Before Minister Fang said these four words, Yan Feiyang had actually thought of it. It is difficult for him to control the armor by the body temperature to increase or decrease other forms.

"But a person's body temperature is not controlled by himself casually." Yan Feiyang expressed his questions.

Minister Fang nodded and said, "Yes, human body temperature is constant, unless it will rise or decrease under certain circumstances."

Although Minister Fang did not say it specifically, Yan Feiyang also knew what the other party meant by "specific situation".

If it is due to the body, the possibility of body temperature rise is relatively high, such as when you have a fever. However, if it is external force, the possibility of body temperature drop will be greatly increased. There are many possibilities for this kind of external force, after all, physical cooling is still very common.

Yan Feiyang can be sure that the "special situation" that Minister Fang mentioned is what he thought of.

"But these methods will be difficult to achieve for a while, right? And it is also very inconvenient." Yan Feiyang told the truth.

After putting on the armor, if you want to achieve the invisibility function, you must control your body temperature to change at any time. Raising or lowering your body temperature at will is not something you can do in a moment.

If the body temperature fluctuates in a short period of time, it must rely on the help of external objects. However, this becomes very inconvenient. When the armor is worn on the body, you must waste time on the external objects when you want to be invisible.

In this way, even powerful stealth functions will become very useless.

Yan Feiyang believed that changing body temperature was not difficult for him. He could control his body temperature at will, and the height or low was in his mind.

It can be said that as long as Yan Feiyang wants to change his body temperature, he can easily do it. This is because Yan Feiyang has a steady stream of internal force to make the foundation.

He just needs to use his internal force when needed and adjust his body temperature at any time. This is a breeze for Yan Feiyang.

But what Yan Feiyang can do easily does not mean that it is the same for ordinary people. Ordinary people cannot control their body temperature perfectly like Yan Feiyang.

Unless you make a fuss on the armor, improving the sensitivity of the armor may reduce the hard requirements for human body temperature.

However, Yan Feiyang was also a little doubted about how far the secret base had done to the research on the armor.

Minister Fang heard Yan Feiyang's doubts, and he smiled at the corner of his mouth and explained patiently: "Yes, body temperature regulation is not something that ordinary people can do. We have done countless experiments and even spent enough time for them to practice repeatedly."

Yan Feiyang did not have any major reaction after hearing this. He was no longer as hot as anything else, and it was not something that could be achieved by simply practicing. If you have to see the results, you would probably have to keep going day and night, and practice over the years of adulthood to make progress.

Sure enough, Minister Fang sighed and said, "You may have guessed it too. The results are average. We have tried all kinds of useful exercises, but the body temperature still has not changed significantly."

It was consistent with Yan Feiyang's guess, body temperature was a very good direction, but Minister Fang was also causing himself a big trouble.

"I thought I would be able to smooth sailing after solving the biggest difficulties, but I didn't expect that the difficulties would be one after another. But we have reached this point and we can't overturn it here and start over again."

Minister Fang did not complain or be discouraged in his tone. It was this spirit that supported him to persevere for so many years.

After hearing Minister Fang's words, Yan Feiyang couldn't help but feel a little impressed. When he wanted to say a few words of comfort, he suddenly had an inspiration in his mind, as if he had thought of something.

If the body temperature cannot be raised or lowered at will according to the armor, it can be done the opposite. As long as the body temperature is constant, the invisible function of the armor can play a role.

On the contrary, if the body temperature of a person wearing armor changes, the invisibility function will be invalid.

In this way, we will continue to retain the connection between body temperature and invisibility, but we will change the direction of thinking. Simplify complex things and solve the problems.

Minister Fang didn't know Yan Feiyang's thoughts, so he talked endlessly after he opened his mouth.

"We have wasted a long time here, as if we were walking into a dead end and we couldn't find a way out." Minister Fang also felt particularly dark when recalling that time.

Yan Feiyang listened carefully from the side and nodded softly occasionally.

"But God pays off on the people who are interested, and we finally found a solution." Minister Fang's expression eased suddenly, and the smile on the corner of his mouth appeared again, and he continued: "Someone suggested changing his mind, so we changed the relationship between the two."

Yan Feiyang instantly understood the profound meaning of Minister Fang's words. Their ideas coincided.

Fortunately, Minister Fang’s research team is not a vegetarian, and soon realized the problem and had enough time to improve.

In other words, all the latest research results, including the armor on Yan Feiyang's body, have completed the final improvement.

These armors can be completely invisible under the control of body temperature.

Sure enough, Minister Fang's next words once again confirmed Yan Feiyang's speculation.

