Three days later, Yun Tianyu and the others said goodbye to Nan Hongpeng, Taishi Mingyue, Pleiades and others and left the Star Palace, and took a flywheel to the vicinity of the Tianlei Mountain Range.

And now there are three months left before the competition in the Four Great Dao Academy, Ren Yunqi, who has high hopes for Yun Tianyu and opened the door of convenience for him, learned that Yun Tianyu had not returned for a long time, and he had not cultivated in the Xiaoqiankun Realm for a day, so he was furious and kept sending people to look for Yun Tianyu.

When Yun Tianyu and the three of them appeared on the edge of the Tianlei Mountain Range after the transfer, the medicine fire that had already arrived learned the news of the arrival of Yun Tianyu and the three of them through the transmission bead, and immediately appeared and saluted respectfully.

Ying Cangxin was taken aback when he saw the medicinal fire appear, and respectfully saluted Yun Tianyu, after all, it was absolutely impossible to subdue a seventh-level Dao Venerable master by ordinary means, and the medicinal fire was still a powerful pharmacist. However, as a smart person, he didn't ask Yun Tianyu how he did it, but he was more convinced of Yun Tianyu.

"Yaohuo, have you recovered from your injuries?" Seeing Yaohuo walking out of the lush Tianlei Mountain Range, Yun Tianyu asked softly.

"Thank you for your concern, my injury is no longer serious. ”

"Childe, this is the Huitian Pill you want, I used the materials you gave me to refine a total of ten Huitian Pills. "Yao Huo took out ten black pills from the Qiankun Ring and handed them to Yun Tianyu.

"Okay!" Yun Tianyu nodded slightly, took the ten Huitian Pills and put them into the Lei Ze ring.

"Master, although this time the Heavenly Pill can instantly restore the power of the Yuan Infant consumed by the Dao Saint Master, but it can only take one within a day, if you take it continuously, not only can you not recover the power of the Yuan Infant consumed, but also will have great damage to the body, so Childe must be cautious. After Yun Tianyu took away the ten Hui Tian Pills, Yao Huo told him about the medicinal effect of the Hui Tian Pill.

"Well! I remember. Okay, you can follow me to the black forest in the Tianlei Mountain Range, and you will be an old friend. Yun Tianyu nodded lightly, and took two seventh-level Dao Venerable peak masters, one large and third-level Dao Venerable masters, entered the Heavenly Thunder Mountain Range, and flew towards the black forest deep in the Tianlei Mountain Range with his memory.

About an hour later, the four of Yun Tianyu, who were flying rapidly all the way, appeared outside the black forest and walked into the ghostly and terrifying black forest.

"Chatter!" Yun Tianyu and the four of them broke in, immediately alarming a large number of yin spirits in the black forest, and one by one the yin spirits let out a terrible ghost cry sound, desperately attacking Yun Tianyu and the four of them.

However, under the protection of the Three Great Dao Venerable masters, the Yin Spirits that attacked one by one were crushed by the mutant infant power released by them before they could get close to them, and dissipated in the black forest.

"Don't hide, come out quickly, I've killed your brother to avenge you. Stepping on the fallen branches and leaves to the grave deep in the black forest, Yun Tianyu took out a human head from the Razor ring and threw it to the edge of the grave, and said coldly.

"Thank you for killing this beast and avenging me. Hearing Yun Tianyu's cold voice, the even older soul old man came out of the tomb, and when he saw the dead human head rolling down on the edge of the tomb, he showed a complicated expression, but he still said gratefully.

"I don't know if you have obtained the Tai'a Sword, the treasure of my Bingzong Zhenzong?" The soul old man released a wisp of soul power, and after crushing the head of the dead person, he calmed down a lot and asked.

"Why do you ask knowingly, I think I know better than me whether I have obtained the Tai'a Sword. The corners of Yun Tianyu's mouth turned up slightly, and he said unceremoniously.

"Your Excellency, don't blame, in order to survive, I used my secret method of the Martial Sect, so that my mutant baby god parasitized in the Tai'a sword and slept in the cold pool, it can be said that the mutant baby god has almost no connection with my soul, and anything that happens is not my control. The soul old man explained.

"Really?" Yun Tianyu said as the corners of his mouth turned up slightly, not believing the Soul Old Man's explanation.

"Please trust me. And I think Your Excellency has already refined the Tai'a Sword, I don't know if Your Excellency can take out the Tai'a Sword to show me, satisfy my last wish, and let me feel at ease in the reincarnation. The soul old man said in a sincere tone.

"Yes!" Although Yun Tianyu felt that the soul old man was by no means honest, but with the protection of the two seventh-level Dao Venerable peak masters, Yun Tianyu was not afraid of the soul old man's hands and feet, and with a move of his mind, he took out the best heavenly weapon Tai'a Sword that had already been refined.

When the soul old man saw the Tai'a Sword in Yun Tianyu's hand, which was covered with spell dark lines, his eyes revealed a complicated look, and his entire body suddenly turned into a soul light and burrowed into the Tai'a Sword.

