The Great Qin: Stop Pretending, Your Father, I Am Qin Shihuang

Novel Summary
Zhao Lang woke up and found himself in the Qin Dynasty.
Fortunately, the family is relatively wealthy.
Just counting the time, Da Qin only has three years of lifespan, so Zhao Lang summoned the courage and said to his cheap dad who only came back once in a few months,
“Father, the First Emperor will die in three years, and Da Qin will die. When the world is in chaos, let’s prepare for rebellion!”
Daddy Cheap was stunned for a moment, then nodded in agreement.
Zhao Lang suddenly became fashionable in education and trained new troops.
Just when he was full of wings and ready to fight for the best in the world.
The cheap dad suddenly came to him,
“Don’t pretend, it’s a showdown, your father, I am Qin Shi Huang.”
