Previously, when Duan Ling Tian went to Hidden Fog City, he had already obtained most of the ingredients needed to refine the Royal Grade Spirit Weapon.

Along with the Ink Steel, the refining material he had obtained in the Martial Emperor's secret treasure that was left behind by Martial Emperor Qing Feng, he could now refine the Royal Grade Bow and Arrow.

"I wonder how long I spent cultivating this time." Duan Ling Tian did not rush to craft the Royal Grade Spirit Weapon. Only after he had walked out of the wooden house and checked the Killing Formation he had set up in the surroundings that he finally left, feeling at ease.

The Killing Formation was set up when he and the two women built the house previously.

The Killing Formation was potent enough to kill a person below the Seventh Level Martial Monarch Stage. Even if someone above the Seventh Level Martial Monarch Stage but below the Martial Emperor Stage entered the Killing Formation, he would be severely injured if not dead.
