Start sweeping the universe by rubbing the CPU with your hands.

During subsequent analysis, a large amount of data about pterosaurs was transmitted back to the solar system. After analysis by Han Yang and the scientific advisory team, more information was presented to people.

“The short-term burst maneuverability exceeds that of a Stardust-class battleship, but it is not long-lasting and the overall acceleration capability is not strong. It is suspected to be related to its energy reserve.

It has nuclear fusion or nuclear fission capabilities and electric propulsion capabilities, but its unit efficiency lags far behind our warships.

The pterosaur does not have the ability to attack with electromagnetic guns. Its main attack methods are impact and bite, which is consistent with the data of the Silver Alliance. At present, the defensive capabilities of the Stardust-class battleship are sufficient to withstand a single pterosaur attack. However, if multiple pterosaurs attack and collide together, there is a high possibility of destroying the Stardust-class battleship.

They are highly concealed, and the distance between pterosaurs is relatively far, making it difficult to detect them on a large scale.

By specially designing targeted weapons and targeted tactics, we will have a great advantage in facing the pterosaur swarm. On the frontal battlefield, we are not afraid of the pterosaur swarm at all.

But that's not really the point. The point is... combined with the characteristics of the pterosaurs, we believe that the pterosaur clusters are likely to actively avoid fighting with us on the frontal battlefield.

We believe that the more likely combat method of the pterosaur cluster is to rely on concealment and numbers to avoid our battleship cluster, and then penetrate into the planet to face our rear.

Once a pterosaur breaks through the planet's defenses and lands on the planet's surface, then... it is not impossible for a pterosaur to destroy a city and kill tens of millions of people. "

Reminiscent of the image of pterosaurs descending into the city, everyone in the high-level military meeting, including the scientific advisers, fell silent.

With the pterosaur's physical capabilities, even the thick armor of the Stardust-class battleship can be dented by a violent impact, and it can easily destroy a building.

Judging from the current data, it is easy for a pterosaur to fly at supersonic speeds in the atmosphere, and just the wind caused by supersonic flight near the earth can destroy countless urban buildings.

The most important thing is that pterosaurs have no scruples in human cities. But human warships have many restrictions.

Only in interstellar space can various weapons be used without restrictions. On the surface of the planet, a single electromagnetic gun salvo can launch tens of thousands of electromagnetic gun projectiles, releasing an energy equivalent to the explosion of tens of thousands of tons of TNT explosives.

Using battleship-grade weapons to fight pterosaurs in a human urban environment? By the time the pterodactyl is not killed, the city will be destroyed by itself.

"So... in the face of this pterosaur swarm attack, the focus of the operation is not the battle on the frontal battlefield, but to prevent the pterosaurs from breaking through the defense line and entering the planet's surface?"

"Yes. In addition, there is another possibility that needs to be prepared for.

We believe that it is very likely that the pterosaur swarm will not focus on attacking the planet's defense line. The more likely tactical option is to rely on one's own concealment to lurk in the star system and continue to harass planets and interstellar space. "

Han Yang also began to feel troubled.

Yes, on the frontal battlefield, we pterosaurs, who rely on our bodies, cannot beat you who rely on your wisdom. But we will not fight you on a frontal battlefield.

We will lurk, conduct sneak attacks on merchant ships and civilian ships, attack bases on small planets with weak defenses, and occasionally send out dozens or hundreds of pterosaurs to try to penetrate the defense lines of large planets. You will never have peace.

Every major planet must be defended to the highest standards, because as long as one pterosaur is infiltrated, it may cause millions of casualties.

Every merchant ship and civilian ship must be escorted, otherwise it may be eaten by pterosaurs.

Every alien base must be heavily defended. Once the defense is low, it may be swallowed whole by the pterosaurs.

The focus of civilization will have to shift from development to defense against pterosaurs. Industrial and commercial activities will be severely stagnant because space is no longer safe.

If this continues, the entire civilization may be brought down. Once the defense holes are exposed, it will be a carnival for the pterosaurs.

Tens of thousands, hundreds of thousands, or even more pterosaurs will break into the planet and devour all life on the planet, including humans.

Han Yang recalled some of the hunting techniques of the wolves.

Faced with heavily guarded humans, wolves will not attack hard, but will constantly harass them, making humans tired. After the loopholes are exposed, he will deliver a fatal blow and turn humans into his own food to eat.

These pterosaurs...are really in the same line as those beasts. But in the face of this kind of fighting style that is full of beasts, intelligent humans have no good solution.

Facing the solemn-looking civilization leaders, Han Liang looked calm and said slowly: "We humans... are invincible. As long as we are united, no enemy can defeat us."

Time passed by in a hurry, and more than a hundred years passed in the blink of an eye.

Motan Galaxy. A large number of urban populations on dwarf planets and asteroids were evacuated, the cities were abandoned, and all were resettled on large planets.

