The Great Qin's Engineer Empress

When Zhao Xiaoxiao, a transmigrator, binds herself to the “Black Technology System” and becomes Zhao Ji, the discarded concubine of the Great Qin, all she wants is to survive with her young son, Ying Zheng.

But the System says, “Host, you must complete political intrigue missions and correct the course of history.”

From then on, she raises the future tyrant with her own hands and uses mechanical gears to change the tides of battle;

She also contends with Lü Buwei and Lady Huayang, exposing the fraud behind Qin Yiren's “adopted son” ruse;

And in a rift in time and space, she teaches political strategy through a “mother-and-son bickering” showdown with a young Ying Zheng.

“Mother, can the mechanical devices you taught me blow up Xianyang?” Three-year-old Ying Zheng clutches a gear assembly, golden light gleaming fiercely in his eyes.

Zhao Xiaoxiao smiles. “No rush. Wait until I've taught you how to use mechanical devices to kill your father and take the throne.”
