More than a day is not long, but it is not short.

The devil's plane could not give Li Yunlong's station more opportunities to prepare.

Obviously, these devils' planes are here to test the reality of the station.

Every time the devil's reconnaissance plane came over, Yang Shishi and Yang Erxiao would shoot at the devil's reconnaissance plane in the sky.

There are only ten anti-aircraft guns on the base, and according to Yang Shishi, there are now at least six anti-aircraft guns, which have been exposed to the sight of the devil's reconnaissance plane.

This also means that the bombardment of the devils will begin.

"Stone, let the brothers get ready, it is estimated that the devil will launch an air attack today, and then how can the devil's shells be stopped, so as not to fall on the side of the R&D base."

"Regiment commander, since the imp's reconnaissance plane has made several trips, will it have discovered the position of our anti-aircraft guns?"

Yang Shishi asked a little worriedly.

Li Yunlong grinned his teeth, "This is for sure, the little devil plane came over just to find out our reality, and even the situation when Lao Tzu led the team back, these guys have already noticed it." ”

Li Yunlong did not maliciously guess whether the little devil deliberately waited for him to come back before launching the bombing operation.

After all, Li Yunlong has killed a lot of devils, and now the name Li Yunlong is basically a black hole in the Japanese military.

It can be said that if the existence of Li Yunlong is erased, there will be a lot of uncertainties in the plan of the Japanese State to attack Huaxia.

The efficiency of the devil was very high, and as soon as the time reached noon, the soldiers brought back by Li Yunlong had just taken a short break and were having lunch, when the roar of the bombers came from afar.

"Alert, alert!"

With Li Yunlong's order, everyone took action.

Yang Shishi is still in charge of the anti-aircraft guns at the dock position, and as the backbone of the highest level of shooting, Yang Shishi must guard the first line of defense.

Piles of anti-aircraft shells, piled up in front of the anti-aircraft guns on the dock.

Since the arrival of this batch of anti-aircraft guns in the Primordial Island, the research and development units began to study the imitation of anti-aircraft guns and shells.

Now the R&D base has produced a large number of anti-aircraft artillery shells, so Li Yunlong's troops are most indispensable for anti-aircraft artillery shells.

It's just that anti-aircraft guns are still at a critical juncture in the development of anti-aircraft guns, and according to foreign experts, it is possible to solve the problem of tracking and positioning anti-aircraft guns at any time, and once this problem is solved, those anti-aircraft guns that have completed the assembly of components can be put into combat use immediately.

In this case, Li Yunlong can only wait, and he can't be in a hurry.

However, Li Yunlong only left four anti-aircraft guns at the base, and with his own guard, he could definitely guarantee that the devil's bombers would be taken down.

Li Yunlong is still very confident in this.

I carefully counted the bombers flying in the air, and there were twelve of them.

The devil's bomber, when it was about to approach the dock, the anti-aircraft gun controlled by Yang Shishi immediately opened fire.

Rumble!

A white smoke rose into the air, and the devil bomber that was hit was not very dazzling because of the daytime.

I saw that the plane was rising and fell into the sea near the pier.

Li Yunlong, hey, yes, this guy has figured out the doorway of the anti-aircraft gun, and it seems that this first level is formed.

With the success of Yang Shi's first counterattack, it gave all the soldiers great encouragement.

"Brothers, Brother Shi knocked down the devil's plane!"

"Commander, we also want to participate in the war, so that the devil will not drop a bomb on our heads."

Before the shout could be heard, a bomb had been dropped from the bombers hovering over Primorsky City.

I don't know where it was in the city, but it was blown up by this bomb, and when you look at it from the base, you can only see a puff of smoke and dust rising above the city walls.

Li Yunlong snorted, "Grandma, the little devil is dying, if Lao Tzu doesn't beat you all down, he won't believe it." ”

Li Yunlong didn't do it himself, but just let a few soldiers around him start to learn to use anti-aircraft guns.

"Adjust the muzzle, estimate the flight trajectory of the devil bomber, and follow the devil's plane to move!"

"You kid listen well, you have to learn to predict the trajectory of the devil bomber's flight in advance, understand?"

"Why are you so stupid!"

"That's right, that's the direction, fire!"

As Li Yunlong ordered the cannon to fire, another shell hit the air.

A bomber flying towards the R&D base was stopped in the air by this shell.

When the shell hit the devil's fighter, thick black smoke suddenly rose up, and the devil's plane, whirling down, landed outside the city wall less than a mile away from the R&D base, igniting a thick flame.

Li Yunlong took a deep breath.

Fortunately, this shot was fired in time, and one minute later, the plane could fly over the R&D base, and at that time, any bomb could blow up the facilities in the base.

Li Yunlong will never allow the little devil's bomber to wreak havoc in the R&D base he has worked so hard to build, and not even a single bomb can fall here.

With Li Yunlong's personal guidance, the efficiency and hit rate of several fighters were greatly improved, and in less than half an hour, more than a dozen shells were fired.

After being shot down three times in a row, the devil's fighter has also learned a lot smarter, and every time he approaches the base, he will constantly do tricks to change the direction of flight.

This did avoid being hit by the anti-aircraft guns below, but again, the accuracy of their bombs was greatly reduced.

After a while, more than a dozen bombs were dropped, and none of them hit important facilities.

Until about three o'clock in the afternoon, the devil's bombers began to retreat one after another, and the anti-aircraft gun guarded by Li Yunlong had been used up.

The repeated firing of too high a frequency had already burned the chamber of the anti-aircraft gun, and a basin of water poured on it could be sublimated into a cloud of water vapor in an instant.

Even Li Yunlong sensed that the accuracy of this anti-aircraft gun was no longer good.

In just a dozen cannons, an anti-aircraft gun was scrapped.

This kind of cost makes Li Yunlong a little entangled.

Grandma Zhente, these little devils are still very difficult, Li Yunlong scolded in his heart, and then looked at the air.

The devil's fighter had flown away and disappeared, and Yang Shi hurriedly ran over.

"Regiment commander, two anti-aircraft guns over there have been scrapped!"

Li Yunlong frowned, "Ship it back immediately, ask a few experts to repair it, this air raid operation of the devils and devils this afternoon did not succeed, and it will definitely come again in the evening." ”

A total of three anti-aircraft guns, all of which were transported to the repair yard of the R&D base, and before Li Yunlong could go over to invite a few experts, Wolf took Bach and greeted him with a bright smile.
