Will Kai Live Forever? Then I Have to Practice Forbidden Arts.

[Revival of Spiritual Energy + Alien Invasion + High Martial Arts + Caution + Decisive Killing] (No system + growth flow) The universe undergoes a sudden change, alien races arrive, spiritual energy revives, and the entire population begins to practice martial arts. Shen Qing, who traveled through time and became a primary school student, unexpectedly awakened his immortal body. He could be reborn with blood and become immortal forever. It just so happens that demons are rampant and causing harm to the world. In such a dangerous environment, Shen Qing realized a path of cultivation that belonged to him. That is, practice forbidden arts. Forbidden techniques can be achieved quickly, but they are extremely harmful to the human body, ranging from consuming one's lifespan to causing one's body to explode to death. The Seven-Injury Fist detonates the energy and blood of the meridians and merges into one punch, injuring the enemy by one thousand and damaging it by eight hundred. When practiced to a great extent, the user will definitely die. Blood Shadow Escape consumes the whole body's essence and blood and melts it into the escape technique. The speed is increased by ten times. You will die after using it. Crazy Demon Sword Code: Stimulates all the nerves in the body, squeezes the limits of the human body, and consumes lifespan. It is like a crazy demon. Those who have mastered it will bleed from the seven orifices and explode to death. … The forbidden technique that others regard as poisonous snakes and fierce beasts, in Shen Qing's hands, is the heaven-reaching treasure technique that can kill immortals and gods. As a result, the entire world's style of painting began to look wrong. "Where did the elementary school students come from? They are so terrifying!" "I swear to God! I saw with my own eyes a primary school student, driving an eight-door armor, killing a demon king-level monster with a seven-injury punch!" "What? He actually practiced the method of dismantling demons to a great level? And he's not dead yet?" … Shen Qing picked his nose and said, "You're making such a fuss, give me a crazy swordsmanship!"
