When I first heard about the idea that crystals could be used as a new type of energy, I took it for granted, but when I thought about it, I had a terrible feeling.

Cheng Jiayi said, her body couldn't help but feel excited. "Crystals are also consumables in our bodies, and at first they ate the nutrients of our bodies, and now we dare not eat mutated foods."

Du Yiyi studied his hand and said, "We also eat mutated food now, and we also absorb crystals...... But what I use is definitely not physical strength, it is definitely crystalline.

Could it be that I'm consuming the energy of the crystals, and I can use up the crystals? Consumed into ashes? ”

"Impossible." Cheng Jiayi hesitated, "You remember, I used to absorb crystals every time I finished a battle, but now I don't need to." ”

"Yes, those who didn't replenish the crystals in time were sucked dry by the crystals." Du Yi nodded.

"That......" Cheng Jiayi "that" for a while, and nothing came out.

"I'm going to do it from the beginning. We absorb the energy of the crystals and replenish them into the crystals in our body. In the initial stage when the crystals are red, every time we use the energy of the crystals, we must replenish them in time, otherwise the crystals will extract nutrients from our body and suck us dry. "Du Yiyi.

Cheng Jiayi nodded.

"Then we advanced, we can absorb the discolored crystals, and judging by the color of the crystals in the bodies of the people we killed, the crystals in the two of us in our heads now must also be in a state of discoloration.

In this state, after using the power of the crystal, there is no need to replenish it immediately, and the crystal does not absorb the nutrients of our body. That said, the color-changing crystals store enough energy for us to splurge. ”

Cheng Jiayi nodded again.

"So, how far do we squander before the crystals stop? Will the crystals also degenerate from the discoloration stage to red? "Du Yiyi.

"I don't think so." Cheng Jiayi said, "We absorb color-changing crystals, and the crystals look like ...... Hey, we all folded our hands, and we didn't see the crystals change color. ”

Cheng Jiayi was a little annoyed, she didn't even notice, and now that they didn't have a color-changing crystal in their hands, they couldn't test it if they wanted to.

"We can experiment when we have crystals." Du Yiyi comforted, "But I don't think it's possible to change color." It should have been reduced to ashes. ”

"Why?" Cheng Jiayi asked.

"According to biological conventions, species can only grow, not degenerate. People can only live older and older, not younger and younger, and trees can only grow taller and taller, and there is nothing shorter and shorter. Du Yiyi explained.

Cheng Jiayi reminded: "This is the previous theory, and now we have all become the medium of new energy, and everything can be subverted." ”

"But the rules of survival of all things in the world will not change much—well, this one is doubtful for the time being." "Then, our body is passively boosted according to the improvement of the quality of the crystals.

Most mutants are passive, like you, and the more crystals you absorb, the more power you have, the more flexible your body is, the faster you are, and the faster you react.

These changes in the body are obviously in order to obtain more crystals and replenish themselves. This is also the law of survival, survival of the fittest, survival of the fittest. ”

Cheng Jiayi praised his head and said: "Yes, and what you found before, the more crystals you absorb, the more irritable and bloodthirsty people will be." ”

"Yes. There are also some, like me, who can now actively use the power of crystals. This is a branch of mutation, and it is also a normal phenomenon, because no matter which one of them, the ultimate goal is to obtain and absorb more crystals. ”

The two looked at each other, and Du Yiyi said slowly: "You say, if you really follow the law of red, orange, yellow, green, blue, and purple, what will happen once the crystals change color to purple?" ”

Both of them had changed their expressions.

"Crystals don't become a new energy source for no reason. Once it reaches purple, there are only two possibilities," Cheng Jiayi's expression became solemn, "Either the person is strong enough to become a new species, or the person becomes a crystal and falls into a box." ”

Cheng Jiayi and Du Yiyi were both frightened by their own inference, the two of them looked at each other, their bodies couldn't help but tremble, and they didn't speak again for a long time.

Maybe they're wrong, but is there really a big chance of being wrong? Crystals don't appear for no reason. And everything that happens after the emergence of crystals is driving the evolution of crystals and pushing them to absorb crystals.

In just over a month, the crystal has evolved to the second level, and at this rate, even if the time required for the crystal evolution increases, it will reach its peak in a year or two years.

The pendulum will swing. The pinnacle is followed by destruction.

"We can't absorb crystals like that." Du Yiyi said in a low voice.

"Don't absorb? If you don't absorb it, you won't be strong, and if you don't be strong, you may be the fittest. Cheng Jiayi smiled bitterly, "This is a vicious circle and an unsolvable proposition." ”

Du Yiyi leaned against the tree he had just attacked and looked up at the dark overhead.

The trees are so dense that you can barely see the stars overhead. He felt hopeless, he had never been so desperate.

They didn't comfort each other. None of them need empty comfort.

After a while, Cheng Jiayi said in a low voice, but resolutely: "No matter what, we have lived and experienced it." If these are the general trends, we can only go with the will of God.

If not, I just hope to live until the day the truth is revealed. If I can't, I worked hard and struggled, and it's not a pity. ”

How can a person live without regrets? The process of the existence of life is the process of regret. Because human desires are endless and can never be satisfied.

Du Yiyi lowered his gaze one by one, looked at Cheng Jiayi and said: "The mutation has just begun, and when I was still hesitating and fearing, you started shopping to save yourself." When I was in a daze and helpless, you started looking for crystals, then hunted wild dogs, absorbed.

I thought about it, you're just a high school student like me, you're still a girl, you used to be so well protected by your parents, but you just read a few more books and had fantasies.

From the moment the mutation happened, you were completely different from before, but if you think about it, you still have the shadow of the past, and you are alive as you imagined.

Cheng Jiayi, will you always be like this? Nothing can scare you? ”

Cheng Jiayi shook her head slowly: "How can you not be afraid?" You remember the last time you were in class, remember the day the classroom was full of blood. I was terrified that day, it was you who held me all the time. ”

Cheng Jiayi's voice was low: "All the fears were given that day. Because after leaving you, I went home alone, alone with the darkness, the disappearance of my parents, and the harm that my neighbors had done to me. When I thought I was going to be alone until I died, you came to me. ”

Cheng Jiayi closed her eyes, "From then on, I am not alone. One person has experienced it, two people, will they still be afraid? ”
