Ji Feng returned home after a week in the hospital.

His wounds had not yet healed, so he could not go to work. He just came to the files of the Jian family tragedy and sorted out this serial murder case from the beginning.

The Jian family case occurred on August 2, 2014, the Chinese Valentine's Day.

Before that, the murderer had killed three families in succession, namely:

On May 13, 2012, Mother's Day, the mother and son of the Guo family died at home. The mother was 32 years old, the eldest son was 8 years old, and the youngest son was 6 years old.

On September 12, 2011, the Mid-Autumn Festival, the three members of the Cai family died at home. The father was 35 years old, the mother was 34 years old, and the daughter was 10 years old. On

October 26, 2009, the Double Ninth Festival, the grandparents of the Zeng family died at home. The grandfather was 60 years old, the grandmother was 56 years old, and the grandson was 9 years old.

In addition, on August 2, 2014, the Chinese Valentine's Day, the three members of the Jian family, the parents died at home, and the 14-year-old daughter Jian was taken away.

All the families have three people. According to the testimony of the neighbors and relatives, they are all harmonious families. The parents and elders have no bad habits, the children are obedient and sensible, and they have almost no enemies.

Choosing such a family to commit the crime must have a problem with the brain.

But Ji Feng is not very interested in his own mental journey, but more concerned about the clues left at the scene.

However, if there were any clues, the police would not have sealed the case until now.

There were almost no traces left at the scene. The door lock had not been pried open. He must have made a key or tricked the owner into opening the door.

The victims did not suffer much torture. They either died in a coma or were killed with a single blow, without much pain. Finally, the bodies were placed in the same space, a bedroom or a living room. This kind of reunion seemed to be the ritual the murderer wanted.

Fingerprints, footprints, personal belongings... nothing.

The murderer was restrained and quiet, and did not leave many useful clues. The selected families were also scattered all over the country. In the era of poor information, it was difficult for the local police to link the cases together in time.

The joint investigation was after the case in 2012, but he immediately disappeared and did not appear for two years. The clues were cut off when the investigation failed.

Initially, the case of the Jian family was not included because the murderer had never left anyone alive before. But the cleanliness of the scene and the special time eventually allowed the police to lock on the same person.

Jian Jing's safety also became the most pressing topic at the time.

But she seemed to have evaporated from the world and could not be found anywhere. Many people thought she was dead.

No one expected that a few months later, she returned home by herself, weak, with a continuous low fever, extremely bad mental state, and unable to communicate normally.

The psychiatrist believed that she had suffered serious mental abuse and could not cooperate with the investigation and needed proper treatment.

Therefore, Kang Mucheng sent her abroad for treatment and took her back at the end of 2015.

When the police came again, she didn't remember anything, not even the case itself.

Considering her age and special circumstances, the police had to suspend the investigation.

Until today, the case was reopened.

Ji Feng found it very interesting - not only the murder case was interesting, but Jian Jing was even more interesting. Just looking at her performance, who would have thought that she had such a terrible experience?

He couldn't help but recall the scene when he first saw her.

In the hospital, she sat on the bench in a daze, mechanically clutching a bag of glucose in her hand. The nurses' faces were filled with fear and joy of surviving a disaster.

"Fortunately, the patient found it, otherwise..."

"Such a young girl actually has such courage."

"It's amazing." It's

not that he is partial to his sister. When he heard these discussions, the image that came to his mind was a girl like Ji Yunyun, lively, outgoing, and reckless, but when he looked closely, he guessed wrong.

At that time, she was curled up in the bench, dazed and at a loss, with deep confusion in her eyes. She was

weak, helpless and pitiful, like a little white rabbit that had strayed into a wolf's den.

However, he knew that human courage had nothing to do with their appearance. A weak person could be brave and fearless, while a strong person could be as cowardly as a mouse.

She was certainly a brave girl.

That was nothing. Although the disaster of exterminating a family was tragic, kind people would not become cynical because of it. They were still upright and brave, and even more motivated.

But Jian Jing's situation was different.

She was taken away by the murderer for several months, and her mental state was very bad after she came back. It was obvious that she was greatly affected. But according to his observation, Jian Jing's mental state was very normal and she had never shown any abnormality.

Why? What was wrong with her?

At five in the morning, the sleepless Jian Jing went for a morning run in the empty riverside park.

After staying up late, vigorous exercise would be considered suicidal in ten years, but at the age of twenty-one, with a body that is stronger than the average, it is just willful at best.

Besides, she was not just running, and the probability of getting a strengthening card when drawing cards during exercise was higher.

She had saved up a wave of courage points before, so she didn't feel bad when drawing cards now.

[Enhancement Card·Physique (1 point)]

[Skill Card·Pancake (Basic)]

[Enhancement Card·Agility (1 point)]

[Skill Card·Tai Chi Sword (Basic)]

[Enhancement Card·Endurance (1 point)]

[Knowledge Card·Dog Training (Basic)]

Yes, you can tell by looking at the cards. She accidentally ran into a grandfather doing morning exercises, a grandmother walking her dog, and a mobile pancake stand.

She used up three enhancement cards to upgrade the character's data.

