But Shen Kuo must not be slow when he comes, it is very happy to have friends from afar, not to mention that this friend can help a lot. With Shen Kuo's action, Wang Qi's river embankment project is at least double the labor.

"Liang Huai lifted Changping to make Shen Kuo see His Royal Highness King Liang...... "I saw Shen Kuo again after two years, hey, it hasn't changed much, that's good, it seems that the northwest wind of Yanshan is not difficult for him, a person who has tasted the wind and snow of the Northwest Plateau."

"Don't don't, Your Highness will be exempted, let's use the main position. I'm the envoy, you're the envoy, it's just two pieces of, and there's no one who stinks. ”

Shen Kuo's meeting ceremony was a bit grand, Hong Tao didn't want him to feel that he had changed anything after he became king, so it would be difficult to communicate. His friendship with him is on academic issues, and there is no point in engaging in these, and he will not enter his inner circle.

"......" Shen Kuo was really obedient, shrugged his nose and chased after him.

"Hey, Brother Shen, you've also learned badly, do you really treat me as?" Hong Tao knew what Shen Kuo was smelling, and his body was full of hydrogen peroxide smell, which was indeed a bit like rotten eggs.

"My lord, this is ......" Shen Kuo saw that Wang Shu was still as casual as before, so he was no longer restrained, and came up to smell it carefully.

"Go, go, stay away, two big men are so close so that the next person can see what kind of body he is. This is the smell of disinfectant water, and I'm helping Eighteen with medicine for acne rashes. That thing is contagious, so many women and children in the house have to guard against it. These days, I can't eat well, and my nose is full of this smell. ”

finally came to someone who could understand himself, and Hong Tao was full of grievances and wanted to confide. It's strange to say, the eldest princess can also understand herself, but there is no point in talking to her, she is not understanding but obedient. On Mondays and Sundays, they are the same, willing to listen but not understood. Only Shen Kuo can understand and is willing to listen.

"Pox! …… This—Can this disease be cured!? This time, Shen Kuo didn't listen, but stared at the balls of his eyes, his hands were like two big pliers, it seemed that as long as Hong Tao dared to nod, he would dare to pounce.

"You sit down first, and then we'll talk about the illness...... Could it be that someone in Brother Shen's family has caused pox? This expression was definitely not curiosity, Hong Tao quickly raised his legs and made a defensive gesture.

“…… It's a long story, both of my nephews died of pox, poor thing...... If you have medicine, you can, you can, you can compare to the Buddha, and the merit is immeasurable! Sure enough, no one in Shen Kuo's family was affected by smallpox, but the disaster in his sister's family was quite serious, and two of them died, so it was inevitable that they were a little excited.

"The Buddha didn't know how to treat acne, but he found a way to avoid getting sick...... Come on, come on, go to the back garden with me to see, hearing is false, seeing is believing. ”

Hong Tao felt that Shen Kuo's understanding was a bit wrong, and he couldn't cure smallpox by himself, but could only prevent it. It's a bit troublesome to talk about, so it's better to go to the scene to observe and explain.

When the two of them entered Wang Shibai's small courtyard again after changing clothes and disinfection, there were already eight children who had been vaccinated against smallpox virus, and almost all of them had pear blossoms with rain.

"These children are ......"

After listening to Hong Tao's introduction to the process and purpose of this experiment, Shen Kuo had no doubts about the technical details, he also knew medical skills, and he could roughly understand the principle.

But I can't bear to deliberately infect my child with smallpox, what if this method doesn't work and die? Even if you are lucky enough to survive, you may be blind and deaf, and at least you have to make a pockmarked face.

"I bought it from the city...... Brother Shen doesn't have to look at each other with such eyes, this is also a helpless way. Ordinary people who would send their children here for me to test, if they don't go through the test, how can they prove the efficacy of cowpox, let alone popularize it. ”

As soon as he said that the child was bought, Shen Kuo's face immediately changed, and there were some other meanings in his eyes besides surprise. Hong Tao didn't want to lose the only ancient confidant, so he had to explain patiently no matter how unhappy he was.

"If the adult's cowpox doesn't work, wouldn't it be in vain to bury ten lives, which is too, too ......" Shen Kuo was very face-saving, and did not immediately stand on the moral high ground to accuse, but he did not pretend not to see it, and planned to ask for an explanation for these children.

"It's cruel, isn't it? If I were an ordinary person, it would be cruel indeed. But I'm not an ordinary person, and neither is Brother Shen. Since we are more capable than ordinary people, we cannot hold ourselves to the moral standards of ordinary people. Ten children who die now will save ten thousand, a million in the future. Let's not mention the things that benefit the world, and I will make a lot of money just by calculating this account. Let's go, the result will be at least ten years later, presumably Brother Shen is not here for pox, and the water is not weak at all! ”

It's time to see everything, and the test is basically done, and the rest can only wait. Hong Tao didn't want to stay in this courtyard for long, the smell was too bad, and the topic was too heavy.

"Have you ever thought about it, if the news leaks, how will the world judge after knowing about it?" After leaving the small courtyard, Shen Kuo couldn't get rid of this matter for a long time, and it took a while to calm down before his soul returned to his senses.

