The lights were on in the interrogation room, but despite being bright, they made people feel uneasy and uneasy.

There was nothing on the clean table. Li Yuebai and Ye Qing sat on one side, and Liang Jing sat opposite them.

"Sister Liang, I'm just taking notes. Don't be nervous." Li Yuebai comforted her, "What we need to figure out next is why Weng Zichen suddenly...became like that."

"I don't know." Liang Jing blew her nose with a tissue, her eyes still red: "I have no idea."

"Then you just need to tell me about your experience today." Li Yuebai didn't intend to put too much pressure on her: "Start from when you were alone in the laboratory."

"Okay." Liang Jing nodded reluctantly. "In the past few days, I haven't been home because I'm preparing for a divorce. I've been living in the dormitory at the institute, and I haven't seen Weng Zichen for a few days."

"Um."

"After waking up in the morning, I had breakfast in the cafeteria and went to the laboratory alone to extract the neurotoxins from snake venom. Everything was normal. It was almost noon when Weng Zichen arrived."

"How is he?"

"At first, he was just like before, wearing a linen suit and carrying a bag with some divorce documents in it. He started arguing with me right away, all kinds of arguments." Liang Jing held her forehead in pain and recalled: "I said this is a laboratory, if you want to argue, go outside, but he didn't care, and in a rage, he picked up a chair and smashed the glass cabinet."

"Is it the glass case with the snake in it?"

"Yes, there are poisonous snakes inside." Liang Jing choked up again: "I originally planned to apply to the higher authorities to replace it with bulletproof glass, but unfortunately the funds have not been approved. In fact, this kind of ordinary glass will be fine as long as it is not hit hard, but..."

The chair was made of heavy stainless steel. When a grown man picked it up and hit the glass with the sharp corner, it naturally shattered into pieces.

"Soon, poisonous snakes crawled out, and he stepped on one in a panic, and that one immediately bit his ankle... It was a very venomous viper." Liang Jing's hands trembled slightly: "He immediately fainted and fell to the ground unconscious. Although I hated him, I couldn't just stand by and watch him die, so I immediately planned to help him. Unexpectedly, before I walked to his side, he suddenly woke up and stood up."

"How long does it take from fainting to waking up?"

"Less than thirty seconds."

The speed at which a dormant vampire possesses a human is very fast; thirty seconds is enough.

"After he woke up, I was shocked as soon as he opened his eyes. I almost cried out in fear. His eyes were no longer human eyes. They were like those of a snake... with vertical pupils! Scales appeared on his skin. I still can't figure out why a snake bite would turn him into this." Liang Jing was terrified and confused: "I am an expert in this area. I have seen countless cases of death caused by venomous snakes, but none of them would cause people to become like this..."

Liang Jing doesn't know about vampires yet, so Li Yuebai plans to wait until she calms down and then slowly explain everything to her. After all, her brother's death and her husband's mutation are both related to vampires, and she has the right to know the truth.

It's just... isn't it just too much of a coincidence that both of these things happened to her?

"Is there any surveillance in the laboratory?" Li Yuebai asked.

According to Liang Jing's description, the dormant vampire took advantage of the moment when Weng Zichen was poisoned and passed out and sneaked in.

But how could it be such a coincidence? How could there be such a dormant organism in the laboratory of the Institute of Biology?

"There was surveillance." Liang Jing replied: "But I didn't see clearly why he became like this. Could the surveillance camera have captured it... The pixels of the surveillance camera are not very high..."

Ye Qing pulled out the surveillance video.

At first, there was no discrepancy with Liang Jing's description. The screen showed Liang Jing doing the experiment alone. At 11:20 in the morning, Weng Zichen kicked open the half-open security door and broke in.

"Wait, something's wrong here." Li Yuebai made a gesture and Ye Qing immediately paused the video.

"Sister Liang, why didn't you lock the door? This doesn't make sense." Li Yuebai was full of doubts and said, "The biological laboratory is originally a research center. No outsiders are allowed to enter. And they are extracting neurotoxins from snake venom, which is quite dangerous. Even in normal times, the door should be locked before conducting experiments. What's more, you have recently encountered an accident and feel very insecure, so you should lock the door even more."

"I..." Liang Jing's face turned pale: "I don't know, I don't know why I didn't lock the door."

Ye Qing retrieved earlier surveillance camera records, which showed that Liang Jing had always been very careful. She would always carefully check the safety conditions in the laboratory before locking the door, and would also check the safety conditions outside before leaving.

But a few days ago, she became less careful and often left the door wide open.

"Let's skip this question and continue reading." Li Yuebai clicked the play button again.

