The area of Hongyi Palace is too large, if you want to use a fire kang according to Qin Ze's idea, it is impossible to use just a fire pond.

What Li Yuan wants is that the entire Hongyi Palace is as warm as spring, which means that at least the heating must be able to reach the entire Hongyi Palace.

With Li Yuan's request, at least a dozen fire ponds are needed. This consumes a lot of charcoal every day, but this is the Imperial Palace, so naturally I don't care about that.

This is a huge project, first of all, the bluestone bricks on the ground of Hongyi Palace must be removed, and then the fire tunnel must be dug out. Either of these requires a huge amount of manpower and material resources.

But fortunately, this is the imperial palace of the Tang Dynasty, and the last thing that is lacking here is craftsmen and materials.

It can be seen that Li Er is very eager, so he directly mobilized all the craftsmen in the Ministry of Industry. They are all the top craftsmen of the Tang Dynasty, and after Qin Ze proposed the fire kang, these craftsmen quickly proposed countermeasures according to Hongyi Palace.

If a fire pit can't be solved, simply repair more, so as to ensure the temperature of the main hall. And these details are not Qin Ze's business, anyway, these craftsmen can do better.

After having mahjong, Li Yuan finally became a lot quieter. This also brought convenience to Qin Ze's construction, after all, no one wanted to work with their heads.

After Qin Ze handed over the matter of the fire pond to the general as a prisoner, he found a good thing in Hongyi Palace.

A natural hot spring eye is located in the southeast corner of Hongyi Palace. The grass here is barren and green, and no one cares about it on weekdays. And Qin Ze also stood on a high place by chance, only to find that there was no snow here.

The hot spring eye is underground, and it is only the size of a borehole. But fortunately, the temperature was enough, Qin Ze tried it, and it was estimated that it was more than forty degrees. And although the spring is not large, the good thing is that the amount of water is large enough.

The reason why these factors were taken into account was entirely because Qin Ze planned to build a hot spring pool here. In this way, even in heavy snowy weather, Li Yuan can come to play in the water.

The hot spring pool Qin Ze also planned to build it bigger, after all, Li Yuan had so many concubines.

Three zhang long and two zhang wide, this size is completely sufficient. Moreover, Qin Ze also divided the pool into deep water area and shallow water area, but whether it was a deep water area or a shallow water area, the deepest place could not be higher than Li Yuan, otherwise if something went wrong, Qin Ze could not afford it.

The deep water area is only about five feet long and only about five feet deep, and the shallow water area is only three feet.

After the pool is dug, the next thing you need is to lay bluestone slabs underneath, and this is also what Qin Ze admires for these Tang craftsmen. With their own hands and simple tools, these craftsmen are able to polish the bluestone slabs that fit seamlessly.

You must know that even in later generations, people could only use cement and the like to achieve this function, but now this craft is like a necessary skill for every craftsman.

The bluestone slabs they paved, even if they were filled with hot spring water, would not ooze a trace of mud. Therefore, it can also ensure that the water in the entire pool is crystal clear.

Moreover, in the shallow water, these craftsmen also built steps, so that Li Yuan sat here, and the water would just cover his body.

Qin Ze found a large number of pebbles around the pool and spread them neatly around. Each piece is extremely smooth, even if you step on it barefoot, there will be no pain.

All the wild grass was dug up, and a large number of precious flowers and weeping willows were transplanted. Winter is not suitable for transplanting, and in this palace, it is necessary to bow to manpower.

Even these craftsmen dug up dozens of plum trees, which looked particularly enchanting in the snow. When it comes to attainments in this area, Qin Ze is obviously not as good as these craftsmen.

Even Qin Ze didn't know how these people could ensure the survival of the transplanted plum in the heavy snow.

But it seems that none of this is difficult for these craftsmen, and in fact there is nothing they cannot do if they want to.

It took only seven days to build the hot spring pool, which is an incredible speed, but no one will be surprised. Because for this pool alone, more than 100 craftsmen from the Ministry of Engineering were used.

Even Qin Ze heard that the stones used to build the hot spring pool were all used by Li Er to repair the palace for him before.

The repaired pool is particularly charming in a snowy field. In particular, the water vapor that is constantly steaming on it is more pleasing to the eye.

The water in the hot spring pool is living water, and one end is connected to the hot spring eye, and the other end is connected to the culvert. In this way, the water in the hot spring pool will flow continuously, and the water inside will be kept crystal clear.

After repairing the pool, he naturally had to inform Li Yuan, and this matter could only be done by Qin Ze himself. There is no way, now Li Yuan is devoted to mahjong, and no one dares to disturb him. What's more, now that the floor heating of Hongyi Palace has been almost built, Li Yuan and them are also full of tricks when they play mahjong.

Qin Ze also went to inform Li Yuan several times, but every time he entered the hall, he lowered his head and didn't dare to raise half a point at all.

This time it was the case again, first standing under the windowsill outside the hall and listening for a while, after making sure that he didn't hear a strange sound, Qin Ze lowered his head and entered the inner hall.

