The so-called killing weapon literally means a weapon of mass destruction, which is a weapon with great power, a weapon with very terrifying lethality and destructive power.

In ancient times, bows and arrows could be regarded as large killing weapons, with extremely long attack distances and super lethality, which were enough to shock the arrogant.

In the Earth era, the nuclear weapons in the hands of the five major gangsters can also be regarded as large killing weapons. If a nuclear bomb goes down, a city will disappear directly. If a few more, it will be easy to destroy the country and the family. Only countries with large killing weapons can truly be said to have a real status as a big power. If the Rabbit Kingdom did not have this large killing weapon at that time, I don’t know how many wars it would have to fight.

In the interstellar era, the empire's weapon has always been "space exile"! Especially the "space exile" released by the battle formation combined by the Dragon War can easily clean up a large area of ​​voids.

The empire was able to destroy the Bona civilization, defeat the Yanquan civilization, and step on the hegemony of the extra-river galaxy system, Chiyang civilization, which can basically be said to rely on the empire's "space exile" killing weapon. Every time the empire can use its inferior forces to fight against the enemy's large-scale powerful forces, and its own losses can be said to be minimal.

The things that cannot be relied on are two things, both of which are powerful defense power built with space technology, which makes the imperial warships invincible. The other is the powerful attack method released by space technology. The most powerful one among them, the one that can be called "space exile"!

The empire was able to successfully occupy more than 50,000 river galaxies, and it was impossible to complete without the crushing strength led by space technology, unless every time it was like the Jade Mahara galaxy, using biotechnology means to release the terrifying "space biological viruses".

Otherwise, it would be impossible to capture such a vast territory with one shot and one shot, and the empire would not have occupied such a vast territory in just over 1 million years, scattering the descendants of China all over the starry sky.

The importance of a big killer is self-evident. This is something that is enough to shock a civilization. Every civilization will try its best to study the big killer of its own civilization, strengthen itself and shock the enemy!

However, as the empire breaks through to level 6 cosmic civilization, the opponents they will face in the future will at least master some of the 6 cosmic civilizations of space technology. These civilizations also master space technology, space blockade and space folding advantages are gone, and the "space exile" killer weapon researched with space technology can no longer match its own identity as the killer weapon.

If the Empire wants to have enough trump cards when facing a level 6 universe civilization like before, it has the power to shock all directions, and has the strength to allow the Empire to sweep a large number of star paths, the Empire must develop weapons that can be called a weapon in the universe.

That's why Liu Qingquan thought of summoning the elders of these empires. Everyone thought of ways to find a direction together, and developed a cosmic killer weapon for the empire, so that the empire could have powerful power that could sweep the level 6 cosmic civilization.

In terms of power alone, the cosmic-level killer weapon is at least hundreds of millions of times stronger than the "space exile" currently mastered by the empire, and is enough to easily destroy a river galaxy. Only such powerful technological weapons can be qualified to be called the cosmic-level killer weapon.

How huge a river is? Just calculated by the Milky Way, the diameter of the Milky Way is more than 100,000 light-years and the center thickness is more than 30,000 light-years. With such a huge spatial range, the general technological range has no impact on it at all.

Whether it is traditional nuclear weapons, antimatter weapons, powerful weapons, or energy weapons, it is simply impossible to have an impact on such a huge range.

The biggest increase in nuclear weapons is just a star. The range of impact of a star's explosion will not exceed 2 light years at most, which is insignificant for a huge river galaxy.

As for antimatter weapons, if there is enough antimatter, it can react to all matter in a river sphere, but there is no way there will be so much antimatter. The refining of antimatter can consume a lot of time and energy, and this is simply impossible.

As for energy weapons, it may be possible to concentrate all the energy in the Abyss Civilized Space-Time Power Station to easily destroy a river galaxy, but the key is how to constrain 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 develop a terrifying killer that can easily destroy a river galaxy, the only ones that can be realized among the current scientific and technological means that the empire currently masters are space technology and biotechnology.

