MTL - Mysterious Lord Gu’s Palm Treasure - Chapter 164 master

By the time Li Qingran realized she had been transplanted into a book, she had already muddled through seventeen years.Growing up together as childhood sweethearts with the male protagonist Xie Ying’an, their relationship was rather passable.Endowed with the halo of the male lead, Xie Ying’an was like a hacked character from birth: good-looking, from a good family, with good academics...Li Qingran vaguely remembers that she was a female supporting character in the book, whose ending was not good due to constantly making trouble for the female protagonist.Li Qingran shuddered, feeling all too familiar with this plot; getting involved or not could both lead to trouble, so she needed to come up with some strategies to cope...PS: Unrequited love theme, male and female leads are high school students, and they do not engage in early romance.

I was summoned to a ruined world and received the ability to create various things. Since I don’t have a house to live in I will make a house. Since people are gathering at my house I will make a town. Since the town is being attacked by monsters I will make the strongest weapon and repel them. Using my infinitely charging magic power I will remake this world as I please.

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.

What the hell is this? What the hell happened here?
