Shao Qingyuan's pupils constricted slightly, and his expression became thoughtful.
Gu Yundong secretly looked at him and did not disturb him. After a while, he heard him say, "There's a way to prevent smallpox, but this method can't guarantee that nothing will go wrong. According to you, if the person with cowpox is fine, can't we change the smallpox to cowpox?"
Gu Yundong pursed his lips. Ah, ah, ah, ah, ah, ah. I knew it. He really thought of it at once.
Gu Yundong's eyes lit up and she said in surprise, "That's right. Why didn't I think of that? If it succeeds, will we not have to be afraid of this illness in the future?"
Shao Qingyuan's eyes were also shining. If that was the case, this was a huge matter that would benefit the country and the people.
His hands trembled slightly, and he was a little tempted.
For the first time, he had such a strong desire to do something.
