"Pluto World War I, let''s get more intelligence." earth, China, Mordor, human Guardian alliance headquarters, at this time, the alliance''s highest military conference is being held.


    Zhu Zhenxin, captain of Longzhu, said: "according to the prisoner''s confession and our own investigation results, the marine civilization still has at least 700 space warships."


    "We already know the models of most warships. They are sailfish cruisers and white shark battleships that have already appeared. The enemy has four star destroyers, the strongest of which is the giant whale mother ship, followed by the whale shark sub ship, which has been destroyed by us. In addition, there are the ichthyosaur and the tortoise shell, which we haven''t contacted."


    "700?" Wang Yu frowned slightly and said, "now there are only 350 space warships for all mankind, and the enemy is twice as many as us! There are also three Star Destroyers! One Star Destroyer is enough to dominate an area in the space battlefield!"


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


    Nirvana is an inverted pyramid Star Destroyer built entirely after the dragon ball. Humans don''t have so much time to develop a new generation of Star Destroyers, so they engrave the dragon ball in the fastest time.


    "Other warships will also pay close attention to manufacturing and strive to make the total number of warships reach 400 before the decisive battle."


    "The number is still too poor. Now the sea people have gathered their forces together, and the Blitz like the battle of Pluto can''t happen again," Francis said. "The next battle must be a tough showdown!"


    "Commander Du." Wan Yan, commander of the general fleet of Kunpeng fleet, asked, "we are not afraid to confront the conventional warships of the sea civilization. But how should we deal with their giant whale mother ship?"


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


    Du Xingyu was also a little difficult. He said: "the mass and volume of the giant whale Mothership are just like an asteroid! It has the same colloidal anti laser and electromagnetic protective film as the whale shark, so our laser and electromagnetic weapons are useless to it."


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


    "Based on the analysis of the size and defense capability of the giant whale, our existing kinetic energy weapons should not damage it," military expert anushka said. "There are proton torpedoes."


    "The enemy must have known the information of proton torpedoes, so they will defend proton torpedoes in the next battle. I''m afraid our proton torpedoes can''t break through the space missile interception system of the giant whale."


    "Anushka is right. The enemy''s whale Mothership is a super war machine! If we don''t have weapons that can destroy this super war machine, we have little chance of winning!" Du Xingyu said. "At present, my team and I are studying the wreckage of whale shark, hoping to find some ways to destroy the whale mothership."


    "Commander Du, it''s up to you!" Wang Yu said solemnly, "we can study tactics. But in the competition of scientific and technological weapons, only you can lead us!"


    "Good luck with your research, Mr. Du!" Garcia said.


    ……


    Du Xingyu and mankind''s top space weapons experts are urgently studying the wreckage of the whale shark, trying to find a way to conquer the giant whale mothership.


    "The analysis of the colloidal protective film of whale shark shows that it is a special high temperature resistant and high reflectivity material with fluidity," said Milton, a material expert. "We have reverse analyzed its composition in the laboratory, that is, how to manufacture it is still difficult."


    "Well, I''ll take time to have a look." Du Xingyu also attaches great importance to this colloidal protective film. Without warship shield technology, this protective film can minimize the damage suffered by warships.


    But its manufacture seems very difficult, otherwise the fleet of sea civilization will not be owned only by Star Destroyers, but not by conventional warships.


    "Commander, we also analyzed the materials of the whale shark." Milton continued to report, "this is a space metal with high strength and memory function. The whole warship armor can resist the missile power of hydrogen bomb explosion."


    "If the battleship armor of the whale Mothership is two meters thicker than the whale shark, or if the whale Mothership has double-layer battleship armor, any of our existing space missiles and kinetic energy weapons can not penetrate its battleship armor!"


    "Even if their warship armor is damaged, it can''t cause great damage to the ship! If the enemy arranges the protective layer of anti electric field weapons in the warship armor, our proton torpedo effect will be greatly reduced!"


    "Absolute defense plus absolute attack, how to fight?" these experts have no bottom in their hearts. The more they study them, the more guilty they are. The giant whale Mothership of the sea civilization is really a warship that crushes them in all aspects.


