The immense power of the Eighth Grade Immortal Flame Starfield was fully manifested at this moment. In just a brief span, the Prime Iron seamlessly fused with the Azure Veil Blade. Joe Di didn’t even need to employ his own forging techniques—he could sense the Azure Veil Blade advancing automatically, upgrading on its own.
“Take care of yourself. We'll work hard to cultivate here.” Moria Lane knew that with her current cultivation, following Joe Di would only become a burden to him. The only thing she could do was focus on improving her own strength in this place.
Joe Di took out another ring and handed it to Moria Lane. "Inside are cultivation resources for all of you. When I have the strength to protect myself, I will return and take you all to Cauldron Haven Free Immortal City."
At this moment, Joe Di was unable to take Moria Lane and the others away. Although he had the True Spirit World, the cultivation conditions here were far superior.
If he took Moria Lane and the others away, all they could do was remain in the True Spirit World, with nothing else to occupy their time.
Regrettably, on his next outing, he would not be able to carry the Azure Veil Blade openly. If he could, the blade’s advancement would accelerate even further.
Boom boom boom! The sixth wave brought eighty-one arcs of lightning tribulation, making Joe Di's immortal essence churn like boiling oil throughout his body. Unfortunately, the tribulation was not strong enough to further advance his body refinement.
His cultivation had completely stabilized at the first rank of Grand Celestial, but this time his spirit sense did not advance, remaining at the peak of Spirit Sense Level Six.
This made Joe Di anxious. According to his cultivation level, every breakthrough should bring an advancement in spirit sense. If he couldn't reach Spirit Sense Level Seven, it would be dangerous for him to visit Cauldron Haven Free Immortal City.
Spirit Sense Level Seven was a completely different realm than Level Six. With Level Six, his divine sense escape technique couldn't elude an Immortal Emperor, but with Level Seven, most Immortal Emperors would be unable to catch him.
Joe Di didn't rush to leave. He took out several pieces of Violet Heaven Silk and began extracting the gray-violet thread once more.
He still hadn't found a way to fully purify the gray-violet thread. Now, having just reached the first rank of Grand Celestial and with his spiritual sea expanding, he hoped to use the gray-violet thread to advance to Spirit Sense Level Seven.
After purifying a drop of gray-violet thread, Joe Di immediately swallowed it. He couldn't store the thread at all—if he waited more than half a breath, it would dissipate.
Boom! A wild surge erupted in Joe Di's spiritual sea, instantly expanding it by a level, with Dao patterns rippling throughout.
Seeing no signs of advancement, Joe Di didn't hesitate to purify a second drop of gray-violet thread...
Then came the third drop, the fourth drop...
Poof! When Joe Di swallowed the tenth drop of gray-violet thread, he spat out a jet of blood, his face pale as paper.
He could not continue swallowing the gray-violet thread. Without any medicinal herbs to neutralize it, further consumption might not only prevent advancement but could collapse his spiritual sea.
His spiritual sense forging technique ran madly, his spiritual sea felt as if it were exploding, rumbling continuously, and blood flowed from both his ears and eyes.
Joe Di was terrified—he realized he had been too impatient. Cultivation should proceed naturally; even if he wanted to improve his strength, he couldn't force it like this.
