At this moment.
Ling Pengyun gazed at the four Golden Flood Dragons before him, whose Flood Dragon Bloodlines had all reached the Fourth Grade, his eyes gleaming brightly.
He then asked the four flood dragons.
"Now that the strength of your Flood Dragon Bloodlines has reached the Fourth Grade, are you confident in charging for Golden Core on your own?"
Without any hesitation, the four Golden Flood Dragons immediately nodded. They were brimming with confidence.
Seeing this, Ling Pengyun smiled and placed them into the Storage Bag at his waist. He sent them to Cloud Stepping Valley in the Cloud Stepping Ridge territory of the White Cloud Mountain Range, where the Lightning Guiding Tribulation Crossing Grand Array had been set up, and let them enter seclusion to charge for Golden Core.
During this time, Ling Pengyun chatted with Ling Li Hu, the genius Beast Tamer and valley master here, about the progress of perfecting the "Thunder Winged Shadow Tiger Mutation Method."
According to Ling Li Hu, he was confident that within a hundred years, he could truly perfect the Thunder Winged Shadow Tiger Mutation Method to mid-tier quality.
This would give ordinary Winged Shadow Tigers a one-percent chance of mutating through this method. Even if they failed, they would suffer only minor injuries and would recover in less than several decades.

And this Thunder Winged Shadow Tiger Mutation Method had gradually begun to bring benefits to the Ling Clan.
