Overnight, almost everyone in the entire palace knew that Zhang Menglong had been firing cannons in his room all night. They were all curious about what exactly this weapon, called the "Italian Cannon Plus," was.
According to Qi Xiu's speculation, this shouldn't be a conventional weapon, because he had seen Zhang Menglong's Star Watcher last time, and this should be a new type of weapon combining Cloud Armor Technique and Alchemy.
Zhang Menglong always managed to surprise people, so Qi Xiu and Qi Ning were also too excited to sleep that night.
The next morning, Qi Xiu and Qi Ning, along with You Ruo, blocked the doorway of Zhang Menglong's room. The clanging sound of ironworking had disappeared, replaced by crackling explosions, and occasionally some black smoke wafted out of the room.
Zhang Menglong inside the room was already at the final stage.
