Xue Weiyi was surprised: "There is such a strong gas? ”

Qin Guan: "Of course there is, in terms of our knowledge of the college entrance examination, on this planet, there are at least a dozen elements and compounds that can corrode metals. ”

"Oxygen is also a type, but it corrodes very slowly. ”

"Yes."

"I wonder what elements are in the ice crystals?"

"Maybe it's an unknown element that we don't have on this planet. It's not easy to judge. ”

"Sulfuric acid?" Xue Weiyi asked. He doesn't know much about it, so he asks if he doesn't understand.

Qin Guan shook his head: "It's not like sulfuric acid can corrode skin and muscles, but their bodies are obviously not injured in any way. ”

Morning Throw: "Several strong acids can all be eliminated. ”

As he spoke, Dongmen Youfu brought two sets of broken armor and a few ordinary light knives.

Qin Guan threw these equipment and light knives to Cang Yu and asked them to stick them on their bodies to try.

Sure enough, the broken armor and light knives were quickly corroded!

"I'll go, what element is this?"

Everyone was amazed.

In general, when an element corrodes a metal, there is a chemical reaction, such as the exchange of electrons between each other, and the corrosion stops when all atoms are involved in the reaction process.

That is, one side is exhausted.

"But this element is fierce." Qin Guan was thoughtful. "They flew through the ice crystal belt, and the people in the spaceship did not directly contact the ice crystals, but later they were stained with some gas, and the whole body was already like this~~"

Dongmen Youfu asked in surprise: "Will this gas spread and corrode indefinitely, and will it also corrode all the metals in this space world?" ”

"It shouldn't be, it should always have an upper limit......" Qin Guan said this, but he also chuckled in his heart.

Dongmen Youfu said again: "Will it corrode the big screen?" And so much equipment in our warehouse. ”

Chen Zhuofei said: "There is also the iron horse of the material exchanger~." ”

Qin Guan rubbed his head, thought for a while, and hurriedly said: "Quick, Cangyu, don't stay here for a long time, I'll take you to another map, rinse it with water first!" ”

"Also, the big screen is the main body, so it shouldn't be corroded, in case it is corroded...... Leave it to fate. ”

Qin Guan asked Cang Yu to stand a little far away from the big screen, he clicked on the map, took all the team members, and teleported to Tang'an City three years ago.

The foothold has long been turned into a safe zone, and now every time you come there is almost like shopping.

"On the first floor of the commercial plaza, there are water pipes."

"Plastic should be corrosion-resistant."

Zang Gong quickly ran upstairs, and got a few large plastic bags from somewhere, and several people put the three of them into big bags and brought them into the mall.

"This map refreshes every time you enter or leave, so even if the gas escapes, it probably doesn't matter." Qin Guan said,

"Quick, go get a few more large plastic boxes, seal all the things on their bodies, wrap all the metal equipment stained with unknown elements in large plastic bags, wrap a few more layers, and then seal them in the boxes, and send them back to the Ministry of Science for scientists to study and analyze!"

Qin Guan commanded several people.

stared at Cangyu again, and asked them to unload all the equipment on their bodies and seal them all.

"Moon."

……

In the main world of the Grass House.

After Qin Guan left with all the team members.

Changfeng, a material exchanger, appeared in front of the big screen and walked unhurriedly to the place where Cang Yu had just stood.

This time, he didn't lead the iron horse, but held a large vacuum cleaner-like device in one hand and a detector in the other, aimed at all the places where the three of them had just stayed, including inside and outside the villa, and carefully cleaned it up, sucking out all the gas.

Then he used the detector to test it again, and confirmed that it was cleaned up, and there was no "unknown" element left, and then he breathed a sigh of relief.

"Huh, it's really nerve-wracking, it's too much trouble for the system, if you don't make a move, I'm afraid that the iron horse will also suffer."

"Those few Rongjiao Clan Awakened are also shit luck, flying around, and they can actually encounter rare elements! And they don't know anything about it! ”

"But plastics do block gas diffusion to a certain extent and prevent metal corrosion."

"I don't know if those humans can develop compounds that resist moisture...... There should be hope that, with their current level of technology and cognitive ability, there will be at least several options. ”

"We'll see."

"It's getting more and more interesting, and perhaps, the universe also favors this self-reliant human civilization. So grant them good luck and opportunities. ”

"The gods of the Dimen are above, and the universe is above."

"Later, I'll have to let the working program of the map of Tang'an City clean up the ...... over there."

Changfeng took the equipment to clean up the gas, and left in style, and his figure disappeared and disappeared.

……

Map of Tang'an city three years ago, inside the commercial plaza.

Qin Guan stared at Cang Yu: "Quickly unload the equipment on your bodies, remove them all, and don't leave a single thing." ”

Cangyu is all shy, this is a shame!

Zang Gong's face sank, and he turned around and said, "I'll avoid it for a while and see if there are more large plastic boxes." ”

"Okay."

Reluctantly, the three of them unloaded all their equipment and clothes.

While taking off, he carefully stuffed it into a thick large plastic bag, and then took it from the east gate, wrapped it layer by layer, and sealed it in a plastic box.

Then I saw that Chen Zhufei didn't know where to find a long plastic water pipe, one end was connected to the faucet, and the other end was pinched flat, aiming at Cangyu.

"Are you afraid of the cold?"

"What?" Cang Yu was very confused, why did he ask this question.

"I mean, is it possible to catch a cold in a cold shower at more than 10 degrees?" Morning Throwing Fei asked.

"What's a cold?" Cangyu expressed confusion, and then said, "We can tolerate low temperatures, it's okay." ”

"Then I'm sorry."

Cang Yu didn't understand again: "What? Huh? ”

Chen Toufei didn't explain much, and gave the three of them a piece of soap each.

"Wash, wash clean, don't have any residues."

Then he picked up the water pipe, turned on the faucet to the maximum, and took a bath in front of the washstand on the first floor of the commercial plaza.

Don't be afraid to get dirty and messy, because this map will refresh every time and return to the same as before.

Cangyu: "......"

Qin Guan is on the side of the black line of the half of his head, this is simply a means of dealing with prisoners~, but only in this way can the things that are left on them be washed away in the shortest possible time.

Fortunately, the Rongjiao people have rough skin and thick meat, and a little cold water is completely drizzle for them, it seems that ~ is it quite pleasant?

Not far from the side, Xue Weiyi and Dongmen Youfu used seven or eight large plastic boxes, with a very rigorous attitude, to seal and sort out the broken and eroded cave equipment unloaded by Cangyu Triangle layer by layer, and sealed the edges with airtight tape, and sealed them tightly.

After that, he took a few random metal objects nearby and pasted them next to and on top of the plastic box to observe whether the gas in the box would diffuse and seep out.

Just a humble little experiment.

More than ten minutes later, several metal objects were still intact with no signs of corrosion.

"It seems that the compound 'plastic' developed by us humans is indeed immune to the erosion of this unknown element."