"You'll definitely scold me, you'll hate me, you'll understand me, who knows. Some things can't be done in a variety of ways, and if you want to succeed, you have to take risks. ”

The question asked by Shen Kuo was very heart-wrenching and difficult to answer, but it was nothing here in Hong Tao. He was unwilling and unaccustomed to thinking emotionally, and although it seemed warm, there was no reason behind it.

On the contrary, rational thinking seems cold and ruthless, but it is more affectionate in its bones. Which one is right, Hong Tao doesn't know, so let's do it according to his own ideas for the time being.

Why can Shen Kuo talk to Hong Tao? The reason is simple, he is also a weirdo, less emotional and more rational. It is said that he had a strong wife, who was so strong that she beat him up when he had nothing to do. In this case, he can still calm down and study something he is interested in, such as airplanes!

Since Da Hongtao handed over the plane drawings to him, making people fly has become more important than building river embankments and walled forts, and even if he is very busy with work, he still has to spare most of his time to study this big toy. Therefore, during his time in Yanshan, he did not devote himself to the imperial court, but did private work in the fake public economy.

As the saying goes, as long as the kung fu deep iron pestle is sharpened into a needle, the ancients also said that 99 percent of success depends on hard work, and one percent depends on luck. But luck doesn't come often, and hard work is there every day.

Shen Kuo is a lucky person who has both hard work and luck, and to put it mildly, he is already the first person in the world to use a man-made aircraft to fly into the sky. Although it was only an unpowered glider, it was a remarkable achievement to be able to fly in the 12th century.

"Where are you an airplane, at most it's called a flying wing, it's far from the plane." Such a great achievement is not considered bullshit in Hong Tao's mouth, and he pouted and couldn't look down on a hundred after just looking at the drawings.

"But, according to the instructions of the adults, it can really fly!" Shen Kuo is really unwilling, he has worked hard for more than a year, and he almost fell to his death several times, in exchange for such an evaluation?

If others dare to say this, they must go up and draw the round, and if they can't beat it, they have to break up. But I can't be in a hurry when I change to a colt, and there are not many Mr. Screams, so how dare I make a mistake.

"Definitely flying...... You can fly even a kite, but you're a big kite, you can't take off on your own, and you can't decide for yourself how far and how long you can fly, it's all controlled by the hot air flow and wind direction. This should be called floating, not flying. Flying is up to people, you can fly if you want, you can fly wherever you want, do you say no? ”

Hong Tao is not ignorant, nor does he really look down on this glider, he is deliberately so derogatory. Why, because he was digging a pit for Shen Kuo, the pit was quite big, and he wouldn't jump down if he didn't stun Shen Kuo.

"This—How can this be done?" The green tendons on Shen Kuo's neck jumped up, he really didn't have a backache when he sat and talked, and he could fly whenever he wanted, God is your family!

"How can you not do it? You see, this flying wing...... Let's call it an airplane for the time being, why does it have to fly from a high place to the wind? "It's reliable, as long as you are in a hurry, you will lose some of your vigilance, Hong Tao walked to the edge of the pit again, and led Shen Kuo with questions.

"Adults don't say that there is wind in the sky, the wind is air, as long as the speed is fast, the wings of this shape can hold the air without falling. That's true, if you put the wings upside down, it won't be able to fly......"

As soon as he heard this question, Shen Kuo's green tendons immediately subsided, no rut, his skills are not as good as others. Although I still can't figure out the truth of what the colt said, I have verified them one by one, and they are all true.

"Shhh...... Yes, speed is key! If your plane can run faster than a horse on flat ground, does that mean it will rush down at a high altitude? ”

Hong Tao slapped his thigh, his strength was a little stronger, and he grinned in pain. Shen Kuo is really a genius, he actually figured out the general principle of aerodynamics, and only relied on his own manual of a few pages. So this pit must be made for him to jump into, and no one is qualified.

“…… Wonderful! If the wind does not move and the plane moves, it is the same as the wind moves and the plane does not move...... No, how can an airplane run so fast on the ground, do you have a way! ”

Shen Kuo was surrounded by this theory, sat on the chair and almost didn't pull his beard off, and slapped his thigh violently, figuring it out! But immediately frowned again, it was useless to just think about it, how could this thing be tested? I can't test it, it's not the same as dreaming, it's useless.

"Hey, hey, hey...... Naturally, there are ...... However, Brother Shen can't be fooled like Youzhou anymore, Wang Qi has to do his best to help build the river embankment, can you agree? ”

Hey, at this time, Hong Tao felt that Shen Kuo had followed him to the edge of the pit, and he only needed to make a gorgeous turn, and then gently pushed him behind his back, and he fell in.

"The adults laughed, how can it be in Youzhou...... Please rest assured, as long as you can make the plane fly on its own, you will go all out to help the Seventh Prince build the river embankment! ”

What Shen Kuo should have done at this time was not to pat his chest and ensure that he did a good job, he should have screamed. This big pit is so deep, I'm afraid I won't be able to climb out of it for half my life.
