Monsters Are Rampant, I Transform into a Martial Arts Master

[The end of the world + monsters + urban martial arts + no harem + partial group portraits + invincibility + forming a force] As two planets collided in the universe, an unknown alien energy was scattered. After this energy is absorbed by plants and animals, it mutates into powerful monsters. Monsters are raging, constantly compressing human living space. The crystal core of monster beasts has become the only way for humans to become stronger... In the wasteland, technology has been corroded, order has been broken, and civilization has ceased. After a hundred years of confrontation between humans and monsters, the world today only has the major holy cities where civilization still exists, and Gecheng, the frontline against monsters. At this time, the hierarchy was put on the stage again by those in high positions, forming two completely different groups: people inside the city and people outside the city. The people at the bottom have only one belief: live! The Song Dynasty crossed over and brought with it the martial arts panel system. Full-level [Hunyuan Palm], [Feitian Shenxing], [Heart-Destroying Palm], [Toad Kung Fu], [Nine Yin Manual]... There are so many magical skills and unique skills, but you still say that you are not a martial arts master? PS: The overall rhythm is fast and slow, everything serves the development of the plot.
