Mushoku Tensei: Jiahao Starts by Mocking the Man-God to His Face

[Mushoku Tensei + System + Rudeus's Older Brother + Harem + Multiple Heroines]

After being hit and killed by a dump truck, Lin Fan unexpectedly transmigrated into the world of the anime Mushoku Tensei and awakened the Jiahao System. After taunting the Man-God to his face, he became Rudeus's older brother, Caleus.

He would make up for past regrets. The scumbag Paul wouldn't die, or at least not before the family was reunited. The protagonist would save Eris and Sylphie's families, as well as everyone in their villages. He would also make up for Aisha's regret at never getting to study, and so on. He wouldn't become one of the Dragon God's subordinates, only an equal friend, with the occasional sparring match. The protagonist would reshape Rudeus's personality so he was no longer as timid as in the original, and at least seemed like a normal person rather than a cowardly, insecure wreck.

Facing Rudeus, his older brother Caleus showered him with affection: "Little bro, you seem to have gotten weaker."

Rudeus immediately broke down. "Nooo... Big Brother!"

After saying that, older brother Caleus unleashed his Susanoo on the spot and trained Rudeus in private, spinning him around like a top.

After years of guidance, he completely reshaped Rudeus's personality.

Roxy came to tutor him: "Heh, compared to a true genius, I really am nothing at all."

Eris: "Hehe, Caleus is the strongest!!!"

Sylphie: "As long as he's here, everything will be all right."

Many years later, a group of crusaders spoke up on the spot: "Caleus, what on earth did you do? Without Lord Dragon God, how are we supposed to stand against the Man-God?"

Caleus smiled faintly. "It's simple. I'll just become a god myself."

With that, Caleus grabbed the Man-God by the head and refined him in an instant.
