The sweat on Chen's forehead almost merged into a small river, and his eyes were fixed on the light curtain. Before he knew it, he had been in this position for three hours. What a weird pattern! Chen Dui racked his brains to barely make out one structure, and he didn't recognize any of the others. And even the kind of pattern he recognized, he also spent a great deal of effort.

Just as he was figuring out the structural use of this pattern, the pattern on the light curtain darkened at the same time. It was this sudden change that woke Chen Du up from his thoughts.

Looking back at his surroundings in a daze, three hours of long thinking made it a little difficult for him to come back to his senses. It took about half a minute for him to sort it out. Suddenly, I felt wet and greasy, very uncomfortable, and then I realized that I was soaked with sweat unconsciously.

These patterns are all extremely strange, very different from the card system of the Heavenly Federation, that is, the theory in the mysterious card, and there is also a very big difference. However, fortunately, the theoretical knowledge in the mystery card is not completely out of bounds. Chen Dui was able to identify a pattern, thanks to the theoretical system in the mystery card.

It's a very similar pattern to a chipstick, but with a certain degree of difference. In terms of subtlety, it is still slightly inferior to the knowledge of chips mentioned in the mystery card. This allowed Chen Duan to barely recognize a pattern, otherwise, he wouldn't even think about it. These complex structures are a little more difficult for him now.

Twisting his sore neck, he glanced back at Alfonso and saw him staring at the light curtain in front of him with a look of obsessiveness. Alfonso had an extremely complex structural diagram on the light curtain in front of him, and after only a glance at Chen Dui, he had the self-knowledge to retract his gaze, which was too dazzling.

Looking around, Chen Du couldn't help but smile bitterly in his heart, in such a situation, he could still indulge in it for such a long time. No wonder he and Alfonso are together, it turns out that there is not much difference between himself and a madman like Alfonso.

Regaining her composure, Chen Duan began to look at her surroundings.

It was pitch black, with only a square light curtain hanging in midair.

Chen's experience taught him that if he couldn't find the right way, he wouldn't be able to get out of these powerful illusions. But right now, he can't find the right way. This time it was different from the first time he entered the mystery card. After all, the illusion of the mysterious card was released by him, which means that his safety is more guaranteed. But the current vision, although it was also triggered by him, was not the one who released it.

This time is undoubtedly more dangerous.

However, Chen Duan couldn't find any feasible way right now.

At this moment, suddenly the voice suddenly sounded: "The initial determination of permission is over!" ”

A curtain of light suddenly popped up in front of Chen Dui, almost startling him. There were dense numbers written on the light curtain, and Chen Du was dazzled and confused.

However, the voice solved his doubts: "Due to system corruption, the current highest priority event automatically defaults to the recovery system, and the permission score is its contribution to the current best event." Initially, your score is fifteen. It is the highest number of participants in the judging so far. Congratulations, you will have the highest privileges in the system except for the current best event. ”

These words made Chen Du a little confused, and he seemed to understand: "What is the highest authority." ”

"The highest authority is the control of the system. Since you have the highest contribution score, you have the highest control of all the rights without violating the optimal event. ”

This explanation made the confused Chen Du still confused, but he finally heard the words supreme control clearly.

"So I can control you?" Chen Du asked cautiously tentatively.

"I can't." The other party refused very crisply.

Chen Du answered, not disappointed in his heart, if the other party answered yes, he might be shocked.

"Who are you?" Chen asked the simplest question. As long as the other party is willing to communicate, it is already an exciting breakthrough for Chen Du.

"System."

Chen Du chewed this word in his heart several times, but he still felt confused.

"Where is this?" Chen Du continued to ask.

"Down town."

"Downtown?" This strange name caught Chen's attention.

"Yes."

"How are they?" Chen Du thought of his other companions and inevitably asked.

"Except for one who died due to a malfunction, the rest are intact."

