The Northern Song Dynasty returned south, seeking the truth of the Dao.

Upon hearing Ao Shuang's words, Wang Zhenhuan was taken aback. He then shook his head and replied affirmatively, "That's right, I saw it with my own eyes. Judging from the woman's attire, she should be a servant in the household."

"Hiss—that's strange. As far as I know, Old Man Chen did indeed dismiss all the servants in his household three years ago. When I came here, I was wondering why such a large Chen mansion didn't have a single servant." Ao Shuang was also puzzled.

"Three years ago? What was the purpose of your visit to the Chen residence, elder brother?" Upon hearing his words, Wang Zhenhuan subconsciously asked.

"Ahem, it's a personal matter, a personal matter. My turtle treasure is lost, I'll go look for it." Ao Shuang coughed awkwardly a few times and waved her hand.

Seeing his expression, Wang Zhenhuan immediately understood. What "looking for Guibao"? He must have gone to meet with that Miss Chen. However, Ao Shuang's words also indirectly confirmed what he had said earlier.

This is strange. Since Chen the Benevolent had already dismissed all his servants, who was the one who opened the door for Wang Zhenhuan earlier? If it wasn't a servant, then it could only have been a member of Chen the Benevolent's family.

But Ao Shuang just said that the entire Chen family died in that immortal's cave. So, is the woman who opened the door a human or a ghost? Wait, a ghost??

Wang Zhenhuan and Ao Shuang simultaneously looked up at each other. Wang Zhenhuan spoke first, "Brother Ao, what are you thinking about?"

"If you're not mistaken, that woman isn't human," Ao Shuang said after a moment's hesitation.

Wang Zhenhuan nodded: "That's what I thought too. If it's not human, then it must be a ghost. But at the time, I didn't sense any yin energy from her."

"The lack of yin energy isn't anything new. Since she can open the door, it means she has a physical form. Since she has a physical form, she shouldn't be a ghost or some other intangible yin entity." Ao Shuang shook her head.

"If it's not a ghost, then what is it?" Wang Zhen asked, puzzled.

"We'll only know what it is after we see it. As far as I know, there are quite a few yin entities that don't show any yin energy. Like zombies, or disguised ghosts, and so on," Ao Shuang explained.

Upon hearing Ao Shuang's explanation, a thought suddenly popped into Wang Zhenhuan's mind. He looked up at Ao Shuang and asked somewhat uncertainly, "Brother Ao, can these Yin creatures awaken memories of their past lives?"

"Demons with painted skins should work, but zombies won't. Zombies are essentially different people, just using the same body. Ghosts are the opposite. What? What came to mind?"

Upon hearing Wang Huanzhen's question, Ao Shuang immediately became interested. He knew just how capable his adopted younger brother was. It wouldn't be an exaggeration to say that he was almost demonically intelligent.

Before he could even finish explaining the location of the cave, Wang Zhenhuan had already guessed the truth. From then on, Ao Shuang was utterly in awe of his intelligence.

"If I'm not mistaken, that woman is very likely Chen Shanren's wife. And the reason he ignored Miss Chen's advice and insisted on going down into this cave is probably because of this," Wang Zhenhuan said, stroking his chin.

"You mean, there's something in that cave that can revive the dead? That's why Old Man Chen went down there at all costs, just to find that thing?" Ao Shuang continued, picking up where he left off.

"That's right! Why was Chen Shanren unmoved even when Miss Chen threatened to hang herself? Because he believed that the treasure in that cave could bring her daughter and wife back to life!"

That's why he disregarded everything, even dismissing all his servants, just to prevent the news from leaking out! But he didn't expect... Wang Zhenhuan revealed his thoughts in full.

"What he doesn't know is that this treasure for resurrecting people doesn't actually bring the dead back to life," Ao Shuang said, slapping her thigh and pointing at Wang Huanzhen.

"Yes! I wonder if you've ever heard of such a treasure, brother? It can bring the dead back to life in the form of a spirit object." Wang Zhenhuan nodded and then asked.

Upon hearing Wang Huanzhen's question, Ao Shuang frowned and pondered for a long time. Then, in a somewhat uncertain tone, she said, "As far as I know, there should only be one kind of treasure that can have this effect."

"What is this thing? Have you ever seen it, brother?" Wang Huanzhen pressed.

"It's a treasure called the Soul-Stabilizing Stone. I heard about it from others when I was little in Dragon... I answered subconsciously, but realized I had misspoke halfway through and quickly corrected myself."

Wang Zhenhuan overheard everything. If he wasn't mistaken, Ao Shuang was referring to the Dragon Palace. It seemed Ao Shuang's status was even higher than he had imagined. Only direct or collateral relatives of dragons could live in the Dragon Palace when they were young.

However, he did not ask. Since Ao Shuang had changed her mind, she obviously did not want to mention this matter, and he would not make a fool of himself by reopening someone else's wounds.

"May I ask, elder brother, what is this Soul-Stabilizing Stone? Why have I never heard of it before?" These thoughts flashed through Wang Zhenhuan's mind, but on the surface, he seemed not to have heard his earlier change of address, and continued to ask.

"The Soul-Stabilizing Stone is formed from the eyes of the ancient, exotic Zhulong after its death. Legend has it that this Soul-Stabilizing Stone can connect the Yin and Yang of heaven and earth and resist the limits of life and death," Ao Shuang explained.

"How did you do that?" Wang Zhen was genuinely curious.

"I don't know either. I've only heard that the Soul-Stabilizing Stone consists of two parts, Yin and Yang. The Yang stone can protect the physical body from harm, while the Yin stone can protect the soul from injury. Based on what you just said, the only one I can think of is the Yin-attribute Soul-Stabilizing Stone," Ao Shuang explained.

"Sir? I've bought the food. Shall I bring it in?" Xiao Liu's voice suddenly rang out from outside the door. Wang Zhenhuan got up and opened the door. After taking the food, he smiled and nodded to him.

"Let's eat something first, and stop thinking about it. Later, my brother and I will go to the Chen residence together and take a look. Then everything will be clear. I just don't know what it means to have an unharmed soul," Wang Zhenhuan said.

"We'll see when we try. Come and eat. It's really a headache. To be honest, I hate thinking the most. If it weren't for this cave dwelling matter constantly on my mind..."

"Brother, I went back to my Blackwater Pool to sleep a long time ago. It's getting colder and colder, who wants to go out?" Ao Shuang complained.

"Brother, isn't this a case of the capable taking on more work? Besides, when the opportunity arises, one should always seize it," Wang Zhenhuan said, pouring him another cup of wine. The more time Wang Zhenhuan spent with Ao Shuang, the more he realized this.

As expected of a tortoise, even in human form, his nature remained slow. Slow-paced people are generally easy to get along with and not particularly cunning.

The two chatted and drank until sunset. Looking at the almost empty table, Wang Huanzhen wiped his mouth and looked up to ask, "Brother, when shall we depart?"

"Let's go, let's go now! To the Chen family!"
