What's!! I'm Reincarnated!!?
Making Contracts With Monsters

The weakest Monster level was Common Monster, these Common Monsters were extremely weak monsters like poisonous plants and Monsters that could not attack others

The next level is Unique Monster, which is like Slime, Goblin, ogre and others, Monster of this level can already attack, but the potential of his attack is still a little.

The next level is Rare monster, a fairly strong monster, living in a deep forest, he is a monster feared by Hunter hunters in various kingdoms. Examples of these monsters are Minotaurs, Giant Spiders, and others.

The next level was the Mythical Monster, it was the most powerful monster in the forest forest, the unique and rare monsters were very afraid to meet this monster, for example King Kong, Holy Snake, and others, Garuda and others.

And the last level is the most powerful level, there are only 5 in the corner of the world, namely the Supreme Monster, monsters that have lived since before the primeval era, the first monster is the Dragon, Hydra, and others, Angel, Holy Spirit, Bloop.

And the powerful being that Zack encountered was Hydra, a 5-headed dragon that had every element power in its head. Hydra is attracted to Zack because Zack has pomegranate red eyes and is not affected by Hydra's deadly Aura.

But Zack here is still shocked and panicked because of the Hydra form is very dashing and creepy.

"Oh man why do you dare to set foot in this cave, how can you enter here?, when there are many powerful monsters here" Hydra said

"I-I don't know how I could have, when I woke up I was in here all of a sudden" Zack said

"(a unique child base) muttered Hydra"

Do you want to run a contract with me?(hhh, he should have died anyway because I am a supreme monster, it is impossible for ordinary humans to contract with Supreme monsters, his body will be destroyed to the fundamental stage) "Said Hydra while muttering

"E-em well, if it won't harm me, what was the contract before? is it mutually beneficial for each other? "

"The "contract was something that could be executed at any time, with Spirits and monsters. A contract will run smoothly if there is agreement from both parties, therefore the contract will immediately occur, for its benefits are very much, can help the work of the day, help increase strength and more" Hydra explained.

"Ehm, alright, but isn't that not beneficial to you? I'm just a weak human being and have very little power" Zack said

"You know, I agreed to this contract" Zack said

"(hihihihi whether it will be interesting this time)" Hydra said

Eventually they both run contracts, and strangely nothing happens to Zack's body, it should be if the human who was running a contract with a Supreme monster or a high-level monster his body would be destroyed and his existence lost until the fundamental stage.

But Zack is not affected by it, Hydra who is shocked to see it is immediately very interested by Zack and wants to follow Zack until the end of his life. After executing the contract Hydra evolved into a muscular and grumpy human.

Hydra has great respect for Zack, because nothing happened even though they have carried out the contract, Finally they both conquered Goa and went to the cave that had been the place of Hydra.

The aura of Hydra alone can even make a Monster instantly crumble into dust, exposed to a virus that can make the skin rot even to the severe effects of Radiation.

Hydra wants to test Zack's powers so that over time Zack will also grow stronger, The Hydra's aura and Hydra's power are suppressed and sealed by Zack within Zack's own soul in order for them to become normal Humans returning to the point where they are still stage 0.

"Oi Hydra, what good are you to call?, when Hydra is called, it's kind of weird" Zack said

"love me another name too, I'm tired of this one too" Hydra said

"Hmm you're called sebastian what won't you do? " said Zack

"what is sebastian, I think is good too, yaudah I will use the name sebastian" Hydra said

"By now you are Sebastian, I forgot to know my name, my name is Aizack Barbatov, I can be called Zack" Zack said

"Alright Mr Zack, let's conquer this world together!!! Hahahha" Sebastian said in a high tone.
