"The battle of Pluto has allowed us to obtain more information." The headquarters of the Earth, China, and the Magic City Human Guardian Alliance is holding the highest military conference of the alliance.

Zhu Zhenxin, the captain of the Dragon Ball, said: "Based on the confession of the prisoners and our own reconnaissance results, the sea civilization currently has at least 700 space warships."

"We have already known the models of most battleships, including the Sailfish Cruiser, White Shark Battleship, etc. The enemy has a total of four star destroyers, the strongest of which is the giant whale mothership, followed by the whale shark sub-ship, which has been destroyed by us. In addition, there are two ships, Ichthy and Tortoise Shell, which we have not yet contacted."

"Seven hundred?" Wang Yu frowned slightly and said, "Now the total space warships of all human beings are only 350, and the enemies are twice as many as us! There are three star destroyers! One star destroyer is enough to dominate an area in the space battlefield!"

"Before the decisive battle, we must increase the number of warships as much as possible." Du Xingyu said, "In two months, we will have a second Star Destroyer, Nirvana."

Nirvana is an inverted pyramid-type star destroyer built completely imitating the Dragon Ball. Humans do not have so much time to develop a new generation of star destroyers, so they use the fastest time to replicate the Dragon Ball.

"Other warships will be built quickly, and strive to make the total number of warships reach 400 before the final battle."

"There are still too much difference in number. Now the sea tribes gather their troops together. The blitzkrieg like the Battle of Pluto before would not happen again." Francis said, "The next battle will inevitably be a head-on decisive battle!"

"Commander Du." Wan Yan asked the general fleet commander of Kunpeng Fleet: "We are not afraid to fight against the conventional warships of the sea civilization. But how should we deal with their giant whale mothership?"

This is also a problem that everyone is worried about. In the description of the sea captives, the combat power and super weapons of the giant whale mothership can sweep across an entire fleet!

Du Xingyu was also a little in trouble. He said: "The giant whale mothership is comparable to an asteroid in its mass and volume alone! It has the same glial laser and electromagnetic protective film as the Whale Shark, so our lasers and electromagnetic weapons are useless to it."

"Only kinetic weapons and proton bombs can cause damage to it."

"Analysis of the size and defense capabilities of the Giant Whale, our existing kinetic energy weapons should not cause any damage to it," military expert Anushka analyzed, "and there are proton torpedoes."

"The enemy must have learned about the proton torpedo information, so they will definitely defend against the proton torpedo in the next battle. I'm afraid that our proton torpedo will not be able to break through the Giant Whale's space missile interception system at all."

"Anushka is right. The enemy's giant whale mothership is a super war machine! If we don't have the weapon to destroy this super war machine, we have almost no chance of winning!" Du Xingyu said, "At present, my team and I are studying the wreckage of the Whale Shark, hoping to find some ways to destroy the giant whale mothership."

"Commander Du, everything depends on you!" Wang Yu said solemnly, "We can study tactics. But in the competition of scientific and technological weapons, only you can lead us!"

"Mr. Du, I wish you a smooth research!" Garcia said.

...

Du Xingyu and the top human space weapons experts are urgently studying the wreckage of the Whale Shark, trying to find a way to conquer the giant whale mothership.

"Analysis of the glycoefficient protective film of Whale Shark shows that this is a special high-temperature resistant, high reflectivity material with fluidity," said materials expert Milton. "We have reversely analyzed its composition in the laboratory, which is how to make it still has difficulties."

"Well, I will take time to take a look." Du Xingyu also attaches great importance to this kind of gelatinous protective film. Without the warship shield technology, this protective film can minimize the damage suffered by warships.

But it seems to be very difficult to manufacture, otherwise the fleet of the sea civilization would not be owned by Star Destroyers, and conventional warships did not.

"Command, we also analyzed the hull material of the Whale Shark." Milton continued to report, "This is a high-intensity space metal with memory functions. The entire piece of warship armor can withstand the power of missiles at the explosion level of hydrogen bombs."

"If the warship armor of the giant whale mothership is two meters thicker than the Whale Shark, or if the giant whale mothership has double-layer warship armor, any space missiles and kinetic energy weapons we have in existence will not be able to penetrate its warship armor at all!"

"Even if their warship armor is damaged, it will not cause great damage to the hull! If the enemy arranges protective layers of electric field weapons on the warship armor, our proton torpedo effect will be greatly reduced!"

"Absolute defense plus absolute attack, how can you fight?" These experts were unsure. The more they studied them, the more guilty they felt. The giant whale mothership of the sea civilization was really a battleship that crushed them in all aspects.

"There must be new weapons that can destroy the defense of the giant whale mothership." Du Xingyu had already started to think about it, and he asked, "What do you think?"

"Destroy the giant whale mothership? If it is a laser weapon, it must have at least 100 times the energy of the current Dragon Ball laser cannon to destroy the enemy's gel protective film and warship armor!" said the laser weapon expert.

