This time, they finally found some buildings in this world that were obviously habitable, or that could provide people with a sense of protection.
Compared with the previous wasteland, where there is no grass and harsh environment, the conditions here are actually not much better, but they can inexplicably give humans a sense of security.
They discovered a group of residential communities with layers of mounds far away.
The structure of these mound buildings is a bit like the ant dunes on the African savannah.
It is a hill-like building made simply from the clay here and some building materials.
Moreover, these buildings are not fragmented and built independently.
They are flying very closely together, using a huge whole group to show the message that they are hugging each other for warmth.
It's going to be troublesome this time.
Because if you want to know their number and the number of people living there, you need to penetrate into the inner walls of such buildings to inspect them.
As for the group that constructed the building itself, their intelligence level has far exceeded theirs. The group of zombies we just encountered were approximately equivalent to the intelligence level of three to five years old.
Therefore, how to explore without being discovered is the most important thing.
By this time, the mechanical member in the group had withdrawn his obvious robots.
Throwing large things weighing dozens of kilograms is just to give people meat.
At this time, mechanical bees or even smaller things are needed to complete their exploration mission.
But don't be afraid, after this robot summoned several mechanical bee legions, behind each mechanical bee legion he carried a bag of very tiny dust particles that were almost invisible to the naked eye.
"Cutting-edge micro- and nano-monitoring robots."
"It's like slightly larger dust particles."
After saying that, the cyborg controlled his army of mechanical bees and began to fly towards the top of this huge building.
It didn't take long for these high-speed sky troops to arrive at the top of the mound.
And on top of this mound, the bees' favorite eight-figure dance danced comically.
As their bodies shook and they performed various difficult movements, the tiny particles they carried on their bodies were like pollen, falling one after another downwards.
When they fall, they are not like dust or pollen that drifts away to other places as the wind blows aimlessly.
Each of these tiny particles actually has a command center system to control them.
Apart from their tiny size, they are no different from small robot bees.
Therefore, even if the surrounding environment is not good and the air circulation speed is not slow, the dust still falls on the hill-like mound house one after another according to the established track.
After falling to the roofs of these mud houses, they were like small pebbles, spreading downwards.
After encountering an obvious hole like a window or door, they naturally drilled in, and then when they encountered useful information, they opened the real-time feedback graph.
Through the information feedback from these tiny particles, Mai Fan and his party could clearly see the structure of this huge mound house.
There is only one big bulging building outside, but it is like an ant nest, with various passages densely packed.
As far as the part that Mai Fan and others have detected so far, they can't see any specific construction rules.
Moreover, they did not find any living beings or intelligent beings in the surrounding houses.
"We still need to explore further."
As a result, these tiny particles that had fallen on the ground were miraculously suspended.
After monitoring the direction and various flow rates in the channel, they chose a rough direction.
In that area, there is a high probability that there will be the target they are looking for.
Thanks to the large number of dust seeds they brought out, and also thanks to the strong search ability of these dust seeds, after more than half an hour of searching, they finally discovered the life inside this mound building.
Here is a real gathering area of creatures.
Who would have thought that the builders of this nearly 20-meter-high hilly building exposed on the surface of the earth actually lived seven or eight meters deep underground.
Not only that, these zombies living in the depths are continuing construction at this time.
They seemed to feel that the depth was not enough, or that it was not suitable for zombies of their level to live in.
According to their current construction progress, it seems that they want their nest to be developed ten meters or even 20 meters underground.
But the problem is, judging from their original layout, they should have lived normally two or three meters underground.
When these particles floated down, they also passed several abandoned houses, and there were still traces of life in them.
Some traces, even some old furniture and some small odds and ends used in daily life were left behind at the scene with a bit of panic.
What caused this group of high-level zombies to panic?
At this time, the necessary attempts will begin again.
This time, the weapons used to test them were these tiny dust particles.
They are more concealed than this mechanical bee and attack faster, and the needles they carry that can penetrate any skin are made with special technology and are sharper than the tail needle of the mechanical bee.
But at the same time they received the order to attack, the attacked zombies showed what is called the ability of higher-level zombies.
Not only did they react quickly, but they also used their own methods to clean up these tiny dust particles.
Of course, given their size, it would be difficult to capture such a small attacker.
But there are other ways they can clean up such tiny things.
For example, some zombies have developed some special energy attack methods.
They can control the surrounding airflow and squeeze these small things beyond the physical level.
Since the mass of these dust robots is several times higher than that of mechanical bees, the counterattacks of these zombies are basically useless.
Plus there are an extremely large number of these tiny robots.
Even if the attack of one or two is temporarily blocked, the rest can still complete the instructions given by their master.
Then the sharp needles of these tiny robots pricked the zombies' skin.
Together with the basic abilities of the zombies, the corresponding DNA cells, and all the data that can be collected, they are collected into their own storage tanks.
