Chapter 1515: Solid oxygen ice lake

The first thousand five hundred and fifty chapters solid oxygen ice lake
Zhao Zhongyao heard Feifei's words, and suddenly he tore off the gas mask from his head. Then he looked at his son and laughed.
When Feifei saw his father's movements and expressions, he was stunned. He didn't understand what was going on with his father. He was still very serious just now, so he started joking with him in a while.
‘Dad, what’s wrong with you, why did you tear off the gas mask. Feifei looked at his father with some worry and asked.
At the same time, Tiantian and Qu Yuqian also looked at Zhao Zhongyao in amazement. After all, they were also a little worried. Is Zhao Zhongyao's current behavior clearly a dangerous thing! How can you not wear a gas mask!
‘There’s no problem at all, you can all pull the gas mask! Zhao Zhongyao looked at everyone again and said with a smile.
When Feifei, Tiantian and Qu Yuqian heard what Zhao Zhongyao said, they were all stunned again. They didn't even tear off the gas mask, and still looked at Zhao Zhongyao with puzzled expressions.
‘I said what’s wrong with you guys, do you want to wear a gas mask all the time? If that's the case, just wear it! Anyway, I want to take two more breaths of air with high oxygen content. "Zhao Zhongyao deliberately took two deep breaths while talking.
Feifei, Tiantian and Qu Yuqian saw Zhao Zhongyao's behavior, and then they all tore off the gas mask on their heads.
‘Dad, what did you just say, you have to take two more breaths of air with high oxygen content, what is going on? Feifei completely confused Dad.
Tian Tian and Qu Yuqian were the same, they both looked at Zhao Zhongyao inexplicably, not understanding what he meant by what he said.
‘The light blue gas is not only not poisonous gas, on the contrary it is some oxygen. ’
After Zhao Zhongyao finished speaking, he showed some triumphant eyes. It was as if he had picked up some treasure.
When his wife and children heard Zhao Zhongyao say this, they all looked at him in surprise. After all, what he said was really outrageous. How could there be any oxygen on this moon?
‘Dad, stop joking. How could the light blue gas be oxygen? Feifei looked at Dad with a look of disdain. He couldn't believe what Zhao Zhongyao said.
‘You come and see this. After Zhao Zhongyao finished speaking, he placed an instrument in front of Feifei. After Feifei looked at it, he was surprised. After all, the instrument clearly shows that the oxygen content in the air here reaches 22%. This is a very magical thing. You know, the air composition on this spacecraft is the same as that on the earth. Feifei had already learned about this from his father. Looking at this situation now, he is really inexplicable.
It’s the same every day, she also looked at Zhao Zhongyao with a look of surprise and said, ‘Dad, how can you be sure that the light blue gas is oxygen. ’
‘Because oxygen is in the earth’s air, after being mixed with other gases, it becomes colorless and transparent. In fact, oxygen is light blue. Even if you don't know this knowledge, you should have seen an oxyacetylene flame! Is this oxyacetylene flame light blue? Zhao Zhongyao looked at Tiantian again and said.
Every day when she heard her father say this, she understood what he meant. In this way, the gas in this crater is really oxygen.
How could there be oxygen in the Arctic crater of this moon? This is really incredible.
‘Dad, do you say that this crater is full of oxygen! ’Tian Tian said as he looked at his dad in surprise.
‘It should be like this. Since we saw these light blue gases, there is an ocean of oxygen under the entire crater. Zhao Zhongyao looked at Tiantian and said.
Feifei looked surprised when he heard what Zhao Zhongyao said. He also looked at his father and said, ‘so, the big ice lake below is also an oxygen ice lake. ’
When Feifei said this, Tiantian and Qu Yuqian were also surprised. After all, this matter, you have not thought about it just now! You know, Zhao Zhongyao said before, this big ice lake is two kilometers thick. Think about it this way, how much oxygen should be stored in this ice lake.
After hearing Feifei’s words, Zhao Zhongyao said, ‘it should be the case. Since these light blue gases are all oxygen, the light blue big ice lake is also oxygen. It's just solid oxygen at that time. These light blue gases are gaseous oxygen.
‘Dad, how can there be so much oxygen in this place, this is the north pole of the moon! How could this place produce so much oxygen. Feifei really doesn't understand this question.
‘I don’t understand either, but we can continue to explore and maybe find the answer to this question. Zhao Zhongyao doesn't understand where the oxygen comes from now. Anyway, he felt that if he wanted to solve this mystery, he could only continue to explore.
‘Dad, where are we going to explore, we have not already reached the bottom of this crater, we have already seen this big ice lake. Go there. ’
Feifei couldn't figure it out yet, and now they had reached the top of this big ice lake. Should also go there to explore.
‘We can go and see around this crater. Although we have reached the bottom of this crater. But have we not seen what the surroundings look like? ’
The space under this crater is also very large. The diameter of this crater is nearly 20 kilometers. They descended from the middle of this crater to the top of the big ice lake at the bottom. The searchlight on the spacecraft can only see a few hundred meters around the spacecraft. They haven't seen what other places look like!
‘Okay, let’s go and see around. Feifei heard what Dad said, and nodded in agreement. Because they can no longer find anything valuable in this place, they must expand the scope of exploration.
