Myriad Fathom Sword Cavern.
Ever since Zhou Chun confirmed he could endure the Geng Metal Power within the Myriad Fathom Sword Cavern, he embraced the life of a relentless cultivator.
He spent the majority of the year inside the cavern, absorbing and refining the Geng Metal Power to purify his own Mana.
Only when his body signaled exhaustion did he temporarily leave for a few days to rest in the Secret Mansion outside.
During his rest days, Zhou Chun also engaged with other cultivators in the Secret Mansion like Hou Bin, gaining a wealth of useful information.
According to Hou Bin, Tai Geng Divine Venerable and his incarnations rarely come to this Secret Mansion to cultivate, merely retaining ownership of it.
Cultivators like Hou Bin in the Secret Mansion are mostly marginal figures from their own Sects, with little chance for advancement there for various reasons.