Tens of thousands of warships tightly guard every major planet, while tens of thousands of other warships are roaming in space.

The entire galaxy is on full alert, not daring to relax at all.

Under this situation, a large-scale pterosaur swarm came.

Just as Han Yang had expected, after the initial head-on collision, the pterosaur group found that it was unable to confront them head-on, and immediately turned to a stealth and harassment battle. There are more than a billion pterosaurs in total, hidden in the vast space, hidden in planetary rings, hidden in asteroid belts, and even in the gas of gaseous planets.

The Motan civilization subsequently changed its style of play and began to split the fleet into small teams. With the cooperation of a large number of detection satellites and automated combat devices, it gradually searched and eliminated.

The flames of war began to burn throughout the star system.

A large number of pterosaurs were killed under the siege of the battleships, and a large number of Motan battleships were besieged by the pterosaurs. Their armor was eventually broken, and the soldiers were eaten by the pterosaurs.

Due to a certain defensive error, dozens of pterosaurs even rushed into the surface of the planet.

Looking at the battle scenes shared by Motan Civilization, watching a pterosaur with a length of dozens of meters flying over the city, the wind blowing down high-rise buildings, seeing the city in chaos, and hundreds of thousands of people dying tragically In the end, the fleet was mobilized and the city was almost destroyed before these dozens of pterosaurs were eliminated. The top leaders of various civilizations who participated in the Yuanshan Alliance meeting felt heavy in their hearts.

This is the Motan civilization after being "encouraged" by human civilization and the comprehensive strength of the civilization has been greatly improved. If it were in the past, the Motan civilization might have been completely destroyed.

In space routes, small fleets were frequently attacked and completely destroyed by pterosaurs. Commercial transportation has almost come to a standstill, because under such circumstances, commercial and civilian ships are almost seeking death if they dare to go into space.

The entire civilization suffered heavy losses.

"This is the most powerful enemy our civilization has ever encountered since its emergence. On behalf of our Motan civilization, I request assistance from the Alliance."

Faced with requests for help, the top leaders of the three major civilizations remained silent.

The representative of Motan Civilization smiled sadly, shook his head, and no longer insisted on this topic.

Several decades later, while the Motan civilization was still struggling to persist, the pterosaurs flying towards the Yuanshan galaxy finally arrived.

At this time, Yuanshan Civilization finally showed the foundation of its old top second-level civilization.

After hundreds of years of full preparation for war, countless detection satellites, forts, interstellar mine clusters, etc. were released into space. The Yuanshan fleet launched an all-out attack, struggling to clear out the pterosaurs in space.

Although the pterosaurs did not rush to the surface of the planet, the traffic between the planets in the Yuanshan Galaxy was almost at a standstill. At the same time, under the siege of the pterosaurs, it often happened that lone battleships and even small fleets were eaten.

Technological and economic development has almost come to a standstill. A large amount of social wealth had to be funneled into the war, social welfare plummeted, and the entire civilization suffered heavy losses.

It seems that Yuanshan Civilization is also unlikely to solve the pterosaurs in a short time.

After that comes the Fix civilization.

Although there are samples provided by the two civilizations of Motan and Yuanshan, the Fick civilization can be more targeted and fight against the pterosaurs with higher efficiency. However, due to the comprehensive strength of the civilization, at the beginning of the war, the Fick civilization The Si civilization still fell into the same disadvantages as the Motan civilization.

Although the pterosaurs have not yet broken through the defense line, according to the judgment of the human military observation team, such a thing will happen sooner or later, and it should not be too far away.

For a time, three of the four civilizations in the entire Yuanshan Star Territory were struggling, and only the solar system maintained peace and stability.

But even so, the entire solar system has entered the martial law stage ahead of schedule. Non-essential space navigation has been banned, and warships will also be dispatched to escort key space navigation, such as material transportation and industrial production.

A large number of fleets were mobilized around, and there was a killing spree.

Under the call of the human government, human civilization has also entered a stage of full preparation for war.

Countless factories are roaring day and night, and tens of billions of human workers are doing their best.

The tragic scenes from the remaining three civilizations have been revealed to human society. For a time, "pterosaur" became the most frequently mentioned word.

Countless people are worried. When it comes to the most vital interests, everyone feels the huge pressure.

Han Yang also temporarily diverted his computing power from scientific research and invested it in industrial production.

In places where people can't see, up to a million unmanned factories are roaring day and night, day and night.

Countless interstellar mines, turrets, missiles, satellites, and even small unmanned warships have been produced and continuously added to space.

Under such circumstances, the battle report finally came from the front line.

"Traces of pterosaurs observed..."

A huge group of pterosaurs has now emerged from the vast and deep universe and is heading towards the small solar system. (End of chapter)
