Zhao Huan threw these six pieces of bamboo into the box casually, these six great families are not so easy to deal with.

Iron mines, coal mines, silk, grain, salt, these things related to the basic livelihood of the Song Dynasty, a large part of them were occupied by these six great families, and if they want to move them, it is a major event that affects the whole body, and if you are not careful, it will bring disaster to the people, so Zhao Huan must be cautious at this time.

He was thinking about things here, but Cheng Dafu walked in quietly and said to Zhao Huan: "Your Majesty, Lord Xie Huan asks to see you." ”

"Xie Huan, let him in." Zhao Huan then thought that he had told Xie Huan some time ago about this improved iron smelting technology, if this technology could be made, it would definitely be a great technological change, I don't know if he had successfully experimented with it.

"Your Majesty, Xie Huan." Xie Huan saluted Zhao Huan first.

"Xie Aiqing has already successfully tested the technology of iron smelting?" Zhao Huan asked with a smile.

Xie Huan heard what Zhao Huan said, but he smiled bitterly and said to Zhao Huan: "Your Majesty, it is precisely because of this matter that the minister came to ask Your Majesty for advice. ”

Zhao Huan saw that the expression on Xie Huan's face was a little painful, so he couldn't help but ask, "But what difficulties have you encountered?" ”

Xie Huan said a little helplessly: "The method proposed by Your Majesty should be the right way, but now that the minister has tried countless times, this ore can only become soft, but there is no way to completely melt it into a watery state as Your Majesty said." ”

"Is there no way to completely melt that iron ore?" Zhao Huan asked rhetorically.

Xie Huan nodded, obviously a little discouraged, he is a professional craftsman, although there is no way to completely melt this ore, but he can distinguish that this method of melting iron should be the right way, when he didn't know this method before, it was just that, now that he knows that this is the right way, but there is no way to use it, it is naturally extremely uncomfortable for Xie Huan.

Zhao Huan saw that his face was a little painful, thought about it, and said to him: "The paper is shallow, I still follow you to the scene to take a look and see if I can find any problems." ”

Xie Huan was overjoyed when he heard this, and he could see that Zhao Huan should be very concerned about this matter, and he was just here to forgive his sins, but he didn't expect that Zhao Huan would actually take the time to go to prison with him.

"Your Majesty......" Xie Huan was a little moved and speechless.

Zhao Huan decided that he would never drag the mud and water, and immediately ordered Cheng Dafu to prepare a sedan chair, and then took someone to the general as a prisoner.

"Your Majesty, it's already evening at this time, do you want to wait until tomorrow to go?" Cheng Dafu carefully persuaded at this time.

Xie Huan's face was also tight, he hoped that Zhao Huan could follow him now, but it was about to get dark.

"Tomorrow naturally has tomorrow's things, so let's go now." Zhao Huan said.

Zhao Huan also called Xie Huan to his dragon bowl.

"Your Majesty, the minister is also reckless, just thinking about coming to ask Your Majesty for advice, but ignoring the issue of time." After Xie Huan was called to the dragon, he was quite uncomfortable and kept complaining to Zhao Huan.

Zhao Huan waved his hand and said to Xie Huan: "It's okay, it's actually still early." ”

"I'm afraid that by the time Your Majesty returns to the palace, it will be completely dark." Xie Huan had a look of self-reproach on his face.

"This dragon is inevitably a little slow, if you can have a car, this time and again, you can save a lot of time." Zhao Huan said to Xie Huan.

When Xie Huan heard what Zhao Huan said, his face was dazed, and he couldn't help asking, "Your Majesty, what is this car?" ”

Zhao Huan deliberately wanted to enlighten Xie Huan, the smartest craftsman in the Song Dynasty.

"A car is a car that is propelled by steam." Zhao Huan said to Xie Huan.

These Xie Huan don't understand even more, what is steam? Can it also push the car to move?

Zhao Huan naturally knew that Xie Huan didn't understand, and he continued: "Have you boiled water?" ”

Xie Huan nodded, although this gentleman is far from cooking, but he has occasionally done this matter of boiling water, even if he has not done it, at least he has seen it.

"Whenever the water in the pot boils, it will turn into gas and come out of this small hole, which is called water vapor." Zhao Huan pointed to the small hole on the teapot and said to Xie Huan.

Xie Huan heard Zhao Huan speak, and couldn't help but ask: "What Your Majesty said the minister knows, but what Your Majesty said can push the car to walk, the minister feels a little unbelievable." ”

"This little bit of water vapor naturally can't push the car, but if it's a lot of water vapor, when a lot of water vapor rushes out of this small hole, can it produce a huge force, just like such a pot of water, when it becomes water vapor, you can wash off the lid of this teacup, isn't this power very small?" Zhao Huan asked Xie Huan.

Xie Huan was stunned for a moment when he heard what Zhao Huan said, what Zhao Huan said seemed to make sense, this is an ordinary and obvious thing, but he had never thought of it before.

Seeing Xie Huan who was in deep thought, Zhao Huan did not continue, the principle of this steam engine is naturally complex, as a layman, he naturally does not know how this thing should be made, but he can provide a research direction for the craftsmen of this dynasty, the ancients are actually smart and tight, and the direction is right, it is difficult to guarantee that they can't make this steam engine.

Xie Huan has been thinking about what Zhao Huan said to him, to be honest, the current Zhao Huan seems to have opened a window for him, so that he has a new understanding of the world, this feudal dynasty in order to consolidate the rule, the thoughts of all people are tightly imprisoned, although the study of things is also admired by many people, but it is a lot less imagination, this study of things, on the contrary, has become more of a pragmatic theory.

"Why do people still fall off when they jump, and why can kites fly?" Xie Huan used to feel that he was already a master of the science of things, but now that Zhao Huan said this, he found that he couldn't even fully explain these most basic truths, it seemed that everything was common sense, but it was the reason why he didn't pay attention to these things.

Until it was time to be a prisoner, Xie Huan was still thinking about these things in his mind, Zhao Huan patted him and took the lead in getting off the dragon.

Xie Huan realized his gaffe at this time, and hurriedly got off the dragon as well.
