"Okay, then it's decided. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info," Zhou Xin said.

So, Zhou Xin left some of the probes in this hall to do the finishing work, and then ordered most of the probes to move towards the new passage.

The passage was about 15 meters long, and there was still a large door at the end of the passage, and when the gate was opened, a new hall appeared in front of Zhou Xin and them. This hall is obviously not as big as the previous hall, the diameter is only about 50 meters, compared with the previous hall, this hall is not separated by low walls, the whole is very empty, Zhou Xin and they can see the situation in the hall at a glance. The floor of the hall is covered with white lines that divide the floor into different shapes, some are circular, some are rectangular, and some of the divided areas contain some instruments. And there are small doors on the walls around this hall every two or three meters, and these small doors surround the entire hall.

Seeing the situation in the hall, Zhou Xin suddenly remembered the small hall he had seen at the beginning, and he said: "Look at the situation here, this place should still be a living area, are we going to get nothing again?" ”

Spred nodded, "It's really similar to the small hall at the beginning, let's investigate first, maybe there's something new." ”

"Hmm." Zhou Xin nodded, "Then let's get started." ”

Zhou Xin ordered the probes to disperse and explore, and they began to observe the hall from the perspective of one of the probes.

The detector seemed to be assigned to a far away room, as Zhou Xin and the others saw that the detector was heading straight for a door on the opposite wall after exiting the passage. While the probe was advancing, Zhou Xin looked at the areas of different shapes on the ground and said, "The place on the ground surrounded by white lines should be this civilized way of entertainment, and there are several that seem to be quite similar to our sports field." As he said this, Zhou Xin saw a rectangular area with a net placed in the middle of this area.

"There are also some venues that are very similar to the way we entertain." Spred said, looking at a circular field.

The probe continued to move forward, and after a while, it moved to one of the doors, and when it opened, the familiar furnishings appeared in front of Zhou Xin and them again.

The furnishings of this room are almost exactly the same as those in the rooms around the small hall at the beginning, Zhou Xin and the others subconsciously looked in the direction of the bookshelf after seeing these furnishings, and sure enough, there were still no books on the shelves, only a few decorations still played their original duties on the shelves. Seeing the empty bookshelves, Zhou Xin and them were very disappointed, Zhou Xin sighed slightly, and then looked at the bed on the other side, but to their little relief, this bed was a little messy, obviously with traces of life.

Zhou Xin breathed a sigh of relief, he motioned for the probe to continue the investigation, and then said to Spred, "Now it can be determined that this base once had life." ”

"Well, at least one doubt has been solved." Spred nodded, and then he asked, "But why have we been here for so long, and we haven't seen a single truly civilized creature?" ”

"Maybe they have some reason." Zhou Xin guessed.

"I hope so." With that, Spred sighed.

Over the next half day, the probe investigated the hall and the small rooms surrounding the hall in detail, and found that this area was indeed the living quarters, as previously inferred. After searching all the rooms, the probe still did not find any information in the room, but it was reassuring to note that most of the rooms in this living area showed traces of life, and even a small number of household items were found in several of them. In this way, the probe completed the exploration of this part of the area.

So, after briefly summarizing the situation of this hall, Zhou Xin ordered the probe to go to another passage on the left, which was only about 15 meters, and after opening the door at the end of the passage, a high wall appeared on the screen.

Unlike the previous low walls, this one extends straight up to the ceiling, and the probe cannot fly up to observe the entire hall. Zhou Xin took a slight look at the surrounding situation and found that there was a walkway left on the left and right sides of the wall, Zhou Xin asked the detector soldiers to divide into two ways and explore the two walkways at the same time, while he chose to explore the lens of the detector in the left walkway.

The detector moved along the arc-shaped walkway, and in the process of advancing, Zhou Xin saw that a display screen appeared on the wall on the inside from time to time, or some strangely shaped devices, and several transparent windows similar to observation windows, looking inside through the windows, Zhou Xin saw a huge thing standing in the middle of the hall, but the observation window was covered with dust because it had not been used for a long time, so Zhou Xin and they couldn't see what was inside.

After advancing more than thirty meters, the probe came to an alloy gate, which the probe tried to open, but found it locked. On the wall on the side of the gate, there is a display screen, and there are several rows of buttons under the display, and a string of text is displayed on the display, and there is a string of spaces under the text.

"Looks like our good fortune has come to an end." Zhou Xin sighed slightly, he looked at the display screen in the lens, "This should be the password door, one, two, three...... Twenty, twenty digits, we should go there and find the password. ”

"Look at the digits of this password, this should be a very important place." Spred said.

Zhou Xin nodded, "It looks like this door can't be opened for the time being, let's take a look at the situation on the other side." ”

So, Zhou Xin motioned for the detector to try to crack the code on the door, and then turned the camera to another set of detectors.

The probes continued to move forward, but after a while, the probes also encountered an alloy door. There is also a cipher device next to the alloy door. Seeing this password device, Zhou Xin was suddenly helpless.

"Looks like it's not going to work here." Zhou Xin said.

"There's still some way to explore in it, so let's take a look." Spred reminded.

Zhou Xin nodded, and ordered one of the probes to continue to explore, walking about fifty meters, this probe saw the previous group of probes, and now they are still analyzing in front of the first cipher door.

"It looks like there are only two doors here, and if you want to get in, you can only find the password." Zhou Xin sighed.

