Reborn as a concubine's sister, the eldest lady went crazy

When Xu Yixing returned home, he was immediately called to the study by his father. Recently, his father always liked to see him in the study, but avoided Gu and rarely went to the main room.

"Yan'er, what happened? Tell daddy quickly!" Old Man Xu seemed a little unwell today, but Xu Yixing couldn't tell what was wrong.

"I'm fine, Dad. Today in the Sun Mansion, my sister might have been too sad and wanted to scratch my face, but fortunately, His Highness the Seventh Prince reacted quickly and stopped her in time. Dad, my sister now... seems to be a little crazy."

Xu Yixing only said that it was the Seventh Prince who saved him, and did not reveal anything about the dagger and the nails. After all, Yi Yan didn't know any fighting skills, and if he told his father about it, his father would inevitably become suspicious.

Old Man Xu stared at her face for a long time, and only felt relieved after confirming that there were no scars. He paced back and forth by himself, looking anxious, but said nothing.

Old Man Xu walked away for a long time, as if he had made up his mind. Suddenly, he nodded heavily. Xu Qian received the signal and left the room, leaving only the father and daughter in the room.

"Yan'er, I've thought about this for a long time, so I'd better tell you. Otherwise, I won't be at peace."

Seeing how serious he was, Xu Yixing couldn't help but become nervous as well.

"When you went to see your sister today, did you feel anything strange?"

There are so many weird things... I don't know how my dad knew about it.

"Well, my sister's temper has become very strange, she is irritable and violent. I saw that the uncles who used to serve my father were driven out of the yard by my sister. And sister Siwen also seemed to be not in my sister's yard. I didn't see her."

Old Man Xu sat back behind the table, not at all surprised by his second daughter's discovery.

"Yan'er, you are the most attentive. In fact, I was in your sister's room the day she got into trouble last time. I saw right away that the person was a fake and not my type at all. I suspect your sister has been killed by the Sun family, and this person is just an imposter!"

"Ah?" Xu Yixing shouted, with an expression of great surprise on his face. He was not pretending, he really didn't expect that his father had discovered the clues so early, and he could still endure it until now. Shouldn't it be a matter of seconds?

"But, but..." Xu Yixing was still organizing his words in his mind, but he had already recalled many things in his heart.

For example, what his father said, "I only have one daughter"; for example, he cut off all contact with the counterfeit after that; for example, he allowed himself to test the counterfeit.

Xu Yixing was confused again. She finally accepted her father's utilitarian and cold character, but suddenly realized that it was because her father had discovered the fake one early on and deliberately distanced himself from her.

Should she be happy about this? Is she happy that her father still loves her but not Yi Yan?

"Dad knows it's hard for you to accept this for the time being, but think about that person carefully. Is she really your sister?"

It's just hard to accept that you knew this all along.

Xu Yixing lowered his head and then raised it again, his face now showing an expression of sudden enlightenment.

"Then Dad, since you already found out, why did you let me visit you?"

Old Man Xu picked up a book on military strategy from the desk, but did not open it. He just crumpled it in his hands.

"I'm sorry, Dad. I didn't expect that person to be so cruel and crazy that he dared to attack you directly. I always thought that you went to check on them from time to time to calm them down and let them think that we didn't find any mistakes. But I didn't know that this would make them want to harm you. Alas!"

Using Yi Yan's safety to stabilize the Sun Mansion... Dad is really biased.

"Then, has something really happened to my sister?" Xu Yixing raised his eyes with expectation, but in fact, he was not at all moved inside. If his father had found his body earlier, he would have definitely made a fuss, and there would be no need to endure it so much.

"It's more likely to be bad than good. After the last time, I asked your uncle Xu Qian to search secretly, but there was no result. No one can find the person alive or dead. It's really worrying!"

"Dad, what should we do next?"

"Alas! Since the Sun family dared to use this method to replace your sister, they must be sure that we can't prove that she is fake. It is probably not a good idea to expose her rashly."

Well, they are indeed father and daughter, and they think the same as I do. Now Nanny Bai is dead, and Si Wu, who knew the truth, is also dead. Si Wen and the guards are still alive, but I guess they don't know anything and are of no use.

"Those bastards in the Sun Mansion thought they could tie me to their pirate ship like this? No way! The emperor hasn't even passed away yet, and old bastard Sun is already thinking about supporting the crown prince and becoming an important official in the new dynasty. Ugh! An old bastard!"

Dad couldn't tell whether he was talking to himself or talking to himself, but there was still some substance to what he said.

Yes, old bastard, the little bastard born from the old bastard!

"Ahem, Dad, let's talk business."

"Oh, that's right." Father Xu put down the book that had become waste paper and came back to his senses. "Yan'er, since there is no way to prove that the Sun family killed someone, then just kill them all!"

Oh my? Isn't this the same as what I thought? Xu Yixing was so happy that he almost slapped his thigh. They are really like father and daughter, and they understand each other.

But she thought of something else, bit her lip, and asked, "Dad, you don't want to lead your troops to attack the Sun Mansion directly..."

"Your father has no intention of rebelling. Besides, now that you have found such a good marriage, Dad doesn't want to endanger the lives of the whole mansion."

That's good, that's good. I was most afraid that my father would act impulsively. It seems that Xu Yixing was too naive and thought that his father was really an old man. It turns out that he has brains.

"Yan'er, for your future and your sister's revenge, you should get married to the Seventh Prince as soon as possible. She must have intended to disfigure you and make you lose the engagement by harming you today. Dad will never allow anyone to ruin this!"

Dad reacted quickly and figured it out immediately. This was exactly what Lu Anyuan said.

"This is entirely up to Dad."

"Okay, okay. When you marry the Seventh Prince, our family will naturally fully support him. When he ascends the throne, it will be your day to come to the fore!" Old Man Xu said this with excitement, his eyes reddened, as if he had already seen the scene of that day.

"But father, you are not placing all your hopes on the seventh prince, are you?" One in seven, this probability is definitely not high.

"How could that be? Just help your husband. Your father will have his own plans for your sister."

Hearing what my father said, he must have already made a plan. It's a pity that he won't tell his second daughter. Xu Yixing asked several times, but got no results, so he stopped asking. It doesn't matter what happens. Anyway, everyone has the same goal. At most, they can help each other. Are you afraid that you can't bring down a Duke's Mansion?
