After the hot and cold experiments of water, although Qingqing did not fully understand the principle, the general path was clear: "In other words, air is actually the same as water vapor, and after the temperature drops to a certain level, it can become liquid?"

"That's right!" Tianfang said: "That's the reason! And the volume of air will become smaller, about one thousandth of the original, that is, about a thousand parts of air will become one part liquid, so don't look at this jar, after the liquid inside becomes gas, it will be a thousand times bigger!"

"It's amazing, how do you know these things?" Qingqing's eyes flashed with stars: "It seems that I have never heard of these things before!"

"In our Asgard Palace, these things are all basic things, children have been learning these since they were ten years old, and basically everyone knows the theory now!" Tianfang said, after all, he was the leader of these things.

"So that's the case, then I'll explain it to them, so that they don't continue to spread the word!" Qingqing himself understood, and of course he also wanted to stop the current gossip.

Tianfang waved his hand indifferently: "Don't use this, let them say it, if you stop it, it will be easy for people to spread it even more, and maybe you will be implicated at that time!"

"If you don't stop them, do you want them to continue to pass on like this?" Qingqing was also puzzled.

"It's okay, let them pass it on, the mouth is on their faces, and I can't miss a piece of meat!"

......

In the next few days, Tianfang continued to fill the air, Qingqing seemed to be interested in science, and he came to ask Tianfang about this and that, basically he didn't understand what he said every day, and every time Tianfang explained, something new would appear, and then Qingqing would come over again and again to ask for advice.

Tianfang simply took out a complete set of basic science textbooks and threw them to Qingqing, asking her to learn by herself and read them by herself, and ask questions if she had questions.

Just when Tianfang was living an easy life every day, this Tianqing Qinglai did not ask questions, but asked Tianfang to prepare and prepare, and the Qinglong Emperor was ready to meet him.

Seeing that Tianfang gave him a few clear decisions and planned to let himself lead the way, Qingqing hesitated a little: "Tianfang, you just went to see the emperor like this?"

"Ah, that's it, is there anything wrong?" Tianfang looked at his clean clothes, and there was no problem.

"Isn't this what you should have changed into your clothes?" asked Qingqing weakly.

"No, no, no, that's it, that's it, that's the best, you see Ma Lao going up like this!" Tianfang thought of his clothes that no one could wear, handsome was a mess, but it was too troublesome, so his head shook like a rattle.

......

All the way to the inconspicuous path, Qingqing did not leave this time, but led the way in front, the path looked ordinary, but when Tianfang followed Qingqing to the first foot, he found something powerful.

There is a condensation of soul coercion on the path, and Tianfang clearly feels the huge soul coercion that seems to be devoured by people, and it is estimated that if anyone steps on it without permission, maybe it will be like a bomb immediately. Because of this coercion, the current Tianfang feels terrifying and abnormal, and it is definitely not something that can be stopped now.

Along the way, there was no guard, and slowly walked to the position of the top of the mountain, the top of the mountain was very strange, the conical mountain seemed to have been eliminated by half, and the remaining half was like a cover, the inside was empty, and the conical shell on the outside was retained, and the blue light was shining inside, so that the sky could not see what was inside.

Qingqing walked up with Tianfang and came to this platform that was indeed half a cone, and the blue light was like a barrier, blocking there.

"This is where the Qinglong Emperor is!" Qingqing pointed at Qingguang: "Come with me, the Emperor is already waiting for you!"

Tianfang nodded, followed behind Qingqing, and directly entered the Qingguang, the moment he entered the Qingguang, Tianfang seemed to have been scanned by something, and his whole body, including Linghai and Zhihai, was thoroughly spied on, fortunately, Tianfang found that there was no hostility to this snooping, otherwise something might have happened.

Almost in the blink of an eye, as if it had been a century, Tianfang came out of the blue light, and what caught his eye was not a cave in Tianfang's inference, but a valley with red flowers and green grass: "No, from the outside, there should only be a little space, how can it be so big here?

"This is the realm of the Qinglong Emperor!" Qingqing knew what Tianfang was wondering about: "Come with me!"

"Domain?" Tianfang's eyes lit up, he had seen Ma Lao show his domain before, and found that it was completely different, and in comparison, Ma Lao's domain seemed to be much weaker, but the domain of the Qinglong Emperor was a little fierce, just like a complete world, full of vitality.

Feeling a completely different realm from Ma Lao's sword domain, Tian was relieved to admire, this is really powerful, and Tianfang can hardly feel any incongruity.

"It's almost there!" Qingqing didn't look back, but just reminded Tianfang of the sound transmission, he has learned a lot of things in the past few days, so this time he brought it up Qingqing and tried to give Tianfang some hints, so as not to make mistakes when he got it.

Tianfang raised his eyes and looked at a lump of stool that appeared in the distance, but this lump of stool was blue, and Tianfang knew that this should be Qinglong.

It's a bit funny from a distance, it's indeed a dragon from Earth myths and legends.

"Junior Tianfang greets the Qinglong Emperor!" Tianfang bowed deeply to the right angle according to the method of worship explained by Qingqing at the beginning, and did not bow down.

Tianfang stood in front of the Qinglong Emperor and realized how huge the Qinglong Emperor was, coiled up to a height of dozens of meters, one eye was estimated to be about the same height as Tianfang, and each scale could wrap Tianfang.

If you calculate it this way, a few hundred meters long is proper, and the dragon should have the natural ability to turn big and small, and I don't know how big the maximum can become, and how small the smallest can be, and the myths and legends about dragons on the earth are rapidly turning in the head of the sky.

And the Qinglong Emperor is also looking at Tianfang, compared to the juniors in his own clan, the young palace master of this fairy palace is much better, not only the problem of combat effectiveness, but also wisdom, this is also the strength of human beings, when entering his own domain, Qinglong thoroughly probed this person, the golden primordial god, has been completely formed aura, the field is estimated to be about to reach the prototype, if you really fight with the juniors in your own clan, the same age should not be able to take advantage, but this Tianfang should be slightly stronger.
