"Tianyu, the fairy energy in this valley is relatively strong. In the past two months, you will practice in this valley. You can first understand the Five Thunder Heavenly Lock and see how much it can be understood. If you don't know the place, you can ask me, and I will explain it to you. I will leave after you fully display the Five Thunder Heavenly Lock." Ren Yunzong broke through the void and brought Yun Tianyu into the small universe realm, and took him to a valley with elegant fairy energy, charming scenery, and full of strange flowers, and said in a low voice.

"Okay!" Yun Tianyu nodded, took out the Five Thunder Heaven Lock Cultivation Scroll, released the powerful soul power and penetrated it, and quickly remembered it.

Now Yun Tianyu's soul realm has reached the level of the first level of Taoist priest, and his memory speed has increased a lot. After about three hours, Yun Tianyu remembered the practice method of the Five Thunder Heaven Lock, and sat cross-legged on the ground to begin to understand it by himself.

When Yun Tianyu retracted the soul power that penetrated into the Five Thunder Heaven Lock scroll, all the soul marks in the scroll immediately disappeared, and the precious scroll turned into a blank scroll.

Yun Tianyu sat cross-legged in the valley with a trace of fairy spirit and suddenly realized for about three days. He encountered many difficulties in cultivation and began to ask Ren Yunzong who was practicing not far away beside him.

Regarding Yun Tianyu's inquiry, Ren Yunzong patiently explained it to him, accelerating Yun Tianyu's comprehension speed. Soon, Yun Tianyu grasped the key points of the Five Thunder Heaven Lock cultivation and tried to use it.

"Yes!" When Ren Yunjun saw Yun Tianyu cast the Five Thunder Sky Lock for the first time in front of him, he miraculously gathered five lightning chains, intertwined not far ahead of him, showing a tangled momentum, revealing a look of surprise.

"Dean, as long as you understand the key points of cultivation, isn't it difficult to use the Five Thunder Heavenly Lock?" Yun Tianyu, who successfully used the Five Thunder Heavenly Lock for the first time, showed a faint smile, looked at Ren Yunzong with a surprised face, and said softly.

The reason why Yun Tianyu was able to use the Five Thunder Heavenly Lock for the first time was closely related to his practice of the Heavenly Thunder Condensation Art and tempering his body in the Heavenly Thunder Valley. With the help of the power of thunder and lightning contained in his body, Yun Tianyu used the thunder attribute Taoist skills much easier.

"You kid is so perverted. Okay, since you can already cast the Five Thunder Heaven Lock, I won't accompany you. I have been practicing hard in the past two months. When the day of departure comes, I will call you." Ren Yunjun glanced at Yun Tianyu, who had been able to cast the Five Thunder Heaven Lock in less than five days, shook his head gently, and his body flashed slightly, and disappeared in an instant.

After Ren Yunzong teleported away, Yun Tianyu practiced the Five Thunder Heavenly Lock for two more days. He felt that he could skillfully use the five bound sky thunder chains and summoned the Misty Butterfly Emperor, hoping to use the power of Misty Butterfly Emperor to help crack the mysterious rusty copper piece he had auctioned at the Wenren Family Auction to see what the secrets were inside.

However, the moment when the Butterfly Emperor was summoned by Yun Tianyu, he was immediately attracted by the fairy energy absorbed in the valley. The strange flowers the size of the bowl were flapping their beautiful wings and said with a pleasant voice: "Master, where are we? Can I absorb the power of those strange flowers?"

"How can the Misty Butterfly Emperor? Those strange flowers can increase your own strength?" Yun Tianyu asked in surprise when he heard the Misty Butterfly Emperor's inquiry, because the higher the Misty Butterfly Emperor's level, the greater the help it will be.

"Well! I feel that the power contained in those strange flowers is a fatal temptation to me and can help me further transform." The mysterious Butterfly Emperor flapped his beautiful wings and responded.

"Since that's the case, then you can swallow the power contained in those strange flowers. I will first merge these two balls of soul real fire." Seeing that the Butterfly Emperor was eager to devour the strange flowers and increase his own strength, Yun Tianyu put away the rusty copper pieces and took out the two balls of burning soul real fire.

"Thank you, master, then I'm not polite." Yun Tianyu agreed. The Butterfly Emperor immediately flapped his beautiful wings and flew to the strange flowers the size of a bowl growing on the mountain wall, releasing green silk, penetrated into the strange flowers, and quickly absorbed the essence of the strange flowers.

"Huh, soul devour!" When the Butterfly Emperor devoured the strange flowers to increase his own strength, Yun Tianyu immediately used the Thousand Hands Soul Technique, condensed 150 fire soul hands and began to slowly devour two balls of burning soul real fire.

When Yun Tianyu endured the severe pain of his soul and controlled the Fire Soul Hand to swallow the two balls of soul real fire one after another, Yun Tianyu felt that his soul had grown a lot, and immediately used the Thousand Hands Soul Art to melt the power of the soul real fire, and began to split and form a new Fire Soul Hand.

After about five days, Yun Tianyu, who was running the Thousand-Handed Soul Art at high speed, finally completely fused two balls of soul real fire, forming fifty new fire soul hands, making the number of condensed fire soul hands reach 200.

