Jiang Yu traveled to the world of Douluo and awakened the King of Martial Spirits. That's right, it was the game from the previous life, and now it has become Jiang Yu's martial spirit. The first soul ring activates the hero armor. The second soul ring activates the hero Hou Yi. The third soul ring... Then absorb the immortality and gain the ability to summon multiple heroes at a moment's notice. Countless heroes were summoned by Jiang Yu. Tang San, Yu Xiaogang, gods, all kneel down to me. I am the king.

Jiang Yu, a medical student in his previous life, somehow traveled to the Douluo world and became an orphan of the Blue Lightning Tyrant Dragon Sect. Because it was Luo Sanpao who awakened his martial soul, and because of his innate soul power level 0.5, He was discriminated against by everyone in the Blue Lightning Tyrant Dragon Sect. When he was eight years old, he was expelled from the Blue Lightning Tyrant Dragon Sect on the charge of "theft" and deprived of his "Yu" surname. "Hmph, I don't care about the Thunder Tyrant Dragon Sect and the 'Yu' surname!" Jiang Yu left the Blue Lightning Tyrant Dragon Sect, relied on modern medical techniques to cure Queen Tiandou, and became Viscount Tiandou. Rely on the knowledge of the previous life to build pistols and grenades. The routine is lonely and Bo, and you get the Ice and Fire Eyes. In the two eyes of ice and fire, he absorbed the power of the Dragon King, and his martial soul evolved, turning into the twin martial souls Ice Dragon King and Fire Dragon King. This is where Jiang Yu's invincibility begins. Tang San: Damn it, what kind of hidden weapon is this? It's actually more powerful than my Tang Clan hidden weapon. You already have a way to kill me! Yu Xiaogang: Damn it, Luo Sanpao is the same martial soul, why can his martial soul evolve? It's not fair! (Not joining the group, torturing Tang San, multiple female protagonists...)

Jiang Yu traveled to the world of Naruto for the first time, and for the second time to the world of Douluo, awakening the martial spirit Sharingan. Because of his innate soul power, he was targeted by the master Yu Xiaogang, who insisted on becoming his teacher. However, Jiang Yu, who had traveled through two lives and had the experience and theories of both lives, decisively refused to become a disciple. Master Yu Xiaogang: Innately full of soul power, he should be my disciple. This just proves my theory. Tang San: As a disciple who actually refuses to be a teacher, you already have a way to die. You two are really sick! Jiang Yu ignored the two of them and developed his Sharingan. Level 10 Magatama Sharingan, Level 20 Magatama Sharingan, Level 30 Magatama Sharingan, Level 40 Ten Thousand Sharingan... Relying on the ability of the Sharingan, he developed soul skills, studied the origin of soul power, and created a new martial soul system. (Mainly based on Dou Yi's original work)