    "We must have new weapons that can destroy the defense of the giant whale mothership." Du Xingyu began to think about it. He asked, "what do you think?"


    "Destroy the whale Mothership? If you rely on laser weapons, you must have at least 100 times the energy of the current Longzhu laser gun to destroy the enemy''s colloidal protective film and warship armor!" said the laser weapons expert.


    "The same is true for electromagnetic weapons, but it may be much better to make a combined weapon with kinetic energy weapons or missile weapons, destroy the ship body first, and then use electromagnetic bombs." another person spoke.


    "Strike with an asteroid? Like the death star, gather all our asteroid impactors and hit the giant whale!" someone suggested.


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


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


    Now the most advanced energy they can use is nuclear fusion energy. The fusion reactor on the Star Destroyer is the peak that can be reached now.


    "We need to change our thinking, put the above weapons aside for the time being and think about new weapons!" Du Xingyu said.


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


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


    Du Xingyu brightened his eyes and said, "good idea. The number of enemy warships is far greater than ours. Putting weather weapons on Neptune and making thunderstorms is really a way of large-area attack."


    "This should play a certain role against conventional warships. I''m afraid it''s a little bad against giant whale motherships."


    Du Xingyu still doesn''t think that meteorological weapons can destroy the whale mothership. Thunderstorms are nothing more than large-scale and ultra-high-energy electric field weapons. Similar to the role of proton torpedoes, the whale Mothership can also avoid or defend.


    He thought along this line, his mind flashed and said, "you remind me that the enemy is not in a vacuum, but in Neptune''s atmosphere!"


    "They are pumping 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?" hearing Du Xingyu''s words, the experts were stunned first and then reacted.


    Resonance refers to the situation that a physical system must vibrate at a specific frequency with a greater amplitude than other frequencies; These specific frequencies are called resonant frequencies.


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


    Resonance weapons use this principle to destroy solid enemy targets in a very humble way!


    "Yes, the enemy is in Neptune''s atmosphere. We can launch ultrasound with a specific frequency and use Neptune''s atmosphere as the transmission medium to resonate the armor of the whale Mothership until it breaks!"


    "Commander Du''s idea is too feasible! It is more reliable than other weapons!" they sincerely praised.


    Du Xingyu continued his analysis and said: "the two biggest problems of resonance weapons are the propagation medium. As long as the enemy is in Neptune''s atmosphere, there will be no problem."


    "In addition, we need to know the natural frequency of enemy warship materials. We must know the accurate frequency to ensure the resonance of warship armor!"


    "Now we have the hull material of whale shark, which is the same as that of the giant whale mother ship. We can use it to measure the natural frequency of this material. These two problems have been solved."


    "Now, we just need to find a way to create a large ultrasonic device for atmospheric resonance to ensure that its propagation distance is far enough to cover the whole whale Mothership!"


    ……


    The weapon R & D team immediately started, and two new weapon projects were built on Du Xingyu''s science and technology simulator.


    Thunderstorm generator for meteorological weapons.


    And the planetary impact drum of resonance weapons.


    Thunderstorm generator, a meteorological weapon, has long been studied by humans, and it has also analyzed the meteorological weapons of the sea civilization. Therefore, at the beginning, the completion rate of the research exceeded 70%. An expert''s Meteorological weapon R & D team is responsible, so Du Xingyu doesn''t need to worry too much.


    He devoted all his energy to the planetary impact drum. The more he studied, the more terrible Du Xingyu found this weapon.


    Like the butterfly effect, it causes great destructive power with subtle changes.


    Suppose there is a planetary impact drum with sufficient power that continuously releases ultrasonic waves, causes the resonance of the planetary atmosphere, and transmits this resonance to the planetary surface, or even slowly to the planetary core.


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


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


    Its biggest problem is that the preparation time is too long. The natural frequency of the destruction target must be known when it is launched, and the medium is needed to conduct resonance. If the enemy is on guard, this weapon will be of little use.
