The Greatest Beast Tamer of Earth

In the year 2050, a colossal spaceship suddenly appeared above Earth.

Governments worldwide panicked as they saw the vast spaceship that had just teleported near Earth. Before they could even understand the situation, one humanoid alien emerged.

“Humans, I am your ancestor.”

“We distributed our life code with an atmosphere-changing module device to many universes and galaxies, hoping to recover our numbers after the war.”

“I will now awaken the earth's mana core and install a dimensional dungeon system, which will open many dungeons around the earth.”

“I'm also connecting Earth with a System.”

“This will help you awaken faster and get strong enough to survive in our universe. Gaia(system) will explain to you other important things,” He finished and then disappeared with the spaceship as he was never present there.

[Hello Humans, I am Gaia I will help you all to awaken and become strong]
