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."

One day, many doors suddenly appeared in the world.

At the same time, a power called "Truth" resonates throughout the world.

Someone awakens to the truth of Newton, the father of mechanics, and learns the magic of manipulating gravity to make things fall from the sky.

Someone awakens to the truth of Oppenheimer, the nuclear demon: with a wave of his hand, a city falls into desolation.

Some have awakened to the truth of the banished immortal Li Bai, singing and drinking to admire the snow-covered sword, soaring straight to the heavens to grasp the moon.

Some have awakened to the truth of Azathoth, the god of blindness and folly, and wish to shroud the world in a fog of delusion.

Science, literature, theology... When all the familiar written words become incredible and extraordinary mysteries, where should we, in our ignorance and folly, go?

What kind of dress is this? As soon as I entered, the dress owner, Jizi, posted a photo of the good stuff, followed by two from wealthy woman Ester! In the women-only chatroom, Ye Qiong's arrival caused a huge SAO commotion. [Yae Shenzi]: Wonderful! Let's put this plot in the novel! [Ester]: No such thing! I'll give you 10 billion credits!

You're not even letting me off, are you? [Bronya]: Ye Qiong, is my mom doing well with you? [Group Leader Jizi]: What did you do to my other self? [Kafka]: I have a child... What? You want the child too? You want to eat rice bowls!? [Xing]: That's not impossible, actually (accepts the red envelope) [Ye Xun'er]: Brother Ye Qiong, I've become the Flame Emperor! Come and play with me~ [PiPiDong]: God of the Gauze Sea, I’ve given you the rabbit.

[Lord] + [Expansion] + [Development] + [Conquest]

Lance, a transmigrator, is a genius who has already reached the pinnacle of knighthood at the age of eighteen, in a world of swords and magic filled with races such as dragons, elves, orcs, and goblins.

Some people transmigrate and become the ruler of a country!

Some people have even transmigrated and become cultivators!

...

Leveraging the unique advantage of being able to exchange resources on the Human Spark platform.

Lance's path to becoming a lord is destined to transcend the mundane and forge an epic.

This is a parallel world; please do not take it personally.
