Brief introduction to the plot of Kaineng, an over-limit hunter

In 23 AD, in order to solve the increasingly serious population problem, human beings began to emigrate to the universe. Scientists build huge cosmic cities in annular facilities called "gravity rings". In just a hundred years, half of the human beings have lived there.

In 2458 AD, the earth and Mars gravitation ring migrated, and a war broke out in the lunar airspace for the event of rare earth expropriation on Mars. After both sides paid a painful price, Mars and the earth stopped all communication and opened a short-lived peace.

In the era of zero war, apart from the threat of Mars, space pirates composed of criminals on the moon became increasingly rampant.

more than 1 years of peace ended in 2588. When the new influenza H1Z1 broke out in the moon city-state, Mars, which had been isolated for a long time, released goodwill and sent a medical ship to the moon for humanitarian rescue. Unexpectedly, this false aid turned out to be the beginning of the attack. The moon city-state army retreated one after another, and the gravity ring fell one after another. With the power of Kaineng, the secret weapon of the moon, the Moon Army resisted the aggressive attack of the pirates in the universe and successfully held the territory. Although it was a great sacrifice, it still survived the crisis of being broken.

In 2589, the Mars Army made a comeback in disregard of the armistice agreement and attacked the United Nations Association with the Earth. The Moon Army sent Kaineng troops to support the Earth Army. The battle fell into a white-hot stalemate, and the pirates of the universe, the moon city-state and the earth were pushed to face a cruel battle of mutual destruction.
