My Body is Too Resilient, It Can Cultivate Its Own Techniques

When Jiang Chen woke up, he discovered that his body could actually cultivate martial arts on its own."After a night of hard work, you've broken through the first layer of the Body Refining Technique and obtained the Copper Armor External Technique.”"Because you didn't take any pills, your Prime Devil Strength Technique didn't have the slightest bit of spirit, and your cultivation made no progress." "You obtained the Hundred Refined Horizontal Blade, and your Blade Drawing Technique broke through in an instant." "You successfully broke through the first level of Blood Devouring Divine Technique after killing someone for the first time." "You successfully broke through the first level of Phantom Steps after watching a coquettish vixen." "You stared at the sun for a minute, and your Sun Shooting Arrow reached the realm of Thousand Steps Piercing.”"…" Jiang Chen, who originally had average talent in martial arts, obtained the Cultivation System. He could cultivate any martial arts he wanted by himself.
