This is the first time Yi Ting has seen the crystal nucleus layer outside the base, she has always thought that the crystal nucleus of the base is scarce, and it is always in a state of scarcity that cannot be saturated, but she doesn't know that the crystal nucleus layer outside the Feihua base is all wrapped in the crystal nucleus tree.

They walked forward through the gaps in the pipes, and it was very difficult for them to walk, many of the gaps in the pipes were filled with crystal nucleus branches, and at such times, they had to continue to walk forward with another gap.

After changing a few gaps in a row, Yi Ting, who had changed from 4 Yi Ting afterimages and turned back into an entity, asked "Qing Xiran" in front of her,

"What are you looking for?"

"Find an energy pipeline."

The "Qing Xiran" in front of it is not hidden, such a complex pipeline, each of which may be connected to the major lifeblood of the Feihua base, especially such an abundant crystal core layer, when the crystal core is scarce, this crystal core layer can also be used as a reserve energy.

As long as "Qing Xiran" finds the energy transmission pipeline, he can roughly calculate the energy consumption of the Feihua base according to the size of the pipeline, and at the same time obtain an approximate population data.

At the same time, if she can touch the sub-category energy reservoir, she can also get the approximate number of supernatural people in the Feihua base according to the sub-category energy reservoir.

Now there is a saying in the end of the world, the five elements of the ability, also known as the energy provider, this means that the five elements of gold, wood, water, fire and earth, can be converted into direct service to the society of energy, this is the most commonly used five kinds of energy in people's lives, in addition, there are also electric powers, wind powers, can also directly serve the human society.

Qing Xiran has paid attention to it before, many safety areas have set up this kind of sub-category energy storage, the most obvious is the electrical energy storage, because many safety areas, crystal nuclei are not enough at all, so a lot of energy storage will be set up to store various energy, the size of these energy storage and the amount of energy stored in the inside, you can calculate the number of these classified abilities.

For example, the size of the reservoir can calculate the amount of water, and according to the daily consumption, it can also calculate about how many people use water every day, although it is not very accurate, but for the confrontation between the two armies, any detailed understanding of the enemy may be able to play a decisive role at a critical moment.

Yi Ting followed behind "Qing Xiran", she thought that "Qing Xiran" was looking for an energy storage device to cause destruction, so she said:

"It's useless if you find it, the Feihua base is managed separately in sections, and the energy supply system of each section is different, even if you destroy this section, other areas are still running the same."

"Oh?"

"Qing Xiran" turned around with great interest, looked at Yi Ting in the dark, and said:

"Your construction method is advanced, just like the concept of the security zone, in fact, each small security zone is an independent energy supply system, several small security zones, together to form a medium-sized security zone, and then by several medium-sized security zones, to form a large security zone, the purpose of this design is also to prevent one of the security zones from being attacked, which will affect the rest of the area."

Then, "Qing Xiran" looked up at the size and number of pipes around him, and the information that Yi Ting inadvertently provided was very useful, because Qing Xiran could calculate the size, direction, and shape of the entire section of the area through the length and thickness of the pipes.

Knowing the shape of a small section of the underground base, you can roughly infer the distribution of the entire underground base based on the shape of this small section, and then get an accurate overall location of the base on the ground.

It was stationed above, when he was desperately digging a pit on the ground, "Qing Xiran" walked a long, long way along the gap of the pipe underground, and some of the gaps were too small for the human body to pass at all, "Qing Xiran" simply took advantage of Yi Ting's inattention and spit out a small earthworm made of machinery from his mouth.

The little earthworm crawled down the body of "Qing Xiran", and then got into the small gap and went directly to climb the pipe.

It climbed much faster than such a big one as "Qing Xiran", which was specially made by Qing Xiran and placed in Qing Xiaomei's stomach, and was intended to be used by the abacus team.

At that time, she thought that all the surveillance cameras in the mental arithmetic team were broken, so she sent Qing Xiaomei to repair them, and then remotely controlled Qing Xiaomei, swallowing a lot of mechanical earthworms, mechanical centipedes, and mechanical flies...... Don't look at these mechanical bugs so small, in fact, they have sophisticated infrared monitoring, networking, and mapping functions.

Especially mechanical flies, there is also the ability to fly.

It took a few hours to measure the entire length, direction and shape of the entire pipeline in this area.

Sanzhi is in the city, it has entered the middle of the night, because Qing Xiran came here temporarily with a large family, Qu Yang was busy, and he didn't find a suitable house, so he only temporarily arranged them on an ancient street, because it has not been repaired, so this ancient street is not open to other survivors on weekdays.

The people brought over by Qing Xiran stayed here directly, occupying half of the ancient street.

Xu You personally took over the garrison work of the entire Sanguan City, and was holding a meeting with the city commander and camp executive officer of the Sanguan City, Xiao Longbao took the children to throw sandbags on the street, next to the garrison was repairing the street lights, and Wen Jing ran up and down to clean up the room for Qing Xiran.

Because it is an ancient street, the architectural pattern here is a shop in front, a courtyard in the back, and a two-story ancient building.

Qing Xiran was drawing a picture in the shop on the first floor, she only found a random A4 paper at first, and later, asked Wen Jing to find her a bigger paper, and then later, Qing Xiran wrinkled her brows, and stopped drawing on the paper, only took Qing Yiyi's crayons and began to draw on the wall.

The night was already very deep, Wen Jing hugged a quilt, went in from the front room, went to the courtyard, and after cleaning up the bedroom for Qing Xiran, she ran out again, and saw Qing Xiran dragging a chair and standing in front of a wall to draw a ring-shaped thing, she asked strangely:

"What is this?"

Qing Xiran drew very slowly, as if it had taken a long time for her to react, she stood on the chair and turned around, and said to Wen Jing:

"The Feihua base, an unprecedented super-large security zone."
