Early the next morning, I arrived at school. At the same time, I summoned Elder Jian and Elder Wu in order to produce tempered glass. The students studying weapon research and glass research all gathered together, and I began teaching them the principles of tempered glass and how to build a tempered glass workshop.
I explained every single detail with absolute clarity, covering the entire process from glass production to tempering. By the time I finished, it was already past three in the afternoon. I instructed them to inspect the tempering boilers, and told the other students to go and help out as well.
As for Yunkuai, she brought along her younger brother and the recruits she had gathered. It looked like there were over thirty thousand people. I could tell that out of these thirty thousand, more than twenty thousand were over the age of sixteen. Those under sixteen were basically fifteen, with only a handful being twelve or thirteen; presumably, these were the researchers. I also assigned them a shipyard site: previously, during the canal-digging days, two small lakes had been formed. Now, we could use the closer one for shipbuilding. The farther one would be used for training later on. Once the boats were built here, they could be sailed over there for target practice. After all, without accuracy, even the best heavy cannon was utterly useless. They also needed to practice maneuvering these pseudo-submarines—all of this required hands-on training.
