Douluo: Starting with Nine Systems, Isn't This Invincible?

Lin Ya was reincarnated in Douluo Continent, and was picked up by Bibi Dong and brought back to Wuhun Hall to raise him. Unlike other time travellers, Lin Ya not only has systems, but nine of them! It's just that these nine systems can only be gradually activated when his martial soul awakens. When Lin Ya was six years old and ready to awaken his martial soul, he felt numb when he saw his nine major systems. "Digestive system? Nervous system? Motor system? What are these? What's wrong with you?" However... Lin Ya couldn't help but fell into deep thought as he watched himself transform into the digestive system of the Taotie Martial Spirit. It seems... These nine major systems are not that deceptive, right? [Fan of Douluo, the position of Wuhun Palace, multiple female protagonists]
