Passage behind the broken wall, how can the legacy be easily obtained?
On a night more than a month before, the image wall in the secret cave had briefly shown Flower Wine Monk’s bloody message announcing an inheritance behind it before its Photo-audio Gu’s strength ran out and the wall returned to ordinary stone, and only after Jia Fu left and the academy elder’s investigation faded, about ten days later, could Fang Yuan slip back to it. ch. 60
For six days he has worn away at the rock wall with the Moonlight Gu rather than pick and hammer, since tools would carry noise beyond the cave, and by the sixth day he has cut about three inches into a slab as tall as half a man, his green copper primeval essence down to under twenty percent, before he finally kicks a hole through and steps outside to let the stale air clear. ch. 60
Widening the gap by hand, Moonlight Gu, and more kicking, he opens a passage he can fit through, its red-lit walls sloping down out of sight, and before entering he weighs what kind of strength inheritance Flower Wine Monk, who built it to nurture an avenger against the Gu Yue clan, might have left, a righteous kind meant to test character without killing failed claimants, or one of several demonic kinds, some testing the mind, some a plain room of Gu and stones, some lethal on a single misstep, some built as traps to drag a claimant down with their creator, and admits that no one in his prior life had ever learned which this one was. ch. 60
He throws a rock down the passage to test it and hears nothing alarming, then instead of entering scatters rock powder at both the passage entrance and the rock crack outside, slips out to drink and spill wine on his clothes so he smells of it, and returns to the school hostel at midnight as he has taken to doing since first finding the Liquor worm, so his absence draws no suspicion. ch. 60
