The world changed, and dungeons appeared.
Xu Mofu chose the S-rank Guardian Heart class. Using his protection and counterattacks, he helped his three older sisters and younger sister reach the pinnacle of Great Xia.
In the end, Xu Mofu, the greatest contributor of all, was driven out of the Xu family by the four ungrateful wolves.
When he opened his eyes again, Xu Mofu was back on the day he first chose his class...
Right in front of his eldest sister, he chose the least favored class of all: Rogue.
His eldest sister broke down, his second sister froze, his third sister went berserk, and his youngest sister...
But Xu Mofu still had his Guardian Heart class, and it synergized with the Rogue class.
When he reached the pinnacle of the world, the four ungrateful wolves were consumed by regret...
“You can't hurt me, and your attacks hurt you instead. The stuff in your backpack ends up in mine, too?”
“‘Pickpocket Saint’ sounds awful!”
“I just forgot to turn off auto-loot!”
The logic is clear. The structure is clean and crisp.
It's an old routine but it's well written. Good luck to the author.
