Ying Zheng, Emperor of Great Qin: Immortality

Ying Chen transmigrates to Great Qin and becomes the Ancestral Dragon's seventh son.

He also awakens an Emperor System!

His first mission: save the empire from collapse!

But what he doesn't know is that the Ancestral Dragon, Ying Zheng, has awakened a System of his own!

An Investment Feedback System!

He chooses nine princes to put to the test. Whenever one of his investments comes in first, the System rewards him with a corresponding amount of lifespan, based on the scale of the test!

It even gives him a Potential Ranking!

[First: Prince Chen; System assessment: one in ten thousand!]

[Second: Prince Fusu...]

[...]

[Ninth: Prince Huhai; System assessment: recommendation: **!]

Across test after test,

Ying Chen invents gunpowder and the Zhuge repeating crossbow, presents the grace edict, wipes out the remnants of the six kingdoms, and brings the Hundred Schools of Thought to heel...

In the end, Ying Zheng, who had invested in Ying Chen all along, suddenly realizes:

He has become immortal.
