Under an ancient castle that has been abandoned for nearly two hundred years, there is such a huge underground palace, even the most dull people can feel that the inside story is not simple. If there is no treasure hidden in it, I am afraid that no one will believe it. But correspondingly, if you want to explore treasures, you must go through many dangers and solve one problem after another.

And now in front of the traversers, it is such a labyrinth problem.

If you give up the expedition and return the same way, you will naturally be able to retreat with your whole body. But everyone is looking for treasure this time, so naturally they will not be far away and return empty-handed. In addition, everyone has their own inheritance, and their strength is not weak, so they are naturally bold and bold. With concerted efforts, Longtan Tiger's Den also has the courage to break through.

Therefore, after making sufficient preparations, everyone entered the maze without hesitation.

"Hey, Boss! Is it really okay to go this route? "Shut up, you've asked dozens of times, don't you bother!"

"We've had dozens of dead ends, right?" "Well, almost."

"Qianyu, this is the first time you have made a left turn?" "The third time, one more time you can be sure that the road is going in circles - hey, the right is ahead, it seems that there is hope- hell! Another dead end! ”

"Go back, go back! Go back to the previous intersection! It doesn't work here! "Cut! Why is it a dead end? ”

At this time, in the labyrinth, the traversers gathered together to act. Whenever the distance traveled by the procession exceeded 100 meters, the group would stop for a moment, and then spread out a white cloth on it and write and draw with charcoal strips before continuing on.

For the aborigines of the world of Iber, the labyrinth can be a scary place. But this is not necessarily the case for the traversers. After all, everyone has played puzzle games in the world before the crossing, and walking the maze is one of the most commonly played game items, so they have some experience in solving the maze. Taken aback by the situation they faced at the beginning, the group began to brainstorm ways to solve the maze.

In fact, it is not as difficult as you think to solve the maze.

Generally speaking, mazes can be divided into two categories: single mazes and complex mazes. As the name suggests, a single maze is a maze with only one way to move, while a double maze is a maze with multiple ways to move. The former has a one-size-fits-all solution, which is to walk along a certain wall (i.e., keep touching the wall on one side of the maze with one hand while walking), which may take the longest time, or it may take you to every corner and every dead end of the maze, but you will never be trapped in it forever. And the latter, due to the variety of walks, there must be some places where you can walk back to the origin without looking back, and this passage that can be walked back to the origin shows a closed loop in the maze, with this loop as the boundary, the maze can be divided into several parts. So in this respect, the complex maze can be said to be composed of several single mazes.

The single maze is not difficult to solve, as long as you can afford the time, you can always get out. However, for the complex maze, the solution method of 'walking against the wall' may not be applicable, because the beginning and end of the maze may not be in the same part, and if it is really not in the same part, it is easy to make people go around in circles. And for people trapped in a labyrinth, going around in circles is worse than going into a dead end.

But thankfully, among the traversing teams, Shen Huan's 'Farsightedness' and Han Shan's 'Sentry Guard' can effectively observe the surrounding area. In particular, Shen Huan's 'farsightedness' skill, its observation perspective is similar to the 'Sky Eye Mode', which can clearly observe the surrounding conditions of an area within a radius of 100 meters from its center point, and the geomorphological structure is naturally not a problem. So everyone traveled all the way and drew a map of the maze by the way.

"How long have we been gone?" While resting at a fork in the road, Li Xiang asked.

Yang Qianyu took out a refining sand drain (a prop used for timing in the Yber world) and looked at it. "We've been in the underground for about half a day, and more than seventy percent of that time has been spent exploring the labyrinth."

"The map is pretty much done." Fu Bin spread out the white cloth on the side and pointed. I saw that the white cloth was painted with criss-crossing lines, but there was still a large blank space in the center.

"From the map, we pretty much walked the perimeter of the maze. Many of these roads are interconnected and turnaround, and if it weren't for the 'sentry guards' placed by Han Shan as road signs, I'm afraid we would have lost our way a long time ago." ”

"Yes," Yang Qianyu knocked on the wall against which he was leaning and said, "I don't know what material the four walls of this passage are made of, and even our inheritance weapons can't cut traces, and we can't even make marks." If we hadn't had another means, we would really have to get lost. ”

"It's really suspenseful, but fortunately there is no danger." Li Xiang also nodded. "Let's talk about the road - as shown on the map, we searched all the outer areas, but found no path other than the entrance at the beginning, and this labyrinth is clearly not a dead end. In that case, the final exit is clearly in the center of the maze that we haven't been to before. ”

Yang and Fu also nodded in agreement when they heard this.

"Indeed." Yang Qianyu said: "The wall in the center of the maze does not have any contact with the periphery, and it is obvious that the whole maze is a complex maze - the periphery is a large maze, and the central area is a small maze. The outer labyrinth is stacked by multiple layers of mazes, which are interlocking. If we don't have Shen Huan's cheating skills of 'farsightedness', we won't be able to find the mystery at all if we rush in. ”

"Now we just need to explore the central area and believe we can find a way out." Fu Bin also responded: "Our current position is here-" I saw Fu Bin say as he found out the location of the current team on the map, and then pointed to the center point of the map with a stroke. "The straight-line distance is estimated to be no more than fifty meters, but if you really want to walk, you have to go around seven times, and the actual distance is probably ten times longer."

"Luckily, there are no traps here." Yang Qianyu rejoiced: "Otherwise, it will be more time-consuming and dangerous to finish this journey." ”

"Don't be careless." Fu Bin advised: "There are no traps in the periphery, but not necessarily in the central area. Underestimate the enemy carelessly, and be careful to suffer losses. ”

"Got it, I'm not going to let up." Yang Qianyu knew that Fu Bin's reminder was kind, so he also responded solemnly.

"Alright, tell everyone to rest for another half an hour, and then let's go." Li Xiang decided: "The target is the central area of the labyrinth. ”

"Okay." "Understood."

Dozens of minutes later......

"Roar~~"

"Roar~~"

Crazy and furious roars rang out one after another, like thunder resounding in the labyrinth. The dense labyrinth of alleys caused the roar to echo one after another, constantly transmitting it.

"Zhan Ying, Tianyu. Hurry back! After Yang Qianyu shouted, he waved his hand and sprayed a stream of flames.

Chen Zhanying and Liu Tianyu, who were in front, immediately dodged left and right to make way for the passage. The flames spewed out by Yang Qianyu's 'Flame-breathing Technique' scorched fiercely on the body of a demonic beast that was fighting fiercely with the two.

"Roar!! The demonic beast that burned in flames immediately let out a roar of rage.

"The armor of this ironclad rhinoceros is so hard! It can resist the fire! Liu Tianyu saw that the demonic beast in the flames was just roaring, but it was still struggling, and immediately shouted and reminded.

I saw that the demonic beast a few meters in front of him was more than two meters tall, with a body length of nearly five meters, its huge body was covered with a layer of dark gray armor, and thick and tough tendons were densely covered with that thick body, like a big snake that was entwined. The buffalo-like head had a sharp black horn and a pair of pupils glowing crimson.
