At this time, there were zombies everywhere around the wall, so without waiting for Loulan to take a closer look, fist-sized pea shells had already erupted from the three cannon ports at the same time, turning the nearest three zombies into vines.

Almost instantly, the zombies around the vines scattered and fled, as if they had seen a ghost.

Such an attack method is equivalent to one top three, which makes Loulan very satisfied with the upgraded pea shooter, and soon, Loulan noticed that in addition to the increase in the muzzle of the gun, the rate of fire of the pea shooter has also increased significantly, from the frequency of one shell per minute to one shot in about thirty seconds, and the rate of fire has doubled.

As time passed, there were more and more vines around the pea shooter, and the zombie group was gradually isolated, but the pea shooter had no intention of stopping, as long as the zombies were within its range, they were all killed by a resolute bombardment.

Because the attack radius was as high as 30 meters, it took this repeating pea shooter half an hour to completely wipe out the zombies around him, killing nearly 200 zombies and creating a large field of vines.

Although only such a few zombies were killed, it was not because the density of zombies here was not large enough, on the contrary, the density of zombies here was extremely high, and there were at least a few thousand within a radius of thirty meters, but once hit by a pea shooter, the zombies would quickly turn into vines, driving away the surrounding zombies, resulting in far more zombies being driven away than being killed.

After basically understanding the rate of fire and the effect of the Repeating Pea Shooter, Loulan returned to the auditorium and fully informed Principal Xu Wenzhi of the Repeating Pea Shooter's situation.

Xu Wenzhi didn't sleep at this time, since he learned that Loulan left in the afternoon every day and returned in the middle of the night, he developed the habit of going to bed after one o'clock in the middle of the night, that is, he had to wait until Loulan came back an hour before going to sleep, so that Loulan could find him as soon as possible if he had something.

After learning the news of the pea shooter's upgrade, Xu Wenzhi was also very excited, and immediately summoned the teachers of the mathematics department overnight, re-calculated, and finally came to the conclusion without suspense:

It only takes 200 repeating pea shooters to fully guard the campus.

"200 repeating pea shooters, that's still 180 bai!" Lou Lan heard this, his heart was suddenly settled, at this time he already had more than 3,000 zombie brain crystals in his hands, the exchange was not a problem at all, the only thing lacking was the dream treasure, and through the recent period of wasteland work, he also successfully reclaimed fifteen pieces of wasteland, and increased the daily income to as many as 465 fantasy treasures, so calculated, that is, two days of effort, he can completely make up the remaining 180 consecutive pea shooters.

The nightmare life is finally coming to an end!

After learning that Loulan would only need two days to get together the pea shooters, Xu Wenzhi immediately excitedly announced the news to all the teachers and students, and at the same time immediately arranged the preliminary preparations for the recovery of the campus.

For two whole days, the armored car team in the school was constantly busy, and the walls around the school were precisely positioned, and every thirty meters of distance, a burst of pea shooters would be placed, and if the shooters were not enough, a mark would be made, and once the pea shooter was in place, it could be placed accurately.

Two days later, when Loulan put down the last pea shooter with her own hands, she couldn't help but let out a long breath---- it was finally done.

After completing the overall defense system, Xu Wenzhi ordered all efforts to clear the remaining zombies on the campus, and after three full days of carpet clearance, the zombies on the campus were finally completely eliminated.

After all this was done, Xu Wenzhi immediately restored the broadcast system on campus:

"Attention all teachers and students, please pay attention to all teachers and students, please gather at the big playground immediately, please gather at the big playground immediately."

After hearing this broadcast, everyone in the auditorium couldn't help but burst into tears---- our school has finally become our own again.

Nearly 4,000 surviving teachers and students were soon all gathered on the large playground, and they had too many emotions in their hearts for the rest of their lives, and many of them shed tears of excitement.

Standing on the high flag-raising platform, Xu Wenzhi looked around at the surrounding students, couldn't help but have red eyes, and said:

"Students, we survived, although we have also paid a lot of sacrifices, but from now on, our school ----- safe."

Many people couldn't help but cry when they heard this.

Xu Wenzhi continued:

"In order to persevere until this day, we have paid a huge price, there are nearly 4,000 students, paid their young and precious lives, because of their sacrifice, we have today's victory, they are the pride of our university, we will never forget them, our school, our teachers and students, forever grateful to them."

"However, what is more important than gratitude is that we can't let them die in vain, and you may not know that just now, the teachers of the Department of Communication Engineering and several doctoral students have restarted the school's satellite communication center, and we have received a very important good news."

"Good news?" Everyone on the playground, including Loulan, is a little confused, the world has become like this, what good news can there be.

When Xu Wenzhi said this, he suddenly said with obvious excitement:

"Our satellite communication center has re-established contact with the military, and through the information from the army, we already know that the disaster is not as serious as we imagined, and within one kilometer of the coastline on land, it is a forbidden area for zombies, they will not set foot in it, and humans are safe in this area."

"Because of the existence of the coastline, there are hundreds of millions of survivors all over the world, who are gathered on the seaside, with the help of the government, who are rebuilding their homes and resuming production, and at this moment, on the seashore 400 kilometers away from us, there is a large military-controlled settlement with millions of survivors living in it."

Hearing Xu Wenzhi say this, the playground was boiling, the teachers and students who had survived the catastrophe did not know where to go in the future at this time, they were all at a loss, but now they suddenly heard that the government and the army are still there, and there is still a large area of land that has not been captured by zombies, and they suddenly feel that there is new hope for the future, and they all cry with joy.
