The Strongest Battle Pet Reincarnation of a Bard

Krilo's first transmigration happens in the land of Terra. A world of monsters, strange machines, and magic where everyone is bestowed with a system from nature itself to make them stronger. He leads a peaceful life in a village of the west. Until one day, strange machines arrive and destroy everything in its path. His village is turned into war headquarters by the coalition in an effort to stand a chance against the behemoth. Until suddenly one of the major kingdoms in the coalition massacres all of the inhabitants including poor Krilo all of the sudden. Krilo then undergoes a second reincarnation that takes place in the same world as his first reincarnation. But the difference is, he is now a battlepet for a boy with a class of bard. A fighting partner for his human in the form of an animal-like creature. However, his second reincarnation results in him and his human being jailed for life for a strange reason. Doomed to death and can't seem to level up, Krilo must find a way to seek out revenge against his adversaries in his previous life. But the idea of companionship does not fit his lifestyle. Should he stick to his human companion or take extreme measures to sever the ties? Soon after his escape, Krilo comes into contact with the power of The Void. [You are destined to be the strongest] [To gain level exponentially, the host must do 3 things: a. Strike your opponent b. Absorb the natural essence of another battlepet c. Absorb the natural essence of a human] Absorbing natural essence is the equivalent of absorbing someone's life. So, Have Krilo decided what to do with his bard? Is Terra will be the same as it used to be? Meanwhile, his human companion also has a mysterious power granted to him by The Nature Creator, the one that opposes The Void. Which one will bring grace and which one will bring calamity? ================== the above synopsis mostly applies to 30+ chapter of the book. So readers should be patient reading the beginning part first. What to expect: 1. adventure 2. intense worldbuilding (western fantasy) 3. somewhat a system novel (only the stat, skill, etc) 4. weak MC 1 (krilo) in the beginning, later may be classified as overpowered. Antihero 5. smart MC 2 (Niva) 6. No harem (for now) 7. excellent but rather serious story *The novel cover does not belong to me. All credits goes to the artist.
