The old adobe bricks and the current adobe bricks should be soaked in water on the top of the kiln with cold water before leaving the kiln, so that the fired bricks are dark green in color and particularly strong and durable.

However, the firing of adobe bricks is too troublesome, and it takes a day and a night to make bricks in a kiln, and then people have to stay on the top of the kiln to soak in water. This immersion process is more tedious, not just pouring water on top, you must always keep track of the heat and the amount of water. If the water is used excessively, it is likely that the kiln fire will be extinguished, and the bricks will be burned into stubble. If it is used too little, it will come out of red bricks.

Therefore, it takes at least three to five days for a kiln bricks to be burned down, which is painstaking and laborious. In order to catch up with the work, no one has done it in those kiln factories for a long time.

The bricks used for construction in the town are all red bricks, and it's no surprise that the younger generation doesn't recognize them.

According to Lao Niutou, in the early years, Liu Jiagou not only burned clay pots, but also burned bricks, and this big guy should have been burned at that time. The general bricks will not be so outrageous even if they are burned, at most the bottom part is made of glazed bricks, and the upper layer is good. It can be said that it is rare to encounter this situation in front of me, and it is estimated that when the ground is broken, I forgot to burn paper incense to the land lord, so all the bricks in a kiln were burned. As for the incense burner bowl that Liu Qihua just dug up. It must have been the mud of the time for the land lord.

Those ghosts and gods, the young people naturally don't believe it, but they all know that the older generation believes it very seriously, and although they don't think so, they don't open their mouths to refute it.

"Hurry up and fill in the playground and dig a pit so deep that it will be difficult for students to fall down." Er Mazi saw that it was not a problem for this pit to remain on the playground, and opened his mouth and ordered everyone to fill it again.

When they dug with a lot of strength, now they feel that they don't have much strength when they are hit by the old bull's head. However, filling is much lighter than digging, and in less than ten minutes, the pit is more than half filled.

Dig out such a large glazed brick, and wait for the pit to be filled, and the soil must be pulled outside. Liu Junhao took this situation into account and went back early to pull his cart over to load the soil. There are many people, and the work is done quickly, and in half an hour, the playground returns to its original appearance.

However, as for the whereabouts of this glazed brick, everyone disagreed.

The old bull head meant to find a new place to bury it, but as soon as he said it, the young people spoke out one after another. Dig and fill, fill and dig, without such a toss.

"Xiao Hao, otherwise. Let's pick up the bricks and stand them in your yard as a rockery, right? "Old man Wang loves strange stones, and he thinks that this brick is thick and looks very beautiful. With a little grooming, it's certainly not inferior to those in the park.

"What are you doing in my yard? ...... still occupy the place" Liu Junhao scratched his head, and finally refused. He was quite disappointed now, he had thought it was a strange treasure, but who knew that it was nothing more than a burnt brick. After digging for a long time, only getting a pile of waste bricks, if you want to say that you are not disappointed, you are definitely lying to yourself.

"You ......" Lao Wang was completely speechless, he knew that this person didn't understand art at all, and told him that he was playing the piano to a cow.

"Let's move to the edge of the ditch, it's good to be a rockery," Professor Zhao also thought the shape of this thing was very peculiar.

"Yes, then listen to you two." Anyway, it is better to put it on the playground to occupy a space, and it is good to transfer the next position. After knowing that it was a brick, Liu Junhao had no intention of cherishing it. happened to pull the cart here, so he greeted Liu Qiyong and others to help transport it back.

The six people did not use other auxiliary tools, but only grabbed the edges and corners next to them with their hands and easily moved away. At this time, someone remembered a question: "Why are bricks so light?" ”

"It's purely normal," the old bull head explained with a smile, "After the bricks are burned, the inside is empty, full of bubbles, and I have seen bricks floating on water." ”

Isn't that an iron palm floating on water? A group of people listened to the straight sweat.

Bricks are delivered to the doorstep. Old Man Wang began to plan. According to him, this thing should be placed in the middle of the fire pool, and the scenery is good when there are mountains and rivers.

Of course, before that, you have to go up the mountain to find some stones to match.

Lao Wang wanted to go up the mountain immediately, but Liu Junhao asked him to say that he didn't move, mainly because he was too tired.

"You kid ......" There is no helper, and the old man can only find another opportunity.

Seeing that it was still early, Liu Junhao invited the two into the courtyard to drink tea, who knew that as soon as the hot tea was poured, his mobile phone began to ring non-stop.

"Xiao Hao, a fossil has been found in the village, you hurry up and come over." The phone was connected, and it was Er Mazi's eager cry.

"Uncle Guangxi, don't scold me, I know that thing is a glazed brick." Liu Junhao couldn't answer with a smile. After only admitting his mistake once, he was teased back and forth by the villagers, which was a bit too embarrassing.

"You bear child, what am you doing with me, you really found a fossil. Didn't you dig a lot of black stones when you dug the sweet potato well for me the year before last, and the stones were seen by experts from the city, and he said that they were fossils. You kid hurry up and take a look......"

"Really" Liu Junhao still didn't believe it.