"We have tried it, and there is no problem this time. It only takes one second to adapt to your body temperature and you can automatically judge the constant temperature standard. Then, according to this standard, the invisible function is collected and expanded."

Minister Fang carefully explained the principle of armor.

Yan Feiyang had already guessed the mystery. Minister Ting Fang said it simple, but he knew very well how much it would cost to do all of this.

However, Yan Feiyang just sighed in his heart secretly. After all, what he cares most about is the invisibility of armor-enhancing.

"Now every piece of armor has remembered the constant temperature of each owner, except for the one you are on. Doctor Yan, the armor has started working during the time you have worn it." Minister Fang said.

Yan Feiyang nodded, he could feel that the uniform was "working". However, Yan Feiyang had already known the principle of armor-enhancing before Minister Fang said this.

So when he was bolting his armor to sense Yan Feiyang's body temperature, Yan Feiyang had already noticed it.

But Yan Feiyang did not make any fuss, nor did he react, and Minister Fang did not even notice something was wrong.

Yan Feiyang just silently adjusted his body temperature in time before the armor was about to work. In other words, he relied on the internal force to increase or decrease the body temperature, and successfully avoided the invisible function of the armor.

Because the armor has already memorized Yan Feiyang's constant temperature value, any other temperature is of no use to it, and it only cares about which value.

If Yan Feiyang's body temperature returns to this value, then the armor will be conditioned and reflexed to activate the stealth function. It only takes a few seconds before Yan Feiyang will completely disappear.

But in contrast, if Yan Feiyang's body temperature has not reached the constant temperature, then the armor will not play any role, and others will never be invisible.

It sounds like that simple principle, but it is really not easy to operate.

However, this does not apply to Yan Feiyang. He can control his body temperature at will, whether it is high or low, all based on his ideas.

"Hmm? It's strange..." Minister Fang said so much, and finally realized something was wrong.

Minister Fang frowned tightly, staring at Yan Feiyang with a sad face, with a look of surprise in his expression.

Yan Feiyang stood calmly in front of Minister Fang, allowing the other party to look up and down. The other party finally realized the problem.

"Why has this set of armor not worked yet?" Minister Fang was a little nervous, with a puzzled tone, as if he was talking to himself, and said: "Impossible. This set of armor has been tested countless times, so there is no problem."

Minister Fang kept muttering, frowning, not knowing where the problem was this time.

"Don't worry, Minister Fang, there is no problem with armor-punching. I am controlling my body temperature. If you don't believe me, you can try it." Yan Feiyang said as he took the initiative to extend his hand to Minister Fang.

Minister Fang became even more confused. He was a little confused, but he subconsciously stretched out his hand and held Yan Feiyang's.

"So hot!" Minister Fang couldn't help blurting out the next second when he held Yan Feiyang's hand, and his hand quickly pulled back.

After a few seconds, Minister Fang immediately reacted, lowered his head and thought for a while, then looked up at Yan Feiyang's expression and the armor on his body.

Minister Fang, who had realized the suddenness, relaxed his eyebrows instantly, and said, "So that's the case! I just said that this problem could not occur. But Dr. Yan, why are your body temperature so high? Are you uncomfortable?"

Minister Fang, who confirmed that there was no problem with the armor, had just relaxed for a while and immediately realized that there were more serious problems.

Yan Feiyang's body temperature would not rise to such a high for no reason. He could only think of a possibility that something was wrong with Yan Feiyang's body, so his body temperature would rise.

But when Minister Fang recalled the touch on his hands, it was not like the temperature of ordinary people's fever, and Yan Feiyang's hands were ridiculously hot.

Minister Fang, who was more confused, could only look at Yan Feiyang and wait for the other party to answer him.

"This is not difficult. You can try again now." Yan Feiyang's mouth was filled with a faint smile, and he was not in a hurry to explain, but reached his hand in front of Minister Fang...

Minister Fang looked at Yan Feiyang in confusion, but he was not able to refuse Fang, so he had to extend his hand and hold Yan Feiyang together again.

Minister Fang is ready to be scalded this time. He feels that the touch on his hands just now can be described as "hot".

He reached out his hand carefully and contacted Yan Feiyang's hand carefully, but Minister Fang's expected "hot" did not come.

"What's going on? Why is it so cold this time?" Minister Fang was even more surprised this time.

Minister Fang stared at Yan Feiyang without waiting for Yan Feiyang to answer, trying to see something from the other person's face and body.

This is too strange. It was so hot just now, but why did it get cold in just a while? (To be continued.)
