Xu Wen's estimated time was not wrong.

On the first day, the foundation was laid, the second day was dug and the ditch was dug, the third day was repaired and the top of the wall was repaired, and the fourth day was the interior was finalized and retouched, and in the evening, it was basically completed.

With Yan Ji's newly transferred group, they completed the project one day earlier than expected.

The fire burned, and the heat gathered into the house, which was still cold outside, but warm as spring inside.

The fire is not strong and the heat is limited, but it is just suitable for ordinary people's lives.

Supporting each other and walking into the earthen house, the people of Fengchun breathed a sigh of relief, and their bodies also stretched.

The old woman was stunned for a while, then suddenly trembled, her thin fingers grabbed Xu Erlang next to her, and said a word vaguely.

Xu Erlang half-bent over and listened carefully. After listening, he straightened up and whispered, "Fifth Aunt said that this feels like ten years ago. ”

This of course refers to the spring ten years ago, when there was still geothermal heat, and winter can be so warm.

The old people nodded their heads. They all lived in such warmth, the world was supposed to be like this for them, but it started to change at some point.

The people of Fengchun settled down, and although the supplies were still limited, they at least survived the urgent need.

There were still a few days before Yan Ji gave them an explanation, Xu Wen left Xu Xihuai here to take care of it again and deal with some emergency matters, and he took Xu San into Green Forest Town to find Yan Ji.

This era is not a commodity society, where you can buy things if you have money.

He bought those winter clothes in advance because he entrusted Yue Mu Xuan before, and now this batch of goods is more than last time, and it will take a while to contact Yue Mu Xuan, so he can ask Yan Ji first.

There are completely two worlds inside and outside the city of Greenforest Town, and when you enter it, you feel a hot air, and the longer you stay, the hotter it gets, and it feels like you are warming up from the bottom of your heart.

"It's really like a fairyland. Xu San just came in from outside, and he felt particularly deeply. Many times, happiness is contrasted.

"Hmm. Xu Wen felt the same way, and the two of them arrived at the gate of the United Office together, and met the Gu Craftsman Officer who had only dealt with him not long ago.

"Why are you here?" said Gu Craftsman, who remembered who they were, and paused, a little surprised.

"Come to Craftsman Yan, is he here?" asked Xu Wen.

"He's in the Singing Academy, and he should still be there. If you have something to do, I can help too. Although it is not as powerful as Lord Yan's position, it occupies the convenience of geography after all. The Gu craftsman officer smiled slightly, very kindly.

Xu San's heart moved slightly, and he felt that he had a point. Gu Jiangguan belongs to the Stone Hammer Society, he is a local, and he must be more convenient than Yan Ji when he transfers goods and stocks or something.

But he definitely won't make decisions about things outside, so his expression didn't move, just waiting for Xu to ask and speak.

"It's Lord Yan who has an order, let us come to him after we finish our business outside the city. "Surprisingly, Xu asked not to mention the matter of supplies.

"Oh, those spring people have settled down, you guys are really not slow. "Officer Gu was a little surprised.

"It's just a reluctance to stay, and I ask the adults to take the time to take care of it. Xu Wen bowed.

"It should. The Gu Craftsman said no more to them, turned around and left.

Xu Wen and Xu San didn't speak, and after seeing him leave, they walked into the joint office together.

There is a clear distinction in the public office, and people in two different costumes come and go, on one side is the Stone Hammer Society, and on the other side is the Ziyi Public Office.

The former were a little more numerous than the latter, and many of them were sitting or leaning on their feet, chatting and laughing with ease, while the latter were almost all walking at a brisk pace, as if they were one step slower and they would miss a big thing.

When Xu Wen and Xu San entered the door, they first encountered the Stone Hammer Society, but the other party just lifted his eyelids and ignored people.

It didn't take long for someone from the Ziyi Mansion to come forward and ask earnestly, "Where are the two little brothers from?

With this service attitude, Xu Wen felt that he was in another world.

"May I ask if Yan Ji is here?" asked Xu Wen.

"Lord Yan?" the man's expression changed, and he was completely in awe, "He shouldn't have gone out today, I'll take you to the Song Wind Academy." ”

He led the two of them backwards.

