The Tree of Mental Power was actually able to withstand the high temperature of melting everything, which made Duan Yun also feel a little incredible. But he didn't know that the Heaven Breaking Technique did not belong to this low-level world, so the Tree of Mental Power that it evolved naturally could not be measured from an ordinary perspective.

Seeing that the Earth Fire Spirit was restrained, Duan Yun breathed a sigh of relief. However, as for how to subdue this naughty earth fire, he was still confused.

"Big brother, let me go quickly, suffocate me. The Spirit of Earthfire cried out in pain.

"Stay in there first, I won't dare let you out. "It was not easy to take down this little guy at the risk of his life, and of course Duan Yun would not let it out easily.

"Hmph, ignore you. The Spirit of Earth Fire pouted, and lay down in a puff, and actually fell asleep on the branches of the Tree of Heart.

Seeing that the little guy had finally settled down, Duan Yun walked out of the formation according to the method given by the giant bear.

The giant bear was still waiting outside, and when he saw that Duan Yun was safe and sound, he was relieved.

"Well, that little guy is so good, we don't dare to get close to him. It's not easy for you to get out of the way. Alas, let's go first, and then come back to deal with it when we think of a way. The giant bear obviously didn't think that Duan Yun could solve the trouble of the Earth Spirit Fire, he walked quickly to Duan Yun's side and said.

"Senior, I think the trouble here should be solved. Duan Yun smiled indifferently.

"What? I heard you right?" the bear couldn't believe his ears. He hurriedly looked into the array, but only saw a ball of flames, and there was no trace of the Earth Fire Spirit in it.

"This spirit of earth fire is in my body now, and although it has not been subdued, at least it will not cause any chaos. Duan Yun scratched his head slightly shyly and said.

"Hahaha, you kid, you're such a freak. Let's go, let's have a few drinks and go to ......". Seeing that Duan Yun didn't look like he was lying, the giant bear couldn't hide the excitement in his heart, he stretched out his fan-sized bear paw, pulled Duan Yun up and walked towards his cave mansion.

The Spirit of Earth Fire can be said to be a piece of the giant bear's heart, and for the sake of his master's entrustment, he has to wander in this cold ice valley every day, insisting on his own protection. And now, this heart disease has finally been removed, which also makes the giant bear feel relieved.

Taking out the wine that has been treasured for nearly a thousand years, the two sat opposite each other.

The bear clumsily opened the jar, and the aroma overflowed. Just smelling the aroma of this wine, Duan Yun felt that his internal strength was about to move.

"This is the owner's Lanxin wine, which has been treasured for thousands of years. I am reluctant to drink it myself on weekdays, but today I will be cheaper for you kid" The giant bear poured a glass of wine and handed it to Duan Yun.

"Thank you, seniors. Duan Yun said, he couldn't help but take a sip, and suddenly his internal force seemed to be ignited, and it was running rapidly, and wisps of internal force impurities were continuously vaporized, while the remaining internal force gradually became pure.

Unexpectedly, this wine actually had such benefits, Duan Yun began to swallow it, and soon half of the jar of wine went down. The giant bear couldn't help but feel a pain in his flesh, this way of drinking is simply a tyrannical thing. However, he also saw Duan Yun's current state, so he didn't step forward to stop him.

The purification of internal force finally reached a limit, and Duan Yun also touched the threshold of the eighth-level martial guard. But he tried his best to suppress it, because there was still a time bomb sleeping in the tree of his heart. Once the breakthrough is made, there will inevitably be a change in the tree of mental strength. If the Earth Fire Spirit was freed from its shackles because of this, then Duan Yun would soon be reduced to ashes.

Sensing the problem with his body, Duan Yun hurriedly said goodbye to the giant bear, he needed to find a quiet place and find a way to solve the trouble of dropping the Earth Fire Spirit.

Leaving the Cold Ice Valley, Duan Yun found a cave with a strong aura and lived in. From time to time, he released his spiritual power into the Tree of Mental Power, observing the movements of the Earth Fire Spirit.

