The spirit forging furnace is entirely black, with white flames burning inside, seemingly magical yet strangely odd.
Moreover, when approaching it now, this spirit forging furnace seems to have been fully activated. Beyond its black surface, rows of small letters emitting faint blue light emerged.
"Spirit forging furnace is prepared for low-level boundary spirit mages. With different flames, it refines the spirit power of the spirit mages, thereby strengthening the spirit power and enabling communication with stronger boundary forces, leading to a qualitative improvement in the boundary art."
"The spirit forging furnace can only be used once. Once entering it, it will fully operate. According to the will of the person entering, the flames can be changed from weak to strong."
"Come here, fellow who has a connection with me, act within your capabilities. If you cannot persist, please exit this furnace. Do not be greedy, nor be eager for quick success. Otherwise, you will fail and lose more than you gain."
"Indeed, it is for refining spirit power. It has clearly given a reminder. It seems that the owner of this Shura Ghost Tower is really excellent."
Chu Feng happily said.
"What's so good? It's clearly demonstrating his superb boundary art, making later generations admire him."
"Rather than creating this array, it would be better to leave the wealth behind." Eggman pursed his lips, seemingly not very satisfied with this generous gift.
"Hey, I think this is exactly the master's ingenious intention here. Leaving the wealth is certainly good, but it cannot better test the successors. However, this spirit forging furnace can precisely make up for this point."
"This spirit forging furnace is definitely of great benefit to boundary spirit mages, and it is a benefit of changing one's own strength."
"However, as for how much it can change, it depends on oneself. I have to say, the owner of this place is really brilliant."
But compared to Eggman, Chu Feng was quite content.
"You seem to be quite content with your situation. So, if that's the case, hurry up and enter this spirit forging furnace. The Queen here will see how far you can persist in this spirit forging furnace."
Eggman said with a smile.
"Hey, then just wait and see." Chu Feng smiled slightly and then stepped into this spirit forging furnace.
"Boom" Just as he stepped in, the white flames rushed towards him like a tide, not only surrounding Chu Feng but also fiercely attacking him.
And as described, these flames were very strange. They were flames, but there was no temperature, and they couldn't burn Chu Feng's clothes. Instead, they strangely merged into Chu Feng's body and swept towards his intangible spirit power that was invisible and intangible.
At this moment, Chu Feng could feel that under the attack of these white flames, his spirit power had some changes, being refined. However, the effect of this refinement was not very significant. Even his Shura Ghost Axe, which was always refining his spirit power, was not as good as this.
"Boom" It seemed that sensing Chu Feng's disappointment, the spirit forging furnace emitted another loud noise. The white flames actually changed and turned into gray flames, continuing to refine Chu Feng's spirit power.
"Although it is close to the effect of my Shura Ghost Axe refining spirit power, it is still too weak. Can't you do something more powerful?" Chu Feng shouted loudly.
"Boom" As his words ended, the flames inside the spirit forging furnace indeed changed again, turning into blue flames.
At this moment, Chu Feng couldn't help but frown slightly, but his face was filled with joy.
Because under the blue flames, Chu Feng felt that his spirit power was being rapidly enhanced. This effect had surpassed the refinement effect of his Shura Ghost Axe, but with this refinement effect, Chu Feng also felt a kind of pain, as if countless small needles were stabbing into his brain.
"Finally, it's interesting. Do you dare to be stronger?" Chu Feng shouted excitedly. "Boom!" Just as Chu Feng had hoped, the flames in this spirit forging furnace changed from blue to purple.
"Um"
At this moment, even Chu Feng involuntarily furrowed his brows and clenched his teeth. Then his legs trembled, and he suddenly "plopped" down on the ground, because at that moment when the purple flames changed, his head began to endure extremely intense pain.
That feeling was like several sharp blades piercing his brain one after another, repeatedly and continuously, extremely unbearable.
However, along with this pain came another effect that Chu Feng was ecstatic about. Under the forging of the purple flames, Chu Feng's spiritual power was climbing at an astonishing speed.
"Chu Feng, stop it. This purple flame is already the limit you can bear. That's it. Keep forging like this, your spiritual power will be greatly enhanced."
Egg Egg reminded.
"You're right. This purple flame indeed will be of great help to me. It can polish my spiritual power to an astonishing intensity, and even communicate with the golden barrier power, there's no problem."
"But this requires a very long period of forging. At least a year. You need to forge here day and night for a year. Only then can my spiritual power reach that intensity."
"I can't wait. I don't have that much time. So this time, I can only be eager for quick success and take a risk."
At this moment, Chu Feng's face was pale and he was sweating profusely. But he still resolutely shouted out:
"I want stronger flames!!!"
"Boom!"
As soon as Chu Feng finished speaking, the golden flames instantly emerged, like a pack of fierce beasts, with that ear-piercing roar and terrifying attack, launching the most vicious attack on Chu Feng.
"Ugh ah~~~~~~~~~~~~~~~~~~~~"
Even Chu Feng, who had endured various pains, couldn't help but scream out at this moment. Then he tightly grasped his head and began to roll back and forth in the spirit forging furnace.
Pain, too much pain, it had reached an unbearable level. Just like at this moment, countless tiny cracks appeared on his head, and within those cracks, strange insects were devouring everything.
"Chu Feng, get out quickly, get out quickly. Otherwise, you'll die here."
Seeing that Chu Feng couldn't bear this pain, Egg Egg became extremely nervous and shouted loudly from the bottom of his heart.
"No" However, who would have thought that Chu Feng spat out this sentence with gritted teeth. Not only that, he turned his body and hit the ground with his fists. He actually stood up.
However, instead of stepping out of this mental forging furnace, he sat down cross-legged on the ground.
At the same time, he placed his hands together and made a calming hand seal. Under this unbearable pain, Chu Feng did not choose to retreat but instead chose to face the challenge and continue to endure.
He was adapting to this pain. He had to adapt to this pain. Only in this way could he continue to enjoy the countless benefits brought by that golden flame.