There is no suspense in the following plot. Weng Zichen yelled at Liang Jing angrily, and Liang Jing also retorted calmly. The two refused to give in. After a while, Weng Zichen could not control himself. He picked up a chair and began to smash the table, computer, glassware and glass cabinet frantically... until he was bitten on the ankle by a viper and fainted on the ground.

Next, Ye Qing slowed down the playback speed.

The expected object appeared - a black shadow floated out from the pen holder on the table. Without circling in the air, it went straight into Weng Zichen's head.

"Hey? What is this?" Liang Jing was startled and very surprised: "I didn't see this thing at the time, why was it captured by the camera?"

"Some things cannot be seen by the naked eye and can only be captured by the camera." Ye Qing replied briefly: "I will explain it to you later."

"That's it, the dormant Lilith." Li Yuebai tapped the screen: "It came out of the pen holder."

The pen holder was yellowish-brown in color, bulky and crude in shape, and looked like an ancient pottery product with no patterns on it.

Judging from past surveillance videos, this pen holder only appeared in Liang Jing's laboratory a week ago.

Soon, the evidence department brought it over.

"Where did this pen holder come from?" Li Yuebai put on plastic gloves, took the pen holder in his hand and examined it carefully.

"It was delivered to me by express a week ago." Liang Jing's voice trembled. "I usually fill in my work address when I shop online, so I often receive express deliveries in the delivery room. After I opened it this time, I saw that it was something I didn't buy, but I didn't think it was strange. After all, my classmates and friends all know my address and occasionally send me things. I just opened it and put it in the laboratory."

It is called a pen holder, but it should actually be called a bottle. It is cylindrical, and the bottom was originally conical with a downward pointed corner. It could only stand upright in the sand. It may have been modified and an iron bracket was installed on it so that it can be placed properly on the table. The wall of the bottle is very thick, and the overall weight is not light.

"It looks like a cultural relic. It must be quite old." Li Yuebai knocked on the wall of the bottle, making a dull sound.

He had read some introductions to ancient Western artifacts in textbooks before, among which the Phoenician bottles were very famous. The Phoenicians were a nation good at sailing and flourished before the Common Era. The pottery bottles they made were found all over Europe, Asia and Africa. Judging from the age, this bottle could only be earlier than the 16th century, and it was certainly possible that vampires in the early 16th century could hide in it.

Ye Qing sent the pen holder bottle for a X-ray examination, and it indeed showed that there was a cavity in the conical part of the bottom of the bottle!

It is 100% certain that Lilith came out from here.

But why did Lilith choose Liang Jing and his wife?

Could it be that, like Xu Lili's case, it was just a coincidence? Xu Lili had never offended anyone, nor was she a favorite target for vampires to possess. She was just too unlucky and bought a piece of castle stone online, which led to the disaster.

But Liang Jing is different. Liang Jing's brother Liang Tian was killed not long ago, and now the vampire snake demon Lilith has come. Two disasters befell her alone purely because of coincidence. What is the probability of this?

"No... I guess it's not a coincidence." Li Yuebai frowned: "Sister Liang, please forgive me for asking, what did you do after Liang Tian passed away?"

"What did I do?" Liang Jing's expression immediately changed from sadness and fear to anger when she heard Liang Tian's question. She clenched her hands that were originally placed flat on the table, and her voice became cold: "Of course I cooperated with the police investigation!"

"No, you have endured more pressure than this." Li Yuebai sighed: "According to your personality, you will never allow your brother to die in obscurity, so you must be investigating this case secretly on your own."

"So what?" Liang Jing's eyes widened suddenly: "He is my biological brother, why can't I do something?"

"We can also help with Liang Tian's matter." Li Yuebai said in a low voice.

Liang Jing looked at Li Yuebai steadily, as if judging whether he was worthy of trust.

She knew very well that Gu Xisha and Ye Qingdu had a good relationship with Liang Tian, ​​and Gao Chengyu's case was also directly related to Gu Xisha. Moreover, it was the man in front of her who saved her today...

If you can't trust these two, then there is no third person in this world that you can trust.

Liang Jing sighed: "Well, I am secretly investigating the cause of Liang Tian's death and Gao Chengyu's matter."

"What's going on?"

"I came to a very absurd conclusion." Liang Jing smiled bitterly and shook his head: "From all the signs, it seems that Gao Chengyu came back to life and killed Liang Tian, ​​but how is this possible?"

She was already very close to the truth, and Li Yuebai's heart sank.

"That's it." Li Yuebai said softly, "The reason why the pen holder bottle was sent here is here."

"Could it be..."

"Because your secret investigation was discovered by Gao Chengyu, but he couldn't show up in public." Li Yuebai paused, "So he sent someone to give you the pen holder bottle, trying to use that thing to control you, or even kill you."