After such a period of adaptation, the spirit of earth fire gradually no longer rejected the restraint of the tree of mental power, on the contrary, it was quite satisfied with such a place to sleep. But how to take it for his own use, Duan Yun was still at a loss.

Finding that Duan Yun's spiritual power was probing himself, the Spirit of Earth Fire yawned, stretched, and pretended to enjoy it.

"Little guy, do you want to come out?" Duan Yun used his spiritual power to communicate with the Spirit of Earth Fire.

"Cut, it's so good here, I'm not going out, sir. The Spirit of Earthfire pursed his lips.

"It's best if you don't come out, but don't mess with me inside. Otherwise, I'll let this little tree wrap you up tighter and suffocate you. Hehe," Duan Yun grinned at the Spirit of Earth Fire.

"I don't listen, hum" Although the Spirit of Earth Fire said this, Duan Yun could still see that this little guy was obviously trembling.

"If you are obedient, I will go back and find you a fire source for you to devour, and you will destroy the environment every day......" Seeing that the threat had achieved results, Duan Yun did not forget to give this earth fire spirit a little sweetness.

"What you said is true?" Hearing that there was a benefit, the spirit of earth fire suddenly came to his senses.

"I, Duan Yun, never lie to children when I speak. Duan Yun said with some humility.

"Okay then, I'll believe you once, sir. The Spirit of Earthfire pretended to think for a long time before speaking.

"Trust me, I'm right, but what do I call you?Xiaohuo?Xiaohong?Xiaoyan?Do you see that name?" The abduction plan was successful, and Duan Yun was relieved.

"You can think of such a dirt name!" the Spirit of Earthfire scratched his head, revealing a look of disdain.

"Then you can figure it out for yourself. Duan Yun was amused by this little guy.

"Master, I'm too lazy to use my brain, just call me Xiaohuo. If it's okay, don't disturb the master's Yaxing. "The spirit of earth and fire belongs to the heartless, and he threw down this sentence and ran to the side to play.

Finally solved the problem of this time bomb, and Duan Yun started to prepare to break through.

After such a long period of accumulation, Duan Yun's internal force had already reached a limit. After a brief preparation, he calmed down and quickly activated the internal force.

Xiao Huo also seemed to know that Duan Yun was at a critical moment, he gathered the flames into his body, stared at Duan Yun with big black eyes, and didn't dare to take a breath.

"Bang" The surging internal force is surging, constantly impacting the tree of mental strength. Under this crazy impact, cracks began to appear in the trunk of the Tree of Mental Power. The small fire rolled by the branches looks like a swing, and it looks very funny.

"Roar" Duan Yun endured the severe pain and let out a roar. The whole cave shook up, and stones kept falling from the roof of the cave and smashing on him.

However, for Duan Yun, these stones were not a big threat. With a wisp of spiritual power, he probed the situation of the Tree of Mental Power. I saw that the tree of mental power was like a balloon that had been blown up, rapidly expanding.

However, at this time, Xiaohuo accidentally sneezed. With a high temperature of air, it instantly rushed towards the Tree of Mental Power.

"Ah" Duan Yun suddenly let out a miserable scream, but he didn't have time to blame Xiaohuo.

This hot air flow became the last straw that broke the tree of mental strength. A muffled sound came from the trunk of the Tree of Mental Power. Then I saw the bark on the outside peel off like debris, and as it fell off, new bark quickly grew.

The Tree of Mental Power gave Duan Yun strong strength, but it was also destined for him to endure different pains every time he broke through. At present, Duan Yun almost all has a feeling of near-death. He maintained a trace of clarity and tried his best to guide the internal force. Once the internal force is turbulent, Duan Yun's body will inevitably collapse.

Finally, the condition of the Tree of Mental Power stabilized. To Duan Yun's surprise, due to Xiao Huo's sneezing, the newly-born Tree of Mental Power actually carried the breath of fire. This also means that his internal force contains the fire element, which will undoubtedly attach a fire attribute attack to his moves.

In the process of restoration, the tree of mental strength continued to rise until it was twenty meters high. At the moment when the Heart Power Tree stopped growing, the majestic internal force fed back, rushing towards every cell in Duan Yun's body at an extremely fast speed.
