Time travel to a small city lord at the end of the Warring States Period. You have no more than a hundred soldiers, and you can't have enough food and supplies for a month. What's even more desperate is that you are surrounded by three major forces: the Hu cavalry in the north are ready to go south to plunder, the Qin army in the south is eyeing you, and the rogue bandits in the east also want to get a share of the pie. People in the city were in panic, and riots could occur at any time.
Fortunately, you have awakened to the modern city system. As long as you defend the city, you can redeem elite soldiers, advanced weapons and future technology. From bows and arrows to artillery, from wooden fences to steel walls, your city is getting stronger every day.
Your goal: Use this city as a springboard to gain a foothold first, then annex the princes, and finally compete with Qin Shihuang. But there is only one city at the beginning, but your opponents are all heroes. Can you counterattack in the cracks and rewrite history?
