The crystals brought by Master Ping are not small, and the types covered are quite complete. If you concentrate all these weapons on the house that Nina built. Their humble wooden house with walls has become a veritable fortress!

In a hurry, Nina and the others didn't have much arrangement, but simply used all the array weapons according to the existing structure of the fortress they had built before. The crystals were all stuffed into it, and most of the students who returned to the camp were on the second floor, ready to go.

Their affairs had just been dealt with, and they didn't breathe. Dense voices could be heard in the distance. The sound came out like a huge mechanical monster, moving its huge body, shaking countless metal parts, gradually approaching them.

The black shadow that appeared in the forest gradually became clear, and there was more than one demonic beast! The number reached ten! What is the concept of ten, this is equivalent to the number of patrolmen!

There are too many demonic beasts arriving! Even a third-order strength mentor has brought a considerable burden! Their skin is thick and thick, and the attack effect of third-order cultivators is not very impressive! If so many demonic beasts rush in, it will have to be a lot of third-order mentors to resist them!

The students couldn't help but be very worried! Even if the lazy mentor was still here, if he faced so many demonic beasts, he might also have an accident in the battle! If he cares about this side, he can't take care of that side, and if he is negligent, he will be extremely easily injured by the long thorn cone of the pointed demon beast! Not to mention that the mentor is still mixing potions, and he has left a lot of things to resist the demonic beasts to them!

It's impossible!

"Huh!" Nina, who was standing on the second floor and was the leader, immediately launched a magic technique against the demonic beasts that walked into the activity area. Her face was as usual, just like the expression she had when she fought with the demonic beasts before, she didn't change much, and she was still very calm and calm!

The students on the side also reacted quickly and launched magic bombs at the monster one after another. Their power is still small, but if they attract the attention of the demonic beasts, it will be enough. If they enter the activity area and disperse quickly, it will be a big problem for the other classes.

The collective attack of multiple students has clearly had an effect. The more than a dozen demonic beasts were originally focused on other places, and they were about to go somewhere else. But now, all their attention is slowly focused on Nina and the others on the second floor.

The distance between their position and the outer forest was not long, and after being provoked, the pointed demon beast lifted the thorn cone and strode over.

The students of Class 7 couldn't help but feel a little happy when they saw that the demonic beast they attacked was able to come over according to their thoughts. This effect is as if to say that their strength level is no longer a falling leaf falling on the demonic beast without any feeling, and it is also a little powerful.

Of course, even if the students of Class 7 knew that there were many second-order arrays around them, which could effectively defend against demonic beasts for a while, they still seemed a little lacking in confidence when they were fierce and standing on the ground, and the horizontal height of those two eyes could still exceed their heads.

Under the gaze of the demonic beasts, they all couldn't help but take a small step back.

It's impossible to be afraid, you know, these monsters can directly kill them with a single blow!

The students of Class 7 looked at the defensive arrays around them and couldn't help but worry again. They didn't have any of the array weapons they were wearing, and the demonic beasts had broken into the fortress, and it was hard to imagine how they could resist!

At the same time, although the number of these array weapons is quite large, the crystals brought by Master Ping are also first-order and second-order crystals. However, there are no more than ten of these arrays! Many of the functions are duplicated! And there are more than a dozen demonic beasts, how can they use these arrays to resist demonic beasts?

The worries of the students of Class 7 seemed to be a little unnecessary, and the first step of the demonic beast rushing into the activity area was triggered, and the first trap array brought by the lazy mentor was triggered.

When they were attacked and assembled into a unified team, the trap was also maximized.

Of course, the traps near the distance are not focused on attacking, but on trapping monsters.

A thick milky white smoke erupted from the area where the monster was located. Let their vision be completely unclear in a short period of time, and at the same time, the boiling of water vapor also obscures most of their sense of smell in the air, making them lose their two senses, plus the students see the monster entering the trap, the atmosphere is not daring to come out, so that they can not catch normal sounds, can only walk around in unknown directions.

Class 7 students stared firmly at the 'Misty Net' in front of them, and its range was quite huge! It was also the first part of dealing with the monsters: disorienting them. If they can figure out where they are at this time and take the initiative to go back, that would be the best.

Even if they didn't look back, the students guessed that the time that the monster had been trapped should have been more than ten minutes. It's like if a student stepped into this kind of array alone, they would probably be trapped for a few hours!

Inside this array, the mist appeared so suddenly, and it was so dark that it was impossible to find the direction with any external objects!

Moreover, the ground under the foot looks effective, and the position can be determined by using the method of knife carving. However, the aerosol effect of the misty net itself is caused by the boiling water vapor in the ground, and when the effect is generated, the ground will become extremely wet, and even if there are nicks, it will quickly mix with the mud and become unrecognizable!

Although the number of Warcraft entering is relatively large, they are not able to carry out more complex cooperation. Especially when there is no king!

Can...... In less than a minute, the first demonic beast broke through the white mist in vain and appeared in front of the students!

"This!" the students standing on the fortress watched in disbelief as the beasts continued to walk in their direction one after the other. Although the misty net is a very common array, many students will use it during training, but this also shows the practicability of this array! It is the most cost-effective array.

