'Frost' laughed, "This won't be!"

Zang Feng asked, "Why not?"

Bing Shuang said: "Think about it, these 30,000 books, each in a different position, has a different order, how many possibilities are there in total? I'm afraid, hundreds of millions of kinds of possibilities are more than that! However, among the different permutations and combinations of these books, placed on the bookshelves on the three rock walls, there are only a few dozen of them, which are the control sequence signals for my Paiqi Men Dunjia. And all the control sequences that turn off Qimen Dunjia are only one. Think about it, among these hundreds of millions of sequences, how easy is it to find which control sequence?"

Zang Feng said: "Yes! I'm afraid I won't be able to find it after looking for a few years!"

Bingshuang said again: "And don't you remember? Once someone, in case they really rush through the moving maze and enter this secret room, the moving rock wall in the moving maze will quickly block the entrance to the maze, cut off the source of oxygen, and no longer let the oxygen in the secret room circulate with the oxygen in the maze." And the oxygen that is locked in the secret room is limited, where can the intruder hold on for a long time!"

Zang Feng heard this, and even said: "Yes, it seems that before the oxygen is exhausted, it is really more difficult to find the book arrangement sequence that closes the Qimen shield armor than to ascend to the sky!"

Bing Shuang said: "Moreover, the intruder, whether intentionally or unintentionally, changed the position of the books indiscriminately, and maybe it will trigger a more powerful mechanism!

Zang Feng asked, "What's going on?"

Bing Shuang said: "Because, among the hundreds of millions of permutations of these 30,000 books on the shelves, only thirty sequences are the overall control signals for Qimen Dunjia! At the same time, among these hundreds of millions of sequences, there are 300,000 kinds of signals, which are the signals that trigger the hidden mechanism in this secret room. Although these 300,000 species, the probability of appearing in these hundreds of millions of sequences is still very small. But if the intruder messes with the books and hits them by mistake, the probability of triggering these 300,000 sequences is still much higher than the probability of triggering those correct control signals of Qimen Dunjia!"

When Zang Feng heard this, he couldn't help but say: "It seems that this organ is also impossible to guard! Because if an intruder enters the secret room, he will inevitably have the desire to go to the stone wall bookshelf to get the book. Perhaps, the intruder, as soon as he picked up the book, triggered the deadly mechanism! Hey, the disciple finally understood now, why did the disciple wait for the frost girl for a long time when he was besieged by many moving rock walls at the Tianyuan coordinate point! It turned out that among the hundreds of millions of book sequences, it was also very, very difficult to find the only book sequence that partially shut down the power of the moving maze. Even knowing the order of the control sequence, arranging these books in the correct order is time-consuming!"

'Frost' smiled: "You can understand, don't blame me, just close the maze too late!"

Zang Feng said: "How dare the disciple blame the frost girl! Because the disciple thinks about it now, after the frost girl entered this labyrinth for the first time, she moved these 30,000 books and turned off the power switch of the outside labyrinth, which was really very fast! If you were a disciple, even if you knew the correct sequence and moved it, I am afraid it would take a day! At that time, it would really cause a catastrophe!"

Bing Shuang said: "The reason why it's fast is actually that there is an easy way! Sometimes, it is enough to fine-tune the position of one or two books! If you really want to make a big adjustment to the sequence of these books, such as now, we still want to call those scarecrows outside." After we gave the order, let those dozens of scarecrows carry them together, so that the speed will naturally be much faster!"

Zang Feng said: "Before, when the Frost Girl entered this secret room for the first time, wouldn't she just call the scarecrows in and let them move the books together, so as to turn off the power switch of the moving labyrinth?"

Frost said: "How is it possible? Just now, when I first entered this secret room, you were still luring many moving rock walls to the Tianyuan coordinates. At that time, the power switch had not yet been turned off. At that time, as soon as I took the opportunity, I jumped over the stone wall that suddenly opened, and the stone wall that sealed the entrance closed again, blocking the entrance! How could those scarecrows come in? Moreover, those scarecrows were also on the other side of the moving labyrinth, cooperating with us to lead away the moving rock wall! Therefore, at that time, in order to turn off the power switch of the moving maze as soon as possible before the many moving rock walls and envelop you at the Tianyuan coordinate point, I had to take the risk and use a simple method to move only a few books, first move the rock wall blocking the entrance to the secret room, and then turn off the power switch!"

Zang Feng said: "I see! In this way, in order to rush into the secret room before, we cooperated with each other, although the disciples were at the Tianyuan coordinate point, luring the moving rock wall, it was dangerous. But compared to the Frost Girl, in this secret room, it is still much easier to race against time!"

Frost said: "Okay! We are now, we have finally succeeded in cooperating! And I want to now, and I have to race against time, don't talk about anything else for the time being." Let's take the magic weapon of controlling the enemy as soon as possible, assist Ling Xu, and go to fight with the seven-colored shadow man!"

Zang Feng heard Frost's words, and at this time, it suddenly occurred to him that the seven-colored shadow man had already come to the 'Medicine Immortal Valley' at this time. At this time, relying on the external Qimen Dunjia alone, I am afraid that it is already invincible. So, he remembered again that after he and Bing Shuang came to the vicinity of the 'Medicine Immortal Valley', they had been delayed for so long in this underground secret passage, and until now, they had not yet obtained the magic weapon to control the enemy, so he asked Xue Shuang with some self-reproach: "We are here, delayed for so long, let Ling Xu's head take the girl in green and meet the enemy alone, you won't blame us at this time, right?"

Bing Shuang said: "As long as we take the magic weapon as soon as possible, and we don't seek to subdue the shadowless evil god, we will only subdue the seven-colored shadow man permanently, even if we don't waste time! Ling Xu's head will definitely not blame us! So, let's hurry up and get the magic weapon to control the enemy!"

When Zang Feng heard this, he said, "Yes, the disciple still doesn't know what the magic weapon of defeating the enemy is?"

Frost said, "Don't guess, come with me!" Frost said this, and Frost walked in the direction of the stone table in the middle of the secret room.

Zang Feng also followed. The two of them approached the stone table. And on this stone table, what attracted Zang Feng's attention the most at this time was naturally the detailed map of the four continents that was tiled. Zang Feng couldn't help but ask in disbelief: "Is it possible that the magic weapon of subduing the seven-colored shadow people is this detailed map of the four continents?"

Bingshuang asked rhetorically, "Don't you see, is there still this wooden box on this stone table?"

In fact, it is also because the detailed map of these four continents is too smart, so it suddenly attracted Zang Feng's attention. At this time, Zang Feng was reminded by the frost, and only then did he notice the inconspicuous wooden box next to him. Zang Feng then asked in surprise, "Could it be that the magic weapon that can subdue the seven-colored shadow man is in this wooden box?"

However, when Zang Feng's hand touched the lid of the box, he suddenly retracted his hand like an electric shock. Seeing this, Frost frowned and asked, "Why didn't you open it?"

Zang Feng said: "The disciple is worried: this box lid is also like a book on the rock wall, it is also a mechanism, if it is opened, it will trigger danger!"

Frost listened and said with a smile: "You're too careful! You don't dare to open it, I'll open it for you!" As she spoke, Frost stretched out her hand and lifted the lid of the box!