"Believe it or not, you can come and see if you know." Er Mazi hung up the phone directly after speaking.

"What's the matter?" Professor Zhao leaned over and asked, he had just vaguely heard the mention of fossils on the phone.

"Uncle Guangxi said that his family found fossils, and now let me go over."

"Isn't it, he can find fossils in his house?" The two old men also obviously didn't believe it.

"Let's go to the village and have a look." Although Liu Junhao said that he didn't believe it, what people said was clear-eyed, and he still planned to go there. As for the black stones that Er Mazi just mentioned, Liu Junhao remembered them very clearly. At that time, he dug a sweet potato well for his family. When I dug to a depth of more than two meters, I suddenly dug out a large nest of black stones from the soil. Both of them are very strange, this kind of black stone is rare in Liujiagou.

"Could it be iron ore?" Er Mazi thinks about the beautiful things of making a fortune all day long, and when he looks at this thing, he thinks that he may have dug up a vein.

His speculation was not unfounded, and in the early 80s, the province sent experts to inspect this area. I don't know what's going on, not long after the experts left, people rumored that Daqingshan had discovered iron ore, and the province was ready to develop it immediately. Within a radius of more than 10 kilometers, all the people in this area were designated as mining areas, and the people of the entire town were all relocated and relocated to other places. The news spread clearly, and even the amount of subsidy for each family was clear. At that time, the road in Daqingshan had not yet been built, and the news was blocked, and the more this word spread, the more outrageous it became, and many people thought that they would move away anyway, and the crops would definitely be destroyed by then. So he didn't even care about the crops in the field, and waited for the subsidy to be paid from above.

Later, the leaders of the township felt that the situation was serious and sent people to the village to refute the rumors. But even so, there are still many people who still believe that there are iron mines in Daqingshan.

Liu Junhao laughed at him and wanted to get rich and wanted to go crazy, and finally used a basket to pull up all these strange stones. Er Mazi didn't give up, and deliberately took some stones to show the local blacksmith afterwards. When it was clear that the stone was not iron ore at all, he completely dispelled his thoughts.

When they arrived at Er Mazi's house, there was already a large crowd of people gathered there, and they saw the expert standing in the middle of the crowd with a fist-sized stone in his hand and explaining: "This fossil should belong to an extinct marine brachiopod fossil." It is preliminarily speculated to be the 'stone swallow', a creature that probably lived from the late Permian to the early Jurassic period, and is about 200 million years old. Its individual is generally about three centimeters long, and it is a common marine shellfish on the bottom of the sea, and there were many of these creatures at that time, and they cemented each other and became rocks after death. Later, the rocks were weathered, and the shell fossils were stripped and rolled into the dirt and buried in the soil. ”

It's really a fossil...... Liu Junhao found that he didn't know what to say. It is really "intentionally planting flowers and flowers, and unintentionally planting willows and willows". Things twisted and turned, and finally ended in comedy.

He also squatted on the ground and picked up a small stone the size of a coin to observe, when he was digging the sweet potato well, he felt that this thing was sparse and didn't see anything, but now he looked carefully and looked at it for a long time...... I still can't see anything profound. The surface is grayish-black, with a slight bulge in the middle, with some fin-like markings. Other than that, it's completely stone-like. He was now a little skeptical that the expert was fooling everyone, as if he couldn't see the characteristics of the fossil.

"Expert, is this thing worth anything?" As soon as he heard that it was a long time, Er Mazi muttered: Could it really be the ancestor who appeared. He was thinking that he would be able to make a small profit by selling the fossils he had gotten his hands on.

"Hehe, fossils are non-renewable resources, and it is difficult to measure them in terms of money," the expert shook his head with a smile, and then explained, "Shiyan is a common marine invertebrate, and it is a standard fossil for identifying strata. ”

A certain scientific research value means that the value is very low and not worth anything at all. Er Mazi also understood this, but he still didn't give up. Shiyan fossils have been found in many places, but Liujiagou is definitely the only one, and it can be sold as a souvenir.

"This thing, it seems that my family dug the foundation when they also dug it, they are all nests and nests, there are 10,000 of them, at that time my father was still in the way in the yard, and he pulled it into the ditch behind the village with a cart and ......poured it down" At this time, Liu Qihua suddenly spoke, his family renovated the house a few years ago, and dug a lot from the ground.

"No, I also dug it out when I was digging up the vegetable garden, it's exactly the same as this one, I said how can it look familiar" Liu Junqi interjected.

Listening to others, Er Mazi completely dispelled that little bit of caution.

Although the process of discovering the fossils is a bit tortuous. But it's not worth it. Reporter Guo deliberately took a lot of photos before leaving, but he also said that this news is estimated to be very difficult, and at most he will write a newsletter report on the Internet.

Liu Guangju didn't care so much, as soon as he sent the experts away, he grabbed Liu Junhao and said: "Xiaohao, go back and take a few photos with your camera and upload them to the Internet, saying that a large number of paleontological fossils have been found in Liujiagou, and you call on everyone to come here to pick up fossils." ”
