Federation, Empire, Corporate Alliance, this is an extremely dangerous interstellar era.

All intelligent creatures can take up a profession with extraordinary power through a special ceremony, which is also called a professional.

Leon was both unfortunate and lucky to travel to this world.

The unfortunate thing is that as an ordinary person, the probability of him dying in such a dangerous world is basically 0.

The lucky thing is that he awakened two powerful talents.

Traveler: Every time you experience a big event, you can start a new journey.

Console players: As a player behind the wall, the number of professions you can take up is...∞.

When Leon first came to the world of one person, he took up a profession called [Refiner].

When Leon first came to the world of Dragon Clan, he took up a profession called [Mixed Race].

When Leon first came to the world of Naruto, he took up a profession called [Ninja].

When Leon first came to the world of Collapse Iron, he took up a profession called [Commander].

...

For countless years, in this starry sky intertwined with blood and fire, Leon has unknowingly reached the peak.

He looked at the information on the panel in front of him, [Immortal] + [King] + [Star God]… The corners of his mouth could not help but curl up.

"It's time for this starry sky to welcome their emperor."

Bai Xiao arrived and looked up. Not only did he see this bizarre and magnificent world, he also saw the career modifier he downloaded before crossing.

"Consume all the experience of the secondary careers [Biological Mecha Master], [Mystic Realm Scientist], and [Special Hypnotist], and turn them into millions of potential points, and all upgrade and modify the main career [Fighter]!"

"I... got the golden ultimate career [God of Fighting]!"

The world's largest urban agglomeration, a rainy night.

On the ground, countless killers and fighters fought for their lives, and a large number of metal mechas and biological armor exploded and self-destructed. Blood and fire mixed, everything fell into primitive violence and chaos.

At the top of the tower, Bai Xiao stood quietly in the rain and darkness, like a stiff and terrifying statue. His scarlet eyes looked down, restrained with blood and cold with madness.

He jumped down, his windbreaker dancing wildly.

The God of Fighting, descended on the final battlefield!

The cold voice echoed in the city sky.

"Next, I will kill everyone present! If you have the ability, come and stop me..."

The prosperous and luxurious modern city, the consumer era where entertainment is supreme.

Under the surface of peace for seventy years, there is another crazy and bloody world.

The fighters who master the secrets of the school and the killers controlled by the battle mode, both sides start a terrible fight to the death.

The metal mecha with terrifying energy and the biological armor extracted from monster cells, the cruel battle between new and old technology has begun.

In this era alienated by machinery and external objects, shouting for the power that belongs only to humans may be unimaginably romantic...
