In Jiang Xin's view, the Qi breath on Jill's body is extremely special, and every part of the body is distributed with extremely balanced Qi breath, whether it is Jiang Xin's suspicious eyes or the hands that seem to maintain the ice wall.

Using the ability he mastered, Jiang Xin could detect that when the ice wall was born, there was no dry performance of a large amount of water vapor being extracted from the surrounding air and ground, coupled with the fact that there was a little white color due to the presence of bubbles, Jiang Xin guessed that Jill's ability was not direct ice.

If so, it can only mean that his strength is too weak, but those who dare to come to mix in this troubled water, may there be a weak person?

Moreover, Jiang Xin had already suffered a loss in the hands of this guy before.

The killer wants a one-hit kill, but looking at the current situation, does this look like what a killer should be when he is assassinated? This is clearly a scene that only occurs when hunting. And the root cause of this is Jill's ability.

When Jill walked out of the city behind him, Jiang Xin wanted to replicate the assassination action of that night, but before he could put the knife on Jill's neck, this guy seemed to have discovered something, and his whole body was like a big fan.

Later, there was a scene that happened now, Jiang Xin was stopped outside, although he was still in a state of concealment, but it should not be good to launch another assassination in a short time. And until now, Jiang Xin has not been able to completely figure out how Jill found out.

Jiang Xin had some guesses in his heart about the use of Jill's ability, but after all, it was not a fact that could be completely determined, so... This assassination attempt has failed.

With a flick of his finger in the air, the surrounding water vapor, which is difficult to see with the naked eye, suddenly began to converge towards the ice wall around Jill, and in just a few seconds, the ice wall that was originally white due to air impurities began to quickly become transparent.

The air is expelled and the pure ice is as transparent as glass, and at the same time it becomes harder and harder due to the increase in purity and the decrease in temperature, and it does not give Jill the slightest sense of security.

From the moment Jiang Xin began to use his ability to erode the ice wall to gain absolute control over it, Jill realized that something was wrong, and almost at the same moment that the ice wall was out of his control, the air around him distorted.

Temperature, a physical quantity that represents the heat and cold of an object, and is also a concentrated expression of the thermal motion of molecules, extracts the temperature in the air, and Jill condenses the wall of ice, but in the same way, he has the ability to remove the wall of ice again.

The drastic change in temperature only momentarily turned the ice wall back into a clear liquid, then boiled and evaporated in just a second, turning into water vapor and returning to its predators, while the remaining heat escaped, distorting the air around Jill.

"Sure enough, I guessed right, this guy's ability is to control the temperature." Spikes, Jiang Xin couldn't help laughing, and then felt a little strange in his heart: "It's a pity, mastering this ability is only the most obvious use, haven't read a book or other restrictions?" ”

For Jill, Jiang Xinzhi didn't give any disdainful evaluation, Jiang Xin has seen a lot of things along the way, he already knows that sometimes the use of ability will be inherently restricted, just like Yang Thunder can't be as treacherous as Yin Thunder, this is an innate limitation.

Jill didn't know Jiang Xin's evaluation of his abilities, and at this time he was still looking for Jiang Xin's traces.

Changing the temperature of the surrounding environment, Jill wrapped himself in the hot air, hindering Jiang Xin's possibility of entering, but relying on the heat given by the double pupil contact lenses, he couldn't find Jiang Xin's figure at all.

Thermal vision ability is actually a kind of infrared detection ability, relying on the detection of the human body to emit infrared rays to see the location of the person's existence, as long as the temperature of the body can not change, even if it is invisible, it cannot prevent the body from diverging infrared rays voluntarily.

But the premise of this ability is to be able to see people, Jiang Xin is now firmly stuck in a position that Jill can't see, even if he doesn't use his invisible ability, he is a transparent person to him.

With an invisible enemy at his side, but ready to come up and take his life, the psychological pressure brought by this Jill is incomparable, even more than when he was on the street.

"Bastard! You've got what it takes! ”

Boom—

The heat poured outward, and Jill's heart was beating at a high speed, and his breathing was so rapid that the air flow rattled.

Retreating a few meters to avoid the hot air that diffused, Jiang Xin's brows moved slightly, and he stretched out his hand a little, and a wisp of invisible electricity instantly broke through the air with a thunderclap, but before he could get close to Jill's side, there was already an escape phenomenon, and then it was completely disintegrated.

But unlike the colorless electricity, the lightning on the ground like silk threads was not hindered in the slightest, and it smoothly approached the hot gas field around Jill, which was hundreds of degrees full, and it was only possible to get close to this extent, and then it was as if it was blocked by an invisible wall.

The unstable temperature and heat distribution of the air allowed the current to escape Jiang Xin, which made him wonder what means Jill used to stop the approach of Yin Thunder, which should not be something that can be done by simple temperature control.

But at this time, there was no time for Jiang Xin to think carefully about the truth, and at the moment when the thunder and lightning approached the hot air, Jill immediately judged the direction of the thunder and lightning by relying on the sharp perception of temperature and heat.

Subconsciously, without any reason, Jill waved his hand suddenly, and Jiang Xin's position was immediately heated up rapidly, although there was nothing, but the expansion caused by the sharp increase in internal energy alone was enough to cause an explosion.

Boom—

The shock wave exploded suddenly, and at this time, Jill finally saw Jiang Xin's existence through the thermal vision, although he couldn't see his face, but the temperature distribution of different colors was obviously more suitable for his play.

"Die!" The spirit was extremely invigorated, Jill let out a loud cry, his hands clenched suddenly, and at the same time, the heat in the air began to lose rapidly, just in less than a second, it turned from hot air to cold air, and as the heat continued to lose, the surrounding temperature continued to decrease.

By this time, Jiang Xin's assassination plan had completely failed.

But in this way, Jiang Xin knew how he had been discovered by Jill before—the imbalance of heat and temperature!

The temperature of the human body is kept between 36 and 37 degrees, and the temperature of the knife is obviously lower than this value, and the ambient temperature will also be different from these two values.

The reason why Jiang Xin was able to kill someone under his nose before was because he only wrapped himself in a hot layer, and at the same time, he was stuck in the blind corner of his vision.

But if he wanted to kill him, even if Jiang Xin used silk strings, he couldn't do it.

The reason is very simple, the specific heat capacity and thermal conductivity of air are one value, and the specific heat capacity and thermal conductivity of the wire string are another value.

No matter how large the silk string is, it is not air after all, and the temperature changes between the air and the thermosphere around Jill must have been remembered very clearly, and the changes in temperature and heat caused by the silk strings cannot deceive Jill.
