Science has its own unique charm, and Zhang You is just showing the tip of the iceberg to Ye Xianggao and them. They are all the pillars of the future of the empire, and once they become interested in scientific research, they will have an immeasurable impact on the direction of the future empire.

Seeing that a few people were listening attentively and looked thoughtful, Zhang You struck while the iron was hot and asked Guo Zaoqing next to him: "By the way, sir, to what extent has the invention and creation of our Gewu Institute been selected?" What are some interesting discoveries? ”

"There are a lot, our Ming Dynasty is also full of talents, if we didn't carry out such a selection activity, there may be many talents in the people to be buried...... As it happens, one of the guys is working on a gadget that is similar to the experiment you just did. ”

"Oh?" Zhang You's eyes lit up: "What gadget?" ”

"He is a porcelain kiln, made two small porcelain cups, one of the cups has a small hole at the bottom, and then the mouth of the cup is opposite, from the small hole at the bottom of the cup to inhale, the result of the two cups are stuck together, it takes a lot of strength to separate, I once asked him what the principle is, he told me, it is said that the air we breathe is actually weighty, suck out the air between the two cups, the weight of the outside air will act on the outside of the cup, and the two cups will be firmly squeezed together."

"Okay, the ordinary place is magical, and he actually discovered the secret of air pressure." Zhang You rushed out of his mouth, thought about it and said: "In fact, this is a very common phenomenon in life, such as the principle that cupping is used, and it is rare that this person has a heart...... To put it bluntly, all great inventions actually appear like this, like hot air balloons, like hot steam engines. ”

"What is a heat engine?" Fang Congzhe's curiosity was very strong, and he asked with great interest.

Ye Xianggao and Zhang Fuzhi, including Shen Yongmao, were also very interested, and waited for Zhang You to follow up.

Zhang You didn't answer this question immediately, but first glanced at Guo Zaoqing, saw him smile and nodded, and then said: "It's hard to say if you're interested, so let Mr. Guo lead you to visit the Gewu Institute, not only the heat engine, but also the new gadgets." ”

"Okay, good, I don't dare to ask for it." Zhang Fuzhi said happily.

Shen Yongmao also said: "I have long wanted to visit the Gewu Institute, but unfortunately the place is tightly guarded, and there has been no chance. ”

"What about you, sir, aren't you going with us?" Fang Congzhe asked.

Zhang You shook his head: "I won't go, there are many things." Go ahead, remember to come over for dinner in the evening. ”

Shen Yongmao and Ye Xianggao followed Guo Zaoqing out of Zhang's Mansion with great interest, and Zhang You personally sent them to the gate, and went directly to Li Shuo's small courtyard after returning.

Hearing that he hadn't eaten breakfast yet, Li Shuo hurriedly ordered the maid to bring him all kinds of snacks and pour him a glass of steaming milk.

He was really hungry, gobbled up a few pieces, and after explaining that he would not come back to eat at noon, he went out with Li Yan.

"Is Xia'er okay? Glancing at Cining Palace, it seemed to be thinner. Getting into the carriage, Zhang You asked.

"That's it." Li Yan sat at the door of the carriage, looking at the pedestrians on the street in a daze.

The carriage is naturally the Ye's car dealership, the business in Jiangnan is in full swing, and the Jingshi side is also good, they all know that it is Zhang You's business, safe, fast, and there is no official trouble, so they are willing to choose them, especially those who do business, as soon as they arrive in the Jingshi, the first thing is to charter a carriage for the car, not to mention the convenience of travel, and face.

If you knew this was the case, why bother in the first place?

Zhang You sighed secretly and changed the topic: "Come in and sit, it's warm inside." ”

Li Yan hesitated for a moment and moved into the carriage.

The driver asked in a loud voice, "My lord, where are we going?" ”

"Kitajin Fuji."

"Holo." The driver agreed, and raised his whip and shook it in the air, "Drive!" With a sound, the carriage sped up.

Li Yan put down the car curtain, sat down close to Zhang You, and suddenly fell into Zhang You's arms, Zhang You was stunned, hurriedly hugged her tightly, and asked softly, "What's wrong, aunt?" ”

"Zicheng, am I particularly bad?"

"How can you think that?"

"For the sake of the illusory sect cause, I don't hesitate to sacrifice Xia'er's happiness and send it to the cold palace, that's it, I know that Xia'er also likes you, but I don't know ...... shame"

Her voice choked up, and she couldn't go on.

Wang Jinxia likes me?

Zhang You was a little dazed, carefully recalling the few times he got along with her, and felt that it seemed to be really like that.

He had already been vaguely aware of it, but he had never been willing to think about it - that was Zhu Yijun's woman, even if he confirmed that she liked him?

"I don't blame you, if I don't seduce you, how would you ......"

"No, it's still that my will is not strong enough, I always knew that this was wrong, but I couldn't control myself...... 'Wait for my long hair to reach my waist, can the general return?'" This gentleman is carefree, how can he expect the mountains and rivers to be bleak. The sky is broken, and the twilight snow is white-headed. Han Jian listened silently to the thunder, and the long * spear guarded the empty trench alone. Drunk and lying on the battlefield, Jun Mo smiled, and blew through the corner of the painting overnight. Late visitors from Jiangnan, red rope knotted hair. 'Do you remember this poem, when I first heard it from your mouth, my heart was touched by you, I ......"

"Auntie, do you regret it?" Zhang You suddenly interrupted Li Yan.

Li Yan's body stiffened, and she suddenly raised her head to look at Zhang You, with tears in the corners of her eyes, but she shook her head very firmly: "I don't regret it, I never regret being with you...... I just feel sorry for Xia'er, I'm not a good mother......"

"What? Aren't you Xia'er's master? How......? Zhang You was taken aback.

Li Yan reacted and said that she had leaked her mouth, hesitated, as if she had made up her mind: "I didn't want to tell you, but since I missed it, I won't hide it from you, in fact, Xia'er is my biological daughter, I was originally the holy daughter of the Yellow Heaven Sect, and I was the first choice to inherit the position of the sect leader, but I didn't want to make people worse, seventeen years ago, I met Xia'er's father, at that time, I was just out of the rivers and lakes, and my mind was simple, but his father was suave and unparalleled, so I ......"

At this point, she stopped abruptly, apparently mired in some kind of memory.

Zhang You faintly felt a little jealous, but thinking about it a long time ago, he thought about it, waited silently, and then asked, "Now, where is he?" ”

"Dead." Li Yan came back to her senses and said dryly.

"You killed it?" Zhang You couldn't help but ask.

"No, although I really wanted to kill him with my own hands, I still couldn't do it, he did it himself...... After being with me for a while, soon he got tired of me, I went crazy looking for him, but found his traces in a brothel * in the capital, I was like ashes, turned away, a few years later, I heard that he had flower willow disease, and then, came the news that he had died. ”

As she spoke, she paused and looked up at Zhang You: "Zicheng, one day, you will get tired of me, right?" ”

"No, even if you lose all your teeth one day, I still like you." Zhang You said word by word, and after that, he hugged Li Yan tightly into his arms.
