- Description from novelbuddy

“In a realm where cultivators command the elements, bending mountains and traversing celestial rivers, their power is unmatched. Among these mighty beings, the body refiners are renowned, their mere presence capable of rending the heavens and reshaping landscapes. Their skill in crafting transformative elixirs commands respect and admiration. A legend in the Upper Realm, known for an ascension gone awry, suffered the loss of his physical form. Yet, in a stroke of fortune, he discovers a way to regain his corporeal existence. Embarking on a rejuvenated journey in this mystical land! Resolved to surpass his past achievements, he vows to ascend beyond the ranks of experts, charting a path filled with power and ancient mysteries.”

Soul Mechas were forged to punish the Eldritch Monsters that attack this world from Beyond the Glass.But they can only be powered by those who bond with ancient mythical souls from that world.Unfortunately, souls are only attracted to negative emotions: helplessness, anguish, and loss.

But what can a loser say? As I laid dying, I was forced to listen to the hero’s gibberish:

“If you are born again, I hope that you will live a kind life!”

But huh? When I opened my eyes again, I was back in the past.

“What do I have to do to live a kind life?”
