Chapter 471 Technology Beyond the Times

Chu Dong didn't quite understand why the weather would change in an instant, a cloudy day needed dark clouds, and the accumulation and movement of dark clouds would take time. He didn't know how to do things like crossing a certain line and the sky suddenly darkened. Could it be here? Is the magnetic field changing so drastically that it can change the weather in an instant?

Now that they have climbed two-thirds of the mountain, there is no reason to retreat. The three of them took out their backpacks from the dirt pit, packed their clothes, and were ready to go on. Chu Dong told Li Hongxian. He winked, and then tapped Zhuge Qiu Shang with his chin, and Zhuge Qiu Shang was suddenly nervous, what is this going to do? Murder and kill?

  Li Hongxian immediately understood, strode up to Zhuge Qiu Shang and said, "Offended."

   After saying that, Li Hongxian put Zhuge Qiu Shang on his shoulders like a cargo, and then the three of them ran at full speed like a mountain top.

As the water rushed to the top of the mountain, there was no longer a good way to go. It would take a lot of time to let Zhuge Qiu go on his own. Moreover, the three of them had been slowing down their progress because of the weak body of Zhuge Yuan. Chu Dong was also tired of it. .

   This time there is no drag on the three people, and the speed of the three people has increased sharply. The weakest Yang Yiqing is already a first-rank martial artist, and it is really not difficult to just climb the mountain.

Five minutes later, the three of them came to the top of the mountain smoothly, and the sky cleared up again in these five minutes. After a few people climbed to the top of the mountain, they found that there is still a cave here. There is a huge hot spring lake on the top of the mountain. Most of the flash floods are caused by the broken outer wall of the lake.

  Li Hongxian put Zhuge Yuan down, and he immediately knelt on the ground and started to retching frantically. Being swayed by Li Hongxian for five minutes, this person might not want to eat for the whole day.

Chu Dong let the three rest in place, and he climbed to the edge of the hot spring lake to observe. This lake is much smaller than Changmu Lake, and its diameter is only about 500 meters. The lake is covered with white mist. It's a bit of a fairyland, but Chu Dong clearly remembered that what Tao Zhong and the others saw after they went up the mountain was not this scene. Maybe Tao Zhong's team lost their way in the torrent, maybe they were confused by illusion.

This lake is like a large pot placed on the level ground, and this pot is full of hot water, all the flood water poured out from a gap in the pot wall in an instant, because the amount of water is too large, it is Almost like a torrent.

Chu Dong followed the traces of the water to find the place where the water was sprayed out from the wall of the pot. Under the cover of a patch of silt and weeds, he saw a sluice that was seven meters in width and two meters in length. It was cast in one piece. Teal black metal.

Chu Dong went up and tapped twice with his knuckles. He found that the gate had a thick coating. Chu Dong scratched twice with his fingernails. The inside of the gate was made of some kind of metal with a density close to that of iron. The blue-black coating with a thickness of about millimeters is a coating technology that Chu Dong has never seen before in this era, which is uniform and meticulous.

  Chu Dong scratched off a little paint on his nails, smelled it first, and then took out a lighter he rubbed out of his hand from the backpack behind him.

  These gadgets are convenient but time-consuming to build. Even if the intelligent brain can control Chu Dong’s hand as stable as a machine tool, it will still be a waste of time, but Chu Dong is also full of details for this time to go to the tomb.

After the powder burned for a while, Chu Dong put away the lighter, and the expression on his face became more solemn. This layer of paint is copper oxide with good purity. Copper oxide is very common, and the surface of copper ware is easily oxidized. That kind of oxide layer It can also protect bronzes and give them some corrosion resistance.

But it is only a very thin layer, and the effect of natural oxidation is very general, but if a higher purity copper oxide is prepared and coated on the utensils, it can have a strong corrosion resistance effect. Ordinary bronze wares will rot for thousands of years after being washed by this hot water, but it will not be after the coating.

Coating is a very common but very important technology in modern times. In short, it is coating. Coating is a solid continuous film obtained by one application of coating. Different coatings can add different characteristics to utensils. Heat resistance, oxidation resistance, insulation, electrical conductivity and other properties can be added to some common materials through coating technology.

Chu Dong has never seen this kind of technology in Da Zou, and if there is, it is only some decorative paint. This technology is obviously ahead of this era. They determined the properties of copper oxide and produced copper oxide of extremely high purity.

  【Complete the overall structure simulation and restoration】

  【There are obvious artificial traces, compared with the traces of flooding, and the water level has dropped by 0.8 meters】

  【This mountain is not a volcano, but the lake water has temperature, and the lake water must flow in from other directions】

  【Overall estimated 3D structure projection completed】

The result of intellectual brain analysis is that there is a channel at the bottom of this lake. This channel leads to the bottom of the mountain. It brings hot water from other places, which is equivalent to a huge water pipe embedded in the mountain, but this has a Very unrealistic point, the water level is too high.

The height of this mountain is the highest peak in the first echelon of the Baiduan Mountains. In the absence of external interference, water will not flow to high places. The water level of the groundwater is at least 700 to 800 meters lower than this lake. Why do dozens or hundreds of tons of water climb to the top of the mountain?

Water flows to high places generally rely on pumps and external forces to work, but this lake has too much water, and it is too high. If there is a way to make the lake water rise to such a height, perhaps the principle of the connector It is feasible, there must be a mountain near here that is higher than this, and the mountain is filled with warm water.

  Because Chu Dong always felt that things like pumps were unrealistic, Da Zou didn't have such skills, and he couldn't support it for a thousand years.

   [It is recommended to first explore the bottom of the lake to determine whether it has a passage]

   "Okay, then I'll take a look."

The lake water is very turbid, dark brown as a whole, and it is impossible to see what the bottom looks like. Chu Dong asked Li Hongxian to hold on to his upper sling on the shore and then go into the water to see it himself. It can move freely, exert force, and even stretch. It is an essential artifact for home travel.

   is that the price of obtaining this rope is a bit high, after all, not everyone can create a ghost.

   "Junior Brother, be careful, this water is so dirty, isn't it poisonous?"

  Chu Dong took off his clothes, revealing the layer of protective clothing that was attached to his body. This protective clothing was like a swimsuit, completely wrapping the human body, but the material was much tougher than a swimsuit.

   He put the clothes in Yang Yiqing's hands and comforted him with a smile: "Don't worry, we were washed by this water just now, and it will be fine. If the rope changes, Xiaohong will also drag me back."
