"Go to design yourself? Well, let me think about it." Li Er began to think when he heard that Zhang Nan was going to supervise the construction himself.

Just as Li Er was thinking, Liu Bing's voice came from outside. "Report to the emperor, Master Yuyang is asking for a visit."

When Li Eryi heard that the Yuyang Zhenren was asking for a meeting, he didn't think about whether Zhang Nan would let him go to supervise the founder. Instead, he couldn't wait to say, "Come in quickly." When Zhang Nan heard that he was a real person, he also became interested. What kind of Taoist priest was this that could make Li Er so impatient.

After receiving Li Er's reply, the Yuyang Zhenren came in with a tray covered with red cloth. Zhang Nan looked at him. The Yuyang Zhenren looked like a fairy-like appearance. The Yuyang Zhenren walked to Li Er, and even Zhang Nan didn't even look at him, and bowed to Li Er on his chest. He said, "I'm here to see the emperor."

Li Er didn't care about these common etiquettes and couldn't wait to ask: "The real person is exempt from the gifts. I wonder how the real person has refined this elixir."

Master Yuyang bowed slightly and said, "I'm not disappointed the emperor's entrusted. The furnace of elixirs that I have refined this time is a top-notch. After these 49 days of refining, this furnace of elixirs has absorbed the spiritual energy of heaven and earth and the essence of sun and moon. Now is the best time to take it."

As soon as he heard Master Yuyang say this, Li Er smiled and said, "Okay, Master quickly presents the pills, I will take them immediately."

When Zhang Nan heard that Yu Yang Zhenren was an alchemist, he immediately understood that it was not without reason that Li Er lived long enough. He started taking this heavy metal pill at a young age. Li Er could live fifty years old, and Li Er was really healthy.

Master Yuyang put the tray on the desk, uncovered the red cloth, and said, "Prince, please see, these two pills are the Yin-Yang Immortal Pills refined by Weichen for the Emperor and the Empress. Eating them can strengthen your body and prolong your life."

When Zhang Nan heard this remark from Master Yuyang, he sneered. His eloquence was not as good as those who sold Dali Pills under the overpass.

Li Er also noticed Zhang Nan's appearance and asked strangely: "Qingquan, what's your expression?"

When Zhang Nan heard Li Er ask him, he quickly said, "No, Master, I wonder if this Yin-Yang Immortal Pill can be viewed by Rong Chen?"

When Li Er heard Zhang Nan want to see his elixir, he said generously: "Look, let's open your eyes, Qingquan, you will also open your eyes." Li Er always finds what he is interested in here. Now he finally has what Zhang Nan is interested in, and Li Er wants to show off in front of Zhang Nan.

After receiving Li Er's reply, Zhang Nan walked forward, picked up the so-called "Yin and Yang Immortal Pill" and put it under his nose and smelled it. As expected, this "Yin and Yang Immortal Pill" emitted a pungent smell.

Sulphur smell!

The alchemy technique in the Tang Dynasty was nothing more than something made by mixing various minerals and heating, distillation and other means, but Li Er still believed this thing.

"Hmph, Master Yuyang, let me ask you, who has been instructed to dare to murder the emperor and the queen?!" Zhang Nan put down the "yin and yang immortal pill" in his hand and suddenly asked Master Yuyang sternly.

When he heard Zhang Nan dared to speak to him like this, the Master Yuyang, who didn't even take the Duke seriously, was immediately angry. "Bastard, you are talking nonsense and slandering this real person."

When Li Er heard Zhang Nan say this, he frowned. After all, this Yuyang Zhenren is deeply loved by him, and he has this alchemy technique. His immortality is pointing at this Yuyang Zhenren. Now that Zhang Nan says this, Li Er frowned and said, "Qingquan, don't talk nonsense. This Yuyang Zhenren is an old acquaintance with me. Why did you come back to harm me? If you don't understand this alchemy technique, don't talk nonsense."

When he heard that Zhang Nan could not refine alchemy, Master Yuyang sneered and said, "What kind of art do I think I have? It turns out that I don't know how to refine alchemy at all. Forget it, I'm a real person who can't refine alchemy. This time, I'll pass by the adults and not remember villains."

When Zhang Nan saw that Yuyang Zhenren dared to pretend to be a fool in front of him, he immediately became angry.

"Master, dare to underestimate me." Zhang Nan cursed in his heart and said, "Who said I don't understand alchemy."

When Li Er heard that Zhang Nan actually said that he could refine elixirs, he immediately became interested.

"Oh, Qingquan actually knows how to refine elixirs, which makes me curious."

"I can naturally refine elixirs, and my elixir only requires a ingredient, which can be ten thousand times more effective than the bullshit "Yin and Yang Immortal Pills"." Zhang Nan said confidently.

When Li Er heard this, he was immediately overjoyed and said, "Oh, what kind of raw materials? I will send someone to prepare it immediately. Qingquan, you can refine it for me immediately. If you practice it well, I will have a lot of rewards."

"Xinshi." Zhang Nan smiled slightly and said.

This letter stone is the legendary crane red head, which is arsenic.

When Li Er heard this, his face turned dark and said, "Qingquan, what kind of pill did you practice with this Xinshishi?"

Zhang Nan said with a decent look on his face: "My pill is named the Leg-Slifting Eye Pill. Just take it, you can stretch your legs and stare in a few breaths and ascend in the sun."

Li Er said with a dark face: "Bastard, you are not a pill, it is clearly a poison."

"Oh, is that? Why do I think my elixir is not much different from the elixir of Yuyang Zhenren?" Zhang Nan said.

Hearing Zhang Nan say this, Li Er finally reacted and said, "You mean, this "Yin and Yang Immortal Pill" is poisonous?"

"That's right, it's indeed poisonous." Zhang Nan said.

"All nonsense is talking, the emperor, this person is really a witch that confuses the public. I ask for a heavy punishment for this person." Yuyang Zhenren said angrily.

When Li Er heard that Yu Yang wanted to punish Zhang Nan severely, he was immediately a little unhappy. If he was not punished, he had a decision and had something to do with you Taoist priest. So Li Er said, "Don't be anxious, it's not too late to wait until Qingquan finishes talking."

"Your Majesty, I am loyal and can be seen by heaven and earth. If the emperor doesn't believe it, I am willing to try the medicine with my body." After Yu Yang said that, without waiting for Li Er to agree, he reached out to pick up a pill and chewed it into his mouth. While chewing, he stared at Zhang Nan viciously, as if he had regarded the pill in his mouth as Zhang Nan.

"You are really ignorant and fearless." Zhang Nan looked at the appearance of Master Yuyang and secretly complained in his heart.

After the true man Yuyang swallowed the pill in his mouth, he said, "Your Majesty, I have finished the test of the medicine. Now, the emperor has made a decision in his heart. What a pity, it's a pity that there is only one pill left in such an immortal pill."

When Li Er heard this, he frowned and said, "Qingquan, what else do you have to say?"

Zhang Nan thought to himself: "How can this metal poisoning be so fast? It's not a rat medicine."