Space technology is a technology recognized in the universe that is sufficient to develop a civilization to the level of level 7 in the universe. After many aspects of space technology have been studied, there are too many means to destroy a river galaxy. This is also the main direction of the empire's future development and the most likely direction to achieve.

Only biotechnology means. If you just want to destroy a creature in a river galaxy, the "space biological virus" studied by the Imperial Institute of Biological Sciences can be regarded as a cosmic killer. At that time, the extremely huge and prosperous Jade Mahara galaxy was completely wiped out by the empire's "space biological virus".

However, these "space biological viruses" are somewhat useful to these medium and low-level cosmic civilizations. If you encounter a civilization with space technology, these civilizations can completely use space blockade, and their own biotechnology methods, etc., it should be able to cope with it more easily.

Moreover, there are many conditions for the release of space biological viruses. Only when the void is released into the space-time aorta in the river galaxy can it spread rapidly to the entire river galaxy. If the enemy of the universe attacks its own river galaxy on a large scale, space biological viruses will appear to be very useless.

A real killer must have extremely powerful power, and the opponent cannot defend at all, and can also use attacks freely. Space biological viruses are still quite far from the cosmic killer.

However, biotechnology is a very magical technology. The civilization of biotechnology will not be inferior to the problem of time and space technology. Advanced biotechnology civilization is also very terrifying at the same time. The data of the Alpha civilization records that a biotechnology civilization has developed to level 7.

Relying on a seed, a river can be easily destroyed. Biotechnology civilizations with only level 7 cosmic civilization can develop to level 8 cosmic civilization. It can be seen that biotechnology is also a smooth road to the top cosmic civilization in the universe!

The empire had already studied space biological seeds a long time ago, which could take root in the void in a very short time, and then grow and swallow quickly. During the battle with the enemy many times, these biotech seeds made countless cosmic civilizations think that they exist like devils.

The interstellar mining industry of the empire also uses a large amount of biotechnology. When it is often necessary to collect resources from a planet, a few biotechnology seeds will be left on this planet. The resources on the entire planet will be swallowed 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-effective. It is also one of the most mainstream interstellar mining methods in the empire. Countless planets are collected in this way.

For more than 1 million years, although the Imperial Institute of Biological Sciences has not had the popularity and leading position as the Academy of Space Sciences, it has always maintained its top three among all the scientific institutes of the Empire, and is comparable to the Imperial Materials Institute led by Mo Qingming.

It can be seen that over the past 1 million years, Empire Biotechnology has also developed very rapidly in this regard, and countless achievements have emerged, especially the more and more rivers occupied by the Empire, and the gene databases that Empire biological scientists can collect are becoming larger and larger. The foundation of biotechnology has become quite strong and has the possibility of developing cosmic-level killing weapons!

The Empire has developed very fast in both space technology and biotechnology, and has achieved a lot of achievements, and its foundation is already strong enough. In Liu Qingquan's view, as long as appropriate guidance is carried out and hundreds of thousands of years of development, the Empire can study corresponding cosmic-level killers in both aspects.

Moreover, Liu Qingquan also knows about space technology and what are the methods in biotechnology that can be called cosmic killers? It is clear that although the empire still has some gaps in its current technological level, in the next million years, since the empire intends to develop peacefully, it is entirely possible to research these killers.

Since knowing that the Abyss civilization has built a space-time power station in the Virgo galaxy cluster and the various information about the Abyss civilization transmitted back from the front line by Liu Wenjie's fleet, Liu Qingquan deeply felt that when the empire was comparing with these cosmic civilizations, the empire's little arms and calves were still too thin and seemed very weak.

This is also Liu Qingquan's position that has always been relatively irritable. The empire is too weak. In the past, many technological means seemed too powerless when facing the cosmic civilization that also mastered the corresponding technological means, and could not gain an overwhelming advantage. Therefore, the empire had to choose to calm down for a million years first.

If the empire had enough strength to crush the abyss civilization, the vast land and sparse population were what the empire had always pursued. In the end, it was still not strong enough, so Liu Qingquan had the idea of ​​developing a cosmic-level killing weapon!
