"Bang...bang...bang...bang...bang...bang..."

The continuous impact woke Linglong and the others who were sleeping soundly. They turned over and got up vigilantly.

Even when they fell asleep, they were still dressed during the day, and these clothes were part of their arms, which were different from ordinary clothes.

Fortunately, at this time, the big bird in the sky had already landed on the ground. If Linglong and the others were still in the sky, Li Hanlin and the others would not be able to escape.

Li Hanlin quickly raised a finger to his mouth, signaling them not to make any noise.

Fortunately, they are not ordinary people. The first thing they do when they get up is to take out their weapons to prepare for battle. If it were Li Hanlin who was awakened, they would probably have screamed.

While the night vision was still there, Li Hanlin patted Nightingale's shoulder and signaled to go to the window to observe.

Nightingale frowned, unable to resist the command from the commander, but she did not make way out of the way, but crawled to the window to observe the situation first.

After confirming that it was safe, Nightingale signaled Li Hanlin.

However, Li Hanlin ran to the window and saw that the arsenal he built was already broken under the building.

One after another, big birds broke through the walls, doors and windows, and rushed into the arsenal where he was producing.

Even through the glass, he could hear the whistling sounds in the arsenal.

After a while, there was no movement in the arsenal, and the big bird that hit the inside flew away from nowhere again.

Li Hanlin looked at it again and found that the system interface showed that the arsenal had suspended production due to failure.

Fortunately, there are no living people in the arsenal, only automatic machines.

But it is also the noise and light generated by these machines that attract these big birds in the sky.

Li Hanlin must be grateful that the arsenal was hit by a disaster for him. The first-level tempered glass of the arsenal was vulnerable to these zombie-formed birds.

Even with the third-level diamond glass, so many zombies and birds, it may not last long.

Although these ghost birds have few feathers left, they can still fly. Not only can they fly, but their speed is probably faster than when they were alive.

Needless to say, the power is also the terrifying scream, which is probably not much inferior to the screaming banshee.

The most important thing is that these ghost things can fly, and even the walls can't stop them.

Nightingale observed by the window for a long time, but the ghost birds passed directly from the other end of the arsenal. No matter how good her eyesight was, she could not penetrate the walls and could not see these things.

Li Hanlin really wanted to turn on the radar, but the arsenal's previous lessons are still there. Who knows whether these things have flew far away? Don't just turn on the radar, these ghost things flew back.

If you count it carefully, there is only one of our own equipment that can be used against the air. One-third of the missile has been used up, and the remaining ones are probably only about ten of them will be killed.

After looking at the system interface, the remaining 1,400 materials were found. Li Hanlin was confused for a moment whether to build a Gate machine gun or an anti-aircraft gun.

The Gate cannon can face air and ground, and the anti-aircraft cannon can only face air, but the shells are flowering shells, which not only shoot farther than the Gate cannon, but can also cause group damage.

The only disadvantage is that the anti-aircraft artillery can only be installed at a high place, with the muzzle facing upwards, and there must be no obstruction around it.

In other words, anti-aircraft artillery has no ability to attack ground.

As for Patriot missiles, haha, this one can both kill air and face the ground, and also has an automatic tracking function. As long as it is not as fast as the missile, it will basically not be able to escape.

However, the price is too expensive and the ammunition reserves are small. Li Hanlin cannot replenish these ammunitions now, so he can only ignore them for the time being.

"Commander, why don't I go out and have a look?" Nightingale said with a frown.

If these ghost birds don’t leave, everyone will be unable to feel at ease, not to mention that the ammunition that Li Hanlin has reserved for tomorrow’s day has not been produced yet.

However, Li Hanlin also frowned. He did not dare to do anything if the zombie birds did not leave, or even left from a distance.

The arsenal has been damaged and is waiting for him to repair it.

Maintenance is simple, and there is a maintenance function in the building system. Only materials are required to support it. All system buildings can turn on the maintenance mode.

But whether the maintenance will shine and sound, Li Hanlin, who has never started it, can't guarantee it.

Therefore, if the ghost bird does not leave, he will feel at ease.

But to be honest, Nightingale's strength is probably not as good as him now, so he is really worried that Nightingale will go out alone.

Fortunately, he didn't have to make things difficult. Almost as soon as the Nightingale's words fell, the dragon scales woke up said:

"I'll go, my eyesight is not bad. After I go out, Sister Nightingale will add me a night vision ability."

Although the Dragon Scale level has not been much upgraded, she is a melee profession and is agile. Even if Li Hanlin's agility attribute exceeds Dragon Scale, she is probably far worse than her, not to mention now.

"It's good, so be careful with Dragon Scale and don't make any noise."

Li Hanlin made the final decision, and Dragon Scale did not disappoint everyone's expectations and disappeared in front of everyone almost without any sound.

At that moment just now, Li Hanlin noticed that the boots under Long Lin's feet directly merged into her body, obviously putting away the arms on her body.

After about five minutes, the dragon scales came back quietly.

The Nightingale, who was promoted to level 2, has increased her mental power a lot. Li Hanlin and Long Lin have almost nearly ten minutes of night vision, and are still in good condition.

"I just climbed onto the roof, and most of the zombie birds should have flew away."

"Most of them? What does it mean?" Li Hanlin asked immediately.

Long Lin knew that Li Hanlin would ask, and replied: "Where I could see, I only found one, and flew into the community, and seemed to be attracted by the people in the community.

Then, that person is probably in danger."

Long Lin hesitated in the end, but she did see that maybe the family heard the movement outside and wanted to observe it, so she opened the curtain a little.

However, it was the corner that was opened, a trace of light was revealed, and the zombie bird was discovered by the unknown reason.

Li Hanlin was very angry. He had not finished the rescue mission, but the rescue target was missing.

Moreover, although they are not from the same world, they are all human beings. When Li Hanlin heard such news, he felt sorry for him.

"Dragon scales, can the target be observed?"

Long Lin nodded with certainty and said, "Yes, there are several people in that family. The zombie bird did not kill everyone, but was eating slowly."

"Didn't kill everyone, eat slowly?" Li Hanlin was very confused.

However, Dragon Scale nodded affirmatively again.
