Meanwhile, at Zhenyuan Pass, 20 miles away, the battle was extremely fierce. The army of the Northern Yuan Dynasty had traveled from afar and didn't rest, directly attacking the pass.
This Zhenyuan Pass had four huge contraptions capable of firing spears, which could unleash over a hundred spears at once, and their range could be adjusted. Ziwen had asked Mingyu for help when building this pass. They had invited a master of machinery from the capital, and it took half a year to build these devices. Eight were made in total, with four placed in Xizhou City. The power of these machines was extraordinary.
The Northern Yuan army sent 30,000 troops this time around. One could see the vast expanse of soldiers outside Zhenyuan Pass, advancing and retreating in order. It was clear they were well-trained sergeants.
