On that day, after Xing Huai'an woke up, he spent several days healing and then set off for a place called Butterfly Flower Valley at the border of Fengg Country.
This was a place discovered by Master White Cloud in his youth.
On the surface, Butterfly Flower Valley was just an ordinary mortal valley, apart from its beautiful scenery, it had no other special features.
In reality, beneath this valley lies a very deep cave, with a Tier Two High-Grade Spirit Vein.
In those years, before Master White Cloud formed his Core, he secluded himself here for cultivation.
After forming his Core and gaining fame, the Tier Two High-Grade Spirit Vein was no longer very useful to him, and being within Fengg Country, he did not open it up.
Instead, he sealed the place and stored some treasures here as a Secret Vault, to serve as a backup.
In case one day something unpredictable happened to White Cloud Immortal City, this place could also serve as a retreat.
