In the library of Spirit City, Ling Feng was leafing through a record about Twin Martial Souls.
He couldn't help asking, "Senior, can we really meet Bibi Dong here?"
The Rakshasa Bibi Dong inside Ling Feng had never told him her real name.
So even though Ling Feng had guessed who she was, he still addressed her as Senior.
"Of course. Do you really not trust me?" Rakshasa Bibi Dong said.
She remembered clearly that in her previous life, she had come here to look up some materials when she met Yu Xiaogang.
Then she had been captivated by Yu Xiaogang's "talent" and set foot on a path of no return.
It wasn't that Ling Feng didn't trust Rakshasa Bibi Dong. He just felt that it was a waste of time. With time like this, he might as well go cultivate!
After all, he had already planned out the path for cultivating his Demon Spider Martial Soul.
He would keep absorbing Soul Rings from Demon Spider Soul Beasts, steadily building up his foundations and evolving his Martial Soul into a Spider King, or even a Spider Emperor.
So the theories here weren't all that important to him.
Just then, Rakshasa Bibi Dong suddenly warned him, "She's here!"
At her words, Ling Feng looked up toward the entrance. A young woman in a Spirit Academy uniform had just walked in.
She looked about seventeen or eighteen, with fair skin and flawless features. Her air was noble and aloof, making her seem difficult to approach.
When Ling Feng looked up at her, she sensed his gaze and glanced over. Their eyes met across the room.
"So beautiful!" Ling Feng couldn't help exclaiming.
That was one of the benefits of a transcendent world: many of the women here truly had flawless features.
Nourished by Soul Power and Martial Souls, their skin didn't have a single blemish.
Some powerful Soul Masters could even live without worldly sustenance, like the heavenly maidens of myth.
Rakshasa Bibi Dong, inside Ling Feng, noticed the momentary daze in his eyes.
She was rather pleased. At last, she had seen Ling Feng lose his composure again.
Young Bibi Dong saw Ling Feng and walked over, meeting his gaze.
"Hm? Why is she coming over on her own?"
Ling Feng had been wondering how to strike up a conversation with Bibi Dong. He hadn't expected her to approach him first.
"You're Ling Feng?" Bibi Dong asked.
Her voice didn't match her noble, aloof bearing. Instead, it was gentle and clear, soothing to the heart.
"You know me?" Ling Feng asked curiously.
Bibi Dong nodded. "I've heard of you. Your Martial Soul is a Demon Spider, and your third Soul Ring is ten thousand years old!"
"Let's get acquainted. I'm Bibi Dong, and my Martial Soul is a Demon Spider too," she said.
Although her Martial Soul was also a Demon Spider, it was the emperor among Demon Spiders: the Death Spider Emperor.
"Hello!" Ling Feng stood and bowed.
Bibi Dong glanced at the book in front of Ling Feng and saw that it was a record about Twin Martial Souls.
"Don't you only have one Martial Soul? Why are you reading this?" Bibi Dong asked.
Ling Feng was reading the book because Bibi Dong in his Sea of Consciousness had told him to. She said it would give him a common topic to discuss with her younger self.
But Ling Feng couldn't explain it that way.
"I'm interested in Martial Soul Theory. I want to read more and strengthen my theoretical foundation."
Bibi Dong nodded, then asked, "So was your third Soul Ring also something you absorbed based on your Martial Soul Theory?"
Ling Feng shook his head. "No. It came from a ten-thousand-year Death Demon Spider. It offered itself to me."
"A Soul Beast offering itself?" Bibi Dong was stunned. She hadn't expected such a thing to really exist.
"Why tell me that? If you said you absorbed it yourself, the Spirit Hall might take you more seriously."
"Because I don't want to lie to you!" Ling Feng said.
"If you try to absorb a ten-thousand-year Soul Ring as your third Soul Ring too, it might get you killed!"
Bibi Dong smiled, thinking that he was an interesting person.
She was already a Soul Ancestor. Why would she absorb a third Soul Ring?
"Oh? You think other people would die if they absorbed a ten-thousand-year Soul Ring as their third?" Bibi Dong asked.
Seeing the two chatting so happily, Rakshasa Bibi Dong, in Ling Feng's mind, breathed a sigh of relief.
She had been worried that Ling Feng wouldn't earn the trust of her younger self and wouldn't be able to persuade her to go out and gain experience.
Tonight, I'll tell Ling Feng the secret to cultivating Twin Martial Souls. He can use it to earn the trust of my other self! Rakshasa Dong thought.
Just then, she heard Ling Feng say, "Of course they'd die. A Soul Grandmaster at level thirty doesn't have the physical strength to withstand the Soul Power impact of a ten-thousand-year Soul Ring, and their spirit can't withstand the Soul Shock either."
"Just like the Twin Martial Soul cultivator mentioned in this record. His body wasn't strong enough to bear the strain of too many Soul Rings, so he exploded and died!"
"How is that possible? He knows the secret to cultivating Twin Martial Souls? I haven't even told him yet!" Rakshasa Bibi Dong was shocked.
The true secret could be summed up in a single sentence, while false teachings filled ten thousand books: the key was the strength of the body and spirit.
Rakshasa Bibi Dong had never expected Ling Feng to work out how to cultivate Twin Martial Souls just from reading a single record.
When young Bibi Dong heard Ling Feng bring up Twin Martial Souls, her eyes lit up. She pressed him for more. "Are you saying that if a Twin Martial Soul cultivator has a strong enough body and soul, they won't run into problems while cultivating?"
"Exactly!" Ling Feng nodded.
This question had troubled Bibi Dong for a long time. Now that she had heard Ling Feng's answer, the weight on her heart finally lifted.
"Then how can you prove you're right?" Bibi Dong asked.
Ling Feng thought for a moment, then said confidently, "I can use myself as an experiment!"
"Although my third Soul Ring is ten thousand years old, it was offered to me by a Soul Beast."
"According to the records in the Spirit Hall library, the recorded limit for a fourth Soul Ring is five thousand years."
"I plan to absorb another ten-thousand-year Soul Ring as my fourth and use that to test my theory."
"I'll keep strengthening my body and mental power so I can withstand the impact of a ten-thousand-year Soul Ring."
"If I succeed, that will prove that the number of years a Soul Master's Soul Ring can have depends on the strength of their body and spirit."
When Bibi Dong had first heard that Ling Feng's third Soul Ring came from a Soul Beast offering itself, she hadn't paid him much attention.
But when she heard that he planned to absorb a ten-thousand-year Soul Ring as his fourth, his courage stunned her, and she couldn't help admiring him.
"You... you're really going to do that? What if you fail?"
Bibi Dong was worried. She didn't want such an interesting person to die just like that.
Ling Feng shook his head. "I won't fail!"
Bibi Dong sighed. From Ling Feng's expression, she could tell there was no talking him out of it.
"Then do you know how to strengthen your body?" Bibi Dong asked.
"Mm! I know a few methods," Ling Feng said.
Bibi Dong grew curious and couldn't help asking, "Really?"
Ling Feng smiled. "Actually, my body might already be stronger than yours."
"If you don't believe me, we can seal our Soul Power and have a match!"
