The principle of this device, which Cui Geng made in three days, is very simple.

It is to light the firewood underneath, and use the principle of gas expansion and cold compression by heat to generate power and drive the fan to run. The wind blown by the fan passed through a large piece of "Tibetan ice" in front of it and turned into a cool breeze, which was equivalent to the air conditioning fan of later generations.

The whole energy conversion process was, of course, very uneconomical, and this kind of fan was a flash in the pan in 19th-century Germany and was quickly phased out.

Of course, the technical level of the Tang Dynasty is far inferior to that of Germany in the nineteenth century, but at the same time, Cui Geng does not need to achieve such good results.

Even if he had to build this device to be extremely large, even if this device could not last long, as long as he really did not rely on manpower to send out cool breezes, it would be like a miracle in this era.

Yang Chongren exclaimed: "King Fuyang made this ...... Uh, the cool fan, it's really amazing, I'm afraid that only the wooden ox and flowing horse of ancient Zhuge Liang can be compared with it. ”

Cui Gengdao: "Whether it can be compared with Zhuge Kongming, don't care for the time being." But this official is worth a treasure with this thing, can Old Man Yang recognize it? ”

"Yes, of course I do."

"That's not right." Zheng Yun was still a little unconvinced, and said: "This thing made by Cui Xiang is indeed extraordinary, but it is stupid and coarse, how can it be compared to the top ten treasures?" Take a look at Ben Gongzi's self-warming cup, and then look at the warm jade saddle of King Zi, is that a good thing? ”

"You're stupid!" Song Genhai said disdainfully: "No matter how good your self-warming cup is, it's just like that." My family's cool fans can be made as much as you want. Even if one piece can't match your self-warming cup, what about hundreds of pieces? ”

"Uh......" Zheng Yun was speechless for a while.

Xue Shu, who had been watching the excitement of Zizhou, suddenly interjected: "Zheng Gongzi can't be too nitpicky, in fact, Cui Shangshu wants to make this thing more exquisite, and it is not impossible, for example, all the wood used is changed to sandalwood, and then decorated with pearls and jade." In terms of appearance, it may not be worse than a self-warming cup. ”

Who the fuck are you?

Zheng Yun glared at Xue Shu fiercely, and said angrily: "Then now the King of Linzi, the King of Fuyang, and the son of Ben have all taken out a treasure, and they are evenly matched." Then according to Xue Thorn's opinion, who should Yang Xiaoniang fall to? ”

"Who said they were evenly matched?"

At this moment, Wang Yuanbao, who had not been looked at seriously, suddenly spoke, and he said with a smile: "Don't hide it, there is a second treasure below?" ”

"What treasure?"

"But it's the Luminous Staff!"

As soon as the words fell, Zhou Xing walked in with a jade staff, the color was vermilion, and there was a loud sound when he knocked it with his hand, and what was particularly eye-catching was that there was a green orb on the head of the staff.

It's daytime now, and the light is very strong, but I don't know if this pearl has the effect of "night light".

Zheng Yun couldn't believe his eyes, and said, "This is really the Night Bright Staff?" ”

"It's like a fake."

"The Night-Bright Staff of Guo Xiu, the Hermit of Zhongnan?"

"It should be said that this treasure originally belonged to him."

"Then why is it in your hands now?"

"It's a long story......

Wang Yuanbao's night-bright staff, of course, was given by Yang Susu. In fact, this is a hole card left by Yang Chongren for himself, and Yang Susu chose whoever was the husband, so he gave him this staff.

Of course, Wang Yuanbao didn't need to tell Zheng Yun the truth.

In his narration, last night, Li Yizu, the star of wealth, appeared again and gave him this treasure.

After Zheng Yun heard this, his nose was so hung that he was crooked, and said angrily: "Nonsense! You are not Li Yizu's own son, why is the wealth and wealth star so good to you? It's just a dream once, and it's a special dream twice:"

Wang Yuanbao smiled slightly and said, "I don't know what the reason is." Otherwise, Zheng Jian is quite a researcher on ghosts and gods, and you can ask him to explain and explain? ”

Zheng Pusi explained a fart, and said with a pale face: "Master Yang, it seems that the dog and Ling Yuan are fated to have a part." The green mountains do not change, the green water flows for a long time, we will have a period later! ”

Yang Chongren wasn't really afraid of him, and squeezed out two words between his teeth, saying, "Don't send it!" ”

……

……

Next, Yang Chongren announced that it was better to choose a day than to hit the day, and he would hold a wedding for Wang Yuanbao and Yang Susu today.

After all, Li Longji and Yang Chongren did not tear their faces, and participated with a smile. Cui Geng and He Lou Aoqing, as Wang Yuanbao's brother-in-law and sister-in-law, of course, have to participate. What is a little strange is that Zizhou Thorn Shi Xue Shu did not leave and participated in this wedding.

After a grand wedding, everyone went back to their temporary shelter to rest.

Inside Li Longji's room.

