Daqin Engineering Corps

Shen Bing, a mechanical design major, traveled back to the Qin Dynasty.
He just wants to survive simply. Who would have thought that this is a life-or-death world, and if you don't make progress, you will be eliminated.
The helpless Shen Bing could only arm himself with inventions.
The improved trebuchet made it impossible for the enemy to touch even a hair at double range, and he would knock over the opponent while he was lying down;
Design a ladder, and dozens of people swarmed up, climbed over the wall, grabbed the flag, opened the city gate, and captured another city;
The moat, urn city, etc. were a piece of cake!
So...
Destroy the six kingdoms and conquer the Huns!
Peace the Western Regions and conquer Rome!
Zeguo Jiangshan enters the battle map, one general will achieve great success!
