Resurrection of Spiritual Energy: That's It? I Want to Save the World!

In the first year of the Spiritual Era, seven unique meteors fell to the earth, ushering in the age of spiritual energy on the earth. However, along with it came the terrifying alien Zerg who wanted to destroy the entire world. Li Yu, a descendant of the ancient martial arts family, originally thought that the martial arts books passed down by his ancestors were all lies. However, with the recovery of spiritual energy, he was surprised to find that injecting spiritual energy into them would lead to genuine training secrets. As a result, the Yi Jin Jing injected spiritual energy and became the general outline of Taoism in the world! The Six Meridians Divine Sword is infused with spiritual energy and turns into a Heaven-reaching Immortal Sword Technique! The Arhat Fist is infused with spiritual energy and becomes a powerful Vajra God Fist! ... Li Yu, who held these secret books, looked at the alien Zerg who intended to destroy the world and smiled disdainfully: That's it? Many years later, when asked how he saved the world, Li Yu waved his hand modestly: All it takes is hard work and a billion talents. This novel and its characters are purely fictitious.
