"I read in my chemistry textbook that heavy metals can cause poisoning, especially mercury, which can accumulate in the bone marrow after entering the human body. So every time Chen Haobei came to my house for dinner, I would put the prepared mercury into the food he was about to eat."
Liu Yiyi looked into Ye Feng's eyes calmly and spoke in a deep voice, enunciating each word.
She spoke in such a calm tone, as if she was not murdering a person, or even a small animal like a cat or a dog, but rather as if she was talking about how to crush a blade of grass to death.
Jiang Yixue shuddered, and her hands around Liu Yiyi's shoulders were shaking unconsciously.
She couldn't imagine how much pressure a little girl of this age would have to bear when doing these things.
And if it wasn't for the overwhelming hatred, how could Liu Yiyi do such a thing at her age.
"How long did you do this? And what was the dose of mercury each time?"
But unlike Jiang Yixue's trembling, Ye Feng's expression was very calm, and there was even a faint smile at the corner of his mouth.
“It’s been almost two years…”
Although Liu Yiyi didn't understand why Ye Feng laughed, after thinking for a moment, she replied to him: "As for the dosage each time, I haven't calculated it, it's probably around one milligram."
"How many times does Chen Haobei visit your house every year?" Ye Feng's smile deepened as he asked again calmly.
This time Liu Yiyi did not hesitate and answered quickly: "He always goes there once or twice a month, which means 20 to 30 times a year."
"Hahaha… "
Hearing this, Ye Feng immediately threw his head back and laughed, shaking his head continuously as he laughed.
Ye Feng's laughter made Liu Yiyi's pretty face flush red. She widened her eyes and asked, "What are you laughing at? Don't you believe me?"
"Ye Feng..."
Jiang Yixue also frowned and gently touched Ye Feng.
She really couldn't understand what was so funny about Liu Yiyi's words other than the sadness and shock.
But Ye Feng just laughed so hard as if he had heard a big joke.
"It's not that I don't believe you..."
Ye Feng smiled and shook his head, then looked at Liu Yiyi with a playful look, and said lightly: "It's just that I think if you can persist in poisoning for two years without being discovered by Chen Haobei with your method, it's really a miracle."
"I was so careful, he couldn't even notice!"
When Liu Yiyi heard this, a hint of pride appeared on her face.
"careful?"
But after hearing her words, Ye Feng's expression changed from amusement to mockery, and he said lightly: "Do you know that just 0.3 grams of mercury can take the life of an adult! As long as one milligram of mercury vapor is inhaled within five hours, acute mercury poisoning will occur, not to mention swallowing two milligrams of mercury directly!"
"ah… "
Liu Yiyi opened her mouth wide, and the smugness on her face disappeared in an instant.
She only knew that heavy metals like mercury could kill people, but she didn't know that it was so toxic.
Even Jiang Yixue was in disbelief; she had never expected that a tiny amount of mercury could be so toxic.
"And according to what you said, you poisoned Chen Haobei for nearly two years, nearly 20 to 30 times a year, so Chen Haobei must have swallowed five or six grams of mercury every year! With such a dose, let alone a human, even a cow or an elephant would have died long ago! Chen Haobei has lived until now, could it be that he has an indestructible body?"
Ye Feng smiled indifferently, with a hint of amusement in his voice, and said lightly: "So the person who poisoned Chen Haobei was never you. And the poison you gave him was probably discovered and replaced by someone long ago. Otherwise, do you think you can survive until now?"
"If it's not me... then who could it be..."
Liu Yiyi's body was staggering, as if all her strength had been drawn out. But deep in her eyes, in addition to shock, there was also a hint of relief.
Although the hatred between her and Chen Haobei is irreconcilable, no matter how you look at it, the psychological burden that a girl who just graduated from high school has to bear when asked to do something like murder is almost no different from a mountain.
In the past two years, Liu Yiyi had nightmares every night and would wake up from them in shock.
Killing someone was something that she, who could still be called a child, could not afford.
Now Ye Feng's words made her feel that all the burdens in her body were relieved, and the tense feeling finally relaxed.
But soon, Liu Yiyi's eyes showed deep doubts, and she asked anxiously: "If it's not me, then who is it?"
She was the one who poisoned Chen Haobei all along. If her method was ineffective and Chen Haobei had noticed it long ago, then why is Chen Haobei now in the late stage of mercury poisoning
And who was that person who, after she poisoned Chen Haobei, replaced the poison with another one and saved her from the disaster
Could it be...
Hearing Liu Yiyi's words, Jiang Yixiu's heart trembled, and she suddenly thought of something. Then, some pity and emotion appeared in her eyes as she looked at Liu Yiyi, who was shocked and wanted to get an answer.
"You know who this person is better than any of us."
Ye Feng smiled faintly, looked into Liu Yiyi's eyes, and said calmly: "Who else could be exposed to Chen Haobei's food like you, and could notice that you poisoned Chen Haobei, and clean up your immature and stupid behavior except her?!"
"She... is she..."
When Liu Yiyi heard this, her body became stiff as if frozen. Then, tears suddenly rolled down her clear eyes, and she murmured, "It's Mom..."
Liu Yiyi's feelings towards Bai Wu have always been extremely complicated.
She hated Bai Wu. She hated her for not fighting Chen Haobei to the end after her father's death, but for why she depended on him
But she also understood that if it wasn't for the need to take care of herself and if it wasn't for the fear that she would be left alone, how could Bai Wu endure the humiliation and face Chen Haobei's insult.
The reason why she wanted to poison Chen Haobei and kill him was not only to avenge her father, but also because she wanted her mother to no longer have to endure Chen Haobei's humiliation.
But what she never expected was that the mother who seemed to be so tolerant and cowardly in her eyes, actually did so many things for her in secret without her knowledge.
Even if it weren't for her mother, her self-proclaimed clever but actually stupid and clumsy methods would have been discovered by Chen Haobei long ago, and she might have turned into a pile of bones because of these things.
But while she felt ashamed, moved and shocked, her heart was also filled with doubts.
How did the seemingly weak mother manage to poison Chen Haobei to the bone marrow without being discovered
