System Bestows me with Immortality, Living on to Eventually Become Invincible

"Moo!"

Black Bull held up a cultivation manual and bellowed at Chen Xun, "Moo moo!"

"What's up, Bull?" Chen Xun was examining a sea chart, his gaze following the sound.

Black Bull was holding a body-refinement manual. Although it was a heretical method, it proved that Da Li at least had orthodox body-refinement techniques.

"Hmm." Chen Xun's eyes narrowed slightly as his divine sense probed the manual.

This body-refinement technique actually used the flesh and blood of immortal cultivators to strengthen oneself. No wonder those two weren't completely obliterated by the attack; their skulls just cracked open.

"But this heretical method clearly has issues. Even reaching the Elemental Infant phase would be problematic."

Chen Xun shook his head with a smile, "I saw a place on the sea chart, a forbidden area in the West Sea. We might find what we need there."

Black Bull nodded dumbly. He destroyed the heretical manual since Big Brother said it was useless, so there was no point in wasting time studying it.

Little Chi was still fiddling with spirit stones, using his divine sense to count them. He even kept his flaming tail behind him, afraid something on the island might sneak up and attack.

"Xun, Brother Bull, with so many cultivation resources, we don't need to take any risks."
