sun Yi looked at Wu Muyan calmly.

Wu Muyan's eyes widened instantly: "What? You have Heavenly Soul Liquid?"

"Haha, why do you think my soul is so strong?" Sun Yi smiled.

"How is it? This is a treasure that even Nascent Soul cultivators desire very much. It is enough to strengthen your soul several times."

"This..." Wu Muyan's heart was shaken. Of course he knew about the Heavenly Soul Liquid. It was a top-grade treasure that could repair and strengthen the soul. It was extremely precious. Even cultivators in the Nascent Soul stage rarely possessed it.

"If the Heavenly Soul Liquid is not enough, I will give you the secret method to open up the five Dantians, which will allow you to add five Dantians in your body." Sun Yi spoke again.

"You are willing to share even this secret method?" Wu Muyan looked at Sun Yi with wide eyes.

Sun Yi curled his lips and thought to himself that everyone in my Qingyun Sect knows this secret method, and you will know it when you get to Qingyun Sect.

"How about it? If that's not enough, I can also give you a Purple Extreme Wild Flame and teach you the secret method of refining the Purple Extreme Wild Flame." Sun Yi added another advantage.

"You are willing to give me even the spiritual fire?" Wu Muyan looked at Sun Yi in disbelief.

Sun Yi smiled, then waved his right hand, and a set of third-level, ninth-grade Qingyun battle armor appeared in front of Wu Muyan: "How about another set of third-level, ninth-grade Qingyun battle armor?"

"Deal!" Seeing the brand new third-level, ninth-grade Qingyun battle armor that Sun Yi took out, Wu Muyan agreed without hesitation.

Sun Yi felt amused and thought that he would give these things to Wu Muyan after he returned to Qingyun Sect.

"Put this Qingyun battle armor away first. I'll give you the other things when we return to the sect. Bring out your Xuanling Formation Manual and let me see it."

Sun Yi directly handed the third-level, ninth-grade Qingyun battle armor to Wu Muyan. Wu Muyan quickly took it and casually took out a golden jade slip and handed it to Sun Yi.

"This is the Xuanling Formation Code. Take a look at it first."

Holding the third-level, ninth-grade Qingyun battle armor, Wu Muyan began to study it carefully. He had seen the power of this thing with his own eyes before. Not only was it exquisitely shaped, but it was also extremely powerful.

Sun Yi began to study the Xuanling Formation Book in his hand. His spiritual consciousness entered the jade slip, and the next moment a vast formation book appeared in front of Sun Yi.

Before, Sun Yi had been reading the ancient books of Qingyun Sect and had read a large number of books on formations. Later, he obtained the books of Heifeng Village, Xieling Valley, Zhou Family and Xuanyin Sect, and Sun Yi read a lot of content about formations in them.

However, compared with the Xuanling Formation Manual in front of him, the formation manuals he had read were completely different.

This Xuanling Formation Classic has vast content, and the analysis of formations is very detailed. It is like a comprehensive formation manual. As long as you have a certain talent for formations, your formation level can be greatly improved by studying this manual a little.

Moreover, Sun Yi discovered that the Xuanling Formation Codex was very systematic, and was divided into the first-level formation chapter, the second-level formation chapter, the third-level formation chapter, the fourth-level formation chapter, and even a sealing section at the end. However, the sealing force was too strong, and the content at the end could not be seen at all.

With Sun Yi's current level of formation skills, he couldn't even comprehend the fourth-level formation, let alone the sealed part at the end.

However, after just a quick look at the previous content, Sun Yi knew that he had really picked up a treasure this time. With this Xuanling Formation Classic, his formation skills will definitely improve by leaps and bounds.

"Indeed, no wonder the Sanyuan Sect would attack your Wu family. This Mysterious Spiritual Formation Code is incredibly profound. But what is the content of the sealing part at the end?"

Wu Muyan shook his head: "This is an ancient jade slip. Even our Wu family's ancestors don't know what the seal on the back is. The power of the seal is too strong. Our Wu family's Yuanying stage ancestors have tried many times and have no way to break the seal."

"This ancient jade slip was obtained by you from the ancient ruins, right?"

Wu Muyan nodded and said, "This ancient jade slip was accidentally found by my ancestor from a relic two thousand years ago. When he saw the mystery of the formation in this jade slip, he concealed it and did not hand it over to the Tiansheng Palace. This is the biggest secret of our Wu family."

"I see. Fortunately, you didn't hand it over to Tiansheng Palace, otherwise we would be in trouble." Sun Yi couldn't let go of the ancient jade slip.

With this book on formations, he had a premonition that the Qingyun Sect's Formation Hall was about to take off.

"The design of your Qingyun battle armor is truly ingenious. The coordination of the formation is quite good. It has speed, defense, and can even use spirit stones as external power. I have never seen such a design before."

"This is the highest masterpiece of our Variety Art Hall."

"How are your injuries? If they've mostly healed, we should head back. With you joining us, research on the Body Tempering Blood Pool project will surely be much easier."

Sun Yi has already thought of Wu Muyan's next arrangements. Such a formation genius must be brought into the research project team of the Body Tempering Blood Pool. His understanding of formations is far superior to his own, and formations are the most critical part of the Body Tempering Blood Pool. Sun Yi believes that with Wu Muyan's joining, the Body Tempering Blood Pool project will surely make rapid progress.

"What is the Body Tempering Blood Pool Project?" Wu Muyan looked at Sun Yi in confusion.

"Haha, keep it secret for now. You'll know when you return to the sect with me." Sun Yi smiled without explaining.

"After taking the healing pills you gave me, my injuries have temporarily stabilized, but it will take some time to fully recover."

"Okay, I'll go see how they've managed Falling Star City. If everything is stable, we can go back."

"I'll go with you to take a look."

Sun Yi nodded, then took Wu Muyan out of the Qingyun Taoist Palace and began to inspect the governance of Luoxing City.
