Bab 217: 137 Advancing to Core Formation_1

Ten years went by swiftly.

In a valley surrounded by mountains on three sides, there stood a three-story cyan pavilion with the words "Qingmei Pavilion" inscribed on the signboard.

In a secret chamber, Shen Long was seated on a red cushion, his eyes tightly shut, his body enveloped in a red glow.

In front of him were placed three porcelain bottles and a cyan jade box, which was covered in dust.

After a while, the red glow surrounding Shen Long dissipated, and he opened his eyes, exhaling a breath of stale air.

"After ten years of refinement, combined with four Core Formation spiritual objects, it definitely should be possible,"

Shen Long muttered to himself.

He had been in closed-door cultivation for ten years, tempering his mana in order to make it purer, all to prepare for Core Formation.

When Shen Long introspected with his Divine Sense, he could see a miniature red lake in his dantian, representing his mana.
