——

The aura around him shone brightly, and Liang Feng's head was dizzy and seemed to wake up immediately. In an instant, a four-layer spiritual power shield 'Tianzun Vajra Talisman' was activated, and his gaze swept forward-

"It's weird! It's weird! Why do you keep going in circles?" muttered as he stood in the middle of the stone chamber and looked around.

The stone chamber he is in now is the stone chamber of the palace in the center of the fourth floor of the underground palace. When he first teleported from the palace hall to this stone chamber, he killed a rather powerful Yaksha here, and obtained a Yuan Soul Bead twice the size of a pigeon's egg and an eleventh level Soul Refining Stone, and he was still quite happy at that time. But now when he returned to this stone chamber, he couldn't be happier—he had teleported to this stone chamber for the eighth time through the teleportation array.

He didn't need to look now to know that outside the A stone room was the only and not long corridor, and there were two other B and C stone rooms on the corridor, and there were only those two rooms.

There was a floor tile teleportation array in the two stone chambers B and C, but he tried the two floor tile teleportation arrays four times, and the results were all the same—the teleportation array in the B stone chamber was teleported to another D stone chamber with stone walls on all sides and no door—in this D stone room, he got a blue-grade 'Xuanyin Lingzhi'. Fortunately, this closed D stone room also has a floor tile teleportation array, but after he passed the teleportation of the teleportation array, he returned to the A stone room where he started.

The teleportation array of the C stone chamber is even simpler, not teleported to a certain X stone chamber in the middle, but directly teleported back to the A stone chamber.

After searching for a while in the empty stone room, of course, he still didn't find any hidden teleportation arrays and mechanisms, Liang Feng was helpless, and took out the map again and began to check - this map was given by the Immortal Water Grandmaster Yanyan, saying that it was the map of the fourth-layer underground palace palace, but he had looked at it several times before and didn't understand how this map was used.

The densely numbered red lines on the map intersect with the blue line - Liang Feng looked at it for a long time, and suddenly had a flash of inspiration in his heart: "The meaning of this red line is from B to D to A, and the meaning of the blue line is from C to A, which is similar to my current situation?!"

“...... The red and blue lines are numbered together, why?...... The red line 1234 means that you have to repeat the route from B to D to A four times, and the blue line 5 and 6 means that you have to repeat the route from C to A for the fifth and sixth trips, and then take the route of the red line 7 and 8, so that the green line from C on the ninth line means that you have jumped out of the loop!"

"Malegobi, how did this labyrinth circle jump out of the dead loop like this?" A thought flashed in his heart, and Liang Feng immediately headed towards the B stone chamber outside the corridor——

Two hours later, Liang Feng, who was still back in the A stone room, sighed and sat down on the stone wall to rest—just now he tried back and forth dozens of times according to the method shown on the map, but he still didn't get out of this dead loop!

"Malegobi, this approach should be the right one. I haven't jumped out of the loop yet, so I think there is a problem with the number of lines on this map...... However, after trying several times that he thought were possible, it was still not right, so what should I do now?" he thought to himself.

He knew that there was no way to use the exhaustive method in this case—although there were only two options for route A and B, he didn't know how many times he had to repeat route A and route B to get out of the loop, and even if he knew, he wouldn't be able to try them all if it was a lot of times—

If the A and B routes are repeated ten times combined, then the first teleportation has two options, A and B, and the second time is the same. Pushing on like this, the whole combination of the general route is 2 to the 10th power, a total of 1,000 and 24 - if he tried the past method one by one, he would have tried fifty routes in a day, and if he was unlucky, he would not have been able to enter the center of the palace for the remaining ten days.

