It's good to exchange marriages. My sister eats coarse food while I wear gold and silver.

"It's normal for a family to have such thoughts after it has existed for too long, especially for more than three generations. All the families in Dazhao that have existed for more than a hundred years think this way." The old woman seemed very calm. "I originally calculated the day of my death, but I didn't die. I calculated again and found that I still had something to do, so I came here. As for the poison this time, it's actually not a poison."

"what is that?"

"It's a phantom poison."

"Illusion?" Yuan Buwei asked. "There are many craftsmen in the folk who use illusion to make a living."

"Unlike illusions, phantom poison causes mental confusion, but the body is actually poisoned. Should you extract their blood for analysis?"

As expected of a member of the Dugu clan, Yuan Buwei didn’t say anything, but the old woman guessed everything.

"Yes, I still have only a limited understanding of it." Yuan Buwei said truthfully, "My two senior sisters and I have tried every possible way, but we are unable to break this poison."

"Since it is an illusory poison, there is no need to take an antidote."

"No need to take the antidote?" Yuan Buwei was a little confused, "But the symptoms of those patients are real."

"You medical students must think that all diseases are caused by external factors. In fact, all diseases are caused by emotions. Moreover, the human body can heal itself without taking medicine. However, these are off-topic. If you are interested, I will tell you about the solution later." The old woman looked at everyone, "Who here can play the flute?"

"We can't play the flute, but we can find one."

"This flute player is not an ordinary flute player. His birth date and time must be in a yin month, yin day and yin time. And the flute he wants to play needs this bone flute." The old woman took out a short bone flute from her bosom while speaking. "This bone flute recognizes its owner. It doesn't mean that this person can play it just because he was born in a yin month, yin day and yin time."

"I'll send someone to look for him right now." Wan Ninghou stood up and said seriously, "Senior Dugu, leave this matter to me. I will definitely help you get it done. By the way, does this flute player have any requirements for men or women?"

"Men are best."

"clear."

"Old lady, is there anything you need that we can do for you?" Yuan Buwei asked.

"No need. Now we can only wait. And I calculated that this person is in the capital." The old woman said with great confidence.

Since the old lady said so, Yuan Buwei notified the two senior sisters to take a break. After being busy for so long, the two of them could finally take a break.

But things did not go smoothly.

Marquis Wanning gathered almost all the men, women, young and old who were born on the yin month, yin day and yin time in the capital and asked them to play the bone flute. Among them was an expert who had played the flute for many years, but he couldn't make the bone flute sound.

"Senior Dugu, did you make a mistake in your calculation? Maybe this person is not in the capital? Or maybe this person has passed away?" Seeing that old lady Dugu did not speak, Wan Ninghou immediately said, "I went directly to the government office and checked every household according to the government's household registration book. I made sure that no one was missed. I even brought a three-year-old child with me."

"No, there should be one more."

"There's another one?" Wan Ninghou scratched his head, "Then I'll go find it now."

Just as Marquis Wanning turned around and was about to walk out of the yard, Lu Sui, who had not been home for a long time, heard that a solution had been found and took time to come back.

"Father, where are you going?"

"Oh!"

Wan Ning Hou stopped and said, "I only looked for civilians in the city. There are many people in the military camp. Maybe the people of Yin Yue Yin Ri Yin Shi are in the military camp? Yes, I will go to the palace to find the emperor now. No, if I go to the palace and tell the emperor about this, then the emperor will know that there are still people alive in the Dugu family. Oh, I have to go to the Swift Wind Camp first."

"Hey, father, what are you doing at the Gale Camp? Do you want me to go with you?" Before Lu Sui could finish his words, Marquis Wanning disappeared.

It was the first time that Lu Sui saw his father in such a hurry. He touched his head and walked into the yard.

"Avi."

The moment he saw Yuan Buwei, Lu Sui immediately ran towards her: "How have you been these days?"

"I'm fine, why are you back?"

"I came back to see you." As Lu Sui was speaking, he felt someone staring at him. He turned around and saw an old woman. "Who is this?"

"Lu Sui, let me introduce you. This is the Dugu clan member I met after I fell into the cave."

"So you are the old lady that Awei mentioned." Lu Sui bowed hurriedly, "Junior Lu Sui, greetings to Senior Dugu."

"You are Lu Sui, the son of Marquis Wanning?"

"Yes."

"When is your birthday?"

"Um... August 7th."

"August 7?" The old woman lowered her head and calculated, then shook her head, "No, that's not your birthday."

"Old lady, even if my brain is not working well, I will not forget my birthday wrong, right?" Lu Sui suddenly felt that the old lady in front of him was a little weird.

"Come, play this bone flute." The old woman handed the bone flute to Lu Sui without explaining.

"What? I can't play the flute." Lu Sui was puzzled, his eyes full of vigilance.

"This flute is not poisonous. It has been disinfected. It is very clean. Just blow it."

Lu Sui was stunned for a moment and turned to look at Yuan Buwei.

Although Yuan Buwei didn't know the old woman's intention, she thought for a moment and said, "Lu Sui, just blow it. It's okay."

"Oh."

Lu Sui listened to Yuan Buwei's words. He took the bone flute and thought for a moment: "How do you play this flute?"

"Put this mouth to your lips and blow into it."

"Oh."

Lu Sui was good at wielding swords and guns, but he knew nothing about playing musical instruments. But the amazing thing was that he just blew a breath into the air port.

The flute, which had not been played for several days, suddenly made a pleasant sound like the sound of nature.

Lu Sui was dumbfounded.

Yuan Buwei was shocked.

The old woman smiled.

"found it!"

"No, I don't know how to play the flute at all. How could I possibly make the flute sound? Am I gifted?" Lu Sui looked left and right at the flute in his hand. He didn't believe that he could play it, so he tried again, but the result was the same.

"I said, your birthday is wrong."

"How could my birthday be wrong? When my father comes back, I will ask him about it. Who would get their child's birthday wrong?" Lu Sui was furious. "But what's the point of me blowing this flute?"

The old woman smiled slightly and said, "For this incident in the capital, we need this bone flute in your hand to awaken the consciousness of those who have been poisoned."

"I?"

Lu Sui pointed at his nose. He always fantasized that he could become a savior one day.

I didn't expect it to come so soon.
