Where's Zhang Fei? [XVI]

There was a cliff on one side of the square, below which was the central main cave of the mine. The cliff was five or six hundred meters high from the bottom of the cave. On the other side of the square was a tall stone wall, on which dozens of huge caves were excavated.

There was a huge glowstone inlaid above the entrance of each cave, each of which was several times larger than what Fei dug up, and the polishing was irregular. The square was illuminated very brightly by these several huge glowstones, but it was not dazzling.

With the light of the glowstone, it could be clearly seen that there was a huge black ant lying there in the square. This black ant was more than ten meters in height and more than thirty meters long.
