The old lady of Yining Marquis' fingers were as thin as dead branches, and her nails were a little thick and had an unhealthy grayish-white color.

What caught Jiang Si's attention was not this, but the three faint red lines on the old lady's middle finger nail.

The three red lines fell into Jiang Si's eyes, which was particularly shocking.

She stared at that spot thoughtfully for a moment.

Noticing that Jiang Yi was distracted, Jiang Yi looked down subconsciously and was also stunned when he saw the three red lines on the old lady's nails.

The old lady moved her hands and asked Jiang Yi, "Yier, are you all right in the Bo's Mansion?"

Jiang Yi quickly retracted his gaze and smiled at the old lady: "Don't worry, I am living well at home, and Yanyan is also adapting well..."

"Grandma, what's wrong with you?" Jiang Si asked.

The old lady paused for a moment, then smiled at Jiang Si: "I'm old now, and I'm not very strong anymore. You don't have to worry about me..."

Uncle Su said, "Let the old lady have a rest."

Seeing that the old lady was really tired and weak, Jiang Yi pulled Jiang Si up and said, "Grandma, you should take a good rest. We will come back to see you later."

The three siblings followed Uncle Su and others to the flower hall, feeling quite heavy-hearted.

The condition of the old lady of Yining Marquis made people think of the phrase "old age with a candle in the wind".

The fire of life seemed to be extinguished by a slight breeze.

"Uncle, what disease does my grandmother suffer from?" Jiang Zhan was an impatient person and asked as soon as he entered the flower hall.

"The doctor we invited said that the old lady is suffering from heart failure." Uncle Su's face was solemn. "The heart suddenly began to fail. The soup can only nourish her a little, but it can't stop her physical condition from getting worse..."

"Uncle, do you mean that grandma is in a very bad condition?" Jiang Zhan asked.

Uncle Su glanced at the door and nodded slowly: "The doctor said that people with this disease may suddenly stop their heartbeat. Now we can only pray for God's blessing..."

Jiang Yi's eyes suddenly turned red and she wiped her tears with a handkerchief.

Jiang Zhan winked at Jiang Si, wanting her to persuade Jiang Yi, but saw that Jiang Si looked absent-minded.

He had no choice but to persuade her: "Sister, don't cry, grandma will definitely be blessed by heaven——"

The words of persuasion that were about to follow were held back by Jiang Yi's incoherent words.

"My mother was like that, too."

"Sister, what did you say?" Jiang Si suddenly came back to his senses and stared at Jiang Yi.

Jiang Yi didn't look at Jiang Si, but at Uncle Su: "Uncle, do you remember that my mother also died of heart failure..."

Uncle Su nodded slightly.

Jiang Si grabbed Jiang Yi's hand and said, "Sister, do you still remember what happened when our mother died?"

"I was old enough to remember things by then, so I remember some of it."

For a young child, the two most important people in his life are his parents.

Although Jiang Yi was young when Su died, she left an indelible impression on him.

"Could it be possible that heart failure can be passed down from mother to daughter?" Jiang Yi murmured.

Uncle Su frowned and said, "Yier, don't overthink it. You might scare your brother and sister."

Jiang Zhan shouted, "Uncle, we should find out why it has to be passed down from mother to daughter. My eldest sister and fourth sister are weak and can't handle it like me..."

He looked like he had deep hatred that was passed down from mother to son, and Uncle Su Da and Uncle Su Er both twitched their mouths.

This nephew is really simple-minded. Hoping that the disease will be passed down from mother to son doesn't mean he is cursing them to suffer from heart failure as well.

While she was secretly complaining, she was also moved by Jiang Zhan's love for his sisters.

Jiang Yi raised her hand and hit Jiang Zhan, saying angrily, "Second brother, don't talk nonsense."

If my grandmother's disease was really hereditary, she would rather bear it herself than let her brother suffer from it.

"I feel a little uncomfortable and want to rest for a while." Jiang Si said suddenly, holding his forehead.

In the past, if Jiang Si felt uncomfortable, he would at most say it in private, but would never say it in front of elders like Uncle Su.

As a younger person, it would be rude for her to say this, but as the Princess of Yan, no one would object to her saying this.

The convenience brought by the improvement of status is self-evident.

The eldest wife, Youshi, immediately arranged for a maid to take Jiang Si to the guest room to rest.

Jiang Yi followed him out of concern.

"Fourth sister, how do you feel?" Seeing Jiang Si's pale face, Jiang Yi asked hurriedly.

Fourth sister is braver than her and shouldn’t be scared by what she just said.

Jiang Si did not reply to Jiang Yi immediately, but told Ah Man: "Go and guard the door. If anyone comes, speak up immediately."

Jiang Yi looked at Ah Man, then at Jiang Si, and sensed something was wrong.

"Fourth sister, what's wrong?"

Jiang Si bit her lip and clenched her hands so tightly that her knuckles turned slightly white.

"Sister, was my mother's condition really the same as my grandmother's?"

It turned out that the fourth sister wanted to know about her mother.

Jiang Yi nodded slightly: "Yes, at that time, mother was getting weaker day by day. I was very scared and stayed with her all day. One time, I heard the doctor tell my father that mother was suffering from heart failure. The medicine could only prolong her life, but it could not save her life..."

Speaking of this, Jiang Yi's eyes appeared the image of Su's death.

The beautiful woman, like a withered flower, looked at her quietly with a smile, but her eyes were filled with unremovable sorrow, full of reluctance and concern for her young children.

It was the most heartbreaking look she had ever seen, and it reappeared in her dreams for many years, waking her up crying and looking for her mother.

Her mother passed away at such a young age, leaving her, her younger brothers and sisters, and her father behind.

"My mother looks just like my grandmother."

Jiang Si stretched his hand in front of Jiang Yi and asked word by word, "What about the nail on your left middle finger? Are those three blood lines the same?"

She asked, her voice trembling with suppression.

Jiang Yi looked at Jiang Si suspiciously: "Fourth sister, why do you ask this--"

"Big sister, think carefully, before mother died, did the third finger of her left hand also have three blood lines like grandma's?"

Jiang Yi suddenly became nervous. Under her sister's questioning, all her thoughts turned into one word: "Yes!"

Jiang Si was supporting the bed with his hands, his face looking extremely ugly.

"Fourth sister, what happened?" Jiang Yi held Jiang Si's hand as if holding a piece of ice.

There was no expression on Jiang Si's face, but his eyes were like a cold pond, bottomless.

"Mother didn't die of illness!" she said word by word after a long time.

The color on Jiang Yi's face suddenly faded. He stared at Jiang Si and asked in a trembling voice, "Then, how did my mother die?"

Jiang seemed to close his eyes, then open them again, lowered his eyes and stared at his fingers motionlessly.

The young woman's fingers were white and tender like spring onions, and her well-trimmed and rounded nails were a healthy light pink.

"It's poison," she said softly.

To be honest, it's not poison, but a dragon.

There is a kind of insect that can attach itself to the wall of a person's heart and feed on the heart's blood. Over time, the person will become weak and show symptoms of heart failure.

The most obvious sign of being infected by this kind of snake is the appearance of three faint red lines on the nail of the third finger of the left hand.
