How exactly can we prove his identity?

Then Lu Li suddenly said, "Can Sword Eleven, or the Hundred Birds Paying Homage to the Phoenix Spear, prove it?"

"Hmph! All disciples of Ghost Valley can do it, who exactly are you?" Yuan Tiangang was furious, feeling that Lu Li was toying with him!

This is awkward; he really has no way to prove his identity.

“Lu Li’s ancestor had a divine sword that accompanied him, named Tianwen. Do you have one?” Yuan Tiangang then asked.

"......."

Yes, it exists, but it's outside the void, forming the Immortal Slaughtering Sword Formation, which also suppresses the Heavenly Dao!

Seeing Lu Li's embarrassed expression, Yuan Tiangang immediately snorted coldly: "Hmph, just as I expected!"

"Those skilled in the Ghost Valley Observation technique shall die!"

Then, Yuan Tiangang drew his sword again and thrust it at Lu Li with great speed.

Lu Li had no choice but to dodge, since she was a disciple of Ghost Valley and he couldn't bring himself to kill her.

The two began to fight, and Lu Li was forced to retreat continuously, facing constant danger.

Because at this moment, Yuan Tiangang was using Sword Eleven, which had powerful attack capabilities and terrifying speed.

"By the way, do you know that Sword Eleven has a twelfth move?" Lu Li suddenly remembered something and immediately asked.

Yuan Tiangang was stunned for a moment, then said, "You know about Sword Twelve?!?"

Lu Li mentally scoffed, "Nonsense, Sword Twelve was created by me."

"The twelfth sword is named 'Fleeting Beauty, Ephemeral Bloom,' or 'A Moment of Splendor'? Is that correct?"

Now it was Yuan Tiangang's turn to be shocked!

Guigu has now taken in two inner disciples, one of whom will inherit Guigu and become Guiguzi.

The other one is the protector!

Yuan Tiangang was the protector of this generation, and apart from him and Wang Tong, no one knew the name of Sword Twelve.

"You...you are really the ancestor of Lu Li?" Yuan Tiangang asked in a trembling voice.

Lu Li nodded, but felt extremely frustrated.

Damn it, how could someone as dignified as Guiguzi need a sword move to prove his identity?
