The Underworld Emperor Suppressed by the Four Strongest Swordsmen

An unexpected event happened in the sky over Zhaoge City.

Bu Qiuxiao looked at the cloud where the Center Sect Master was and said calmly, "Sorry, Immortal."

Having said that, an ink-stone flew out of his sleeve, growing in size many times over under the sunlight, shadowing a sizeable area outside Zhaoge City.

The ink-stone looked ordinary, with a dim color; it had the dragon figures on its surface, with a large dragon tail extending from it.

This was one of the four guardian treasures of the One-Cottage House: the Dragon Tail Ink-Stone.

Seeing this, Liu Ci felt a bit surprised. The One-Cottage House had always been friendly with the Center Sect, but Bu Qiuxiao was about to attack the Old Dragon.
