It seems like something came to mind.
"Back then, the matter of the Blood Demon Sword Lord indeed involved the Saint Master of our Nine Yang Sect."
"However, it was merely a personal enmity between the Saint Master and the Blood Demon Sword Lord."
"There was quite a feud between the Blood Demon Sword Lord and the Saint Master's great-grandmaster."
"And the Saint Master is the disciple's grandson of that great-grandmaster."
"Thus, he naturally had no choice but to act."
"A few months ago, the Saint Master informed me."
"The Blood Demon Sword Lord appeared within the area of influence of the Nine Yang Sect and was attempting to break through the Divinity Transformation Realm, which gave him quite a shock."
"But immediately after, he was also delighted."
"Because his disciple-grandson had a chance to avenge the previous grievances."
"Moreover, our Saint Master later pushed the matter onto the current Soul-locking Sect Leader, letting them deal with each other."
