Wave after wave of unsettled, the problem of the invasion of underground civilization has not yet been solved.

The underwater civilization that suddenly appeared at this critical moment struck a knife against human civilization, but human civilization was helpless against this situation.

It's not that there are no troops, but human beings belong to terrestrial civilizations, and the creatures of marine civilization can attack any human city along the long coastline at any time, but human civilization has no way to take the marine civilization hiding at the bottom of the sea!

Fight people in the water?

Not to mention that you can't beat it, as long as people drag you to the bottom of the sea and fight, they can suffocate you to death!

Not to mention the long coastline, which is simply impossible to defend, and don't forget that the whole world is surrounded by the sea!

In the face of the attack of maritime civilization, human civilization can only be passively beaten, not to mention that ships on the sea cannot enter the sea, and even submarines of all kinds dare not go into the water.

The surface ship was poked and leaked, and the human warriors on it could still flutter and struggle twice when they fell into the water, if the tin cans soaked in the water were poked and leaked, then they would sink directly to the bottom, right?

In desperation, the countries of human civilization had no choice but to set up a rapid reaction force and drop a large number of radar sonars in the coastal waters of coastal cities, and once they discovered a large-scale landing operation of maritime civilization, they would immediately snipe at it.

The only good thing is that just as it is difficult for humans to move on the ocean floor, it is equally difficult for the creatures of marine civilizations to move on land for long periods of time.

Therefore, except for the coastal cities that are threatened, the inland areas that are more than 100 kilometers deep inland are absolutely safe.

As a result, the economy of the coastal areas, which were far more prosperous than the interior, has suffered a severe setback, and a large number of coastal residents have fled in fear.

Compared with the underground civilization, which is suppressed underground and has basically no chance to show its head, the threat of marine civilization has caused great losses to human civilization.

Placing the "Frontline Command of Submarine Civilizations" at the Dragon Palace Base in the East China Sea deep at the bottom of the sea, in addition to launching a counterattack against the maritime civilization at close range, also plays the role of a decoy, hoping to attract the maritime civilization to attack here, rather than harassing those coastal cities.

But I don't know if the marine civilization knows the power of this undersea base, or if it thinks that there is no oil and water here.

Not to mention launching an attack on the front-line command of human civilization, there is no action to even send scouts to investigate, how can the human coalition not worry?

Countries around the world have already blocked coastal cities and stopped any marine fishing and coastal tourism industries, and the losses are heavy.

Even in order to ensure the safety of coastal cities, defensive walls began to be built along the coastline.

The original sun, sand, and bikini have been replaced by ugly gray cement walls, which look extremely depressed and gloomy.

After getting the news, in addition to opening the East China Sea Dragon Palace base for the human civilization alliance to be stationed, the two who went on an expedition deep underground did not rush back to the surface as soon as possible.

Because they had to suppress the crazy underground civilization first, and liberate the supernatural warfare power of human civilization from the war with the dreadsaurs.

Therefore, after releasing the restraints on the Scourge Legion, Second One ordered them to build a layer of "near-ground protection net" in the underground world.

In a large number of underground spaces that have been captured, a large number of undead legions have been stationed, like outposts, guarding the nodes of the ancient underground tunnel network.

If the dinosaurs of the underground civilization want to attack the surface, they must first uproot these undead strongholds, otherwise they will be endlessly harassed by the undead who are not afraid of death.

It is estimated that the dinosaur people also vomited blood from this batch of undead creatures that suddenly appeared.

The strength of the low-level undead is low, and the individual is very fragile, so the ability to attack the underground world is not enough.

However, they were stunned to rely on the characteristics of being full of quantity, fearless of death, and getting stronger and stronger, and dragged the attack of the lizardmen troops alive.

The intensity of the invasion of the underground civilization was suddenly reduced, allowing human civilization to breathe and mobilize troops to defend coastal cities.

The stalemate in the war with the underground civilization is a good thing for human civilization, but it also leaves hidden dangers, once the underground civilization is allowed to gain a firm foothold, it will be enough to drag human civilization into the quagmire of long-term war.

But what can Er Yi do, rely on him to destroy the underground civilization alone?

What does that do for his plan to advance to human civilization?

So he can only be a headache for his life, and he can control the situation first.

After suppressing the threat from the underground civilization to a small-scale and low-intensity level, the two of them terminated their plan to rush into the dinosaur lair in one go, and urgently returned to the Dragon Palace base in the East China Sea.

“...... At present, all the member countries of the World Federation have handed over the naval forces that can be mobilized in their hands to the command of the coalition forces, and the weapons and equipment that can be collected have also been assembled, but due to the impassability of the sea, they have all stayed on the defense lines within their respective territories for defense. ”

Commissioner Qin, the representative of the Huang Guofang who was appointed to be in charge of the Longgong base of the World Federation in the East China Sea and the management and coordination of the human alliance, introduced the current situation of all parties to Eryi, the seat of the Local Security Bureau, with a serious face.

In this regard, Eryi expressed his approval.

Although those surface ships are useless in the war against the civilization of the seas.

If you dare to sail, you will be sunk, and you can only huddle in the harbor of coastal cities or offshore to use as shore defense artillery.

However, this act has at least achieved the goal of promoting the unity of human civilization, and it seems that strong enough external pressure still has a certain effect.

As long as this model continues, I believe that one day human civilization will be able to abandon the distinction between countries and work together to fight against foreign enemies.

In order to enhance the voice of Huang Guo in the World Federation of Human Civilization Alliance.

Before he came back, Er Yi had secretly handed over the command of the Yanhuang team to Commissioner Qin temporarily.

It can be regarded as helping him support his waist in the human alliance, lest Lucia and America, the two old powers, secretly want to be the leading big brother.

In addition to the more than 100 people in the first phase of Yanhuang and more than 1,000 people in the second phase of Yanhuang, when they moved to the Dragon Palace base in the East China Sea, the Yanhuang team had already gathered more than 10,000 people in the third phase, so the Yanhuang Super War could be regarded as an official army.

In addition, the 100,000 followers of the Followers Military Security Company, which was originally stationed in the Ryukyus, also officially announced that they had joined the Alliance of Human Civilizations.

Also announced to join the Human Civilization Alliance, there are also the Fuso Hermit Society, which is also an island country and is most seriously harmed by the maritime civilization, as well as Lucia's "10003 Superhuman Force", America's "Jedi Legion" and other supernatural combat forces.

After all, for alien civilizations such as underground civilizations and maritime civilizations, ordinary armies can play a defensive role at most, and it is difficult to exert real strength on the frontal battlefield.
