The steps in front of the library, the flower beds, and the cobblestone paths were all lifted and destroyed. The moist black soil was like a sleeping giant finally waking up, and quickly straightened its back.

In less than half a minute, the earthen wall was more than two stories high, not only enclosing the front of the library, but also covering the window where the female zombies had entered the library before. There was no light in the library, as if the entire building had sunk into the ground, forgotten, to be turned into oil after 10 million years.

The zombies gathered in front of the library naturally suffered as well. Some zombies are right above the earthen wall, and they are lifted along with the earthen wall. Although the earthen wall was thick enough, the top was not as flat as the brickwork. Zombies fell from the wall, and the distance of the fall was as high as a three-story building, and even if they didn't fall to their death, they would break their tendons and fractures, so don't think about moving anymore.

However, not all the zombies that were raised by the wall fell. The soft dirt wrapped around their feet and around their waists, and before they could struggle out, the dirt quickly dried and hardened. Just like before the end of the world, some people liked to insert some glass pieces into the cement of the wall when they built the wall, so that someone would not climb over the wall, and these zombies probably could play the same role.

More zombies were kept out of the earthen walls. The sides of the earthen walls also dry quickly, making them as hard as dry cement. No matter how much the zombie scratches, it just grinds its claws into flesh.

However, it is only against the outer wall that dries it. The wall that clings to the library is still soft, not only does the earthen wall stick firmly to the outer wall of the library, making it stronger, but also a large amount of black earth pours in from the main entrance of the library, engulfing the ordinary zombies in the hall on the first floor of the library, and then hardening quickly as usual. The ordinary zombies in the library hadn't figured out what was going on, like raisins stuck in bread crumbs, sealed in the dirt and unable to move.

For a moment, the library was filled with the smell of earth.

With the roar of the zombies, the flavor is even better!

For a moment, the library was deadly silent.

Whether it's a zombie or a living person, they can't believe their eyes.

Who made this earthen wall? In just a dozen seconds, the battle situation was completely reversed!

"Whew!"

The silence was soon broken. Not all zombies are engulfed in dirt. These brainless ordinary zombies howled and pounced on the flesh in front of them.

Wei Ru clenched her fists excitedly, killing zombies is more efficient!

The zombies outside couldn't get in, and most of the zombies in the house were trapped in the mound again, leaving seven or eight miscellaneous fish, which was also a matter of exercise after dinner for her!

"Quack!"

The female zombie suddenly rushed to the study room on the second floor of the library.

Wei Ru downstairs was stunned and immediately shocked. Sun Kai is inside

！ I couldn't understand how she did it, but she could have made the earthen wall!

Could it be that zombies have figured this out too?!

Not daring to delay in the slightest, Wei Ru rushed to the study room on the second floor.

The mute girl who had rested a little also followed. Behind them, the only two ordinary zombies left in the library desperately moved their stiff legs, but unfortunately they couldn't catch up with the two living people, so they could only reluctantly stretch out their hands towards their backs.

But the zombie speed is not slower than Wei Ru, and it is on the second floor, so they have already entered the study room first. They're late?!

Bang!

Just as Wei Ru arrived at the door of the study room, something suddenly exploded in the study room.

Although the explosion was not violent, it was not the kind that could blow up the entire study room, but the smoke and dust blew so that Wei Ru couldn't see clearly, and he didn't dare to go in for a while.

The panting mute girl pushed Wei Ru away and strode into the study room.

"Hey! Be careful! ”

Wei Ru said that it was useless, so she hurried to follow, the window was sealed, and the smoke and dust dispersed very slowly, but the female zombies who could still be identified were frozen by the window, as if they were preparing to dig a hole in the earthen wall outside the window to escape. The mute woman stared at it, restraining its movements. Luckily, it doesn't seem to be smart enough to do that. Although as a zombie, knowing how to run away is already quite scary.

There was a chubby figure in the innermost part of the study room, and next to her was Wei Ran.

Seeing Wei Ru, Wei Ran, who was protecting Sun Kai, shouted: "Get out of the way!" ”

After saying that, he raised the homemade crossbow and shot a small piece of dough at the zombie.

Wei Ru's eyes widened, grabbed the mute girl's hand, and pulled her to run out of the door.

At the same time, Wei Ran and Sun Kai also hurriedly got up and hid in the research room next to them.

The zombie standing at the window struggled to move.

But the mute girl always controlled it. It could only watch as the crossbow bolt with the "dough" on it fell on it, sticking firmly there.

That's not dough, it's plastic explosives. It was also purchased by Wei Ran in the University of Survival in the Last Days. Because it was too expensive, I bought a palm-sized piece.

Wei Ran pressed the detonation switch.

With a loud bang, an abstract painting erupted from the wall of the study room with severed limbs and blood foam, and at first glance, it was quite artistic.

This time, without waiting for the smoke and dust to dissipate, Wei Ru ran into the study room: "Xiao Ran! Where are you?! ”

"I'm here." Wei Ran coughed and walked out of the research room.

The study room in the library was very large, and he hid in the innermost part, and there was a door in the research room blocking it, plus the amount of explosives was not large, so he was not injured.

Wei Ru came to her younger brother, looked carefully from head to toe two or three times, and finally made sure that Wei Ran had nothing to do, and hugged her brother tightly: "We succeeded!" ”

"Yes, we succeeded."

Wei Ran smiled from the bottom of his heart and took the hands of Sun Kai and the mute girl, "We succeeded." ”

Wei Ru wiped a handful of tears of joy and cried, and hugged the dumb girl, Sun Kai and Wei Ran in her arms. "We made it! The zombies have been killed by us! ”

How many times have they felt like they were dead.

The fruit of this victory, in the joy of the rest of the life, is extraordinarily sweet.

"Whew......"

The four of them turned back in unison.

The two remaining ordinary zombies stood at the door of the study room in a daze.

I don't know if it's an illusion, but the two zombies seemed to be frightened by the eyes of the people in the room and shrank back.

After the last two zombies were sent to the western sky, the four of them were finally able to breathe a sigh of relief. After the mood calmed down, the feeling of exhaustion quickly hit.

Fortunately, there are many tables and chairs in the study room, so they can talk while resting.

"Sorry for the delay." Sun Kai said apologetically, "I always failed to meet the teacher's requirements, and I redid it several times before the teacher let me leave class." ”

"Not slow, not slow." Wei Ru waved her hand again and again, "If it weren't for you, we would all have to explain here." What kind of ability are you? Did you really make the earthen wall outside? ”
