Cai Boyu's Horse Mansion can be regarded as a place that does not lose to the palace, Sancai looked at the corridor here, and kept glaring at Cai Boyu, but every time he came into contact with Zhao Miaoyuan's gaze, he immediately became kind, and he did not treat Cai Boyu harshly at all, only the word respect......

This made Cai Boyu very dissatisfied, but he could only lead Zhao Zhen to the backyard with a wry smile, eating the "food" made by Zhao Miaoyuan while walking, as the saying goes, you don't get tired of eating, but if Zhao Miaoyuan's craftsmanship is outstanding, Cai Boyu will not sneak out to "forage".

He knew that Zhao Miaoyuan was just a hobby, not concentrating on making food at all, Zhao Zhen looked at Cai Boyu sympathetically, this crystal elbow is a little black, how can anyone's crystal elbow use brown sugar?

I am not much better, a shortbread in my hand, a little mushy on the outside, I am afraid that I will pick out the best-looking one from the pot, and the shortbread is made of unheard of peach blossom filling.

Sancai tasted a bite and almost didn't spit it out, although it was not delicious, but it was "non-toxic and harmless", and it could only be handed to Zhao Zhen tremblingly in Zhao Miaoyuan's eager eyes.

Anyway, from the beginning of passing through the back hall to the backyard of the Horse Mansion, the shortbread that was not the size of a palm was almost not reduced in Zhao Zhen's hands, Zhao Miaoyuan left with resentment, and Cai Boyu breathed a sigh of relief: "Finally left, the official family is not delicious, forget it, give it to the three talented officials to eat......"

Zhao Zhen nodded in agreement, and as a matter of course, he handed the shortbread in his hand to Sancai and said: "This is the craftsmanship of the princess of Qin, and it is also my imperial gift, and it cannot be wasted......"

In fact, Zhao Zhen understood that the reason why Zhao Miaoyuan left was not because she was angry, but because it was inconvenient for her to enter the backyard, although this was part of the Horse Mansion, but the things inside were absolutely confidential.

"All these you asked for from the Privy Council? How could Di Qing be willing to give? ”

Zhao Zhen's words made Cai Boyu smile bitterly: "Weichen passed on Di Qing, not only did he not give it, but also scolded Weichen, this is what the minister asked from Peng Qi, but they are just some retired soldiers, Di Hanchen is too stingy, and in the end it is Peng Qi's siege!" ”

Zhao Zhen was silent for a while, and finally said: "Di Qing is for your good, Peng Qi is afraid that you will hold a grudge, and he can't give up his love for many years, you still give me a good deal in this kind of officialdom in accordance with the regulations, so as not to be talked about, and there are only a dozen or so guards on the left and right." ”

Cai Boyu said with a smile: "How can this kind of trivial matter trouble the official family, isn't it important for the official family to marry the Tibetan family...... In fact, it's not a dozen or so guards, but a hundred or so ......."

"One hundred and ten?!" Sancai suddenly raised his voice, screamed and looked around: "Cai Boyu, you are really a thief!" One hundred and ten guards are all rationed like this, and it costs thousands of dollars to say the least, what do you want to do?! ”

Cai Boyu was taken aback by Sancai, and then said to Zhao Zhen: "Official, if you didn't need so much before, but you let the minister study this steam engine, the more you study, the more you find that it is extraordinary, if it can be used well, our factories in the Great Song Dynasty can be installed, then it will be different!" ”

Zhao Zhen knew why Cai Boyu was nervous, and nodded slightly: "One hundred and ten is not much, but Sancai means that you, the hundred and ten guards, should be sparse to me, if there is a next time, I will not spare you, Duan Feng, tomorrow you will drop some more people from the Guards Division, as long as the steam engine is in the Horse Mansion for a day, this backyard will be guarded like a prison." ”

Duan Feng, the guard, bowed down and responded: "The last general will obey the order!" ”

When Zhao Zhen entered the backyard of the Horse Mansion, he realized why Cai Boxi was so nervous, this huge garden was ruined beyond recognition, all kinds of iron parts were thrown everywhere, the casing hung on the beams of the pavilion was full of oil, and the huge boiler was placed in an even larger pit, which should have been a good pond.

The huge boiler was constantly burning, bursts of black smoke were spewing out of the chimney, and a black person was constantly adding coal to the boiler, Zhao Zhen found the embroidery of the official uniform from his dirty clothes, obviously this is a high-grade craftsman.

Suddenly, the person who was adding coal stopped what he was doing, looked at the pipe extending from the boiler and kept checking, and Cai Boyu shouted on it: "Master Zhao, what's wrong?" ”

"It's already at the maximum, if I unscrew the gate and don't explode later, it's almost ...... over there"

Zhao Xiaowu, who could only see a mouthful of white teeth, raised his head and replied, his appearance startled Zhao Zhen, and also made Cai Boyu shocked, and the above said that the gate would not explode when the gate was opened?

It's like, maybe, maybe, it's going to explode!

"Official, it's not very stable here, let's avoid it for the time being, right?"

Zhao Zhen nodded slightly, it is really like this, the power of the boiler explosion is amazing, the boiler is a closed container containing water and pressure, when the steam pressure in the boiler is greater than the tensile capacity of the boiler shell, an explosion accident will occur, causing serious destructive force.

With Zhao Zhen's poor knowledge, everyone knows that when the boiler explodes, the steam drum bursts, and the pressure inside the boiler suddenly drops to the same atmospheric pressure as the outside. In the case of pressure reduction, the high-pressure steam in the boiler expands rapidly, and the water with a very high temperature also immediately becomes high-temperature steam, which is quite harmful to people.

"It's so dangerous, what can happen to Zhao Xiaowu's life?"

As he was talking, Zhao Xiaowu climbed up from the big pit: "Thank you officials, Weichen has his own way, connected to the rope and the gear, the gear controls the valve, as long as the rope is pulled, the valve can be opened, so that the steam inside drives the device, so that there is an invisible force, that is, the power of steam." ”

Zhao Xiaowu's words were simple and easy to understand, even Sancai could know the basic principle of the steam engine, and asked with a little surprise: "So it means that the fire boils the water, and then the water turns into gas, and the gas pushes the device?" ”

Not only Zhao Zhen was surprised, but even Cai Boyu and Zhao Xiaowu looked at Sancai in surprise, they didn't expect that he, a eunuch, could say such a complex thing as a steam engine so simply, and it was easy to understand!

Zhao Zhen suddenly laughed: "You are really in a word!" It's just like you said, but the truth is simple, but it's not easy to do what you say, it's as difficult as heaven! If not, why did he Cai Boyu do it for so long? Not always yet! ”

Sancai nodded again and again: "What the official said is that the slave maid just listened to an ear and talked casually, just like a blind man touching an elephant, and he couldn't be reasonable!" ”

Zhao Zhen waved his hand to Zhao Xiaowu and said: "You continue, this is the charm of Gewu, success is to continue to accumulate experience, so as to gain knowledge and experience, only in this way can you improve in Gewu!" ”

Hearing Zhao Zhen say this, Zhao Xiaowu pulled the rope without hesitation, only to hear a sound of blinking, followed by the sound of squeaking, and the sound of collision when the metal shakes......