Now, Liang Feng still wanted to try as hard as possible to enter the central palace - one of the things he felt was okay with his safety in this fourth-layer palace -

Although here, the ghosts of the gang such as Black and White Impermanence, Yaksha, and Bull Head and Horse Face are very powerful, but he has a defensive array, a trapped formation, a very powerful spirit rune, and a sonic attack plus 'Divine Night Thunderbolt' and 'True Yuan Divine Thunder', and finally his 'Netherworld Divine Sword' currently has ninety percent divine sense, and he has not used it yet. Therefore, although it is a bit difficult to kill a group of ghosts at the same time, it doesn't seem to be too difficult to kill one by one now, for example, not long ago, he was in the entrance hall of this palace, and he completely destroyed the two black and white impermanence that he met on the first floor and fled, who swore revenge.

Second, if you enter the central palace, you can not only kill more ghosts and do your best to protect the Great Circle, but also get many valuable treasures. He can probably only come to the dungeon of Fallen Demon Island once in his life, and it may be difficult to have a similar opportunity in the future after missing such a good opportunity to accumulate a lot of wealth-

In this fourth-layer underground palace, especially in the several stone chambers of the palace, he obtained a lot of valuable treasures, such as five sixth-level 'Yuan Soul Beads' of different sizes, three twelfth-level soul refining stones, one eleventh-level essence stone, three blue-grade high-grade 'Xuanyin Lingzhi', and more treasures of slightly lower value.

After resting for more than half an hour, Liang Feng took out the map and checked it in his hand - for a long time, he didn't move, like a stone sculpture.

Although his body did not move, the thoughts in his mind never stopped, and he kept putting forward ideas and kept denying them, and he didn't see or come up with any new solutions.

Looking at the one-word title at the top of the crude and old map, he muttered, "What does the title mean by only one 'eight' left?...... Eight...... Eight ......"

Seeing that the red and blue lines on the map were all eight or sixteen in a cluster, Liang Feng had a flash of inspiration in his mind, and said secretly: "Malegobi, this 'eight' character should be the first word of 'Bagua XX Maze', because the time is long and poorly preserved, the words behind it have faded." ”

“...... Is that 'gossip maze'?"

There are a lot of magic circles at the beginning of 'Bagua', such as 'Bagua is not moving like a mountain defensive array', 'Bagua Xuanji Trapped Array', 'Bagua Streamer Sword Array', etc.-Liang Feng has dabbled in these magic circles, but because there is no complete cheats and the effect of these magic circles is not as good as the 'Reverse Five Elements Array', he did not study it in depth.

After looking up and thinking for a moment, Liang Feng took out a large handful of jade slips and began to check them - these jade slips were all newly snatched in the dungeon, such as those snatched from Yan Chaozhuo, Shi Qiangwei, and Zhen Quancan of the Holy Fire Sect, such as those snatched from the Immortal Water Sect's Hua Zhongdie, and for example, from the bodies of several zombies when he was on the third floor of the dungeon—he remembered that among the jade slips he got were several pieces of jade slips of the magic circle cheats, and one of them was still ' 'Gossip XX Array', but he just skimmed it quickly before, and he wasn't so impressed.

After checking it for a long time, Liang Feng took a piece of jade slip and put it on his forehead to read, and said secretly: "Yes, it's this piece of 'Bagua Star Hanging Maze'!" This piece of jade slip he got from Gu Dahong, the deacon of the Houtu Sect who set up the 'Peach Forest Qingxi Phantom Array' to attack him.

After carefully reading the 'Bagua Star Hanging Maze' jade slip twice, he muttered to himself: "It's strange, this 'Bagua Star Hanging Maze' cheats don't seem to be complete, only seven trigrams, missing the leading 'Qiangua', why?......"

After thinking for a moment, he said secretly: "Yes, this is for secrecy! The magic circle diagram of the 'Qiangua' part should be dictated, so that others will not be able to learn this magic circle even if they grab this 'Bagua Star Hanging Maze Array' jade jian." ”

After flipping through the jade slip and reading it several times, Liang Feng's heart moved again: "This jade slip is very new, it has been made in recent decades, and the jade is usually numbered, indicating that it was made in batches......"

