The second-order evolution potion flowed down the Obsidian's high head. As soon as the potion touched the obsidian, it began to work, and the sliding blue streamer began to glow on the surface of the Obsidian's back armor.

The streamer rose from the abdomen and continued to gather around the location of the animal nucleus in the Obsidian's head. The Obsidian's head looked painful, but Zhang Mu couldn't help it. This was the Obsidian's own evolution. Others couldn't or dared not intervene at all, so they had to quietly watch the development of things.

Zhang Mu of later generations did not have his own mutant beast, and when other mutant beasts evolved, they generally chose a quiet place to complete the advanced process quietly. Because the mutant beast is the most vulnerable moment in the advanced stage. It is not only unable to resist the enemy, but also likely to stop the advanced stage because of a little disturbance from the outside world.

So, in this case, the lighter mutant just lost a chance to go to a higher level. When it is serious, it is likely to lose energy and destroy the animal nucleus in its brain. Once the animal nucleus is destroyed, the mutant animal will completely disappear in the world.

Although Zhang Mu seems careless, he has already asked Wang Liang to inform his subordinates that no one should come near the courtyard to disturb him before Zhang Mu comes out.

This is just the least. How could Zhang Mu decide to put all his safety in the hands of others? He had already made second-hand preparations. He secretly released the blood vine lotus and let it sneak into the ground. The huge vine network has firmly surrounded the whole yard at this moment.

Because there was no chance to observe the advanced process of the mutant beast closely, Zhang Mu was not sure. After all, he had no experience. The only basic cognition was to listen to it casually.

But at this time, Zhang Mu's heart surged up with anxiety.

Zhang Mu's sixth sense has always been very accurate. Sure enough, only a second later, his spiritual link with Obsidian became unstable. He felt the pain of obsidian from time to time.

Obsidian is in a difficult situation now?

Zhang Mu continued to focus on the body of the obsidian. He was surprised to find a detail that he had just ignored. Although the abdomen of the Obsidian continued to impact energy on its brain because of the existence of second-order evolutionary medicine, the Obsidian's uneasy mood became more and more serious.

The key is that I don't know why. Zhang Mu has no way to start now. This matter is more complicated.

Seeing the Obsidian's body trembling, the wolf dog's eyes raised an inexplicable fear, bared his teeth in the direction of the obsidian and kept yelling. Yuanrui wanted to help the Obsidian alleviate its pain with her ability, and was directly stopped by Zhang Mu.

In Yuanrui's puzzled eyes, Zhang Mu solemnly explained, "now Xiaohei is not injured. Its situation can't be solved by pouring life ability, because there are too many uncertainties in this evolution. Any energy that doesn't fit Xiaohei's internal attributes may destroy its internal balance.

Xiaohei's attribute is not a life attribute, so even for the healing life energy, it is very likely to destroy its advanced process, resulting in advanced failure, or even worse, Xiaohei may die. "

Hearing Zhang Mu's words, Yuan Rui hurriedly put away her hands and covered her mouth. She looked incredulous. Is Xiaohei's situation now critical?

Zhang Mu also regretted his arrogance. There were still too many places he didn't know. He thought the advanced level of the mutant beast wouldn't be so complicated. Unexpectedly, he still did.

Just when Zhang Mu had a headache, the trembling frequency of obsidian's body had increased, and he looked like he was about to lose his hold.

Suddenly, the Obsidian insect's intermittent voice came from Zhang Mu's heart, "give me the beast core... Wind..."

After that, there was no sound from the obsidian, as if he had completely broken contact with Zhang Mu.

Hearing the call of obsidian, Zhang Mu immediately excited his soul.

Yes, it's the same animal core! What Xiaohei needs now is it!

The amount of second-order evolutionary medicine is absolutely sufficient, so it has been continuously impacting the animal nucleus in the Obsidian brain. However, the proportion of animal nuclei with other attributes taken by Obsidian before is too large, resulting in its own animal nucleus refining purity not reaching an advanced index, so it can't carry it now.

These thoughts just flashed through Zhang Mu's mind. He instantly took out the bag containing animal core previously hidden in the era merchant ring.

Fortunately, Zhang Mu had the habit of classification before, which was developed by later generations. After all, it would be too troublesome to distinguish the types of animal nuclei at trading time.

He instantly picked out the one with wind attribute mark from a pile of small bags, and without blinking, he wanted to pour it into the Obsidian's mouth.

However, just now because of too much pain, obsidian has long closed its big mouth tightly, and now obsidian is fully resistant to the erosion of second-order evolutionary medicine, and can't have the energy to control its body.

Although Zhang Mu's strength has doubled his adult strength, he is still worthless in front of the bite force of obsidian. He wasted his strength to pry open a small crack in the big mouth of obsidian, and forcibly bounced a smallest wind attribute animal core into it.

Sure enough, when the animal core was just bounced into the Obsidian's stomach, it reacted. Its trembling body was about to spasm. It absorbed the energy of the same attribute and helped it share a lot of washing from the medicine. It was relieved and relaxed.

Zhang Mu was also anxious. He took the opportunity to shout at the Obsidian's head, "fool, open your mouth and bite so tightly. Why? I can't open it."

With the help of this foreign animal core, the Obsidian seemed to hear Zhang Mu's voice and restore a little control over his body. His just closed mouth was lifted up, and a small hole appeared in an instant, but he soon couldn't hold on to the meaning of putting it down. It seems that the energy of the animal core just now will soon be exhausted.

Zhang Mu saw that he didn't dare to delay. At that time, he was a step slower. The fool said he couldn't shut his mouth again. Zhang Mu quickly poured all the wind attribute animal nuclei in his bag into the small hole, spilled a lot, and was quickly picked up by Zhang Mu. He didn't have time to wipe the soil on it and stuffed it in again.

When all the animal nuclei were put into the Obsidian's mouth, Zhang Mu lifted them up again. These animal nuclei all fell into the Obsidian's stomach.

They neutralize the energy of the Obsidian's abdomen and the second-order evolutionary potion. In this way, the impact on the Obsidian's own animal nucleus becomes smaller and smaller, and then it becomes a simple absorption of this gentle energy.

When the blue light frequency on Obsidian gradually softened, Zhang Mu was happy and knew that things were almost done. He was a little excited.

Roar!

The sudden roar directly shocked Zhang muyuanrui, who stayed beside the initiator of obsidian, to stay in place.

Just when Zhang Mu wanted to curse, obsidian kept spitting black silk thread out of his mouth, which scared Zhang Mu to pull Yuanrui back.

In just ten seconds, a huge black cocoon appeared in the center of Zhang Mu's courtyard. The black silk thread lingered around the whole cocoon with a mysterious smell.

Zhang Mu swallowed his saliva in a daze. He couldn't even keep his usual indifference. "He will cocoon. I began to doubt whether the real father of this goods is an obsidian. Is it an old silkworm next door?"
