After opening the cabinet door, the first thing he saw was a foul odor coming out of the cabinet, and then a black and sticky liquid flowed out directly from the gap, emitting an indescribable fishy smell, which almost made Du Yuqi dizzy. After a while, he recovered and took a closer look. He found that a large glass bottle inside had been broken, with a label of experimental embryos on it.

However, in another grid, Du Yuqi found a silver box, and the label next to it said "biochip"! At this moment, Du Yuqi was immediately excited, and took it away regardless of the fishy smell inside, and then opened it directly. Because the silver box was sealed very tightly, it was still a bit difficult to open.

However, after opening it, his heart sank, because although the box looked well preserved, there was only a chip left. The crux of the matter was that the chip was broken into two halves, and yellow-brown liquid flowed out from the broken part, staining the white cotton wool underneath with a palm-sized stain.

Witnessing this scene, Du Yuqi was undoubtedly very depressed. Fortunately, Xi's voice suddenly came from outside at this time. After Du Yuqi responded, she quickly appeared at the door.

Du Yuqi looked at Xi and sighed:

"I found the chip, but only one was left, and it was broken."

Xi nodded and said lightly:

"Yeah, I know."

Du Yuqi said:

"It seems this approach is a dead end. We have to think of another way... Wait! What did you say? You know?"

Evening Road:

"Yeah, I know."

Du Yuqi was stunned and said:

"How do you know that?"

Xi Yang raised the notebook in his hand. The notebook was made of kraft paper and looked very sturdy and durable.

"Because I just found a shipment record, which records the shipment status of the latest month, and this biochip was only put into storage within a week. If someone took it away, there must be a record, and the workload won't be too heavy."

"Sure enough, it says here that all the biochips have been taken to the third floor for high-risk implantation experiments. During the inspection, an emergency occurred, causing one of the biochips sent there to be damaged. The damaged one was then returned for damage reporting."

Du Yuqi leaned forward to take a look, and immediately frowned:

"So we have to go to the third floor? But we don't even know where the entrance is!"

The third floor of the underground laboratory has two uses. The first is to test the high-risk experimental subjects that have been prepared, and the second is to destroy the out-of-control experimental subjects. It can be said that the security is extremely strict, and it is also extremely dangerous down there.

However, when Du Yuqi and his team explored before, they had already searched the second floor thoroughly, but still could not find the entrance to the third floor. At this time, Du Yuqi raised this question, and Xi said:

"I have also found the entrance to the third floor, which is inside this warehouse. We previously thought that the track leading into the warehouse was for transporting heavy cargo, but now it seems that it may have this function, but it must be a secondary function. I think the main function should still be to load and transport the prepared experimental subjects on the second floor, and then to the third floor for testing!"

After hearing Xi's words, Du Yuqi's eyes suddenly lit up and said:

"Oh, is that so? Then should we go down to the third floor to have a look? Maybe we can find a biochip there."

Xi nodded and said:

"Well, I came here to tell you this. Something is not right on the third floor. It would be very dangerous if I go down alone."

After hearing what Xi said, Du Yuqi was stunned for a moment and then followed her to the side. This time they went directly along the underground track. After walking about two or three hundred meters, they found that the track actually began to extend straight downwards, and the view in front suddenly opened up. It was a giant deep pit the size of a football field, and the track spiraled down.

That would have been fine, but about ten meters below the giant pit, an extremely thick layer of black fog began to emerge, and it continued to surge, as vast as the ocean, which looked extremely strange.

It is worth mentioning that after coming here, you can say with certainty that the strange buzzing sound is coming from here.

Witnessing this scene, Du Yuqi took a breath and said:

"This...what exactly is going on? The two of us definitely can't go down. Let me think about it. Unless someone like Asura, who doesn't need vision to move freely, can go down to explore, it will be very dangerous for the rest of us to go down."

At this time, Xi said again:

"As soon as we came in, we found that there were no signs of fighting, and there were no corpses. So what happened to cause the lab to be in trouble and be closed urgently? The answer may be found right here. Look at our feet."

Du Yuqi looked down and found that Xi had swept away a layer of dust on the ground, revealing the hard floor underneath. He immediately noticed that the floor was covered with deep scratches, which looked like marks left by sharp claws. Du Yuqi even saw something undulating on the ground next to him out of the corner of his eye, so he scraped away the dust and found that the undulating thing was actually a pile of bones!

Ordinary bones would have decayed long ago in such an environment, but these are metal bones, and they should be modified experimental subjects that were released, so they have been preserved, telling the thrilling stories of the past.

Du Yuqi walked forward a few dozen meters and explored it. He found that the warehouse was incredibly large. The area he had explored before was probably only half of it. In another warehouse, Du Yuqi found a large room with more than a dozen skeletons. These skeletons were all well preserved, and there were no bite marks on the bones. The large room was also very solid. If it had not been for hundreds of years and the humid environment, Du Yuqi really would not have been able to open this door.

So, according to Du Yuqi's speculation, these people should be the staff operating inside. The accident happened suddenly and the warehouse was suddenly closed. They had no time to escape, so they temporarily found such a sturdy room to hide, hoping that someone would come to rescue them.

Unfortunately, although this room seemed to have blocked the invasion of the terrible enemy, the rest of the people were powerless to do anything about what was happening below. It was estimated that their superiors finally issued an order to give up, so they were actually abandoned.

However, Du Yuqi discovered another good news during his search for the corpse. He found a bunch of keys on the corpse. He used these keys to open another secret cabinet inside the sturdy large room. In this cabinet, he found an experimental record.

This experimental record is the relevant experimental information in the third layer of records. Why does it appear here? According to the information revealed in it, it is because among these dead people in front of them there should be a person with a high status, who is the person in charge. This experimental record requires the use of one hundred copies of a precious experimental material called "mature soul essence", and they have prepared for the temporary preservation of the "mature soul essence", so they took it up specially for the leader to review and sign.

This experimental record also mentioned the information that Du Yuqi was concerned about, that is, the biochip.

It turns out that after the biochip is implanted, the subject will fall into a period of weakness and will experience very serious symptoms such as auditory hallucinations, visual hallucinations, aphasia, etc., similar to split personality. The mature soul essence is actually prepared for the subjects implanted with the biochip. Once the side effects during the weak period are too strong, they will be injected with mature soul essence, which can effectively curb the related side effects.

According to the operation procedures obtained here, in order to prevent excessive weakness reaction, ten portions of "mature soul essence" must be prepared before implantation, and implanted immediately when the implantation operation is almost completed. In this way, the prognosis in the later stage will be much better.

At this time, the experimental record for approval is still here, which means one thing, that the mature soul essence needed by the experimental team was not sent out in time. In other words, the biochip used for implantation was only transferred out of the warehouse and placed in the experimental cabinet on the third floor.
