A.D. 2116.

Since a nuclear war in 2066 without warning, many countries have disappeared from the world map. The original Arctic Circle has almost doubled, and most of Russia has become an ice sheet, part of what is now the polar ice sheet.

The Earth's climate has changed drastically. What used to be four distinct seasons of spring, summer, autumn and winter has now become a very irregular summer and winter.

Sometimes it's five months in the summer, seven months in the winter, eight or nine months in the winter, and four or five months in the summer. Perhaps, the only rule that is still a regular rule is that summers seem to be shorter than winters all the time. Fortunately, the damage to the atmosphere is not very serious, otherwise the extreme temperature difference between day and night may have reduced the post-war earth to only 300 million people, and there will be fewer humans.

This ice age-like cooling of the planet as a whole has gradually begun.

Historical name: Ice Sheet Century.

Earth's increasingly scarce resources have become a source of war and competition among the surviving powers. The surviving humans call this era the Last Night.

But now the biggest threat is not any country on the earth, I don't know when, extraterrestrial creatures have descended on the earth, and the threat of aliens is especially greater than that of the earthlings themselves. The competition for energy depends on survival, and it seems that even aliens are not exempt.

Human genes also mutated due to the needs of the environment, and at a certain point in time, the space-time where Hua Feng was located was suddenly extremely unstable, because the space-time collapse from another plane caused the two spaces to merge, which in turn triggered genetic mutations between humans and other species on the earth. The power thus brought to human beings is already comparable to the martial arts masters in the novel. Because, a special energy that can be controlled and cultivated by humans has appeared, and people call this thing Yuanqi.

The level of vitality directly determines a person's lifespan and combat effectiveness, and an era in which vitality can be cultivated is opened;

According to the World Association of Monks, the Vitality level is divided into 100 levels. Level 5 is a small stage. Level 20 is a major stage, and each major stage is divided into: beginner, intermediate, advanced, and top.

They are:

1~20 yuan human level. Equivalent to the strength of ordinary special forces.

21~40 Yuan King level. It is equivalent to between an ordinary master and a peerless master, and his cultivation is roughly equivalent to that of Wudang Grandmaster Zhang Sanfeng back then, with an average life span of about two hundred years.

41~60 Yuan Emperor level. The average life expectancy of the strong at this stage can theoretically reach more than 500 years. You can travel thousands of kilometers in an instant, and take the enemy's head among the ten thousand armies.

61~80 Yuan Emperor level. There are very few strong people who have reached the Yuan Emperor level, the average life expectancy is unknown, and they have enough energy to move mountains and reclaim the sea, and coercion alone is enough to kill people.

81~100 yuan holy level. The existence of the legend, so far, the World Cultivator Association can only rely on theoretical guesses, and the existence of this level is enough to not enter the six realms of reincarnation, not to fall into the hell of the nose, and to live forever. Legend has it that there are higher powerhouses above this, but they are more mysterious and difficult to find, and if you cultivate to the level above the Yuan Saint level, you can be truly immortal and immortal.

The balance of time and space has been broken, and countless hidden mystical realms have reappeared in the world. The fairy world, the demon world, the underworld, the Buddha world, the demon world, the human world. The immortals, demons, and gods in these six realms are ready to move.

When those characters who exist in the Six Realms in myths and legends appear alive in the world one after another. Human beings have found that the world itself is not lonely, and no one can be immune to the chaotic times.

Many unborn masters united to form the World Cultivators Association, and many people sacrificed their lives for the stability of the new fusion time and space, and some even fell since then. This includes 78 powerhouses of 70 to 80 Yuan Emperor cultivation and 156 Yuan Emperor Peak and Yuan Emperor Great Perfection cultivators, whose contributions will not be forgotten in human history, they could have done nothing. It was the twilight before the end of the night, and because of their efforts, the coming of the end night was postponed for fifty-five years.

Gods and demons descend into the world, and the six realms will fall. All the surviving humans had to desperately improve themselves, and in order to protect the people who loved them and those they loved, countless people used their flesh and blood against the blades of the alien race.

At this time, a soldier named Hua Feng suddenly found that he could change the impending destruction of gods and demons. In order not to let the nightmare come true, in order to prevent the collapse of time and space again, he had to embark on the path of cultivation, and embarked on the road of becoming a god and canonizing with a special physique with the balance of yin and yang and the five elements!
