The corpse was not small, the scales on it were the size of a human face, Tenzin leaned in to take a look, and found that the corpse had been dehydrated due to the heat, and it looked very much like the corpse of a dried snake that was used to soak in jars seven or eight years ago.

The only strange thing is that the lizard's head turned out to be a rare three-headed, shriveled head with fangs exposed, eyes sunken into the sockets, and it looked like it had been dead for more than a few years. The only thing that frightens people is that the three heads of the lizard have been cut into a large hole by something, and the inside is empty, and there is no sign of brain tissue in the slightest.

It's a frightening tactic.

"I remember that in Western mythology, it is said that the guard of the gate of hell is a dog with three heads, and I think the god of you Westerners is a short-sighted person, and the guardian of this underground world is clearly a lizard with three heads!" Lu Xiaobu smiled and was talking nonsense again.

We ignored Lu Xiaobu, Professor Yu went to look at the wound on the lizard's head, frowned and said: "It seems that this place is not simple, although it is so hot here, but there is definitely an unimaginable danger, we can't take it lightly just because we have this mecha." ”

"Roger!" We replied in unison.

For the rest of the road, we walked very fast, and there was a large plain outside. There is soft and flat volcanic ash under our feet, and there are some low plants and shrubs around, so we try to step on the place where there are plants to grow and head towards the Divine City, because wherever there are plants growing, the temperature is relatively low, and we can try to avoid the lava rivers that flow from a distance.

Professor Yu told us that there must be an underground river here, and the flow should be very large, otherwise there will be a lack of conditions for plants to survive here, and it will be impossible for plants to grow.

In the distance, the lava was flowing slowly, and the faint light of the fire shone a zigzag dark red on the approaching patch.

Klaus told us not to worry. The temperature of the magma here was much lower than he had imagined.

When I asked him how to tell the temperature of the magma, Klaus explained to me: "On a clear day and with good perspective, the color of the lava flow is related to the corresponding temperature: the white one is the highest, probably above 1150C, and the golden yellow is around 1090C. Orange is about 900, bright red is more than 700 degrees, and dark red is in the range of 550 to 625c. Our vision conditions are very poor now, and we can only see the dark red, which proves that the temperature of the magma here is definitely not higher than 475C. This kind of temperature is no problem for our mecha, even if we walk directly on the magma. ”

Lu Xiaobu heard the conversation between the two of us from the intercom, and interjected: "Xiaoliang, don't believe Lao Ke's words. He's got you! If you're walking on the lava, you'll probably have to recreate the scenes in the classic American blockbusters, and then you don't give me a thumbs up, just a middle finger at Klaus. ”

Klaus laughed when he heard this: "You're talking about the movie Terminator 2, at the end, the T-800 robot played by Arnold Schwarzenegger gave a thumbs up to the future leader John Connor when he finally sank into the magma, and the magma temperature in the film is very high, which is much different from the magma temperature we see now." ”

Later, I looked it up on the Internet, and Klaus's words were indeed true. And it is true that someone walked 5 steps on top of the flowing magma and recorded a video and uploaded it to the Internet.

To do this, I specifically consulted my fellow geologists who worked in 374. According to him, when the boiling magma meets the cold air, it forms a black crust on the surface for people to stand on, but the time for which a person can stand is very short, because the temperature of the magma is too high, although the magma flows like a stream. But it's actually more viscous than water, which means it resists some small pressures.

As much as I knew I wanted to take Klaus's word, I had no intention of walking up the lava.

The surrounding light was dim, and because of the volcanic ash, everyone's eyesight was not far away. The eye can see things within twenty or thirty yards...... This is still thanks to the strong light flashlight on the mecha, and if you want to see the distance clearly, you can only look at a silhouette in the shadow.

We walked for about half an hour along the place where the vegetation grew in the direction of Professor Yu, and finally found a river next to an underground shrub, because of the lack of light, the shrubs here are not luxuriant, but their root systems are very reachable, and many of them even arch out of the ground and extend into the turbulent underground river.

At this point, we don't have much oxygen left.

Seeing the underground river, Klaus was about to wear a mecha into the water, at this time, Lu Xiaobu grabbed Klaus and asked with a smile: "Lao Ke, everyone's oxygen is running out, should you lead everyone to replenish oxygen?" ”

"What oxygen? You don't have oxygen, and I don't have either, do you want to snatch my oxygen cylinder? Klaus shouted.

Lu Xiaobu laughed cruelly, grabbing Klaus without the slightest intention of letting go.

I was just about to come forward to persuade me, when suddenly Professor Fang next to me grabbed me and signaled me not to worry.

Lu Xiaobu said with a smile: "Since you have already considered that this is a volcanic landform, there is no way to imagine that there will be a situation where oxygen will not be enough, right?" As a military fan, I know that submarines have two oxygen supply devices, the first is to reserve compressed oxygen, and the second is to use sodium peroxide (Na2O2) as an oxygen supply agent in emergency situations! Your mecha is so advanced, don't tell me you don't have this kind of oxygen equipment! Tell us how to use it, and don't wait for us to suffocate a few people. ”

Klaus heard him say all the chemical elements such as sodium peroxide, and knew that there was no point in installing it any longer, so he sighed and said, "You go into the underground river, activate the second breathing mode, and the mecha will automatically replenish oxygen." ”

"Don't move yet, Xiaoliang, you go down to the water and try to see if what he said is true."

I never dreamed that Klaus would still have such a hand, if it weren't for Lu Xiaobu, a military fan, who thought of this stubble, it is estimated that we would have to make a big mistake! So he hurriedly went into the water and tried the method that Klaus had said.

After entering the water, through the voice command of the VR screen, I turned on the second breathing mode, and the compressed air in the compressed air tank on the mecha began to quickly refill.

I asked Lu Xiaobu how he knew about this. Lu Xiaobu proudly showed off: "I have a buddy who designed spacecraft from NASA, and he told me that sodium peroxide is used in mines, tunnels, diving, or spacecraft and other anoxic occasions to convert people's exhaled carbon dioxide into oxygen, an element that can solve ......the oxygen problem as long as there is water that reacts with sodium peroxide." )
