Feng Yu Jiu Tian - Volume 17 Chapter 9 part1

Lu Zhou wakes up to become the world’s most powerful and oldest villainous Patriarch, and finds that he has nine notorious disciples who are full of evil. His eldest disciple is the leader of the Nether Sect with thousands of minions, and his second disciple—Sword Devil—always slaughters others at the slightest disagreement…

Having a rough life growing up, Wang Tong had numerous dreams of living a better life. However, his alcoholic foster father sells him off as a space settler of the distant planet Norton for some pocket change. Soon after his arrival, the Zergs overran the planet and obliterated its defenses in a matter of minutes. What awaited Tong on Norton was more than just an unbearable environment – its gravity alone was five-times stronger than earth – there were also swarms of bugs, constant hunger, thirst, and desolation.

While he lives a year of total carnage and survival, humanity’s Confederation eventually overcomes the Zergs on Norton and the powerful survivor Wang Tong is given a recommendation to a once famous, but now dying military academy where he begins his life anew.

Alien civilization invaded, global psionics recovered, and a game against alien civilization was born…

What? All transactions in the game can only use psionic coins?

Can’t you quickly increase your strength without burning a lot of money?

Su Yu smiled while standing beside the world’s largest psionic spring.

I have tens of billions of psionic coins! Are you scared?

…

Ps: There are already 1.6 million words of the old book, and the credibility is guaranteed.
