MTL - Slowly Falling For Changkong - Chapter 40

Kusumi Chiharu gets a message one day that he has been selected as a Monster Tamer, and he is prompted to select his first partner. He thinks little of the message until he receives a giant package the following day. He assumes it’s the porn books he ordered, but the huge box ends up containing the unconscious body of a near-naked girl! She’s a ghoul named Zonmi, who intends to fight beside him as his partner.

However, it turns out that other hot girls at his mostly-male high school are also magical entities, and Zonmi may not be the only one who wants to fight by his side!

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

He can ascend and descend with a thought.Enemies? A single word is all that is needed for obliteration.As Xuan Wu overlooks the world in his grasp, he asks himself—should he dominate, conquer worlds, create planets?Or should he play along just like an ordinary disciple?

Pei Xian, who looks like the green tea and white moonlight of Big Boss in the book, was forced by Zhou the First Gongzi to kill his child and send to the villain Big Boss as a substitute lover. Pei Xian would rather die than submit that he jumped from the building to his death.

When Shanghai’s Great White Shark Si Yang was only 28 years old, he died of illness and transmigrated as the cowardly and timid cannon fodder Pei Xian, airboned in confusion on the scene of the jump off.

Big Boss Gu Han: Come down, I want you and your baby.

Pei Xian▼_▼: 30 million free shipping, no check.

Zhou Kai:

In Gu Han’s book, the villain Big Boss was beaten by half of the book by the male protagonist’s “wisdom reduction aura” and eventually the Big Boss’s company went bankrupt and he became depressed. Now he is reborn with a system called “concern and care for villain’s IQ”, and Pei Xian is the system’s battery. Gu Han needs him to be around all the time to charge before using the system.

System task: Hold Xianxian’s little hand. System energy + 1

System task: Praise Xianxian, praise Xianxian beautiful. System energy + 1

System task: Please Xianxian and spend money on Xianxian. System energy + 2

System task: Make Xianxian bashful and coquettishly says hate. System energy + 2

Gu Han: Who am I? Where am I? What am I doing?

Green tea/white moonlight comes to the door: scram off substitute, this Immortal man has thought through to come back!

Pei Xian takes out a calculator▼_▼: Hello, please wait a moment. There are nine supercars, two listed companies and three mansions worth million all of which have been transferred to my name. Only the bankrupt goods belongs to you.

Gu Han picks up the scheming boy, turns around mercilessly and goes upstairs….

The sound of the bed collapsing came from upstairs.
