To pass the Wind Tribulation.
Failing the Wind Tribulation meant direct dissipation of the primordial spirit.
In the case of direct primordial spirit dissipation, the body remaining was a rare occurrence.
An immortal physical body, capable of living through endless years, might, after the death of its primordial spirit, spontaneously generate another soul.
Primordial spirits could possess other bodies and thus live on.
When the primordial spirit dissipated, the physical body, under the right conditions, could naturally nurture another primordial spirit on its own.
Primordial spirits nurtured this way were typically malicious towards the world.
They would actively, or passively, attempt to destroy this world.
Calling them "demons" would not be an exaggeration.
The exact principle was unclear, but in reality, it was so: often, a soul reborn from a body was filled with malice towards the entire world.
In the long history of this cultivation world, the appearance of demons was not uncommon, causing a certain amount of destruction to this world.
Those who had passed the three tribulations, with their magic, physical body, and primordial spirit perfected, naturally could not stand by and let this happen.
Thus, they established an organization with the intention of dealing with these demons and eradicating them.
Elder Cheng Fu, though not a True Immortal, was a Half-Immortal.
However, within such an organization, True Immortals occupied the top tier of power, not personally intervening in everything, but acting as leaders.
The Half-Immortals, led by True Immortals, were the main force of this organization and the primary force for clearing out demons whenever they appeared.
Therefore, the information previously received was precisely to notify Elder Cheng Fu.
Daoist Taixu, a Half-Immortal who had passed two tribulations, attempted the Wind Tribulation but failed. His primordial spirit had been destroyed by the Wind Tribulation.
However, through detection by True Immortals from an infinite distance, Daoist Taixu was not truly dead; he was still alive.
His primordial spirit was dead, yet he was alive, leaving only one explanation: another primordial spirit had taken over Daoist Taixu's physical body.
Or rather, Daoist Taixu's body had nurtured another primordial spirit.
This signified the emergence of another demon.
Elder Cheng Fu had to eliminate this demon.
If he refused to obey the command of the True Immortals, the consequences would undoubtedly be dire.
It was precisely for this reason that Elder Cheng Fu sighed, lamenting the troubled times, leaving him no free time at all.
Of course, Elder Cheng Fu spoke of "troubled times" rather than a life-or-death crisis, indicating that he had some confidence in this mission.
Elder Cheng Fu and Daoist Taixu, both Half-Immortals who had broken through two stages and passed two tribulations, theoretically possessed similar combat capabilities. A battle between them, evenly matched, could lead to death.
But this was the potential outcome of fighting the living Daoist Taixu.
It was not the outcome that could result from fighting the current Daoist Taixu.
Elder Cheng Fu had repeatedly followed the commands of True Immortals to participate in demon-slaying battles. If every demon possessed the strength of their former selves, Elder Cheng Fu would have died countless times over and would not be living so leisurely now.
In reality, demons, as new souls born from their original bodies,
compared to old souls, while new souls originated from the physical body, their control over that body was vastly inferior to that of old souls.
At the Half-Immortal level, even a slight difference in control over the physical body could reveal a flaw, which could then be exploited for attack.
How much more so for demons with such a vast difference in control over their physical bodies?
For individuals like Elder Cheng Fu, who had truly broken through the primordial spirit and magic power stages through their own strength, these beings called demons, with their innate destructive consciousness towards the world, and new souls born from their physical bodies, possessed extremely poor control over their physical bodies and their own magic power.
To the extent that he could spot flaws with a single glance.
Then, he could devise all sorts of plans based on these flaws, leading to an overwhelming victory against demons whose magic power and physical body levels were the same as his.
Therefore, in Elder Cheng Fu's view, this mission was not a life-or-death crisis.
It was merely an ordinary mission, in these troubled times...
At this moment, Elder Cheng Fu did not yet know what he would face.
Thus, full of confidence, he directly ascended in a rainbow light and departed.
Elder Cheng Fu, as a Half-Immortal who had passed the Wind and Lightning Tribulations, was incredibly fast.
A rainbow light split off from Taishang Peak and descended, like a divine dragon soaring rapidly through the sky.
It even created many brilliant colors during its flight.
This was the side effect of ascending in rainbow light. Although it was faster than other methods, it was very easy to be detected.
Elder Cheng Fu, confident in his own strength and not fearing detection, and not being someone who needed to hide, therefore chose this method of travel instead of others.
Due to the side effect of ascending in rainbow light,
at this very moment, mortals on the ground, and even ordinary cultivators, could see someone flying in the sky.
Although mortals could sense and see someone flying, they could not recognize him as Elder Cheng Fu, a Half-Immortal, because theoretically, ordinary cultivators who had not broken through the three stages of primordial spirit, physical body, and magic power could also use rainbow light to fly in the sky.
They simply thought it was an ordinary cultivator.
Upon careful sensing, cultivators recognized the immense power of this person and the feeling of having passed tribulations, exclaiming, "It's Elder Cheng Fu!"
Elder Cheng Fu, after all, was a Half-Immortal who had passed two tribulations.
His name was well-known in the surrounding area, and indeed, throughout the cultivation world.
This was someone who was only one step away from potentially becoming a True Immortal!
"What is Old Ancestor Cheng Fu up to?"
In private, cultivators discussed in hushed tones.
However, they did not receive an answer.
During the discussion, someone brought up the possibility of demons appearing again.
At this, the cultivators paused for a moment before unleashing their imaginations.
Suddenly, the discussion became very lively.
"Demons appearing again, that's very possible! Wasn't there a Half-Immortal who attempted tribulation recently?"
"And he failed the tribulation."
"Was it Daoist Taixu? I think that was his title."
"It seems Old Ancestor Cheng Fu intends to eliminate a demon?"
"I feel it's definitely so..."
"This possibility is very high, I think you've already guessed the truth."
Some cultivators, through their discussions, arrived at the truth.
This was not surprising.
In World Seven, the number of Half-Immortals was not large; they were not as numerous as mountains and seas, nor were they as common as stray dogs.
The number of Half-Immortals was limited, not infinite.
Among these Half-Immortals, the only one who had recently attempted tribulation, aiming for the fruit of True Immortality, was Daoist Taixu.