Wang Ju bowed slightly, and said: "I didn't plan well, I missed the prince's major event, and I ask the prince to forgive me." ”

"Mr. Wang, please get up." Li Longji shook his hand and said, "If Cui Geng is so easy to deal with, he will not be the world-famous Cui Erlang." You are not to blame for this non-war crime. ”

Wang Ju stood up and said, "Thank you for your understanding." Belch...... Regarding the future, what are the prince's plans? ”

Li Longji muttered: "This king hasn't thought it through yet. We want to marry Yang Chongren this time, firstly, we take a fancy to his nearly 10,000 parts, and secondly, we take a fancy to his tens of millions of family wealth. Those parts are gone, but we are recruiting troops in Luzhou, and the cost is very large, and if there is no large amount of money in the account, we can't support it. ”

"Have you forgotten the surprise about the part? It has been arranged below, and the troops and horses on Lu Mountain can be pulled out tomorrow. What about money...... There's actually another way to do it. ”

"Huh? What's the idea? ”

"Have you heard that Yang Chongren has a younger brother named Yang Chongyi?"

"I've heard of it, what's wrong with him?"

Yang Chongyi lives in Chang'an City, and is responsible for the Yang family's glass trading in Chang'an, and his family wealth may not be less than Yang Chongren's. It's just that we're like this, like this and that...... Isn't Yang Chongyi's tens of millions of family fortunes yours? ”

……

……

At the same time, Cui Geng's room.

Xue Shu, the assassin of Zizhou, was also bowing to Cui Geng and said, "See Cui Shangshu for the lower officials." ”

"Xue Tingshi, please get up and sit!"

"Xie Cui Shangshu."

Xue Shu sat down opposite Cui Geng, and went straight to the point: "Cui Shangshu came to Zizhou this time for Zheng Pusi, right?" ”

"Oh? Could it be that Xue Tingshi has evidence of his greed? ”

Xue Shu shook his head and said: "The flood in Zizhou is slight, and Zheng Pusi can't be greedy even if he is greedy. Xia Guan wanted to report the case of his clever seizure of Shi Wenxiu. ”

"Shi Wenxiu? What the hell is going on? ”

"Cui Shangshu still remembers the self-warming cup that Zheng Pusi took out today? This cup is Shi Wenxiu's ancestral heirloom......"

Then, Xue Shu slowly told the details of the self-warming cup case.

Shi Wenxiu is 35 years old today, and there are dozens of businesses in Zizhou City, and he is considered one of the wealthy families in the local area.

Not only that, he is also willing to give, cherish the old and the poor, respect scholars, and is known as "Shida Benevolent".

Just last winter, a scholar froze in front of his door and was rescued into the house by Shi Wenxiu's house slaves.

After Shi Wenxiu woke up the man, he asked, this person's name was Jing Bai.

Jing Bai Hanzhuang studied hard for 20 years, but he didn't achieve any fame, on the contrary, because he was not good at management, he kicked and beat all the property handed down by his ancestors. Now this thorn white is not much stronger than a beggar.

Shi Wenxiu was kind-hearted, so he said, how can you also be a scholar, just be a teacher here and enlighten the children of the clan.

Of course, Jing Bai is very grateful.

Later, after a period of getting along, Shi Wenxiu found out. This Jing Bai didn't achieve fame, but he was unlucky, and he was really talented. Therefore, he was promoted to the second housekeeper of the family.

It is said that Shi Wenxiu has both life-saving grace and acquaintance with Jing Bai, and Jing Bai should repay him. However, Jing Bai chose to take revenge.

In the position of the second housekeeper, Jing Bai learned a secret: Shi Wenxiu has the world's most treasure, self-warming cup.

After Zheng Pusi came to Zizhou, Jing Bai felt that the opportunity had come and told Zheng Pusi the secret.

So, Zheng Pusi personally came to Shi Wenxiu's house and asked for 200 yuan to "buy" his self-warming cup. Shi Wenxiu refused to sell the cup, but also did not dare to offend Zheng Pusi, so he had an idea and sent a fake.

This fake is the same as a self-warming cup in appearance, but it does not have the ability to "self-heat". The rumors of the world's treasures are quite different from the real situation, and it stands to reason that they should be able to fool the past.

However, at this time, Jing Bai stood up and testified against Shi Wenxiu's fake.

Zheng Pusi was caught this time, not only did he take away the self-warming cup for a penny, but also accused Shi Wenxiu of "shoddy and defrauding people of money" and locked him up.

Shi Wenxiu's wife had no choice, so she sent the deed and title deed of the family property, and Zheng Pusi agreed to release her.

However, Shi Wenxiu suffered a lot in prison, and a few days after returning home, he died.

Shi Wenxiu's wife couldn't swallow this breath, so she begged Xue Shu to make decisions for Shi Wenxiu.

But Xue Shu was Zheng Pusi's opponent, so he had to take advantage of today's opportunity to tell Cui Geng about Zheng Pusi.

After listening to this, Cui Geng said thoughtfully: "Then Zheng Pusi forced you to come to see the official today, is it really a bit of a self-digging grave?" ”

"Uh...... If Cui Shangshu is willing to eliminate harm for the people, the same can be said. ”

"That official is strange. Zheng Pusi is not a fool, isn't he afraid of your lawsuit against him? ”

"Maybe it's because the subordinate has always been deferential to him, which made him relax his vigilance."

"Respectfully?" Cui Geng raised his eyebrows, looked into Xue Shu's eyes, and said, "Then what is the reason that makes you less submissive?" Don't tell me that your actions today are just asking for the lives of the people. ”
