Within the black and white barrier, Li Xuan had been fighting continuously for ten full days.
For ten days, Li Xuan had barely stopped his attacks. Because every time he slew a wraith, more would crawl out from underground to join the horde. Even with Li Xuan’s incredibly robust physique, he was beginning to feel drained.
Although Li Xuan could slay a large area of wraiths with each strike, the sheer number of them was overwhelming. Moreover, these wraiths could be killed and revived, and their fearless charges were relentless. Li Xuan, after all, was a living being.
There was a reason why they said a swarm of ants could kill an elephant.
*Buzz.*
At this very moment, a buzzing sound arose, and the next instant, the Heavenly Dao Brush appeared directly before Li Xuan.
"Damn it, Young Master, you're playing with your life," the Heavenly Dao Brush exclaimed in surprise, looking at Li Xuan's slightly pale face.
"How did you get in here?" Li Xuan asked, slashing an approaching wraith as he spoke, then turning to face the Heavenly Dao Brush.
Hearing this, the Heavenly Dao Brush remembered its purpose for entering and hurriedly said, "Young Master, if you can't hold on any longer, you can leave this place using the activation key. The Good and Evil Sword said that by placing the two keys together, you can leave."
Li Xuan nodded slightly, then moved his figure and unleashed another sword strike.
The next moment, Li Xuan directly took out the black and white chess pieces and stacked them together. Immediately, a black and white light enveloped him, instantly teleporting him out.
"Damn it, Young Master, you're running away already?" The Heavenly Dao Brush was stunned by this, looking at the densely packed wraith army closing in. The Heavenly Dao Brush quickly dripped a drop of ink from its tip, and a black light surged forth before disappearing.
"Young Master, you're too dishonorable!" As soon as it emerged, the Heavenly Dao Brush angrily approached Li Xuan, who was meditating and recovering.
Li Xuan opened his eyes upon hearing this, clear confusion in his gaze.
"Young Master, you only cared about saving yourself!" the Heavenly Dao Brush said with great grievance.
Li Xuan blinked in surprise and replied, "Didn't you enter without the activation key? Besides, you're just a brush, and the wraiths won't attack you."
The Heavenly Dao Brush froze on the spot. What the Young Master said… seemed to have some truth to it?
Seeing that the Heavenly Dao Brush had fallen silent, Li Xuan smiled and closed his eyes again to recuperate. After all, ten days of combat had indeed taken a significant toll on him.
A full hour passed before Li Xuan slowly opened his eyes again. As he exhaled a breath of stale air, Li Xuan's condition returned to its peak.
To Li Xuan's surprise, this battle had actually further solidified his cultivation. Moreover, he faintly felt his realm beginning to loosen, bringing him one step closer to the advanced stage of the Dao Ruling realm.
"Master." As Li Xuan's thoughts stirred, the Good and Evil Sword instantly appeared before him.
Li Xuan nodded slightly and asked, "Who set up the black and white barrier within you?"
The Good and Evil Sword replied, "A peerless expert. However, my memories of him are already fading."
Li Xuan frowned slightly but quickly relaxed. Some powerful individuals indeed possessed such means to make one forget their appearance or that specific memory. For the Good and Evil Sword to be affected like this, that person must have been incredibly powerful.
"Master, actually, my previous inheritors also entered my body. But none of them obtained the activation key, so you are the first person to enter the black and white barrier," the Good and Evil Sword said.
Li Xuan was taken aback. So he was the first test subject?
"It's quite good in there, very suitable for me," Li Xuan said with a smile. Such a place that allowed for rapid combat and self-improvement was indeed increasing the Good and Evil Sword's value.
"Master, do not be careless. There are not just wraiths inside. After so many years, a Wraith King might have been born. The strength of a Wraith King is extreme, and it's possible it has already developed sentience," the Good and Evil Sword warned.
Li Xuan was taken aback. The being who set up this black and white barrier was truly heaven-defyingly powerful. But this also meant it was a treasure trove for Li Xuan. At the very least, pressure fostered motivation.
"I need to go out and take care of some matters. I'll continue after that," Li Xuan said with a smile, his figure disappearing from the spot.
"Broken Tower, have you noticed a problem?" After Li Xuan's departure, the Heavenly Dao Brush suddenly spoke.
The Azure Spirit Pagoda looked at the Heavenly Dao Brush with confusion, clearly not understanding what it meant.
Seeing this, the Heavenly Dao Brush sighed with the air of someone dealing with an incorrigible student, "Broken Tower, even the Good and Evil Sword has improved because of Young Master and is very suited to his cultivation. What about you? Besides generating spiritual energy, what else can you do?"
The Azure Spirit Pagoda: "..."
The Heavenly Dao Brush continued, "As for me, my abilities are also gradually weakening. If this continues, you and I might be slowly forgotten by Young Master."
The Azure Spirit Pagoda replied, "No way, we've followed Master for so many years. And over the years, I haven't been stingy with providing spiritual energy to nourish this Town Prison."
The Heavenly Dao Brush said grumpily, "Can't Young Master just find a few spirit veins? Also, although we have been with Young Master the longest, our usefulness is decreasing. Can't you feel the crisis?"
The Azure Spirit Pagoda fell silent. What the Heavenly Dao Brush said was not without reason. Although Li Xuan wouldn't abandon them, as his strength increased, their utility to him indeed diminished.
"Then what should we do?" the Azure Spirit Pagoda asked the Heavenly Dao Brush.
The Heavenly Dao Brush pondered for a moment and then said, "Transformation, evolution!"
"How do we transform and evolve?" the Azure Spirit Pagoda asked, confused.
The Heavenly Dao Brush glanced at the Good and Evil Sword floating in mid-air and slowly said, "Wait. A powerful expert will appear soon."
The Azure Spirit Pagoda fell into a speechless silence. After a moment, it suddenly asked, "Broken Brush, how did you get inside him before?"
The Heavenly Dao Brush chuckled smugly, "Do you really think I'm just an ordinary brush? Broken Tower, Broken Tower, you're too naive."
The Azure Spirit Pagoda looked at the Heavenly Dao Brush with a hint of exasperation, saying, "The way you are now, you're really asking to be beaten."
The Heavenly Dao Brush laughed and said, "Broken Tower, work hard. If we are truly forgotten by Young Master, then we can truly exit the stage. Look at Azure Dragon, how long has it been since it appeared?"
"That's true," the Azure Spirit Pagoda thought for a moment and then nodded.
Azure Dragon: "..."
