After more than twenty days passed, the wind and waves within the barrier became calm, and the fierce thunder and gale had completely vanished, revealing a pair of silver-white wings.
Using the bones of a Thunder Roc as the primary framework, supplementing with materials from other spirit birds as flesh and blood, and then transforming the power of wind and thunder into feathers.
Thus, a pair of Wind Thunder Wings was formed!
Now, the spirit wings appeared to be complete.
However, in reality, the wind and thunder power within each long feather had only just taken shape and had not yet truly stabilized.
Therefore, the three monsters led by Feng Xi, even though their magical power was already greatly depleted, still forced themselves to pour wind and thunder spirit power into the light barrier, fearing that their efforts would be wasted.
Yet as Feng Xi did this, he felt a bit frustrated in his heart.
He had originally thought that specially exchanging for three drops of Spirit Liquid from other demon cultivators was ample precaution against excessive magical power consumption.
But he hadn't expected that the actual crafting of these Wind Thunder Wings would consume so much more spirit power than anticipated.
Fortunately, judging by the current situation, it seemed barely possible to push through to the end even at the cost of some vital essence.
Otherwise, if the refinement of this treasure were to fail because of this reason, there would be nowhere to buy regret medicine.
Just as this level-nine demon cultivator secretly lamented his luck, he suddenly felt a faint ripple of spiritual energy fluctuation appear in the refinement chamber.
Although the moment was short and the fluctuation was weak, it was extremely pure.
Feng Xi's expression shifted slightly. His icy gaze swept over and finally landed on Han Li, his face darkening.
Han Li's expression changed drastically, and he forced a smile at the demon.
But the demon stared at him coldly, his face devoid of any emotion.
"Hand it over!" the demon said flatly.
"What does Senior want?"
Han Li's expression became even more strained, an unnatural look appearing on his face, and he quietly slipped one hand into his sleeve.
Feng Xi's eyes narrowed slightly, a cold light flashing within them.
Suddenly, without another word, he raised a finger. At its tip, a ball of dazzling white light appeared, flickering between darkness and brilliance.
Standing within the formation, Han Li saw this scene. He was first stunned, but immediately let out a miserable cry and fell backward to the ground.
His limbs twitched uncontrollably, his face turning dark purple, twisted in unbearable agony.
"Hmph! You refuse a toast only to drink a forfeit!" A ferocious look flashed across Feng Xi's face, and he coldly looked at a small bottle that had fallen from Han Li's sleeve. An odd expression appeared on his face. With a single-handed grab, the small bottle instantly flew into his hand.
"The taste of the Wind Spirit Force activating is unpleasant, isn't it? Just now you seemed to have very little spirit power left, yet now you've recovered a considerable amount. It seems there must be some kind of spirit medicine in this bottle. Fellow Daoist Li, were you planning to take advantage of our depleted magical power to recover yours and seize an opportunity to escape?" The Windsplitting Beast glanced at Han Li and said bluntly.
Han Li, at this moment, was struggling to stand up since the demon had stopped his spell. He heard these words and instantly lost all color from his face, looking as if his plan had been seen through.
"You're a bit clever. I want to see what exactly is in this bottle. I've never heard that besides the Ten-Thousand-Year Spirit Liquid, anything else can instantly replenish magical power." Feng Xi looked at the small bottle, casually tossing it in one hand, and murmured.
"I, Wu, haven't heard of such a thing either. But perhaps it might be useful to us right now," said the Venomous Flood Dragon standing opposite, also with a look of curiosity.
At this moment, he and the Turtle Demon were still continuously shooting various colored spells at the bone wings to accelerate the process of solidifying the wind and thunder power. Although they looked a bit better off than the Turtle Demon, their magical power was also significantly depleted. They were merely holding on desperately.
Hearing these words, Feng Xi was slightly stunned, but then something stirred in his mind, and he opened the bottle cap.
A wisp of pure spiritual energy wafted over, assaulting the nostrils!
The demon first glanced into the bottle, then lightly sniffed it with his pointed nose, and a strange expression appeared on his face.
"What is it? What exactly is it?" This time it was the Turtle Demon, who couldn't hold back his curiosity and pressed for an answer.
"Tell them yourself," Feng Xi glanced at Han Li and said flatly.
"Diluted Spirit Liquid made from a single drop of Ten-Thousand-Year Spirit Liquid," Han Li said dejectedly, somewhat reluctantly.
