Looking at the weak doll in front of her, the old lady shed tears excitedly, this little doll was so touching the old lady's heart, making the old lady so heartbreaking, is it, did she disappear in front of her like this?

Then, something that made her even more heartbreaking appeared, her eldest son also appeared Yang Heng, at that time her heart was desperate, is God going to take in her own family, although there is still a son and a daughter of her own, but they are still young, in the days of no father, no mother, no brother, can they grow up safely?

But when she saw Yang Heng's firm eyes, her heart quieted down.

Although his heart was quiet, he didn't expect the situation in front of him, although this little baby's face was full of pockmarks, but this fate was saved, wasn't it.

"Baby, baby, you have to always remember your eldest brother's kindness, and don't forget your brother's goodness when you grow up, or you can call me Nian Ge'er, Nian Ge'er, Nian Ge'er, mother's flesh and blood."

Looking at this warm picture, the maid and nurse who struggled back from the line of death on the side were also full of tears. "Congratulations to the mistress for having such a kind little Langjun, and such a blessed little Langjun." As she spoke, Yingying knelt down for the old lady.

"Zaohua, you, what are you doing, you are the old man next to me, why don't you know my temper, what I don't like the most is that someone kneels, get up, get up." The old lady quickly grabbed the jujube flower.

"Master's mother, just let me kowtow to you, the slave's life was saved by the big and small Langjun, and the slave's good life was also given by the master's mother's family. It is right for a slave to kowtow to his master's mother. Otherwise, it will make the slave feel very sad. ”

"Hi. You kid, you also know that our family is not from a good background, so we are developed, and my eldest son doesn't let us treat you people as subordinates. Get up quickly. ”

Indeed, in Yang Heng's heart, the division of labor is different, at least he thinks so, although most of these servants are bought, but so what, they are all living people, so they are all given a salary, but Yang Heng did not really mention them to the same position as himself, you must know that this is in the Tang Dynasty, he will not risk the world to make a big change. Even sometimes Yang Heng is very disregarded for human life, that is, there are subordinates who do things against the interests of their family. This is Yang Heng's previous life, if there are people who have reached such a status as the Yang family, they will also be so disregarding the lives of their employees, and they are also very charitable, they will cry for a dog being killed and eaten, and they will run around for the rights of dogs, but if a dog bites him, do you see if he will beat the dog to death, and even if he eats dog meat behind his back, he will eat it more ruthlessly.

Hehe, it's a bit of a stretch.

A few days later, three people had fever symptoms at the same time, it seems that this smallpox can be fatal as long as it is strong or not, but this is not a human pox, but cowpox, you must know that cowpox has smallpox virus in it, but there are also some resistance genes, to say that these three people are dangerous, it is impossible, this fever is normal.

"Xiaoyou, look, is this normal, will it be very fatal, why do they all have a fever." Sun Daochang began to be calm. "Don't worry, Daochang Sun, this is normal, my little brother began to have a more serious fever, and it was still a real infection, and this is not for the test of pox, if they don't have a fever, then it may be a failure, and the fever is normal." "Really?" Sun Daochang left suspiciously.

Why wasn't he calm, because none of the smallpox patients he saw before could survive, so he was so nervous, and when he heard outside that someone in the Yang family had smallpox, he also rushed in, you must know that he is also one of the main objects that Li Er asked those vigilant soldiers to guard against entering, but can they stop Sun Lao Dao, you must know that he has practiced Tai Chi, and those soldiers did not look at such a bad old man would be so flexible, just limped, The soldiers who faced him were left behind by him, and he entered the Yang family.

"Boy, after Lao Tzu is gone, you have to treat your mother and relatives well, as well as your younger brothers and sisters......" "Okay, okay, grandpa, wait until you really want to die and leave your last words, you still have to experience this feeling now, you must know that you are doing an experiment, if you just think about how to leave a last word, I will find another person to test if the test is delayed." "You stinky boy, how can you talk to your father, you said that Lao Tzu is fine, and this fever is fine." Daddy seemed to be frightened, and he had a fever and began to say his last words.

"I said it's okay, it's okay, you can feel this feeling well, and then tell Sun Daochang, you two too, otherwise I won't be able to spare you." In order to reassure these three people, Yang Heng had to intimidate them, in fact, what did they need to feel good about, and Sun Simiao was observing it was true.

"Little friend, you are, oh, you have a good experience, otherwise the old Tao will not spare you." This old man quickly understood Yang Heng's thoughts.

After a few days, the trio's body temperature slowly began to fall, indicating that the experiment was basically successful.

"Little friend, should we let them contact the source of infection for testing?" Lao Dao has been with Yang Heng for a long time, and some of the terms are very slippery, although he doesn't understand what this word means, but it can't affect Sun Lao Dao's enthusiasm for learning, right, especially some nouns are more vivid than the ones he created, so he likes this statement.

"Don't worry, don't worry, who knows if this will work or not, otherwise, let's plant a cowpox on the cowboy's body and see, maybe using him to test it is the best way." Earlier, Yang Heng was not sure whether this cowboy had smallpox or not, but only found a few pox spots on his hands, so Yang Heng did not let him test first, but first let him make up for his body, although the strength of this body is the same in the face of infectious diseases, but after all, people in good health have stronger resistance, right?

"Don't worry, kid, just blow some of this powder into your nostrils and it's nothing." "I'm not worried about this, I'll clean it up when the cow is sick, I'll touch it too much, it'll be fine, you can blow it." Yes, why didn't Yang Heng ask him earlier, if he had asked earlier, he could have done the experiment earlier, but this can't be stopped, these are some rules formulated by Yang Heng, everything must follow the rules, otherwise this is also a very dangerous thing, if the person dies, it will not be good.

A few days later, Yang Heng officially determined that this cowboy had indeed been infected with the virus, and he did not have any symptoms of fever, and he was even more energetic than when he first arrived, so Yang Heng and Sun Daochang unanimously decided that the second phase of the trial was officially launched, and at this time, the father and the other two subordinates also had no uncomfortable symptoms at all, and it was suitable for the second phase of the test, that is, to expose them to the smallpox virus of people.

This second phase of the test will take a long time, Yang Heng's plan is to observe at least half a month to a month, and the outside alert time is about to expire, so naturally they can't be released from the alert now, go on, just shout to the outside world, and this matter naturally has to let Dr. Liu go out and shout.

This is also the only use he has here, since he went out of the old lady's courtyard, he has been hiding in a small room by himself, and he does not dare to come out, it seems that this person is a doctor is invalid, and I don't know why he chose this profession, maybe it is purely for the sake of being an official. In fact, this kind of thing is an outlier in Datang, there are too many types of imperial examinations at this time, so this kind of thing will happen. (To be continued......)
