In the Western calendar of 2050, the United States of America and the European Union countries, after years of secret research, finally took a breakthrough in human genetic engineering.

In their experiments, they inadvertently found a magical substance that allows the mitochondria in cells in the human body to mutate and strengthen again, so that humans have the possibility of infinite evolution again.

This substance was eventually made into a new drug called a genetic enhancement potion.

After the injection of genetic reinforcement agents, supplemented by various special training, the human body potential can be greatly enhanced, and can be easily achieved, just like Superman in the comics, the force is infinite and the speed is amazing.

After genetic strengthening, humans with great strength have been collectively referred to as genetic warriors in Europe and the United States; according to the different combat effectiveness, they are divided into warrior apprentices, warriors, warriors, warriors, gods of war, and many other realms, and each realm is divided into several levels.

In the face of such genetic fighters, the traditional gunpowder light weapons completely lost their role, under normal circumstances hit them, can not cause much damage; as for heavy weapons, the battle will and the above level of the war will basically lose their role.

In 2065, after 15 years of successful genetic technology research, China, which has gathered the strength of the whole country, is a reluctant reverse study, and the initial technology of genetic reinforcement is very different; but it is frustrating that this technology actually enhances the success rate and effect in the human race.

After each person is injected with a genetic evolution potion, the enhanced effect will be completely different, ranging from the lowest 13% evolution to the highest record of 90%.

Most people will only get about 20% of the degree of evolution; these people, if not surprisingly, are just ordinary people who are physically stronger and physically better; of course, they have a greatly increased life expectancy and live more than a hundred years, which is completely no problem.

The higher the degree of evolution, the higher the efficiency of cultivation, and the higher the level that can eventually be achieved.

The general degree of evolution can reach more than 40%, even if it is the genius of ordinary people, can be educated by the elite education of the best national schools in various countries; if the degree of evolution exceeds 50%, it will become the goal of all large and small forces.

Other people of color, including the yellow race, have a record of only 80% of evolution, and the universal, white people in the West inject genetically strengthened drugs with higher degrees of evolution.

That is to say, the top group of masters, almost all of them are white.

For a time, God’s preference for white people was clamoring in the mainstream world; Chinese traditional culture, Chinese medicine, populism, and even living habits were seriously questioned.

It is ironic that this reverse-day genetic enhancement technology brings great benefits at the same time, it is like opening Pandora's box and releasing a huge demon.

The various animals of the world, because they were affected by the mutations of human genes; they also gradually mutated, became extremely powerful, and even high-level beasts, produced powerful intelligence, began to culling humans.

Gradually, villages, small towns, and even counties outside the big cities became no longer safe; helpless, people had to move to the surrounding big cities, relying on the huge urban defense facilities built by the big cities to resist the attacks of the beasts.

The vast mountains, rivers, and vast oceans have once again become the land of the beasts.

In the end, China left only 168 large base cities, and more than a billion Chinese crowded in these few cities, making every base city crowded and terrible.

And what caused all this, America and Europa, even with more genetic warriors, had to shrink into the fortified base cities in the face of a sea of mutated beasts, like China.

In such a dramatic change, the genetic warrior has become the most respected and highest-ranking group of people on the planet; these warriors combine traditional martial arts to create a variety of more powerful martial arts and more efficient cultivation methods.

They opened a variety of martial arts, dots, training centers, among which the most powerful batch, and even a few large countries, are very kind to them, with many privileges.

This is the worst time ever for humanity, and it is also the best.
