Crusader King - Chapter 114: Endless Chain(15)

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?

Mr. Tycoon Is Actually the Father of My Child!

The sky and the earth are infinitesimal as a grain, and a life of peace is like the sea.

Lu Heng, who crossed over to the other world, found himself transformed into a huge white wolf, a mountain God of a remote mountain with a group of villagers under his rule.

In this strange and wild world, demons and giant beasts run rampant, and human order is almost non-existent.

These, however, are not what Lu Heng needs to think about. What he needs to think about now is how to tell this group of villagers that he does not need little girls.

Besides, he actually doesn’t want to be a God anymore…
