The lethal dose exceeds 5 milligrams, with a mortality rate of over 95%!
Moreover, even if a poisoned person miraculously survives, they will be left with severe sequelae.
Patients with sequelae will suffer from symptoms such as fear of water, light, and wind, living in constant agony.
Of course, the 95% mortality rate mentioned here is based on the system's analysis of Earth's medical technology.
The system's capabilities far surpass Earth's by more than ten thousand years.
Within the system's mall, there are medicines that can completely neutralize the Mu Lü Sha toxin.
Furthermore, Liu Kai Xuan has already purchased the antidote from the mall.
As long as the antidote is administered to Zhao Tian Hai within three days, he will be fine.
However, Zhao Da Jun's behavior just now made Liu Kai Xuan extremely anxious.
Zhao Da Jun actually suspected that Liu Kai Xuan had poisoned Zhao Tian Hai.
The problem that even hospital doctors couldn't solve, Liu Kai Xuan easily resolved with a bottle of medicine.
Isn't that equivalent to confirming... that Liu Kai Xuan was the one who administered the poison?
If it wasn't you who poisoned him, how could you possibly have the antidote?
Therefore, Liu Kai Xuan absolutely could not directly administer the antidote to Zhao Tian Hai.
He needed to find a reasonable way to secretly give Zhao Tian Hai the antidote, doing good deeds without seeking recognition.
Why would he do this?
Needless to say, it was all for Zhao Fei Yan!
Given Zhao Da Jun's disgusting demeanor, if it weren't for Zhao Fei Yan, Liu Kai Xuan would have already lashed out.
Damn it, I'm poisoned too!
Even if I were to go on a spree of wanton slaughter, would I poison myself?
Only a narrow-minded, pig-brained individual like Zhao Da Jun would suspect Liu Kai Xuan.
Anyone with a modicum of intelligence wouldn't spout such nonsensical words.
Zhao Tian Hai's ward.
Upon her arrival, Zhao Fei Yan immediately asked, "Mom, what's Dad's current condition?"
Zhao Da Jun said irritably, "Zhao Fei Yan, I thought you had completely forgotten about our Dad, hmph!"
"Do you realize he's suffering from a severe poisoning and is in critical condition?"
Zhao Fei Yan said in a deep voice, "Brother, what are you saying?"
"My man is also poisoned!"
"And you know, Kai Xuan is also poisoned!"
"As a married woman, what do you expect me to do?"
"Leave Kai Xuan alone in the ward and neglect him?"
Zhao Da Jun said sternly, "Is that what you call being poisoned, Liu Kai Xuan?"
"At most, he just ate something that upset his stomach. He doesn't even need to be hospitalized. You're making a mountain out of a molehill!"
"Alright Da Jun, just say a few less words!"
At this critical moment, Jiang Ai Ying spoke up, "Fei Yan is right!"
"A married woman should indeed put her husband first!"
"Fei Yan... think carefully, who is the biggest suspect in this poisoning incident?"
Zhao Fei Yan said in a deep voice, "Kai Xuan has already told the police comrades!"
"Currently, the person with the greatest animosity towards us in the courtyard is the Jia family!"
"Bong Geng has been imprisoned twice, both for stealing from our family!"
"Qin Huai Ru has always held a grudge about this and wants revenge!"
"If someone intentionally poisoned us, it's highly likely to be Qin Huai Ru!"
"This beast, truly has no humanity!" Jiang Ai Ying said, grinding her teeth in anger.
Zhao Fei Yan then pressed, "Mom, what's Dad's current condition?"
"He was being resuscitated yesterday, why hasn't he woken up yet?"
"Alas..."
Jiang Ai Ying couldn't help but sigh and say helplessly, "The doctor said your dad has a very slim chance of survival!"
"What?"
Zhao Fei Yan's face instantly changed color, "Is it really that serious?"
"Kai Xuan was poisoned with the same substance, why do his symptoms seem so mild?"
"You'll have to ask Liu Kai Xuan himself about that!"
Zhao Da Jun said irritably, "Both of us are poisoned!"
"Our Dad is about to die, and Liu Kai Xuan seems completely fine?"
"Could it be..." Suddenly Zhao Fei Yan recalled something.
But the words caught in her throat, and she ultimately couldn't utter them.
"Could it be what, Fei Yan, have you remembered something?" Jiang Ai Ying asked as if grasping at a last straw.
Under Jiang Ai Ying's urging, Zhao Fei Yan reluctantly replied, "It's nothing, I just heard the doctor say!"
"Kai Xuan's physical condition is much better than my dad's physical condition!"
"It's precisely because his physique is so robust that his reaction to poisoning wasn't that severe!"
"Alas, isn't that the same as saying nothing?"
"Your dad is of that age, how can his physique be compared to a young man like Liu Kai Xuan!"
Actually, Zhao Fei Yan was thinking of the cultivation pills Liu Kai Xuan had given her back then.
Liu Kai Xuan called them "Qiang Ti Wan" (Body Strengthening Pills).
Liu Kai Xuan and Zhao Fei Yan both had very good physiques because they had taken these pills.
Zhao Fei Yan thought that if Liu Kai Xuan could give Zhao Tian Hai a cultivation pill,
Then Zhao Tian Hai's physique would also improve, and perhaps he could withstand the fatal poison.
However, Zhao Fei Yan would have to discuss this matter with Liu Kai Xuan.
If she mentioned it to Jiang Ai Ying and the others, they would immediately think she was crazy.
With that in mind, Zhao Fei Yan quickly left Zhao Tian Hai's ward to find Liu Kai Xuan.
Her idea actually startled Liu Kai Xuan.
"Fei Yan, please don't joke with me!"
"While Qiang Ti Wan can indeed improve physical fitness, its medicinal properties are potent and require digestion and absorption to take effect!"
"Your father is currently in a coma and his physical condition is unable to digest and absorb the properties of Qiang Ti Wan!"
"Giving him Qiang Ti Wan now would actually be harming his life!"
"But..."
Zhao Fei Yan suddenly started to sob, "The doctor said that if my dad doesn't wake up within three days, he's basically beyond saving!"
"The current situation is not optimistic at all!"
"I want to do something for him, I can't just..."
Liu Kai Xuan said in a deep voice, "How about this, Fei Yan, let me go and diagnose your father's condition!"
"Ah, you go..."
Zhao Fei Yan couldn't help but frown, "Kai Xuan, do you know medicine? I never knew!"
"When I was young, I learned some basic medical skills from a barefoot doctor in the village!"
"Given your father's severe condition now, I don't know if I can cure him!"
"But no matter what, I have to contribute my part!"
