As the lavender-haired woman gradually approached, Saihao suddenly felt a cool air approaching, this breath is different from others, the breath is actually a statement of the degree of heat, but it is mixed with the ability to actively regulate its own cellular state and homeostasis, as long as it is a living organism, there must be temperature in the body, and the heat emitted from the body is called breath.

The breath emitted by ordinary people is colorless, so it is generally invisible, and if the three clans do not enter the combat state, the breath is also colorless, and the breath emitted by themselves is invisible, only visible to outsiders.

And there is a big difference between these, and that is the difference between homeothermic organisms and ectothermic organisms.

Thermostatic organisms, that is, representatives of warm-blooded organisms for mammals and birds, have a relatively complete thermoregulatory mechanism, and can maintain a relatively stable body temperature in the case of environmental temperature changes, so that the body temperature does not change due to the external environmental temperature and remains relatively stable, and the breath emitted is mild, of course, this is under normal circumstances, and the temperature of the breath will change during the battle.

Ectothermic organisms are often referred to as cold-blooded organisms, which means that snakes and plants are cold-blooded, and they do not have their own mechanism to regulate body temperature, but can only rely on their own behavior to regulate the emission of body heat or absorb heat from the external environment to increase their own body temperature. When the temperature of the external environment rises, their metabolic rate increases, and their body temperature gradually rises, so they passively leave the unfavorable environment; When the temperature of the external environment decreases, their metabolic rate also decreases, and their body temperature gradually decreases, so the breath they emit is either cool or warm.

However, these two are completely different from the Ice Clan and the Corpse Clan, the Ice Clan is completely exuding cold air, the Ice Clan is a race from the Ice Star and the Ice Star, the Ice Star lives on the Ice Cream Man, the Popsicle Man, etc., which seem to be individuals made of ice, and the creatures on the Ice Star are no different from people, they are all creatures that exude the breath of ice.

The corpse clan is even more incredible, with the appearance of zombies or zombies, but living creatures, with human nature, rationality, sensibility, etc. are no different from other creatures, but the breath they emit is called corpse gas, which is a kind of cold air, and the biggest difference with ice gas is that the cold air makes people's skin feel cold, and the cold air makes people's internal organs cold.

The universe is so big that there are no surprises.

When these two anomalous populations were discovered, in order to distinguish them from the warm and cold creatures, the Joint Headquarters gave them new names such as Ice Clan and Corpse Clan, based on the aura they emitted.

However, the reason why Saihao has a sense of vigilance is because it is summer at this time, and it is still on the street with dazzling sunlight, even if it is a cold-blooded creature, it should also exude warmth, even if it is an ice clan or a corpse clan, he can distinguish between the two breaths, but she is not, there is an eerie feeling in the breath, which makes people get goosebumps instantly.

In short, it was a breath he had never felt before.

Could it be a race in the universe that has not yet been discovered?

Since the establishment of the joint headquarters, they have continued to explore the universe, discovering new creatures almost every day, and then classifying them according to their different breaths.

No matter what kind of breath, they all have one thing in common, that is, the spirit in the breath, in the long-term study of the type of breath, there will be the same inner breath to maintain the harmony of the entire breath, and then it is named the spirit of the breath, and it is determined to be the qi of the universe, but this is also temporarily defined, because there is no species without the spirit of the breath.

The reason why there is the concept of this universe, it is related to the legendary origin of the pearl, with the appearance of the origin of the pearl, there is a rumor, the universe is composed of twelve parallel universes, each parallel universe has its uniqueness and a group of origin beads, but at present, the joint headquarters has not found the universe, and I don't know whether the creatures in other universes have the existence of the will, for the sake of convenience, the inner qi is called the will.

However, Saihao didn't feel the presence of intentional qi in that cool air at all, and he even began to suspect that there was something wrong with his feelings.

The ability to feel the breath is not something that can be felt as long as you know luck, but it takes long-term training, practice and actual combat to understand, and there are only a handful of people who understand the breath in the whole universe, if it weren't for his special background, he might not be able to feel it at all.

Most of them are ordinary people here, and basically no one can feel her coolness, not even Yi'er is noticing, which can explain why she can be so inconspicuous.

But Saihao is not worried about what will happen, although he doesn't know who is coming, but he has no murderous aura, but if there is a little killing intent, he will be subdued by him in an instant, so he pulled Yi'er and walked steadily, without any abnormality.

The girl Shanshan walked over, put her hands behind her waist, smiled sweetly and looked sideways at Saihao, and walked side by side: "Are you the famous Saihao? I am your fan, can you give me your autograph?"

Saihao has a black line on his face, he is famous, what the hell is it? Wear me two feet five...... Forget it, ignore it, let's buy a mask first, if those two people don't have masks, it is estimated that they will not be able to move an inch.

Anyway, where do you sell masks here? Saihao was worried.

No matter how the girl greeted, Saihao was indifferent, the original noble temperament gradually became cheap, she became more and more anxious, and the discussion behind her gradually chattered.

"Hey, hey, hey, why are you like this, I call you!" the girl was anxious.

But Saihao still didn't react......

"What am I talking about, Saihao is not interested in girls. ”

"I'm not interested in girls... Are you interested in men?"

"It's possible... But isn't he holding a delicate girl?"

"Well, this question is a bit hard to explain......"

The conversation was so loud that it suddenly reached the ears of Saihao and Yi'er, Yi'er didn't feel anything, as if she didn't care, and deliberately leaned close to Saihao and held his arm.

But Saihao was depressed, since he met Yi'er again, it seemed that some organ in his body had been opened, he didn't care about anything at all before, no matter what others said, he was indifferent, and there was no wave in his heart, but now he has changed, he always wants to complain about something, he really wants to say, you are only interested in men, but he still held back, no matter how much he wanted to say, it was also a public image, it was better to keep it as it was.

What's more, I don't know what this girl's intentions are to get close to them, and he is still wary of her, but he doesn't want to pay attention to idlers is also his own will, and he is originally a person who is afraid of trouble, so he can ignore it.

There was a burst of laughter from the girls' pile, more mockery.

"People ignore you, you have to talk to you, it's embarrassing. ”

"It's just a nose of ash, see how you end!"

The same goes for boys.

"Girl, don't lick it, you can follow me. ”

"That's right, it's so good-looking, why do you have to practice yourself?

"......Shh

Hearing this, Saihao was still indifferent, he had seen too much of this meeting, but Yi'er was a little touched in her heart, and her expression showed pity.

The girl was a little aggrieved and suddenly felt a little lost in her heart, but she didn't give up, and kept following the two, with a light in the corners of her eyes.

There are fewer and fewer boys and girls watching behind, and the rest are waiting to see how she gets into trouble.

Finally, Saihao saw a sign with a prom mask hanging in front of a store, originally he was reluctant to go in, but when he thought about it, it was so big and there were so many people, in order not to attract attention, masks were essential, forget it, prom masks are prom masks, it's better than nothing, and by the way, you can get rid of the group of people in the back.

After buying clothes early, go home to rest, and go down like this, maybe before you finish buying clothes, maybe the hospital will ......

Thinking about it, his face gradually sank, and he pulled Yi'er into the store with his head down to choose a mask.
