After seeing the true power of the lightning storm, Ling Feng secretly regretted it in his heart, thinking that he should have exchanged more in the arsenal just now.

There are only five lightning storms now, and in case a large-scale alien spacecraft invades their defense zone tonight, it is estimated that these five lightning storms and nineteen A5 energy boxes will be difficult to cope with the enemy's attack.

Thinking of this, he returned to the first line of defense again, and deployed all the 100,000 main battle tanks and more than 10,000 large artillery pieces that he had just obtained from the special flop.

After he was done, he teleported out all the one hundred and thirty-five golden mechas, and after handing them over to the one hundred and thirty-five ninth-generation robots, he ordered them to control these golden mechas, patrol around the entire military defense area, and use the laser weapons of the golden mecha to attack and intercept the enemy as soon as they found any abnormal movements.

If the enemy is outnumbered, retreat and try to keep these golden mechs from being damaged.

After hearing the order, a group of ninth-generation robots responded one after another.

After explaining all the precautions, it was already half past three in the morning.

At this time, Ling Feng was ready to return to the underground shelter to rest.

After returning to the underground shelter, Ling Feng couldn't sleep at all, because he was always worried about the safety of the defense line, and he didn't dare to close his eyes.

I stayed up anxiously until dawn, and at this time, according to the reports from all the monitoring bases, it was said that no alien invaders had appeared for the time being. His heart slowly settled down.

As long as no alien invaders attack their defensive bases before dawn, they will basically not appear for the entire day.

Now, he had to hurry up and get some rest, because night was the crazy time for those alien invaders to attack.

Soon, the day passed, and night fell again.

After Ling Feng and his brothers had dinner. He hurriedly drove the golden mecha out of the underground shelter. Came to the first line of defense.

Since the arrival of Advent Day on December 17th, on the night of December 17th and 18th, there have been alien invaders attacking their defense bases, and the number of alien invaders. There are more and more of them.

If nothing else. Tonight. There will also be alien invaders coming, and most likely, there will be a number of them. It will be more than the previous days.

Thinking of this, Ling Feng had an extremely headache, thinking to himself, tonight is estimated to be a very difficult night.

But in any case, there are still tens of thousands of fighters and bombers stored in its five airfields, and there are more than 10,000 Apache helicopter gunships.

With so much arms and equipment, it should be enough to deal with tonight's attack.

As long as he survives tonight, even if he uses all the weapons and equipment, he doesn't care.

Because, after twelve o'clock in the morning, he will enter the infinite arsenal again, and exchange the remaining 3.2 billion honor achievement points for Lightning Storm and A5 energy box.

When the time comes, outside the first line of defense, hundreds of lightning storms will be deployed to ensure that those alien invaders will die as many as they come.

Before I knew it, it was already half past eleven in the evening.

Tonight's situation is a bit unusual, because until now, I have not received any news of an alien spaceship.

This made him nervous, but secretly a little lucky.

Because, in half an hour, it will be a new day, and when the time comes, it will be time for him to enter the arsenal and exchange lightning storms on a large scale.

Deploying the lightning storm outside the defensive line earlier, then his losses in the future will be much lower, at least, he doesn't have to constantly send fighter jets to hit those alien ships with perverted defenses to the ground.

The night before yesterday against sixteen alien ships, he had lost four hundred fighters.

Last night, in order to knock the 135 alien spacecraft to the ground, he dispatched 2,500 fighter planes, all of which had never returned.

If those alien invaders lead more alien spaceships to attack tonight, it is estimated that all the fighters and helicopter gunships in his reserve will have to be exhausted.

Soon, half an hour passed.

Until now, no alien invaders have come to attack the Nine Stones Mountain defense base.

Just as the stopwatch of the clock jumped to midnight, a new day arrived - December 20th.

In an instant, Ling Feng's figure disappeared out of thin air.

After entering the Infinite Arsenal, Ling Feng's purpose this time was very clear, that is, he came to exchange for Lightning Storm and A5 Energy Box.

Coming to the giant display screen, Ling Feng instructed the system to open the equipment exchange shop and enter the exchange area of Lightning Storm.

Before exchanging equipment, Ling Feng also deliberately checked his remaining honor achievement points, and found that the remaining honor achievement points were just a little more than 3.23 billion yuan.

These honor points, but he has accumulated them for a few months, and today he has to use them all, and he seems to be a little reluctant.

With a deep sigh, Ling Feng spent two billion honor achievement points to exchange for one hundred lightning storm launch bases, and another one hundred billion honor achievement points to exchange for one thousand two hundred A5 energy boxes.

