According to the introduction of Shiku when he first arrived, as well as the supplementary explanation on the thirty-seventh day after that, Shi Leiyin already had a general idea of the situation in the Labyrinth Secret Realm. ＠，

The secret realm itself is in a very powerful barrier, with an area of about 10,000 square kilometers, equivalent to the size of a giant city.

The secret realm enchantment has a very high-level hidden effect, but because of the eldest lady of the dragon clan, the existence of the enchantment is still discovered by human adventurers on the continent. So, in order to prevent the adventurers from using other means to forcibly break through the barrier. Ku had to create an entrance to weaken the adventurer's idea of forcing a breakthrough, and set up a defensive labyrinth to block the adventurer's invasion.

Due to the hundreds of years of operation of the Jinkisi Chamber of Commerce, the mainland has a near-common sense habit of invading the secret realm by using the guò labyrinth, so when the entrance to the secret realm maze is opened, all adventurers give up other means to enter the maze, and in their common sense, those means are far less reliable than the guò maze.

The size of the Uncharted Labyrinth depends on the size of the passage when it was originally created. When the library built the labyrinth, it took into account the necessity of expansion, and directly built a large vertical passage large enough to put down the nine-story labyrinth. After that, start building the maze on each floor. However, due to the pressure of time, the library finally had to open the entrance to the maze ahead of schedule after only completing the first two floors.

The Mystery Labyrinth is located directly below the Mystery, and is slightly smaller in size than the Mystery, so it can be protected by both the ground and the Mystery. It will not be damaged by some force majeure.

However, this setting leads to zhì, to enter the labyrinth, you must first descend from the cave at the entrance to the lowest level of the labyrinth, and then go up to the secret realm labyrinth layer by layer, and finally arrive at the garrison town where mercenaries like Shi Leiyin live, and then you can be regarded as officially entering the secret realm.

The labyrinth that has been built is the first and second floors at the bottom, and in addition to the dizzying maze paths, there are also a lot of traps. And the mercenaries who came to the secret realm earlier have also entered it, either stationed in key passages, or wandering in a certain area, and some are guarding low-level treasures deliberately placed in the labyrinth. These treasures can also be regarded as a feature of the secret realm labyrinth, which is specially made by the Jinkisi Chamber of Commerce in order to distract adventurers from the maze itself. If there are treasures in the labyrinth, it is easy for profit-seeking adventurers to focus on acquiring the treasures in the labyrinth and ignore the secret realm of 'not knowing if there are treasures for the time being'.

In addition to the first and second floors, the third floor has been mostly completed, but the lack of mercenaries makes the third floor temporarily unable to play its due role even after completion. The remaining six floors, which have not yet begun construction, are directly like a large empty cave, and the passage to the upper floor can be seen almost at a glance.

Shi Leiyin's task is to clean up the maze area of the first layer of West Thirty-One District. Although there is no set time for the task, it is clear that the faster you do it, the sooner you can take on the next task. Therefore, after taking down the mission, Shi Leiyin planned to start the mission immediately.

However, the maid in the service area told Sù Shi Leiyin that the area he had chosen was temporarily unstable and could only be entered after the mercenaries in charge of the sweeping mission could deal with it. Fortunately, when these tasks are released, they are all situations where the sweeping tasks have been completed or are about to be completed. Shi Leiyin only needs to wait an extra hour or two before starting the mission.

For this kind of regulation to protect newcomers and low-strength mercenaries, Shi Leiyin has no way to refute it. Even if he thinks that his strength and ability to escape will not be in danger of his life in the labyrinth. You only need to wait an hour or two to have a safe working environment, so why not.

While waiting, Shi Leiyin asked the maid in the service area about the ten non-repetitive tasks of the trainee mercenary. In fact, No. 37 can also answer this question, but because the maids of the Chamber of Commerce are almost indistinguishable in appearance except for the color of their hair and clothes, and the maids in the service area happen to have the same green hair color as No. 37, Shi Leiyin subconsciously asked the other party as No. 37.

As Shi Leiyin expected, the trainee mercenary's ten non-repetitive tasks can be completed by taking on ten different area cleaning tasks. And the cleaning task is indeed a repeatable pick-up task. After a Cleanup mission is completed, after more than 10 clashes between mercenaries and invading adventurers in that area, a Cleanup mission will be issued again to deal with battle traces and bloodstains. However, if it is confirmed that there are groups of more than three adventurers or a total of five or more individuals in the area, the cleaning mission will not be posted, and the blue cleaning mission will be released first, and the cleaning mission will be released after the cleaning is completed.

Shi Leiyin's luck this time is not very good, because this cleaning mission has been released for a while. Usually the area where the cleaning task is issued, the surrounding area maze will change its direction, so that adventurers are not led into this area and there are accidental casualties of the cleaners. And just before Shi Leiyin took over, an adventure group of ten people unexpectedly entered the area. Therefore, an urgent blue sweep mission was released, and the only advantage of such an urgent mission was that the number of chamber points was ten percent more than that of ordinary tasks, so it was quickly taken over by mercenaries who were familiar with the situation.

Just before Shi Leiyin took on the task, this blue task had already been reported to be completed. And the time that Shi Leiyin needed to wait for was just the time it took for the investigators of the Chamber of Commerce to determine the process and the exact situation of the mission.

It didn't take an hour for Shi Leiyin to get the news that he could enter the area. And this time, the mercenaries who completed the blue mission have a very high degree of completion, and all the ten adventurers confirmed have been captured, so Shi Leiyin does not need to worry about the appearance of fish that have slipped through the net in the area and affect his work. Of course, there is no way if a willing adventurer breaks in during the cleanup.

Even if it was a clean-up mission, you could take a teleportation array to get there, which Shi Leiyin didn't expect. However, thinking that even if he ran at full speed, from the ninth floor to the area of the first floor, without the maze in the area, it would take at least two days to run in a straight line, Shi Leiyin suddenly felt that he had become stupid.

This time, the teleportation felt much shorter than when he teleported to the secret realm before, and almost as soon as the white light flashed in front of him, Shi Leiyin found himself in a large stone house.

Before entering the teleportation array, Shi Leiyin had already learned from Thirty-Seven that the teleportation array was a one-way teleportation, and would randomly teleport to one of the ten teleportation points in the target area. And this stone house is a special setting that can only be entered and exited, depending on the size, it is an entrance for combatants.

In addition, Shi Leiyin also has an extra white stone on his body, which is called the Labyrinth Return Stone, a special teleportation stone in the maze, and the only function is to allow the user to teleport to several locations with teleportation arrays hidden in the first layer of the maze.

The return stone on Shi Leiyin's body has been magically bound, only Shi Leiyin's magic can be activated, and after each use, it must be returned to the mercenary union to be reactivated. So unless you are in danger, you can only use the return stone to return when you have completed your work.

Out of instinct, Shi Leiyin wanted to try to see if he could devour the fusion of this teleportation stone to obtain the ability of spatial teleportation. However, after being told that if the stone was lost, it would cost 100,000 points to apply for a replacement, so he temporarily abandoned the idea.

After leaving the stone house, Shi Leiyin immediately smelled a smell of blood, apparently the team of adventurers who had accidentally entered was caught by the mercenaries in charge of the sweep near the stone house.

Sighing at his luck, Shi Leiyin moved in the direction of the smell of blood.
