Gene Martial Arts

Alien beasts invade, all life is devastated, gods are at war, great powers fall, and there is no way to compete. I, Gao Lijian, swear by my blood Even if you die without regrets, you will protect your family and country, draw your sword horizontally to the gods, sacrifice your soul and kill your soul. Gather the power of heaven and earth to suppress alien worlds and restore peace to the human race. [The early stage is more science fiction, and the later stage is more fantasy]
