Suddenly, he reached out and pinched Cheng Yinyin's fleshy little face, then pulled it hard to both sides. Seeing that the baby's fat face instantly turned into a big cake, Li Hao's mood suddenly improved a lot: "Hahaha..."

"Li Dejian, you're going to die!" The fierce loli knocked off Li Hao's hand: "Why don't you come back from Mobei to come to see me?"

After staring at the loli with three flat and four round tablets for a while, Li Hao curled his lips and said, "I'm a little brat, I'll see what you do."

"Li De Jian!"

"Okay, okay, I surrender. Next time, I will go back from a long distance next time and see you first."

It is not scary for Loli to get angry. What is scary is Lao Cheng. I heard that the old guy will be back in less than half a month, but he must not remember it.

Li Hao raised his hand to surrender, and changed the topic: "Have your brother sent me a letter? I haven't seen you for more than a year. I don't know how he and Changsun were doing in Baekje. These unscrupulous people don't know how they wrote me a letter."

Cheng Yinyin rolled her eyes and did not take Li Hao's fault.

The girls of this era are very precocious. They basically understand everything they should understand at the age of thirteen or fourteen, not to mention that the little loli was born into a wealthy noble family.

In her opinion, Li Hao's obvious behavior of coaxing the child was just perfunctory, and she obviously came first.

That's right, it's just coming first, Lao Cheng can prove it.

But why did this bastard go to the Rencheng Palace first after returning from Mobei? Is it because Li Xueyan is relatively big?

As expected, men don’t have a good thing, they are all big pig’s hooves.

He stretched out his calf and kicked Li Hao's leg, and said angrily: "Aren't you lame? Why is it going to be so soon?"

The kick was not heavy, almost like tickling, but Li Hao still held his legs and rubbed them in a fake manner, and then said with a frown: "Emm..., if I say that the doctor told me to exercise more, do you believe it?"

I believe you, a big-headed ghost, Cheng Yinyin snorted and said, "Okay, don't pretend. Even if the past is over, if you leave Chang'an again in the future, you must come to see me when you come back, otherwise I will ignore you again."

Li Hao immediately nodded with relief: "Well, it will definitely be next time."

Anyway, he doesn't plan to leave Chang'an in a short period of time, and he is not afraid of breaking his trust.

"You are in Mobei..., are you seriously injured? I heard that you were in a coma for five or six days, almost... almost..." After losing your temper, the little loli finally returned to normal and stared at Li Hao and asked softly.

"It's all spreading rumors, don't believe it." Li Hao smiled bitterly and shook his head. Good things don't go out, bad things spread thousands of miles. It seems that he is in Mobei, Chang'an, probably because he doesn't know how many versions of his affairs have been circulated.

Seeing him say this, Cheng Yinyin sighed: "Please pay attention in the future. Three thousand people dare to fight Jie Li with 100,000 people. I really don't know what you were thinking at that time. I'm not afraid of something happening. You know, there are many people in this world who care about you. If something happens to you, I will eventually be sad...they."

He looked at the little loli in surprise. Li Hao really didn't believe that such words would be said from a thirteen or four-year-old loli.

At this age, I was still carefree at that time, and I considered eating, drinking and having fun.

"Who can tell the things on the battlefield clearly? Often times it's not whether you think about it or not, but the enemy is right in front of you, either fighting to the death or becoming a deserter. I don't think you like me as a deserter, right?"

"Well said it! I, a man from the Tang Dynasty, should do this." The sudden voice interrupted Cheng Yinyin's original words, 'I would rather you be a deserter'.

The two turned around in surprise and saw the visitor clearly and quickly saluted: "My minister Li Dejian (the little girl Cheng Yinyin), join Your Majesty, Empress."

His Majesty Li Er, surrounded by more than a dozen guards, waved his hand lightly: "Forgive me, I will leave the palace in a very small way this time, and I don't want people to know."

Empress Changsun smiled and walked up to hold Cheng Yinyin: "What a handsome little girl, I haven't seen her for two or three years, and she has become a big girl."

"Empress..." Cheng Yinyin was pulled by the queen, and her chubby little face showed an embarrassed smile.

"Yes." Empress Changsun nodded, and her deep eyes swept across Li Hao and Cheng Yinyin, with the meaning unknown.

