"I can't say for sure. But it must be at least a Heavenly Level Spirit Weapon." Daoist Yun responded, "Therefore, let's be very careful."

On their approach to the place, they saw a gigantic Red Roc along with twelve black Rocs on the water's surface just beyond a dark mist. There were also people standing on the back of those flying beasts.

"Oh, the emperor and his entourage are already here. Daoist Yun, please ride it toward them." Emperor Lin said.

After a few minutes, their black Roc landed on the surface of the overflooded water. 

Hua Emperor greeted him clasping his hand, "Greetings, Brother Lin!" Then he took a step forward and appeared standing in front of Patriarch Lin.

Laughing loudly, Patriarch Lin responded, "Brother Hua! It's nice meeting you again. Come, come, let's have some drinks like last time." 

Daoist Yun waved his hand and a portable roundtable with three chairs around it appeared standing on the back of the Black Roc.
