Boom, a strong explosion sounded in Quancheng, and the people who turned out to be in the shelter finally fired a cannon after studying for a while, but the accuracy was not very good, and then the marked place was knocked down, but it was shocked by the power of the cannonball.

Qi Fei shook his head, the accuracy was too bad, too far away from the mark, if it weren't for the fact that the cannonball was strong enough and powerful enough, it would be impossible to destroy the marker.

"It's a pity that I don't have time to practice." Qi Fei shook his head, the zombies not far away were already a large group of black pressure not far away, and the roar of the zombies could be faintly heard at the location of the shelter, and now they were standing in the newly built urn city, with forty mortars on it, a row looked very powerful, but the number was less than that of the Xiadao army, but it was the Xiadao base that began to be researched and manufactured shortly after the end came, and it took a long time to have a hundred or so.

The alarm in the shelter has been sounded, and all the people of the supply team have gathered together and come to Weng City, the number of mortars is not enough, but it can be coordinated by many people.

However, the training time was too little, and there was no experience in cooperation, which seemed a bit chaotic, but soon everyone adjusted and waited for the arrival of the zombies.

Liu Bi looked at the group of zombies slowly coming in the distance a little nervously, he was afraid that there would be a lot of mutants inside, after returning from Xia Island, he had already developed a fear of mutants, especially after seeing more than a dozen mutants on Xia Island, even if Liu Bi asked them to kill three mutants, there were still more than a dozen mutants.

Although Xiadao was victorious in that time, I don't know how many mutants died, you must know that Xiadao has a large number of troops, but there are not so many people in the shelter.

The current shelter is not enough for both manpower and mortars, but these zombie groups in front of them are no less than the one on Xiadao.

However, the shelter now has an advantage that there is a lot of ammunition, and now Liu Beep has a lot of crystals in his hands, not that Liu Beep does not give the crystals to the material team, but that most of the members of the material team are now second-order, and they are all second-order crystals, and now the first-order crystals are used less.

"Qi Fei is almost there, otherwise let them let them try it first." Liu Bi looked at the zombies that had already been very close, so he asked Qi Fei to let go of a shot and try it.

Qi Fei nodded and then shouted to aim and fire, and then everyone aimed first, and then waited until they were aimed, and then fired one by one, although some of them were very slow, not with most of them, it was a little strange after all, Liu Beep saw the Xiadao army fire artillery at about the same time, and the bombardment sound was very strong, but now it is a little embarrassing.

And the accuracy was not very good, only a few shells of forty mortars hit, and most of them were too close.

"Ahem." Qi Fei was a little embarrassed, but he couldn't help it, and the total training time they had only been training for more than a day was already good.

"Forget it, let's wait until those zombies are closer." Liu Beep also shook his head helplessly, there was really no way to be such an accurate head, but Liu Beep didn't accuse them of training too short after all.

Although Liu Beep didn't say that they were a little embarrassed, everyone also knew that they were a little embarrassed, but as long as they fought well after that, and this time they had already made the trajectory after that, as long as the zombies arrived at that position, they could use mortars to attack wildly.

The zombies are getting closer and closer, and everyone can already hear the roar of the zombies and the smell of decay on the zombies.

"Fire!" Seeing that the zombies had entered, Qi Fei immediately shouted to open the cannon, and when they heard Qi Fei's voice, they immediately opened fire, this time it was obviously much better than before, and the shells all entered the zombie group this time, and the artillery fire hit the zombie group, and many zombies were bombarded by the cannonballs.

"Haha, that's it!" Everyone saw the shells enter the zombie herd and kill the zombies, they were happy and shouted, and those who controlled the mortars were also very happy, but the zombies were already approaching, this time was not the time to celebrate, quickly loaded the bullets and prepared for the next shelling.

Boom again, the shell attack exploded in the zombie group again, more zombies were bombed to death, and everyone was happy again, but Liu Bi was a little worried, although the two shelling bombardments killed a lot of zombies, but now those zombies are still a group of black presses.

"There are so many zombies." Zhang Yaxuan, who was watching from the side, also sighed a little, when he saw the shelling of Xiadao, the zombie group was directly hit into a big vacuum, and they shelled it twice, and now there are so many zombies.

"There's no way, so many mortars on Xiamen Island are different from ours." Liu Bi could only comfort himself like this, he didn't want to guess why there were more zombies this time than the one on Xiadao.

"Quick!" Qi Fei shouted, asking everyone to load quickly, but although they have been trained, it is impossible to be too skilled in such a short time, and even some of them are even slower to reload because they are too excited.

Fortunately, the third shelling finally came.

"No, those zombies are about to get to the city." Seeing that the zombie group was about to arrive at the city of Wengcheng, some people began to suffer, but Liu Beep is not stupid, he has already made a mechanism in front, and he has a system to make the system dig a big pit in the pinching surface, if those zombies go in, they will die.

"Don't rush, get the Molotov cocktail ready!"

Seeing that the zombies were getting closer and closer, but suddenly the ground in front of them collapsed, and many zombies fell into the hole, and only a small number of zombies that did not collapse in front of them could continue to move forward.

At this time, countless Molotov cocktails were thrown, all of which were made of collected wine, and a lot of wine had been collected before, except for a few that were exchanged, all of them were made into Molotov cocktails.

The Molotov cocktail was thrown out because of the huge force, and it went directly into the cave that collapsed, and instantly it caught fire, Liu Beep also added some gasoline to it, and the group of zombies continued to rush into the hole, looking like they wanted to plug the hole directly.

But I didn't expect Liu to use the trick of burning, so that more zombies were burned to death, and mortars had more opportunities to attack.

"The mortars continue to attack in the distance, and the others and I will go down and get rid of the zombies below." Seeing that the plan was almost over, Liu Beep asked Qi Fei to stay and command them to continue shelling the zombies in the distance, while he took the others to get rid of the zombies below.
