The so-called weapons of mass destruction literally mean weapons of mass destruction, that is, weapons with great power, weapons with very terrifying lethality and destructive power.

In ancient times, bows and arrows could be regarded as great killing weapons, with ultra-long attack distances and super lethality, which were enough to deter arrogance.

In the era of the earth, the nuclear weapons in the hands of the five hooligans can also be regarded as a weapon of mass destruction, and a nuclear bomb will disappear directly into a city, and it will be very easy to destroy the country and destroy the family if there are a few more. A country with a big killer weapon can really have the status of a real great power, and if the rabbit country at that time didn't have this town and country big killer, I don't know how many wars it would have to fight.

In the interstellar era, the empire's long-standing weapon of destruction is "space exile"! , especially the "Space Exile" released by the battle array combined by the Divine Dragon War can easily clean up a large area of the void.

The empire was able to destroy the Bona civilization, the Yanquan civilization, and the Chiyang civilization, the overlord of the extragalactic system under the foot of the river, basically it can be said that it relied on the empire's "space exile" weapon of mass destruction, and every time the empire was able to use inferior forces to confront the enemy's large-scale and powerful forces, and its own losses could be said to be minimal.

There are two things that cannot be relied on, one is the powerful defense built by space technology, which makes the empire's warships invincible, and the other is the powerful attack methods released by space technology, the most powerful of which can be called the "space banishment"!

The empire can smoothly occupy more than 50,000 river systems, and without the crushing strength led by space technology, it is simply impossible to accomplish it, unless every time it is like here in the Urfuus Galaxy, it uses biotechnology to release the terrifying "space biological virus".

Otherwise, it would be impossible to rely on a cannon or a gun to conquer such a vast territory, and it would be impossible for the empire to occupy such a vast territory in just over 1 million years, and spread the traces of the descendants of China all over the starry sky.

The importance of mass killing weapons is self-evident, this is enough to make a civilization deter the Quartet, and every civilization will try its best to study its own civilization of mass killing weapons, strengthen itself, and deter the enemy!

However, with the empire's breakthrough to reach level 6 cosmic civilization, the opponents it will face in the future will at least be level 6 cosmic civilizations that have also mastered some space technology, and these civilizations have also mastered space technology.

If the empire wants to have enough hole cards in the face of level 6 cosmic civilization, have the power to deter the Quartet, and have the strength to allow the empire to sweep a large number of star paths, the empire must research weapons that can be called a big killer weapon in the universe.

That's why Liu Qingquan is thinking about gathering these elders of the empire, and everyone will think of ways to find a way to find a direction together, and research a cosmic-level killing weapon for the empire, so that the empire will have a powerful force that is strong enough to sweep the level 6 cosmic civilization.

The cosmic-level mass killing weapon, in terms of power alone, is at least hundreds of millions of times more powerful than the "space exile" currently in the hands of the empire, which is enough to easily destroy a river system, and only such a powerful scientific and technological weapon can be qualified to be called a cosmic-level mass killing weapon.

How huge a river system is, just based on the Milky Way, the diameter of the Milky Way is more than 100,000 light years, and the thickness of the center is more than 30,000 light years.

Traditional nuclear weapons, antimatter weapons, powerful weapons, or energy weapons are simply not likely to affect such a large area.

The largest nuclear weapon is only a star, and the range that a star can affect by an explosion will not exceed 2 light-years at most, which is insignificant for a huge river system.

As for antimatter weapons, if there is enough antimatter, it can reflect all the matter in a river system, but it is impossible to have so much antimatter, and the refining of antimatter is very time-consuming and energy-intensive, and this is simply impossible.

As for energy weapons, it may be easy to destroy a river system by concentrating all the energy in the space-time power station of the abyss civilization, but the key is how to restrain and control such a huge amount of energy, and not every place can build such a huge space-time power station.

Therefore, if you want to research a terrorist weapon that can easily destroy a river system, among the scientific and technological means currently mastered by the empire, only space technology and biotechnology are the two scientific and technological means that can be realized.

