Lin Yan, a talented fencer, watched his biological father jump into the furnace for him on the day he fell from the clouds into the abyss of Rust City.
He thought that the only thing left in his life was to die together, but he was rescued from the brink of death by a mute with a useless hand.
One is a scheming beauty who has been abandoned by the world and regards everything as a bargaining chip.
One is a silent beast with unique skills who is swallowed by the darkness, only guarding the only softness in his heart.
The "earth fire" roared in the underground arena, and the legendary "Ghost Engine" reappeared.
Lin Yan pointed to the heart that could ignite the night and made a cold deal to Rusty Bones: "Your hands, my brain. Let's work together to win the championship and save your sister."
He thought it was just a big gamble to take advantage of each other.
Little did he know that from the moment Rusty Bone blocked the fatal steel pipe for him, the gears of fate had been welded to flesh and blood.
When the "glass tower" symbolizing class overturned in the fire, Rusty Bones gestured in sign language before the explosion:
"You teach me how to speak, and I'll teach you how to fly."
Lin Yan broke open the city's communications and shouted towards the upper city:
"Do you hear that? This is my bones burning!"
