MTL - Save Uchiha, Start From Flipping the Table - Chapter 70

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.

The world is terrorized by the powerful Black Witch who has been sealed in the moon. Every ten years, the night of Hexennacht arrives and a chosen witch must battle the Black Witch in hopes of finally defeating her.

As the current decade’s Hexennacht approaches, a mysterious girl named Kagami Kagami arrives and meets Horinouchi Mitsuru, the daughter of the previous Hexennacht representative.

It takes place between Kyoukai Senjou no Horizon and the City Series, two other series by the author.

Violet skies, a world undergoing massive changes, a deficient moon, interlinking voids…
