"Dr. Zhang is here." At the gate of Tuwa Fort, a Beiban soldier in charge of patrolling nodded and greeted Zhang Xinpeng, and began to search his whole body and the items he brought.

The reason why these Northern Barbarian soldiers were so polite to Zhang Xinpeng was because over the years, Zhang Xinpeng had not treated them and their families less. Zhang Xinpeng's medical skills are very good, and the fees are not very high, so many people remember his kindness.

After the Northern Barbarian soldiers routinely searched all the things on Zhang Xinpeng's body, they let him go to Tuvabao. However, Zhang Xinpeng really didn't have any other items on his body, that is, some medicinal materials, which they were used to.

But what everyone didn't expect was that this time, not all of the medicinal materials that Zhang Xinpeng brought into Tuvabao were used to treat diseases, and some could cause people to get sick.

These medicinal materials were sent to Zhang Xinpeng by the two mysterious people yesterday, Zhang Xinpeng has been a doctor for many years, of course he knows what these medicinal materials are used for.

Zhang Xinpeng also secretly admired in his heart, the person who dispensed the medicine was really clever, because this could cause a large number of people to fall ill. It looks very serious, but it's actually not a big deal, which is why he is willing to help these people.

After entering the Tuwei Fort, it was not so strict, Zhang Xinpeng was much freer, he deliberately tore a small hole in the paper bag wrapped in the medicine powder, and while walking, the medicine powder fell out of the paper bag and spilled on the road in the fort.

Checking the physical condition of some of the people in the fort as usual, prescribing some medicine to a few sick people, and instructing them to take the medicine and what they need to avoid when taking the medicine, all this is no different from usual, and the people in the dreg do not feel anything unusual.

But what no one knows is that Zhang Xinpeng looks no different from usual, but in fact, he is very nervous in his heart, it was still a cold day, and cold sweat was already oozing from his back.

However, Zhang Xinpeng has often entered Tuweibao for so many years, and everyone is already very familiar with him, so no one has ever doubted him at all, and of course no one has noticed his abnormality.

This time he stayed in Tuvabao for more than an hour, and for Zhang Xinpeng, it was like a year. When it was finally time to leave, he let out a long sigh of relief when he looked at the fort gate behind him.

"I've done what you told me to put things in, and it's not up to me to decide how much effect I can make." As soon as he returned to his room, he saw that the two people who had come to look for him were already sitting inside.

For these people to be able to avoid, all the people in the house appeared in their own rooms, and they could disappear unconsciously, Zhang Xinpeng knew that the identities of these two people were not ordinary, but he didn't inquire about anything?

"You just have to do what we ask, you can rest assured, we will not embarrass you until the last resort." When the two people in the room heard Zhang Xinpeng's words, they breathed a sigh of relief, and gave him some comfort, and then without waiting for Zhang Xinpeng to say anything, they jumped out of the open window and "flew" out, seeing that Zhang Xinpeng was a little dumbfounded.

In Daweibao, with a middle-aged woman experiencing dizziness, diarrhea and low-grade fever, a large area of disease spread rapidly throughout Daweibao. In just one day, forty percent of the more than 200 people living in the fort contracted this disease, and it has a tendency to continue to spread.

These Daning royal families, although they have not been valued much among the hundred barbarians over the years, but the existence of these people is not only a kind of pride for the Northern Barbarians, but also can be used as hostages, so they are still unwilling to let them have an accident.

Of course, the Beiban officials could not let go of the large-scale epidemic in Tuvabao. They sent a large number of medical officers, but they did not find out the cause of the disease, and even some of them were infected.

In the end, the Northern Barbarian Palace came to the conclusion that this was a sudden infectious disease, and if it was not treated in time, it might spread throughout the Northern Barbarian King City, and it was a big deal over there.

The Northern Barbarian King Heihan Naji was originally a generation of male lords, but when he encountered such a thing, he couldn't sit still. Immediately ordered the entire royal city to rejuvenate and gather all the doctors in the city to study the treatment of this disease.

Soon, almost all the doctors in Lingxing City, whether they were stationed for a long time or passing by temporarily, were gathered together.

After a simple medical test to determine the identities of these doctors, they were all admitted to Dawei Fort, and they were allowed to live in the fort and devote themselves to the treatment of this sudden disease.

What all the doctors didn't know was that the palace had already made a decision. In order to prevent the spread of the disease, if the disease is not completely controlled, all the people will remain in the fort forever. The palace even had a large amount of firewood and grass prepared, and once it reached the point where it was uncontrollable, the entire Dawei Fort and its people would be burned clean by a fire.

Ye Ying entered Tuvabao under this circumstance, and his identity as a merchant who went to the Beiban this time was originally a merchant who mainly used medicinal materials, and it was normal for him to know some medical skills, so he was not suspected by the Beiban.

