There Is A Huge Problem With My Achievement System - Chapter 4

Mu Jingzhe transmigrates into a book filled with sweet, doting love to become the useless supporting character who serves as a foil to the female lead. She also becomes the stepmom of five kids to her recently deceased husband.

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?

Having been reborn, she takes one glance at her ridiculously handsome husband and wonders if she had suffered from brain damage back then—she had actually demanded for a divorce with him. Repeatedly!

Jiang Yining was transmigrated to a cultivation world and became the master of the Tianyan Sect.

Unfortunately, the sect was broke and he only had three disciples. Just as everything was about to fall even further apart, he received the Golden Finger.

To make it even more interesting, the Golden Finger was an idle cultivation game that Jiang Yining had played in his previous world.

[Welcome back, long-time player. You will inherit your old account that has been idled for a million years.]

From the game, Jiang Yining could receive martial arts, resources, fates, buildings, skills, and even spiritual roots from checking in and completing quests.

He vowed that he would use the rewards to grow his own sect.

In the world of cultivation existed prestigious families, sects, kingdoms, and even celestial sects. Everyone’s goal was to ascend to a celestial being.

However, years later, Jiang Yining and his Tianyan Sect sat on the Long River and looked down at the people still struggling in the celestial realm.
