Dragon King's Son-In-Law - Chapter 90: Duel!

The following were the talents of other cultivators: Divine Spiritual Root, Unique Body, Double Eyes, Divine Bones.

This was the talent of Chen Jingzhai: Bug Abuse.

Chen Jingzhai did not have any unique talent until he found out he could abuse bugs.

When he encountered a new martial art, he could instantly see the pros and cons and the weakness of the art.

When he fought, he could notice his opponent’s weakness and use that to his advantage.

When he brewed pills, he could abuse a special bug that allowed him to mass-produce high-quality pills.

Not only he could discover bugs while cultivating, but also in some special circumstances.

With the help of his new power, he began on a one-of-a-kind cultivation journey where he would become a legend.

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?
