Huo Yun nodded, opened her mouth wide and swallowed all the pills before saying, "Thank you, Master. Well, I was just overexerted, but it's nothing serious."

Seeing this, Lin Xiuyuan put aside his worries and asked curiously, "To what extent can you activate this Black Flame Eye?"

"I was only able to draw upon a trace of the ancient treasure's power after breaking through to the Foundation Establishment stage, and I can't even say I activated it. I only used the connection of my inherited bloodline, at the cost of a large amount of mana and blood essence, to draw upon its spiritual power and form a binding and restricting force. For a mid-Foundation Establishment cultivator, a rogue cultivator like the Golden Mirror Master can at least restrict him for ten breaths. That's basically it."

"For those in the late Foundation Establishment stage, it can only create some kind of binding effect. I estimate that the binding effect is not very satisfactory and the duration is not long, probably only two or three breaths at most."

"If you encounter any overly mysterious magical artifact that can resist the power of confinement and restraint, then the suppressive effect of the ancient treasure's spiritual power will be even lower."

Huo Yun told the truth.

Lin Xiuyuan nodded, a hint of satisfaction and joy flashing in his eyes. Now that Huo Yun had such a trump card, it was truly excellent news, and its helpfulness was self-evident.

Although it was just a simple activation of a fraction of the ancient treasure's spiritual power, it was enough to create a binding force on a mid-Foundation Establishment cultivator, and the effect lasted for quite some time. This meant that by joining forces, they already had the ability to fight against cultivators of higher levels!

After putting Huo Yun back into his spirit beast pouch to allow her to heal slowly, Lin Xiuyuan took the Golden Mirror Master's Qiankun Pouch with a hint of joy and immediately probed it with his divine sense, his face filled with anticipation.

"I wonder if there is any method to protect me. That spell is truly mysterious and strange. If I could learn and master it, it would definitely greatly enhance my combat power..."