In fact, Qin Ze didn't want to come here, because now Li Yuan and his concubine were playing extremely ambiguously. Without saying anything else, Qin Ze walked in this way, and he had already seen several pieces of dirty clothes on the ground.

They were all clothes of different colors, and they were thrown on the ground so casually, so that Qin Ze also lowered his head for fear that he would step on it.

Li Yuan still looks like that, and a pair of mahjong makes him taste of gunsmoke. Especially every time a card is played, it will be smashed the table. Fortunately, these mahjong games are made of good ivory, otherwise with Li Yuan's gameplay, it is estimated that I don't know how many pairs of mahjong have been replaced

When Qin Ze came, Li Yuan was playing hard, and Qin Ze also stood aside very well, just waiting quietly.

At the beginning, Li Yuan heard that Qin Ze said that he would repair a hot spring pool for him, and he specially explained that he must tell him as soon as it was repaired. It's just that this first time after encountering mahjong, it can only be put back.

Qin Ze stood on the side, whether he walked or looked. I can only keep my head down and try not to listen to things that I shouldn't be listening to.

But Rao was like this, and several robes were thrown in front of him. Fortunately, Li Yuan also took care of Qin Ze, and waved his hand after a round of fighting, letting Qin Ze lead the way in front.

Qin Ze, who got this opportunity, naturally walked out of the inner hall as soon as he slipped through the smoke, and then waited for Li Yuan outside.

The hot spring pool was not far from the inner hall, and as soon as he saw the steaming pool, Li Yuan immediately laughed, and then began to take off his clothes without saying a word.

From this day on, no one dared to approach the hot spring pool within a few dozen feet of the perimeter. Even if Qin Ze had something to look for Li Yuan, he would have to wait for him to come back from the hot spring pool.

Taking a bubble bath every day is good for Li Yuan, playing mahjong in the inner hall all day long, and Qin Ze is also afraid that he will get sick again.

In the end, Qin Ze also deliberately made a pair of tables and chairs dedicated to playing mahjong in the pool, but in this way, the game of undressing could not be played. But this is not difficult for Li Yuan, new tricks will appear soon, so soon the hot spring pool will be within a radius of dozens of zhang, not to mention that no one dares to approach, even if it is walking, it is bypassed.

The renovation work of Hongyi Palace is basically coming to an end, and at this time, the women's team entrusted by Qin Ze to Cheng Huailiang is finally fully organized.

And Qin Ze also deliberately repaired the stadium in Hongyi Palace, and also built a stand. Even in order to ensure the gambling nature of the court, Qin Ze also deliberately made tight clothes for these beauties.

But the obvious effect was somewhat unexpected by Qin Ze, because the tight-fitting clothes outlined the figures of these beauties even more, so this ball game completely became a game of big balls and small balls.

However, Li Yuan looked energetic, standing on the stands, and was already betting with his concubines on who would win and who would lose.

Every time Li Yuan's team scored, he would shout and throw a piece or two of gold cakes off the stands.

It's all made of real gold, and there are two or three taels for each one. And in this way, those Meiji on the court are also working harder. Even in the end, in order to get some more rewards, these beauties began to perform.

For example, deliberately colliding into each other in a strange posture, or deliberately letting Li Yuan's team score.

When he saw this scene, Qin Ze sighed heartily. He didn't even know if he would make Keju even more embarrassing in the future.

But no matter what, Li Yuan is living very happily now, whether it is mahjong or ball games, he has just vented his excess energy. And this also means that it is time for Qin Ze and Yigan to leave.

In fact, those masters of the Ministry of Industry had already left, and the reason why Qin Ze deliberately stayed longer was because he saw the loneliness behind Li Yuan's carnival.

Li Yuan knew that after this time, this huge Hongyi Palace would become his world again. And the only good thing now is that Qin Ze has built this place into a "battlefield", a final battlefield of his own.

Qin Ze is also going to leave after all, Li Yuan knows this. So after a ball game, Li Yuan threw Qin Ze a token and asked him to come and play mahjong with him if he had nothing to do in the future.

At the same time, he also said that when the weather warms up, he will take Qin Ze to see what a real ball game is. When he heard Li Yuan's words, Qin Ze remembered the scene he saw in the inner hall again, and he didn't feel his old face flush at the moment.

Leaving Hongyi Palace, Qin Ze still seemed to be able to vaguely hear Li Yuan's cheers inside. Tightening the token in his hand, Qin Ze walked towards the Li Zheng Palace.

After completing the task and dealing with the old emperor, I have to deal with Li Er.

As far as Qin Ze knows, Li Er is also worried now, Jieli has not been captured for a long time, and the Sixth Route Army cannot retreat for a day. That's a big mouth of blood, and the grain and grass eaten every day is an astronomical amount.

And now as time goes on, Li Er is also getting more and more annoyed. Li Er is not happy, then everyone will be unhappy, and Qin Ze is naturally the same.
