Douluo Continent: Disciple Tang San, righteous yet evil

Lin Mu unexpectedly transmigrated to Douluo Continent and awakened the Nawa Summoning Martial Soul.
After ten years of cultivation, he reached level 46 Soul Master and accidentally bumped into Tang San, who was preparing to enroll in school. Just then, the golden finger he had been waiting for for sixteen years finally arrived.
It's a very simple panel.
[Main Quest: Take Tang San as your disciple and reshape his values. The greater the contrast, the richer the reward. Completion: 0%]
Under Lin Mu's tutelage, Tang San gradually became wicked in his righteousness and began to unlock other summoning devices.
...
Years later, just as Tang Hao was about to reunite with Tang San, he discovered that Tang San's personality had undergone a complete transformation.
Tang San: "Since you've already left, why did you come back?"
Tang Hao: "Mistress, I will always be your father."
Tang San: "I only have a master and a mother, not a father."
Xiao Wu: "Brother, do soul beasts deserve to die?"
Tang San: "Once a soul beast, always a soul beast!"
Upon completing the main quest, Lin Mu received the final reward—the Asura Armor.
What surprised him even more was that the Asura Armor evolved into the Hellface Asura as soon as he got his hands on it.
(Abuse of Gang, abuse of Shrek Academy, Tang Hao and Tang San turn against each other)
