MTL - Go Legend - Chapter 1 two dudes

Xia Ning is betrayed by her boyfriend who wants to marry another girl from a rich and powerful family.

Lee Se-Hoon, the blacksmith of humanity’s last desperate united force, fought against the demons until the very end. However, the result was mutual destruction, with the world coming to an end. The moment he took his own life over that futile conclusion—

“…What is this?”

He had regressed to his days as a candidate at the hero training institution, Babel Academy. Having obtained a second chance, he swore to use anything as material to gain victory this time. Anything at all!

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.

Drizzles in the wind, a small shop with pennants, and flower-like vintners.

Xinfeng’s fine wine, tenderly-fresh sunflowers shoots, and superb delicacies.

Lin Yan, Shaoyin of Jingzhao laid his eyes on the restaurant’s owner who has skin as fair as snow and beautiful apricot eyes.

It was pitiful and pathetic for a young lady from high-society to fall into the situation of selling wine…

Yet Shen Shaoguang thought: With wines and delicacies, and being able to see handsome young lads pass by…Life is treating her well enough!

Lin Yan’s expression was heavy, these young lads dress up fancily every day, showing off themselves and playing boring games like rooster fights and dog races…It’s time to straighten them out!