At this time every day, as if thinking of something, he looked at Zhao Zhongyao again and said, ‘Dad, isn’t this crater a lava skylight! Since this is the case, shouldn't there be many lava pipes inside this crater! We just saw the big ice lake at the bottom of this crater, but haven't seen the lava pipes in this crater yet! ’
After hearing what his daughter said, Zhao Zhongyao nodded and said, ‘what is said every day, if you don’t say that, I would forget about it. I just thought this was a volcanic crater, and I forgot that it was a lava skylight. ’
‘Then shall we go and see if there are lava pipes here. ’He said, looking at his father every day.
‘Okay, let’s go and see. After Zhao Zhongyao finished speaking, he drove the spacecraft again and started flying towards the edge of the bottom of the volcano.
Soon, they reached the edge of the crater. Only at the beginning, they saw nothing but ordinary cliffs.
‘Hey, isn’t there a lava pipe here. Zhao Zhongyao feels very strange. After all, this skylight is supposed to be a lava pipe!
‘Dad, why there is no lava pipe here. Every day is also very strange.
‘It seems that this place is not a legendary lava pipe. It might be an impact crater! Feifei made such a judgment.
Zhao Zhongyao said, ‘No, there must be a lava pipe in it. It should not be an impact crater. If it were an impact crater, it would not be like this. Don’t look at it, we just saw that this crater was very steep outside, almost perpendicular to the surface. This shows that this place is a lava pipe, not an impact crater. ’
Zhao Zhongyao is still very confident about this. After all, he had seen it before that this crater was completely different from the Shackleton crater they had seen at the south pole of the moon. ’
When Zhao Zhongyao said this, Feifei and Tiantian had nothing to oppose. After all, they also saw that this crater is indeed a very different impact crater on the south pole of the moon. This crater is obviously a crater. Since it is a crater, there should be a lava pipe.
‘Dad, if this crater is a lava skylight, then why can’t we see lava pipes? Feifei looked at his father puzzled and asked.
‘No, I think it must be. We just haven't found it yet. The place we see now is just a place on the crater cliff. This crater is very large, and the area of ​​the cliff is also very large. We still have to look elsewhere. Zhao Zhongyao said again.
‘Okay, let’s look elsewhere. Feifei said so too.
So, Zhao Zhongyao flew to other places with the spacecraft. But he flew for a long time, still no results. Looking out from the spacecraft, there are some steep cliffs, and there is no such thing as a lava pipe.
‘Dad, why haven’t you seen the lava pipe yet. Feifei was a little worried. After all, he felt that they had been flying again for a long time and still didn't see the lava pipe.
'Yes! Dad! What lava pipes are there. Every day is also very puzzled.
Even Zhao Zhongyao himself felt very puzzled. After all, they have been flying for a long time, but still can't see any lava pipes.
‘Is this crater really an impact crater! Now even Zhao Zhongyao himself felt incredible.
But at this moment, their spacecraft suddenly began to shake again. At this time, Zhao Zhongyao was a little nervous. After all, they are now at the bottom of the crater. I don't know what's going on below. Although I have experienced the shaking of the spacecraft before. But it was only in the midair of the crater.
But now it is different, they are at the bottom of the crater. They also looked at the cliff at the bottom of the crater just now, and found no traces of lava pipes. But now suddenly there is such a situation, which makes Zhao Zhongyao somewhat inexplicable.
But Zhao Zhongyao himself didn't know what was going on. I don't understand why this place is abnormal. How could it make the spaceship shake again.
‘Dad, what is going on. Feifei is also a little scared.
Tian Tian and Qu Yuqian were the same. When this happened again, the two of them also looked at the outside with some worry.
Zhao Zhongyao himself was a little scared, but he also knew that the spacecraft they designed was very safe. There should be no problems. As long as he can now see what is happening outside.
‘It’s okay! Let's see what's wrong with this place. As Zhao Zhongyao said, he hurriedly manipulated the spacecraft to stabilize the spacecraft.
Then, Zhao Zhongyao drove the spacecraft to fly away. But just after he flew for a while, he felt the spacecraft shake violently. After that, he saw a very amazing picture.
Just beside the cliff, a very large cave suddenly appeared. The entire cave is circular, at least one kilometer in diameter. It's really a very big cave.
As soon as he saw this thing, Zhao Zhongyao knew that this should be a lava pipe. The thing that caused their spacecraft to shake suddenly was the wind blowing out of this huge hole.
‘Dad, why is there such a big hole here. Of course Feifei saw this huge cave, so he quickly said loudly.
Tiantian and Qu Yuqian were the same, they were all surprised when they saw this huge cave. After all, this cave is really too big, completely beyond their imagination.
Zhao Zhongyao looked at the scene in front of him, and he was also a little surprised. After all, he did not expect that there would be such a big cave in this place.
‘This should be a lava pipe. Zhao Zhongyao felt that this huge cave must be the lava pipe of this volcano.
‘Such a big lava pipe! Feifei was also very surprised when he heard what his father said. After all, this lava pipe was beyond his imagination.
Originally, Feifei thought that there should be many lava pipes under this one, and then the size of each pipe might be different. But now they saw that it turned out to be a very huge lava pipe, which surprised everyone.
‘It’s really big, and I never thought that there would be such a big lava pipe under this crater. Even Zhao Zhongyao felt a little surprised. After all, he couldn't expect that there would be such a big lava pipe under this volcanic crater.
Tian Tian and Qu Yuqian also looked at everything in front of them very surprised. Neither of them could understand, how could there be such a big lava pipe in this place.
‘Dad, do we want to look inside this lava pipe. Feifei is a boy, after all, he is bolder. Although he was a little scared in his heart, he still said such words.
