Diablo Volfir, a mighty magician, was sealed for aeons due to the schemes of the 12 Gods, but 66666 years have passed since then, and he descends to earth once again!

When human beings ventured into the Interstellar Age, they encountered the Ochs Civilization, and thus followed the first Interstellar War.

Lost territories continued to increase along with the skyrocketing casualties. Eventually, humans were forced back into the Solar System.

In the 58th year of the Federation, Lin Fan, a traverser from Earth, graduated from the Interstellar Military Academy and entered the Federation Fleet.

That then signalled the day of the humans’ counterattack!

From dominating the Milky Way to the entire Universe, mankind never stopped.

This is a story of a traverser leading mankind to rule the Universe!

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.
