There is no constant temperature system in the public classrooms of the complex, of course, not because the hospital cannot afford to install this system. According to the original designer's original intention, the flowers in the greenhouse would not stand the test, so the temperature of the classroom here is about the same as that outside.

However, since these people are students of military academies, their physical fitness is generally not bad, and the usual low temperature does not have much effect on them. It's just that at this moment, everyone's hearts suddenly felt a chill. They understood the meaning of Professor Ax's words, and they should not be able to complete the task without hard work.

The assessment of the First Academy is naturally very strict, and if it is not completed, it will definitely have a great impact on them in the future. Although these students are all capable people, the attitude upheld by the First Academy is that the academy is a battlefield, and everyone must be ready to accept challenges at any time! Therefore, even these heavenly pride are not very sure that they will be able to pass every test.

Ye Yu looked at the starry sky map, and his thoughts couldn't help but drift to a far away place, which was the training and garrison base of the Sharp Arrow Battalion. The base is on a desolate asteroid, and as long as you stand on the surface, you can see the vast galaxy. It's just that although the scenery of the galaxy is magnificent, it is extremely boring to watch it for ten years. And at this moment, Ye Yu looked at this starry sky map, his eyes flickering slightly. For ordinary people, the starry sky map is almost the same, but when he is bored, he likes to look at the galaxy, and he understands that there is no exactly the same starry sky map in this world.

Although Professor Aix said that this starry sky map was the first time it appeared, Ye Yu saw a somewhat familiar taste. If he guessed correctly, this place should not be far from the asteroid where Camp Arrow was from. Of course, this alone does not make it possible to calculate the location of this starry sky map.

"Bang bang bang-" Just as everyone was attracted by Professor Aix's words, several muffled sounds suddenly sounded in their ears!

"What's going on?" Ye Yu's reaction speed was extremely fast, and he subconsciously realized that something was wrong.

"Ahh

"Enemy attack!"

At the same time, a series of noisy voices rang out in the huge classroom. At this moment, Ye Yu's spiritual power surged out in an instant!

In the next second, Ye Yu's face suddenly showed an extremely shocked look, and in his telekinesis perception, he sensed dozens of extremely surging breaths.

It was also at this moment that Ye Yu finally saw the source of those surging breaths. At this moment, the high-strength glass wall has already been shattered to the ground, and outside the glass wall, the students who were originally watching are squatting on the ground with their heads in their hands. And those who are standing are all masked people in uniform black power suits!

"This ...... LTTE! Chen Tang looked at the people outside, and suddenly opened his mouth wide in surprise.

"They...... How is it possible to break into the First Military Academy! ”

Xia Qiu's pretty and pretty face was shocked at the moment, and she naturally knew about the Tiger Organization. The brilliance of the Federation can illuminate every inch of territory within the territory, but where there is light, there is naturally darkness. The LTTE is one such dark side for most of the Federation, and they are constantly fighting against the Wehrmacht in order to establish a new state within the borders of the Federation. For hundreds of years, there have been many battles between the two sides, large and small. And the civilian deaths caused by this are naturally an extremely horrific number.

It's just that the main force of the Tiger Organization has always operated in the southern sector, which is the farthest away from the home planet of the Federation, and most of the powerful places on the home planet will only carry out some underground activities. After all, this is the home planet, and the defense system is extremely tight.

"Everyone! Or squat! Die or die! ”

Just when everyone was still in a state of panic, a loud shout sounded in everyone's ears. The voice was not as gentle as Professor Ax had said before, and everyone felt as if their eardrums were about to burst.

"Why!" At this moment, a raging flame suddenly rose in the classroom, sweeping towards the person who spoke.

Ye Yu's eyes narrowed slightly, and he immediately saw that the man who sent out the flame attack was also a student of the second class of the first year of the command department. His name is Li Zixiang, a natural flame powerhouse.

"Humph! Insect carving skills! Just as the attack like a fiery dragon was about to hit the man, he didn't see any movement, and the flame disappeared strangely.

Before everyone could be surprised, the big man in black suddenly disappeared with a blur.

"Bang!" At the same time, a muffled sound sounded. Li Zixiang flew upside down to another wall like a cannonball. A huge wound appeared on his chest, blood and internal organs were mixed together, and he couldn't survive.

"If anyone dares to resist, he will end up with him!" The figure of the big man in black appeared at this moment where Li Zixiang was just standing, and a pair of exposed eyes emitted a terrifying cold light.

"The students of the First Academy can't tolerate such humiliation by you traitors!" As soon as an angry voice fell, a thunderclap rang out of thin air in the classroom.

Even in a brightly lit classroom, the lilac lightning that followed the thunder was extremely dazzling. Everyone even couldn't open their eyes under the stimulation of this dazzling lightning!

"Zi-" The sound of a violent electric current flowing!

At the moment when that lightning appeared, it seemed to have eyes, and instantly slashed towards the nearest man in black.

"Ahh

A scream sounded, and the man in black was caught off guard and was instantly struck by lightning. With that scream, the man in black collapsed to the ground, and the smell of burnt paste permeated the classroom.

At this moment, Gao Feng and Ouyang Yi seemed to have made an appointment, and at the same time, they jumped out of the crowd and attacked those black-clothed people!

"Let's get out right now!" Ye Yu looked at the team members around him and said with a solemn expression. He understands that in the face of these men in black, the only thing he can do is to attack and break out of the encirclement! Although Ye Yu faintly felt that something was wrong, the development of the situation was becoming more and more unfavorable, and they had to leave here first.

Ouyang Yi's speed was extremely fast, and just as his body moved, a black shadow shot towards a man in black. Although the combat power of the fourth order of physical art is not very powerful, a full blow is enough to threaten the lives of these powerful black-clothed people.

And just as Ouyang Yi had just acted, dozens of capillary needles seemed to have eyes, and they hurried towards the front door of those black-clothed people. In just an instant, the two outstanding students of the command department worked together to break through the encirclement of the man in black.

"Summer and autumn, come to rain!"

Ye Yu knew that his current combat strength was difficult to break through with his mental power alone. He glanced at Nasha and said, "Since we are a group, we naturally have to work together!" ”

Nasha didn't speak, but Ye Yu felt the rising energy aura in her body, and nodded, "Chen Tang, Wang Jiu, you stand by my side!" ”

"Wow-" A rainstorm fell in an instant with Xia Qiu's movements, as if it was cooperating with the thunder just now. The entire classroom was instantly covered with a huge amount of rain, and everyone's vision blurred for a while. It's just that Xia Qiuqiao's face is pale, as if she is going to fall down at any time.
