[Servant upgrade system + light humor + casual farming + pseudo-invincible text] The protagonist who traveled through time and became a wizard gained the gift of immortality. While having unlimited lifespan, he also gained a little mental power every year. Therefore, although he was only obsessed with the research of alchemy and potions, he still had more than 600 points of terrifying mental power after staying in the small village for 570 years. "Don't be afraid, everyone. Although his magic power is strong, he only has a few small spells. If you rush over, he will be dead!" "What, isn't he raising a puppy? How did he turn into a six-eyed devil dog from hell?!" "I'm close, suffer death! Damn it, how can he have the power of a paladin and the defense of an earth knight?! This guy is not a pure mage, everyone, be careful." The protagonist said, I just want to do research in peace and quiet. You guys are coming to die one after another. Isn't it good to be alive? The Holy Spirit wizards met and voted: "How about giving him a seat in the Wizarding Alliance?" "I object. He is too troublesome. It is said that the goddess of light has planned to send a clone to catch him." "Yes, and the demonic tide has become more and more frequent recently. According to me, let him go to the frontier of the wasteland to build a defense tower." As a result, a mage tower stood on the path of the Abyss Demon Lords. Inside the tower lived a 'young' wizard who liked to do research. By the way, his name is Dis. He is 570 years old. He is really not interested in fighting and killing. His only hobby is doing research. If anyone refuses to listen and wants to disturb him, he will have to let Phil eat more. Phildo is one of his pet puppies. But Phildo is not the most ferocious of all pets, the most ferocious is the cute little hamster.
