And right below this small mountain.
A spacious, silent concrete labyrinth.
Apart from the staff that update supplies and equipment every few years, the last guests it welcomed were fifty years ago. The underground safehouse, like an ancient tomb, still shows no signs of life. Only a few mirrors located in the center of the labyrinth have dense inscription arrays, vaguely forming a massive design.
Just in the center surrounded by the mirrors, a crystal ball suddenly lights up, five different beams of light emerging from it, projected onto the surrounding mirrors, reflecting five indistinct, shadowy figures.
These five figures are all Elves.
"We must seek revenge."
A deep voice said, "But under the World Tree's sphere of influence, it's impossible for us to succeed. The Yinmen Household has, from who knows where, found ultra-efficient computer technology from the previous era, and completed the missing computation modules of the World Tree."
