The Villain's Wife - Chapter 861 Lilian herself

This story revolves around a boy who was sent to a dark, mysterious parallel world in the body of his beautiful senior sister known as Lily. The lone girl ran into the night parade of a hundred ghosts the very day she arrived; seeking survival amongst the warrior’s dispute in a chaotic world, and forging her own demon sword! This is an unimaginable other world adventure!

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?

Yu Chi transmigrated to a world covered with savage, barren lands, where more than 10,000 races fought to ascend to the top. He began his life in this world in imprisonment.

While the others had completely forgotten about his existence, he took out a bamboo stick that he had been carrying with him since his previous life.

The souls of ancient divine beasts could be found in various savage lands and rivers.

His bamboo stick could communicate with these ancient souls.

When he fished at the Death Sea of Hades, he got the voice of Naga Siren.

When he fished at the Ice River of Skeletons, he received the attack power of Blobfish.

When he fished at the Lake of Grotto-Heaven, he obtained the golden eyes of the Five-Talon Divine Dragon.

When he fished at the Cliff of Hanging Candles, he acquired the fire of the Nine-Tailed White Fox.

In the blink of an eye, millions of years had passed. Deities and pet beasts from various corners of the world came to congratulate Yu Chi on his wedding.

A prominent figure couldn’t help but ask, “Why are you so terrifying?”

As Yu Chi stared at his gorgeous wife, the memories of him fighting millions of devils in the Underworld flashed in his mind.

He then smiled and replied, “There’s nothing I can boast about. I was just lucky.”
