Nidome no Yuusha - Chapter 148 - Returner, Destroy Your Body with Cheap Tricks

In her previous lifetime, they had married for five years. He meant everything to her, but she was thrown away like an old shoe.

He crossed over to a new world where humans have magical power. They are called warriors. They use their power to kill the monsters that appear out of nowhere. Dragons, Dungeons, and Magic users are pretty common in this world. If you want to live in peace, you need to have that power. You can also become a powerful clearing dungeon.

In this dangerous world, he has a system that can help him grow stronger. But he didn't want to be a high-profile warrior who attracts much powerhouse attention or become a lab rat. He wants to be Low-profile and grow strong using his system.

This stands at the forefront of strategy guides to Life (a shitty video game)!
