Du Yuqi felt that what Changmei said made a lot of sense, so he and Xi went into the guard room separately and searched patiently. He first chose the guard room on the left. After thinking about it, he came to the handle, then put his hand on the handle, and then carefully observed the situation around him. After all, simulating such a situation was actually the most likely situation that would occur that year. He operated while observing the operating process, so that the fault tolerance rate would be reduced to the lowest.

Then Du Yuqi looked around but didn't find anything special, so he went to see Xi if he had found anything. Xi also shook his head. After Du Yuqi thought about it, he stood in the guard room on the right, and then observed carefully, and immediately found something strange.

It turned out that there was a small window on the wall of the guard room. This small window seemed to be used for ventilation and light. It was not even the size of a person's head. To put it more intuitively, it was similar to the window in a prison cell, with an upright iron bar on it.

This small window looks normal, but it doesn't seem right when you think about it, because where is this place? The laboratory on the second underground floor. This place is at least 20 meters deep into the underground space. Where does the breeze and sunlight come from?

After becoming suspicious, Du Yuqi immediately went around to the left and found that the guard room on the left also had such a small window. However, Du Yuqi was very meticulous and soon discovered the difference between the two. That is, there were six vertical iron bars on the small window of the guard room on the left, while there were eight vertical iron bars on the small window of the guard room on the right.

After discovering this, Du Yuqi immediately became energetic, but this might be a coincidence. But it was actually very simple to prove that it was not a coincidence. Du Yuqi walked forward, reached out for the iron fence, and immediately found that each fence was actually loose and could be taken out easily. Du Yuqi immediately leaned forward to take a closer look and found that the groove for taking out the fence was obviously much smoother than the surrounding area, which meant that someone often took and put down the iron fence.

After discovering this, Du Yuqi immediately revealed a smile, because at this moment he was already 70% to 80% sure in his heart - it was obvious that the secret was hidden in this iron fence!

The two small windows in the guard room are superfluous, and the iron fences erected on the windows are even more inconspicuous. Who would be so bothered as to take and put this thing away frequently?

This can only mean one thing, that is, this small window and the iron fence erected on it are actually very noticeable. Their use should be to prompt the password to open the warehouse door! If Du Yuqi guessed correctly, erecting a few iron fences means pulling down a few times! Their existence can also prevent the person who opens the door from making mistakes in front of the frequently changing password!

After telling Xi about his guess, the two of them stood in the guard room, one on the left and one on the right, and then started pulling the handles very seriously! After pulling the handles in the order of six on the left and eight on the right, there was still no response. Du Yuqi couldn't help but be dumbfounded at this time. He began to think about various accidents in his mind, such as the password was expired, the opening mechanism of the warehouse door was damaged, and his guess was wrong...

At this time, just as Xi was about to come over to comfort Du Yuqi, a series of dense "clacking" sounds came from the depths of the warehouse. It sounded as if a large number of rusty chains were being dragged with difficulty. In my mind, I could even imagine the rust on them falling off non-stop...

Then, the ground was shaking, the chandelier above the head was shaking, and the broken wall was falling from above. It looked like the place was about to collapse. Then, the door opened slowly, and a cold, damp and rotten smell came out from it, which made people feel very uncomfortable.

Seeing this situation, Du Yuqi's heart tightened. As the name suggests, the chip that his group was looking for should be a high-precision thing. It can be seen from the fact that it must be implanted in the brain to be used. The environment in this warehouse is so bad. His group of people worked so hard, but they only found a bunch of broken chips. This is really distressing.

The two waited until the door of the warehouse was completely opened, then walked straight inside. They found that the area inside the warehouse was very large. No wonder they had to lay tracks on the ground to transport the goods. However, this also meant that the two would have to spend a lot of time looking for the chips.

Du Yuqi and Xi had a brief discussion and decided to search separately. After walking about ten meters to the west of the warehouse, Du Yuqi saw the reason why it was so dark and damp. It turned out that there was a big hole on the wall! Water was flowing in continuously from it.

How big was the hole? Du Yuqi didn't even need to lower her head to walk in. However, the water that flowed out was not that big, probably not even enough to wet her shoes. What wafted into her nose was a rotten smell that made her sneeze several times.

This hole didn't look like it was formed naturally, because its shape was quite regular. Du Yuqi even saw a lot of claw marks on the wall of the hole - well, to put it simply, this thing looked like an oversized rat hole...

At this time, Du Yuqi had no intention of exploring the cave, but continued to search for the whereabouts of the chip in the warehouse. At this time, he only hoped that the chip should be a valuable item, and the warehouse manager here was more responsible and kept this thing in a special place. Otherwise, it would be too much work to find a chip the size of a fingernail in an area of ​​several thousand square meters.

The goods piled in this warehouse have been there for more than a hundred years, and the storage environment here is extremely bad, which is very unfriendly to the goods inside. So it is really like a garbage dump at this time, a mess. There is not only moss and other things on the ground, but Du Yuqi even found colorful mushrooms, which look very similar to porcini, but I don’t know what they taste like. It is estimated that eating the mushrooms in this place will make you lose half your life.

After searching for a few minutes, Du Yuqi said that he had given up hope. If the chip was just left in the warehouse, it would have turned into mud. So what he had to do now became simpler. That was to find a small compartment specially used to store confidential and precious things. In this small compartment, there was still some hope that the chip would be preserved.

Because the target was much larger, Du Yuqi found the other sub-warehouse soon - this place was probably not deliberately hidden when it was built, but the focus was on protection. As if to prevent Du Yuqi from finding it, there were obvious warning symbols on it, and permission had to be shown to approach.

Of course Du Yuqi ignored all warnings at this time and walked straight to open the door. He found that this seemingly solid door shook slightly when he pushed it, and then made a decaying sound. Finally, Du Yuqi exerted a little force and found that the door frame was still intact, but the door panel was rotten!

Fortunately, in order to prevent forced destruction, there are two protective doors behind this gate. However, under the dual erosion of time and moisture, these two doors can hardly play a blocking role and were pushed down into the dust by Du Yuqi.

In the end, everything stored inside was exposed to Du Yuqi. The space inside was not big, only 20 to 30 square meters, with five shelves. There were not many things on the shelves, you could see them at a glance, and even fewer were intact. Du Yuqi walked forward and picked up something similar to armor, but before he could exert any force, he heard a slight sound and it turned into debris and dust.

At this time, Du Yuqi could only sigh and look at the cabinet in the warehouse. This cabinet looked similar to a refrigerator, and the door was tightly closed. Du Yuqi tried to pull it and found that it was still closed tightly. This situation immediately made him happy.

At this time, Du Yuqi was too lazy to find any mechanism or way to open it. He simply used the Rift Mind Blade to cut along the gap next to it and pried the cabinet door open directly. There was not even an alarm sound. It was estimated that the alarm device inside had long been broken.
