MTL - Cultural Invasion In Different World (Cultural Invasion into Isekai) - Chapter 51 Cooperation

A young boy named Tang Jie was searching for a path into immortalhood when he happened to save an immortal in need, resulting in the latter owing him a karmic debt.

What? You want to repay me with mere Spiritual Enhancement Pills? Is that how cheap you view your life to be?

As a result, Xu Muyang ended up having to drag the brat with him.

You’ll never shake me off now, thought Tang Jie.

To save a doomed fantasy world, I killed the main characters, then destroyed the game world, and fell into another timeline as the academy's top seat and rival to the protagonist.Now, I'm trying to save the world and steer it towards a better ending…But I'm the final boss.

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

- Description from Novelupdates

Shi Man was the best special agent in the organization, and she was supposed to retire in peace, but they came after her to purge her anyway. She died exhausted after turning the tables against the organization’s agents… but was reborn, transmigrating into a book as its villainess! The villainess’s family is rich and powerful. Being the only daughter, her mother and brothers would pamper her out of control, and she was engaged to the male lead at birth. Yet, the body’s original owner messed up big-time despite being dealt the perfect hand. She harassed the female lead to win the male lead’s attention and affection until she eventually incensed the male lead. He threw her into the colosseum ring, where she was torn to pieces. Her family naturally went all out to avenge her and ended up suffering multiple casualties as they fell into desperate straits…

On the other hand, when Shi Man reincarnated, she told the male lead that they should go their separate ways and pretend they never knew each other even if they met again. She even paid the female lead with emotional duress compensation and told her they had nothing to do with each other from then on. However, after parting ways with them and preparing to begin a new life, the male lead regretted his choice and started wooing her. The supporting male characters who were never interested in her also had a sudden change of heart, and even the female lead was now offering to be her follower! Staring at the mob flocking around Shi Man, the Shi family was furious. “She belongs to our family! Stay away!”
