After Zi Tianfei explained, Tian Xin and the others finally learned that the plaque of Lingxiao Pavilion was no ordinary object. It was a divine artifact. At last, they could set their minds at ease. Having seen You Ye Heavy Halberd, they knew the plaque couldn't be put into a Storage Ring, which meant it would be easier for Ling Tian to find.
After Zi Tianfei told them that Shangguan Longyin had gone to great lengths to hunt down Ling Tian, they fell into thought, then showed dawning realization. Ling Tian might be Lingyun's son, but he was still just a minor cultivator. Even Lingyun and Ten Thousand Swords Cliff could deal with him, so why would they care so much about Ling Tian?
"Sister Fei'er, you said this plaque isn't ordinary?" Lian Yue's curiosity flared. "Could it have some other purpose?"
"Of course. This plaque is the heart of Lingxiao Pavilion's Guardian Formation." Zi Tianfei spoke as if it were obvious. Seeing the others' confusion, she continued, "The plaque contains a very strange restriction. According to my aunt, it can naturally merge with other restrictions and control the entire formation. With it, the whole formation becomes one seamless whole and can operate on its own, increasing its power by more than double."
"More than double?!" Hu Yao gaped, murmuring, "Every great power's Guardian Formation is already formidable. If its power were doubled, who could possibly break through it?"
"That's right." Tian Xin nodded, her bright eyes shining like the full moon. "I heard that quite a few immortals took part in the siege of Lingxiao Pavilion back then. Even so, they paid a heavy price to break through."
Wen Yan's words left Hu Yao and the others exchanging glances. At last, they understood just how important the plaque was.
