"The Inheritance Cavern — from the name alone, it sounds like quite the treasure trove," Chu Feng remarked.
"That's right. At the time, our Starfall Sacred Ground's Patriarch and that elder from the Nine Profound Sect thought so too."
"As everyone knows, the Upper Realm of the Great Thousand is filled with countless ruins. But if word were to leak out and reach the Chu Heavenly Clan, any such ruin would become their property."
"To be honest, our Patriarch had his own agenda. Naturally, he hoped to obtain the treasures within the Inheritance Cavern."
"So our Patriarch and the Nine Profound Sect's elder decided not to leave. The two of them stood guard at the Inheritance Cavern year after year, trying every method they could think of to break through the entrance, but none of them succeeded."
"Eventually, the Nine Profound Sect's elder even went and brought back the Sect Master of the Nine Profound Sect himself, yet even he couldn't open that Inheritance Cavern. But you must understand — the Nine Profound Sect is a dominant power in the Nine Profound Upper Realm, and its Sect Master is a bona fide Martial Ancestor realm expert," Xia Yun'er explained.
"In that case, the Inheritance Cavern may have been left behind by an ancient powerhouse. Otherwise, it wouldn't have been so difficult to crack open," Chu Feng mused.
"No, that's actually not the case. The Inheritance Cavern and the ruins in Pingshan Gorge, while old, are nowhere near ancient. From the time our Patriarch discovered them, they were only a few tens of thousands of years old at most," Xia Yun'er said.
"That recent? Which powerhouse left them behind? Was there ever a conclusion?" Chu Feng asked.
In truth, Chu Feng already had his suspicions. The person he suspected was the Arrow Dao Ancestor.
Chu Feng was thinking that it was most likely left behind by the Arrow Dao Ancestor, which was why he asked in such a manner.
However, the Sect Master of the Nine Profound Sect was also a Martial Ancestor-level powerhouse, and even he couldn't break open that so-called Inheritance Cavern.
If it truly was left behind by the Arrow Dao Ancestor, then the Arrow Dao Ancestor appeared to be even more formidable than Chu Feng had imagined.
"There was no conclusion, but the Inheritance Cavern eventually opened on its own," Xia Yun'er said.
"How did it open?" Chu Feng asked.
"It opened automatically," Xia Yun'er said.
"Automatically?" Hearing this, Chu Feng was somewhat surprised.
"It really did open automatically. Though it opened, neither our Patriarch nor any of the experts present could enter. Later, it was discovered that only the younger generation could go in," Xia Yun'er said.
"Only the younger generation?" Chu Feng was startled once more.
"That's right. Not only could only the younger generation enter, but they also had to be Dragon Mark Royal-cloak Spirit World Masters. Otherwise, there was no way in."
"Furthermore, the number was limited. Only ten people could enter each time," Xia Yun'er added.
"Did they find anything worthwhile?" Chu Feng asked.
"They did. Eventually, our Starfall Sacred Ground and the Nine Profound Sect each selected members of the younger generation to enter the Inheritance Cavern."
"They later discovered that simply entering the Inheritance Cavern didn't guarantee you'd receive an inheritance. To gain any benefit, you had to solve the trials inside, and each trial's puzzles were almost always different. The only thing that could be confirmed was that every challenge was related to Spirit World Masters."
"And the Inheritance Cavern opened once every hundred years."
