"It's incredible... Yi'er has actually mastered the Power of Illusion Origin? When did he master it??"
Yu Xin exclaimed repeatedly, formerly composed, but the scene before him made it impossible for him to remain calm.
Those around him, including Yu Xianyun, also appeared perplexed, unaware of when Lu Yi had mastered the Power of Illusion Origin.
However, their emotions soon relaxed.
Yu Xianyun breathed a sigh of relief and said somewhat thankfully, "Thank goodness Yi'er has mastered the Power of Illusion Origin, otherwise the consequences would have been unimaginable!"
The others nodded in agreement.
If not for Lu Yi's Power of Illusion Origin suppressing the unformed Origin Power of the Yu Family Ancestor, just the Heart Demon of the Immortal Venerable Realm that appeared would have caused massive losses to the Yu Family!
"Yes, we owe a lot to Yi'er."
"But it's really strange, what happened to our ancestor? Given our lineage, Heart Demons should rarely occur, let alone in our ancestor."
The Power of Illusion Origin focuses on Divine Sense, and cultivators with strong Divine Sense are generally less prone to Heart Demons. If Heart Demons do appear, the trouble becomes greater. Among the Yu Family Practitioners who have reached the Golden Immortal Realm or higher, those who experience Heart Demons are few and far between, not to mention the Immortal Venerable of the Yu Family Ancestor.
With the profound accumulation of the Yu Family Ancestor, such a situation should not have occurred.
"Not sure... I hope the ancestor recovers."
The faces of the Yu Family's higher-ups clearly showed their concern.
At that moment, by Yu Cheng's side, after Lu Yi suppressed the manifested Heart Demon, he turned to Yu Cheng.
Yu Cheng's body trembled slightly, his brow furrowed, his aged face slightly pale, indicating that his condition was not good.
Lu Yi frowned, not entirely sure why Yu Cheng had encountered a Heart Demon, but he knew the situation was not optimistic.
However, Lu Yi was not entirely out of options.
A strand of incredibly Mysterious Tao Light flashed in his eyes, and Taoist Energy flowed around his body, so visibly strong it could be seen with the naked eye!
After breaking into the Immortal Monarch Realm, with laws inscribed in his Inner World, Lu Yi's manipulation of Taoist Energy had become even more adept.
At this moment, Lu Yi was using an Immortal Technique called "Taixuan Heart Clearing Mantra," specifically aimed at countering Heart Demons.
This Immortal Technique was something Lu Yi found in the Yu Family's Book Storage Pavilion. Although Lu Yi himself, with a solid foundation, had never faced a Heart Demon and might not face one in the future, his senior sisters were also in cultivation and could potentially encounter Heart Demons.
So, Lu Yi cultivated the Taixuan Heart Clearing Mantra, adopting a better safe than sorry approach.
Unexpectedly, while he and Liu Ningshuang had not used it, it was the Yu Family Ancestor, skilled in Divine Sense, who first needed it.
Lu Yi felt somewhat mixed at this moment.
Considering that the Yu Family Ancestor was a powerful being at the Immortal Venerable Realm, to ensure the success rate, Lu Yi did not hold back, directly invoking the Taoist Energy, even integrating the Power of Illusion Origin.
His goal was not merely to save the Yu Family Ancestor—if he only saved the Yu Family Ancestor, then this enlightenment might fail, and it could also affect his own Cultivation Base.
This was something Lu Yi could not accept.
His aim was to break the Heart Demon and also help the Yu Family Ancestor truly comprehend the Power of Illusion Origin.
He formed seals with his hands, and the next moment, Mysterious vibrations spread out in all directions.
This vibration carried a strange and profound aura, as if it could completely soothe and calm a person.
The vibration enveloped the Yu Family Ancestor. Immediately, the Yu Family Ancestor's body shuddered, and his previously furrowed brow gradually relaxed, his complexion also regaining its color from its previously pale state.
Lu Yi raised his eyebrows, for he himself did not have a Heart Demon, and since learning the Taixuan Heart Clearing Mantra, he had never used it and was unsure of its effects.
Unexpectedly, the results were quite remarkable.
Of course, this was also thanks to his leveraging Taoist Energy and integrating Origin Power.
Seeing the immediate effect and the gradually normalizing complexion of the Yu Family Ancestor, Lu Yi also felt reassured.
Indeed, it wasn't long before the illusory world, nearly dissolving into a specter, that surrounded the Yu Family Ancestor once again solidified, now radiating Mysterious Tao Patterns, drawing closer and closer to the true Origin Power.
Lu Yi stood within the illusory world yet seemed separate from it.
At this level of illusory world, there was no impact on Lu Yi. He worried that if he now stopped the Taixuan Heart Clearing Mantra, the Heart Demon might again afflict the Yu Family Ancestor.
After all, this Heart Demon had appeared too suddenly and was somewhat unusual.
As time passed, gradually, the illusory world around the Yu Family Ancestor seemed to transform into a real world, powerful and Mysterious waves spreading out exerting considerable pressure on Lu Yi.
He raised his eyebrows and disappeared from the spot, leaving the illusory world surrounding the Yu Family Ancestor.
He could clearly sense that the Yu Family Ancestor had now mastered the Power of Illusion Origin—the task was completed.
Lu Yi appeared next to Yu Xin and others. Seeing Lu Yi, the previously tense faces of Yu Xin and the others immediately asked, "Yi'er, how is it?"
Lu Yi smiled and said, "It should be fine now."
As Lu Yi finished speaking, Yu Cheng opened his eyes.
His eyes still held a trace of lingering fear, his expression quite apprehensive.
