On the surface, she’s a gay high school boy. In reality, she’s the hacker known as Z, who hunts criminals on the Internet. A girl dressed in men’s clothes; a master at playing games, punishing evil, and having the highest skill in seducing girls. When people learned that “he” was actually female, the entire population blew up!

Fu Jiu: “Great Deity Qin, do you have a girlfriend?”

Qin Mo puts down the laptop: “I don’t have one.”

Fu Jiu starts to seduce in a low voice: “In that case, you have one starting now. Me.”

Hearing this, Qin Mo leans over tyrannically.

Fu Jiu is dumbstruck: “Hold on! What are you doing?”

Qin Mo: “Using my privilege as a boyfriend.”

- Description from Novelupdates

The Interstellar Fleet from the game appeared before the ordinary youth, Bai Zhongqi, and the player became the Chancellor of the Empire, opening a new chapter for his brethren and Earth as they set out for the vast sea of stars. The nations of Earth were engaged in cunning and fierce competition for the future of the Intergalactic Era. Bizarre and varied alien civilizations were waiting for Earth’s explorers to discover them. It was a cruel, dark jungle where only the fittest survived, and a world filled with opportunities and magnificent adventures. But for Bai Zhongqi, this was simply a laid-back story about leading Earth’s friends, furiously climbing the tech tree, beating up aliens, and dominating the Galaxy.

The world is under invasion by creatures from another world. Martial arts became the most important skill in this world, and all cultivators strived to improve their skills.

Chen Yiming transmigrated to this world with a special ability – the Martial Arts Talent System. The system allowed him to use Skill Points to enhance his talents infinitely.

What if he was born with a physique that was not suitable for cultivating martial arts? He could slowly train in the mountains while waiting for his Skill Points to accumulate. When they reached a certain amount, he could use them to enhance his talent and automatically acquire the physique needed for cultivation.

What if he did not have the complete volume of the martial arts technique he practiced? It wasn’t a problem. With sufficient enhancement to his talents using Skill Points, he could automatically deduce the missing parts in the book.

With the Martial Arts Talent System, he could defeat everyone who got in his way. He could easily climb the ranks in the martial arts world – becoming the top disciple, the top cultivator, then the grandmaster.