"Ah, what did you do to Tai'a Sword, how could you have such a powerful spell power. "The moment the soul old man drilled into the Tai'a Sword, he immediately felt the power of the life spell that Yun Tianyu had entered inside, and let out a painful roar.

"Do you think I don't know what I want to do when I take out the Tai'a Sword? I've been fooled once, and I won't be fooled a second time. Now you'd better tell me the secrets of your Bingzong honestly, and I can let you go, or I'll let you disappear now. Yun Tianyu felt that the soul old man was attacked by the soul spell in the Tai'a Sword, and he was extremely painful, and his voice was cold and threatening.

"Even if I die, I won't tell you the secret of the Bingzong, I will let this secret disappear forever with me. In the end, the conspiracy of the parasitic Tai'a Sword was destroyed by Yun Tianyu, and the soul old man let out a crazy sound, and he wanted to explode his soul body.

"Don't say it? With that, Yun Tianyu controlled Tai'a Sword to forcibly force the weak soul old man out, and then summoned the Butterfly Emperor to control him.

Under the invasion of the powerful confusing power released by the Butterfly Emperor, the soul old man whose soul body was extremely prostrated couldn't resist at all, and before he could explode his soul body, he was controlled by the Butterfly Emperor.

"I'll ask you now, what is the biggest secret of your Bing Sect?" Yun Tianyu asked coldly.

"The biggest secret of my Bing Sect is that it can carry out a second mutation of the mutant baby god, and this secret can only be mastered by the sect masters of my Bing Sect. The soul old man, whose soul consciousness was controlled by the Butterfly Emperor, replied with some smugness.

"It was really guessed by the Great Demon King, the biggest secret of the Bing Sect can really carry out a second mutation of the mutant baby god. Yun Tianyu raised his eyebrows and said with some surprise.

And the three of them also became very interested when they heard that the Bingzong actually held the secret of the second mutation of the mutant baby god, because if the seventh-level Dao Venerable wants to break through to the first-level Dao Immortal, the most important thing is to improve the power of the mutant baby god.

This is also the reason why Daozun masters easily do not use the mutant baby god when they are in a fierce battle, because once the mutant baby god is greatly damaged, it will affect the future realm ascension.

"Now, tell me the greatest secret of the Bingzong, remember, don't hold back. Yun Tianyu ordered irresistibly.

"Yes!" The soul old man with a disillusioned gaze nodded, and said in detail: "My Soldier Sect is a secret method engraved in the sect master's token to let the mutant baby god undergo a second transformation, thus generating parasitic spirit soldiers. After the mutant baby god produces a spirit soldier, his own strength and attack power will be greatly increased. And if you encounter a threat, you can also attack by self-detonating spirit soldiers, and more importantly, the spirit soldiers self-destruct will only consume the power of the mutant baby god itself, but it will not damage him, and it only takes a few days of cultivation to recover. ”

"You can let the mutant baby god produce spirit soldiers! I think the attack on Cangxin was caused by the self-explosion of this spirit soldier. Knowing the biggest secret of the Bing Sect, Yun Tianyu said silently in his heart.

"Okay, you tell me now, how to get the method of the second mutation of the mutant baby god from this suzerain's token. Yun Tianyu's mind moved, took out the sect master token, and ordered loudly.

"If you want to know the method of the second mutant infant god from the sect master token, you must drip blood from the sect master token to recognize the master, and infiltrate the soul into it to know the cultivation method, but if you repeat the blood to recognize the sect master token in a short period of time, the sect master token of my soldier sect will be broken, and future generations will no longer be able to master the cultivation method. The old man of the soul said with a smile.

"Okay, I see, now you can wake up. Knowing the secret he wanted to know, Yun Tianyu showed a satisfied smile and summoned the Lost Butterfly Emperor, restoring the lost soul consciousness of the soul elder.

"You, what did you just do to me?" Regaining his senses, the soul old man suddenly felt that he had just lost a small memory, and immediately guessed that Yun Tianyu had done something to him, and asked loudly.

"It's nothing, I just asked you to tell me the biggest secret of the Bingzong. The corners of Yun Tianyu's mouth turned up slightly, and he said without concealment.

"What! you, except for the sect master of my Soldier Sect, outsiders who cultivate the secret method of my Soldier Sect will be punished by heaven. The soul old man roared in annoyance.

"Damnation, if Heaven really wants to condemn me, I will not be afraid. Yun Tianyu said without fear.

"Damn villain, I'm going to kill you!" The soul old man gathered the last of his strength and launched an attack on Yun Tianyu.

"True Dragon Yin!" Just as the soul old man approached Yun Tianyu, Yun Tianyu's body suddenly swelled, releasing a powerful true dragon roar, rolling and sweeping towards the soul old man, directly shattering his weak soul body and disappearing between heaven and earth.

"Alright, let's go, find a place to copy the method of generating spirit soldiers recorded in this sect master token. With a roar that shook the soul elder, Yun Tianyu quickly left with the Three Great Dao Venerable masters, and came to the outside of the thunderous Heavenly Thunder Valley with a familiar car, preparing to copy the method of recording the second mutant infant god in the sect master token here.
