Long Jingxiao

The Longye Sect's cultivators had just completed sealing another breach between the Netherworld and the human realm. The demonic entities had been destroyed and the rift temporarily sealed, but the ancient formation that had held the boundary between worlds for centuries was almost completely destroyed.
According to established procedure, masters of the Third Grand Order arrived at the scene to determine the cause of the incident. While the elders discussed what they had seen with the Longye cultivators, one of the young masters silently examined the remains of the seal.
She studied the barely discernible lines for a long time, after which she said quietly:
— There is an extra symbol here.
Several spellcasters exchanged glances.
— Most of the printing was destroyed. How can you be so sure?
"The basic structure has been preserved. This is enough to understand what it was like originally. This sign does not belong to the original formation."
Her words were heard by the head of the Longye Sect, Long Jingxiao, who was standing nearby.
The elder of the Order of Seals came closer, carefully examined the remains of the formation, and after a few moments nodded.
— True. The seal was altered long before the breakthrough. Someone deliberately disrupted its structure.
Long Jingxiao silently looked at the destroyed symbols.

• So it's not an accident.
  Having received confirmation, he ordered his men to begin an investigation and soon left the scene. For him, this was just one of many tasks accomplished. He never asked the young craftswoman's name.
  By evening, the delegation returned to the Xuanwen Sect. A servant was already waiting for the girl at the gate.
  — Young lady, the head of the order asked you to come to him immediately upon your return.
  She nodded calmly. To most cultivators, she was simply a talented young master of spiritual seals. But outside the sect, she was known differently—as the daughter of the Xuanwen clan leader, who was to personally report the results of the investigation.
