MTL - Marvel: Start with God of Destruction - Chapter 23

The strongest Hero in history, Nakamoto Keisuke.

He was summoned to another world in the spring at the age of fifteen years old, and when he successfully defeated The Demon King, he was already thirty-two years old. He had finished his role in another world and returned to Japan, but the reality that had been waiting for him was, “Middle school graduate with seventeen years of blank period” label. He couldn’t find a decent job and had no choice but to spend his days working part-time.

Before such a Nakamoto, a beautiful girl who self-proclaimed had come to return the favor, appeared. “I’m the reward for Hero who had defeated Demon King”, said Angelica, a girl who came from another world that persistently tempted Nakamoto to make her his wife. Together with a high school girl who looks like Elsa, his beloved girl that he lost in another world, Nakamoto with his cheats skills got caught in a harem life.

In the year 241 of the 6th era, Constantinople was in turmoil.Emperor Constantine personally lead his army, which was completely annihilated.

Beside the coast, a hundred-meter star gate is overflowing with light.

Outside the star gate, the army made of steel can’t see the edge at a glance.

On the sky, a fighter jet flew across the sky, interweaving the iron curtain.

In the distant ocean, aircraft carriers, destroyers, and frigates are all over the sea, ready to go.

All the muzzles were aimed at a figure walking out of the star gate.

“I order you to withdraw in the name of the Federal Command, otherwise, all-out war awaits you.”

“war?”

Ancient and Jinlai took a step forward, and his body rose against the wind. In an instant, he grew from less than two meters to a Chaos Demon God thousands of meters high. The brilliance of a white dwarf radiated from him, and his own gravity alone caused it to be caused by thousands of miles around. Lightning and thunder, tsunami tides.

He bows his head…

Looking at a toy-like war weapon.

Reaching out, a hydrogen bomb fell into his hand.

The electron degenerate star nucleus in the body releases helium, and the helium element expands. The terrifying high temperature instantly causes the isotopic elements of hydrogen to aggregate deuterium and tritium, and the energy explodes. The sudden white brilliance is like lighting a sun on the sea.

Before waiting for the sun’s energy to be released, he closed his hands together, and the blazing whiteness mixed with hundreds of millions of high temperatures was compressed and sealed in the palm of his hand, escaping less than half of it.

“I think you should choose peace.”

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.
