The big man licked his lips and said excitedly, "These must be second-grade, right? I didn't expect you to have such things in your place!"

"Don't just look at this, take a look at spiritual weapons, skills and so on. I feel those should be more suitable for you."

The big man looked at the corresponding names on each scroll and couldn't help getting excited.

"Mountain-Breaking Fist, a third-grade spiritual skill."

"Bull Power, a third-grade spiritual skill."

"Xuan Yang Gong, a third-grade technique."

…

"Ice Cold Art, a fourth-grade technique."

The big man looked at them one by one, and in the end his face began to turn red.

"The lowest grade of the skills and spiritual techniques here is actually third grade!"

Looking at the big man's shocked expression, Gu Yuan felt very satisfied. This was exactly the effect he wanted.

"Feel free to look around. We only have so many items on the shelves right now. If you need anything, just let me know. Each item has a faint glow on the outside. Do you see that?"

Gu Yuan pointed at the faint light and said, "That's the aura shield protecting the item. Don't try to break it, or you'll regret it."

The big man was stunned, then took a step back. Although he had no intention of doing anything bad, he was still frightened by Gu Yuan's tone.

Gu Yuan no longer paid any attention to him. He lay behind the counter calmly, squinting his eyes and thinking about something.

The big man stood in front of the iron frame, staring at the items on the armor.

After a long time, the big man gritted his teeth and seemed to have made a difficult decision.

He walked to the counter and said to Gu Yuan, "Boss, what can I exchange for the Fire Yuan Gong and Fire Yuan Palm?"
