In the evening, Yun Shengtian and Professor Zheng finally arrived at the checkpoint leading to Fancheng.

In the past, there were no checkpoints here, probably because of the epidemic in Fancheng, all roads leading from Kyoto to Fancheng were blocked, and the only way to do this was to set up checkpoints to intercept ordinary pedestrians heading to Fancheng.

When Professor Zheng and his entourage arrived at the checkpoint, Yun Qingyin immediately urged the horse forward, "This is the doctor sent by His Majesty the Emperor to support Fancheng, this is a pass order!" ”

Yun Qingyin took out a piece of bright yellow silk, and Yun Shengtian looked at it from a distance, and could vaguely see that it was covered with a big seal.

The soldiers at the pass glanced at it, and immediately returned their hands to Yun Qingyin, "It turned out to be the divine doctor who supported Fancheng, please!" ”

Immediately pull open the fence and stand respectfully on the side of the road.

He walked forward for another half an hour and arrived at the bottom of Fancheng.

Yun Qingyin urged the horse over and spoke to Professor Zheng in the carriage, "Professor, shall we go into the city now, or will we stay outside the city for one night and enter the city early tomorrow morning?" ”

Professor Zheng stepped out of the carriage and glanced at the guards on the city tower, "Can you contact the defenders here?" It's best to get a sample of the disease, and after we study it, we can figure out what the situation is inside, and it's not too late to go in. ”

Everyone knows that even if Professor Zheng is from the Holy Land, he is a mortal, not a saint, and it is impossible for him to really sacrifice his life for the sake of people who don't know Fancheng.

Yun Shengtian felt that Professor Zheng was understandable in doing so.

After all, Da Chu has no kindness to Professor Zheng, and if Professor Zheng hadn't been for his own research, he wouldn't even know where Da Chu's Kyoto is, let alone a small Fancheng.

To put it bluntly, Professor Zheng came to Dachu with his own purpose, and when he came to Fancheng, I am afraid he also had his own ideas, and it could not be because of the emperor's trust.

As he was talking, there was a commotion on the city tower, and the two defenders grabbed an old man and were scuffling on the city wall, "The old man is here to heal, not to wait for death!" Even if you have the emperor's holy decree, you can't stop the old man from going out of the city to find medicine! ”

A person who looked like an official next to him sneered, "Even if you are the imperial doctor, when you get here, you have to listen to my instructions!" Take it back! If you dare to climb the city wall one step further, you will be killed! ”

"This is? ......" Professor Zheng asked Yun Qingyin.

Yun Qingyin was noncommittal, as if he hadn't heard, and looked up at the city wall, trying to get in touch with it.

Everyone looked at the group of people above, and saw that the old man broke free from the two soldiers, ran to the battlement of the city wall, and shouted at Professor Zheng and his party, "You are also doctors, right?" Hurry away and stay away, the plague here is ...... at all."

Before the old man finished speaking, the person who looked like an official had already kicked at the old man, "Old thing! That's how you want to get out? Lao Tzu will give you a ride! ”

As the words fell, the old man rose into the air and flew out of the city wall.

No one could have imagined that such a thing would happen.

Yun Sheng glanced at Yun Qingyin, this fairy-like eldest sister has always been kind-hearted, if she comes to the rescue, with Yun Qingyin's kung fu, it is not impossible.

It's just that.

Yun Qingyin turned his head indifferently, not even bothering to look at it.

Yun Shengtian had come to investigate the plague, and the old man was the best person they were looking for.

Yun Shengtian stood up on his horse, one took off into the air, caught the old man in mid-air, and then spun around, counteracting the inertia of the old man when he landed, and easily fell to the ground.

Yun Sheng saw that the old man was spitting blood, presumably suffering from internal injuries, and hurriedly turned on the scan.

After checking it, Yun Shengtian was stunned on the spot.

Professor Zheng and a few others had already gotten out of the carriage and came around, "Holy Tilt, how is it?" ”

Yun Shengtian stood up, "There is still a breath, if the professor has anything to ask, hurry up and ask!" ”

Professor Zheng had already put on masks in the carriage, wore disposable gloves on his hands, and wore protective clothing.

