Evolution, in general, refers to the gradual development and change of organisms from simple to complex, from low to high, and from few to many species.

However, in nature, organisms are often not more advanced and powerful, nor do they always want to evolve in complex directions.

On the contrary, most of the time the evolution of organisms, or the change of themselves, is only to adapt to the changes in the environment, in order to survive better, not to develop in a higher direction.

But once this state of affairs reaches the level of intelligent life, it is immediately a different picture.

Because once the intelligence is high enough, the living body will inevitably produce all kinds of desires, coupled with the emergence of civilization and the development of productive forces, and finally without exception, different classes will be divided between the same species.

Some people may think that after human beings entered the modern society, they have basically eliminated classes.

But in reality, class has always existed, but in a different way.

For example, in the 16th and 19th centuries, the European upper class revered white as a noble color, and in order to make their complexion look pale, they did not hesitate to wear the sun all day long, and rubbed their faces with heavy metals and even arsenic, just to distinguish themselves from the untouchables at the bottom.

After all, at that time, anyone who was engaged in manual labor basically had to endure the wind and sun every day, so the skin would inevitably become dark and rough.

In the 21st century, the aesthetics of the upper class suddenly changed from "whitening" to "tanning", especially white women with a little money, who wanted to do more sunbathing to make their complexion look slightly darker.

As for the reason is very simple, as more and more people work indoors, "whitening" can no longer allow the upper class to distinguish itself from those at the bottom of the income group from the outside, so "tanning", which requires a lot of time and money to achieve, has naturally become a replacement.

In addition, expensive food, clothing, shoes, cars, houses, private clubs with a membership system, and one secret circle after another, are all the yardsticks used by modern society to distinguish classes.

In order to improve their rank, intelligent beings will do everything they can, some races will desperately improve their intelligence to make themselves smarter, and some races will improve their physical fitness across the board to gain recognition as stronger than their peers.

In short, in this process, whether it is to improve intelligence or physical fitness, it is essentially a slow evolution.

But the problem is that this slow evolution obviously can't satisfy Zhang Cheng, so he makes a dangerous and crazy decision, which is to fuse the genes of higher-level life beings and achieve the goal of speeding up the evolution by devouring each other.

In the beginning, this plan went very smoothly, whether it was replacing his brain cells with the enhancement of the Mind Flayer's brain cells, or later devouring the body of the Divine Dragon, there was no big trouble.

But the problem is that now all his good luck seems to have run out.

The Titan essence that remained within Sargeras's abandoned body was simply more aggressive than the genes of any creature he had ever encountered before, and even the divinity was constantly being assimilated.

If nothing else, in an hour or two at most, he will become a small dark titan, a puppet with no subjective consciousness and no thinking, and the whole person is immersed in killing, destruction and destruction.

"Fight it up! I must put the dismembered Sargeras together! Then build a complete seal in the body, at least protect the brain and the rest of it, and never let the whole body be assimilated......"

Zhang Cheng, who had long since lost his human form, was now like a puddle of rotten flesh without bones, constantly wriggling and building protection with his shattered body, blocking the eroded Titan essence in the left half of his body.

Obviously, these unknown metals were originally made by the Titans to prevent their cores from being exposed, so they could naturally defend against these unknown light spots.

When the central axis of the entire body was completely split in two by a gray-brown metal compartment, he struggled to spit out the excess and restore the right half of his body to its original shape.

At this moment, he was no longer the human who was less than two meters tall, but a giant who was more than a hundred meters tall, half of his body had been completely metallized, and the other half of his body remained in physical form.

Feeling the endless evil energy and power in his body, Zhang Cheng couldn't help but sigh with a wry smile: "Is this the power of a very small part of the Dark Titan? Unbelievable! It almost killed me!"

"Master, how are you feeling now?" there was a hint of concern in the Supreme Authority's tone.

"Well, strictly speaking, I've gone from being the master of my body to being the controller. To put it simply, I can only control the physical part, and the titan part can control at most, but I can't transform into form. In addition, in terms of energy level, this body has completely surpassed the limits of mortal things, and I can now unleash earth-destroying spells even if I hook my fingers. Zhang Cheng raised his left hand and violently released a green fire of evil energy.

Compared to ordinary evil fire, the energy it contained was simply indescribable, and a large hole hundreds of meters deep was missing in the wall with a casual throw.

"Wow! This destructive power is simply unmatched!With all due respect, perhaps you may consider giving up the energy of other attributes and allowing yourself to completely merge with the evil energy. In my opinion, there is no energy that can match the power of evil energy. The Supreme Authority exclaimed, and then gave a suggestion.

Zhang Cheng shook his head without even thinking about it: "No! No! Evil energy is an extreme energy! Maybe the destructive power is very good, but it also has its shortcomings. Don't forget, my goal is to transcend, not to destroy. ”

"So what do we do now? You're like this, I'm afraid you won't be able to go back for the time being. ”

"Why should I go back? Don't you think we should take advantage of our current state to go to Argus, one of the Burning Legion's lairs?"

"To Argus?!" the Supreme Authority was visibly taken aback.

"That's right! join the Legion and gain more forbidden knowledge, especially about Titans. Don't forget, there's a newborn Titan there. Perhaps, I can do some little experiments on him......"

Just as Zhang Cheng was speaking, a deafening roar suddenly erupted in the tunnel leading to the outside world, followed by the sound of fighting and shouting to kill.

"It seems that there are guests coming, what are you going to do with them? There was a hint of schadenfreude in the tone of the Supreme Authority.
