The only way from the secret room in the garage to the underground laboratory was via this elevator. With the power out, the carriage was suspended ten meters above the laboratory, making it necessary to escape the sealed carriage to reach the bottom of the shaft.
Feng Jue used the golden thread to cut a hole in the ceiling. He then grabbed the edge of the carriage and climbed out through the opening.
The golden bracelet on his wrist shot out golden threads, piercing through the carriage and anchoring itself securely. He then jumped down into the elevator shaft.
The golden thread was a nanometer-sized tube, sharp on one side and featuring high friction on the other. He had used the sharp side to cut the elevator carriage, and now, needing to secure things, he switched to the friction side.
The sharp side couldn't tie things up; it would only cut them.
