"Up...up...down...down..."
A level 17 Flesh and Blood Train was parked inside a cage inlaid with hundreds of thousands of human faces on the wall, and the two giant tentacles extending from the Flesh and Blood Train were rapidly scanning each face.
"9 up, 3 down."
"And the number 1892 etched on the ground, which means the correct sound frequency should be 11352 Hertz."
The boy sitting inside the train cabin laughed.
"Not too difficult, kind of stress-free."
He thought he ought to be the fastest, without a doubt, and it seemed sure that he would smoothly proceed to the third level. Whether he'd be first or fifth was another question.
Only the top five could enter the third level.
The next moment—
"Beep beep beep..."
As his Flesh and Blood Train emitted a piercing sound, all the faces on the wall closed their eyes, and the wall in front slowly opened, revealing a train tunnel.
