Everyone Picks the Evil-Warding Sword Manual, but You Choose the Indestructible Vajra

This is a parallel world invaded by monsters, where the arrival of the Main God Space gives humanity all kinds of martial arts techniques and skills to fight back! When countless martial arts manuals appear, everyone pursues the quick and easy-to-learn Evil-Resisting Sword Manual, while dismissing the Vajra Indestructible Divine Skill, which can only be used five times in total! Jin Gang feels around down there and rules out the castration sword technique first. The Vajra Indestructible Divine Skill is obviously the one to choose! No need to think twice! The whole internet mocks him. He'll only be able to use it five times in his entire life! They laugh that he's destined to remain a nobody forever. But who could have guessed that those five uses wouldn't be the end, but the beginning? By the time his training is complete, Jin Gang will have reached the pinnacle of martial arts! While everyone else is cutting themselves with a sword to get ahead... Jin Gang quietly cultivates a golden legend! At last, the whole internet understands what true invincibility means! When his opponents discover that this immovable golden lump can still spend every night carousing, the delicate masters who castrated themselves to join the trend all over the internet are left fuming!