Space technology is recognized in the universe as enough to make a civilization develop to the level of 7 cosmic civilization, many aspects of space technology have been studied, and there are too many means to destroy a river system, which is also the main direction of the future development of the empire, and it is also the most likely direction to achieve.

Only the means of biotechnology, if you just say that you destroy the creatures in a river system, in fact, the "space biological virus" researched by the Imperial Academy of Biological Sciences can almost be regarded as a cosmic-level killer, and the huge and prosperous Jadeite galaxy was wiped out by the empire's "space biological virus".

However, these "space biological viruses" are still somewhat useful for these low-level cosmic civilizations, and if they encounter civilizations with space technology, these civilizations can completely use space blockade, plus their own biotechnology means, etc., they should be able to deal with it relatively easily.

Moreover, there are still many conditions for the release of space biological viruses, the void can only quickly spread to the entire river system when it is released into the space-time ocean aorta in the river system, and if the cosmic enemy attacks their own river system on a large scale, the space biological virus is very useless.

The real big killer must be extremely powerful, the other party can't defend at all, and can attack freely, and the space biological virus is still quite far from the cosmic mass killer.

However, biotechnology is a very magical technology, and the civilization of biotechnology will not be inferior to the problems of space-time technology, and the advanced biotechnology civilization is also very terrifying, and it is recorded in the information of the alpha civilization, a biotechnology civilization that has developed to level 7.

Relying on a single seed can easily destroy a river system, and only the biotechnology civilization of the level 7 cosmic civilization can develop to the level of the 8th level cosmic civilization, which shows that biotechnology is also a broad road to the top cosmic civilization in the universe!

The empire has long ago researched the seeds of space creatures, which can take root in the void in a very short period of time, and then quickly grow and devour, and in many battles with the enemy, these biotechnological seeds have made countless cosmic civilizations think that they are devilish existences.

The empire's interstellar mining industry also uses a lot of biotechnology, and when it is often necessary to collect the resources on a planet, throw a few biotechnology seeds on the planet, and the resources on the entire planet will be swallowed up by these biological seeds, and then all of them will be purified into various raw materials.

It is very efficient, environmentally friendly, and very cost-saving in manpower, and it is also one of the most mainstream interstellar mining methods in the empire at present, and countless planets have been collected in this way.

In the past 1 million years, although the Imperial Academy of Biological Sciences has not been as popular as the Space Science Research Institute, it has always been able to maintain the top three positions among all the scientific research institutes in the Empire, and it has a fight with the Imperial Materials Science Research Institute led by Mo Qingming.

It can be seen that in the past 1 million years, the imperial biotechnology has also developed very rapidly, and countless achievements have emerged, especially the empire has occupied more and more river systems, and the genetic database that imperial biological scientists can collect is also getting bigger and bigger, and the foundation of biotechnology has been quite strong, with the possibility of developing cosmic-level mass killing weapons!

In Liu Qingquan's view, as long as proper guidance is carried out, coupled with hundreds of thousands of years of development, the empire can develop the corresponding cosmic-level weapons in both aspects.

Moreover, Liu Qingquan also knows from the seeds of the alpha civilization that there are those means that can be called cosmic-level mass killers in space technology and biotechnology, and he knows very well that although there is still a gap in the current scientific and technological level of the empire, in the next million years, since the empire intends to develop calmly, it is completely possible to study these big killing weapons.

Ever since he knew that the Abyss Civilization had built a space-time power station here in the Virgo galaxy cluster, and that Liu Wenjie's fleet had transmitted various materials about the Abyss Civilization from the front line, Liu Qingquan deeply felt that when the empire was competing with these cosmic civilizations, the empire's small arms and legs were still too thin and very weak.

This is also Liu Qingquan's position that has always been more irritable, the empire's strength is too weak, and many scientific and technological means in the past are too weak in the face of the cosmic civilization that has also mastered the corresponding scientific and technological means, and cannot achieve an overwhelming advantage, so the empire's side has to choose to calm down for a million years first.

If the empire has enough strength to crush the abyss civilization, the vast land and sparsely populated land are not exactly what the empire has always been pursuing, and in the final analysis, the strength is not good, so Liu Qingquan came up with the idea of researching a cosmic-level killing weapon!
