Everyone discussed for about a day, and discussed all the details of the entire operation, and the jade slip that Xiao Shuqi did not share contained information about some dark chess pieces in the enemy camp, which was not suitable for everyone, so he did not announce it directly, but mentioned the information of several monks who could be contacted for the time being. Pen & Fun & Pavilion www.biquge.info

After everyone agreed on the details, they left the camp together, found a secluded place, and after swallowing the Demon Pill, everyone sensed each other's situation, and confirmed that they did look no different from the Demon Race at this time, and then took the Transformation Pill respectively, so that their respective appearances turned into the appearance of the Demon Race in their plan to replace the Demon Race.

Mo Li's illusion is a demon that resembles an ape, and the body itself is very short, so for her, the change in body shape is not very much, at least the changed demon is still similar to her original body shape, but the demon clan that Su Liuyun changed is the brave and warlike mountain demon clan in the demon clan, which looks like a moving hill, and the volume is not much larger than himself, so that Mo Li has to marvel at the miraculous effect of the transformation pill, and I don't know where the extra mountain-like muscles on Su Liuyun's body came from.

I have to say that the efficiency of the upper echelons is very high, they only took three days from signing up for this mission to gathering, they were able to arrange everything properly, and found a suitable replacement demon according to the characteristics of each person, and investigated and sorted out the relevant information of the replaced demon race, and provided them with an understanding in advance, so as to avoid wearing goofs when disguised.

After everyone left the camp, they hid their bodies all the way, and finally arrived safely at a place ten miles away from the demon camp, where they found a demon disguised by a monk, this monk has been lurking in the demon camp for a long time, mainly responsible for the investigation of various news and the communication and liaison between the hidden monks, he is the person responsible for connecting with them this time.

Because Mo Li needed to observe the formation inside the Danta at close range, her identity was one of the demons on duty in the Danta, and their team of twelve people was also divided into two groups, one group borrowed the identity of the monk on duty inside the Danta, and the other group borrowed the identity of the patrol demon clan outside the Danta.

The people of the joint arranged it very properly, although the team they entered were all original demon people, but the timing of their entry was just right, they had not been on a mission before, and when they came to the demon camp, it happened to be their time on duty, and the demon clan whose identity they had taken up had been completely controlled.

Seeing such a perfect arrangement, Mo Li had to suspect that there were undercover agents on their monk's side in the upper echelons of the demon army, otherwise it would be absolutely impossible for the monks lurking at the bottom to achieve such a point.

……

Following the demons of Mo Li's team to the outside of the Danta, she couldn't help but keep her eyes on the outermost formation carefully, after all, the information she got from a person who was not proficient in the formation would be more or less distorted, and to be foolproof, she had to check and judge it herself. After all, for formation mages, everyone's habits are different, even if the same formation is laid out in the hands of different formation mages, there will still be some slight differences, and if this little difference is not taken into account, there may be unexpected situations when the formation is broken.

Although Mo Li is a demon stationed inside the Dan Tower, and she has just arrived at the demon camp and will enter the inside of the Dan Tower to guard not long after, she only has a quick glance at the outermost formation, but her formation attainments can be determined that this outermost layer is indeed the Five Elements Isolation Great Array by relying on those few glances, including the personal habits of the formation mage who prepared this formation, she has also seen through, so it is easy for her to break this formation without spending any energy, and even making the passing array key is a breeze.

The on-duty demons inside the Danta rotate every three months, and everyone is already an old face, and they have identity cards to confirm, so there are no twists and turns in the Danta when they enter the Danta, and no one would have thought that there would be monks disguised as demons to blend into the Danta, and it was not one or two.

At the gate of the Danta, a team of demons on duty, they opened a passage from the inside, and let their demons enter it in this shift, and after everyone met and made a simple handover, the previous team of demons handed over to the captain of Mo Li's team twelve keys that passed through the Tiangang Absolute Array, and then left the Danta.

