Now Ye Chen and Yizi packed their clothes and came in, naturally they didn't plan to come out again. After driving inside, Secretary Liu and a person in charge of Dahe Hospital came to pick up Ye Chen.

Now Yizi's true identity has not been exposed, in front of other people, just admitting to be Ye Chen's assistant and translator.

Yizi can speak Chinese and Japanese. With her interpreter, Ye Chen must be much easier to contact those Japanese doctors.

The person in charge of the Yamato Hospital arranged for Ye Chen and Yizi to live in a room. It turned out to be a separate high-level ward, but now all other ordinary patients are transferred to other hospitals, and now it’s left here for the time being. The doctor who came next time stayed.

After Ye Chen and Yizi put the clothes in this room, Ye Chen went to the ward of the first Chinese old man who was infected with the plague.

Now besides this old man, there are also his wife, his son and daughter-in-law.

The situation of the elderly is still quite serious, but the situation of the elderly's family members has been significantly reduced. Ye Chen asked about the situation of the elderly's family.

The old man’s sons can express it in awkward Mandarin because these people themselves speak Chaoshan dialect, but Ye Chen doesn’t understand Chaoshan dialect. They speak Mandarin with a strong local accent, even when they come to Japan. I have lived here for a long time.

"Did your father talk to you about anything before he became ill?"

Ye Chen asked about the eldest son of the old Chinese man.

"I didn't pay much attention either. My dad usually goes back to rest after cleaning up in Chinatown, just three times a day."

Said the old man's eldest son.

"Then before he fell ill, have you heard of what happened to him?"

"It seems that I heard him say that he was bitten by something and asked if he should get a rabies vaccine?"

"Is the old man bitten by a cat or dog?"

There are many cats and dogs here in Japan, especially in Chinatown. However, they are not the stray dogs and cats outside, but some people raise them.

In this regard, Ye Chen discovered that those people in Japan may have more cats and dogs than in China.

"It should not be a cat or dog."

Said the old man's eldest son.

In fact, he was not very clear. His father only told him at first, but later heard that he did not go to the hospital for a vaccine. The main reason was that the price was too expensive and the old man could not afford the money.

Moreover, the old man felt that he should have no problem.

However, now that Ye Chen heard it, he felt that there must be a problem in it. The old man was either infected by something else or infected with this plague after eating something. After all, it is impossible to get this plague for no reason. Viral.

When Ye Chen was about to go to see other patients, the wife of the Chinese old man suddenly said: "Doctor Ye, I remember my husband seemed to say that he was bitten by a rat that sprang out when he was cleaning in a trash can. !"

There are many rats in the urban villages in China and they are very fat.

In Chinatowns in other countries, Ye Chen has also seen a lot of fat rats. They would come out at night to find food, especially in those trash cans, where they might rummaged for trash to eat.

"Did your husband be bitten by a mouse? Where?"

The old woman seemed to remember that her husband had mentioned it to her, but the old man did not dare to talk to the company for fear of being fired from the company.

"It seems to be bitten to the foot."

After Ye Chen heard it, he hurried back with Yizi to check the old man's feet.

After lifting the old man's trousers, Ye Chen carefully checked the skin and green veins on the thin and thin feet. After so many days, it was more difficult for Ye Chen to find the remaining wounds on it.

However, if the old man was bitten by a rat and then contracted this unknown plague, then it is very likely that the plague itself may be carried by the rat itself, or the rat may have contracted it from other sources. The virus, then spread to humans.

Now Ye Chen doesn’t care about this. Instead, he called Han Wensheng, the brother of Han Wenshan from Chinatown’s Fuqing Gang, and asked him to ask people to catch as many mice as possible in Chinatown. It’s best to live, but be careful not. Don’t get in close contact if bitten by those rats.

Han Wensheng didn't know what Ye Chen asked him to do to catch mice, but now he can only ask people to catch them.

There are many restaurants and restaurants on Chinatown. There are all major Chinese cuisines. So many consumers here usually pour the leftover food directly into the bucket of the back kitchen and then clean it out at night. It can fatten up many rats.

The mice here are different from the domestic mice. The mice here have sharp heads and very cunning, but they are very courageous and are not afraid of people at all.

Usually the Japanese government will let people clean up those mice regularly. The mice can't be killed. Moreover, the environment of the Chinese restaurants is different and it is easy to raise the mice.

It's night time, but it's not the time when rats are out on a large scale, they will appear in the early hours of the evening.

Now Ye Chen called Han Wensheng and asked him to ask someone to catch a few mice tonight, and then someone would pass by and take those mice away.

After Ye Chen finished the phone call, Ye Chen could be sure that if there was a plague virus similar to that of an infected person in a mouse.

Then it can be proved that the old Chinese man was probably infected by the plague virus carried by these rats.

As for how these mice carry this plague virus?

Then other people are required to investigate.

However, Ye Chen knows that as long as we investigate how the mice carry the plague virus, then the source of the plague virus can be found soon, and even the way the plague virus spreads this time, so that many people can stay away from this plague. Viruses, find effective treatments as soon as possible.

After Ye Chen and Yizi saw a lot of patients, at around ten o'clock in the evening, after Ye Chen and Yizi returned to the separate high-level ward, Han Wensheng called and said, "Doctor Ye, I'll let someone arrest you. There are a few mice, fat and big, they are delicious for hot pot."

"These mice were not caught and eaten. These mice may carry the plague viruses. I let you catch them. I want people to confirm whether they really carry those plague viruses."

"Doctor Ye, I just joked, who would dare to eat these mice. But, I don't know, how is my elder brother now?"

"Your eldest brother is in good condition, and his condition has stabilized. I now let someone go over and take those mice you caught."

Ye Chen called Secretary Liu and asked Secretary Liu to contact the Japanese side, and then let the Western medical researchers in Japan prepare to go to the entrance of Yamato Hospital to take the mice to the laboratory for research.
