Da Qin: Give Ancestral Dragon the elixir of death at the beginning!

He Chao heard Ying Zheng's praise,

The expression on his face did not fluctuate, and he waved his hand directly:

"Father-in-law, I don't need any reward,

These are just small things to me! "

"Besides, when I went out of the city, the people of Nanzheng County had already come to see me off.

With that alone, I'm already satisfied. "

Seeing He Chao so indifferent to fame and fortune,

The look of appreciation on Ying Zheng's face was even stronger, and he nodded again:

"Haha, the virtuous son-in-law is really indifferent to fame and fortune!"

"You saved the name of the people of Nanzheng this time,

Their kindness to them will surely not be forgotten! "

He Chao nodded noncommittally, remembering the scene where the people of the city sent him out of the city gate,

A relieved smile appeared on his face.

Fusu also followed to the imperial study, and after hearing Yingzheng's praise for He Chao,

couldn't help but look at He Chao with admiration and awe.

His master sealed a city for each person,

Saving hundreds of thousands of people from smallpox is amazing!

And he is a disciple of He Chao, and he is full of honor!

Thinking that He Chao would give him so many awesome things in the future,

Fusu was in a mood again.

After praising He Chao for a while,

Ying Zheng remembered what He Chao said in the letter again, and couldn't help asking:

"By the way, son-in-law, why does cowpox prevent smallpox?"

He Chao was speechless for a while, he had already said it in the court before.

Now the old man came to ask him again, probably because he didn't take it to heart.

However, since Ying Zheng took the initiative to ask, He Chao could only explain again:

"Because vaccinia is the result of the immune system in the cow's body fighting the smallpox virus, after the cow's immune resistance,"

"Cowpox not only contains the smallpox virus, but also has antibodies against the smallpox virus."

"So, just inoculate this cowpox into healthy people,

People will also have a corresponding resistance to smallpox, and they will never get smallpox again! "

After hearing He Chao's explanation, Ying Zheng was still confused, and couldn't help asking:

"Son-in-law, what is this antibody?"

"Antibodies are proteins of a hell virus in our body.

To put it simply, antibodies are like an extra shield on our body.

It can help us with the invasion of bacteria and viruses in hell. "

Ying Zheng still didn't understand it when he heard it,

But he didn't plan to ask any more, and said with a sneering smile:

"It turns out that there is such a deep knowledge here, you are really knowledgeable!"

He Chao nodded, then nodded with a smile and said:

"Haha, father-in-law, this is the power of science I told you!"

"As long as we continue to study science, we can also explore the deeper mysteries of nature!"

Ying Zheng nodded thoughtfully,

With a look of longing on his face, he clapped his palms and praised loudly:

"Well, it seems that I made the right decision to establish a scientific research institute and vigorously promote science throughout the country!"

"As long as science is thoroughly promoted, I believe that everyone in Daqin will be like a dragon!"

He Chao nodded, Ying Zheng could have this realization, which also made him very happy.

Ying Zheng suddenly thought of something again, looked back at He Chao and asked:

"By the way, son-in-law, how is the preparation of the Academy of Science?"

He Chao nodded and replied:

"It's almost ready, and we can start construction soon."

At this time, the eunuch of the imperial study went to Yingzheng's side and whispered,

Ying Zheng nodded suddenly in understanding:

"Virtuous son-in-law, you have made such a great contribution this time,

I have set up a banquet in the palace to catch the wind and wash the dust for you! "

"Thank you, father-in-law!"

He Chao was not polite, he rushed back all the way, and his stomach was indeed hungry.

Subsequently, Ying Zheng prepared a sumptuous banquet,

took He Chao and Yingchman, as well as a few important ministers, to eat together.

At the wine table, several people were staggered, eating and drinking very happily.

Ying Zheng was very happy, drank a glass of wine, looked at Meng Tian and asked:

"Meng Aiqing, now that spring has begun, how are the preparations for attacking the Huns?"

Hearing Ying Zheng ask about the attack on the Xiongnu, Meng Tian replied excitedly:

"Back to Your Majesty, we have been ready for a long time,

If it hadn't been for the sudden outbreak of smallpox, we would have set off a long time ago! "

Ying Zheng nodded, and then ordered in a deep voice:

"Haha, okay, I'm ready to rest assured!"

"Meng Aiqing: This time the soldiers are so well prepared,

The snow is melting again, so be sure to take down the head of Maudun! "

Meng Tian heard the blood surge, and hurriedly clenched his fists to receive the order: "Yes, Your Majesty!" "

He Chao on the side didn't take it to heart when he heard it, he gave Meng Tian so many good things,

If you can't destroy the Huns, then it's strange.

"Ding! Congratulations to the host for a new mission! "

"The content of this mission: The host and Meng Tian set out together, and then cut off the head of the Khan of Maotun with his own hands!"

"Reward: 1,000 steam engines and improved breeds of chickens, ducks, cows, sheep, pigs and other livestock!"

When He Chao was eating happily,

The long-lost prompt sound of the system sounded in He Chao's mind again.

The system actually asked him to fight the Huns too?

Reward him with the principle of the steam engine after the event?

He Chao was stunned for a moment, and immediately became excited.

But what the hell is this improved breed of chicken, duck, cow and sheep?

Is the system going to let itself go on a farm?

However, based on the principle of the steam engine, He Chao planned to take over this task.

After all, with his force, it would not be a problem to cut off Mao Dun Shan Yu's head.

Thinking of this, He Chao put down his chopsticks and said to Yingzheng:

"Father-in-law, let me go with General Meng this time."

Ying Zheng was stunned for a moment, and then laughed:

"Haha, yes, the virtuous son-in-law is very resourceful,

If you go out with Meng Aiqing this time, the people of Maudun will definitely be captured! "

Meng Tian was also very happy to hear it,

If He Chao goes with him this time, it will add a big boost to him!

After the banquet was dispersed, He Chao took Yingciman back to the mansion.

......

Charmaine Yingciman felt very resentful of He Chao's practice of just returning to the mansion and about to go on an expedition.

He Chao had no choice but to increase the intensity of appeasement at night to make her happy.

After a few more days, after everything was ready before the army set out,

He Chao was fully armed and Meng Tian led the army towards the Xiongnu base camp!

Ying Zheng's side has been paying attention to the movements of the army.

A week later, Ying Zheng saw that there was no battle report coming back from the front, so he asked Li Si:

"Prime Minister, the army has been on its way for seven days,

It stands to reason that it should have entered the hinterland of the Xiongnu a long time ago, what is the situation now? "

Li Si was a little embarrassed, there was indeed no battle report back from the front, so he could only reply with a bitter face:

"Your Majesty forgives the sin, there is no battle report from the front, and Weichen has not learned about the battle situation ahead."

When Ying Zheng heard this, he could only sigh: "Hey, I hope everything goes well..."

......

Deep in the north of the desert, the hinterland of the Xiongnu.

At this time, He Chao and Meng Tian led the army to kill them mightily.

A small tribe of the Huns has launched a sweep!
