Chapter 663 The ringing sand in the stone forest

But when Bailixiu heard that the Kunpeng's artificial intelligence told Bailixiu that the Kunpeng's freezing technology used freezing light to freeze ingredients.

Rather than the quick-freezing technology used in the world before Bailixiu traveled through, liquid nitrogen, liquid ammonia or air conditioning was used for freezing.

Although Bailixiu has heard of this kind of laser refrigeration technology, it has never been actually applied. Unlike laser heating and laser cutting technology, such technology was common in the world before Bailixiu traveled through time. All already exist.

For example, laser eye surgery, such as laser cutting, laser welding, and even laser anti-missile weapons, etc., laser freezing technology has appeared but not at all. Of course, there have been theories and laboratories about laser refrigeration. The principles and implementation methods.

From a microscopic point of view, temperature is actually the intensity of the movement of atoms. The higher the temperature, the greater the intensity of the movement of the atoms. The lower the temperature, the lower the intensity of the movement of the atoms. If it reaches absolute zero, then the intensity of the movement of the atoms will be The situation shown is that it is stationary. Of course, absolute zero is the same as the speed of light. It can only be infinitely close but cannot be reached.

Laser cooling actually uses the Doppler effect to allow photons to selectively impact moving atoms in reverse direction, reducing their kinetic energy, thereby achieving the cooling effect.

So if you place laser devices on the left and right sides of an atom, let them emit laser photons of the same frequency toward the middle.

If there is an atom in the middle at this time, and it has a speed moving to the left.Then in the eyes of this atom, the photon on the left will be blue-shifted and the frequency will increase under the Doppler effect; while the photon on the right will in turn be red-shifted and the frequency will decrease.

If the frequency of the initial photon happens to be slightly lower than the absorption frequency of the atom (similar to the photoelectric effect, only photons exceeding a certain critical frequency can be absorbed by the atom).Then the frequency increase caused by the blue shift may cause the photons on the left to exceed this critical value and be absorbed by the atoms.The red-shifted photons on the right are even less likely to be absorbed because their frequency is further reduced.

In other words, photons and atoms will only collide head-on and cannot rear-end.A head-on collision will obviously reduce the speed of the atoms, thus bringing about a cooling effect.

In 0.00024, scientist Steven Chu successfully reduced the temperature to [-] K through this laser refrigeration method. For this reason, Steven Chu won the [-] Nobel Prize.

Of course, Kunpeng's laser refrigeration technology may be similar in principle, but the method to achieve laser refrigeration is definitely more mature.

Of course, the advantage of cooling food quickly is that the moisture in the food can produce small ice crystals, or no ice crystals at all. For example, supercooled water is a type of water that although the temperature is lower than the freezing point of water, does not produce crystals and still remains. Keep water in liquid form.

And since the freezing laser is aimed at freezing at the atomic level, the freezing speed is naturally extremely fast, so it can naturally cool the object quickly, so that the ice crystals in the water are formed relatively small, or even so small that they can be ignored.

Of course, Baili Xiu could only lament the terrible technology of Super Play Space.

After a delicious breakfast of scorpion claw meat, the group naturally hit the road again.

Under the protection of the five star-level powerhouses Bailixiu, Ah Ke, Xiao Qiao, Yao, and Zhong Wuyan, the joint caravan's convoy encountered many demon species and monsters in the Yunzhong Desert. The demonized creatures were neutralized with almost no damage.

So on the fifth day after leaving the Protectorate, Bailixiu and others finally reached their second stop in Yunzhong Desert, a place called the Valley of Mingsha.

Of course, this is what was recorded in the travel notes from many years ago in the hands of the person in charge of the Bailixiu Geng United Caravan, saying that there is a paradise in the desert called the Valley of Mingsha.

However, after following the directions on the map, I discovered that there was no such thing as the Valley of Mingsha, but instead numerous stone forests that stood on the Gobi desert.That's right, what Bailixiu and others saw was not some paradise in the Valley of Mingsha, but a forest of rocks hundreds or thousands of meters high.

It's hard to imagine why there are so many rocks here.

And not only that, after the joint caravan entered the stone forest and walked for almost four hours, they still had not left the stone forest, and they even had a vague feeling that they had returned to the starting point.

So, Baili Xiu activated his knowledge and knowledge and prepared to explore the stone forest to see what the secrets were.

However, after Bailixiu activated his own Haki, he discovered that his Haki, which could detect a radius of fifty kilometers, comparable to radar, was not very effective this time, and could only detect a radius of 50 meters.

The scope became blurry after that. Bailixiu was naturally puzzled by this situation, so she quickly asked Xiao Qiao, Zhong Wuyan, Yao and others:

"What's going on? I feel like my power of knowledge has shrunk a lot. Now I can only detect a radius of 50 meters!"

After Zhong Wuyan heard Bailixiu's words, she pursed her lips and said:

"You're doing pretty well, aren't you! I can only sense movement within a three-meter radius around me now!"

Later, Yao, Xiao Qiao and Ah Ke all talked about the shrinkage of the perception range of their domineering power. Besides Baili Xiu, the best person to bring with them is Xiao Qiao, who can also perceive a range of ten meters.

Of course, with such a comparison, everyone found that their domineering power had basically shrunk by a thousand times.

Bailixiu didn't expect this situation, but after thinking about it, Bailixiu realized that the domineering power had only been lost after they entered the stone forest. So, Bailixiu said to Zhong Wuyan and others :
"Wait a moment, I will fly out of the stone forest immediately to see if it is a problem with this stone forest!"

Zhong Wuyan and others naturally agreed with Bailixiu's proposal.

So Bailixiu didn't think much and immediately flew out of the stone forest.

However, in order to avoid hitting these stone forests, which were hundreds of meters high, Bailixiu also flew vertically upward first.

As the flight distance increased, Bailixiu also discovered that there was a thin layer of fog covering the entire stone forest a thousand meters above the stone forest. However, this seemingly thin fog blocked Bailixiu from flying to where he planned to fly. The idea of ​​seeing through the entire stone forest from high altitude.

However, as Bailixiu raised his altitude to 3000 meters, he suddenly felt a lot more relaxed mentally, so Baili immediately launched his domineering power.

As Bailixiu unfolded his own Haki, he found that his own Haki was scanning around and above without any obstruction, but when he scanned downwards, a jerky blur suddenly appeared. a feeling of.
