Situ Xuanming introduced himself the moment he saw Yunxi:
"I am Situ Xuanming, an elder of the Spirit Formation Pavilion and a ninth-grade formation master. It is truly my honor to meet Fellow Daoist Ranxi in the Ancient Battlefield."
After hearing his polite words, Yunxi returned the greeting with cupped hands.
"I heard Cao Yi mention Fellow Daoist Situ before. Learning that you are a Grandmaster of the Formation Dao, it is Ranxi's honor to meet you."
Hearing Yunxi's flattering words, Situ Xuanming rubbed the small black mole on the tip of his nose and got straight to the point.
"We are on a battlefield, so let us not waste time exchanging pleasantries. I came here to see the special rune Cao Yi spoke of—just how special it is, that it can even make up for the flaws in the formation disks we refine."
After speaking, he stared fixedly at Yunxi, seemingly wanting her to demonstrate it on the spot.
Cao Yi, standing to the side with his face full of black lines, looked at Ranxi, whose expression had not changed, and immediately cleared his throat.
"Venerable Ran Xi, Senior Situ is a little impatient. After hearing what I said, he was eager to witness the power of the runes you draw, so..."
Yunxi nodded after hearing this and said with a smile, "I have already read the jade slip you gave me before. I have corresponding upgraded runes for all the runes needed for the formation disks you refine. Demonstrating them for Fellow Daoist Situ is no problem, but can you be sure that the formation disks you refine can bear the power of the runes I draw?"
With one simple sentence, she kicked the ball right back to them.
Cao Yi had indeed considered this issue after returning.
