Feng Yun and the old man sword saint spent a few hours and finally laid a guardian formation around the shop building. It was strong enough to hold against a Peak Great Saint Realm cultivator. However, it can't stop them for too long, nor can it trap or injure a strong great saint realm cultivator like the old man sword saint.
Although the old man was a great saint, his combat power was the best among great saints; it was all due to his mastery of the sword.
However, it was pretty good; there are not many strong great saint realm cultivators in Black Plain City. Feng Yun had only one enemy he needed to guard against in the Black Plain city, and that was the leader of the Black Wolf Guild.
After the formation had been set up, Feng Yun opened the business again.
The night air in Black Plain City was heavy with dust and heat. Lanterns burnt dimly along the crooked streets, their light shivering against the breeze.