The joint office is a cave structure, the city as a whole sinks, and the cave is dug in the rock wall of the basement.

The cave is not dark, and there is a skylight dug above, which is half-covered by a rattan straw window that can be opened and closed. I just don't know what to do when it rains......

Xu Wen glanced upward, subconsciously thought of this, and then asked.

"The windows were designed, retracted to the side, and then a ceramic water pipe was installed to drain the stagnant water. Xu asked them to be his own people, and the person did not hide it, talked eloquently, and explained it very clearly.

"Pottery pipes, fired from the kiln?" asked Xu Wen.

Speaking of which, he had seen this kind of pottery water pipe in the museum before, and it was still the drainage pipe used in China when it was a primitive society. At that time, he was surprised at the advanced level of that era, but he did not expect it to be used to this day.

But think about it, the ceramic water pipe has low precision requirements and poor permeability, as long as there are materials and corresponding geographical environment, it can be said that it is convenient and easy to obtain.

"Yes. The man said succinctly.

"Was it burned nearby, or was it burned elsewhere?" asked Xu Wen carefully.

This is a joint office, and all the people who come in and out are craftsmen. Craftsmen don't care about this kind of problem, so what else do they care?

So the man was not surprised, and naturally replied, "It's burning nearby." There is a Yinshui River ten miles away from this southwest, and there is a laterite mountain by the river, and the clay is produced on the mountain. It's not too good clay, but it's enough to make stoneware. ”

He looked left and right, picked up a clay pot from the side, and handed it to Xu Wen, "Well, this is from the Yinshui kiln." ”

Bricks and stones are not separated, and Qin Lianying's codex has a lot of related content of burning bricks and bricks. Xu Wen has studied it seriously and memorized a lot of theoretical knowledge, but he has not officially put it into practice.

However, Qin Lianying is a senior craftsman in Jingying Mansion, and Xu Wen has studied seriously enough, and this theoretical knowledge alone is enough for him to understand a lot.

Judging from this clay pot, the quality of the laterite mountain clay does look very average. The particles are large and impurities, and the fired pottery is very rough and not very good-looking.

But Xu Wen knocked lightly and found that the sound of this clay pot was crisp and the feel was very strong, which showed that the clay was very sticky and was a high-quality feature.

"Thank you. After a while, he returned the clay pot to the man and continued to walk with him, but he took the incident to heart.

On the way, he said something again, and the man answered all the questions and had a very good attitude.

Xu Wen was mainly concerned about the drainage problem in the outer city of Lulin Town, and the person happened to be familiar with it, and the answer was like a stream.

Xu asked a good question, and the man answered well, and in just a short time, the two even had some hatred for seeing each other.

"Lord Yan lives here, Brother Fourteen, you can come and chat with me when you have time. I am on duty at the office every Wednesday or Friday every month, and you can ask me my name in front of me. ”

When he arrived at an arched doorway, the man bowed his hand to Xu Wen and said heartily.

On the way, the two of them have already known their names, this person's surname is Qiu, his name is Qiu Yueming, a native of Nanyue, and he was also sent to serve, but this is the second time.

He had a bit of a relationship, so he went through the back door and was not sent down, but stayed in the Greenwood Town United Office.

This is a first-class advantage, but Qiu Yueming is still a little simple, and it is even a little embarrassing to say.

But judging from the answers on the road, he does have real skills.

"If Jiang Wangfeng hadn't met you, it is estimated that he would have been assigned to such a mission. After Qiu Yueming left, Xu San said with a smile.

"I think so, too. Xu Wen nodded.

Jiang Wangfeng came from Jiangnan Road, and it can be said that he fell from the sky to the ground. But he's been alive and kicking all the time, and it's really very rare.

The wooden door in front of them was hidden, and the two of them stepped forward together and knocked lightly.

"Come in. Yan Ji's voice came from inside.

Although the geothermal heat in Greenwood Town is warm, it will be a little hot and dry after staying for a long time.

Xu Wen stepped forward and pushed open the wooden door, and a gust of wind swept out of the crack in the door and pounced on his face.

In an instant, the dryness on his body disappeared, and he instantly understood the meaning of the word song style.

In a place like an underground cave, there is such ventilation?
