About 40 kilometers northwest of New Chang'an, there is a group of people walking in the Gobi.

They are quarrymen.

In order to rebuild Poseidon City, a large number of stones are needed, the stone of a stone mountain has been quarried, and millions of electric detonators are more than enough to blow up a stone mountain, and there are many stone mountains nearby, however, the quality of the stones produced by these stone mountains is very poor, the stones are very scattered, and they are not stones, ordinary rocks, the rocks are weathered and can be peeled off, so the quarrymen have to go to other places to find stone mountains that produce marble, granite and basalt.

On a satellite map, the location of nearby stone mountains is marked, and quarrymen are divided into more than a dozen groups to find stone mountains that produce high-quality stones, which are urgently needed on the construction site of Haishen City.

"We are almost there, and it is clear at a glance what kind of rock this stone mountain is made of, granite, marble, basalt and other dense and hard, smooth surface rocks are the stones we are looking for." As the captain of the team, Li Dajun said, "Everyone speed up the pace, after exploring this stone mountain, you can return to New Chang'an before sunset, go back to the dormitory to take a hot bath, and then come to my house to drink." ”

"Yes, Captain."

......

Half an hour later, a group of people arrived at Stone Mountain.

"Captain, it's granite, a very good quality stone." A quarryman holds a rock in his hand, the rock is grayish-white, the stone grains that make up the rock are fine, hard, and the surface is smooth.

Because granite is not easy to weather, the color is beautiful, and its high hardness, wear resistance, as well as granite corrosion resistance, wind erosion, acid erosion in rainwater, etc., can be preserved for a long time, the ruins of Poseidon City under the sea, including the stone made of pyramids, most of the stone for carving statues, the stone for magnificent buildings, and the stone slabs paved on the ground, stone steps, etc., most of the stones are granite.

Li Dajun nodded, "Let's carefully investigate separately, how large the distribution range of granite is, and test whether there is any radon gas overflowing, everyone be careful and safe." ”

Although granite is a good material for construction, some areas of granite can spill radon, a naturally occurring radioactive gas. Radon can cause lung cancer, and 13% of lung cancer deaths in Hong Kong are caused by radon gas concentration.

"Okay, Captain."

......

About half an hour passed.

Li Dajun heard a hurried voice over the walkie-talkie, "Captain, come and take a look, we have made a huge discovery here." ”

"Okay."

......

Li Dajun reached a rocky canyon.

"Look, Captain, there used to be quarrying here." A worker said.

Li Dajun nodded.

Indeed, this was once a huge quarry, and there are still chisel marks and cutting marks on some granite stones, and a large number of broken stones are scattered around, and there is a long crack in the rock under Li Dajun's feet, which is obviously caused by artificial stone extraction.

The ancient stonemasons needed to take a piece of stone, and what would they do, a very clever way, using heat expansion and contraction, first burning fire on the stone, and then, pouring cold water on the stone when it was very hot, the stone will collapse.

If a huge stone needs to be taken from it, it will use the principle of thermal expansion and cold contraction of the rock to artificially form a crack on the rock mass, so as to separate the huge stone from the rock mass.
