"Poison..." Jiang Yi could hardly believe what she heard and kept muttering, "How could it be poison? How could it be poison..."

Could it be that the gentle and kind mother in my memory did not die of illness, but was murdered by someone?

She suddenly thought of something and grabbed Jiang Si's wrist, her voice changing: "What about grandma?"

My grandmother had the same symptoms as my mother. Since my mother died of poisoning, then my grandmother must have been poisoned as well...

Such a thought made Jiang Yi shudder.

Jiang Si glanced at the door and lowered his voice: "Sister, both my grandmother and mother were poisoned. I suspect the source is from the Yining Marquis Mansion!"

Jiang Yi's expression was shocked and became even more stunned.

After a while, she finally found her voice: "Fourth sister, why do you say that?"

Jiang Si's beautiful eyes narrowed slightly: "Since it is poison, it can't just come from the body. There must be someone who poisoned it. Sister, think about it, if the person who poisoned is from the Earl's Mansion, my mother has been dead for more than ten years, it is impossible for him to reach the Yining Marquis Mansion..."

Jiang Yi deeply agreed.

If a person could poison both his mother and his grandmother, he is most likely from the Yining Marquis's Mansion.

Her lips moved, wanting to ask Jiang Si how he could tell that her grandmother was poisoned, but she swallowed the words back silently.

Jiang Yi has always been a considerate person. If the other party doesn't ask about something, she won't ask.

"When mother passed away, my second aunt had not yet married into the family, right?" Jiang Si suddenly asked.

Jiang Yi was startled by the question, shook her head subconsciously, and then her expression changed: "Fourth sister, what do you mean--"

Jiang Si smiled coldly: "Although the person who poisoned us cannot be confirmed, at least we can rule out some people."

Even so, she already had some vague suspicions deep down in her heart.

Jiang Si stood up and walked towards the door.

Jiang Yi held her back and said, "Fourth sister, where are you going? Are you planning to report this to the police?"

Apparently, the shock at Baiyun Temple when her sister reported to the police at the slightest disagreement had left an unforgettable impression on Jiang Yi.

Jiang Si's tense face relaxed and he couldn't help but smile: "Big sister, am I that kind of person who likes to report to the police?"

Jiang Yi looked at her suspiciously.

She didn't want to hold her sister back, but she had no evidence and it was her maternal grandparents' house, so it was inappropriate to report to the police.

Besides, the fourth sister is the princess now, and reporting her to the authorities would be a laughing stock.

Jiang Yi was full of worries, but was so shocked by Jiang Si's words that she forgot all her worries.

"I'm going to find my grandfather!"

Jiang Yi hurriedly stopped Jiang Si: "Fourth sister, don't be impulsive. Grandfather is old and his emotions can't stand up to the ups and downs. Besides, although you can see that grandma was poisoned, you have no evidence and can't find the murderer. At least wait until you find some clues before revealing anything..."

"I can find evidence." Jiang Si looked determined. "Big sister, we can take it slowly. Grandma's health can't wait. How can we feel at ease if we don't find the person who hurt Grandma as soon as possible?"

That man is also the murderer of my mother!

Thinking of this, Jiang Si felt so angry that his teeth itched.

If her mother had not died, she would not have been so sensitive and inferior in her previous life, making one wrong choice after another.

If my mother hadn't died, my father wouldn't have lived alone and lonely in his old age, and my brothers and sisters might not have suffered those misfortunes.

Jiang Si admitted that these were all assumptions, but it could not stop her tremendous hatred for the person who poisoned her.

She must find this person!

"Fourth sister, can you really find evidence?"

Seeing Jiang Si nod, Jiang Yi's expression changed several times, and finally let go of his hand: "Okay, let's go together."

Old Marquis Yining was still squatting in the corridor smoking a pipe, and he started coughing while smoking.

Jiang Zhan patted him on the back and advised, "Grandfather, please smoke less."

The old Marquis of Yining glanced at his grandson and handed him the pipe: "Want a puff?"

Jiang Zhan hesitated for a moment, then took the dry pipe and put the mouthpiece to his lips, imitating the old Marquis of Yining.

He had never smoked this thing, but it was nice to make his grandfather happy.

Just as I was thinking this, a gentle voice came: "Grandfather, second brother——"

Jiang Zhan threw the tobacco bag in his hand away.

"Ahem, are you feeling better, fourth sister?"

Old Marquis Yining looked at the cracked emerald mouthpiece of the dry pipe that had fallen to the ground, and his beard trembled with pain.

When he was upset, he relied on this treasure to relieve his boredom.

Jiang Si came to the old Marquis of Yining, picked up the tobacco bag and handed it to him.

Old Marquis Yining took it and wiped off the dust. He said in a desolate tone, "After visiting your grandmother, go back early."

"Grandfather, I have something to say to you." Jiang Si said softly.

Only then did the old Marquis of Yining raise his eyelids and look at Jiang Si.

This granddaughter is the one who most resembles the daughter who died young.

In a blink of an eye, it has grown this big.

The old Marquis Yining's eyes became a little gentler, and he asked, "What's the matter?"

"Please go to where I just rested."

Before the old Marquis Yining could respond, Jiang Zhan helped him up: "Grandfather, I'll help you over."

"I don't need your help." Old Marquis Yining hit Jiang Zhan on the back of his hand with his tobacco bag and said unhappily.

This silly boy is on the same page with his sister.

Jiang Zhan was not annoyed and just grinned.

Returning to the house, Old Marquis Yining put his pipe on his waist and looked at Jiang Si.

"Grandfather, please sit down first." Jiang Yi helped the old Marquis Yining to sit down.

What the fourth sister was about to say was too shocking, so she let grandpa sit down first.

Old Marquis Yining felt something was wrong and looked at Jiang Si with frown.

In the eyes of others, this girl is a princess, but in his eyes, she is still that little granddaughter. If she makes trouble, he will definitely scold her.

"Grandpa, I visited grandma today and discovered something."

"What is it?"

"Grandma is not sick, she is poisoned."

"Say it again!" Old Marquis Yining changed his previous senile demeanor and a gleam of light flashed in his eyes.

Jiang Zhan looked stunned.

Jiang Sisi did not dodge and repeated firmly: "Grandma is not sick, but poisoned!"

The old Marquis of Yining stared at Jiang Si with a burning gaze, and said in a sharp voice, "Fourth girl, do you have any basis for what you said?"

"My grandmother's body is my basis. I can force the poison out, but my grandfather has to help me."

Old Marquis Yining regained his composure and asked in a deep voice, "How can I help?"

Jiang Si looked towards the door and spoke word by word, "I want to find the person who poisoned me. Grandfather, please call all the elders in the mansion together first."

"You mean... the person who poisoned is among these people?" Old Marquis Yining was shocked, with suspicion in his eyes.

Jiang Si said calmly, "My mother's symptoms were the same as my grandmother's. Who do you think is most likely to have poisoned her?"

Old Marquis Yining was stunned for a moment, anger surging in his eyes: "I'll tell them to come over!"

"No, please let them all go to their grandmother."

Soon, a lot of people gathered outside the old lady.

Uncle Su looked inside and said to the old Marquis Yining, "Father, mother is asleep. We will disturb her if we are all here."
