I'm The King of Business & Technology in the Modern World - Chapter 168: Aurora Line Initiative

Su Ran, a music prodigy, woke up transmigrated into a book.

At that point in time, the main story arc in the book had already been completed. As a villainess female supporting character, not only did she need to take over the original owner’s pitiful life in poverty, she also gained an instant son right at his rebellious period.

Ten or so more years from then, the son would turn into a twisted, evil villain. He would appear in one of the extra chapters to pick on the male and female lead’s children.

***

Su Ran: Son, you shouldn’t be too outstanding.
Su Han: Why not?
Su Ran: ’cause you will be killed.

Su Ran: Son, would you like to learn music from me and become a zen, little fairy boy who only needs to drink dew.
Su Han: No, I want to go into business so I can support you.

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.
