Mecha Star Wars.

Lin Fan looked at the poor little man whose shell had softened in his hand, and stuffed it back into its original position on the box.

"Can you still see it?" Xingchen stretched out his big head, and turned around for a while, pretending that he was an artificial camera, and scanned the place that could be photographed again. "If it's almost the same, I'll close the door."

Theoretically speaking, there is no problem for Xingchen to go down to take a magma bath.

But Lin Fan always looked at the red magma below, and felt a little scared in his heart.

The video images have been collected almost, and it is not interesting to keep the door open.

Xue Ping directly told Lin Fan to close the door and move on.

Once the panoramic camera was broken, only the camera on Lin Fan's headgear was still in use.

While the perspective and automation are not as good as drones, they are better than nothing.

When the danger is eliminated, they can go in and record whatever they like. Naturally, there is nothing to choose under the current conditions.

Lin Fan fumbled all the way, and finally opened a door that wasn't for the outside.

She looked at the slightly dim lights and countless pipes inside, and inserted the instrument for measuring air quality and harmful substances in her hand first.

"Speaking of which, there is one thing that I find a bit strange." During the waiting time, she said to the person on the other side of the headset.

"Tell me." Wu Yusen answered.

Xue Ping was staring at the value on the instrument, and had no time to talk.

"This place has been sealed for a long time, right?" Lin Fan leaned against the door, and put the small box in his hand on the floor inside the door.

This thing is not worth mentioning to Xing Chen, it is still a bit heavy for her to carry.

"According to the geological survey results, the formation time of the surrounding rocks is at least 3000 years." Xue Ping replied, "The environment inside is safe, so go in."

Lin Fan glanced at the value above, picked up the small box, stepped into the room, and asked at the same time. "So how does the air inside come from? Normally, in a confined space that has been dusty for so many years, will the air content be the same as the outside world?"

Don't say she is uneducated.

She has also watched a lot of tomb robbery movies.In many sealed tomb passages, there may not be air.Or just stale poison gas.

Although this place is not a tomb passage, isn't the principle the same?
Even if the house in her hometown has been vacant for a long time, when she went back to get her clothes last time, there was an indescribable smell.

But here...

Lin Fan sniffed vigorously, "I don't know if it's my illusion, but the air inside is a bit fresher than outside."

"It's not an illusion." Xue Ping immediately continued, "From the numerical value, the air quality inside is indeed much better."

Feelings are subjective, but values ​​are scientifically objective.Lin Fan felt right.

The space they are in is more than ten kilometers underground.

Not to mention the heat, although there is a channel to connect to the outside world, but after all the distance is too long and the air quality is not so good.

Coupled with the heat and the large number of people, it really smells a little bit, and it is really not comfortable.

"So, is this reasonable now?" Lin Fan's inexplicable voice came out through the instrument again. "Even if there is an air purification device inside, it can't be turned on all the time... can't it?"

She stopped suddenly, "But then again, there is a response as soon as I touch it... The equipment here seems to be on all the time, but it seems to be in sleep... That is to say..."

"This thing is always on standby." Xue Ping put his arms around his chest and leaned back. "Otherwise, it would be impossible to respond so quickly."

The more complex and precise the instrument, the longer it will take to start up.

Because there are many parts involved, there are system responses and so on.

Anyway, when Lin Fan stepped in and the lights turned on immediately, they discussed this possibility outside.

"Then, to keep running for so many years, shouldn't it require a lot of energy?" Lin Fan continued to walk along the pipeline, and suddenly his eyes lit up.

"Hey! There are stairs." She quickened her pace and trotted over, "It's the stairs going up!"

In inspecting the equipment room and exploring upwards, most people chose upwards.

Lin Fan held on to the escalator and walked up carefully.Xue Ping also took the opportunity to answer questions that he hadn't had time to say just now.

"Supposedly, the energy required for dormancy is not much. But it also depends on the specific situation. You have walked for so long, and you haven't finished the first floor. Calculated proportionally, this is not a little guy."

The more Lin Fan walks, the bigger the 3D map is, and the smaller the new route she walks.

This high-tech unknown space that they thought was the ruins of the ancient city-state was much bigger than they imagined.

While excited, everyone was also filled with emotion.

In a place they didn't know, there was such a high technology long ago, and it has been sleeping underground.

Compared with the scene they saw now, the progress that made them complacent before seemed not worth mentioning at all.

"So, is it possible that the magma is actually a kind of energy?" When Lin Fan was listening to their discussion in the earphones, he somehow had such an idea.

"You mean, in order to maintain its energy requirements, the builders here specially put magma underneath for heating..." Wu Yusen glanced at Xue Ping, feeling that this idea...doesn't seem impossible.

"That's right. Didn't you say that energy conversion is conserved?" Lin Fan explained with his superficial knowledge, "If the magma produces such a large amount of heat energy, if it can be converted into other energy, why can't it be converted into other energy to maintain this big thing?" ?”

Everyone outside looked at each other, and someone immediately ran to the side to start calculating the possibility.

Lin Fan was still talking.

"If the magma was moved here on purpose, then it makes sense why the magma exists in such a shallow place. It has been sealed for so many years, and the energy has not been cut off. Isn't it also reasonable?"

As for how to move the magma...

I'm sorry, that was beyond her knowledge, Lin Fan automatically skipped it.

"You're right, there is indeed such a possibility." Xue Ping boasted, "It's still your brain that provided us with a very good direction!"

Lin Fan's vanity was greatly satisfied, and he finally reached the upper floor with his head held high.

There are many channels of the same kind, many but not chaotic, and they must be praised when OCD comes.

Following the impression just now, I found the location of the door, opened it and went out.

"Look, the air is still qualified." Lin Fan stretched out the instrument again, looked at the value on it and said.

After a few times, she has memorized the normal value.

It's still an empty corridor, which seems to be no different from the lower floor.

But when advancing through the conveyor belt, Lin Fan still felt the change in space.There are also more signs and doors on the walls.

It was just below, but there were doors on one side of the outer wall, and each door was far apart.But now, no matter the left or right, there is a door not far away.

Lin Fan didn't understand the structure of buildings, so she just shook her head as much as she could to make the camera record more comprehensively.

Because she had just stepped into this floor, she was too uncertain, and she didn't dare to open the door rashly like she was on the lower floor just now.

Finally, when the map running progress reached two-thirds of the lower level, Xue Ping gave a new order.

"Lin Fan, push a door and have a look."

The effect of magma is here oh wow kaka wow kaka
