1. Daizi was successfully processed and won the Kangxi Emperor Award. Ferdinand verbiest was the first science teacher of Emperor Kangxi. Proficient in astronomical calendar and good at casting guns. He knew Dai Zi had cooked his heart in such a short time, and he hated it. As a result, ferdinand verbiest colluded with the conspirator Chen, complained to the emperor and fell into the hands of the tortoise, which led to Dai Zi's guilty exile.

Second, Wei Dai was a very powerful figure in the Qing Dynasty. He not only passed the military law, but also knew astronomical algorithms. He is also good at poetry and painting. It can be said that this is a rare genius. It turned out that he was just a civilian. Later, he had to make some achievements in dedication and loyalty. Kangxi knew that he was very talented and appointed him as the president of the Hanlin Academy. Dai Hao did not let him down. He was an excellent genius, and later he invented some very powerful weapons, such as jewelry. But it was also because he was too smart that he was framed.

His newly developed cannon was quickly used by many people. Even in the later war with Wu Sangui, he used it to defeat Wu Sangui and achieved success. But at that time, Kangxi did not attach importance to the weapon invented by Dai Li. He even thought that the success at that time was because it was a situation that must be won. They believe that they will win the battle with or without Dai's invention. So when he rewarded Dai Li, he was sent to a remote place to be an official.

Fourth, Dai Zi is a Han nationality. Kangxi was too kind to him. After all, he can make such a powerful weapon. Perhaps this is why Kang Xining can believe that ferdinand verbiest won't believe Dai Zi.

The above details why Dai Zi invented 28 bursts of "machine guns" during the reign of Kangxi, and why he was later exiled to Ningguta.
