In 2200 AD, the ocean was seriously polluted. Coastal cities in North America and Eurasian countries, including New York, Los Angeles, London, Marseille, Tokyo and Shanghai, were attacked by unknown creatures. Governments of various countries dispatched troops to fight back, although the unknown invaders were successfully attacked. Repulsed, but the city suffered heavy casualties, with as many as 10,000 dead, and nearly half of the construction roads were destroyed.
According to the reports of witnesses and journalists present, the invading creatures are similar in appearance to humans, but they seem to be marine creatures, and they are good at using sound waves as weapons, which can seriously damage the human auditory nervous system and cause brain damage. If several creatures made sounds at the same time, they could penetrate reinforced concrete, and the towering Empire State Building would collapse and disintegrate in an instant. When the two sides fought, the enemy often disrupted the radar communication with sound waves, and even the helicopter engine failed, and the soldiers were insane and killed each other. After that, a second raid occurred after a few months. The attack range extended to inland cities along the river, and the number of creatures was even more staggering. Many cities in the United States, Australia, and European countries were devastated, and Chinese cities such as Shanghai, Beijing, Dalian, and Xiamen were almost destroyed. Although the armies of various countries were dispatched in a timely manner, they still suffered heavy casualties. After the battle, San Francisco captured thirteen of these unidentified creatures and handed them over to a research team temporarily formed by the United Nations for observation and anatomical research.
This kind of creature has never been found before. They are very similar to humans. They have the same facial features, but have different hair colors, blue skin, ears like two fan-shaped fins, and are amphibious. If they are submerged in water, the two Leg cells quickly adhere and fuse to form fish tails. Only because of the fins on the arms, the webs between the fingers, the gills on the neck, and the scales on the legs, it resembles the siren, the sea monster with a deceiving voice in ancient Greek mythology, so scholars named it the sea monster.
The reason why the Kraken attacked humans is still unclear. Some environmental science experts believe that the ocean pollution is too serious, threatening the survival and reproduction of this creature, so they have to declare war on the original human beings. Humanists believe that these highly developed creatures have existed since ancient times. There are similar creatures in early myths around the world, such as the Greek sirens, the European mermen, and the Chinese mermen. These creatures live in the depths of the ocean all year round. After human civilization has developed too much and the land has become dangerous, they have hidden themselves to protect themselves. This time the attack was probably a last resort.
In 2201 AD, the request for human peace talks was not answered, the Kraken attack intensified, one-third of the coastal cities fell, and the number of human soldiers and civilians slaughtered could be counted in tens of millions. Humans have gradually developed helmets, armors and weapons that are resistant to sound waves.
In May 2203 AD, the United States, the European Union, Russia, China and Japan formed a naval battle coalition to attack the Kraken for the first time.
In January 2205 AD, the naval battle coalition successfully recaptured Los Angeles. In December of the same year, the Kraken entrenched in Dalian was annihilated by the Chinese army.
At the beginning of 2206 AD, the Kraken army besieged the headquarters of the naval battle coalition in Dubai. The siege lasted for 12 days. The famous American general, General Morris, died in battle. The potion escaped, and in June of the same year, the coalition forces were defeated across the board in the naval battle.
At the end of 2206, Noak perfected the Red Death Potion and poured it into the Kraken army. The Red Death spread rapidly among the Kraken army. The Kraken army then attempted to retreat to the sea, but was intercepted by the reorganized naval battle coalition forces, with more than half of the casualties. The remaining Kraken fled to the depths of the ocean. However, three Chinese submarines secretly tracked the Kraken unit and successfully detected five Kraken habitats.
In June 2207, five Russian submarines, four American submarines, and five German submarines dropped nuclear bombs on the Kraken habitat. The Kraken rout.
In 2212, all the Krakens were killed and injured, and dozens of young Krakens remained. They were sent to the Swedish Institute of Abnormal Biology for research by Professor Noak.
On April 13, 2219, Professor Noak published his world-shattering paper, proving that sirens can be domesticated. According to his research, the Kraken will have a similar but stronger emotion to a male or female Kraken/Human in a lifetime, which is similar to the combination of love and loyalty, and this emotion will last a lifetime without any regrets. betray. This kind of emotional bond is a biological feature, and is stimulated by a certain hormone different from human beings secreted by the pituitary gland to form a lifelong neurological change in the brain, so there is no possibility of empathy. A siren can only have one partner in his life, and if his partner dies, he will most likely commit suicide with his body.
In 2227, the United States used the emotional fetters of the Kraken to train the first Kraken team. The history of Krakens being used for military power begins here.
