The main hall in the middle of Yu Residence was an eye-opener for Wu Qi. Unlike the other palaces in Great Yu, it was very strange in appearance. The hall that was constructed with big, dark rocks looked like a bull's head with many horns. It had a total of eight pointed cornices, and was encompassed by a ring of three hundred and sixty huge stone pillars, each of which was carved with countless patterns of ghosts and deities. Naturally, a fire bowl was placed atop each pillar, where pale-green flames rushed up to a height of tens of feet.