Could it be that the Warcraft doesn't think too much about it? From the first time they see them, the Warcraft will only move in this direction towards them, and until the prey is captured, it will not easily change its goal due to external forces?

The white fog dragged on for less time than the students expected. However, the students understood that there was not just one formation weapon brought by the lazy tutor.

"Bang!!" After the monster stepped out of the white mist, an explosive trap full of traps followed. The first demonic beast seemed to be caught off guard, and it was blown up, and Kankan took two steps back. There weren't just one or two small fragments buried under the traps around them, but a few traps that were a first-order or second-order fire-based crystal!

The monster can be blown back by the trap, which is exactly what the students expected.

The place where the fire crystals are buried is in the hollow of the field, where the crystal traps are laid from beginning to end. At the beginning, the students didn't know where the monsters would come from, so they had to put everything they could!

If all of these traps are used, it can be a great help in delaying time!

However, the demonic beasts did not flinch much from the traps, and they did not even have the idea of exploring the path and going around in circles! More than a dozen demonic beasts actually stepped directly on the area full of traps and walked over! There was no intention of being blocked by the traps!

There are too many of them! One of them is blown up and the safe monsters behind it bypass and go up! Their advance is extremely fast!

The students' eyes widened! At this rate, it didn't take more than a few minutes to reach them!

The students were in a hurry. At present, in the case that the Lazy Master has not yet finished, he must immediately find a way to make the Warcraft stay longer!

These are the only traps that can be used at the moment. The bursting trap is not the same as the White Mist Array, and if they are all used, the time saved is considerable! It can give them an extra ten minutes! But...... What do they have to do to get the monster to take the initiative to take a long detour and step on those traps? It's impossible, right?

Although, they also have a way in their hearts, that is, to let one person be used as bait to lure more demonic beasts to disperse into the trap on the side......

However, if you want to be used as bait, you must enter the central area full of traps! Wander on top of the traps that are enough to blow them up to serious injury! Below the traps are first-order and second-order fire crystals! If the force of stepping down is too great, the power that bursts out is not a joke! Not to mention that the power of the broken crystals before is comparable!

The hesitation of the students of Class 7 could not stop Nina's actions. She looked at the students' hesitant expressions, and jumped under the fortress without saying a word!

Nina's movements and the attacks released by the trend still attracted the attention of some monsters. Although there are more of which demonic beasts, because of the blocking of traps, the speed is obviously not able to keep up with Nina, who is swimming smoothly in the field.

There may have been a lot of traps buried, and Nina was walking on the edge of this trap that could blow off the monster! If she stepped on it, she would probably be hurt no less than the two of them!

In the face of such a risk, Nina still calmly ran on the edge of the trap full of ground.

It's not a clair-see-through feature that allows her to look directly into the traps underground. However, she was not the only one who did the trap, and the rest of the students also laid most of the positions from the outside to the inside!

Therefore, Nina ran on the field full of traps with such a calm face, and the most important thing she relied on was that they learned how to eliminate traps in the previous lazy tutor's courses!

At that time, the lazy mentor taught them how to dig, not how to avoid pitfalls. The two sides may be different areas. But it was precisely because of the risk of physical injury that they also gained a lot of knowledge!

Just like at present, the burial of traps seems to be buried by many students together, but there are still certain rules for the location and way of burying!

Nina carefully calculated what she knew.

First, the traps cannot be placed together closely, not only to prevent the series of traps from being connected in series, resulting in a trigger and chain explosion, but also for the convenience of burying. Of course, this also confirms that the space for stepping on the foot must be enough, compared to the big soles of the monsters, the probability of Nina stepping on it has dropped by half directly!

Second, the trigger strength of the trap. If the trap explodes immediately when touched, then the trap will be dangerous when it is buried again, but in fact, although you need to be very careful when burying it, it is not very dangerous.

Pushing in reverse, Nina only needs to be calm when stepping on the ground around her, and she can't rush to the ground with her toes impatiently, which can reduce and avoid the triggering of traps.

Thirdly, the most important thing about the traps is that they are buried underground! There is still a very rare time interval between the explosion of crystals and the impact of attribute power on the upper layer of the earth! When Nina leaves the place, as long as the speed is pulled fast enough! Then even if the trap is triggered, she can quickly escape from the place and avoid injury!

Just like in the past, the lazy mentor asked them to dig with a shovel, seemingly using a tool, which made it more difficult to detect the trap, after all, when the hard metal hits the trap, it is easier to trigger the fragmentation and explosion. But the purpose of the lazy mentor is to minimize the danger for them, and the key is to give them time to protect themselves!

And the magic power she is currently using is obviously the best way to use it!

Warcraft doesn't understand these things at all, they will only stay for a moment when they step on the trap, and continue to move forward cautiously!

At present, several students saw Nina's performance, running on the ground almost very smoothly without a single explosion of the trap, and suddenly understood a lot, and jumped off the position of the fortress. They seem to be able to delay for a long time!

Still, they knew it in their hearts...... Although the traps were buried around the clearing, there were also many of them. However, they can only be used once! The speed at which the ten beasts advance is not slow, and the trap will eventually be used up at a time! If by then, the Mentor has not yet come out of the fortress...... So, what should they do......
