City of Sin (Yanyu Jiangnan) - Vol 1 Chapter 10: Start From the Top

I fell into a game world out of nowhere with an instant kill skill.
And then somehow, I became a bigshot.

I, the mighty Telepath Starlord, got banished into the mortal world. The days in the mortal world are much better than those in heaven! Everything is here — money, authority and most importantly stunning beauties! I am from a rich family. Yes, I am indeed wealthy now. The kind of wealth where you would not want to displease me. Domineering CEOs, military big shots, business geniuses, you name it — I know them all! I know everything you are thinking about. You can’t defeat me anyway, how are you going to go against me? A century in the mortal world is only equivalent to a hundred days in heaven.
As an urban banished immortal, I will enjoy the heck out of my time in the human world and a huge commotion would arise in heaven!

Demons, devils, ghosts and monsters

Plunge the mortals weak in horrors;

Arms of gods and blades of devils,

Shroud the world in untold evils.

Lu Sheng was an ordinary civil servant in the modern world. After waking from a drunken stupor one day, he found himself trapped in a dangerous world where demons, ghosts and supernatural monsters terrorize the land.

In this world, ordinary mortals live in dark fear and helplessness, without any means to fight against the supernatural.

As Lu Sheng struggles desperately for survival, he stumbles upon a game mod he had designed for a mobile phone app in his previous life. It unexpectedly becomes his special ability, which enables him to instantly level up any skill he learns, albeit at a cost.

Thus, Lu Sheng begins his journey, striving for power beyond the reach of a mortal as he treads the way of the Devil…

After transmigrating into a beast world, Rong Mingshi discovered that the people of this world experienced widespread mania. For example, when their emotions were abnormally agitated, they would become destructive beasts. If their emotions were abnormally low, they would shrink into their young beast form.
