After more than an hour, Lu Shan could clearly feel that the marine life within 30 kilometers from the land was rapidly decreasing.

And those marine creatures are migrating in groups, and...Most of these groups of marine creatures don’t move too far, just move to places tens of kilometers away, they will temporarily The ground stopped.

It can be seen from this phenomenon...Those migrating marine life groups obviously received the order, and then began to consciously withdraw from the nearby 30 kilometers of Sanbei Island.

It's just that...Even if the marine creatures have some intelligence, the concept of kilometers is definitely not as clear as human beings! Even... Without a measuring tool, in this vast ocean, even humans cannot find out exactly where the 30-kilometer distance is.

So... those marine creatures can only migrate as far as possible to some distant places, some migrate hundreds of kilometers away, and a few will migrate away from fifty to sixty kilometers.

Of course, there are also a very small number of marine creatures, and I don’t know whether they really don’t have a clear concept of distance, or they are simply commands passed from above the negative treatment of the group, anyway...not only did they not go as far as possible. Local migration, on the contrary... At most, the migration was less than ten kilometers away, and it had already stopped, and then what should be done, no longer paying attention to any orders.

Naturally, Lu Shan wouldn’t care about this... It’s better if there are some good marine growth groups, otherwise... If these marine creatures are really obedient, they will retreat tens of kilometers away obediently. After that, he has no excuses to go fishing, isn't that boring?

But seeing that the old turtles must have already implemented the agreement between the two parties, Lu Shan naturally has no trouble breaking the rules. If he continues to fish for seafood here, it will be too shameful for the old turtles!

If Old Turtle used this as an excuse and did something excessive when he turned around, Lu Shan would have nothing to say not!

As a result, Lu Shan decisively stopped his previous actions, and after the transport ships transported the last batch of seafood away, he flew in the air...went around in the waters near Whale Harbor, and waited. It was confirmed that most of the marine life had indeed exited the offshore area of ​​the land, and then turned around and returned to Whale Harbor City again.

The battle here has been fighting for several hours...In the beginning, those cruise ships also used sonar bomb tactics to attract a large number of zombies from several different directions, and then used the laser cannons on the cruise ship. Fan crazy fire.

The resident population of Jinggang City has reached more than 25 million. In addition, there are some migrants, at least several million.

And these people... after the catastrophe, almost all became zombies, only about two hundred thousand people escaped from the urban area and several camps were established around the city.

And in urban architecture, there are naturally some sporadic survivors...

But even if you exclude the two, then... in the super-large coastal city of Whale Harbor, the total number of zombies is nearly 30 million!

Even with ten cruise ships and 20,000 Chinese soldiers attacking the city, it still feels like a drop in the bucket.

Although sonar cannons and laser cannons are indeed very useful, after first using the sonar cannon to attract, and then a wave of laser cannon harvesting, after a few rounds... almost half of these 30 million zombies have been wiped out.

But... Even so, there are nearly 10 million zombies left! And this number of zombies is even larger than the population of some small cities before the catastrophe, so... I want to rely on the only 20,000 Chinese army on ten cruise ships, and I want to eliminate so many. The zombies are still idiotic.

Fortunately, Lu Shan had already considered this issue, knowing that the effect of sonar cannons would be greatly reduced in battles in such super-large cities.

After all, a district of this mega city may be larger than all the urban areas of a small city. The sonar bombs here were dropped on the outskirts of the city, not to mention that the zombies in the depths of the city may not be heard at all. Or even if they can hear it, it is difficult to arouse their interest.

Even if these zombies hear it, they will follow their instincts to greet the place where the sonar cannon exploded, but they ran from the city center to the outskirts, and they probably won’t be able to travel for a day...the cruise ships can’t always be there. Waiting there for them to arrive before harvesting the zombies gathered below?

Besides, even if the Huaxia Army in the cruise ship waited patiently, but... the zombies gathered before would not wait. If they were not attacked, they would all disperse after a while. ...It is equivalent to the previous ones also doing useless work.

Therefore, the method used to deal with small and medium-sized cities performing extraordinary work, in such a super-large city, is somewhat ineffective!

Unless... Lu Shan can give an order so that the Chinese Army no longer needs to deliberately protect the buildings in the city, and directly throw bombs everywhere in the city, and then gather a wave of zombies and use laser cannons to blast... If there are 30 million zombies in this city, even if there are 100 million... If you bomb it in this way, you will get all the zombies clean.

However, the destructiveness of the laser cannon is really too great... Once the laser cannon is allowed to let go of the attack in the urban area, that area of ​​the urban area can be completely turned into rubble in a short time.

But if you want to re-repair the previously demolished building when you look back... then I am afraid it will take at least a few years to repair it bit by bit!

How about destruction is always easier than construction?

And Lu Shan’s specially prepared countermeasures for such super-large cities... are the kind of armed robots Lu Jiang had previously produced in large quantities on the earth.

In fact, the production cost of this armed robot is not high, and its individual strength is also very limited, but it is definitely enough to deal with ordinary zombies!

As for the powerful giant zombies, there are naturally heavy firepower in the Chinese Army, as well as armored vehicles and tank soldiers to deal with.

Although the individual strength of those armed robots is not very strong, the weapons they are equipped with may not even break the defense of giant zombies, but they are extremely efficient against ordinary zombies.

When Lu Shan flew over the Whale Harbor City, I saw...In the downtown of Whale Harbor City, there were men in black suits walking between the buildings like ghosts, five fingers from time to time. The ground will emit one or several faint light beams. These light beams are as fast as lightning. They hit the foreheads of the zombies on both sides of the street, leaving a blood hole in the center of their foreheads. It will turn over and fall, and it will be difficult to get up again!
