Under the scorching sun, people did not rest outside the walls of Zhongzhou City and were in full swing.

The roar of machinery makes people excited.

More than one million people are in a mentality, more than one million zombies assist, tens of thousands of machinery, tens of thousands of trucks... are indeed extremely spectacular.

Especially looking down from the sky, it makes people feel even more shocking.

At this time, Lu Chuan was sitting on the back of the corpse dragon, staying with Aphrola on it, looking at the busy construction site, and feeling very accomplished.

Aphrola had a look of admiration on his face. In Moscow, the pope did not have this appeal. He could unconditionally execute it with a command. However, Lu Chuan, his own man, had this kind of power.

If the large construction site is divided into sections, these people and zombies are stretched out, almost surrounding Zhongzhou City, which is very spectacular.

"It's still a little slower."

The progress below was actually very fast, but Lu Chuan still felt dissatisfied.

In terms of this kind of construction, this kind of construction is already the limit, and Lu Chuan has no good idea.

Every day, Lu Chuan feels the urgency of time. It seems that this offensive and defensive battle will change time due to his own unlocking, but this change will definitely not last too long.

Construction still needs to be accelerated.

Lu Chuan touched his chin, thinking about how to speed up. For example, mobilizing more zombies to join and mobilizing more survivors to be involved in the excavation?

The current survivors can already draw the maximum limit. If there are too many, it will affect other work. Whether it is the Ministry of Agriculture, the arsenal, etc., it requires a lot of personnel and material resources.

Soon, Lu Chuan's eyes fell on a zombie floating in the distance.

Dolphin?

The next moment, Lu Chuan's eyes lit up, and he was just laughing.

"Yes, why didn't I think of the dolphins and dragons?" Lu Chuan slapped his head. Maybe he had thought about this moat before, and he had to think about it as a circle.

In fact, Lu Chuan just wanted to prevent invisible zombies, like Shadow Blade and Ghost Guards from rushing forward. If there is a moat, it is impossible for them to approach Zhongzhou City at will.

This is the function, just enclosing it, and you don’t have to care whether the moat is round or square.

It's very troublesome to be round, but if it's square, it's simple.

What does it mean to spray the time and space light of the dolphin dragon? With the dolphin dragon in there, you can dig this moat in one day, and the rest is to lay cement for waterproofing.

"Yes, just do that." Lu Chuan smiled.

…………

The people who were digging the moat suddenly received orders and evacuated the area.

They were a little curious about what was the reason, so they started digging and stopped it. Many people were dissatisfied with this order from the superior. Isn’t this trouble?

However, this order was issued by the Supreme Command. No matter how unacceptable it is, it must be implemented.

Countless survivors evacuated and moved out of this area with machinery.

However, the order they received was to stay here, that is, at the foot of a wall that was up to 100 meters high, and not to be allowed to run around, nor to leave the area within the wall.

Everyone was talking about what was going on.

Soon, they noticed that there were a large number of dolphin dragons in the sky, a kind of round zombie. No one knew what kind of zombie this was, because this was the first time many people saw this type of zombie.

They have hardly ever contacted this kind of zombie.

They can always be seen above the settlement, but this kind of zombie gives people the feeling that it is completely harmless, like a balloon floating in the sky.

Occasionally, some people are close to the ground, and they look like pufferfish, which also makes many people think that it is more like an ornamental zombie.

This time, Lu Chuan is commanded by the commander zombies. In this way, commanding zombies will gain memories. If this method is needed next time, Lu Chuan does not need to take action personally.

The size of a puffer fish is usually about 50 meters. Once it enters a combat state, it will become a super monster of 200 meters, which is smaller than a crocodile and dragon corpse, but it is also very amazing.

The beam of light it ejects will diffuse into a circular light with a diameter of about 200 meters.

Lu Chuan took Aphrola and waited for the evacuation of everyone below in the sky.

After confirming that everyone had evacuated in a certain section, Lu Chuan commanded a dolphin dragon to descend from the sky and land on the ground.

This is a moat section that has just been dug up and can be accommodated by the dolphin dragon.

"Enter into combat form."

As Lu Chuan's instructions were issued, the dolphin suddenly expanded, and in the surprised eyes of countless survivors, it turned into a nearly circular super giant monster with a diameter of 200 meters.

The appearance of the dolphin dragon really makes people unable to associate it with zombies.

What is the concept of 200 meters? This will appear like a mountain, which really shocked everyone's eyes and made them a little difficult to accept.

This kind of dolphin dragon, which usually believes that humans and animals are harmless, has such a terrifying change.

