Ling Feng had been watching from the side without speaking, finding the situation rather amusing.
"Is it really necessary to make such a fuss over a simple boxing match?"
At that moment, the person inside the metal gate, upon seeing the two plastic pieces, pulled open the bolt with a clang, and then the door opened.
It was pitch-black inside, revealing only a deep passageway. After entering, the guard finally spoke, "Walk down the stairs and be careful, it's slippery!"
Lin Xue didn't speak either; she took Ling Feng's hand and moved forward, then they started descending the staircase!
"So it's underground?" Ling Feng became even more curious.
Scenes like this seemed to only appear in gangster movies, where such secrecy was reserved for underground gambling dens. He hadn't expected a boxing match to be treated with such caution.
After a few turns, the two reached level ground, facing another corridor that was too dark to make out any figures.
