Gu Youyou looked at the stone disk and deduced that all she needed to do was to find a Life Gate immediately!
Kun is Death, Gen is Life, Li above and Kan below, Kun and Xun signify shoulders, Zhen and Dui mark the central path, while Gen and Qian are situated to the left and right respectively.
"Found it!" exulted Gu Youyou, her eyes shining with excited light. She rotated the stone disk to position the Gen trigram at the Life Gate.
Soon, a rumbling sound echoed through the tomb chamber.
But contrary to Gu Youyou's expectations of the tomb door opening, the top of the tomb chamber started making increasingly loud thumping sounds, as if it could collapse at any moment.
As the noise grew louder, chunks of stone mixed with dust began to fall, and the chamber's walls started to show web-like cracks!
Gu Youyou was terrified!
What was happening? She had clearly found the correct Life Gate.
Suddenly, Gu Youyou had a realization.
