Ling Pengyun was immediately startled upon hearing this.
Bei Shan Zhenren's map had made no mention of such a treasure within this secret realm.
The Profound Heaven Spirit Pool could produce spiritual objects that aided cultivators in breaking through their realms. For example, Third Rank Profound Heaven Water could assist cultivators in breaking through to the Golden Core realm.
A Quasi Fourth Rank Profound Heaven Spirit Pool could nurture one portion of inferior Nascent Soul Spirit Object Profound Heaven Water every three thousand years, raising a cultivator's chance of breaking through to the Nascent Soul realm by half a tenth.
Although half a tenth was not a high probability, to most cultivators attempting Nascent Soul Formation, it was something that could be sought but never obtained.
If it were placed in the Northern Wilderness Cultivation World, it would be enough to draw all the Nascent Soul cultivators into a scramble for it, setting off a bloody storm.
For a moment, Ling Pengyun seriously suspected that Bei Shan Zhenren, who had already become his Lifelong Ally, had intended to swallow that Quasi Fourth Rank spirit pool whole and had therefore concealed its existence.
With a hint of interrogation in his tone, he immediately questioned Bei Shan Zhenren, who was still concealed in the shadows in case anything unexpected happened.
Yet Bei Shan Zhenren knew nothing of this matter. Even his earlier claim to Ling Pengyun, before entering the secret realm, that there was something here that could aid Nascent Soul Formation had been a lie, merely intended to persuade Ling Pengyun to come along.
Moreover, Bei Shan Zhenren was extremely decisive and directly swore a Heavenly Dao Oath with his cultivation.
That attitude dispelled Ling Pengyun's distrust of Bei Shan Zhenren, and the rift that was about to form between them
