"Crystal Soul Senior?"

Sensing that it was the Crystal Soul Tower that was helping him, Hao Yu naturally fully cooperated, giving the pyramid-shaped mark on his arm and sending a thick internal breath to support the Crystal Soul Tower to deal with the strange remnants that invaded his mind.

A dazzling white light bloomed in Hao Yu's mind, under the illumination of this heroic light, the originally elusive strange remnant soul finally appeared in its original form, a gray and black air current, shuttling back and forth in Hao Yu's soul sea, wanting to break through the light of the crystal soul tower, but let it rush left and right, the seemingly invisible heroic light, but like a solid cage, the gray and black air flow, to the restriction.

"It turns out that this kind of ghost thing is doing trouble, the ancient catastrophe of destroying the world, also because of you, I didn't expect to see such a hateful foreign object like you in this mysterious and secret realm, um? No! It's just a remnant, no wonder it's so weak, today! must be destroyed...... Hey~ Maybe you can do this, right! ”

Listening to the words of the Crystal Soul Tower sounding in his mind, although Hao Yu didn't understand it, he really felt a little red, the weak remnants in the mouth of the Crystal Soul Tower, but he didn't have anything to do, at this moment! Hao Yu felt that he was still very weak.

Here Hao Yu was still secretly sighing, and the voice of the Crystal Soul Tower in his mind sounded again, this time, the old and deep voice was shouting to him: "Young man, do you want to become stronger quickly? There is a chance now, but ...... You may also be ruined by this, becoming a demon who only knows how to kill and has no self-mind, how can you choose?"

Hao Yuzheng sighed that he was still too weak, and when he heard such words, he was stunned for a moment, but at the same time, he was also relieved, Hao Yu sensed that the strange remnant soul that invaded his mind had been completely controlled by the Crystal Soul Tower, and he couldn't make waves.

After being stunned for a while, Hao Yu's eyes gurgled and rolled, and he asked cautiously: "Why did you become a demon? Can you please tell your seniors? Could it be that my rapid growth of strength has something to do with this strange remnant soul?" What is it?"

"This thing is a thing from another world, after a great change in the world in ancient times, it appeared in our world, and the people at that time called them monsters, and after the monsters were destroyed, the remaining demonic energy is the gray and black qi you see now. According to the conclusions reached by the ancient supreme powerhouses after research, the demonic energy is at least one degree higher than the strange energy between heaven and earth in our world, and it is an amazing energy, you can imagine it as the difference between the sub-king level and the king level, but the energy of the demonic qi is difficult to master, it can affect the mind of living beings, making living beings become mindless killing machines. What the Crystal Soul wants is to inject this demonic energy into your body to help you improve quickly, provided that you can withstand its influence, of course. Soul Refining Ding preemptively answered Hao Yu.

Listening to it, Hao Yu was really shocked, his mouth slowly opened, and he didn't close it for a long time: "Monster? Or is it from another world? This is too bizarre, isn't it? This gas that invaded my mind is demonic energy? Do you know that it can affect the minds of living beings, could it be that the battle to destroy the world in ancient times was because of the influence of monsters?"

"Clever! The young man is good, I don't need to add a little more, I can figure it out for myself, uh-huh~ good! "Soul refining Ding praised Hao Yu and said.

Knowing that the ancient war that led to the complete decline of Gu Wu was because of this kind of thing called demonic energy, Hao Yu didn't dare to accept the suggestion of the Crystal Soul Tower easily, but he thought about it, he just needed to become strong quickly, so after hesitating again and again, Hao Yu took a deep breath, suppressed the apprehension in his heart, and agreed to the suggestion of the Crystal Soul Tower: "Come on! I'm going to trouble the seniors, if I really become demonic and lose my mind by then, please ask the two seniors to ...... Strike in time and kill me. ”

After saying these words, Hao Yu suddenly felt that his nervousness was gone, but his heart was refreshed, he exhaled, crossed his legs, a smile flashed on his face, and then slowly closed his eyes.

"If you feel unbearable, just tell me, it's really uncomfortable, you can try to run the exercises, condense the powerful energy in the dantian first, and then find a way to refine it later. ”

As soon as the words fell, the Crystal Soul Tower took action. Hao Yu only felt empty in his mind, the heroic light emitted by the Crystal Soul Tower, with the gray and black air mass it sealed, rushed out of Hao Yu's mind, knowing that at this time, Hao Yu could really see that this so-called demonic qi was about the size of a few feet, although it wanted to continue to expand, but it was limited by the heroic light emitted by the Crystal Soul Tower.

In the gray and black air mass, Hao Yu sensed the energy that frightened him, and at this time, he realized how naïve and ridiculous his previous idea of trying to solve it with his own ability was.

"Is this the demonic energy? No wonder the ancient powerhouses all thought that its existence was a higher level of energy than the strange energy that was free from this heaven and earth, and the monster that had such terrifying energy at the beginning really didn't know how it was destroyed by the ancient ancestors. While Hao Yu was thinking like this, he did not forget to inject energy into the mark on his arm.

"Let it go...... Leave me alone, I don't want your shell, I don't want it, ah...... Please spare ...... I ......"

Under the action of the glorious light of the Crystal Soul Tower, a little bit of black gas was stripped out of the gray and black gas, and the screams followed, when Hao Yu sensed it, he was surprised to see that from the gray and black air mass, strange and terrifying faces emerged, there were human beings, and there were also alien creatures, faces emerged, and finally gathered into a face of a bull-headed monster, Hao Yu's heart suddenly jumped suddenly, he remembered the pile of white bones he saw near the place where Hui Tong picked up the treasure axe, the white bone skull at that time, isn't it exactly shaped like a bull's head？

"No! Could it be that this bull-headed monster is a monster, and that axe is its weapon, and now that Huitong is holding its weapon, isn......'t it very dangerous?"

Hao Yu's face changed greatly, and he thought about getting up immediately to remind Guo Huitong, and at this time, the voice of the Soul Refining Ding sounded in his mind: "Boy, you can't move at the critical moment, sit down." ”

"But...... But Hui Tong, that axe is the monster's thing, she carries that axe, and now it's very dangerous. Although he was suppressed by the power of the Soul Refining Ding and did not get up, Hao Yu still shouted out anxiously.

"Don't worry, the moment this demonic qi invades your body, the axe will rot, and it will have been left in the forest by the little girl a long time ago. ”

In the voice of the Soul Refining Ding, there was a bit of crying and laughing, and then, Hao Yu felt a lightness on his body, and the Soul Refining Ding relaxed his suppression of him. Knowing that Guo Huitong was not in danger, Hao Yu also calmed down and sat there quietly, waiting for the Crystal Soul Tower to send him the energy of demonic energy.
