Uncle Liu the Gatekeeper

When his grandfather came back that night, the first thing he said was, "Since you're back, I can finally give you back your place as principal. I'm way too old to be doing this." Gao Peng's grandfather unceremoniously dumped his role as principal of Tiange Academy back to Gao Peng, and he wasn't taking no for an answer.

"By the way, Grandpa, do we have any combatants in the group who were discharged due to injuries or some other reason that would like to be transferred from the frontlines? I would prefer it if they have a Lord or King-tier familiar with them," asked Gao Peng.

His grandfather looked at him strangely. "Of course we do. You even know him."

Gao Peng frowned. Do I know someone who fits that description? A name suddenly popped into his mind.

Uncle Liu! Liu Shaotang, who once lived next door!
