A Mistaken Marriage Match: Mysteries in the Imperial Harem - Chapter 76

Chen Yan travels between worlds, ending up becoming an honorable prince in a medieval fantasy world. Yet this world was not quite as simple as he thought. Witches with magical powers abound, and fearsome wars between churches and kingdoms rage throughout the land.

Roland, a prince regarded as hopeless by his own father and assigned to the worst fief, spends his time developing a poor and backward town into a strong and modern city, while fighting against his siblings for the throne and absolute control over the kingdom. Join Roland as he befriends and allies with witches and, through fighting and even farming, pushes back invaders coming from the realm of evil.

One day, I was given the mysterious power of Hwanmong.

Tang Long was brought to the Immortal Cultivation World by an immortal who noticed his affinity to wood and cultivation.
Relying on his amazing talent, became one of the five emperors of that world.
He failed his Heavenly Tribulation and had his soul scattered into pieces but one part found its way to Qin Haodong on Earth.
With his excellent medical skills, he became a divine doctor of traditional Chinese medicine and encountered the baby girl he made before going into the Cultivation World, whose mother was as pretty as a fairy. The little girl even asked him to find more lovers. What a cute girl…

The people of Earth have been summoned once again

Scientists document six extinction events in Earth's history, but none of them were as natural as they claimed.

Sylas and his family have been called back to the Browns, a family of billionaire elites with assets reaching into the trillions. He isn't sure what to expect until he touches a floating bronze cube that changes his life.

[Bronze City Stele]

[Status: Dormant]

[Time to Activation: 04:13:38]

Unfortunately, there's only one Stele and the Browns have already decided upon their candidates. If Sylas wants to control his own fate, he'll have to enter the Trial.

Now, woefully unprepared, and stuck in a world filled with the extinct creatures of Earth, he'll have to carve out his own opportunity... whether the Browns like it or not.
