I choose a C ranked hero in another world, I was mocked online - Chapter 10: Get Stronger Through Exercise!

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

My reunion with her took place in the worst possible way.

“Nine Heavens cast down the Undying Tree, from the tomb the Immortal's bones were fetched;Taoist Venerable tut-tutted as they drank blood plasma, Old Buddha relished in the chew of meat;Beasts and livestock rang the Dharma Drum, city foxes and hole-dwelling rats boiled in the pot;In the Immortality Wine, the resentful spirits were fishy, at the Killing Banquet, the Dao Fruit was bitter!”In this world where Daoist Skill manifested, countless Sect Cultivators, Side Door Magicians, princes and scholars, officials of high rank and nobles all coveted immortality!Owl God Tomb, stealing heavenly secrets, Pearl Gathering Skill, Holy Infant Pill, bone effigies, Yin God Shrine, human-transformed monsters, Undying Elixir, Red Line Poison, Blood Immortal insects, Mermaid Meat, gold-threaded robes, Five Poisons Primordial Spirit, Seven Star Life Extension...They killed and harmed life only to steal the “Killing Dao Fruit” borne upon that Undying Tree!Until... a sly “Fishing Man” came to this world.Wang Yuan, born with the Small Book of Life and Death, had but a simple and unadorned dream:Amid bustling strings and smoky vistas, on a night bathed in moonlight, in peace and quiet did I lean on the rail, savoring the wind, toasting to the stars.With his “Bride in bridal clothes,” watching the sunrise at Taishan in the morning, admiring Qionghua in Luoyang at noon, and drinking under the aurora by the North Sea in the evening.“But you all smell so incredibly fragrant!No more, none shall escape, for today I shall crowdfund Cultivating Immortality! Please... my treasure, turn around!”The blood-red veil of the Bride abruptly fluttered to the ground.

Rebirth, Xie Tingyue’s face is solemn, holding on to the unknown and the “Great Power Economy” that has always been with him.

Goal: Shun down all kinds of swords and swords, protect yourself, protect your brother, and protect the useless disabled husband.
