Tutor's Strongest Right-Hand Man

Jokudera was seriously injured after a fight with a group of gangsters in Italy! Possessed by people from Earth who have traveled through time! Yu Feng was originally a super genius who learned everything quickly, but he himself was a freedom-loving person. He would retire after he had earned enough money to spend in his lifetime, so Yu Feng began to travel around. Finally one day, an air crash occurred on the way from Sicily to China, and he finally fell asleep in the vast sea! When Yu Feng opened his eyes again, he had already time-traveled into the body of Hayato Gokudera in the tutor. After checking, he found that Gokudera was too seriously injured! He must have not persisted! This should be considered a parallel world where the prison temple is dead! I was reborn in this parallel world of tutoring in the Prison Temple! So the newly born Gokudera began to show his prowess, began to slowly become stronger, developed various powerful explosives, and new fighting methods, which made Gokudera Hayato's combat effectiveness rise sharply, and Gokudera began to learn management, housekeeping, and other management knowledge! The purpose is to become that person's strongest right-hand man and his strongest helper!
