After the discussion, everyone returned to the school and went to their own class, and the three people who supported the third and fifth groups followed the members of the two groups to their classes.

The world arrived as scheduled, but due to the noon arrangement, the strength of each group was relatively balanced, so this battle was a great joy, and no one died. The only fly in the ointment was that two more students died in Class 3.

At present, the number of students in each class is 39, 39, 30, 35, 32, 36 and 37 respectively, except for the eighth class.

After two days of fierce fighting, at least one or two students from any group in charge of the class died. Since the three groups were the weakest, the class they were responsible for also had the highest number of student deaths, and now only 25 people remained. Among them, the first and second groups had the largest number of students, and only one person died in two days.

After the battle, Yu Shu and the others gathered together again, and then discussed the content of communication equipment again, and finally decided that Yu Shu, the one-armed captain, and Han Feng would go to the mall to buy communication equipment.

After arriving at the mall, Yu Shu learned that ordinary senior trialists would have the habit of spending trial points to buy some yuan, and as long as the trial copy they entered was modern, this money might be of great use.

However, in Yu Shu's view, this is actually a loss-making business, and it is a proving ground that is pheating them. Think about it, if 10 trial points are exchanged for 10,000 yuan, then 1,000 trial points can only be exchanged for one million, and these 1,000 trial points are enough for the trialist to strengthen his physical fitness.

Money talks.

After walking around the mall, Yu Shu and the three of them successfully bought back a set of communication equipment and assigned a walkie-talkie to each group.

What worried Yu Shu did not happen, and after the world was brought on the third day, Yu Shu found that the walkie-talkie was really not disturbed by the signal and could still be used. It was on this day that the walkie-talkie came in handy as soon as it was used.

On the third day, there is only the morning exam, and the content of the exam is English, so it is not as good as the previous two days, and the invigilator today is two. For the remaining five groups except for the third and fifth groups, having an additional Demon Shadow Squire would only be more troublesome and not pose much of a threat, but for the third and fifth groups, it would be dangerous. Their own strength is not strong, although they are supported by other trialists, but their strength is also the last two groups out of the seven groups.

Through this pair of walkie-talkies, the other five groups knew the danger of those two groups in time, and after solving the monsters on their side, they rushed to the third and fifth groups to support, and successfully rescued the crisis, and no trialists died. Only one female trialist in the fourth group was accidentally injured by a sneak attack during the support process, dislocated one arm, and needed a day or two to recuperate.

On the afternoon after the exam, the senior high school students were in class normally again, and there were obviously a lot of students missing from the classroom, and the teachers and students didn't seem to notice it, as if this was a normal thing.

However, since the students were in class normally, the trialists were not allowed to continue to fight the monsters, which made them happy for a while. It's a pity that the good times didn't last long, and because of the information provided by Yu Shu before, they knew that after the exam, there would also be a world of the inside. So on the third day, at night, the trialists were on guard in the corridor outside their classrooms, and when the students began to do their homework, the shadow slaves rushed out of the homework on the desks, and the teacher sitting on the podium also became the shadow attendants.

There are two periods of evening self-study, each of which lasts more than an hour, and the homework left over for a day is enough for six subjects, so this monster is coming in waves and waves. After the shadow slave that appeared in one homework is killed, the shadow slave in another homework comes out again, and there is another lesson after one class. One night, they were exhausted and exhausted.

The most unfortunate thing is that they have been fighting fiercely for so long, and they are so unlucky that they haven't even burst a key.

And time passed slowly, for several days, repetitive and monotonous days, and the trialists seemed to be caught in a whirlpool of protection and fighting, and it was difficult to break free.

In the next few days, Yu Shu and their second group burst out three black iron hearts, two of which were used for Jiang Qianqian, and the last one was used for Gu Xin'er.

In the past few days, Gu Xin'er has changed greatly. When she saw that everyone was fighting, but she was the only one who had been scared and avoided, she blamed herself; And when she saw Yu Shu and the others fighting every day until they lost their strength, the guilt in her heart was even stronger, growing like a vine in her heart, growing deeper and deeper, and the longer it grew, the more painful it became. She thought of her brother, she had said she wanted to prove herself, so one night she made up her mind that she wanted to be stronger.

In fact, she did. No more dodging, bravely joining the fight, she is young, but her body is strengthened. Yu Shu gave her the MP7A1 submachine gun, and then asked Xu Yingying to teach her how to use the firearm. For this reason, Xu Yingying was also surprised.

In the ensuing battle, Yu Shu and Tang Xuwen took the lead together, Jiang Qianqian was responsible for throwing the monsters downstairs or restraining them, while Gu Xin'er took a submachine gun slightly smaller than her to strafe the monsters and clean them up.

Everyone is improving, Gu Xin'er is improving, Yu Shu is improving, Tang Xuwen is improving, including Jiang Qianqian is also improving.

Moreover, in the past few days, everyone has discussed several times, and according to the plan formulated by Yu Shu, let go of a few Demon Shadow Slaves, and kill the students in front of them after absorbing the life energy and then dying. In this way, the number of students between the seven groups remains at a constant number, and if there is a gap, there is only one or two people at most. If at the beginning, everyone would still be worried, afraid that their group would have the smallest number of students, but now that they have learned how to control the number of students, they are no longer worried.

Everything is going for the better.

Until the evening of the eighth day......

"Captain, here we go!" Tang Xuwen shouted

Without him shouting, Yu Shu also saw clouds of black mist coming out of the homework on the desk, and finally turned into a cloaked shadow slave, standing behind the students absorbing their life energy.

"Let's go." Yu Shu said, and was the first to rush into the classroom as he did at the beginning.

They have fought many times and are almost numb to how to fight. Naturally, after Yu Shu entered, Tang Xuwen followed closely, and when Yu Shu rushed towards the Demon Shadow attendant on the podium, he punched the Demon Shadow Slave by the window.

Gu Xin'er didn't go in, but first strafed the window pane. After shattering all the glass, she jumped onto the windowsill and fired an inflection of shots with an MP7A1 submachine gun in one hand. The gunfire continued, and almost all the shadow slaves were attracted and ran towards this side.

However, Jiang Qianqian stood by Gu Xin'er's side and swept the battle for her. Whenever a monster dared to approach, Jiang Qianqian directly pulled out a whip, rolled it up and threw it out of the teaching building. And even if a monster approaches Gu Xin'er, as long as she activates the life force "Diamond Queen", the amazing defense can make the monsters helpless.
