On March 13, 2020, a star with a diameter of more than 3,000 kilometers roared from the depths of the sea of stars and fell towards the earth. Just as humanity was crying out for the end of the world, this huge star entered the Earth's atmosphere, causing space to distort, and then disappeared.

The end of mankind has not come, but the earth is also undergoing abnormal changes, the volume is expanding, the landform is changing, the sea is rising to the island and the land, and the mulberry fields are turning into the sea. The vitality of heaven and earth has returned, the physical fitness of human beings is improving, and the unsightly martial arts cultivation that has long been suppressed by science and technology has begun to quietly rise.

In 2075 AD, the Chinese took the lead in discovering ancient ruins in the mutated Shennongjia area, found a large number of martial arts classics, the strength of the warriors greatly increased, and the practice was thousands of miles away, and then all countries have vigorously developed the mutation area, excavated ancient ruins and mausoleums, and all gained a lot.

In 2113 AD, Ling Xudu, the strongest man in China, discovered a wormhole portal in the newly emerging Taishan Forbidden Area after the expansion of the earth, connecting a new planet of life. He was named after the first Chinese dynasty and was Xia Xing.

Xia Xing is not only habitable, but also the vitality of heaven and earth is better than that of the earth, and human beings are shaken by it. In order to carry out interstellar migration in a more stable and orderly manner, reduce internal friction, and guard against possible alien enemies, the countries of the earth have abandoned their prejudices and established the Earth Council to lead mankind in a unified manner.

In 2118 AD, Ling Xudu was appointed as the marshal of the Earth Army because of his martial arts cultivation, ranking first in the world, and commanding the first army composed of all warriors to enter Xia Xing, clear Xia Xing's fierce beasts and fierce birds, and open up the first immigration area.

In 2230 AD, the number of wormholes found in the major forbidden areas and mutation areas of the earth reached 100, of which 76 led to the living planet, 55 were suitable for human survival, and 21 were large and ferocious creatures, and troops needed to be sent to guard the passage to prevent the other party from counterattacking the earth. Most of the remaining thirty-four planets are dead and desolate, but there are also some special minerals that are of great benefit to cultivation.

In 2284 AD, Ling Xudu, who had long since retired and disappeared for decades, survived the thunder tribulation in front of the world and achieved the myth of heaven and man. After that, Ling Xudu flew away from the earth, cruised the sea of stars, and discovered wormholes in Mars, Pluto and other places one after another, making great contributions to the further expansion of human beings.

In 2305 AD, Ling Xudu sorted out and summarized the different martial arts cultivation methods on the earth, smelted them into one, institutionalized them, and standardized them, forming a ten-order martial arts system, making human beings more systematic and more convenient to practice martial arts. Since then, human martial arts have ushered in an unprecedented development, and strong ones have emerged one after another.

Ten years later, the Earth Council felt the great contribution of Ling Xudu, and positioned 2305 AD, the year when the ten-order martial arts system was formed, as the first year of the martial arts calendar, and revered Ling Xudu as a martial god.

In the 135th year of the martial arts calendar, mankind discovered a new intelligent life spirit race for the first time. The spirit race is a plant life, good at mind control, the initial touch, human beings suffered a lot of losses, many immigrant planets were attacked.

In the 140 years of the martial arts calendar, feeling the unstable situation of mankind, the martial god Ling Xudu joined hands with many martial arts powerhouses to create Kunlun Academy in Kunlun Mountain, teaching martial arts secrets and quickly cultivating human powerhouses. At this point, humanity began to rise up and counterattack.

In the 256th year of the martial arts calendar, after it was confirmed that neither side could conquer the other, the hundred-year-long war between the human and spiritual races came to an end, and a peace agreement was reached to live in harmony and jointly develop the galaxy.

In the 1000th year of the martial arts calendar, a baby was born on the summer star, looking at the world with joyful eyes.
