"Isn't it just a mouse?" Mu Bai didn't understand very much, and even Mu Yuxin was confused.

"Your experiment won't succeed!" Ding Jiao said firmly, "Even these mutant rats fed with the blood of the 'ghost rats' are the same, but they are just a group of mottled bloodlines that have been infinitely diluted, and the mutations produced are at most like this."

"You know what!" Cao Bo suddenly roared, "Maybe it was true before, but now that they have evolved, they are different!"

He looked extremely excited, pointing to these two-tailed or even three-tailed mutant rats on the ground, and his tone trembled a little:

"Before, they only had one tail, but now they have three tails, you know what that means?"

seems to be talking to himself, and seems to be showing off to everyone:

"This means that as long as you keep cultivating, it's only a matter of time before the Six Tails appear! The six tails of the ghost rat, there will always be a six-tailed one like the ghost rat."

"The ghost rat you saw was a six-tailed ghost rat?" Ding Jiao was a little surprised.

"Hahaha! Six-Tails...... That's a beautiful six-tail!" Cao Bo laughed a little maniacally, "It's going to reappear...... It's going to happen again!!" The latter sentence has an accent, a very affirmative tone.

"Big brother!!" Hong Yang suddenly exclaimed.

I saw that the mutant rat in Cao Bo's hand showed its sharp teeth and bit his palm fiercely. There is no act of gnawing, but it is sucking his blood.

"Big brother, hasn't it been tamed by you?" Hong Yang shouted in horror.

Cao Bo ignored him, and gently touched the mutant mouse in his hand, as if he was treating the person he loved the most, with deep obsession in his eyes.

"It's going to evolve! There may be some surprises along the way, but it will definitely evolve!" One of Cao Bo's eyes began to appear a black curtain, covering the whites of the eyes, but the pupils were stained with scarlet.

The two-tailed mutant rat in his hand gradually grew a third tail hook, and at the same speed, another four tail hooks grew.

"Do you think you'll succeed by taking the final step as a test subject?" When Ding Jiao saw this, she was clear.

"Big brother, isn't it better to find ordinary people to experiment?" Hong Yang was shocked.

Cao Bo's inexplicable obsession came from nowhere, and he carried out the last step of the experiment on the spot.

"Hehehe......" Cao Bo smiled weirdly, "How can ordinary people waste such a rare thing."

Except for the change in that eye, there was nothing unusual in Cao Bo's body. However, the mutant rats on the ground who had been searching for food alone raised their heads in unison to look at him.

At the same time, Qi Qi lowered his head slightly, and the tail behind him was obediently perpendicular to the ground, showing a gesture of submission.

The crowd was shocked.

"Hahaha! It worked! I succeeded!" Cao Bo laughed out loud excitedly, "Mr. Zhuo, have you seen it? I've conquered them completely!"

Zhuo Kaize frowned, that was disgust.

It's just that Cao Bo didn't notice it, he was happy: "Our cooperation can continue, I have already let you see the result, our agreement ......."

"Nope." Zhuo Kaize shook his head, "You are not qualified to cooperate with us."

"The ghost rat is a low-level species, and it is not enough for my eyes. What's more, this thing is not even as good as a ghost mouse." He was referring to the precious mutant rat in Cao Bo's hand.

"Captain, the ghost rat still has at least six tails, and your rat with mixed blood, only four tails, still wants to cooperate with us? It's wishful thinking." Dazhuang said disdainfully.

"You promised me!!" Cao Bo's low-pitched voice was filled with extreme anger.

The mutant rat in his hand also raised its head angrily, and the four tail hooks stood upright in an attacking posture.
