Lu Yu smiled bitterly: "It's just that the Zerg that invaded our world is far less powerful than the top-level Zerg."

"If the top Zerg that can carry out interstellar wandering is a third-level civilization, then this Zerg at the bottom of the sea is only a first-level civilization."

"Although it is only level 1, it is still extremely aggressive, and if left unchecked, it will cause a catastrophe sooner or later."

“……”

Lu Yu explained, Pei Junfeng took out the film and television data illustrations.

After a long time, Marshal Lin Jun figured out what the Zerg was.

"Such an aggressive race, we must eradicate them!" Marshal Lin Jun said coldly: "I'm going to mobilize the South China Sea Fleet and the Yellow Sea Fleet to carry out a carpet deep-sea bombardment of the waters of Kyushu!"

"Good marshal!" Lu Yu said solemnly: "I will personally go to the coastal city to arrange the defense line!"

With the national disaster at hand, Lu Yu could only let go of the matter of Song Yi and Kunlun Mountain first.

Seven days later, Lu Yu arrived on the east coast with the Peerless Sword God Chu Yunzhong and the Kunlun Sword Immortal Pei Junfeng.

Subsequently, millions of tons of steel, stone, concrete and other materials were transported to the East Coast.

"This coastline is 580 kilometers long, and it must be defended in its entirety!"

In the Eastern Naval Region, Lu Yu said to the officers of the Eastern Naval Region: "A super Great Wall must be cast, with a height of 50 meters and a thickness of 3 meters, and all the perimeter of the city wall is made of stainless steel!"

"Also, mobilize half of the heavy firepower of the Eastern Naval Region to be stationed on the city wall, and mobilize at least 500,000 people from the Eastern Naval Region to be stationed here."

Since those 20 million recruits were assigned to the 18 major military regions of the country, the standing strength of each military region has reached more than 1 million!

"Okay general."

The deputy commander of the Eastern Naval Region nodded, and then conveyed Lu Yu's order to the regimental headquarters.

The Ministry of Architecture in the East China Sea region was also fully involved, mobilizing at least 300,000 workers to build the Great Wall on the east coast.

It is not only the East China Sea region that has begun to fully mobilize, but also nearby regions and military districts are moving resources and troops to this side.

In less than two days, the East China Sea region has stationed as many as 3 million troops, 10,000 tanks, 5,000 warplanes, and more than 1,000 new energy shaped guns newly developed by the Ministry of Scientific Research.

In the entire East Coast region, a strong barrier has been initially formed!

And the entire East China Sea area has been surrounded by the atmosphere of mountain rain and wind full of buildings.

Patrol soldiers can be seen everywhere in the streets and alleys, and ordinary people can see soldiers everywhere as soon as they go out.

For this situation, the common people are naturally afraid and confused.

"The military headquarters of the East China Sea region announced the latest notice: in order to prevent marine life in the East China Sea, the Yellow Sea, the Bohai Sea and the South China Sea, the East Coast Defense Line is specially organized, and all people should not go out if they have nothing to do."

Immediately after that, a curfew was directly declared in the East China Sea.

Although the common people did not understand why the military department should be wary of marine life, they still chose to follow the arrangement of the military department.

In the entire Tokai region, thirteen cities, as long as it is nine o'clock in the evening, the streets are empty.

All shops are forced to close before 9 p.m., leaving only essential places such as pharmacies, supermarkets, and hospitals open.

Then the common people who have nothing to do come home, and one by one the idle eggs hurt, and they are all kinds of moths.

It's all drizzle to brush short videos, and the kind of people who shoot short videos with their families are the big guys.

After filming, it's time to go to bed and sleep, and it's time to play games and games.

Anyway, during this time, the number of pregnancies has increased considerably.

……

"Hurry up, according to General Lu's order, the foundation of this defense line must be completed today!"

"Where's the stone team! And a bunch of braggarts over there, all of them moved for me, and the foundation must be laid today! ”

"Damn, that turtle son took my cigarette away!"

"Can you hurry up, this foundation is still short of three square concrete, hurry up and fill it in!"

"Damn, 100,000 tons of cement, is this going to tire our three teams to death!"

"Don't rub it off, cement on cement, stone on stone, and steel bars, hurry up!"

“……”

The thousand-mile defense line on the east coast was densely packed with workers and soldiers.

In front of them was the blue sea, and behind them were mountains of building materials.

The 300,000 workers were divided into 3,000 teams and scattered evenly over the thousand-mile line of defense.

On average, there is a worker every five meters.

With such a large scale, the scene was naturally extremely chaotic, but fortunately, there was an army supervisor, and there was no big mess.

Lu Yu walked to the defensive line, slowly walked to the sea, and looked at the blue sea carefully.

"Lu Yu, if there really are Zerg, then we should kill their mother worm!"

After Pei Junfeng finished speaking, he poked Chu Yunzhong, who was always silent, "Cold-faced hero, do you know the Zerg, it's the kind of ...... in the movie?"

Chu Yunzhong silently pushed away Pei Junfeng's chatter and walked to Lu Yu's side.

"Is the end of the world really coming?" He asked.

Lu Yu looked at the sea and nodded: "It will come, and it is very fierce, no one can hide from it."

"Lu Yu, you wouldn't still be thinking about Kunlun Mountain, would you?" Pei Junfeng suddenly interjected.

Lu Yu turned around and smiled, shook his head and said, "Don't talk about this, let's go, the diving fleet is already here."

Not far away, at the naval base of the Eastern Naval District, three diving fleets have already been assembled.

The three submarines have a total of 54 nuclear submarines and 20 heavy fire submarines, and are ready to carry out a sweeping operation in the four seas.

This is also organized according to Lu Yu's intentions, he wants to sweep away the Zerg in the four seas first.

At this time, the Zerg did not develop and were easy to clean.

"Let's go."

Entering the command submarine, Lu Yu and a group of naval officers and soldiers got to know each other briefly.

The three diving fleets then slowly descended into the ocean.

The ocean is black, and the deeper you go, the darker it gets.

This is because the sun's rays do not reach the depths of the ocean at all.

"Turn on the microwave cruise!"

"Turn on the bioelectric radar!"

"Turn on the command center satellite!"

"Turn on the sonic scanner!"

“……”

In the dark depths of the sea, the only thing that can be used as the ears of a submarine is these high-tech devices.

Lu Yu stood in the submarine command room, looking at the sonic scanner and bioelectric radar, he couldn't help frowning.

"This sea area is actually ...... Don't have a single live fish? ”

On the infrared sound wave screen, not a single living creature signal appears.

Could it be that this sea is empty?

"The current diving depth has reached 580 meters, and there is still not a single sea life."

The abnormal situation under the sea made Lu Yu's heart more and more uneasy.

At the same time, his speculation is getting closer and closer to the truth.

"Buzz...... Buzz ......"

Suddenly, the sonic cruise system emitted a screeching siren.

"General, General, there is a large-scale unknown creature!"
