Breakthrough to Soul Ancestor

Lin Qing chose to break through in Infinity Castle because the demonic aura there was the densest in the entire world. Moreover, as long as one was within Infinity Castle, it could amplify the demonic aura emitted by its demons a hundredfold, even a thousandfold. To Lin Qing, Infinity Castle was a holy land for cultivation.

Lin Qing sat cross-legged and immediately released a towering demonic aura. Under the effects of the Demon King Meditation Method, his aura merged with the demonic aura within Infinity Castle, forming a massive vortex above his head. Like a funnel, the vortex poured that immense demonic energy into Lin Qing's body, driving the growth of his Soul Power.

With a soft pop, Lin Qing's Soul Power bottleneck shattered. His Soul Power trembled, finally reaching level forty.

However, Lin Qing did not stop there. His second Martial Soul emerged on its own, swaying in his hand.

The instant Ah Yin saw Lin Qing's second Martial Soul, she seemed like a subject encountering her sovereign. With a thud, she dropped to her knees. Suppressed by that imperial majesty, Ah Yin prostrated herself before Lin Qing, cold sweat streaming down her face.

Then another incredibly massive wave of demonic aura surged forth, more than ten times greater than the amount used for the breakthrough just now. As the Red Spider Lily swayed, the aura gradually gathered into a ring, changing from blurry to solid.

At that moment, Ah Yin felt her body lighten as the terrifying pressure abruptly vanished, allowing her to raise her head and look at the scene before her.

The ring solidified, turning into a Spirit Ring interwoven with azure and blue light, which gradually settled around Lin Qing's body.

The next moment, three Spirit Rings identical to the newly formed one rose from beneath Lin Qing. The new Spirit Ring slowly descended outside the three rings, taking its rightful place as his fourth Spirit Ring.

Lin Qing slowly opened his eyes and sensed his Soul Power level. "Level forty-one. Not bad."

"Congratulations, Master, on your successful breakthrough." Seeing that Lin Qing had finished breaking through, Ah Yin immediately stepped forward and bowed.

"And thank you for standing guard." Lin Qing said.

"I actually didn't do much." Ah Yin shook her head. "By the way, Master, I saw that your fourth Spirit Ring condensed on its own. Could it be that you are also a Soul Beast Transformation?" Ah Yin appeared somewhat excited.

Lin Qing shook his head. "As my subordinate, shouldn't you be able to sense it clearly? I am not a Soul Beast Transformation. I am a genuine pure-blooded human."

"Then you..." After Lin Qing exposed it, a trace of disappointment flashed across Ah Yin's face, but she soon recovered. What difference did it make whether Lin Qing was a Soul Beast Transformation or not? He was still her master. Whether he was human or a transformed soul beast made no difference.

"This is a special ability of my Martial Soul," Lin Qing said.

Lin Qing extended his left hand and sensed his fourth Spirit Skill. "Not bad."

The name of the Red Spider Lily's fourth Spirit Skill was Demon Blood. It was a passive Spirit Skill, but to Lin Qing, it felt less like a Spirit Skill and more like unlocking an ability he should have possessed from the start.

The effect of this passive Spirit Skill was that Lin Qing could inject his blood into a target's body and transform it into a demon. However, demons transformed this way could at most reach the level of the Twelve Kizuki and could not reach the Demon King level. Unless he became a god and elevated his status once more, demons transformed by his blood could only reach Upper Moon at most.

"Alright, I've already broken through to level forty-one. It's time to add a Spirit Ring to my first Martial Soul."

Lin Qing then clenched his right hand in the air and summoned his Nichirin Blade Martial Soul. Immediately afterward, three Spirit Rings—yellow, purple, and purple—rose up and revolved around him.

When Ah Yin saw Lin Qing's Nichirin Blade Martial Soul, she immediately felt an instinctive disgust originating from her bloodline. Of course, only existences at the Demon King level like Ah Yin, or demons at the Twelve Kizuki level, would feel this way. Ordinary demons would only feel fear upon seeing Lin Qing's Nichirin Blade Martial Soul, not the disgust Ah Yin felt.

Lin Qing withdrew his Nichirin Blade. "By the way, Ah Yin, what level are you now?"

"When I sacrificed myself to Tang Hao, I was level sixty-nine. Now that I've just become a demon, my level has dropped considerably. I'm only at level sixty now," Ah Yin replied.

"Level sixty? Then cultivate in Infinity Castle for now and strive to break through to Soul Sage as soon as possible. Also, within Infinity Castle, you can directly condense Spirit Rings through demonic aura, so you won't need to kill soul beasts to obtain your later Spirit Rings," Lin Qing said.

Hundred-Thousand-Year Soul Beasts that transformed into humans could condense their own Spirit Rings, but this ability could only produce the first six Spirit Rings. After reaching level seventy, a soul beast's essence had basically fully transformed into that of a human, so Spirit Rings from Soul Sage to Titled Douluo still had to be obtained by killing soul beasts.

"Thank you, Master." Ah Yin was deeply moved by Lin Qing's words. After all, she was a Soul Beast Transformation. Unless she had no other choice, she never wanted to obtain Spirit Rings by killing soul beasts.

After that, Lin Qing stopped paying attention to Ah Yin. With a thought, he left Infinity Castle.

Breathing in the fresh air of the forest and feeling nature's presence, Lin Qing's mind became much clearer.

"Let's head to the Star Dou Great Forest first." Having made his decision, Lin Qing began walking toward the Star Dou Great Forest.

Upon arriving at the Star Dou Great Forest, Lin Qing began searching for the soul beast he needed for his fourth Spirit Ring.

With Lin Qing's current physique and spiritual power, he could already absorb a soul beast Spirit Ring that was more than thirty thousand years old.

Lin Qing did not summon Ah Yin to use the Blue Silver Domain to help him search. Instead, he left the choice of his fourth Spirit Ring to fate. Whichever suitable soul beast he encountered would become his Spirit Ring.

The truth was that Lin Qing did not have any particular swordsmanship school he wanted to unlock. Ever since his first Spirit Ring, he had relied entirely on luck. Whatever he encountered was what he got.

However, his luck this time was clearly not very good.

Lin Qing had already entered the mixed zone of the Star Dou Great Forest, an area where Ten-Thousand-Year Soul Beasts gathered.

Yet although Lin Qing encountered several Ten-Thousand-Year Soul Beasts along the way, none met his requirements in age. Most were only slightly over ten thousand years old, while only two or three had reached twenty thousand years.

"Looks like I'll have to go deeper." Unable to find a soul beast of the right age, Lin Qing looked toward the deeper regions of the Star Dou Great Forest, intending to venture farther in.

No sooner thought than done. Lin Qing summoned his Nichirin Blade, focused completely, and cut through thorns and brambles as he made his way toward the middle layer of the Star Dou Great Forest's mixed zone.
