Hearing Su Hexun say this, Yu Beixuan suddenly became uncertain, after all, he had never tasted the poison of the Immortal Realm.

"Why don't we give it a try first? Does Fellow Daoist Su have any poison on him?"

Su Hexun hesitated for a moment, then handed over a small porcelain bottle: "I have a bottle of mute medicine here. One pill inside can make an Earth Immortal mute for three years."

Yu Beixuan took the porcelain bottle, pulled out the stopper, and without hesitation put one into his mouth.

He felt it was fine that they hadn't spoken for three years. With the Daoist contract in place, communication between him and Er'er was not an obstacle.

He doesn't have much trouble communicating with others, unless he deliberately blocks them. Otherwise, his soul pets are all on the same page with him and can speak on his behalf.

After swallowing the pill, Yu Beixuan asked, "By the way, when will this pill take effect?"

Su Hexun hesitated and said, "Should it be now?"

"Now?" Yu Beixuan shook his head. "I don't feel anything. I don't feel any discomfort in my throat at all."

Su Hexun explained, "My medicine is only meant to calm the mind, not to make you feel uncomfortable, so it's because Fellow Immortal Yu doesn't feel anything in your throat."

But it's abnormal if he can still speak normally.

Si Er laughed and said, "It seems that this mute medicine has no effect on Xuanxuan."

Yu Beixuan said cautiously, "Let's take another look. What if the effect is delayed?"

"By the way, Fellow Daoist Su, besides the mute medicine, do you have any other medicines?"

Su Hexun pulled out another bottle: "One of these can make you deaf for three years."

Yu Beixuan took it and swallowed another one without hesitation.

After swallowing it, he asked, "Is this also effective immediately?"

Su Hexun said helplessly, "That's how it is under normal circumstances."

However, he felt that Yu Beixuan was not quite normal.

Yu Beihu perched on Yu Beixuan's shoulder, tugging at his ear and blowing air into it. Yu Beixuan scooped it up and placed it on Yu Beilang's back.

"This is a pill that temporarily causes deafness. What do you mean by pouring air into my ears?"

Upon hearing this, Yu Beigui quietly emerged, perched on Yu Beixuan's other shoulder, and began to sing loudly, "So hungry, so hungry, so hungry, I'm really so hungry..."

Yu Beixuan skillfully stunned the Yu Bei Turtle and threw it into the Soul Pet Space.

Guagua laughed heartily: "Hahaha, only the little turtle hopes that Xuanxuan really goes deaf, so that it can sing loudly for the next three years."

Si Er also found it amusing: "It seems that Little Turtle is destined to be disappointed. Xuanxuan doesn't seem to have any reaction after taking the medicine."

"Right, Xuanxuan? Don't you think my voice is softer now?"

Yu Beixuan shook his head: "No."

Si Er then looked at Su Hexun: "Fellow Daoist Su, do you have any other poisons you can try? Do you have any with a slightly larger dosage?"

He felt that these medicines might not be considered poisons, but rather more like pranks.

Su Hexun then pulled out a small medicine bottle: "This one is a bit more potent; it can blind an Earth Immortal for a hundred years."

"This does sound a bit serious," Si Er hesitated. "Xuanxuan, do you want to try it?"
