Divine Lucky Star - Chapter 163 - : Dinner Party

The universe gave me another chance after life screwed me over. My second life brought me to a world where people breath fire, walk on water and some people with special eyes that give them bullsh#t powers. Well, I got the gamer ability. And I’m gonna use it to stand at the peak. But it's gonna be a long journey before I reach that summit. SI - MC.

In a modern world where cultivators need a place to cultivate or vent their boredom, there are private businesses that set up instance dungeons with the aid of technology and cultivation magic to enable cultivators to train and commoners to experience the life of cultivation. They are called dungeon suppliers.
Xie Jin's one and only dream was to be a dungeon supplier and when his only relative passed away, the relative's inheritance gave him a plot of land and surprisingly, a 'System' Module which the relative had previously used.
With the help of the system, Xie Jin decided to pursue his dream of becoming the number one dungeon supplier.

Once time travels, Wei Han awakens the immortality system!

In this dangerous and mysterious world, he decided to live forever!

“What’s the point of fighting and killing? Isn’t it nice to hang up?”

“Enemy? Doesn’t exist! As long as we cut the grass and roots, I have no enemies!”

“Exposed? Impossible! As long as no one is left alive, no one will know how strong I am!”

The sun and the moon are flying like a shuttle, and the sea is changing!

With a cautious heart, Wei Han silently walked alone on the road to longevity.

A rare martial arts wizard in a thousand years?

The rare immortal cultivator?

Suppress the eternal holy land of immortals?

After all, it is no match for the passage of time and burial!

Only Wei Han sat and watched the wind and clouds surge, and finally became invincible in the world!
