Chapter 786 Green Ice Hibernation Tank

The melting point of iron is as high as 1600 degrees, and so is Qingbing.

Under natural conditions, blue ice is almost impossible to melt.

This means that Qingbing is a stable natural cooling source, which can continuously emit cold air to the outside world, reducing the temperature in the surrounding area.

This feature endows Qingbing with great commercial value and is widely used in the refrigeration industry.

The container carved from green ice can keep the temperature inside the container near the freezing point or even below the freezing point according to the sealing condition.

The open green ice container is commonly known as "refrigerated cabinet", which can store fresh food for a short time, and of course it can also make cold beer.

Covered green ice containers, usually called "freezers", have an internal temperature far below freezing point, which can store ingredients that are not afraid of freezing for a long time, or use the quick-freezing characteristics of the container to make "cream ice cream".

What Qiao An has to do now is to use green ice as a material to make a freezing container for storing insect eggs.

In the sealed green ice container, the eggs will be in a hibernation state for a long time, neither dying nor hatching.

The hardness of green ice is similar to that of steel, but its toughness and ductility are not as good as steel, so it is not suitable for processing by forging.

The general method of processing green ice in the field of magic industry is to throw the green ice raw material into the steelmaking furnace, melt it into ice water at high temperature, and cast it into molds.

Qiao An has no industrial equipment available, so he can only process the green ice container by hand carving.

The knives for cutting and carving green ice must be sufficiently hard.

Ordinary steel knives cannot meet the hardness requirements for processing green ice, but after enchanting the knives, the hardness will increase significantly.

Joan picked up the enchanted dagger "Electric Light Blade" and tried to cut the green ice. There was a rustling sound from the tip of the knife, and crystal clear ice powder fell down the blade.

Joan focused on cutting ice cubes, and spent an hour cutting out a cylindrical embryo. The ice surface was slightly rough, but the size was not bad.

Next, Qiao An patiently hollowed out the green ice embryo and carved it into a cup-shaped hollow container.

After measuring the size of the embryo material with a ruler, Joan took out a large piece of sandpaper to smooth the rough inner and outer surfaces.

After some careful treatment, the green ice embryo material has been reborn into a crystal clear hollow cylinder, which shines cold and green under the light.

Joan brushed off the ice dust on his sleeves, stretched his sore fingers, took out the metal jar containing the eggs, poured the eggs into the green ice container, and then put the ice shell into the jar.

There was a little gap between the ice shell and the tank wall, and Joan stuffed the crushed ice he had just cut into it as a filling to prevent the ice shell from shaking in the tank.

After doing all this, Joan covered the jar and blessed the "secret lock" to ensure that the eggs in the jar would enter hibernation in a low temperature environment.

Putting away the hibernation jar, Joan found a layer of cyan ice dust scattered on the table, so he used a ruler as a scraper to carefully collect the powder and put it into a crystal bottle.

The powder of Qingbing can be used to make preservatives.

Alchemy solutions, magic potions, and blood samples can easily deteriorate if not stored properly.

As long as a small amount of green ice powder is added to these liquids, it can keep fresh for a long time.

Green ice powder is essentially condensed water droplets. Although the temperature is very low, taking a small amount will not cause any harm to the human body.

When Joan left the cafeteria, he brought back the unfinished bottle of vegetable juice, which was now on his desk.

After a busy day, I just wanted to drink some cold drink to refresh myself, so I took a pinch of green ice powder and sprinkled it into the juice bottle, shaking it evenly.

After just a few seconds, a layer of hoarfrost appeared on the wall of the glass bottle.

The juice in the bottle was originally a suspension, and the green ice powder was mixed into it, and there was almost no trace of it. It just quietly emitted cold air to cool down the juice.

The juice was iced just right, and Joan drank it all in one go, belched comfortably, and was very satisfied with this glass of cold drink that he made himself.

...

A series of research around the "giant insect technique" has come to an end.

However, Joan's interest in insect creatures was still unfinished, so he opened a thick notebook and concentrated on reading.

This notebook is an adventure log he wrote down casually during his travels in the Underdark.

Joan intends to extract the content and data about subterranean insects from the diary, and use these materials as a basis to write his first thesis in his academic career.

For the next three days, Joan spent time in the library from morning till night.

Some of the creatures involved in the expedition log, although he has personal experience, these experiences are still mainly on the emotional level.

In order to gain an in-depth understanding of one's research objects, observation and dissection are not enough. One must refer to relevant research literature to find out what research has been done on these subterranean creatures by the predecessors.

During these three days, Joan read the literature eagerly, and read no less than a hundred monographs and papers in total.

In the process of reading, if he feels sympathy for the author's exposition, or induces inspiration, he will extract and record it at will.

Joan's schooling experience was actually quite short.

From Leiden College to Midgard University, it took him less than a year to receive orthodox academic education.

In such a short period of time, his energy was mainly focused on learning the three major subjects of magic, alchemy, and construction.

Master Rawls is a professor who advocates pragmatism, and has no objection to Joan's energy allocation, and his daily teaching to Joan is mainly based on "dry goods" such as making constructs.

As for the ability to write and write, in the eyes of Master Rawls, they are all gimmicky stuff. Nine out of ten papers are meaningless irrigation.

This is not to say that papers are useless, but the most important thing for young students is to be pragmatic. First learn the "hard skills" that can really play and make money after leaving school and entering the society.

As for writing essays and other retreats... It's not too late to do it casually when it's time to graduate and need to issue a thesis mixed with a diploma.

According to Master Rawls's tailor-made teaching plan for Joan, he will not start guiding him to learn the relevant skills of essay writing until the graduation season.

something unexpected may happen any time.

Master Rawls only taught Joan for one semester, but was assassinated in a murder case, and the follow-up teaching plan was aborted.

In this way, when Joan left Leiden College, she had not formally contacted the course of essay writing.

Later, he entered the Advanced Law Research Institute of Midgard University, and chose such a "wonderful" tutor as Professor Moriarty. So far, he has only met the tutor twice, let alone received guidance.

So far, Joan has only read a lot of papers, but he doesn't understand why all papers have to be written in a fixed format.
