This was the first time Yi Ting saw the crystal nucleus layer outside the base. She always thought that the crystal nucleus of the base was scarce and was always in a state of insaturation. However, she didn't know that the crystal nucleus layer outside the Feihua base was actually wrapped in the crystal nucleus tree.

They walked forward in the gaps in the pipeline, and it was very difficult to walk. Many gaps in the pipeline were filled with crystal core branches. At this time, they could only change one gap and continue walking forward.

After changing several gaps in succession, Yi Ting had changed from 4 afterimages of Yi Ting back to a physical body.

"What are you looking for?"

“Find energy delivery pipelines.”

The "Qing Xiran" in front is not hidden. With such a complex pipeline, each of these may connect to the major lifeline of the Feihua base, especially such a abundant crystal nucleus layer. When the crystal nucleus is scarce, this crystal nucleus layer can also serve as a reserve energy.

As long as "Qing Xiran" finds an energy delivery pipeline, it can roughly calculate the energy consumption of the Feihua base based on the size of the pipeline, and at the same time obtain a rough population data.

And at the same time, if you can touch the classified energy storage, she can also obtain the approximate number of superpowers in the Feihua base based on the classified energy storage.

Now there is a saying in the end of the world that the five elements superpowers are also called energy providers. The meaning of this is that the five elements superpowers of gold, wood, water, fire and earth can be converted into energy that directly serves society. These are the five most commonly used energy in people's lives. In addition, there are also electric and wind superpowers, which can also directly serve human society.

Qing Xiran had noticed that many safety areas have such classified energy storage, and the most obvious one is the electrical energy storage. Because many safety areas and crystal cores are not enough, many energy storage will be set up to store various energy. The size of these energy storage and the amount of energy remaining stored inside can be calculated to calculate the number of these classified superpowers.

For example, the size of the reservoir can calculate the amount of water. Based on the daily consumption, it can also calculate how many people use water every day. Although it is not very accurate, this may have a decisive effect on the battle between the two armies, any detailed understanding of the enemy may have at critical moments.

Yi Ting followed behind "Qing Xiran". She thought "Qing Xiran" was looking for energy storage to cause damage, so she said:

"It's useless if you find it. Feihua Base is managed separately in segments. The energy supply system of each segment is different. Even if you destroy this segment, other areas are still operating the same."

"oh?"

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

"Your construction method is advanced, just like the concept of a safe zone. In fact, each small safety zone is an independent energy supply system, and several small safety zones form a medium safety zone, and then several medium safety zones form a large safety zone. The purpose of this design is to prevent one of the safety zones from being attacked and will affect the rest of the areas."

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

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

It was in the garrison above and while digging a pit on the ground, "Qing Xiran" walked a long and long way along the gaps of the pipeline underground. Some gaps were too small and the human body could not get through. "Qing Xiran" simply took advantage of Yi Ting's inattention and spit out a small mechanical earthworm from his mouth.

The little earthworm climbed down along "Qing Xiran"'s body, then drilled into the tiny gap and went directly to climb the pipe.

It climbed much faster than "Qing Xiran" and each of them was so big. It was specially made by Qing Xiran and placed it in Qing Xiaomei's belly. It was planned to be used by the mental abacus team before.

At that time, she thought that all the surveillance cameras in the mental abacus team were broken, so she sent Qing Xiaomei to repair them, and then remotely controlled Qing Xiaomei, swallowing many mechanical earthworms, mechanical centipedes, and mechanical flies... Although these mechanical insects are so small, they actually have precise infrared monitoring, networking, and surveying and mapping functions.

Especially mechanical flies, they also have flying capabilities.

It was through such a few hours that the entire length, direction and shape of the pipe in this area were clearly measured.

It was already late at night when Qing Xiran brought a family here temporarily. Qu Yang was busy and didn't find a suitable house for Qing Xiran and the others, so they were temporarily arranged on an ancient street. Because it had not been repaired, the ancient street was not open to other survivors on weekdays.

The people brought by Qing Xiran moved directly into the place and occupied half of the ancient street.

Xuyou personally took over the garrison work of the entire Sanbuguan City and was having a meeting with the city commander and camp executive of Sanbuguan City. Xiao Longbao and his children threw sandbags on the street, and next to it was the garrison repairing street lights. Wenjing ran up and down to clean up the room for Qing Xiran.

Because it is an ancient street, the architectural layout here is all about shops in front and yards in the back, and two-story ancient buildings. The shop looks small in front of it, but the inside is quiet and very wide.

Qing Xiran was drawing a picture in the shop on the first floor. At first, she only found a4 paper casually. Later, she asked Wenjing to find her larger piece of paper. Later, Qing Xiran frowned and stopped drawing pictures on the paper. She only took Qing Yiyi's crayons and started drawing on the wall.

It was already deep in the night. Wenjing carried a quilt and went in from the storefront room. When she arrived at the yard, she cleaned up the bedroom for Qing Xiran, and ran out again. Seeing that Qing Xiran dragged a chair and stood in front of a wall and drew a circle-shaped thing, she asked strangely:

"What's this?"

Qing Xiran painted very slowly. She seemed to have been a long time before she realized it. She stood on the chair and turned around and said to Wenjing:
Chapter completed!
