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

"No wonder this coffin is so heavy. It's filled with wine! This Taoist priest actually used an unborn child to make wine. He's utterly depraved." After hearing Wang Zhenhuan's explanation, Ao Shuang used "surprisingly" three times in a row, and her face immediately turned cold.

"That's right. He also tricked Old Sun by promising him a long life so that he would make him brew medicinal wine," Wang Zhenhuan explained.

"So that old man Sun was bewitched, dreaming of immortality at home, and agreed? The resentment generated by the infant who died before birth is the strongest. How come he didn't go crazy?" Ao Shuang asked disdainfully.

"That evil Taoist priest appeared to him in a dream and came up with a solution: to build a coffin out of jujube wood and put the medicinal wine inside, thus isolating the resentful spirits," Wang Zhenhuan said, shaking his head.

"What a brilliant idea! Although that resentment contains spiritual energy, it's all yin-type spiritual energy. Isn't that Taoist priest afraid of going berserk after drinking it? Truly ignorant!" Ao Shuang sneered.

"It's probably soon. When I saw him appear earlier, he exuded a sinister aura, and his mental state seemed somewhat unstable. That's why I'm afraid he'll launch a night raid on the yamen tonight," Wang Zhenhuan explained.

"No need to guess, he'll definitely come. He's a weasel practicing evil arts, and he's even been ordained. I'd be surprised if he didn't dare to come. What do you plan to do?" Ao Shuang asked.

"Now that Chonghe Zhenren is not in the yamen and Lingzhizi is bedridden, only the two of us brothers are left. That evil Taoist is at the light blue cultivation level. If the elder brother fights him and the younger brother assists from the side, we may not be without a fighting chance."

"It's a pity that summoning the deity previously consumed a lot of spiritual energy, and now my spiritual energy is only enough for half a year. If my spiritual energy were abundant, we might be able to subdue it," Wang Zhen said with some regret.

"Subdue him? Hmph, he doesn't deserve it. If any member of our Daoist sect sees such an evildoer, they should all kill him. Think of a way to keep him here tonight. Otherwise, he'll only bring more harm to the people of Xiayi." Ao Shuang said in an icy voice.

He was an upright man, and also the river god of the Huai River. Protecting the people of Xiayi was his bounden duty, even though Wang Zhenzhen didn't know whether he was appointed river god by the Heavenly Court.

However, the people recognized him, and he himself was willing to be the river god. Since the Heavenly Court had not intervened, he was the river god of the Huai River, and no one could say anything against him.

"It would be difficult to keep it, but if it's a matter of life and death, then it's another matter. I heard Master Lu say that Master Chonghe once left a talisman at the mansion," Wang Zhenhuan said to Ao Shuang.

"What talisman? If it's a purple talisman, even if you and I wanted to use it, it would be quite difficult, right? To activate a purple talisman, one needs at least a blue-level cultivation level," Ao Shuang explained.

The term "purple talisman" does not refer to its color. Rather, it refers to talismans written by the Purple Qi Immortal, which are generally called purple talismans. Unlike the yellow talismans used in ordinary rituals, these purple talismans are imbued with a wisp of the writer's spiritual energy.

When used, it only needs to be activated to take effect, saving the steps of pinching fingers and chanting incantations. Moreover, its power is not much different from that of the person casting it. Only the Purple Qi True Man can write such a talisman.

"It shouldn't be some kind of powerful spell. According to Master Lu, the reason why Master Chonghe left this talisman was so that if any demons entered the town while he was away, it could protect the government office."

Therefore, I guess this talisman must be a protective spell. Only such a spell can be activated without requiring spiritual cultivation. Otherwise, what would be the point of the True Man leaving this talisman behind?" Wang Zhenhuan stated his guess.

"That makes sense. We're only staying at the yamen temporarily. This talisman should have existed for a long time. If what you say is true, it's very likely a protective talisman, like a barrier."

Ao Shuang looked at Wang Zhenhuan, slammed her hand on the table, and continued, "What are we guessing for? Why don't we just ask the clerk? He handles all the big and small matters in this mansion; he must know about this."

"Brother, don't be anxious. I had the same idea. If that talisman is indeed a protective talisman like a barrier, may I ask if you can trap that evil path?" Wang Zhenhuan waved his hand, signaling him not to rush.

"Of course it can. That's a purple talisman left by a true master. How could it not be able to trap him with a mere wisp of blue energy? This method is feasible. Let's go and find the master to ask him for clarification." Ao Shuang said, getting up and walking towards the door.

Wang Zhenhuan watched his hurried figure disappear into the distance, sighed, and followed. He hadn't yet asked what to do after trapping the Taoist priest. But that was a matter for later; first, he needed to determine the talisman's effect.

Both men possessed cultivation, so the darkness of night was no obstacle for them. They crept to the door of the advisor's room, where a lamp was still lit. Hearing the noise outside, he instinctively got up to open the door.

But remembering Wang Zhenhuan's earlier instructions, he hesitated for a few moments and was about to turn back when he suddenly heard Wang Zhenhuan's voice from outside the door: "Master, it is I. I have something I would like to ask you to verify."

"This... didn't the Taoist priest say before that I shouldn't open the door no matter what sound I hear? Should I go out or not?" Master Lu was also a little confused. It was Wang Zhenhuan who told him not to open the door before, but now it was him knocking on the door.

This left the advisor momentarily unsure whether to open the door. Wang Zhenhuan, hearing this, immediately laughed and said to the figure inside, "Advisor, you don't need to open the door. Just tell us."

"Alright, if you have any questions, please ask, Master Lu." Hearing this, Master Lu finally felt relieved and addressed the doorway.

"I'm sure you've heard about what happened tonight from Old Sun. Now that Master Chonghe is not here, I'm afraid that evil Taoist priests might attack the yamen at night, so I've come to ask you, Master, if the talisman left by Master Chonghe is still there?" Wang Zhenhuan considered for a moment, then told the truth.

"Yes, it's always been with me. I'm always afraid something might happen to the yamen, so I always carry it with me." Master Lu nodded, then, remembering that Wang Zhenzhen couldn't see it, he hurriedly spoke up.

Wang Zhenhuan and Ao Shuang, standing outside the door, exchanged a glance after seeing the shadow reflected on the door nod. They then asked again, "May I ask, Master, is that talisman a protective barrier or similar?"

"Whether it's a protective talisman or not, I, Old Lu, don't know. I only heard the Master instruct that if there are any powerful demons that try to attack the government office, activating this talisman will protect you."

Master Lu hesitated for a moment, then continued, "If there's nothing else, Master, I'll turn off the lights and rest."

"Don't rush, please open the door, sir..."
