Based on Lin Yu's speculation, ordinary cultivators would not do such a thing; only someone with a deep hatred for the ancient Phoenix Clan would resort to such a vicious act.
The perpetrators were likely not from the ancient Dragon Clan, the ancient Xuanwu Clan, the ancient White Tiger Clan, or the ancient Qilin Clan, all of which were supreme clans.
Both being supreme races, if they were to "ruthlessly kill" the supreme phoenix clan in this way, it would be no different from a complete falling out.
From the very beginning of the fantasy world, although the demon beasts of this supreme race had some conflicts with each other, they essentially supported the Demon Race together. Lin Yu really couldn't figure out why they wanted to target the ancient phoenix clan.
In a world where ordinary cultivators wouldn't do such a thing, there's neither the condition to cast a seal nor the need to.
"An ordinary cultivator wouldn't possess something like this Heaven-Mending Fragment!" Lin Yu thought to himself. "The power within Feng Nianzhi most likely originates from the Heaven-Mending Fragment. To complete the seal using power comparable to the Heaven-Mending Fragment, she must be far more than just an ordinary being."
According to the Hongmeng System's deductions, when Lin Yu first tried to merge the two forces, the two forces were about 90% similar.
"Ninety percent? What else could it be but a fragment of the Heaven-Mending Stone?" Lin Yu frowned.
"Fellow Daoist, I really have no idea. Please go back and thank me first, and allow me some time to think about it carefully," the black-robed high priest said politely.
Seeing that there was no progress with the black-robed high priest and Feng Nianzhi, Lin Yu could only nod and return to his room.
Perhaps it was the change in his surroundings that broadened his perspective, but Lin Yu suddenly had a new idea.
"Could it be that the person behind this seal isn't actually that strong?!"
When this thought suddenly popped into Lin Yu's mind, he was almost startled!
After all, since the other party was able to use the Heaven-Mending Fragment, Lin Yu had previously assumed that he was a hero of the modern era.
Lin Yu knew that not everyone had his ability to easily control the fragments of the Heaven-Mending Stone.
In this era of Dao Qi, there are probably only a handful of cultivators who can wield the power of the Heaven-Mending Fragments. Therefore, when he was thinking, Lin Yu focused his thoughts on a few cultivators with relatively strong power.
However, just now, Lin Yu suddenly remembered that the black-robed high priest could also use the fragments of the Heaven-Mending Rift to create a land of yellow sand, right?
This starting point illustrates that the fragments used to mend the heavens during the Dao Qi era are fundamentally different from those used during the Three Thousand Immortal Realms era!
Even without fully mastering the power of the fragments used to mend the heavens during the Dao Qi era, one can still manipulate them to do certain things!
This was a point that Lin Yu had previously either intentionally or unintentionally overlooked.
After realizing this, Lin Yu suddenly felt a sense of enlightenment.
After waiting for about half a day, night fell.
Later that evening, Lin Yu calculated that Feng Nianzhi's body had almost fully recovered, so he went to find her again.
Just as Lin Yu had predicted, the rosy cheeks on that little face had returned, and the paleness had completely disappeared.
"Feng Nianzhi, regarding the seal, I'd like to try sensing it again." Lin Yu crouched down, gazing at the short Phoenix Lord.
Upon hearing this, Feng Nianzhi simply nodded, showing no particular resistance to the arrival of Lin Yu's power. It was as if she had anticipated Lin Yu's arrival, and she had no objection to his coming or his decision.
Lin Yu once again used his spiritual power to enter the seal inside Feng Nianzhi's body. After touching the power within Feng Nianzhi's body, Lin Yu could clearly feel that Feng Nianzhi's body tensed up.
The same thing happened when I touched Feng Nianzhi's body before. So many years have passed, and this seal has become related to Feng Nianzhi's life and death to a certain extent. The longer it drags on, the greater the danger.
"If we can break this seal as soon as possible, everything will be fine," Lin Yu thought to himself.
But the real fear is that if Feng Nianzhi's seal cannot be broken in ten lifetimes, she will probably have to live like this forever.
Especially for the ancient phoenix clan, "life" is a very long time. For the ancient phoenix clan, which can be reborn from the ashes, their lifespan can almost reach the point of immortality.
Even if Feng Nianzhi could survive for tens of thousands of years in this form, it would mean enduring the torment of the seal for tens of thousands of years.
As the person directly involved, Feng Nianzhi knew this better than anyone else.
The high priest in black robes was also busy, appearing as usual, but this time, his gaze towards Feng Nianzhi held a hint of worry.
"I'll trouble you with this matter, fellow Daoist." As the black-robed high priest said this, his gaze towards Lin Yu held a hint of pleading and expectation.
Upon reflection, it's been so long since Feng Nianzhi was sealed, and they haven't found any way to break through the seal. However, Lin Yu's appearance has clearly brought a new possibility to the matter of breaking the seal.
Whether it's Feng Nianzhi or the Black-Robed High Priest, whether it's from Feng Nianzhi's personal perspective or from the perspective of the entire ancient Phoenix clan, breaking through this seal is an extremely important matter.
The black-robed high priest was well aware that he had persevered for many years, and the main reason he had been able to do so was that there was no one in the ancient Phoenix clan he could entrust with his duties.
Feng Nianzhi is still young and is also under a seal. The black-robed high priest is really worried about her being affected by this!
"You previously said that the power sealed within the Phoenix Lord's body is somewhat similar to the fragments of the Heaven-Mending Fragment, and that they can merge with each other? Doesn't this mean that the two powers originate from the same place?"
"If we use the power of fusion—that is, the power of the Heaven-Mending Fragment in your possession—to bring out the seal within the Phoenix Lord's body, wouldn't we be able to completely dismantle the seal's power?"
The high priest in black robes shared his thoughts.
In his view, as long as the seal could be removed from Feng Nianzhi's body, even if the seal could not be completely broken, it would be enough to ensure that Feng Nianzhi was not affected.
The idea is simple: essentially, it's not about breaking the seal, but about finding a way to remove it.
The fusion of the two forces can, to some extent, alleviate the power sealed within Feng Nianzhi's body. The black-robed high priest's words were clearly the result of considerable deliberation.
