I Just Became a Mage, So Why Am I Gaining One Health Bar a Day?

Xia Yu transmigrates to a world where everyone can change class, and awakens as a fire mage. But then he discovers that he has a talent that adds one full health bar every day, so he immediately makes a decision that goes against his ancestors' teachings. While other mages strive for bigger mana bars and higher damage, Xia Yu goes all in on building his physique. [Straw Double] When damage would reduce your health to 1%, you become immune to that hit. The cooldown resets once your health returns to 100%. “Huh? Each health bar can block one hit, and there's no cooldown?” [Contract: Balance] Converts health into three times that amount of temporary mana. “The bigger my health bar, the bigger my mana bar! Who says a mage who invests in constitution can't kill anyone?” Assassin: “A fire mage? Let me show you what the harshest father of all spellcasters looks like!” But the assassin's strike doesn't make Xia Yu's health bar budge. The assassin looks up, trembling. “Hey... Can we still make up?” When a frost dragon appears, all the other prodigies are beaten to a pulp. Just as they are about to be wiped out, Xia Yu steps forward. “He took the ultimate attack to the face and survived? And killed it in one move?” When they encounter an enemy sword saint, a mage suddenly appears in the rear as they try to break through. “What do you mean, you know a little close-quarters combat too? Soul-Eroding Flames aren't meant to be wrapped around your fists! Ribbit!” Years later, the Abyssal Rift opens, and extraterrestrial demon gods descend, bringing despair with them. When they see space and time evaporating in the intense heat, and the laws of nature collapsing as reality warps, they all begin to tremble. “Would you believe us if we said we took a wrong turn?”
