Xuanzhi explained to Dongfang Yuejian beside him:
"When Brother Taiping and I first came in, we had both concealed our auras, so this Demon Snake never even noticed our presence."
"But just as we sensed Gu Yu descending into the Underground River Passage, the Rock-Armored Demon Serpent not only awoke on its own, but also began sucking up water from the Earth Vein Underground River to strengthen itself."
"Seeing this, Brother Taiping and I were about to step forward and stop it, but unexpectedly, hundreds upon thousands of Bloodsucking Bat Demons suddenly flew out from inside the Karst Cave."
"Though these Bat Demons were ordinary in combat, they could drain a great deal of a cultivator's qi and blood in an instant. With no other choice, Brother Taiping and I could only join forces to clear them out first."
"Otherwise, when we fought that Rock-Armored Demon Serpent, those Bat Demons would have been a major menace."
After hearing Xuanzhi's explanation, understanding immediately dawned on Dongfang Yuejian's face.
Gu Yu, beside her, asked in confusion:
"Could it be because of me again?"
At his words, Xuanzhi looked at Gu Yu in some puzzlement and asked:
"Benefactor Gu Yu, what do you mean?"
Gu Yu then briefly recounted to Xuanzhi what they had encountered in the Underground River Passage.
When Gu Yu finished, Dongfang Yuejian also frowned and said:
"Judging from what the Catfish Demon said, it does seem that bringing Gu Yu in here lifted some sort of restriction within the Earth Vein Underground River."
Xuanzhi nodded thoughtfully and said:
"There does indeed seem to be a connection."
Hearing this, Gu Yu said with some self-reproach:
"Upper Immortals, had I known this would happen, I shouldn't have come down."
Xuanzhi smiled and shook his head.
"It's no matter."
As he spoke,
