"Boom!"
His Alchemy Ingredients immediately ruined, and his furnace exploded along with the monster core. He was then transported back again to reality.
Alex had gotten surprised by it. He never thought the situation would become like that. Alex took a deep breath to calm his mind before entering the Simulation Room again.
Alex failed every single time. The second time he tried, he thought he had enough preparation. But when he tried to kill the Wind Leopard with his Phoenix Claw. The Wind Leopard dodged him and landed a hit.
Because of that, his concentration on the rest of his ingredients got disturbed, leading to another explosion.
He fought the Wind Leopard again and again before finally succeeded in killing him. But when he tried to merge the rest of his ingredients. The Wind Leopard ruined it again with the last bit of energy from its will.
