MTL - Invincible Exchange System - Chapter 238 Pass the first pass

Have you ever considered, what is a Limit? Well, I have. I’ve seen people who were as strong, as wild animals. Those that were faster than the wind. Some that shined with intellect. Yet, what are the Limits of mankind’s strength, or intelligence?

No one seems to know. We develop more and more, seemingly without an end. What if, someone was the smartest in the world? Would that suggest the Limit? What if, someone was the strongest in the world? Would that be the Limit? Would that make that someone, more than a Human? These are just questions, but what if I saw people reach their Limits? What if I know what happens, when you break the Limits? What if I were to tell you about it, would you believe me?

Takahiro Nao, a 25-year-old drowning in debt and despair, lives only for his struggling family. Every sacrifice he makes is for them—until a selfless act costs him his life. Instead of the end, Nao encounters a Goddess of Benevolence who offers him a miraculous deal: “Live in a new world, and your efforts there will support your family back on Earth.”Reborn into the dead body of Naoki von Blackmore, the so-called “Failed Hero,” he finds himself burdened with the daunting task of saving the world by defeating the Demon King—all while supporting the family he cherishes. Armed with formidable powers yet haunted by his past failures, Nao steps into a dangerous realm of swords, magic, and ferocious monsters. Facing relentless enemies, harrowing trials of life and death, and an unyielding fate, he’s forced to confront the ultimate question: how far is he willing to go to protect the people he loves?Filled with emotional struggles, determination, unexpected humor, and a touch of romance, this story asks a powerful question to the readers: What would you sacrifice for the people you love?

To save a doomed fantasy world, I killed the main characters, then destroyed the game world, and fell into another timeline as the academy's top seat and rival to the protagonist.Now, I'm trying to save the world and steer it towards a better ending…But I'm the final boss.

Thanks to the Goddess, he was reincarnated into nobility!　That should have been great―― but the skill he got, 【Toxin Decomposition EX】 was simply too plain, and he was made fun of everyday at home……
