At the end of the tunnel, there was a stone door.
On the door, there were sculpted a pair of peculiar monsters.
These were two bird-like creatures, their crested feathers sprouting from their heads, forming the shape of a crown.
Upon seeing someone approaching, their dragon-sized pupils lit up, and the stone sculpture began to move.
"This is an Erstech Bird, the bird of wealth, a legendary mysterious creature said to have the ability to quickly identify and estimate the value of treasures…" The old witch stepped aside, signaling Su Lu to step forward: "To enter the high-end trading session, you must present something that pleases it, and it will open the door for you."
'What a greedy bird…'
Su Lu sarcastically thought to himself, though no change in his expression was evident or could be seen due to his masked state.
"Well... this will do!"
After some thought, he very decisively handed over a stack of silver bills.
"Beep beep!"
