He understood that this time, he had benefited from the theory beyond limits, perhaps along with Qian Daoliu pulling strings behind the scenes, allowing him to successfully obtain a Soul Bone.
Li Fei merely gave the Soul Bones in the outer section a cursory glance. Most of them were under thirty thousand years old, and they were all arm bones or leg bones—not his target. He continued deeper inside. As he went farther in, there were several precious torso bones and skull bones, while the innermost area even contained three Hundred Thousand Year Soul Bones.
Reluctantly shifting his gaze away from the three Hundred Thousand Year Soul Bones, Li Fei saw that they were all leg bones and arm bones, none of which suited him. He slowly walked toward a skull bone emitting a faint blue glow. Written beneath its display case were the words: Spirit Condensing Wisdom Skull.
He placed his token on the cover, and the formation inscribed upon it instantly vanished, revealing the skull bone within.
Only after taking it into his hands did Li Fei finally let out a breath of relief. He then left the treasury and showed the skull bone in his hand to the elder guarding the pavilion.
"Good eye! This Soul Bone can be considered one of the true treasures in this treasury!" the elder said in surprise.
"Just luck. Then, Elder, I'll take my leave first!"
Li Fei smiled and gave the elder a slight bow before heading behind the Worship Hall. With his current cultivation, refining a Soul Bone would take a long time. It would be safer at Qian Daoliu's residence.
Over the past few years, he had met Qian Daoliu a few times. Usually, he had accompanied Qian Renxue while she studied martial souls and cultivation. Because of Qian Renxue, the two could be considered acquainted, so refining it there would be best.
"Greetings, High Priest! This junior wishes to refine a Soul Bone here. Would that be permissible?!"
Upon entering the villa, Li Fei saw Qian Daoliu drinking tea. At a table in the distance, Qian Renxue was studying knowledge related to royal affairs. He immediately stepped forward and bowed.
"Mhm." Qian Daoliu nodded, indicating that he understood.
Seeing Qian Daoliu agree, Li Fei smiled at Qian Renxue, then walked to an open space. Taking out the Wisdom Skull, he began refining it.
As the Wisdom Skull neared Li Fei's forehead, it directly transformed into a phantom and entered him. Li Fei felt as though he had been enveloped by a cool ocean, his soul seeming to leave his body. All he could feel was that coolness; he could sense nothing else.
Blue fluorescent light circled above Li Fei's head, continuously scattering specks of light that merged into his body.
"Grandpa, when do you think Li Fei will wake up?!"
Watching Li Fei remain seated with his eyes tightly shut even after most of the day had passed, Qian Renxue asked in confusion.
"Xue Er, have you forgotten? It took you five days to refine the Cloud Illusion Soul Bone. This Wisdom Skull is slightly inferior in quality to the Cloud Illusion Skull. With Li Fei's spiritual power, it will take at least three days!" Qian Daoliu said with a smile.
"Oh!" Qian Renxue nodded and continued reading her book on the royal family.
As the skull bone was refined bit by bit, Li Fei could sense more than a hundred silver points of light appearing in his sea of consciousness, like stars scattered across the sky. Their number was still increasing.
He could also feel the benefits of this Soul Bone. His thoughts could accelerate, and he began actively condensing his spiritual power into silver points of light.
As the points of light increased, they gathered together. Like an illusory river, they began surging and flowing through his mind.
Hmm, his spiritual power has actually reached the level of a Soul Douluo. Perhaps he truly will become Xue Er's right-hand man in the future. Qian Daoliu thought in surprise. In just three days, a single Soul Bone had raised his spiritual power to the Soul Douluo level. He had never even heard of such a thing before.
Even as the inheritor of the Angel's Eight Trials, he had only possessed Soul Douluo-level spiritual power when he was a six-ringed Soul Emperor. The reservations he had once held toward Li Fei also vanished.
As Li Fei felt his soul return to his body, he sensed that the entire world had become different. Everything was distinctly layered, and he could clearly see its essence. At the same time, he understood the skill the Soul Bone had granted him—Insight.
"This is the Wisdom Skull's original skill. It allows me to clearly perceive everything and even comes with spiritual attacks. Not bad! Not bad!"
Insight was an extremely practical skill and came with spiritual attacks. Together with his third soul skill, Perception, his methods in the spiritual aspect were now nearly complete. Li Fei was very satisfied with this.
Opening his eyes, Li Fei found that Qian Renxue was gone. Only Qian Daoliu remained, sitting on the sofa and drinking tea as he watched him with a smile.
"Thank you, High Priest!" Li Fei rose and said respectfully.
"You are very good! You are qualified to remain by Xue Er's side!" Qian Daoliu looked at Li Fei with a stern yet satisfied expression. "I heard from Xue Er that you will also be going to the Heaven Dou Empire this time?!"
"Yes, High Priest. Her Highness and I have made an agreement. Once we reach the Heaven Dou Empire, I will assist her with her undercover mission!"
"It seems she truly trusts you, to have even told you about the undercover mission. Even Sister Ying, who has always taken care of her at her side, does not know." Qian Daoliu looked Li Fei over in surprise before continuing, "Xue Er will not have many people with her when she goes to the Heaven Dou Empire this time. I hope you can protect her well!"
"This junior will certainly give it his all!" Li Fei said solemnly.
"Enough! Xue Er is preparing things for the undercover operation. You should return and make your own preparations as well. Gather at the gates of Spirit City tomorrow morning at eight!" Qian Daoliu handed Li Fei an envelope and waved him away.
"Yes!"
The next day!
Li Fei arrived at the gates early and waited. He had already spoken with his parents and Xiao Fan. During the time he was in the Heaven Dou Empire, he could not contact his family. Even if the two of them saw him in Heaven Dou City, they were not to greet him immediately.
Inside the envelope, he found the new identity Qian Daoliu had prepared for him: the son of a fallen noble from a border region, along with a letter of introduction for entering Heaven Dou Royal Academy.
There was no need to think about it. He would be going undercover as well, using his new identity to help Qian Renxue gain control of the Heaven Dou Empire. All information about his time in Spirit City would also be completely erased.
Before long, Qian Daoliu arrived with Qian Renxue. Sister Ying followed behind them, leading three Black Scale Horses. These would be the means of transport for him and Qian Renxue.
"Go, Xue Er!" Qian Daoliu turned and handed the reins of a Black Scale Horse to Qian Renxue without saying much else.
"I'm leaving, Grandpa! Take care of yourself!"
Qian Renxue took the reins and mounted the horse, looking at Qian Daoliu with reluctance.
Li Fei and Sister Ying also mounted their horses. After Qian Renxue finished saying goodbye, the three headed toward Heaven Dou City. Not long after they left, two streaks of light flew out from Spirit City and followed them.
After several days of travel, the three finally arrived in Heaven Dou City.
"Xue Er, Sister Ying, we'll part ways here!"
On a street near the imperial palace and Heaven Dou Academy, Li Fei said in a low voice.
"You must be careful too. Unless it is absolutely necessary, do not reveal your Spirit Ring configuration!" Qian Renxue reminded him.
"Mhm." Li Fei nodded.
Sister Ying moved to Qian Renxue's side, and the two instantly vanished without even the slightest fluctuation.
