Great Qin: From Korean Spy to Great Qin Chancellor

Transmigrating into the Qin dynasty as Zheng Guo, a guest official.

From the start, he receives an order from the King of Han to destroy the Zhengguo Canal, which is nearing completion.

Faced with the King's threats, Zheng Guo decisively lays his cards on the table, handing Ying Zheng the royal decree and throwing his lot in with Qin!

He even offers Ying Zheng a plan: turn the expulsion order against its authors and win over the members of the Ying clan.

Qin soon sends its troops against Zhao, beginning the campaign to unify the realm.

When Zheng Guo persuades the acting governor of Nanyang to defect to Qin, and Qin's iron cavalry enters Xinzheng, the capital of Han, the King of Han regrets everything...

"Zheng Guo was hiding his true abilities all along..."

"I sent you to Qin under the pretense of building a canal, to weaken Qin. I never expected you to be so gifted..."

Guo Kai even promises Zheng Guo: "Help me make a fortune, my lord, and at your command I'll open Handan's gates and welcome the Qin army into the city!"

Li Si is dumbfounded: "I thought Zheng Guo was a simpleton who only knew how to build canals. I never expected him to take my place as prime minister..."
