In the large screen, the only yellow area remaining is also rapidly shrinking at a speed visible to the naked eye under continuous erosion and decomposition.

The size is getting smaller and smaller, just as everyone thought that the warship might have completed the dismantling smoothly and quietly.

Who knew that things had changed completely.

A few minutes later, most of the original tetrahedral warships had disappeared at this time. At this time, only a yellow spherical shape appeared quietly near the center of mass of the tetrahedral warship.

The erosion and decomposition fell to a standstill, and the picture seemed to fall into static, and it was maintained in its original state and no longer changed.

"No breakthrough can be found!"

"Invasive attack failed!"

...

A series of failed information is fed back.

Seeing this, everyone felt a little disappointed without making a single move, but they breathed a sigh of relief.

"This is normal. I thought I would succeed in everything in one go. If that were the case, I would doubt whether there would be any other unknown problems here." Zhao Ronghao breathed a sigh of relief, and at the same time he laughed.

"Yes, but I'm still curious why they didn't turn on the self-destruct mechanism?" someone said.

"From the current spherical shape has invaded and decomposed, it should be the location of the core hub of the control center." Wen Ziqiang looked at Cheng Xiang and then guessed.

"It should be true." Cheng Xiang nodded while looking at the large screen information, "However, I'm afraid this control center will be more difficult to get in."

"We have to rely on strong attacks to detect spores that can block the information of the third generation of Type A. In a short period of time, it is basically impossible." Cheng Xiang just finished speaking.

New detection data has been passed.

Everyone's face turned dark when they saw it.

"Strong force material?"

"All this big movie?"

"How is this possible?" everyone exclaimed.

Cheng Xiang's eyes flashed with such a face.

Without waiting for everyone to be surprised, more information was passed on.

Compared with previous contour information, today's graphic information is much richer.

This is a smooth sphere. There are eight small pieces of specially divided spheres on the surface of the sphere. It looks like a hatch door. Above the hatch door, a fine color array like a mosaic is flashing and changing rapidly.

The flickering is very regular.

Everyone wanted to see something from these pictures, but they were helpless and could not understand anything except looking at the glasses.

A few minutes later, Cheng Xiang stopped observing.

"Chief Cheng, have you seen something." Wen Ziqiang asked hurriedly.

When Cheng Xiang heard Wen Ziqiang's question, he couldn't help but smile, and then nodded slightly, "See it, but this may be a very troublesome problem."

"Very trouble?" Wen Ziqiang had a question on his face, and at the same time there was a hint of surprise in his eyes. Cheng Xiang could tell the troublesome problem. It can be seen that such a problem is definitely very difficult for ordinary people.

"Yes, it's very troublesome." Cheng Xiang nodded and confirmed, "You can see that according to the statistical results of the supercomputer, these eight flashing positions are played repeatedly with 9 identical images as a loop."

"The first 8 images are all composed of small pieces of pixels of various colors, and each image has 9,527 small rectangular dots of various colors."

"And on the last picture is a picture composed of small solid-color rectangles."

"According to my guess, everyone thinks, is this like a password gate?"

"The first 8 images are the questions, and the last solid color image is the answer sheet we need to fill in the answer."

"When the answer is correct, the door will open..." After Cheng Xiang's analysis, everyone came to their senses and followed Cheng Xiang's thoughts. It was really possible, and the possibility was very high.

Aliens may not call this thing, but the concept of door is not a rare thing for smart civilization.

"Since it's a password gate, then, I want to ask, can we keep trying and making mistakes?" Zhao Ronghao seized the key point and asked this question. Everyone immediately realized the importance of this question and paid attention to it.

Although brute force cracking is a bit stupid, it is also a simple solution to the problem.

Cheng Xiang looked over and said, "I haven't tried this, so I don't know and can't draw conclusions. However, even if it is possible, brute force cracking is not feasible or undesirable."

Cheng Xiang took a look at the flashing picture again.

"Why?"

"Our current supercomputing speed is twelve orders of magnitude higher than before!" Zhao Ronghao was very puzzled, "If we could crack it brute forcefully, can't we do anything like this simple door?"

Cheng Xiang laughed after hearing this, "Our supercomputing speed is indeed fast enough and has very powerful computing power, but we may not be able to do anything to talk about the password gate in front of us."

"I don't say whether our supercomputer can connect to this door."

"Even if the speed of our password input can be synchronized with our computing power calculation speed, it is unrealistic to crack brute force." After Cheng Xiang said this, Zhao Ronghao and his group were confused.

Why is this unrealistic? It’s obviously very simple. There are less than ten thousand dots on this image, so how can it be difficult?

Looking at everyone's questions, Cheng Xiang did not keep it a secret and continued: "Everyone knows the latest progress of the octopus hypothesis."

Wen Ziqiang nodded, "Chief Cheng, are you talking about the octopus language breakthrough discovered by the genius biological scientist Shen Luoyun a few months ago?"

Cheng Xiang nodded, "This is what I want to say."

"In the octopus hypothesis, the latest progress of text cracking, the number of frequency categories of a single pixel has reached more than 600, and this is not the upper limit, and the final result will continue to rise."

"But does this have anything to do with what is happening now?" Zhao Ronghao continued to ask with dissatisfaction.

"The problem is big, and it's getting bigger." At this time, an auxiliary scientific consultant sighed from the side. He understood it, and his voice immediately attracted everyone's attention. Looking at everyone's doubtful eyes, the scientific consultant continued: "Now, assuming that the possibility of a single block is 500, then, there are 9527 blocks at present, and the possibility here is 500 to the power of 9527."

"With such a huge number, even if the speed of our input answers is the same as the speed of our supercomputer's computing power, we cannot use the exhaustive method to crack such a door. It is an unimaginable huge number." The scientific consultant still had a shock after speaking.

"It's indeed a very unimaginable number."

"Ten thousand orders of zero, even if our supercomputers are spread throughout the Milky Way, they may not be able to brute-force the door to crack such a door." Cheng Xiang sighed.

When everyone heard Cheng Xiang’s vivid statement, they were even more shocked.
