"Emperor, why don't you let Eunuch Qian try it out first?" Gu Chengrui hesitated for a moment and suggested.
Although he was confident in the cowpox vaccine, just in case, he still felt he should get it after he thoroughly approved it.
Moreover, although the country seemed calm now, the undercurrents were surging, so it was better to be careful.
"Emperor, let Eunuch Qian go first." Guard Chu echoed.
"How about this, Chengrui? You go back and rest well. Tomorrow, I will select a group of people for the vaccine. At the same time, let the people from the Imperial Academy of Medicine follow and observe.
"Let's see if there's any difference."
"Alright. I will take my leave first." After Gu Chengrui finished speaking, he looked at Guard Chu and said, "I'll have to trouble Guard Chu to protect that cow."
"Don't worry, Lord Gu." Guard Chu smiled.
Gu Chengrui nodded and turned to leave the palace.
