However, Yin Yu's shooting speed has increased to the fastest. Although one zombie after another fell down, compared with their huge number, it is a drop in the bucket.

When the zombies gradually approached a distance of one hundred meters to the wall, Li Hanlin gritted his teeth and activated the whistle gun not far away.

This whistle cannon, which Li Hanlin had been in the back for a long time, was the zombies in the community behind him. Now it was just the time to come in handy.

The zombies had actually entered the warning range of the sentry cannons, but Li Hanlin had not activated it for a long time. One important reason was that he could not supply the shells of the sentry cannon.

The caliber of the whistle cannon is exactly 20 mm, so it is not impossible to call it a gun, but a whistle cannon with only 100 rounds of shells is easily cut.

Of course, the number of bullets of the sentry cannon is its terrifying power.

The sentry cannon built by Li Hanlin is a double-connected type, which means it has two gun barrels, an ammunition box on one side, and uses a bullet conveyor to input huge 20mm bullets into the gun barrel.

There are two ammunition boxes, one with 100 rounds, and a total of only 200 rounds are only.

As soon as Li Hanlin started, the whistle gun spun and the double gun barrel turned directly to the direction where the zombies were coming.

“bomb!”

“bomb!”

“bomb!”

“bomb!”

The whistle cannon began to roar, and it was no longer the banging sound of guns, but the bombbomb sound of bombs that exploded.

【Sweater Cannon: Damage, 54-68

Rate of fire: 45

Hit: 9

Ammunition: 100 rounds]

The damage seems to be unsatisfactory, but this is not all the damage. The sentry cannon uses 20mm small cannon shells that are stronger than the heavy machine gun. The damage is 6-10, which adds up to nearly 80 points of damage.

This kind of terrifying damage will basically be killed wherever it hits, and it will cause 2 or 3 times the damage caused by hitting an ordinary person.

Of course, there is still a big gap with the reality in Li Hanlin's impression. It is probably because of system construction.

But no matter what, as soon as the whistle cannon became powerful, the zombies that rushed from afar were no different from mixed fish.

The huge power of the whistle cannon is not only hitting the first zombie, but it directly exerted a throughput effect.

That is to say, one hit, one hit, one hit, one hit, one hit, one hit.

Rows of zombies fell down in pieces like harvested wheat.

A distance of only 100 meters was like a natural chasm. A whistle cannon almost fired the effect of gunfire.

Li Hanlin opened his mouth in surprise. This was the first time he actually used defensive buildings. He didn't expect these defensive buildings to be so terrifying.

Comparing them, the human figures he spent a lot of money and used the wisdom core that he had obtained without any channels, and used his talent to inspire them.

But Li Hanlin still said the same thing, and he didn't regret it. If it weren't for them, Li Hanlin might have collapsed long ago.

Although the power of the whistle cannon is terrifying, the zombies have no idea of ​​fear. They have been beaten into meat paste in front of them, and zombies are still coming.

Moreover, it can't stand it for too long by relying entirely on the whistle cannon.

The terrifying power of the whistle cannon comes from its damage on the one hand, but on the other hand, it is because of its rate of fire.

The double-connected gun barrels will each fire a shell, that is, 200 ammunition, which is just 100 seconds.

Even Li Hanlin couldn't sit still, so he handed the squad chariot to Long Lin and got out of the car himself.

When Li Hanlin opened the system panel, he had to intervene in the sentry gun, and closed it every second and then opened it every two or three seconds.

On the one hand, it is to save bullets for the sentry cannons, and on the other hand, it is to recondensate the zombies that appear in a neutral position and maximize the damage.

But this also made the zombies continue to advance, crossing a 100-meter-long natural barrier, 90-meter-80-meter-long. Finally, when the zombies arrived near 80-meter-long, Linglong arrived.

Because there was no communication tool, Li Hanlin didn't call Linglong for support. Fortunately, she was smart too. After hearing the gunshots, she rushed over from the machine gun turret. Some of them were wiped out on the way, and from other buildings, zombies attracted by the gunshots.

With Linglong's joining, Li Hanlin's pressure was greatly relieved.

At this time, machine gun sounded from behind, but the Nightingale, who was also awakened, entered the machine gun turret and manually controlled the machine gun inside.

There was no way. Even if there were zombies behind, Li Hanlin would not dare to activate the machine gun turret. Although this thing was automatic, he knew which one it hit first. If the only grenade was fired, Li Hanlin would cry to death.

At 70 meters, Longlin pressed the launch button. Li Hanlin did not want the zombies to have the chance to destroy the city wall, so he specifically instructed Longlin to take the initiative to fire when the zombies approached, and there was no need to save ammunition.

The whistling missile roared down again before it could rise to the sky, and exploded into the zombie group with a bang.

The missile is gone, and there is still a chance to replenish it in the future. If the wall is broken through, they will not be sure to block the giant dogs.

In fact, even so, Li Hanlin had no confidence. After all, these giant dogs were already so high, and the shortest part of the wall was only more than 1.5 meters, and he could easily flip over them, let alone those giant dogs with strong movement ability.

Therefore, Li Hanlin spent a huge amount of money early on, investing all the materials he had recovered the corpse and opened the treasure chest. Now he has less than 300 units of materials left.

This huge amount of money was used by Li Hanlin on the upgrade wall. One unit of materials was 200 units, and ten units were 2,000, which took a total of ten minutes.

The wall takes ten minutes to upgrade, and the machine gun bunker takes fifteen minutes to complete the layout. Li Hanlin felt that the second was like a year for the first time.

The distance between zombies is only 50 meters. Although the number has been reduced a lot, it is still very threatening, with at least 7,800 numbers.

There were only 60 shells left for the sentry cannon, and several missiles were shot out, but the fastest wall was still five minutes away.

"Bang, bang, bang, bang"

Li Hanlin has done everything he can do, and the rest of the time is left to fate, but he has also taken up his weapons and won more hope for victory.

Anyway, it really doesn't work. Everyone hid in the machine gun turret and probably survived. I just don't know if these zombies will destroy their buildings.

At 40 meters, 30 meters, and 20 meters, Li Hanlin began to throw grenades, and his strength had almost doubled and he could throw every grenade far.

In the last ten meters, the whistle cannon was activated, and the remaining shells were shot out in the whistle, and the front row zombies were cleaned up.
Chapter completed!