"Empress, I met Yinyin here by chance..." Li Hao was afraid that she would misunderstand, so he quickly explained, but he didn't expect that he would get darker and darker, and Empress Changsun's smile became more and more ambiguous.

I was so anxious to explain what it means. Could it be that I am not worthy of you? Cheng Yinyin was calm on the surface, and secretly stretched out her slender little hand and turned ninety degrees around Li Hao's waist through her clothes.

"Hiss..." Li Hao's expression immediately became more exciting.

This girl is really cruel to attack. Her waist must be pinched to the point of being blue.

Fortunately, his rationality is still there and he did not foolishly ask "What are you doing for pinching me?" Otherwise, the consequences will be unpredictable.

"Come on, accompany me for a walk." Li Er, who had something to do, didn't care about these children's love. He just looked at Cheng Yinyin with thoughtfulness, called Li Hao over, and said as he walked: "Did you send the fruits in the palace?"

The pain on Li Hao's waist had not yet recovered. He grinned and rubbed his teeth. After hearing this, he reacted for a while and said, "Ah, yes, it was my gift. If your Majesty feels it is not enough, I will send you another batch in a few days."

Li Er paused and looked at Li Hao without any comment: "If I read it correctly, those fruits should be newly picked."

"Yes, I picked it last night. I was afraid that it would not be fresh after being left for a long time, so I sent someone to deliver it to you early in the morning." Li Hao's tone was relaxed, as simple as saying what he ate last night.

Li Er was so angry that his teeth were itchy after hearing this. If he could put aside his identity as an emperor, he really wanted to say, "You pretend to be like this."

His face darkened and he raised his foot to kick Li Hao in the butt: "Li Dejian, don't give me a sloppy eye, tell me honestly what those fruits are."

"Oh..." Li Hao was kicked and staggered. He replied honestly: "These are grafted varieties grown from the Technical College. The glass house outside is fastened to control the temperature, and then artificial pollination can produce fruits."

Well, it’s concise and concise, Li Er can understand every word, but what are they connected?

Except for knowing that it was the result of the Technical College, Li Er could not understand the rest. The intellectual crush made the imperialist leader feel like a country bumpkin.

‘Bang’, another kick.

"Speak human words!"

Li Hao was in tears.

In less than half a quarter of an hour, there were two huge shoe prints of forty-five sizes added to some indescribable parts behind him. I don’t know when Li Er got this habit.

He returned to the great Emperor with a bitter face: "Your Majesty, why don't you go to the Technical College to see it. I just want to explain this matter, but I can't explain it clearly for a while."

Driven by curiosity, Li Er hesitated at any time and waved his hand to walk outside the Furong Garden.

Cheng Yinyin heard that she was going to the Technical College and didn't care about her own industry anymore. She was beside Empress Changsun and followed her away from Furong Garden and got on the carriage.

The book was brief, and the group took some time to come to the heavily guarded technical college outside the city. Yuan Tiangang, who had received the news earlier, was already waiting outside. After seeing Li Er, he changed into a carriage inside the college and headed straight to the Biological Engineering Academy.

Li Er, who came to the college for the first time, curiously lifted the curtain to look around. Although he did not lack external information in the palace and had some understanding of the internal affairs of the technical college, it was better to see the truth with his own eyes.

Yuan Tiangang seemed to have met Li Er before, and he was not nervous when sitting in a carriage. Every time he passed by a branch, he would introduce his functions and projects he was studying. He was confused and began to doubt his life at one point.

A mirror that can reveal the slightest bit of a person's body; a spinning wheel that can compare to the workload of twenty people; a telescope that can see the moon clearly; a papermaking with straw and reeds... These are all within a barely acceptable range.

But what the hell is studying smallpox in the plague? Can that be studied by humans?

"What's the thing? Can you study the smallpox virus now? Do you know how many people will die if it is not controlled properly?"

Li Hao's face was scared. Old Yuan hadn't told him that the medical school would study this thing, otherwise he wouldn't have brought Li Er to the Technical School if he was beaten to death.

"The prince doesn't have to worry so much. The smallpox project team is not in the academy." Yuan Tiangang's tone was fanatical: "And they have already developed some preliminary research. I believe that it won't take long before smallpox will no longer bother my natural disasters."

