Traveling Between Two Worlds: Ying Zheng Explores the Modern Era and Helps Great Qin Soar

[The protagonist is a young Ying Zheng, not a transmigrator, and not dying.]

After the Qin army suffers a crushing defeat at the Battle of Yi'an, the worried twenty-six-year-old Ying Zheng unexpectedly transmigrates two thousand years into the future. But since each transmigration takes him to a completely random place, this future emperor of all time is a little bit "unlucky."

First transmigration:

The moment he opens his eyes, he sees a chubby little kid with a runny nose about to give him "mouth-to-mouth resuscitation," while someone shoves "poison" into his mouth.

Second transmigration:

Mistaken for an NPC at Qin Shi Huang's Mausoleum, he's forced to work for free and unexpectedly helps avert a crisis.

Third transmigration:

Ying Zheng thinks he has transmigrated to a "paradise," only to discover that he's been made a male model!

Fourth transmigration:

Ying Zheng hears he can make a fortune, only to be dragged into a scam! When he gets cursed out for not knowing how to use a keyboard, he gets so angry that he leads people in a "rebellion"!

Fifth transmigration:

Ying Zheng swears he will keep his feet on the ground...

Though he's had a run of bad luck, Ying Zheng is suffering and enjoying himself at the same time.

With the history of later ages in hand, the first thing he does is bring Han Xin, Zhang Liang, and Zhang Han into his service, then execute traitors to the realm like Zhao Gao and Xu Fu.

With every transmigration, Ying Zheng brings back more advanced technology from later generations, and Great Qin is transformed!

A year later, Ying Zheng waves his hand and sends Great Qin's iron army against the six states. The six states stare at Qin's cavalry, dumbfounded...
