MTL - Start with Batman - v2 Chapter 385 "Amazing Speed"

Our protagonist was a Mexican who died on a flight, when he woke up he found Apollo who reincarnated him as the grandson of Gaius Octavian Turino (Augustus) the first Roman emperor, having a mission in hand to conquer the New World to save the Roman polytheist world and his existence.

The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

An accident gave Su Hao the ability to reincarnate infinitely.

But who can tell him why he can’t live past five years of age every time he is reincarnated?

The universe is dangerous and unfriendly to children.

Su Hao decided on his first small goal — to become an adult.

“How could I not even become an adult!”

…

Amidst Su Hao’s millions of reincarnations, one time after another. After obtaining enough knowledge, he discovered the way to become a god.

This is a mortal’s path to divinity. Maybe… you can too!

Is magic really a wish machine?

No! In a universe where magic actually exists, the ultimate nature of magic must be as simple and beautiful as the laws of physics.

This is the story of a mass-produced magic warfare tool man who learned the ultimate nature of magic.

But so what?

Just as a bird can fly without understanding aerodynamics, so a wizard does not need to understand the ultimate nature of magic to use magic.

Knowing the ultimate nature of magic does not mean that the tool man can become a great magician.

But the desire for knowledge is human instinct, and curiosity is the first driving force of human civilization. Humans hope to understand the inner workings of magic, even if it is supposed to be unreasonable.

An inquiry into the ultimate nature of magic, without any justification!

The story in the book takes place in an age where steel dances with gunpowder.

Here, muskets are in the ascendant, armor is still the protagonist, military theories are changing with each passing day, and innovations in systems and craftsmanship are emerging one after another. And this world has one more thing than ours: magic.

The world is undergoing earth-shaking changes, and no one can stay out of it.