The number of Fire Soul Hands has increased. Yun Tianyu found three materials for refining first-level heavenly beast talismans in the Qiankun Ring of the Three Veners of the Silver Palace. According to the experience of refining beast talismans in the brain, he tried to refining first-level heavenly beast talismans.

However, although Yun Tianyu's soul strength reached the level of the first-level Dao Zun and the Fire Soul Hand evolved to a number of 200, because Yun Tianyu had never refined the first-level Heavenly Beast Talisman, he did not grasp the flame conversion after refining it twice in a row, which eventually led to the failure of the beast refining talisman.

"Tianyu, although I know nothing about beast refining talismans, I think that when you just refining the beast talisman, you don't have enough control over the flames. Now don't rush to continue to refine the first-level heavenly beast talisman. You first find ten high-temperature-resistant materials. I will guide you to practice flame control." Two consecutive failed beast talismans, Yun Tianyu immediately sat cross-legged and sorted out his failed experience. However, just as Yun Tianyu was preparing to refine the first-level heavenly beast talisman for the third time, the voice of the great devil sounded in his mind.

"Okay!" Hearing the voice of the Great Demon King, Yun Tianyu immediately found ten high-temperature-resistant materials. Under the guidance of the Great Demon King, he controlled the Fire Soul Hand to release powerful soul flames and practice controlling the flames.

"Master, I'm going to evolve. When I evolve successfully, I will help you lift the ban in the copper piece." Just as Yun Tianyu was under the guidance of the Great Demon King and his control over the flames became stronger and stronger, the Misty Butterfly Emperor, who had absorbed the essence of dozens of strange flowers, flew back slowly and said softly.

"Okay!" Yun Tianyu nodded, put the soon-to-evolved Butterfly Emperor into the Lei Ze ring, and continued to practice control over the flames.

When Yun Tianyu controlled 200 fire soul hands and melted hundreds of beast-refining talisman materials that were resistant to high temperature but not high value, he felt that his control over the flame had reached a completely new level. He became much more skillful in the control of flames and began to try to refine the first-level celestial beast talisman for the third time.

When refining the first-level heavenly beast talisman for the third time, under Yun Tianyu's precise flame control, the beastly talisman material was quickly extracted from the essence, and the beast soul was easily extracted by him. However, during the process of soul fusion, Yun Tianyu encountered great resistance again. After persisting for several hours, he still failed.

However, Yun Tianyu failed to merge the soul, but he gained a lot of experience. He immediately sat cross-legged on the ground, combined with the large amount of experience in his mind, and found the problem.

After about half a day, Yun Tianyu felt that he had found the problem of failing to refine the first-level heavenly beast talisman, so he took out another piece of material to refine the first-level heavenly beast talisman and began to refine it.

This time, Yun Tianyu felt that the refining process was much smoother, and all the difficulties encountered in the early stage were solved. About three hours later, a beast talisman emitting a light blue light appeared in the hands of two hundred fire souls.

"Huh, it's finally successful!" Looking at the beast talisman emitting a light blue light in front of him, Yun Tianyu showed a strong look of joy.

"Tianyu, although you have successfully refined the first-level heavenly beast talisman this time, if you want to win the championship in the four major academies, you probably won the first-level heavenly beast talisman with such powerful power. "Just as Yun Tianyu was immersed in the joy of refining the first-level heavenly beast talisman, the voice of the great devil sounded again.

"I understand that I am planning to refine the human-faced ghost spider king beast talisman in the competition of the Four Great Dao Courts. If it can be refined, with the powerful attack power of the human-faced ghost spider king, it should be able to win the championship." Yun Tianyu nodded slightly and said.

"Although the strength of the human-faced ghost spider king is a top-level existence among first-level celestial beasts, you must also be prepared to refine the second-level celestial beast talisman. After all, what the royal family has mastered is not something you can imagine. So during this period, I suggest you to sort out your experience in refining the second-level celestial beast talisman in your mind and make a preparation." The Great Demon King suggested.

"Second Level 2 Heavenly Beast Talisman! Well, I'll sort out my experience!" Yun Tianyu followed the advice of the Great Demon King and spent a few days to sort out his experience in refining the second-level Heavenly Beast Talisman. He also took out a piece of material for refining the second-level Heavenly Beast Talisman from Song Qingfeng Qiankun Ring and tried to refine it once.

Although the final refining failed, Yun Tianyu gained a lot of things through this failure, combined with the experience of the second-level celestial beast talisman that he remembered in his mind.

Just as Yun Tianyu was silently sorting out his memory experience in his mind, he suddenly felt that the Butterfly Emperor had refined the absorbed essence of the strange flower, successfully transformed into a second-level celestial beast, and released it.

"Thank you, Master, take out the rusty copper piece, I'll help you break the ban inside!" After the level was increased, the mysterious Butterfly Emperor, whose colorful light was flowing on his body, said excitedly.

"Okay!" Yun Tianyu nodded, took out the rusty copper piece and placed it in front of the mysterious butterfly Emperor.

"Buzzing buzzing!" The level has been increased, and the number of green silks released by the Mysterious Butterfly Emperor has more. A large number of green silks directly wrap the rusted copper pieces, constantly breaking the ban in the rusted copper pieces.

After about three hours, the ban in the rusted copper sheet gradually disappeared, and the rust on the surface of the copper sheet seemed to come alive, and the soul light kept flashing, slowly forming a mysterious mantra on the surface of the copper sheet.
Chapter completed!
