Two days passed in the blink of an eye.
Since the assault that day, Ling Chen had strengthened the security forces around the tunnel, with Beison's team monitoring 24/7. Furthermore, Ling Chen had moved directly into the shopfront to prevent that woman from launching another sneak attack.
During these two days, Ling Chen sped up the excavation progress, reaching over forty meters deep. If all went smoothly, they'd likely discover Ling Gengqiu's tomb in about a day. On this day, Ling Chen stood outside the tunnel, supervising his subordinates' work. Watching bucketfuls of soil being hauled up, Ling Chen felt an excitement he couldn't suppress.
Knock! Knock! Knock!
At this moment, a sudden knocking sounded from outside. Ling Chen turned to look at the rolling shutter door, sensing something was amiss. They had agreed beforehand that if there were knocks of three longs and three shorts, it meant their own people had arrived.
"Beison, who's out there?"
