The Crippled Bigshot's Little Ancestor Is Too Cool - Chapter 67 - Favours

The price for saving the world is the right to rule it. After saving a faraway land, Lyn Rivers was cast back to Earth. Wanting the admiration, prestige, and glory of saving that realm, she forced her way back. But she was forgotten, and someone else claimed credit for her deeds. Now, with the power of a deity of destruction, she desires nothing more than to claim her place in history. To do that she will conquer dungeons, make alliances, destroy kingdoms, and build an empire. After all, why ruin the world when you can bend it to your will?

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?

Shu Shi has been the villain in the book from time to time and had to play by the plot in order to become the protagonist in another book.

According to the plot, he must eventually die under the heroine’s sword.

When he was about to die, Zhan Qingchen stood up with her sword and asked him what his last words were.

Looking at the indifferent beautiful face, Shu Shi, who was lying in a pool of blood, was timid.

He pulled Zhan Qingchen down hard and gave her a forced kiss!

“This is the last time we meet anyway!”

Shu Shi closed his eyes in satisfaction.

Zhan Qingchen hated men so much and now her chastity had been taken away! This kiss was the best revenge for his nemesis!

After this he would be reincarnated and become the real ‘Favored son of heavens!’

But what Shu Shi did not expect was that Zhan Qingchen actually used the treasure to save him from the gates of death!

Now that they were sitting in silence, the atmosphere had become extremely awkward.

Zhan Qingchen: “Explain, why did you kiss me?”

Su Shi: “…”

He was an addict, a loser, a despicable human being.