After the leader of their team distributed the array keys to everyone, he said to the two demons, "It's still the old order, one group guards the door, the second group is on the first layer, the third group is on the second layer, the fourth group is on the third layer, the fifth group is on the fourth layer, and the sixth group is on the fifth layer, and they will rotate in turn after half a month." ”

After the demons nodded their heads to indicate that they knew, the two demons in the first group guarded the place where the outermost formation could be opened, they were the first line of defense of the Danta, and it could be said that every demon who entered and exited the Danta had to pass through them.

Mo Li's six people who disguised themselves as demons were in the second, third, and fourth groups, that is, in the first half month, they had to patrol and guard the first, second, and third layers respectively.

Except for the two people in the first group, the rest of the demons entered the Tiangang Absolute Evil Array together with the array key, and Mo Li took this opportunity to take a good look at the internal layout of the Tiangang Absolute Evil Array, and from the details, she could see that this formation and the outermost Five Elements Isolation Array were from the hand of one person, after all, the tiny habits of these two formations in the details were almost a mold, and it could almost be regarded as a personal signature of a formation mage.

After a while, everyone passed through the Tiangang Absolute Evil Array and came to the real internal space of the Danta, and at this time, they could already see the demons walking around inside.

Mo Li and Su Liuyun were in a group, they happened to be the second group, so the two of them needed to stay on the first floor of the Dan Tower for the first half a month, patrolling and guarding here, and it was only after a month that the two of them could take their turn to go to the fifth layer, and only at that time could Mo Li have the opportunity to carefully observe the third formation inside the Dan Tower, and only then could she judge whether they could complete the task within a year.

The first layer of the Danta is an open space, and there are the most demons in it, there are no public defensive formations or prohibitions here, some are just earth fire furnaces, and the alchemists in the demon army will conduct alchemy here, the difference is only that some are completing the tasks of the troops, and some are refining the pills they need.

Because the level of earth fire here is the lowest in the Dan Tower, the grade of the alchemists is not high, and they are not too shy about the other demons around, so there are very few who bring their own array disks for isolation, and basically they just find a random earth fire furnace and silently start alchemy.

And the space of the first floor is also the largest, on the far right is a staircase leading to the second floor, but this staircase is not up, but extends to the underground, that is to say, although this Dan Tower is called Dan Tower, but in fact, except for the first floor above the ground, the other floors are not above the ground, but extend to the ground layer by layer. In fact, it is not difficult to understand, after all, the reason why this Dan Pagoda stands here is nothing more than because there is a fire vein underground, and the closer to the fire vein, the higher the grade of the earth fire. From this, it can also be guessed that the Demon Spirit Pill must be a high-grade elixir, otherwise it would not be at the fifth layer of the Dan Tower, blocked by the formation that everyone did not understand.

In fact, it is said to be a patrol, and normally, a demon like Mo Li and them stationed on the first layer only needs to find a place to close their eyes and recuperate. If there is a special situation or any unexpected incident in the first layer of Danta, they can deal with it as soon as possible. According to the information Mo Li obtained, there has been no situation in this Danta for thousands of years, so the task of guarding the Danta can be regarded as an idle errand, but the three months on duty cannot really meditate and cultivate.

There was no communication between Mo Li and Su Liuyun, Mo Li's entire body and mind only needed to be placed on the formation, so Su Liuyun was responsible for guarding the surroundings, and at the same time paying attention to the every move of everyone in the Dan Tower, after all, every demon who entered the other layers had to pass through the first layer where they were located, and under careful observation, they could also grasp some rules, and maybe the actions after that could have unexpected effects.

And after Mo Li closed his eyes, he was thinking about the problem of the two-fold formation outside, the Five Elements Isolation Formation is easy to say, for Mo Li, it is very easy to refine the array key that can pass through this array unimpeded, and it can even be said that she can also transform this array, so that the original control hub will not work, and not only will this array not be able to block a few of them, but it can also become a barrier for them to block the demon race.

