- Description from novelbuddy

In the age of interstellar exploration, three hundred years ago, Mage explorers from the yellow river planet took their first step towards outer space.

It was a joyous event for every mage on that planet, yet unfortunately, space is dominated by other races.

The Peak level Mage from the Yellow River Planet was the weakest power in existence among other outer space races. It's a cruel reality for everyone.

From then on, every mage from the Yellow River Planet began to increase their power level by consuming outer space resources.

Then they constantly researched, upgraded the power level system and tried to pave the way for the next generation of space explorers.

Now, our MC Vincent Carey's ambition is to be the next generation of space explorers.

How is he going to increase his strength and compete among other races to get resources?

How is the unknown little yellow river planet going to be known and feared by others?
