Anger flooded the body, and hatred blinded the eyes. After experiencing this continuous stimulation, the psychology professor eventually lost his mind.

Ye Xianguo unconsciously lifted his wife's favorite pointed kitchen knife, clenched it, and walked towards Jiang Acai in the corner step by step.

The rain was pouring outside the house, but at this moment, Ye Xianguo's blood was almost burning.

A bolt of lightning streaked across the sky, illuminating the dark basement. At this moment, Jiang Acai in the corner finally reacted.

After seeing the expressionless Ye Xianguo approaching with a knife, Jiang Acai was suddenly paralyzed on the ground in fright, and urinating, and constantly kneeling and kowtowing.

Compared with anger, what filled Ye Xianguo's heart was still a trace of doubt.

Why, why did the father and son do this? He had obviously promised to cure Jiang Sheng, and he had obviously found a way to treat him. At the beginning, on that rainy night, he was kind enough to take in the father and son.

But why did they torture and kill their wives and children in such a cruel way?

Everything has a cause and effect, just like the butterfly effect, a butterfly that flapps its wings eventually causes a storm.

As mentioned before, porphyria is an extremely rare condition, which is mainly acquired through genetic means, and of course, there is a certain probability that acquired stimuli will be obtained.

However, it is not by chance that Jiang Sheng suffered from porphyria, because Jiang Acai himself is also a porphyria patient, but he has always concealed it well.

Since birth, Jiang Acai has been a mute.

When he was about ten years old, in addition to not being able to speak, he realized that he was different from ordinary people: that is, he had a special urge for blood.

Once, the sister of the neighboring village was bitten by a snake and the wound was broken, and the dark black blood continued to overflow down the gap.

As the blood ran down his throat and into his body, a sense of satisfaction that had never been felt before spread throughout his body, as if the missing part had been replaced.

Because, since he was a child, he knew that he was different from ordinary people, and Jiang Ah knew better how to hide his illness. In addition, he contracted this strange disease because of the stimulation of the day after tomorrow, so it was not as serious as Jiang Sheng behaved.

Whenever he went out to work during the day, Jiang Acai would bring a broken hat and a long coat to prevent the impact of sunlight on his body. And whenever his body has the urge to suck blood, he will run into the mountains alone to catch pheasants and rabbits.

All along, Jiang Acai has been hiding it so well that when he got married, his wife didn't find out. If he could, Jiang Acai hoped that he would be able to hide it for the rest of his life, work at sunrise and rest at sunset every day, and live an ordinary and ordinary life like this.

However, his good wishes were completely shattered with the birth of Jiang Sheng.

This child, like him, has a knack for bloodsqueezing. Moreover, compared to Jiang Acai's illness at that time, it was even more serious.

Because of the backwardness of culture and lack of knowledge, people didn't know that Jiang Sheng was sick, but just helped him treat him like a monster. There are even rumors that the ancestral tomb of the Jiang family did something hurtful to the heavens and reason, so it was retribution, the son born was mute, and the grandson born was a monster.

His parents and fellow villagers refused to recognize him, neighbors and fellow villagers bullied and ridiculed him, and his wife couldn't stand the gossip and finally hanged herself.

The blows of life followed, but in the face of these, Jiang Acai could not do anything except endure it silently. It's like taking a cigarette butt to burn a dumb person, the dumb person can't shout, he can't scream, but he knows it hurts. Every night, this man hid in the quilt and wept bitterly, he also thought about suicide, and thought about dying with Jiang Sheng.

Late one night, he strangled Jiang Sheng's neck with a white cloth, intending to end it. Just as he was about to exert himself, Jiang Sheng suddenly woke up, stared at Jiang Acai with big eyes, and squeezed out two words from his mouth for a long time: Dad, it hurts!

At that moment, Jiang Acai's heart felt like he had been stabbed severely. Although he is a mute, he is also a father, looking at the innocent child in front of him, Jiang Acai still failed to do it in the end.

