MTL - The Demon King Took Off His Little Horns - Chapter 138

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.”
