Qin Feng and the others could understand Meng Ying's resentment towards the Hehuan Sect.

Tang Yan of the Hehuan Sect had brutally murdered Mengying's sister, and this hatred would not be easily resolved even if the other party died. It had become a knot in her heart.

However, Qin Feng had not anticipated that the situation in Yizhou would become so complicated.

Qin Feng asked Meng Ying, "What are your plans now? Do you want to come with us?"

Mengying shook her head. "Thank you, but I need to go and rejoin my sect. This matter isn't over yet."

Qin Feng nodded, not trying to stop her. He expressed regret over Meng Ying's experience, but since they were only casual acquaintances, he didn't say much more.

Qin Feng and his group planned to continue their journey towards the Heavenly Sword Sect.

At this moment, Mengying called out to Qin Feng, who was about to leave, and handed him a jade slip.

Qin Feng didn't take it immediately, looking puzzled. "What's this?"

Mengying explained:

"I noticed you were quite interested in my music. Here are some insights into the principles of music and some basic analysis of the soul. I hope they will be helpful to you."

Qin Feng was overjoyed. He really needed this kind of knowledge. He could forget about music and the like, but he was lacking in knowledge about the soul.

Among the cultivation techniques and secret arts he had previously acquired, very few concerned the soul.

He hesitated for a moment, "Wouldn't this break the rules of your sect?"

Mengying was even more grateful upon hearing this. She shook her head and said, "These are my own insights and some of the things I've learned by chance. They have nothing to do with Miaoyinfang. Don't worry."

Qin Feng didn't stand on ceremony, accepted the gift, and thanked him.

After Mengying left, he couldn't wait to use his divine sense to decipher it.

Upon reading this, he immediately beamed with joy. It was truly a case of good deeds being rewarded; the jade slip's explanation of the soul was remarkably clear and concise.

Soul power, like spiritual power, has cultivation levels; it is another form of energy.

When one's divine soul is powerful enough, it can even become immortal and exist eternally, but this is only in theory, and no one has ever achieved it.

The jade slip also contained two soul-soul secret techniques. One was called the Soul-Startling Thrust, specifically designed for attacks on the soul; the other was called Soul Armor, used for soul defense.

Both of these secret techniques are what Qin Feng needs.

Seeing the joy on Qin Feng's face, Leng Yuexi asked curiously, "Could this thing be useful to you?"

Yin Tiantian also asked in confusion, "That's not right. She's only in the mid-stage of the Golden Core realm, while you, Junior Brother, are already at the King realm. Could it be that you can still use Mengying's things?"

Qin Feng nodded with absolute certainty.

"Yes, very useful. Not only useful to me, but also very useful to you."

You can use music to cultivate your temperament and calm your mind; if you are interested, you can study it.

More importantly, this jade slip explains the Dao of the Divine Soul very clearly and concisely, and also includes two secret techniques for cultivating the Divine Soul, which are very practical and extremely rare.

Yin Tiantian was a little suspicious, "Really? Junior Brother, you're practically exaggerating its value."

Qin Feng said seriously, "Of course it's true. The soul can be said to be the foundation of a person. Without spiritual power, the body is still yours, but without the soul, you are no longer yourself."

Do you remember the trip to the Palace of Bliss? Those people were all controlled; it was all because of something wrong with their souls.

The jade slip that Miss Mengying gave us contains a defensive technique and an offensive technique, both targeting the soul, making them extremely valuable.

"I've seen so many cultivation techniques and secret methods, but those related to the spirit and soul are extremely rare."

Seeing Qin Feng's serious expression, Yin Tiantian also became serious, "If that's really the case, then she just handed over something so important to us like that?"

Qin Feng sighed with emotion:

"I don't know what she was thinking. Maybe she was grateful to us for saving her life, and also thanked us for indirectly avenging her sister."

She was only thinking about repaying us; as for the value of this jade slip, she probably didn't even realize it herself.

Yin Tiantian nodded, "Then we've been rewarded for our good deeds, so this is a good deal."

Qin Feng chuckled, "It's not just a loss, it's a huge profit. Next time I see her, I'll help her out if I can."

Yin Tiantian, Xiao Fan, and Leng Yuexi all nodded.

Qin Feng made a copy of the jade slip for them and began to study it himself.

Neither of the two secret techniques was particularly complicated. After pondering them for a while, he gained a basic understanding and was able to master them. He then called Leng Yuexi to try them out.

"Yuexi, let's give it a try. You attack and I'll defend."

Leng Yuexi nodded, and an attack invisible to the naked eye came toward Qin Feng's forehead.

Qin Feng sensed it with his divine sense; Leng Yuexi's attack was a small sword formed from condensed soul power.

He tried to resist with his spiritual power, but found it useless. The small sword pierced through his forehead and entered his dantian, launching an attack on his soul.

At this moment, Qin Feng's soul was clad in armor, protecting him.

Leng Yuexi's soul power sword was silent and strange, only revealing its power when it entered Qin Feng's Purple Mansion.

The small sword pierced the soul armor with a piercing clang before shattering.

Even with the protection of his soul armor, Qin Feng could still feel the power of the stab coming at him.

Without this layer of protection, even with his current powerful soul, he wouldn't be seriously injured, but he would still be temporarily frozen. This soul technique is quite rare.

After Leng Yuexi's soul power sword dissipated, her head slumped, and she felt a moment of mental confusion.

Qin Feng noticed her unusual behavior and immediately asked with concern, "Xiao Xi, are you alright?"

Leng Yuexi quickly regained her senses and shook her head. "I'm fine, but this soul technique should be used with caution, or it could backfire."

Qin Feng nodded. "You're right, but your attack just now was quite powerful. It could have instantly killed an opponent of the same level."

Leng Yuexi agreed and offered suggestions.

“That’s right, we haven’t encountered any opponents who are proficient in the spiritual realm before.”

That said, these two soul-binding techniques are actually quite useful. I suggest that the defensive techniques be passed on, but the offensive ones shouldn't be.

Qin Feng nodded, "That's what I think too. It's enough for the few of us who are close to know. We won't spread it around. At most, we'll tell Elder Deng and the others."

Having been tested by Qin Feng and Leng Yuexi, Yin Tiantian and Xiao Fan became very interested in this soul technique and began to cultivate it with great enthusiasm.

However, they arrived at the Heavenly Sword Sect not long after.

Many disciples of the Heavenly Sword Sect recognized Qin Feng and his group. Deng Tianning had even specifically instructed the disciples guarding the mountain to report immediately if Qin Feng arrived.

Not long after Qin Feng and his group arrived at the mountain gate, they heard Deng Tianning's hearty laughter.

"Haha, my young friends, we finally meet again."

Qin Feng smiled brightly, "We meet again, Elder Deng."

Deng Tianning was very happy to see them. "I just happened to have something to discuss with you. Old Zhou also wants to meet you. Come with me."

Qin Feng was somewhat surprised. "Looking for me? Is there something you need?"

Deng Tianning waved his hand, "No rush, let Old Zhou tell you, he'll understand better."
