"However, the energy absorbed by the separation of chemical bonds of water molecules is equal to the energy released by binding, so even if the water is broken down into hydrogen and oxygen and burned again, the energy released is equal to the energy it absorbs, and it will not increase the energy of the fire demon!"

"Yes, this is true in terms of total energy, but from the perspective of energy utilization, the fire demon does not release additional energy for the decomposition of water, just relying on the body's outward radiation energy, it obtains the heat of hydrogen and oxygen combustion, with the temperature of the fire demon's body, on the basis of the hydrogen and oxygen has begun to burn, the energy consumption required to maintain the subsequent decomposition of water is not too large, in general, this idea is not much different from using cooled gasoline to extinguish the fire."

"And in fact, because the temperature of the fire demon is too high, the water can't touch the surface of the fire demon's body at all, and it will be decomposed and burned, or, better, vaporized into steam, and there is little point in cooling down."

"But even if there is water that can stick to the surface of the fire demon's body, it won't have much effect, basically similar to the effect of someone pouring a bucket of liquid nitrogen at minus 195 degrees Celsius on you, but you can be unharmed."

"It's strange because of a phenomenon known as the 'Leidenfrost effect', in which the liquid does not wet the hot surface, but only forms a vapor layer on top of it, which when it is extremely hot, it becomes an insulating gaseous protective layer. Because the temperature of liquid nitrogen is so low, the human body temperature is extremely hot compared to it, so when liquid nitrogen flows through the body, it only passes over the surface of the skin. And to the water, the body of the Fire Demon is definitely an 'extremely hot' surface......"

"Although direct watering is not possible, watering is essentially to reduce the temperature, so I chose a substance that will not be decomposed by high temperature, and a metal material with a relatively large specific heat ratio, and then cooled to -268.8 degrees with liquid helium, in order to improve the heat conduction efficiency as much as possible, the warhead is directly made into a fragile structure, and as soon as it hits the fire demon, it will break into small pieces and quickly absorb heat."

"In addition, in order to prevent the warhead from being heated by gunpowder, a high-pressure air jet is used for launch."

"According to my calculations, each cryogenic projectile bullet is about equivalent to the cooling effect of 70-80 kilograms of minus 50 degrees of ice, and at a rate of fire of 800 rounds per minute, Zhao Yingkong and I sprayed about 60 tons of ice towards the fire demon at that time, but this only lowered the temperature of the fire demon part, and its power was really terrifying."

"As for the cryogenic grenade launcher, it's just a large cryogenic projectile gun, nothing special."

"If you want to lower the temperature, since you use liquid helium to cool the bullets of the cryogenic projectile, can't you spray liquid helium directly at the fire demon?"

"The so-called lowering of temperature, strictly speaking, is energy exchange, so it involves the issue of exchange efficiency, although it is also possible to use liquid helium for cooling, but the specific heat of liquid helium is obviously far less than that of metal materials, the efficiency of heat absorption is a problem, and if you spray cooling gas towards the fire demon, the gas heated by the high temperature of the fire demon will rebound back, forming a gas hood around it, further reducing the temperature conduction efficiency."

"And helium is not breathable, if I spray a large amount of liquid helium, I'm afraid you will suffocate before the fire demon is cooled."

"Then why isn't your cryogenic projectile restricted by the Lord God?"

"That's the most interesting part, maybe if I'm using a cryoray, it won't work......"

Maybe it was because he got the fire demon reward, subconsciously Li Xiaoyi was still very happy, and he was constantly answering all kinds of questions, even if the questioner was no longer limited to the Zhongzhou team, of course, the reason for such relaxation also included that the dried tofu was not there, and the remaining Lord of the Ring natives could not understand what they were talking about.

By the time everyone's questions had been asked, Gunnil was fine, and Nyos fell silent again, presumably stimulated again.

There is not only a Chu Xuan who once counted him to death in the Zhongzhou team, but also a Li Xiaoyi, but it is ridiculous that he swore at the beginning of the Lord of the Rings, "The Nanyanzhou team will become the biggest winner among these five teams."

But as a result, from the beginning of encountering the ring spirit, the Nanyanzhou team kept killing and hurting people, and Richard still came back from the Zhongzhou team, which went to the Moriath Tunnel, and it was the Zhongzhou team that fished people and saved people, and during this time, Li Xiaoyi went from the Lord of the Rings rifle, spiritual power divergence metal, to low-temperature projectile guns, obviously made all kinds of preparations, and obtained great benefits for the Zhongzhou team, can it be that just by virtue of resourcefulness, can it make up for strength and hard work?

However, Neos was still thinking, but found that the Middle-earth team was in a commotion.

"Don't say it, forget it, let me beat you up again!"

“？”

"Shoot, shoot, shoot, you know, you just shoot a lot, shoot fast, you can't shoot at the point, what's the use, and after shooting, you'll be impotent, and you won't have stamina at all."

It turned out that Li Xiaoyi was holding Zhang Heng and fighting, and Zheng Zhan was trying to stop him on the side, "What are you doing here?" Why hit him again? ”

"This stupid guy, I'm a technology stream, and it's hard to deal with the fire demon, but he's an elf archer, so he doesn't have a skill like an ice arrow? Holding the Wind Arrow and the Burst Arrow to shoot the Flame Demon, does he have a hole in his head, did he do his homework in advance? ”

"......" Hearing Li Xiaoyi say this, everyone had nothing to say, but compared to Li Xiaoyi, everyone can't be regarded as prepared, except for Chu Xuan, of course.

It's just why when Li Xiaoyi scolded Zhang Heng, the girls next to him turned red?

In the end, when the Fellowship of the Ring Expeditionary Force encountered the elves of Roslorian, Zhang Heng still had a blue nose and swollen face, and this small injury was not worth using any medical charms......

Except for Jin Thunder, a dwarf who was born to clash with elves, in the eyes of others, elves are still very easy to deal with, and Li Xiaoyi is full of thoughts and the elf queen Galadriel's deal with the Elrogs metal, 3,000 power stones!

However, after arriving at the elven city of Carasgalaton in the Golden Forest, Li Xiaoyi knew that this deal would definitely not be able to run, because he saw that there were shiny beads hanging next to the buildings in the city, and according to Gunnier, "D-level fire attribute energy stones, I'm afraid there are thousands of them here......

Looking at these energy stones, Li Xiaoyi held his chin and considered very seriously, should he raise the price a little, according to the dry tofu, in the Lord of the Rings world, it is called the spiritual power divergence metal of the Arogus metal, but it is very precious, if someone tells you that he will exchange 1,000 light bulbs with you for the "Mountain of Light" on the head of the Queen of England, it is estimated that you will not do it......