"Hmm." Spred nodded, "Since this hall can't be explored for the time being, let's go explore other places first." ”

So, Zhou Xin left several detectors in front of each of the two doors for analysis, and then ordered the remaining detectors to enter another passage on the left to continue exploring.

The length of this passage was obviously much longer than the previous passage, and after advancing about thirty meters, the probe reached the gate at the end of the passage, and when the gate was opened, the scene in front of them made Zhou Xin and them a little surprised.

The hall was very large, about the same size as the previous hall where the statues were placed, but unlike the previous hall, this hall was vaulted and not separated by low walls. However, in the middle of this vaulted hall, there is a huge transparent hemispherical wall, which occupies almost the entire space of the hall, and is only about a meter away from the wall of the real hall. Looking into the transparent wall, Zhou Xin and the others clearly saw that the circular space inside was divided into four equal sectors, and there was a stream of water between the fans, and at the same time, this flow of water also surrounded the entire hall along the transparent wall.

The probe moved along the aisle between the two walls, and after a few steps forward, the probe found the door to enter, to Zhou Xin's relief, the door did not have a password, and the probe opened the door with a slight push.

Entering the interior of the glass wall, the scene seen outside clearly appeared in front of them, Zhou Xin and they saw that some plants were neatly planted in the four areas that were divided, because the distance was too far, what were planted in the two pieces in the distance Zhou Xin They couldn't see clearly, but they could see the plants planted in the two areas at close range.

One of them was planted with a plant similar to that of rice, but the whole plant was obviously much larger than rice, almost twice the size, while the other area was planted with a plant that Zhou Xin and they didn't know at all, this plant was about the same size as the rice next to it, but there was a total of apple-sized fruit growing on the hard stem, and this new plant slightly aroused Zhou Xin's interest.

"Looks like this is the source of food for this underground base." Looking at that strange plant, Zhou Xin said, "This plant is the first time I've seen it, and it's also one of the foods of this civilization?" ”

"It looks delicious." Ralph drooled on the side, "Uncle Captain, get some and try it." ”

"Nope." Spred stopped, "Who knows if we can eat the food that suits them, Ralph you know how to eat it." ”

However, Zhou Xin quite agreed with Ralph, "Let the detector test the ingredients of these foods, if they are not poisonous, we can still taste them." ”

Ralph immediately became happy, "Uncle Captain, you need to hurry, I can't wait to try it." ”

"Okay, okay, I won't miss your share." Zhou Xin comforted, and then he motioned to leave a few detectors for detection, and the rest headed towards the other two areas.

When they arrived at the other two areas, Zhou Xin and the others saw that one of the areas was planted with plants similar to fruit trees, but these "fruit trees" were a little low, and the tallest was not more than four meters, and some of them still had fruits on them. These fruits can be roughly divided into three types: one is a fist-sized red spherical fruit; One is a green olive-shaped fruit the size of a head; The remaining one is a pigeon's egg-sized cluster of bright yellow fruits. In the other area, there were low vegetable crops, but Zhou Xin didn't recognize what they were. Seeing that there was nothing else, Zhou Xin handed over all the investigation and testing work to the detector, and then ended the day's work.

The next day, the probe gave detailed findings, and with the exception of the bright yellow fruit the size of a pigeon's egg, which has a hallucinogenic effect, all other plants are actually available for human consumption. In this way, the probe completed the exploration of this area, and Zhou Xin and the others harvested several edible plants.

So, after instructing the robot to transport some back, Zhou Xin and the others headed towards a new channel.

The passage is only about ten meters, but the gate at the end of the passage is locked, but fortunately, the switch to open the door is not hidden, but next to the door.

It was an ordinary display, and there were eight ovals of different sizes, one of which were set on top of each other, and in the middle of the smallest oval there was a ball of light, and below this pattern, there were eight spherical objects of different sizes, and below the spherical objects there were three square spaces, and there was nothing in the spaces.

"What does this password mean?" Seeing the strange pattern, Spred asked.

"I don't know." Zhou Xin said, he motioned to the detector to operate the display, after the detector operation, Zhou Xin and they found that the pattern above is fixed, but the spherical objects arranged below can be moved, at first, Zhou Xin asked the detector to move those spherical objects to the bottom box, and found that it failed, just when Zhou Xin was puzzled. The detector inadvertently moved a spherical object to the elliptical lines, and the spherical object actually moved along the elliptical lines.

Seeing this scene, Zhou Xin and the others reacted immediately, and Ralph said lightly on the side: "Isn't this just arranging passwords, just put the balls on the oval in order, but it's just a different look." And there are only eight digits, so it's simple. ”

Seeing that the password was only eight digits, Zhou Xin and they were also surprised at first, after the surprise, Zhou Xin felt that this pattern was a little familiar, but he couldn't remember where he had seen this pattern, just when Zhou Xin was thinking about where he had seen this pattern, the detector had already placed the spherical object on the oval in order from large to small, at this time, Zhou Xin and they heard a warning sound. After the warning sounded, Zhou Xin saw a blank grid at the bottom of the display turn red. Zhou Xin hurriedly stopped the probe's next move.

Looking at the remaining two blank boxes, Zhou Xin understood, "Are there only three chances in total?" It's a bit tricky. ”

"Ahh This civilization is cunning. "There are only two chances left, where are we going to find the password?" ”

Zhou Xin didn't answer Ralph's words, he looked at the picture in front of him, fell into deep thought, and after thinking for a while, he found that there was really a picture in his mind that was very similar to the picture in front of him, but he couldn't believe his judgment.

He said to himself, "Is it really this picture...... ”
