Xiao Fei, through the cultivation of the "Ding Shen Jue," spent three years and finally condensed a Ding Shen rune.
To test the rune's performance and power, the Flying Fish had to make some sacrifices.
After several rounds of testing, he discovered that this rune was effective regardless of which part of the Flying Fish's body it was attached to.
Each application could immobilize the Flying Fish for at least the duration of an incense stick.
During this time, the Flying Fish was completely unaware, allowing Xiao Fei to do as he pleased, even if he broke a few of its bones, the Flying Fish would not wake up.
If it were an enemy, once immobilized by his Ding Shen rune, it would be as good as dead.
However, during its use, the power of the Ding Shen rune would gradually decrease.
For instance, when he used the Ding Shen rune to immobilize the Flying Fish, as the Flying Fish struggled and resisted, the rune's power would gradually be worn away.
Until after the duration of an incense stick, his Ding Shen rune would become dim and lusterless, losing its suppressive effect on the Flying Fish.
If the Flying Fish was not yet dead, it could break free from the rune's seal and regain its mobility.
At this point, he could only retrieve the rune into his sea of consciousness and nourish it with his divine sense, which would take about ten days to fully recover.
With this rune in hand, he now possessed the strength to instantly kill cultivators of the same Golden Core stage.
Moreover, this rune had only just taken shape, and as he nurtured it for longer, its power would gradually increase.
If he continued to nurture it without using it, its ultimate power would be limitless.
Having only tested it on the Flying Fish, Xiao Fei was not entirely satisfied.
Finally, when Huang Feifei returned from the Treasure Pavilion, Xiao Fei eagerly pulled her into his cave dwelling and closed the door.
"Feifei, could you help me test a divine ability? You might lose consciousness and the ability to resist during this period."
If anyone else had made such an inappropriate request, Huang Feifei would have drawn her sword and fought them to the death.
But facing Xiao Fei, she merely blushed slightly.
"I just came back from outside, covered in dust and sweat. Should I go bathe and change before coming?"
"No need, I'll be done quickly!"
Xiao Fei seemed a bit impatient.
"Alright!"
Huang Feifei cooperatively followed Xiao Fei into a secret chamber.
At this moment, Xiao Fei once again summoned his Ding Shen rune and directly imprinted it on Huang Feifei's forehead.
Huang Feifei, a formidable Nascent Soul expert, lost consciousness just like that, standing there like a block of wood.
Xiao Fei walked up to Huang Feifei, tapping her here, poking her there, his index and middle fingers bent, flicking her on the head several times.
He even used a sharp small sword to scrape off several fine hairs from Huang Feifei's face.
From beginning to end, Huang Feifei showed no reaction.
It was only after about ten breaths that Huang Feifei regained consciousness. Upon checking herself, she seemed to find nothing unusual.
"Young Master! Are we done?"
"Mm! Done. You can go back and rest. I'll find you again in a few days."
After sending Huang Feifei away, Xiao Fei took out his Ding Shen rune again to examine it.
He found that the rune had become dim and lusterless, on the verge of collapse, consuming much faster than when sealing the Flying Fish. It would require at least ten more days of nurturing before it could be used again.
He was quite satisfied with the results of its initial use.
Huang Feifei was an early-stage Nascent Soul expert. With ten breaths, he should have been able to dismember her into several pieces.
However, due to her rapid advancement, Huang Feifei was still relatively weak among early-stage Nascent Soul cultivators, and it would take some years of tempering to catch up.
If dealing with other Nascent Soul experts, the effect might be somewhat reduced.
In the following period, Xiao Fei tested it on Huang Feifei a few more times to confirm the efficacy of the Ding Shen rune against Nascent Soul experts, and the results were quite satisfactory.
While Xiao Fei was in seclusion cultivating, the Black Flood Dragon clan and the White Ape clan of the East Sea engaged in a fierce battle, with both sides suffering casualties.
Although the White Ape clan was not as strong as the Black Flood Dragons, their ability to survive in the East Sea naturally meant they had their own means of self-preservation.
The White Ape clan's backer was the Mountain-Moving Stone Monkey clan, whose strength in the East Sea was no less than that of the Black Flood Dragon clan.
After the Mountain-Moving Stone Monkeys intervened, both sides quickly reached a settlement.
As long as they could talk things through properly, they would soon discover the anomalies within the matter.
After investigation by both sides, it was discovered that someone had impersonated their White Ape clan and committed many misdeeds.
This was outrageous, daring to trick these great clans of the East Sea.
For a time, the entire East Sea was stirred up, vowing to find the person who had impersonated the White Apes.
