After Rebirth, I Took the School Beauty to Serve as a Soldier

In his previous life, he was the sharpest knife in the reconnaissance company. He followed the squad leader through life and death. In the end, the whole company was destroyed in the nameless valley, and no bones were left. When he opened his eyes, he returned to the senior high school classroom in 2008. She is fourth from the bottom, and her deskmate is the most famous monitor in the school. He couldn't understand the formulas in the textbook, but maps, ballistics, distance measurement, and combat were all engraved in his bones.

He wanted to get back the life he owed to the squad leader and the debt he owed to the company one by one.
