The sky was already dark, and puffs of smoke rose from the firewood pile.

"Geng Zhi, what the hell is going on, how did Gu Yan become like that?" Xue Lingling still couldn't believe what she had just seen, if she hadn't seen it with her own eyes, she wouldn't have believed that Gu Yan had done such a thing.

At this time, Gu Yan quietly rested his head on Xue Lingling's lap, and Xue Lingling wiped the blood off his face. showed a handsome face that fascinated thousands of women, quietly like a child.

The monkey cautiously tested Gu Yan with his eyes closed with a stick, and the monkey who had experienced that scene was afraid of this man with red eyes.

Geng Zhi bandaged the wound on his hand and glanced at the sleeping Gu Yan. For the scene just now, Geng Zhi was also very shocked in his heart. You must know that it is impossible for Gu Yan to be sober like that, but Xue Lingling is just two short sentences, which easily made Gu Yan stop killing, and even made Gu Yan have a sober consciousness.

Geng Zhi's non-reply made Xue Lingling even more anxious, she desperately wanted to know why Gu Yan had become like that, and why would he raise a knife to them, they were brothers.

"The people of the Gu family have had such a disease since before, when the external stimulation point reaches a certain level, they will lose their minds, just like you just saw, the six relatives do not recognize. What Geng Zhi didn't expect was that Xue Lingling could wake up Gu Yan.

"Then why don't grandpa and dad have them? neither do the people in the second room of the Gu family?" Xue Lingling didn't understand, looking for Geng Zhi to say this, the same person from the Gu family, why only Gu Yan had such an illness.

"Do you know what porphyria is?"

Geng Zhi brought up a word that Xue Lingling had never heard before, and Xue Lingling shook his head. Geng Zhi looked at the sleepy Gu Yan and said, "Porphyria is a very rare disease, and there is almost no possibility of curing it for people who have this disease. You can only rely on medicine to prolong your life. ”

Geng Zhi paused, and there was a way, "People with porphyria are very afraid of bright light, and even seeing blood will cause manic factors in the body, so as to lose their minds. He even went on a killing spree, knowing that all living creatures were dead. ”

"So Gu Yan has porphyria?" Gu Yan just now really lost his mind, which is very in line with Geng Zhi's porphyria.

Geng Zhi nodded, and shook his head again. This nodded and shook his head, but Xue Lingling was stunned, whether Gu Yan was porphyria or not?

"To be precise, Gu Yan has the gene for porphyria, I heard Uncle Gu say it. Two hundred years ago, there was a head of the family who suffered from porphyria, and the children of the later generations of the family, although there were no obvious porphyrin symptoms, more or less carried the porphyria gene in their bodies. ”

This is why the Gu family in the early stage will go from prosperity to decline, and it is precisely because of the existence of porphyria that it led to the decline of the Gu family later. Since the death of the head of the family, no one has been found to have the gene for porphyria.

More than two hundred years passed peacefully, until that dark night twenty years ago, Gu Yan broke out. There were countless deaths and injuries that night, and the Gu family also knew that Gu Yan had a rare recessive gene for porphyria. What happened that night was silenced by Gu Wei, and no one except the Gu family knew what happened that day. This is why everyone in the Gu family is afraid of Gu Yan.

"Then Gu Yan will also become such a monster?" Xue Lingling's hand paused, and his pupils dilated slightly.

"No, Zhong Leixi showed him that the porphyria factor in his body is not very strong. As long as it is not stimulated by uncontrollable irritation, it will not have seizures. At least Gu Yan has no symptoms of porphyria now. As for whether it is dangerous, Geng Zhi does not know, and Zhong Leixi cannot give an exact diagnosis.

"You mean to say that Gu Yan won't become such a monster, but whether there is a possibility of an attack is unknown?" Xue Lingling seemed to understand something.

"Gu Yan had a seizure from twenty years ago, and today is the second time. "Counting it up, Gu Yan is the second time to have an attack.

"Then this kind of gene, will it be ...... in the future" Xue Lingling didn't finish her words, and Geng Zhi also knew what she wanted to say.

"It may or may not. Geng Zhi did not dare to guarantee whether porphyria would be inherited, Geng Zhi did not know.

Xue Lingling lowered his head, not knowing what he was thinking. Geng Zhi also understood what she was worried about, this disease would be passed on to the next generation.

"Gu family, who else has such a disease?" Is Gu Yan the only one?

"There is another one, but it is not very obvious, and it is not as serious as Gu Yan's. Geng Zhi picked up the fire with a stick to make the fire more vigorous.

Xue Lingling raised his head, "Who is it?"

"Gu Ming. ”

"What, how could it be Gu Ming?" Xue Lingling couldn't believe it, Gu Ming was just a 12-year-old child. How could there be such a terrible disease?!

"Since Gu Yan's illness, the Gu family has come to a major physical examination, and at that time, the Gu family only found two people with porphyria, one is Gu Yan who has already had a seizure, and the other is the newborn Gu Ming. ”

Gu Ming has a porphyria gene, except for Zhong Leixi and Old Man Gu, only Yang Hui knows. None of the others found out that Gu Ming was also a potential patient with porphyria, perhaps because there were porphyria factors in the body, Gu Ming naturally liked to be close to Gu Yan.

"Do you regret it?" Geng Zhi saw Xue Lingling's hesitation, and knew that who knew that the other half of the people had this terrible disease, it was impossible not to be afraid.

Xue Lingling didn't answer, what she couldn't deny was that she was indeed afraid of Gu Yan, and even more afraid of Gu Yan's life after this illness.

"I regret it now, it's too late. Geng Zhi stirred up the fire, hoping that Xue Lingling would think it through.

The squeaky flames were just like Xue Lingling's mood now, and he didn't know how to calm down. Do you regret it? Xue Lingling's heart was like an overturned spice bottle, with mixed tastes.

Xue Lingling didn't answer, Geng Zhi knew that it would take time for Xue Lingling to accept this matter. Didn't bother, just stayed quietly.

"Squeak. The monkey sensed Xue Lingling's sensitive emotions, and obediently stood aside without disturbing Xue Lingling.

The morning star rose, and the first rays of sunlight pierced the sky, waking up the sleeping Gu Yan and Jiang Lan. Gu Yan had regained his senses, and he had no memory of what happened last night, as if he didn't know what he had done.

Gu Yan's 'amnesia' gave Xue Lingling a buffer time, which made her relieved and avoided embarrassment with Gu Yan, only Geng Zhi and Monkey still knew her helplessness and hesitation last night.
