Kevin: "Why do you Choose Poison"
Adam: Apart from the Women, the most dangerous thing that would kill even the God Slayer Stage, And is perfect for assassinations and the most important thing is that I could take revenge on those bitches exactly how she did to my parents.
Kevin: It's a nice skill for a chakra but You should know that it's like a passive skill. But if you wish I could just teach you
Adam: Yes teach me sensei
Kevin just put his hands on back of Adam and did something sort of Accupunture kinda thing which made him completely open 1 chakra.
Then Kevin Fischer took him to a cave full of carcasses.
There he took the gall of the 2 horned Snake which had 3 chakras full of poison which is in God stage and the intestines of Poison Dragon which is almost in God Slayer Stage and the Fangs of 7 horned centipede which is in god slayer stage and mixed them with the most poisonous herbs found on the planet and gave it a good mix and forced Adam to swallow .
Adam Felt the poison getting concentrated in the Poison Chakra which Kevin has opened just a while ago. Blood began flowing from all his 9 holes of his body and after suffering the hellish pain for the entire 3 months, He successfully opened The Poison Chakra. With Only Poison Chakra he felt that he could on par fight with Barbarian Stage Fighters and even God type Fighters might feel difficult to fight him.
Kevin was shocked to see Adam getting his poison chakra open within 3 months.
Kevin: Did you Decide What elements you choose for the other 7 Chakras
Adam : Fire, Water, Thunder, Wind, Ice, Dark, Heal
Kevin though expected his answer felt shocked as he mentioned Dark