"The same applies to electromagnetic weapons, but it may be much better if they are combined with kinetic energy weapons or missile weapons to make a combined weapon, first destroying the hull and then using electromagnetic bombs." Another spoke.

"Crash with an asteroid? Just like the God of Death, mobilize all our asteroid strikers and hit the giant whale!" someone suggested.

"This plan doesn't work. The giant whale mothership is not a target. It can move at high speed. And don't forget that the giant whale itself is also a powerful war machine! It can smash asteroids!"

"It is not feasible to improve power and energy output for the time being." Du Xingyu said directly, "We don't have much time, and it is impossible to break through energy technology in a short time."

The most advanced energy they can use now is nuclear fusion energy. The fusion reactor on the Star Destroyer is now at the peak.

"We need to change our thinking. Put the above weapons aside for the time being. Think about new weapons!" Du Xingyu said.

After some discussion and thinking, an expert suddenly said: "I have an idea. Commander Du, the robot spy of the sea civilization, Motley, once wanted to use meteorological weapons to attack the Earth's atmosphere and create hurricanes and lightning, but it was intercepted by our space defense system."

"Now the enemy is gathering on Neptune, which is a gas giant planet with a rich atmospheric environment. We use meteorological weapons to create super thunderstorms, which may have unexpected effects!"

Du Xingyu's eyes lit up and he said, "Good idea, the number of enemy warships is far better than that of us. Deploying meteorological weapons on Neptune and creating thunderstorms is indeed a large-scale attack method."

"This should have a certain effect on conventional warships. I'm afraid it's a little bit short of it when dealing with giant whale motherships."

Du Xingyu still does not believe that meteorological weapons can destroy the giant whale mothership, and thunderstorms are nothing more than large-scale and ultra-high-energy electric field weapons. They are similar to the function of proton torpedoes, and the giant whale mothership can also avoid or defend.

He followed this idea and a flash of inspiration in his mind, saying, "You reminded me that the enemy is not in the vacuum now, but in the atmosphere of Neptune!"

"They are extracting hydrogen and helium from Neptune's atmosphere as nuclear fusion energy. The enemy is in the atmospheric environment... we can use resonance weapons!"

"Resonance Weapon?" When the experts heard Du Xingyu's words, they were stunned at first, and then reacted.

Resonance refers to the situation where a physical system vibrates at a larger amplitude than other frequencies at a specific frequency; these specific frequencies are called resonance frequencies.

This physical phenomenon sometimes causes great damage. For example, in the early 19th century, a group of Napoleon soldiers walked across the bridge in a row, because the frequency of walking in a row was consistent with the natural frequency of the bridge, the vibration of the bridge was strengthened. When the amplitude exceeded the maximum, the bridge broke.

Resonance weapons use this principle to destroy strong enemy targets in a very inconspicuous way!

"Yes, the enemy is in Neptune's atmosphere. We can emit ultrasound waves of specific frequencies, use the Neptune atmosphere as a propagation medium to resonate the hull armor of the giant whale mothership until it breaks!"

"The idea of ​​Commander Du is so feasible! It is more reliable than other weapons!" They sincerely praised.

Du Xingyu continued to analyze and said: "The two biggest problems of resonance weapons are: one is the propagation medium. As long as the enemy is in the atmosphere of Neptune, there is no problem."

"In addition, we need to know the natural frequency of enemy warship materials, and we must know the precise frequency to ensure that the warship armor resonates!"

"Now we have the hull material of the Whale Shark, which is the same as the hull of the giant whale mothership. We can use it to measure the natural frequency of this material. Both problems have been solved."

"Now, we only need to find a way to create a large ultrasonic device that creates atmospheric resonance to ensure that its propagation distance is far enough to cover the entire giant whale mothership!"

...

The weapon research and development team immediately started, and two new weapon projects were built on Du Xingyu's technology simulator.

"Thunderstorm Generator" of meteorological weapons.

and the resonant weapon's "Planetary Impact Drum".

Humans have long studied the meteorological weapon of "Thunderstorm Generator" and also analyzed the meteorological weapons of the Marine civilization, so the research completion rate was more than 70% at the beginning. There is also an expert meteorological weapon research and development team responsible, so Du Xingyu does not need to worry too much.

He devoted all his energy to "Planetary Impact Drum". The more he studied it, the more Du Xingyu discovered the terrifyingness of this weapon.

It is like the butterfly effect, causing huge destructive power with subtle changes.

Suppose there is a planetary impact drum with sufficient power that continuously releases ultrasound waves, causing resonance in the planet's atmosphere, and conducts this resonance to the planet's surface, or even slowly conducts it to the planet's core.

After thousands or even tens of thousands of years, the amplitude continues to expand, and the core of the planet may be shattered due to resonance, and the entire planet will be broken!

This is a super weapon that can destroy a planet, in theory!