That night, he made a decision, even if he died of hardship and exhaustion, he would definitely cure himself in his lifetime! When it was just dawn, Jiang A stole all his parents' savings, took Jiang Sheng, and left his hometown to find another way out.

Over the years, their father and son have traveled all over China on their legs, looking for countless famous medical hermits. However, most of the hospitals were helpless about Jiang Sheng's strange illness, and some people even fisted and kicked each other, cursing and driving the father and son out of the hospital.

Half a year ago, when Jiang Acai was passing by a deserted village, he met a certain immortal. That great immortal usually makes a living by helping people exorcise ghosts and eliminate disasters, and uses some small tricks to deceive and deceive. After seeing Jiang Sheng's blood-sucking scene and the money in Jiang Acai's pocket, Daxian made up a ridiculous story from his heart.

Daxian told Jiang Acai that Jiang Sheng was a Yin Yang Heavenly Master in his previous life, because he killed zombie generals and was cursed, and after he was reincarnated, he had to live by sucking human blood for the rest of his life. To cure this strange disease, there is a way, but this method involves heaven and cause and effect, if you tell Jiang Acai like this, I am afraid that my yang longevity will be damaged。。。。。

After hearing that there was a way to treat Jiang Sheng, without the slightest hesitation, Jiang Ah handed over all the money to that great immortal.

Daxian told Jiang Acai that if he wanted to completely unravel the curse of placing his ministers on Jiang Shengsheng, he had to eat the hearts of a pair of boys and girls who were born on a cloudy day. Only by countering yin against yang can it be reconciled and resolved.

At the time of separation, Daxian stretched out his right hand, calculated a hexagram with a lot of concern, and pointed in a direction, telling Jiang Acai that if he followed this direction, he could foresee the pair of boys and girls born on the cloudy day.

Jiang Acai thanked Daxian gratefully, and went all the way in that direction.

He crossed the mountains, crossed the river, and finally, on a stormy night, he hid in Ye Xianguo's mansion in order to avoid the rain, and coincidentally, Ye Xianguo happened to have a pair of children。。。。。

Ye Xianguo wanted to save them wholeheartedly, but Jiang Acai wanted to kill them wholeheartedly. The tragedy has been doomed since then.

Although Jiang Acai can't speak, he is not stupid. He knew that he was weak, and the other party still had guns, if it was a head-on conflict, he would never be the opponent of Ye Xianguo and his wife.

So all along, he has been waiting for an opportunity, staying in obscurity in the basement, receiving treatment from Ye Xianguo, and at the same time hibernating in the dark, waiting for the opportunity to come.

A week ago, when Ye Xianguo worked overtime at the research institute every day and no longer went home, Jiang Ah knew that the opportunity he had been waiting for had finally appeared.

He first slipped into the bedroom while the nanny didn't close the door for the first time, removed the bullets from the double-barreled shotgun, and secretly took the pointed kitchen knife from the kitchen.

Wait until the babysitter traces down the kitchen knife to the basement because of the loss of the kitchen knife.

He stabbed the nanny with a knife, and then rushed up like a hungry tiger and bit her neck directly. Because he has eaten living things since he was a child, he has already cultivated a bite force that is different from ordinary people, so when he re-inhales blood, Jiang Acai is like a new life.

After that, everything was as Ye Xianguo had predicted. Jiang Acai rushed to the second floor, kidnapped the two children, and seriously injured Mrs. Ye with a kitchen knife.

This kind woman didn't believe until she died that this thin man in front of her would do this.

After that, Jiang Acai took Mrs. Ye and the two children into the basement, because the children were still young, they were already trembling with fear, and they had no ability to resist at all.

Looking at Jiang Sheng with an indifferent face on the side, Jiang Acai raised the kitchen knife expressionlessly, slashed the chests of the two of them, and forcibly took out the heart with his hand and distributed it to his son.

Looking at Ye Xianguo, who was approaching, Jiang A knew that he had to die. It's just that before he died, he made a request, hoping that Ye Xianguo could meet him.

And it was this request that dragged me, and many innocent people, into the abyss from which they could never recover.
