Tang Jinghong looked at the maps carefully again and did not find any flaws, but he still needed to verify them. "How much do you know about the crossbow?"
Tong Yujie said, "Tang Jianying, one of the ten trusted aides of the Lord of the Northern Border, is in charge of making crossbows. The modified crossbow was made two years ago, and the Lord of the Northern Border ordered that it be kept a secret. No one knows much about it."
What Tang Jinghong wanted to know the most was, "Who is the person who modified the crossbow?"
The topic of the modified crossbow was extremely sensitive in the Northern Border. No matter who it was, if they talked about it, they would be killed without mercy. During this period of time, Tong Yujie had been asking around and was almost discovered.
"General, only the Lord of the Northern Border knows about this. With my status, I can't find out. I've tried my best to find out but to no avail."
