[Qin] Sharing a System with the Great Demon King of the Warring States

After transmigrating to the Pre-Qin era with a System for enriching the nation and strengthening the army, Qi Yan figured he had all the makings of the chosen one.

He was halfway through standing tall and proud when he got some bad news.

He had to share his System with a native of ancient times.

And that ancient was none other than Ying Ji, King Zhaoxiang of Qin, the notorious villain from countless Chinese textbooks, who seemed to have an endless battery life.

The only good news was that Ying Ji was currently no more than a lowly hostage sent by Qin to Yan. He hadn't yet ascended the throne or gained the power of life and death over others.

But it didn't take long for Qi Yan to realize that this one piece of good news was actually the worst news of all.
