After her rebirth, she became the sweetheart of the sickly uncle.

Only then did Su Qingcheng realize that after coming out of the palace, she seemed to have not gone to Su Yizhi and the fourth prince to talk about the emperor.

"I've been busy these days and forgot about it. By the way, brother, is the fourth prince here?" Su Qingcheng looked at Su Yizhi and said.

"He was originally here. He just went to the princess's mansion and he stayed there. He said he would come over later. Do you have anything to do with him?"

Su Qingcheng said: "Emperor Dong Ling faked his death, but he is indeed poisoned now and is in danger."

"I know that he faked his death, but what happened to the poisoning?" Su Yizhi said.

Su Qingcheng was a little surprised, but after thinking about it, there were many clues about Emperor Dongling's fake death.

"It's the queen. She wants to support the eldest princess to ascend to the throne." "Imitate Beiyuan?" Su Yi said subconsciously.

Among the Three Kingdoms, only Beiyuan has the theory of a female emperor. Back then, the Crown Princess Nanye almost became the first female emperor of Nanye, but it was a pity that fate played tricks on people.

Su Qingcheng said: "I guess so."

"Have you found the antidote?" Su Yizhi said.

"I'm working hard, but it's not ideal." Seeing Su Qingcheng's serious look, Su Yizhi knew the seriousness of the matter.

"If anything is not ideal, tell me about it to this prince."

Before the fourth prince appeared, the voice came out first.

He swaggered into the study, still looking careless. If Su Qingcheng hadn't known who he was for so long, she would have thought that he was just an idle lothario.

"Not long after the wedding, he left his beloved wife alone in the palace. King Yu Nan must not know how to show mercy to her."

It seems that the news of Ye Tantai returning to Nanye has been leaked...

"The fourth prince knows how to pity women. How can you take pity on the girls in the backyard?" Su Qingcheng asked.

"Hahaha, don't they all say that a woman becomes gentle after getting married? Why is she still so sharp-tongued?" The fourth prince seemed to be in a very happy mood and tapped Su Yizhi's shoulder with his folding fan.

Seeing that Su Yizhi didn't answer him, he realized that something might have gone wrong and said, "What's wrong? Did you tell her that Emperor Dong Ling faked his death?"

"She already knew," Su Yizhi said, "Not only that, she also knew that Emperor Dong Ling was poisoned."

"What?" The fourth prince immediately became serious, and Su Yizhi briefly introduced him to the current situation.

After a brief silence, the fourth prince took out a pill from the innermost part of his clothes and said, "Can you take a look at this?"

"This is..." Su Yizhi looked at the shape of this pill that looked very familiar. It was the one that the fourth prince saved him from when he was poisoned many years ago.

Su Qingcheng took it, her eyes gradually brightened. This pill was the Feng Shui Hunyuan Pill that could only be encountered but not sought.

It is refined from dozens of precious medicinal materials, and its effect can be said to snatch people from the hands of the king of hell.

"Where did you get this? Although there is no book that says Feng Shui Hunyuan Pill can cure Hell's Ganoderma, I think it is it." Su Qingcheng said.

"As long as it works, this medicine is very precious. I spent a lot of money to find two of them on the black market. One was given to your brother, and this is the only one left. They say that one is worth ten Nine-Turn Resurrection Pills. "The fourth prince breathed a sigh of relief when he heard that it was useful.

Su Qingcheng took the pills and held this hard-won treasure tightly in the palm of her hand.

She suddenly remembered Hao'er's illness. Although it was a bit nonsensical, she still asked: "What were the symptoms of the poison that my brother was poisoned back then?"

Su Yizhi said: "I am getting thinner and thinner day by day, and the high fever persists..."

While he was still reminiscing, the Fourth Prince answered quickly: "One more thing, he became ill suddenly."

Sudden onset of illness...

Really the same as Haoer.

Su Qingcheng became suspicious, but there was no definite evidence to prove the relationship between the eldest princess and Su Yizhi.

"You said you found this elixir on the black market. Can you still look for it now?" Su Qingcheng asked.

"Do you really think that this panacea is as easy to find as the steamed buns on the street? This prince has been waiting for many years to find this." The fourth prince said.

Su Qingcheng was disappointed: "Well, I'm too idealistic."

"I have been looking for someone to keep an eye on the black market these years. I will know it as soon as possible if it appears." Seeing her appearance, the fourth prince explained.

"I understand, I will take him to the palace tomorrow." Su Qingcheng said.

The matter was settled, Su Yizhi and the fourth prince left after not staying for a while.

"Wu Ya, call Yu Lan over." Su Qingcheng said.

There was no one in the study, and only the sound of the slight sound of tiles echoed in response to her.

After a while, Yulan walked in: "What do you want from me?"

"I've found a way to cure Hell's Ganoderma." Su Qingcheng's tone was brisk, and her tense mood for so many days finally relaxed.

Yulan was very surprised and said: "Where? Let me read that book!"

"It's not a book, it's this." Su Qingcheng handed it to her to read.

"Feng Shui Hun Yun Dan? It turns out that there really is such a thing in this world," Yu Lan said very curiously, "Lend me one night."

Su Qingcheng immediately took it back and said with some vigilance: "What are you going to do? This is something that was hard to get, so I won't let you take it back to Beiyuan."

"I just want to study its medicinal materials," Yulan said. "If I can know the raw materials of Feng Shui Hun Yun Dan and give it to the princess in the future, she will definitely praise me!"

Yulan was very excited.

As the envoys of Princess Beiyuan, the mission given to them from birth is to serve the princess and sacrifice everything for the princess, even their lives.

"You are sincere, but how do I know you won't take her and run away?"

Su Qingcheng actually planned to give the medicine to her, but she wanted to get the raw materials before the Beiyuan Princess could barely see her.

"Well, how about you let Wuya keep an eye on me? I can't run away with her martial arts skills so high." Yulan said.

Such a peerless miracle medicine is the ultimate temptation for a person who specializes in pharmacology.

Su Qingcheng pretended to be embarrassed, and after thinking for a moment, she said, "Okay, but I also want to be there."

"Deal!" Yulan said.

Only then did Su Qingcheng hand the elixir to her again.

That night, no one slept.

It was just dawn. After a night of research, Su Qingcheng looked at the page full of medicinal materials and was very happy.

Although this half page contains some extremely difficult to find medicinal materials, as long as Su Qingcheng knows the raw materials, she can cooperate with acupuncture treatment.

In this way, the emperor can be saved.

After Yulan finished writing, she immediately put the page away and said, "This is my meeting gift for the princess."

Wu Ya chuckled disdainfully and said, "Your princess may not want this thing."

"The Princess of Beiyuan is the most noble person in Beiyuan. It doesn't matter whether she wants these things or not. The most important thing is that she has them." Yulan said.

Su Qingcheng was suddenly curious about the identity of the princess, and said, "You always said that you can find the princess by finding Wu Ya, but how will you recognize her then?"