After a period of frantic profligacy, Ling Feng's remaining honor achievement points were only more than 30 million.

The remaining more than 30 million yuan is for emergency use when Ling Feng keeps it at a critical time, and he will not use it for the time being.

Ay! Honor achievement points, this thing consumes quickly, and when it accumulates, it's really sleepy.

However, with these one hundred and five lightning storms and one thousand two hundred A5 energy boxes, the overall defense capability of the Jiushi Mountain Military Defense Base has been improved by at least several grades.

When he was done, Ling Feng quickly withdrew from the Infinite Arsenal.

Returning to the defensive line, Ling Feng immediately led 30,000 robots to follow him to arrange these lightning storms.

One hundred lightning storm launch bases. All were deployed by him on the periphery of the first line of defense.

To the southeast of the defensive line, twenty lightning storms were deployed, because the south and east were coastal areas, and generally there would not be too many alien spacecraft attacking across the sea.

As for the north and west sides of the defensive line, that was the most important part of the defense.

So, in these two areas, he deployed thirty lightning storms each.

To know, the southwest direction of the defensive line. There are countries such as India, Myanmar, Thailand, Vietnam, etc. It is estimated that it will not be long before a large number of alien ships will come along the southwest direction to attack his defensive base.

To the north of the defensive line is Jiangbei, where the federal government has retreated.

The alien invaders who came to attack Ling Feng's defense base these days. All of them came from the north side of the river.

Presently. There were only more than 100 alien spaceships coming over to Jiangbei. It is estimated that the further back you go, there will be more and more alien fleets that will come to attack the Jiushi Mountain Defense Area.

Once those alien invaders. After conquering all the countries and cities in the world, the last thing they jointly besieged was definitely the Jiushi Mountain Military Defense Area where Ling Feng was located.

At that time, it will be the beginning of his arduous struggle.

Compared to the battles of yesterday and the day before yesterday, all this is just an appetizer, and the real bloody battle is estimated to come soon!

Ling Feng looked at the pitch-black night sky and sighed secretly, "I hope that the lightning storm that I spent billions of honor achievement points to exchange can block the attacks of all enemies!" ”

December 20th, 3 a.m.

One hundred and five Lightning Storm launch bases, one thousand two hundred and nineteen A5 energy cartridges, all deployed and prepared.

From now on, as long as an alien spaceship comes to attack the Nine Stones Mountain Defense Zone, then Ling Feng can destroy all those alien invaders when they are less than a hundred kilometers away from the defense zone.

Because, a hundred kilometers is the nidal range of the lightning storm, and within the nilly range, everything will be destroyed, including those alien ships with perverted defense, and they will not escape the doom.

From last night to the early hours of this morning, more than a hundred golden mecha have been patrolling the entire Jiushi Mountain defense base, and Ling Feng has also been staying within the defense line, paying attention to the news coming from the monitoring base.

What made Ling Feng very strange was that until more than eight o'clock in the morning, no alien spacecraft came to attack their defense area.

This result does not bode well, and it is estimated that those alien invaders are brewing a huge attack.

As for when their attack would come, Ling Feng didn't know, but he wasn't particularly worried, after all, there were more than a hundred lightning storms deployed on the periphery of the entire defense zone, which could at least destroy several waves of enemy attacks.

A day passed, and the surroundings of the defense zone were calm as usual.

Ling Feng did not let his guard down, but ordered all the robots to monitor and patrol more closely.

Finally, at half past eight in the evening, the robots monitoring the base discovered an anomaly.

"Report to the sir, in the southwest of the defense area, there are two hundred and forty-seven alien spacecraft flying from the territory of India, and now they have entered the airspace of the south, according to their flight speed, they will enter the territory of Gandong Province in about two hours......"

"Report to the sir, a new situation has been discovered, five hundred alien spaceships have appeared in the sky over Jiangbei, and they have now crossed the south bank of the Hengjiang River and are rapidly flying towards Gandong Province, about an hour later......"

Hearing this, Ling Feng's heart was shocked, and he hurriedly ordered: "All robots obey the order, lock on to all abnormal targets, keep an eye on their movements, as long as they enter the blast storm's killing range, fire with all their might, and destroy them!" ”

"Yes, sir!" When the robots heard the command, they suddenly agreed.

At this time, Ling Feng quickly got dressed, and after saying hello to Chen Youyun and the others, he drove the golden mecha, left the underground shelter, and flew straight to the first line of defense.

Ling Feng knew that tonight, there would be a big battle.

Whether or not the more than 700 alien ships that came to invade can be destroyed depends on the power of these lightning storms. (To be continued......)
