Late at night, a drone more than two meters long took off from the tractor.

Then, the cabin door of the combat command vehicle opened, and the captain officer led by Li Ming walked into the carriage and watched the operator inside operate.

Yang Ping then got into the car, and at the same time, he also held a tablet in his hand, which was turned on.

"Brig Commander Yang, look, this is the thermal imaging detection information transmitted back, you can check it out."

The captain officer pointed to the plane map presented on the screen in front of the operator and showed it to Yang Ping.

Yang Ping reached out and pulled the plane map smaller, then compared it with the data on the tablet on his hand.

After a few minutes, the comparison was completed, and the data was no different from the data on his tablet. At least the target quality was the same, but there was a slight difference in position.

Looking at such data, Yang Ping frowned.

The captain officer noticed that Yang Ping's expression was wrong and asked, "Brig Commander Yang, is it because the data is inconsistent?"

Yang Ping turned his head and looked at the captain officer and said, "No, it's not because the data is wrong. The data you provide is almost the same as the data on my side!"

After hearing this, the captain officer frowned and said, "Brig Commander Yang, according to what you mean, that is the four people you said you need to look for. Our thermal imaging technology still did not find them. I want to make sure that they have really been waiting?"

Yang Ping said: "It should be nothing wrong. Judging from the information I received, they have already landed on the island, but we have not been able to find their traces from beginning to end!"

The captain officer said: "Brig Commander Yang, it seems that these four soldiers selected by you are not ordinary soldiers. They should be the most elite veterans selected from other troops. I guess they should be soldiers with very rich combat experience and are very good at hiding their own traces. Such veterans will come up with many ways to avoid infrared detection!"

Yang Ping shook his head and said, "If it's really what you said, I'm not worried at all, and I don't even need to use your drones to assist in the reconnaissance!"

The captain officer asked again: "Isn't this the case?"

Yang Ping shook his head directly, and he said: "On the contrary, they only entered the army for less than half a year. To be precise, an officer assigned to less than three months, led three recruits who were assigned to the company. They even had many training subjects completed and could not find their traces, which made me very worried. I would even worry if something happened to them!"

The captain officer frowned even more as Yang Ping said, and said, "Brig Commander Yang, maybe it was not what you thought, maybe they did not land on the island, or they arrived on a small island around. Don't worry, we are expanding the scope of reconnaissance and reconnaissance the possible small islands around us!"

Yang Ping said: "There are no other islands around."

The captain officer said: "Captain Yang, I'd better help with the investigation. Even if there is no collapse in the surrounding area, they can rely on the ship to float on the sea outside the island."

After hearing this, Yang Ping suddenly felt hope. He said: "Yes, what you said is not impossible, so just conduct a reconnaissance on the waters around the island!"

The captain officer nodded, and he turned to the operator and said, "Expand the reconnaissance range and search and reconnaissance the waters within 10 kilometers of the island!"

The soldier in charge of the operation did not reply, and his hands became busy again, while Yang Ping and the captain officer stood behind, without giving any orders or language that affected the operator.

Time passed little by little, and I don’t know how long it took. The national operator turned his head and looked at the captain officer and said, “Company Commander, the sea area within 10 kilometers of the island has been investigated!”

After hearing this, Yang Ping immediately approached and went to the computer screen. He pressed one hand on the operating table and stared at the information on the screen.

The captain officer asked the operator: "Have you found anything?"

The operator said: "Report to the company commander, no abnormal targets were found within 10 kilometers of the island!"

Yang Ping had already seen the result on the screen. He turned around and his whole face became very ugly.

The captain officer said: "Brig Commander Yang, don't worry too much. Maybe they are in a special environment. For example, they are good at swimming, and their current range is underwater!"

This reminded Yang Ping. Yang Ping instantly thought that Ding Yi and Wang Zhijun had very good water quality, but he immediately overturned his thoughts. He said: "It is impossible. The sea water is so cool now. If it is underwater all the time, they will not be able to hold on. Secondly, one of the four of them can't swim, so this may not exist."

After Yang Ping said that, he looked at the captain officer again and asked, "You are a thermal detection expert in this field. Do you know any other way to avoid thermal imaging detection?"

The captain officer thought for a while and said, "Some, the principle of thermal imaging is to perceive human body temperature. As long as you can lower your body temperature, you can avoid thermal imaging detection.

For example, if you wrap a layer of substances that isolate heat on the outside of the human body, I know from the theoretical knowledge that some veterans choose to wrap a layer of mud on their bodies when avoiding thermal imaging, but that method only exists in theory. After all, even if you wrap it in mud, humans will still have body temperature.

No matter how thick the mud is, it is impossible to reduce human body temperature to below 10 degrees.

However, some special circumstances exist, such as thermal insulation, increasing the temperature of the surrounding environment. For example, a large fire rises around you. The high temperature generated by the fire far exceeds the temperature of humans. This thermal imaging presents a hot environment, and it is impossible to detect that there is human beings in it. However, this possibility has not appeared within our detection range now.

In addition to thermal isolation, there is another type called cold isolation. Cold isolation is the opposite of thermal isolation. Brother Leng's condition is that the environment he lives in belongs to a cold world. This ice sea world is in a very large range, just in time to put the heat source within its range, such as a natural ice cave, under the ice layer, inside several meters of snow thick.

In addition, our thermal imaging detection thickness can only reach 4 meters. We still cannot detect the heat source that appears in the 4-meter cold compartment. This means, why can't we detect the thermal images underwater!"

The captain officer's explanation gave Yang Ping a direction. He said: "As you say, if a person avoids thermal imaging reconnaissance, he only needs to dig a pit on the ground. The depth of this pit exceeds 4 meters, it is possible to avoid thermal imaging reconnaissance. Am I right to say this?"

The captain officer nodded and said, "Brig Commander Yang is correct in theory, but if there is no cold source barrier, the approximate depth should be increased a little."

Yang Ping nodded, and he reached out and patted the captain officer's shoulder and said, "I'll have a chance to go this time. Maybe your thermal imaging reconnaissance has not helped us much. It's not too early. You can go back early and have a rest. As for the four people I need to find, I have to go to the island to find them myself. Maybe they are hiding under some possible conditions we are talking about!"

The captain officer responded with a smile, and said, "Brig Commander Yang, if you need it in the future, we are willing to help at any time!"

Yang Ping nodded and said, "Yes, I will definitely do it. I will not send you there in person. Now, I want to gather the team and go to the island to check it out."

After Yang Ping finished speaking, he left. He got out of the car and left no words of farewell.
