Part 6/16:
After 17 days of relentless pumping, the water was finally emptied. The community and researchers could now see what had been concealed for centuries. Descending the narrow, wet stairs, Woo found himself in a vast underground chamber with a floor area of approximately 12,000 square feet—larger than most commercial buildings and with a ceiling soaring nearly 100 feet high.
Inside, the chamber was astonishingly well-preserved, with walls and pillars bearing deliberate tool marks. These marks, etched in perfect parallel lines, pointed to advanced craftsmanship and engineering. The pillars, some as thick as tree trunks, supported ceilings that defied natural formation, hinting at highly sophisticated construction techniques.
