In an icy cave

When Leo exchanged bloodlines, Cecil, who had stuck his whole body on the ice, was stimulated by the frost energy that Leo forced out of his body, and then Cecil, who woke up from the comfortable state of absorbing energy, was a little overwhelmed after realizing what he had just done, and then with a panicked face, he jumped back violently, and after leaving Leo some distance, he looked at Leo with a cautious gaze.

"Whew, it's okay!" Looking at Leo's closed eyes, Cecil was glad that his actions had not been noticed by Leo, but he saw Leo's distorted face.

"He seems to be in pain!"

Sersi guessed, and then became worried about the creature he had picked up, which could listen to him and provide him with frost energy.

"Click!"

At this moment, the ice cube cracked a crack, and then a large amount of blood-colored frost energy slowly seeped out along the gap, and then dripped down the crack along the ice surface like water, and then condensed into blood-colored ice balls containing frost energy the size of half a thumb.

"What's that!?"

Seeing this scene, Cecil's mind was full of question marks, but when she saw those blood-colored ice balls, her breath was stagnant, and her eyes were a little confused, because she felt the fatal attraction of the blood-colored ice balls to her.

Without any resistance, under the allure of the blood-colored ice balls, Cecil walked to the blood-colored ice balls, then squatted down, picked one up, and put it in his mouth under the instinctive drive, and then bit it down hard.

"Quack!"

With a crisp sound, the seemingly hard but fragile ice ball, like a bean, was bitten apart by Cecil, and then the frost energy mixed with a trace of blood spread from Cecil's mouth to her whole body, increasing the frost energy in her body by a small margin.

"It's delicious!"

Cecil's eyes lit up, and he couldn't wait to pick one up again, put it in his mouth, and then a pair of scarlet eyes narrowed into a beautiful crescent.

"Quack, quack......"

One, two, three......

When Cecil ate more than a dozen of them, feeling that his body was full of frost power, and he couldn't digest it anymore, he finally stopped, looked at the nearly 100 blood-colored ice balls on the ground, and after licking his pale blue lips, he picked up those blood-colored ice balls one by one, put them in the shell of the blue peel fruit she had just eaten, and then carefully hid them in the corner of the cave.

Hiding his things, Sersi slowly walked over to the crack in the ice that had sealed Leo.

"Well, he's less miserable!"

Cecil was overjoyed to see Leo's calm face, and strangely enough, she found that she seemed to have a different feeling for the frozen creature, a feeling called dependence and irresistibility.

"What's going on?"

Cecil was a little puzzled by this, but after thinking about it for a while and not figuring it out, she shook her head, left it behind, and then lay directly on the ice floor in the cave of the icy mountain, and fell asleep in order to digest the frost power in her body.

As the bloodline was exchanged, the painful sensation that came from Leo's body was slowly becoming lighter, and then an energy that belonged to the bloodline began to slowly appear in his body.

Then, under the effect of the energy obtained from this exchanged bloodline and the system, the final cleansing of the frost energy remaining in the body is being carried out.

Then Leo felt that during this final clean-up, some of his blood was expelled from his body with the frost energy.

Leo didn't feel a pity for this, because this part of the blood was the blood that was completely fused with the power of frost.

But Leo didn't know that when this part of the blood was discharged, the newly acquired demonic power that participated in the process also fused into that part of the blood. When the frost energy mixed with demonic power and his blood was excreted from the body, it condensed into blood-colored ice balls, which were then eaten by Cecil.

And this is the reason why Cecil will have a sense of dependence and irresistibility towards Leo, after all, there is a demonic power in it......

After Cecil fell asleep, after Leo expelled the frost power from his body, the ice box on Leo's right hand finally stopped releasing the frost power because he lost the summoning of the frost power in Leo's body.

Without external pressure, Leo's bloodline was in the process of final fusion with him, and then the mutation mentioned by the system finally happened...... The mutant power within him is resisting the bloodline that he is fusing with!

Mutant power has always been a sign of mutants, and the reason why mutants have all kinds of incredible powers is because of the X gene in their body, and the X gene is a sign that distinguishes mutants from ordinary people, and it can be said that the X gene is the racial origin of mutants.

Although the mutant power in Leo's body is obtained by the system lottery system, it is undeniable that the genes in Leo's body have undergone some changes, which means that Leo, who uses various variant powers, has been defaulted by the system to having this bloodline.

So far, the Slasher has been systematically 'manufactured' based on Leo's own soul, so it has not clashed with its mutant abilities.

And the abilities on his body have always belonged to the mutant abilities, whether it is teleportation, telekinesis, thunder and lightning mastery and rapid healing, this will not conflict with a series of abilities that belong to the mutant ability, because they themselves are derived from the power of the X gene.

But when he exchanges another bloodline, the power brought by that exchanged bloodline will conflict with the mutant power in his current body!

Feeling the pain caused by the clash of two forces in his body, Leo frowned, but at this moment, Leo felt the mysterious energy belonging to the system that appeared when he exchanged bloodlines before.

"Why did the power of the system appear again?"

Leo was stunned for a moment, thought for a while, and then understood.

For the system, since you have exchanged the bloodline, then you will definitely be guaranteed to exchange it successfully, so the frost power that did not belong to Leo before and obviously hindered the fusion of the bloodline will be cleared out by the system.

And now, because of the resistance of Leo's exchange bloodline under the resistance of the mutant power, he has not been fused with him for a long time, and if there is no fusion, it will not be considered a successful exchange for the system, so this situation of not being successful in exchange has once again attracted the intervention of the system.

Both powers belong to Leo himself, and the system can't be cleaned up like the frost power before it is cleaned, and in the face of such a situation, there is only one way, and that is bloodline fusion, under the power of the system, mandatory fusion!
