Your Highness

Chapter 114 Eat You (1)
But that's not enough!
Xuan Yu's heart was spinning, thinking carefully about the method of making dry ice in the previous life!
At normal temperature and pressure, carbon dioxide is a gas, while dry ice is solid carbon dioxide.In theory, as long as it is lower than its sublimation temperature, carbon dioxide can be condensed into a solid state to obtain dry ice; but in practice, how does general equipment reach this temperature?

At present, dry ice is generally obtained by first pressurizing to obtain liquid carbon dioxide at room temperature, and then using liquid carbon dioxide to evaporate in a low-temperature environment. During the evaporation process, part of the liquid is cooled and solidified to obtain dry ice.

The dry ice machine can be used to produce dry ice, and the raw material for its production is not to use gaseous carbon dioxide directly, but to use liquid carbon dioxide, and still use evaporation to lower the temperature to solidify the liquid carbon dioxide into solid particles; about 40, the liquid carbon dioxide turns into solid dry ice.

The most important thing to make dry ice is pressure and temperature, which means that as long as she masters these two points, she can make dry ice.

The temperature is nothing. After all, there is a big snow mountain on the back of Taixi County, and the most important thing is pressure. How to add carbon dioxide, a gas that no one in this world can think of, in a suitable environment? This is the most important thing!

And if you want to build a dedicated space to pressurize the room, because the room is inflated close to an atmospheric pressure, the continuous outward pressure of the room wall is not conducive to the stability of the room wall.High-strength chamber wall materials are therefore required.Since people's entry and exit affect indoor gas retention, double-layer doors and indoor gas replenishment facilities must be installed.

Thinking in this way, Xuan Yu had some clues in his heart, and he dragged Xiao Nian, who had already had blisters on his feet after walking for another day, back to the post station again.

When Xuanyu entered the county town of Taixi County, she saw a white-haired and childlike old man in a yin and yang Taoist robe suddenly appeared in front of her when she saw the post station from a distance.

"Leave my apprentice?" When Xuan Yu looked at the old man who suddenly appeared in front of her, the old man suddenly said such a sentence.

Xuan Yu was at a loss when he heard the old man's words, "Your disciple? Who is your disciple?"

"My apprentice is Luo Xigu!" When the old man said this, he looked at Xuan Yu with obviously unfriendly eyes. If he hadn't known that Xuan Yu was the man of destiny, the old man would have rushed forward and directly killed him. People were killed.

Hearing the old man's words, Xuan Yu suddenly came back to his senses, his obsidian-like eyes narrowed immediately, Luo Xigu is a half-immortal who can teach a generation of half-immortals, could it be that he is a legendary immortal?It's just that the old man's condescending tone made Xuan Yu feel a little uncomfortable. Even though she had already refused last night, she really didn't want to admit it now that she looked at the old man like this.

"So what if I don't leave?" Xuan Yu smiled lightly, although she felt that immortals are very rare, but aren't immortals also cultivated by mortals, why should she be afraid of him?Moreover, it can be seen from the murderous look on the old man's face when he first appeared, but he did not have any murderous intentions. It can be seen that the old man seems to be scrupulous about something. Few know that there really are gods.This shows that there must be a policy in the heavenly court not to hurt mortals!

"If you don't leave, then you..." It is true that the old man cannot hurt Xuan Yu, but it is possible to do some tricks, so when Xuan Yu looked into his eyes, the old man's eyes flashed, a pair of fine The old man's eyes suddenly looked like two huge whirlpools, almost capable of absorbing a person's heart and soul into them.

In fact, it would be fine if the old man used other methods, so it would be easy to capture Xuan Yu and do some tricks, but he chose the soul control technique, which has been handed down to the Taoist school. The skill is stronger, so when the old man cast the soul control technique, the dark yellow light in Xuan Yu's eyes flashed and he began to fight back instinctively.

The old man's movements were extremely fast, it took only a short blink of an eye from the moment he cast it to the blackness in front of his eyes, and before Xuan Yu could react, the old man fainted to the ground because of the backlash of the soul control technique. Taoism pays attention to the integration of three souls into one soul, but the Wu clan is intensively cultivating the soul, so on the soul, even Xuan Yu, who has just stepped into the Houtian realm, can knock down a Da Luo Jinxian.

Who told this old man to cast some kind of spell that is not good, but he wants to cast something about the soul. Although Xuan Yu, who has practiced witchcraft for two generations, is still just an ordinary mortal, he is extremely powerful in terms of soul. Who let this old man meet? A reborn Xuan Yu.

Seeing that the old man who fell on the road, Xuan Yu didn't intend to step forward to help him because he was Luo Xigu's master, he raised his foot and hurried around, leaving the old man in the middle of the road like that For this, Xuan Yu didn't feel a trace of guilt in his heart, anyway, that old man is a god, and besides, he was backlashed by his own fairy art because he wanted to plot against her in advance!What she did was not bullying him, after all, it would be good if she didn't take advantage of this old man who was fainted when he saw her and beat him up.

The poor old man was knocked down by a mortal just because of a mistake in using the immortal technique, and he was lying in the middle of the road, being run over and over by the carriages that went back and forth without stopping in time!
In the end, the already dark old man lying in the middle of the road and being run over was finally rescued by an old friend who came later.

"I said, old man, are you playing dead, and dare to attack the man of destiny?" Another old man stretched out his hand and slapped the old man awake fiercely.

The old man who was beaten so hard finally opened his eyes slowly. When he woke up, he found that the person standing in front of him was no longer Xuan Yu but his old friend. "Where's the girl doll?"

Hearing this was the first sentence my old friend said after waking up, the other old man suddenly became angry, and dropped another stir-fried chestnut fiercely, "You are so impatient to live, and you still ask that girl! Do you know who the mother of that girl doll is?"

"Who is it?" The instinctive old man took the next sentence from his old friend.

"Of course...it's the supreme empress!" Another old man said in a rage, but he felt that it was wrong when he said the words. He let his daughter go down to the earth to experience it. If he just said that, the empress would know If you do, I'm afraid you will be given a severe lesson.

"Supreme empress, who is it?" The old man looked confused. If it was the saint empress of the two races, there is no need to worry about it, but seeing his old friend's taboo look A flash of inspiration flashed in Er'er's mind, "Could it be that Hongmeng...... Uuuuuuuuuuuu!"