After entering the combat form, Lu Chuan began to adjust the direction of the dolphin dragon.

This is very simple, and after a few instructions, it is completed.

"Xiaosi, is it accurate?"

Lu Chuan contacted the Smart Xiaosi. It controlled a large number of satellites, could accurately calculate the direction deviation of the dolphin dragon, etc., and then generated virtual indicators in front of Lu Chuan.

As long as these virtual indicators are aligned, it means there is no problem with accuracy.

"Boss, it's OK." Xiaoshi responded.

"injection."

After Lu Chuan confirmed that the direction position was not deviated, he immediately issued an order.

This dolphin dragon burst out immediately after Lu Chuan's instructions. The space-time light that ejected from its mouth, formed by the beam of light formed by the space-time light blasted forward.

The time and space light that can destroy all the world, gasify all the soil blocking in front of you, and blast out a trench 200 meters wide and nearly ten kilometers long on the ground.

The terrifying space-time light, the violent energy fluctuations when it appears, bringing the impact force that makes the surroundings feel like they have experienced storms. Countless survivors opened their mouths wide and looked at the dazzling light.

The light flashed in a flash and disappeared in the blink of an eye, but the destructive power it brought was so huge that it made them all feel terrified.

Who would have thought that this dolphin dragon could actually emit such a terrifying blow?

Looking at this huge groove that is ten kilometers long and 200 meters wide, everyone opened their mouths and showed an incredible look.

They thought they needed to use huge power to moats, but now it seems as simple as one plus one equals two, and there is no difficulty.

A dolphin dragon completed this attack, and it fell into the weak stage, then flew into the sky and floated.

The next dolphin dragon descended to the end of the groove again.

Just a few minutes later, a terrifying energy beam appeared again, and the entire air brought violent fluctuations, which made people suffocate, as if all the oxygen here had been absorbed.

Another ten-kilometer-long groove appeared, adding up in less than ten minutes.

"According to this progress, I worked for half a day and I dug it out."

"The boss is really a genius, you can imagine this method."

"The most powerful one is this dolphin dragon. Who would have thought that it would be so domineering and perverted?"

The survivors were stunned and stared at the grooves that appeared in the second paragraph, talking one by one. For them, today it was really an eye-opener.

Of course, some people are still full of sorrow.

This is a zombie. If you encounter it in the future, how can you escape? This kind of energy beam, as long as it is swept, there is no way out.

The function of the dolphin dragon that appears here is rotation.

After a dolphin was shot, it took off to rest. It was the next one. Lu Chuan had a large number of dolphins in his hand, so there was no need to worry about not enough.

The three dolphin dragons are a 30-kilometer-long line. According to this progress, they can be dug today and let them start laying cement for waterproofing tomorrow.

Compared to these violent jobs, there is no skill in laying cement and waterproofing, and it requires the cooperation of all parties to complete it.

A ten-kilometer groove is a few minutes long, and these grooves are as smooth as mirrors, almost formed in one piece.

The reason why waterproofing is still needed is that at ultra-high temperatures, some places are leaking and need to be repaired. Otherwise, the glass layer formed by ultra-high temperatures no longer needs to be laid with any cement.

Three hours later, a huge square moat was excavated.

This speed has shocked many people's attention.

Judging from the terrible energy beam, if it is used to build highways or railways, just to build channels, this efficiency may be increased by more than ten times or a hundred times. When encountering mountains, it will be sprayed directly and then penetrated. There is no such thing as digging for a few years or ten years.

The moment the dolphin dragon retreated, I don’t know how many people came over and watched the huge groove that was five meters deep, 200 meters wide and more than 200 kilometers long.

The crystals at ultra-high temperatures make it almost as smooth as a mirror.

In most areas, there is no need to lay cement, just some partial waterproofing.

In this way, the time and material resources saved will be huge. There is no need to mobilize millions of survivors, only 100,000 can complete the tasks assigned by Lu Chuan in a short period of time.

"Moat, finished."

Lu Chuan smiled on his face. The role of the moat was actually mainly to defend the shadow blade and the ghost guards sneak up. They were invisible and it was difficult to find them.

But with this moat, if they want to come over, they need to cross the moat. The rivers will contain corrosive liquids. If they dare to wader, they will be ready to enjoy the meal they have prepared for them.

Of course, Lu Chuan did not rule out that the other party used the corpse dragon as a transport body and then airdropped the ghost guards.

This move is very difficult to deal with. Once the opponent invests enough ghost guards in the city, there will definitely be ghost guards that can approach the biochemical factory. If you don’t pay attention, it will cause your own defense failure.
