1 1. Calamity

The world has been changed drastically since the calamity that happened 100 years ago. The calamity expanded the earth's size into 3 times bigger and mutated plants and animals into beasts. Humans have long-surviving this calamity.

Aside from the mutated beasts, many alien beasts come from a spatial rift that opens here and there. Humans have a tough time surviving that time until some people find out what power humans have since the calamity.

Humans can establish a blood contract with a beast. By contracting the beast is also resulting in a fascinating ability. All the first beast that is contracted will become a beast system that enables the user to check the data of the beasts around the world in a specific data format like a game format.

It also seems that in the system. The beast's name is not classified as a beast or a monster, but a cosmon shorten from Cosmic Monster. It is the first time humans can fight back the invading cosmon that have invading humans for years.

From there onwards, the humans that are capable of handling the cosmon are called Cosmon Tamer. Aside from Cosmon Tamer, another occupation is the most respected even more than cosmon tamer. They are called Evolution Master. Evolution Master's main job is to evolve a beast to the next level and sometimes enhance its grade.

The difficulty of the occupation is actually in the ways they use to evolve cosmon. Many people that have a system have seen some evolution ways for their cosmon, but the thing is that the evolution ways only listed the material, not the recipe. Hence, it is evolution master to make the recipe and test the recipe.

The latest discovery is that the better the first cosmon you contract, the better the system will be and the stronger evolution ways provided by the system. This discovery is based on the fact that most evolution masters contract their first cosmon in silver level, and at least their cosmon is epic grade.

This makes their system stronger and easier to identify stronger enemies and sometimes even provides materials and the recipe to evolve some low-level monster. The element and the type of the first cosmon are also essential.

The evolution ways depend heavily on the first cosmon. If the first cosmon contracted is fire element and canine type cosmon, the evolution ways available are usually are directed into fire element or canine type cosmon. Cosmon main Elements are divided into 2 elements: dark and light their secondary elements are usually basic elements.

"Quick take them out. They are a very important subject. We can't afford to let the enemies take them away. We need to let them get out from here." (The mysterious Doctor)

"Axel and Alexa, You're both are extremely important to me. You are my children but unfortunately, the enemies are too many and strong so I cannot protect you any longer. Please get out from here and escape as far as possible. You guys need to be stronger from now to be safe from them. I also have plant something that will help you guys grow stronger. Please forgive me for not giving you guys a happy life." (Mysterious Man)

That is the only memory that we have from our childhood. We only know that we are somewhat an extraordinary existence that even our father that we think is very strong, cannot defend us. We don't know anything aside from that; we have to be stronger, and we still don't know what our father mentions to us before sending us off.

We are now residing in a cave not far from the city. We choose here because we fear that the organization or people that target us will recognize us the moment we are outside, so we live in a cave and live by hunting some cosmon in the wild. We also sometimes search for some foods in the city and also hear some news about the world.

Even though we live far away from the town, we know some important things, thanks to people chatting here and there. We are 19 this year, and in a month, we will be officially 20 years old. Even though we have forgotten our childhood, we still remember our name and age and some stuff aside from childhood memories. That's why we can survive for so long in the forest.

"Axel. What is the thing that dad tells us about that will help us in the future? we have been living in this forest for the past ten years and there is nothing that happens to us. we also didn't awaken our body constitution that will make us a cosmon tamer. we will be 20 in 1 month. We have a very low chance to be awakened. I just think about what will happen to us in the future. we cannot possibly live like this hiding from them," Alexa said in a grumpy voice.

She knows that she is already helpless now, but she stills remember dad's word and wants to become stronger so she can avenge her dad. she still can endure this kind of lifestyle, but she doesn't care for how long she will be like this. she is afraid that she will die before avenging her father.

"I am also helpless at this point but what can we do aside from residing here and waiting for something that father says will help us. I know that you want to fight them as quickly as possible but we will only die in vain or will be taken to the experiment that they want. we will only make our father's sacrifice be in vain." Axel comforts his sister to calm her mind to make her not rush things.

"We have lived in this forest for many years and have hunted many cosmon and eat them. Our body is physically stronger than normal humans. We also have consumed many cosmon that even unawakened humans cannot eat because of the cosmic aura in the cosmon. but we can eat it normally now without any side effects. Even though our bodies are not awakened we have stronger bodies than normal. The times we awaken will come and we will be many times stronger than normal when we awaken. just endure it." Axel continues to comfort his sister, making his sister finally at ease.

They have lived together, and they live very dependently on each other. They cannot be separated by anything. They have lived so long together. They are now going back to the cave to rest.

In another continent very far from the location of the siblings. Inside one of a very dominant group in the continent. In the office, the group leader is very frustrated.

"Have you taken a lead to where the subject Gemini is? To think that he even uses his own life to let them get away. It is already 10 years and we haven't found them. Have you find any lead to them?" Asked the group leader to one of his men

"We haven't found any lead. I think they are already dead. It is almost impossible that they are alive in this world where Cosmon is now getting stronger and stronger." Said the big man in a suit

The leader glared back at the man before calming down and said something in a dispirited way, "Do you think why we need to attack their base when they still experimenting with it. It is because you don't know how terrifying they are. The thing is that they are not humans. They are monsters. You haven't seen them yourself how terrifying they are. That's why I cooperated with other groups to attack and now the most important subject has escaped."

The big man is confused before asking, "Boss, if you say they are terrifying, why are they never made any commotion until now. If it is like the thing you said that they are very scary, they will make commotion now."

The boss looked back to him and answered, "He probably seal the project Gemini memories so they can hide and hone their strength. The moment the memories are unsealed, it will be too late and we will be wiped out completely. Now get back to your searching. Search every corner of the world." said The boss ordering them to head out immediately.
