Just Entering High School, the System Insists I’m a Late-Life Great Emperor

The rating was just posted and will go up later [System arrives early] + [feel-good story] + [overpowered cheat] + [single female lead]

Jiang Feng is an ordinary student at Linchuan High School, with average aptitude and an ordinary family. The younger sister he has been fostering at home, Shen Weilan, has a Divine Phoenix physique and cultivates at an astonishing speed!

Countless classmates mock her, saying Shen Wanzlan is the real daughter and that he is just a picked-up wild child.

Teachers think little of him, the girl he secretly loves is disappointed, and he drifts through his days in a daze.

Who would have thought that three months before the college entrance exam, he would awaken the Late-Life Great Emperor System!

System: [Host, as a Great Emperor guarding a region, you fought the female emperor of beasts in your later years, were severely injured, and are about to fall.]

Jiang Feng: What is going on? I just started high school, didn't I?

System: [The system has awakened to help the host restore Great Emperor strength and revive the hope of the human race!]

Jiang Feng: Hold on, I'm not a Great Emperor! Did the system get it wrong!

Shen Weilan: My brother is clearly a shut-in, so why does he look so handsome when I see him beating up all the prodigies?