“...... This time, the Great Circle of Fallen Demon Island needs a minor repair, so does it also need to be repaired inside the dungeon?...... This Fallen Demon Island Great Circle is so huge, if it needs to be repaired, there is no reason why the inside of the dungeon should not be repaired!"

“...... If repairs are needed inside the dungeon, those deacons of the Later Earth Sect are the right people - they are the most proficient in the circle. If these deacons have maintenance tasks on them, they obviously need to have a certain understanding of this dungeon circle, including the route to enter the fifth layer of the dungeon!" "If the deacons who are carrying out maintenance are trapped by this fourth layer maze and can't reach the fifth layer, then how can they repair it?"

“...... Well, the maze here is mainly to prevent the Netherworld ghosts that have been teleported to the upper level from returning to the fifth layer. "If there is no maze in this maze, then the ghosts, zombies, insects, etc. that have surged from the Netherworld and have been teleported to the upper layers may return to the fifth layer of the dungeon, in that case, the attack on the fifth layer of the dungeon may be much more serious, and the time for which it can remain stable will be drastically reduced.

“...... If you design the Great Magic Circle of Fallen Demon Island yourself, you will also set up a powerful maze here. He thought to himself.

In order to prevent the ghosts from returning to the fifth layer, and possibly more importantly, to prevent some monk scum from entering the fifth layer to cause damage, and there is also a need to leave an entrance to enter the underground palace for maintenance, it is necessary and probably the only way to set up a powerful maze here.

“...... This 'Bagua Star Hanging Maze' Jade Jane deliberately omits the 'Qiangua', obviously to prevent people with bad intentions from learning this maze after getting this Jade Jane. ”

“...... From this point of view, the maze of this fourth-layer dungeon is very likely to be this 'Bagua Star Hanging Maze'!" he made a judgment-

Why does that deacon of the Houtuzong have this maze of jade slips? Why is this jade slip so new? Why is there still a hexagram missing from the jade slip cheats?—— if this dungeon maze is a 'Bagua Star Hanging Maze', then all these questions can be reasonably explained-

The deacon has the task of entering the fifth layer of the dungeon for maintenance, so he has a maze jade slip on his body; the jade slip is so new because a batch was made out decades ago to train a group of deacons, so that he can take on the task of repairing the dungeon now; the reason why the jade slip cheats should be kept secret is that this maze is really a big responsibility, and it can't be leaked out and obtained by the scum of the monk with ill intentions.

"Although this magic circle cheat book is incomplete, it is still useful!" Liang Feng quickly browsed the contents of the magic circle jade slip in full, excited in his heart.

Of course, he couldn't work backwards from the other hexagrams to deduce the diagram of the 'Qiangua' - this diagram was very difficult and computationally intensive, similar to the top crown of the mathematical branch of cryptography in his previous life memory - the encryption algorithm was known and had an infinite number of ciphertext strings, and then the encryption key was calculated backwards - which was usually impossible before the advent of supercomputers, unless the encryption algorithm itself was flawed.

However, although he can't reverse the formation diagram of the 'Qiangua', he knows that as long as he learns the formation diagram of the other hexagrams, he can deduce and calculate part of the line situation-

For example, if you want to jump out of the loop here, you need to take a total of 16 routes A and B, and if you try them one by one, the route might be BBBB...... BB or BBBB...... BA or BBBB...... AB or BBBB...... AA and so on, the total combination of these lines is as much as 2 to the 16th power. Obviously, it can take years or decades to try them all one by one.

Now that he has the formation of other hexagrams, of course, he still can't deduce an accurate route, but he may be able to deduce, for example, how the first twelve or the last twelve times should be taken, for example, the first twelve times should be AAAAAABBBBBBBB, then the remaining four routes that cannot be calculated need to be tried one by one- In this way, although it is still necessary to try some routes, this is equivalent to a power reduction, and the number of attempts has been drastically reduced, and it may only take an hour or two in total to try all the possibilities.