Li Hao blinked, "You are trying to die. Who gave you the courage to study smallpox without any protection? Isn't the research projects I have given you? Isn't it good to study hybrid rice? Why don't you go to heaven when you study smallpox?

Unlike Li Hao, Li Er expressed a strong interest in the smallpox project team that Yuan Tiangang said: "Master Yuan's words are serious? Can smallpox be cured?"

"I dare not say that I cure it, but at least it can be prevented." Yuan Tiangang said excitedly: "According to Brother Sun's research, as long as a person has been infected with smallpox once, he will not be infected again, so..."

"So you use humans as an experiment, scrape off the patient's dried scabs from above and blow them into the nostrils of normal people who are not infected, causing mild infections to produce antibodies, right?"

Li Hao really couldn't stand it and Yuan Tiangang was in a silence, so he couldn't help but reveal his mystery in advance.

In fact, some people will develop this method in a few hundred years and will have a great effect on preventing and treating smallpox.

But it is a bit inhumane, and it is not a cure for symptoms. After all, smallpox is common, and people who have contracted smallpox and are not often dying.

Unexpectedly, Yuan Tiangang shook his head: "We have never thought about this method before. I'll remind them afterwards."

Li Haoqi said: "It's not this method, so how did you do it?"

"Brother Sun's method is to cut a cut into a human body and then apply acne from patients with smallpox."

Li Hao said mutely: "Growing...snit acne? You have all developed this? Then how did you cultivate acne seeds? Could it be a living person?"

"Uh..." Yuan Tiangang lowered his head with a slight silence. It was obvious that Li Hao had guessed it right.

This is really not a human life. Li Hao no longer knows how to evaluate the doctors of this era.

But then again, this seems to be in line with the purpose of doctors in this era. If you cut your hands with pain and your feet with pain, you will have no disease that cannot be cured as long as you dare to take action.

Unlike Li Hao who cares about life, Li Er cared about the results of the experiment. Seeing that the two stopped arguing, he frowned and asked, "Master Yuan, what you said can really prevent smallpox?"

Yuan Tiangang nodded with certainty: "It's true that everyone in the smallpox research group used this method to prevent it. Except for having mild fever at the beginning, no matter how they contacted smallpox patients, they were never infected again."

"Okay, okay!" Li Er was overjoyed when he heard this, and smiled: "Master Yuan has solved the big problem for my Tang Dynasty. If my Tang Dynasty has no worries about small flowers in the future, the Taoist Master can become a saint."

"Your Majesty is a mistake. All of this is the credit of Sun Simiao and Brother Sun. The entire research team is conducting research under his leadership. The fork road is just doing its duty and allocating some money to them." Although Yuan Tiangang was kind-hearted, the smile on his face could not be concealed.

This is smallpox. There are no less than tens of thousands of people who die from smallpox every year in the Tang Dynasty. If it can be completely cured, it will definitely establish an unshakable position in the hearts of the people of the Tang Dynasty.

After hearing this, Li Hao felt his heart was about to break. No wonder the technical college spent money in the past six months. It turned out that these lunatics had opened so many projects behind their backs. It would be so strange if they could save money.

And that old Taoist named Sun Simiao is the same. You said you are not good at studying, and you have to study...

"Wait, who did you just talk about? Sun Simiao?" Li Hao finally reacted and grabbed Yuan Tiangang and asked anxiously.

"Yes, what's wrong?" Old Dao Yuan asked in surprise.

"No, nothing." Li Hao shook his head with a wry smile.

I have only been away from Chang'an for half a year. This has changed so much. Even Sun Simiao has run to me.

It seems that it is necessary for me to stay in the Technical College for a few more days to see what these guys have done with me on their backs, and how many celebrities have unknowingly run to their college to hide.

In silence, the special carriage inside the college stopped in front of a huge glass house.

In the noon sunlight, the glass house reflects a dazzling light, and you can see the green vegetation inside through the glass.

Before Li Er got off the car, he was already shocked by everything in front of him and widened his eyes.

Queen Changsun in the car behind closed her mouth in surprise, looked at the huge building in front of her, and heard Cheng Yinyin murmuring herself: "Oh my God, how did this be made?"
