"I have a question." As a big player in the shelter, Wu Chen obviously has doubts about the source of "crystalline water": "As we all know, natural sea salt crystals (sodium chloride) do not contain crystal water. How do you extract them from salt crystals?"

"Ahha." Alice 1049, who was obviously prepared, threw a piece of blue crystal the size of "sugar cube" to Wu Chen: "Nu, this is the answer you want."

"Cobalt chloride hexahydrate (CoCl₂·6H₂O)." Wu Chen suddenly realized: "No wonder you can find the ore deposit of crystallization water."

"As you can see, the salt crystals in the Red Sea are rose-colored. It is not difficult to find a striking blue color from it." Alice 1049's answer can explain more details. For example, the salt crystal passage when Wu Chen came in looked very similar to a mine cave, and where did the people on the submarine go. These hidden details must be related to the crystal water.

It should be noted that cobalt chloride is not a substance that exists naturally in seawater, but a chemical substance added by man or entered into seawater due to certain geological processes. The content of cobalt chloride in seawater is mainly affected by human activities, such as industrial emissions, sewage treatment, etc. These activities may bring cobalt chloride into the marine environment.

As the most important sewage discharge pool on the Middle East Peninsula, the "Salinity of Sea Water" before the Doomsday was originally defined as the total number of chlorine contained in 1,000 grams of seawater after the replacement of bromine and iodine in 1,000 grams of seawater with equivalent amounts of chlorine, and the chlorine of standard seawater is 19.381‰).

"I didn't expect that industrial pollution saved humanity." Alice 1049 said a cold joke. In fact, except for cobalt chloride hexahydrate, the natural calcium sulfate content in seawater is about 0.1%-0.2%, forming calcium sulfate dihydrate (CaSO₄·2H₂O), that is, "dihydrate gypsum (raw gypsum)" should not be a problem.

It's just that it's not as eye-catching as the blue crystal.

Satellite images show that there are no raw gypsum ore available for mining in the Red Sea. As for whether there are other seabeds, the reactivated satellites are still scanning.

"So, most adults go out to mine." No wonder Wu Chen didn't see many "famous" characters in the drama, including members of the protagonist group of all generations.

"Prospecting." Alice 1049 also started talking: "Walking through the crystalline seabed, looking for a blue prospector."

"This is a dangerous profession." Wu Chen immediately understood the profound meaning behind Alice 1049's saying "70% of the human body is water". Once these people who go out to prospect, the outcome can be imagined.

After thinking about it for a while, Wu Chen understood why Alice 1049 wanted to "test his quality". It was to use this to determine whether he was a potential partner.

Take out a metal can from the sealing compartment, Alice 1049 smiled and said, "Let's go."

"Okay." Wu Chen nodded happily.

Walk out of the nuclear submarine on the same path. Alice 1049 turned on the camera on his helmet: "A can of crystal water can spread about 100 kilometers. Those B.O.M biochemical beasts will come like sharks that smell blood. The rest will depend on you."

"No." Wu Chen smiled and corrected: "It's not so much a tornado, it's a 'Cyclone'."

The migrant who is safe when encountering water "Cypress" will "rescue" when there is insufficient water. He pulls the roots out of the soil, then curls up into a ball and rolls on the ground with the wind. The wind leads the brave wanderer to scatter everywhere. When it rolls to a place with sufficient water, the ball will quickly open, and the roots will drill into the soil again and settle down.

"No wonder." The castle queen "Raging Girl" Ferosa immediately realized: "B.O.M biochemical beast absorbs all the cross-border dominant genes. So it can roll with the wind like a 'Cyclone'."

"Or we call it the 'B.P.M mutant'." Wu Chen is still used to naming it in his own way.

Before he finished speaking, two black shadows chased the diffusing waterline and landed on the ground with a loud bang, splashing large pieces of salt crystals.

"This is..." The castle queen "Raging Girl" Ferosa finally saw clearly the true face of "B.O.M Biochemical Beast & B.P.M Mutant".

I saw that the shape of a ball of hair seemed to be composed of roots. The fluffy tentacle-shaped roots were covered with sharp stings. In the messy tentacle-shaped roots, an ugly face with twisted facial features could be vaguely seen. I stretched my nose and kept smelling the remaining water vapor around me, and roared in a hungry manner.

The little black bird driven by Wu Chen several times was swept by him, but he ignored it without hesitation.