And although the Tiangang Absolute Evil Array is very easy for Mo Li to break it, it will inevitably attract the attention of some people after this array is broken, so she needs to deduce the array key that can pass through safely and make it, but this is not difficult for Mo Li, after all, she has the template of the array key in her hand, which can be used as a reference. But Mo Li didn't want to be limited to this, for a person like her who was proficient in the formation path, what she wanted to do was to be like the Five Elements Isolation Array, not only to make the array key that passed through this array, but also to be able to modify this formation slightly, and then use it for her.

For a clever array mage, it is not difficult to break the formation, and it is not too difficult to make the array key, but it is not easy to transform a formation that has been formed so that the formation can be used by her, so Mo Li needs to use the current time to deduce and come up with a feasible plan.

Half a month passed very quickly, and Mo Li still couldn't deduce a method that would not be discovered by the other party, but could completely use the big array for her use, so she and Su Liuyun had their turn to guard at the door, and at this time she didn't have a chance to close her eyes and recuperate the formation.

After all, Mo Li's cultivation seems to be a big step lower than Su Liuyun's, guarding the door, when there are only two people around, it is absolutely impossible for her, the person with a low cultivation, to do nothing, but let the one with a high cultivation be busy opening the formation for others and checking their identities, otherwise there will definitely be careful demons who will notice their abnormality.

In this way, Mo Li also had to join Su Liuyun to observe the ranks of the demons, it can be said that all the demons who entered and exited the Danta in this month passed in front of the two, but Mo Li did not open his eyes to observe in the first half of the month, but these people all entered Su Liuyun's mind.

……

For Mo Li, she finally survived the first month, she could finally go to the fifth layer, and she could finally see the actual situation of the formation that no one could judge, it was impossible to say that Mo Li was not excited, after all, for the formation mage, the more high-level the formation, the more difficult the formation, the more impossible the formation to comprehend for a while, the more attractive it was to them.

In the process of rotation, Mo Li and Su Liuyun passed through the other layers, and at the same time paid attention to the situation of the other layers by the way, it can be said that except for the fifth layer, there is no other prohibition protection inside this Dan Tower, but with the increase in the number of layers, the area of each layer will be reduced, and at the same time, the number of earth furnaces inside will also be reduced accordingly.

For example, there were enough earth furnaces on the first floor, but the number of earth furnaces on the second floor was drastically reduced to only fifty, and the number of earth furnaces on the third floor was halved again to only twenty-five, and the fourth layer was exactly ten earth furnaces, and when Mo Li passed them, there was only one alchemist on the fourth layer who was alchemizing there. The fifth layer, that is, the most important place of Danta, only has one earth fire furnace, and special talismans are also required to enter and exit it, at this time, the sixth group, that is, the group where the captain is located, handed over the two talismans to Su Liuyun and Mo Li, and left the fifth layer.

When Mo Li and Su Liuyun entered the fifth layer, there was no alchemist in it, but because they didn't know if there were any special objects in it, they didn't dare to be too casual, but they just acted as if no one was there, and they could be a little lazy, but in fact, they were constantly checking the surrounding situation with their divine sense.

Su Liuyun observed the layout of the fifth layer and the things inside, you must know that this fifth layer is completely different from the other layers, some of the other layers are just earth fire furnaces, and the monks all bring their own materials to come here for alchemy, and at the same time, after refining the pills, they will also take the pills away, so the first to fourth floors are just earth fire furnaces. On the fifth floor, except for the most central earth stove, except for the side where the stairs are located, there are several shelves against the wall in the other three directions, and on the shelves are all kinds of spirit grasses, materials and elixirs, and the number is not too small.

Su Liuyun carefully observed the things on the shelves, there was a layer of prohibition protection on the outside of each shelf, but it did not affect people's sight, so he could only look with his eyes outside the prohibition, and he did not dare to touch that layer of prohibition easily, who knows if it will be discovered by others after touching it, this is not the time to act rashly.
