After leaving the hall, Su Yu had someone investigate who Su Zhen had met in the past two days, and sure enough, they found out about Su Liluo.

Thus, his resentment towards Su Liluo reached its peak.

Especially when he thought about how she had been raised under his name and had called him "father" for more than ten years, yet now she had ruined them like this.

Not only did they cause his wife to die, harm his daughter, and ruin his son, but they also took advantage of his misfortune!

She's determined to fight me to the death!

As long as Su Liluo lives, there will never be a good day for the second branch of the family!

Disappointed, he went to the old lady's courtyard, and together with Su Lianwu, the three of them discussed again how to kill Su Liluo.

They believed that only if Su Liluo fell would their second branch of the family have a good life.

They were already almost driven to the brink of despair, and they had been behaving themselves for so long without provoking Su Liluo, yet in the end she still tried to mess with them at every turn.

In that case, they might as well take the initiative.

"Mother, this whole thing is that wretched girl's fault for telling my eldest brother the truth beforehand. Otherwise, he would have believed us. She's an obstacle for us!"

As long as she's around, we, the second branch of the family, will never have a good life. I don't know why she's so jealous; after all, I've been called "Dad" by her for over ten years!

Su Yu sat on the stool and told Old Madam Su the results of his investigation.

When Madam Su heard that it was because of Su Liluo that their plan had failed and that her twenty taels of silver had gone down the drain, she was so angry that her wrinkled old face trembled.

"What a slut! A slut! Just like her mother! She seduces men with her looks. If she didn't have men backing her up, would she dare to be so arrogant?"

Madam Su cursed incessantly, her face displaying malice.

In her opinion, Su Liluo's success today is entirely due to her marriage to the Crown Prince. With the Crown Prince's backing, she dares to bully their second branch of the family like this.

If she hadn't had such a seductive face that captivated the Crown Prince, how could she have such a good life?

Hearing the old lady Su's scolding, Su Yu suddenly recalled the stunning beauty of that woman from back then.

Yes, Jiang Ruan was a stunning beauty back then!

He was actually amazed when he first saw his older brother bring her back. At first, he treated his sister-in-law very well and took care of her in every way when his older brother went out to fight.

Therefore, Jiang Qinshu was quite jealous back then, which is why she disliked Jiang Ruan very much.

Later, Jiang Qinshu poisoned Jiang Ruan without my knowledge; if I had known, I would definitely have stopped it.

But the person is already dead, so what can be done?

Moreover, Jiang Qinshu confidently explained to himself that he did this so that their daughter could become the Crown Princess and then the Empress.

The thought of potentially becoming the emperor's father-in-law blinded him to the allure of power and wealth, and he agreed.

"Yu'er? What are you thinking about?"

At this moment, Madam Su realized that after she finished speaking, Su Yu was standing there in a daze.

Su Yu shuddered, then came to her senses. "Huh? Mother, what did you just say?"

Seeing Su Yu's absent-minded look, Madam Su's face flashed with impatience. "Are you thinking about that slut Jiang Ruan again? It's been so many years, and you're still thinking about her?"

She knew that her son had been infatuated with Jiang Ruan's beauty back then, and her daughter-in-law Jiang Qinshu had complained about it to her many times.

She herself was of average appearance, so she disliked women like Jiang Ruan, who were beautiful, elegant, and popular with men, just like Jiang Qinshu.

Especially since Jiang Ruan is already married to the eldest son and pregnant, she still manages to make her own son infatuated.

"No, no, Mother, don't overthink it."

Su Yu quickly shook his head in denial.

He knew his mother didn't like Jiang Ruan, but he didn't expect that his mother knew him too well. Seeing Su Yu's denial, the old lady knew that she had guessed correctly.

She sighed in disgust, wanting to curse him a few more times, but then Su Lianwu suddenly asked curiously, "Grandmother, who exactly is the Crown Princess's mother? Where is she from? How come we haven't seen her family for so many years?"

"What family does she have? She's just a female healer that bastard brought back from the Northern Desert. I heard she was an orphan from a young age. Somehow she saved his life on the battlefield, which is why he insisted on marrying her."

If he hadn't already been showing when he brought her home, I would never have let that bastard marry her as his legal wife.

With that unfilial son's looks and achievements back then, marrying any daughter of an official wouldn't have been a problem. He might even have been able to help our Su family. Unlike her, who only knows how to seduce men with her beauty."

Mentioning this, Madam Su's face showed disdain, completely forgetting that she had once climbed up from an even more lowly concubine.

By using her various charms and wits to win over the master's heart, she managed to persuade him, who was completely infatuated with her, to elevate her from a concubine to the status of the principal wife after the death of the principal wife, risking ridicule.

As Su Zhen's nominal legal mother, she had the right to choose a wife for him. She had even considered using this opportunity to marry him a wealthy and powerful daughter of an official, hoping to help her son.

But who knew that the unfilial son was not only stubborn, but also got her pregnant. A general who had not yet married brought back a pregnant woman. Which young lady would be willing to marry him?

Therefore, his idea had to be abandoned.

"Northern Desert? Does Grandmother mean that my eldest aunt is a woman from the Northern Desert?"

Su Lianwu immediately grasped the key point in the words, his brows furrowed, and he hurriedly pressed for more information.

"I think so. I didn't ask for more details. I was so angry back then. He had such good qualities, yet he married a woman of such low status."

Later he went to war, and he handed over the reins of the household to her. Fortunately, he lost the war, otherwise—”

"Wait, Grandmother, did you just say that Uncle lost the war after he married Aunt?"

Before Madam Su could finish complaining, Su Lianwu looked at her excitedly and pressed her for an answer.

Madam Su looked puzzled and nodded blankly, "Yes, is there a problem, Wu'er?"

Suddenly, Su Lianwu excitedly stood up from his seat and looked at Old Madam Su and Su Yu with a joyful expression.

"Father, Grandmother, I know how to deal with the Crown Princess!"

How to deal with it?

Su Yu also looked at his son with curiosity. Seeing his son's joyful and confident appearance, could it be that he had really thought of a good idea?

Su Lianwu calmed his agitated emotions before speaking seriously, "Father, if Su Liluo is found to be a spy for the Northern Desert, do you think she can still remain the Crown Princess?"
