Everyone else was unaware of what had happened, only Xu Shiba was inconsolable no matter what, leaving Xu Wenwu with no choice but to take her back, while Wei Yuan and Yu Zhizhuo went to inspect the latest artillery pieces.
There were two types of cannons in this batch, one of which was massive, weighing tens of thousands of catties, capable of firing projectiles up to fifteen miles away. Yu Zhizhuo also handed a Jade Paper to Wei Yuan, saying, "The ranges and impact points are all on here."
The Jade Paper detailed the angle of the cannon's muzzle and the corresponding range, in addition to marking the deviation of the impact point starting from five miles out. At the extreme range of fifteen miles, the deviation could reach up to one mile.
"Have they all been tested?" Wei Yuan asked.
"Those beyond five miles have been tested. The deviation within five miles is insignificant; we can just follow the calculated trajectory directly."