Character data (basic)

Constitution: 8 (You are in great shape, not prone to illness, and have strong recovery ability)

Strength: 8 (You can subdue an average adult male)

Agility: 8 (You react quickly and move nimbly, better than most people)

Burst: 8 (The crucial few seconds determine victory or defeat)

Endurance: 7 (Modo Modo~~)

[System: The host's average data is detected to be 7.8, which exceeds the human average of 7.5. The second-level panel can be opened]

Jian Jing: "Isn't the average data 6?"

[System: This is the average value of adult women]

OK.

What is the Level 2 panel?

Character Stats (Level 2)

[Unlocked] Memory: 6 (ability to remember, recognize, and reproduce things you've experienced)

[Unlocked] Flexibility: 6 (flexibility and coordination of various parts of the body)

[Unlocked] Immunity: 6 (prevent pathogens from invading, and eliminate abnormalities in the body in a timely manner)

[Unlocked] Adaptation: 6 (ability to tolerate extreme environments)

[Unlocked] Reproduction: 6 (you know~)

Jian Jing: It's cracked.

After working hard for a year, I finally upgraded my damn stats to a higher level, and now I'm opening a new panel?

Isn't this just a krypton gold scam?

[System: You can use three primary cards to synthesize an unlocked card and unlock the secondary card slot]

Jian Jing: "Where should I add points?"

[System: Three enhanced cards are synthesized into an advanced enhanced card (1 point)]

Jian Jing was confused: "It's too complicated. Can I just draw it with 15 points?"

[System: Yes]

[System: New card pool·Advanced is open]

[Consume 15 points of courage to draw a card (advanced)]

[The card pool includes but is not limited to: skill upgrade cards (primary→advanced), knowledge upgrade cards (primary→advanced), advanced enhanced cards (secondary data), etc.]

[System: Please note that the host has to start from the ground up. The advanced card pool is only used to increase the level. Any knowledge or skills must be obtained from the primary level. Please don't aim too high]

"Got it." What a worrying system.

Jian Jing began to worry.

She had planned well, and before officially encountering the scarred man, she would increase her physical data a little bit so that she would have more coping capabilities.

It didn't matter if there were extra cards, she could just synthesize upgrade cards and improve other skills.

Now there was an extra second-level enhancement, should she use it?

She struggled for a few seconds, and finally, just like a new gameplay appeared in the game, she couldn't help but want to try it.

Among the several enhancement options, flexibility and immunity are more practical, the former can complete some delicate work, and the latter can be immune to the intake of some poisons.

It's not impossible to turn on both, but the courage value is not enough, and unlocking and upgrading both cost money!

So black-hearted.

After weighing it, Jian Jing decided to choose "immunity", which is the protection she needs all the time.

The three primary cards just now were combined into [Unlocked Card], and the Immunity Card slot was opened.

[Unlocked] Immunity: 6 (Your immune system is neither high nor low, and it works normally)

"Draw 1 advanced card."

[Card drawing in progress]

[Advanced card drawing completed]

[Name: Advanced Enhancement Card·Immunity (1 point)]

[Description: Improves immunity and slightly enhances resistance to drugs/poisons]

[Note: Humans are far more fragile than you think~]

[Unlocked] Immunity: 7 (You have a slight resistance to strange things)

Well done!

She went home satisfied, took a bath and went to bed.

I woke up at noon and was woken up by a phone call: "Who is it?"

"No way, you are not awake yet?" Ji Feng said in surprise, "Teacher Jian, your sleep and rest schedule is not very healthy."

Jian Jing cleared her throat: "What do you want me for?"

"Are you free? I want to discuss something with you." Ji Feng replied.

She: "Go ahead."

"I just flipped through the file of the scarred man. The earliest record is in 2009, but this case has been handled very skillfully. I think it should not be his first crime." Ji Feng analyzed.

Jian Jing said "hmm", and asked curiously: "So, you want to find the first case?"

"No, I want to re-investigate the case in 2009." He said, "Since the previous case is not included, there must be something missing. This crime must have part of his first attempt."

"How to check?"

The rustling sound of turning pages came from the other end of the phone. Ji Feng said: "Let me tell you about this case first. The victim's family is surnamed Zeng, with a total of three people. In 2007, the son and daughter-in-law died unexpectedly, leaving only a little grandson, who was raised by grandpa and grandmother.

"According to relatives, the elderly couple both have pensions, and the children are young, so they live a good life. Grandpa likes to play chess, and often goes to the community to play chess with other elderly people, which can take a whole day. Grandma is in good health and very hardworking, and the house is very clean.

"Neighbors think that the Zeng couple are kind to others, rarely quarrel with others, and have no enemies. But some acquaintances say that the old lady has a problem and is easily deceived. She has bought several insurance policies. People advised her not to do so, but she insisted on leaving some protection for her grandson."

Jian Jing was very perceptive: "Is there something wrong with the insurance seller?"

"The neighbors said that a few months before the incident, an insurance salesman went to Zeng's house several times." Ji Feng said, "You have to know that there were no signs of violent intrusion at the crime scene. The only people who could make the old man open the door, apart from neighbors and relatives, should be these salesmen."

He paused and explained the plan: "The resident living opposite Zeng's house has met this insurance agent. I want to visit him again to see if I can get any useful clues."

Without hesitation, Jian Jing said, "I'll go too."

"Very good." Ji Feng smiled, "The road is a bit far, otherwise, shall we leave today?"
