After arriving on the street, Qian Ruoyu looked around again and found that more and more people on the street had symptoms of infection.

Qian Ruoyu felt surprised inwardly. After all, if this was true, it meant that many people on the street had already fallen into the incubation period.

Qian Ruoyu couldn't guess how long the incubation period of this plague was, but the outbreaks in multiple places also indicated certain problems.

The more this happened, the more Qian Ruoyu felt helpless. He could not accomplish this task by relying on his own strength. Therefore, Qian Ruoyu decided to look for the Nine Gates Admiral as soon as he finished studying this medicine. Perhaps his power could help a little. Qian Ruoyu also wanted to find Chu Mobai.

After thinking about this, Qian Ruoyu just took a quick walk on the street, and then immediately returned to the palace with the golden lotus. At this time, the gate of the palace was completely closed.

After all, the palace had been completely closed off in accordance with Qian Ruoyu's request. Qian Ruoyu and Jin Lianhua almost climbed over the wall to get in, and the butler Wang behind the gate looked on full alert.

Butler Wang obviously realized from Qian Ruoyu's punishment that this matter was of great importance. Butler Wang did not delay any further, but instead looked serious.

Seeing the serious look on Butler Wang's face, Qian Ruoyu felt much more relieved, and then she took Jin Lianhua back to the old place.

Just after returning to the cube, Qian Ruoyu glanced at the golden lotus and said to it.

"You should have a good rest now. I am also going to take a rest. We will have other things to do after we wake up."

After hearing what Qian Ruoyu said, Jin Lianhua did not refuse, nor did she make any excuses. Instead, she nodded and went back to her little room.

After watching Jin Lianhua go back, Qian Ruoyu also returned to his courtyard room, closed his eyes, and entered the laboratory.

Qian Ruoyu put the obtained ** into a test tube and began to analyze it.

After a brief analysis, Qian Ruoyu was immediately certain in his mind that this was obviously a deeply hidden plague, and it was impossible to tell from the data where it was, so how much more was going on behind it?

Afterwards, Qian Ruoyu continued to analyze and take it apart, trying to find the antidote. For Qian Ruoyu, only finding the antidote would make him feel a little relieved.

Qian Ruoyu knew this kind of thing better than anyone else, and knew there was obviously no way to help unless he could find some help.

But in this era, Qian Ruoyu does not trust any doctor and only trusts his own laboratory.

Qian Ruoyu divided the obtained data into different instruments. It was only a small amount, but Qian Ruoyu had already started analyzing it.

Only with experimental data can the problem be solved.

After putting the experimental equipment away and letting him conduct his own research, Qian Ruoyu left the laboratory and returned to the palace.

After resting for half a day, Qian Ruoyu returned to the laboratory and took a quick look at the experimental results.

The country was safe, and the results came out. Qian Ruoyu took a look and was surprised when he saw the experimental data, because this was indeed a plague, and the experimental equipment had actually shown the medicinal materials needed for the plague.

After all, there is no way to use modern medicines, and with so many people in the entire capital city, if modern medicines really need to be used, it would be impossible for Qian Ruoyu's laboratory to produce such a large number of medicines.

It was at this time that Qian Ruoyu saw three words in the experimental data: Trichosanthes.

As soon as Qian Ruoyu saw the trichosanthes, he immediately remembered what happened in his previous pharmacy. Could it be that the trichosanthes that person bought was prepared for today?

And at this moment Yan'er suddenly ran in and said to Qian Ruoyu.

"Your Majesty, several doctors have come to the back door of our palace, hoping to see you. They also said that they have something very urgent and hope to find you!"

After hearing this, Qian Ruoyu just nodded slightly, and followed Yan'er to the back door of the palace.

There were indeed five or six doctors standing at the back door of the palace, and among them there was a very old one who was talking to him on the street.

At the back door of the palace, in addition to these doctors, there were also several people led by Wang's steward. They all held sticks in their hands, obviously refusing these doctors to enter the palace.

Qian Ruoyu also saw that Butler Wang was indeed very serious in strictly following his words, so Qian Ruoyu nodded slightly at Butler Wang.

"Butler Wang, you did a good job. Now you can go back first."

After hearing what Qian Ruoyu said, Butler Wang naturally nodded immediately, and then left the back door of the palace with his people.

After seeing Qian Ruoyu, they were shocked. They never thought that Qian Ruoyu was actually the princess. Qian Ruoyu was really puzzled. She did not reveal her identity on the street, so how did they know and find her?

Just when Qian Ruoyu was wondering, the old doctor finally spoke.

"Princess, although we don't know you and have never followed you, a doctor once saw you nearby. And seeing that you behaved very well and were dignified and elegant, it is obvious that you are not an ordinary person. That is why we tried to come to the palace to meet you."

"I didn't expect that you are here, Princess. It's really presumptuous of us, but there are some things that we must find you for. Only you can help us!"

Qian Ruoyu nodded slightly, and then invited several people to the palace. After all, they were all doctors, so Qian Ruoyu did not think that they might be infected with the plague.

Then they were invited into the side yard and given tea and snacks, which made the doctors feel flattered. Even the old doctor in the middle was shocked.

The old doctor said.

"My Lady Princess, after our investigation, this is clearly a plague. And if we want to cure this plague, it may not be a simple matter. It requires a lot of medicinal herbs to help."

Qian Ruoyu nodded slightly to signal him to continue.

"But one of these herbs is extremely rare, especially in the capital, and almost no one can find it!"