The system's answer made Chen Dui's heart tighten: "Who died?" ”

A light curtain immediately popped up in front of Chen Dui, showing Bowen's image on it. Looking at Bowen, who had lost his vitality, Chen Dui had mixed feelings in his heart. Although the presence of Bowen is a threat to him. But in the bottom of his heart, putting aside the grievances between the two, Chen Du is very appreciative of Bowen's ability. He always thought that Bowen was the most powerful of the three of them, both in terms of scheming and personal combat effectiveness, he was the strongest among the three.

Bowen's death, Chen Du did not have much sadness. Appreciation is appreciated, but Bowen is the person he needs to be wary of the most. If there is a chance to kill Bowen, Chen Du estimates that he will make a move. In the same way, if he gives Bowen a chance, Bowen will definitely not have any mercy. The positions of both sides determine each other's attitudes.

"What about the others? What about their scores? ”

The first thing that popped up was Weah's image, and the cold voice of the system said flatly: "He has the highest score, the category of combat members, and the combat score is greater than 65, so it is recommended to conduct a special combat assessment." ”

65 points!

Thinking about his pitiful 15 points, Chen Dui opened his mouth wide and looked sluggish.

'Weah has 65 points, he's the highest. Why am I the highest authority? Chen Duan, who reacted, couldn't help but ask.

"He's the battle score, you're the maintenance score. At that time, the optimal event was the recovery system, so it was judged that your contribution value was greater than his. "The system is very simple.

"Maintenance points?" Chen Dudeng felt a little crying and laughing, it turned out that the system was treating himself as a maintenance master.

Glancing at Alfonso, who was still indulging, Chen Du pointed and asked, "What is his score?" ”

"Nine points." The system cherishes words like gold.

"What about the others?"

The light curtain in front of Chen Dui immediately appeared with the images of everyone, and their scores were listed below. What made Chen Du cry and laugh the most was that Cheng Ying's score item actually read: Logistics! Chen Du really couldn't figure out how the [system] connected a professional card repair to logistics. When I thought of Cheng Ying wearing an apron, holding a huge iron spoon in her right hand, and carrying a bucket of potato stew in her left hand, it was really ...... Except for Weah, no one scored more than 15 points, which also made Chen Du can't help but sigh again about Weah's toughness!

Chen Du understood that if he wanted to get out of the predicament, he needed enough information, so he constantly communicated with the [system]. It didn't take long for him to understand how worthless his so-called "supreme control" was. With so little contribution score, he has very little authority. A little bit of useful information often requires forty or fifty points of contribution points.

Still, Chen Duan was given a lot of useful information.

They are now in an underground base that has a total of seven floors, and right now, only the one closest to the surface has not been completely damaged. In fact, this layer is only 20 percent intact. And what made Chen Du even more speechless was that because the initial determination of authority consumed a lot of energy, the remaining energy of this base would only be able to last until five days later.

No danger! This discovery finally made Chen Duan breathe a sigh of relief. All the information provided by [the system] indicates that they are safe, at least temporarily.

And when Chen Du saw the structural diagram of the first floor, he was shocked.

This underground base is so large!

No wonder it's called Xiacheng, and in Chen's eyes, it's comparable to a small town! Moreover, Chen Duan also found that the first floor had many compartments, about 1,600 rooms, and they were densely arranged like beehives. The space on the first floor is just too big, think about it, the height of the first floor is forty-five meters!

It's hard to imagine that such an advanced and huge underground base is actually a relic left over from a distant to unscrupulous era! It's unbelievable! Chen Du even believed that the best underground base of the Tianyu Federation would not be better than here.

Moreover, almost everything here is made of metal. How much metal ore does this need to be mined? How sophisticated is this metal technology? How much manpower and material resources are needed?

The large number of empty rooms left behind undoubtedly revealed to him that many people had lived in the base. What about those people? Where did it go again? Why did they abandon this base?

For a while, countless mysteries lingered in Chen Dui's heart.

[System] is extremely tight, so far, Chen Du has not received any fundamental information about this base, such as when was this underground base established? And who founded it? Why did such a huge base be built, etc.

But even so, the tip of the iceberg exposed by this underground base has already brought enough shock to Chen Du.

They're out of luck!