At this time, Professor Zheng stepped forward and said, "Holy Tilt, you didn't do anything to protect yourself, hurry up." ”

Yun Shengtian said softly, "Professor, I don't think this person is an infectious disease. ”

"Oh? Let me see! Professor Zheng took out his stethoscope and squatted down in front of the old man.

The old man opened his eyes all of a sudden, grabbed Professor Zheng's hand, "Go far!" Don't come near me! I'm going to die! Fancheng is finished! Fancheng is about to become a dead city! ……”

Before he finished speaking, the old man spat out a mouthful of blood and died of exhaustion.

Professor Zheng saw at a glance that there seemed to be something in the blood spit out by the old man, "Yanan, hurry up and collect a blood sample!" ”

The blood was densely packed, like insect eggs.

Professor Zheng picked up a wooden stick from the side and played it back and forth in the old man's blood.

"What is this? ......" Professor Cheng said to himself.

Yun Shengtian had already taken a picture of the blood that the old man spit out just now and entered it into the computer, and the result had already come out, and what the old man spit out was insect eggs.

And the old man's stomach is a Gu worm, and it has been multiplied for several generations, and the old man's body has long been hollowed out.

This kind of Gu worm, according to the records on the computer, only needs to find out the female Gu worm.

If you can't find the female Gu worm, you want to detoxify the person who is in the Gu alone, not to mention the physical strength, if you miss, not only the rescued person will die instantly, but even the healer will be counterattacked and poisoned to death.

It's just that Gu poison is not an infectious disease, and the person who goes under Gu targets someone, or a certain group of people, through water sources, or food, to poison people.

Since this kind of Gu poison is man-made, she is helping the people here in Fancheng to get out of danger, and there is a second and third Fancheng waiting.

If you don't find the people behind the scenes, with her and Professor Zheng, even if you are tired to death, you won't be able to turn the tide.

Yun Shengtian stood silently to the side, not saying anything.

Gambling on the people of the whole city, who is such a big deal.

Yun Shengtian didn't want to think about this kind of thing, the matter of detoxification, she didn't want to get involved, she didn't want to be unable to save people, she had to make a fuss.

When the people on the city tower saw Yun Qingyin and his party, they took the initiative to greet him, "I don't know who is down there?" ”

Yun Qingyin got off the horse, clenched his fists and said, "It's General Hu above?" Below, the Divine Doctor of the Holy Land came to investigate the plague. ”

The one above said, "General Hu is sick, and below is Adjutant General Zhao Liang." Since he came by holy decree, he will send someone to open the gates of the city! ”

When Yun Qingyin heard this, he hurriedly said, "General Zhao, slow down!" ”

She glanced at Professor Zheng, looked up and said, "Thank you, General!" We listen to the command of the divine doctor of the Holy Land, and if we need the general to open the city gate, we will disturb the general below. ”

Zhao Liang, who was above the city tower, snorted in his nose and turned to leave the battlement.

Yun Sheng's cold eyes glanced at Yun Qingyin.

In the end, I have been following my father for many years, and I have not learned the skill of arranging troops, but I have learned ten percent of the cunning of soldiers.

Yun Qingyin is not stupid, she had to take the guards to escort Professor Zheng and his party over, she had already risked her life, at this time, if Professor Zheng and his party insisted on entering Fancheng, they must have a means to protect themselves, and she could also be blessed with the guards following behind.

At present, Professor Zheng does not advocate entering the city, which is exactly in line with Yun Qingyin's intentions, and when he returns to Kyoto and sees the emperor, he can also make a deal.

Yun Sheng sneered coldly in his heart, stood aside, and said nothing.

She was like an outsider, watching Professor Zheng do a few busy jobs, and Yun Qingyin and his party pretended to be.

Professor Zheng's side, by the time Yanan got the glass from the car to collect blood samples, the old man's blood had already coagulated.

"This? ......" Yanan looked embarrassed.

Despite this, at the suggestion of Professor Zheng, the samples were collected and sent to the carriage.

The man held a plastic bag in his hand, like the kind of corpse in the last days, and said to Professor Zheng, "Why don't you bring the corpse back?" ”