When the doctors entered the fort, each of them was assigned one or two patients and asked them to treat them separately, because the disease was too real and too strange and too ferocious, so they had to use this disease to go to the doctor to see who had the most effective treatment.

Because the disease came very strangely this time, no one could judge the cause, so after entering the fort. The doctors were kept under the care of the doctors, who were allowed to move around the fort as they pleased, so that they could find out the cause of the disease.

Walking around the fort, the reason is that it is more like a farmstead, and all the people are dressed modestly, some are carrying buckets of water in wooden barrels, and some are holding hoes to loosen the soil in the field. Seeing everyone sweating like rain, if you don't know their identities in advance, you can't connect them with the children of the royal family in any way.

For the arrival of Ye Ying, an "outsider", the people here chose to turn a blind eye, they were still busy with the work in their hands, and it seemed that everything else had nothing to do with them.

Ye Ying quietly looked at these "peasants" coming and going in the fort, although he didn't know any of them, Ye Ying knew that most of the people here were related to him. The younger ones may be their brothers and sisters, and the older ones may be their uncles, if they are in Daning, they should all be nobles with high status.

Ye Ying had heard that when they were first imprisoned here, they had thought about escaping, but after they were caught, they were all severely punished without exception. Even some people who had no idea of escaping were implicated.

Of course, there are also lucky people, it is said that one of the younger brothers of the emperor Liu Heng, that is, the prince of Daning, once successfully escaped from Beiban and returned to Daning.

But the prince, who thought he had regained his freedom, realized when he returned to Jinling that he had only entered a more severe cage from one cage. After returning to Jinling, the prince was placed under house arrest and has never been seen since.

This matter was deliberately transmitted back by the Northern Barbarians, and the royal family in Tuwa Fort finally knew that Liu Gou, the king of Kang who ascended the throne in Jinling City, did not want them to go back at all for the sake of his position being stable.

Over time, these royal children stayed in Tuvabao with peace of mind, and even married and had children here. Year after year, I have lived this hopeless life, and the spirit of the year has been wiped out.

The poison in Tuva Fort was prepared by Ye Ying, and he specially asked Qi Jiao and Shan Fu to hand it over to the doctor Zhang Xinpeng, and he scattered it in this fort. This poison looks very dangerous, but it is not very harmful.

After entering the castle, Ye Ying did not immediately sprinkle the antidote to remove the poison, because he still needed to stay in the castle for a while.

At the fourth watch, it was the darkest time of the night, and it was also the time of the day when everyone slept the deepest, and no one noticed that a black shadow suddenly came out of the house. Outside the house, a few Northern Barbarian soldiers were patrolling, but they were not able to spot the black shadow.

The speed of the black shadow was very fast, and as soon as he came out of the house, he quickly rushed to the roof, and under the cover of night, he headed in the direction of an artificial earth hill behind the Tuwa Fort.

The patrolling soldiers were also very serious, they carefully inspected every corner of the fort, but these patrolling Beiban soldiers never dreamed that someone was flying over their heads.

It didn't take long for the shadow to reach the dirt hill and stop between the tombs built on the dirt hill.

This black shadow is Ye Ying who finally sneaked into the Tuwei Fort, the Tuva Fort is not big, it didn't take long for him to find out the location of the cemetery, and he quietly came here in the dead of night at this time, when everyone was falling asleep.

Judging from the size and location of the tombstones, the place in the center of the cemetery must be the tombs of two emperors and important members of the imperial family.

Although it was dark, Ye Ying, who had good eyesight, quickly found the tombs of his grandfather Liu Ji and father Liu Huan, although he did not have much affection for these two incompetent emperors, but after all, they were his relatives, Ye Ying still walked over and kowtowed a few times in front of the tombs of the two.

Catching the faint starlight, Ye Ying finally found a few sons of Daning Empress Zhu Lian on a tombstone, and his tears flowed out at once. This great woman, in order to keep her child, endured humiliation and burden, and finally entrusted the infant Ye Ying to the fierce eagle Ye Shuai, she chose to break herself.

It is said that Queen Zhu's behavior not only made the people of Daning sigh, but even the Beiban as a hostile country was moved, and they gave Zhu Lian a grand burial, and even Heihan Naji, who was the king of the Northern Barbarians, was personally present.

"Mother, the child is not filial, I have only come to visit your old man for so many years, and the child has kowtowed to you." Because he didn't dare to light incense candles, Ye Ying had to find a few sticks from the side, and inserted the incense candles in front of his mother, and after kowtowing a few times, he knelt quietly in front of the tomb, tears falling on the ground on the side with his cheeks.

Time passed little by little, Ye Ying suddenly woke up from his immersion, a lot of time had passed, and he knew that it was time for him to leave. If you delay for too long, you will be found and not to mention, and it will affect the brothers who are still in the inn.

Despite his reluctance, Ye Ying stood up decisively, turned around and prepared to return the same way, but the next moment he was taken aback, because there was actually a person standing behind him.
