The Heaven Lock Technique

Jiang Hao frowned when he saw the person appear suddenly.

The other party's concealed aura was incredibly strong.

Among the many undercover agents, few could surpass this person.

Moreover, their strength seemed as bright as the sun in the darkness.

They were disguised as a Foundation Establishment Realm cultivator.

"A Foundation Establishment Realm cultivator calls me Junior Brother?" Jiang Hao looked at the person. "Do we know each other?"

It was not uncommon for a Foundation Establishment Realm cultivator to address him as Junior Brother, but this person must have known him from way before.

For instance, Senior Sister Xin Yuyue was still in the late stage or peak of the Foundation Establishment Realm. Even now, he addressed her as Senior Sister.

If they hadn't known each other before, Jiang Hao might have addressed her as Junior Sister instead.
