Yunzhou, special dispatch office, in the evening.

"Sister Miao," Zeng Ke reported to Miao Yinghui, "I checked the case records in the archives and found no similar cases!"

"Oh?" Miao Ying asked with her chin pinched her chin, "Have you found all the major cities?"

"It was electronically screened," Zeng Ke explained, "not just a few major cities, but all the outstanding cases across the country were investigated throughout the 1990s!"

"The case has not been closed," Choi Lizhu reminded, "Can the case be settled, such as catching the wrong murderer?"

"Well, if you want to investigate the case that has been solved, it will be difficult to investigate!" Zeng Ke said, "In that era, cases that have not been connected to the Internet and have been closed and have no objections will generally not be entered into the electronic database. We can only go to various local police stations to investigate..."

"Oh, then okay..." Miao Ying said, "Maybe, the left-eared murderer will have gone to our country?"

"Sister Miao, where did you get the information?" Cui Lizhu asked curiously, "Why can't I see the connection between the left ear case and the red bathtub case?"

"No, there must be some connection!" Miao Ying stood in front of the case whiteboard and pointed to a place on the whiteboard and said, "We ignored this most important clue from the very beginning!

"If you want to thoroughly find out this case, the most important thing is the white candle and charcoal powder left on the scene!

"We have to figure out why the murderer did this!"

"I don't know anything else, but according to what we know," Cui Lizhu also stared at the whiteboard and said, "The serial murder case that happened in Zhang Fengyi's family must be related to some evil secret technique, and this secret technique is practiced by Zhang Shixiong's grandfather and Zhang Fengyi..."

"Sweat..." Zeng Ke grinned, "The word cultivation has come out, you really have it, Xiao Cui!"

"So," said Miao Ying, "Next, we need to focus on investigating what they believe in!

"And, are they the secret technique they believe in, and the secret technique that Peter brought from Africa, the one they believe in?"

"Sister Miao," Cui Lizhu said, "I have sent someone to contact Zhang Fengyi's colleagues back then. According to what they said, Zhang Fengyi is likely to contact Peter!

“But, so far, no one can prove that the two of them do know each other…

"I'm considering whether we should investigate the opposite," Choi Lizhu said. "Let's find a few people who know Peter and ask them if they know the relationship between Peter and Zhang Fengyi!"

"Well..." Miao Yingyan said, "I think so too. When the case reaches this stage, we have to take out the Peter case from that year and investigate it carefully!

"Xiao Cui," Miao Ying ordered, "In addition to these, you can check again, Zhang Fengyi's father Zhang Tingshan to see if this person knows Peter?

"The information shows that Zhang Tingshan has worked as a seafarer and even speaks English, so he is also likely to know Peter!"

"I understand!" Cui Lizhu took the order, "Don't worry, I will find out the relationship between these people!"

"Captain Shao," Miao Ying turned to Captain Shao and said, "You send someone to investigate Zhang Tingshan, Zhang Fengyi and the secret technique that Peter believes in, see if anyone knows?"

"Yes!" Captain Shao nodded and agreed, and expressed his own ideas. "I think Zhang Shixiong's parents are the best breakthrough. If we can find the person who believed in secret art with Zhang Tingshan back then, we should know what that is!"

While speaking, Wu Xiumin entered the office and reported to Miao Yinghui: "Zhang Shixiong's father no longer resisted and has already told everything!

"What Zhang Shixiong's mother said is all facts. He wanted to say it early in the morning, but he was afraid that after saying it, it would tarnish the reputation of his father and sister, so he chose to hide it..."

"Then..." Miao Ying asked hurriedly, "Did he mention what Zhang Tingshan and Zhang Fengyi believe in?"

"It was mentioned," said Wu Xiumin, "He said that he didn't understand at the time. It would be fine if his father had no education, but why did even his sister, who had a high degree, believe in that kind of thing...

"He said that the secret technique seems to be very technical, it is completely feudal superstitious, but his father and sister firmly believe it...

"However, Zhang's father is more honest. Although he has complaints and worries, he has never stopped him...

"It is precisely because of this that he knows little about that secret technique, and, most unfortunately, after his father passed away, he threw away all the things related to the secret technique..."

"Tsk tsk...it's a pity..." Cui Lizhu expressed regret.

"Then... did you mention white candles and charcoal powder?" Miao Ying asked again.

"Yes, Zhang Shixiong's father once saw Zhang Tingshan worshiping the gods, 7 candles, yellow paper, and a fire circle surrounded by charcoal...

"He said that the scene was particularly evil and even a little scary, and what he was most worried about at the time was whether charcoal would cause a fire..."

"I'll go..." Zeng Ke suddenly said, "Why does it sound a bit like Zhuge Liang's seven-star life-extending lamp?"

"Don't let it go," Choi Lizhu widened her eyes, "Is it so mysterious?"

"No matter whether it is," Zeng Ke said, "Anyway, what we can know is that the life-extending lamp does not work. Didn't Zhang Tingshan and Zhang Fengyi die in the end?"

"I guess, this is probably the case!" Wu Xiumin guessed, "The father and daughter believed in this secret technique. Originally, this secret technique was just an ordinary sacrifice!

"But, after Zhang Fengyi got a terminal illness, their thoughts changed, and they thought of living people celebrating sacrifices..."

"Hey? Wait a minute," Cui Lizhu remembered something and asked hurriedly, "Where is Zhang Shixiong's grandmother? Is his grandmother still alive? Does his grandmother know?"

"Zhang Shixiong's grandmother passed away very early," Miao Ying said. "Zhang Fengyi died of lung disease when she was still very young."

"Oh..." Choi Lizhu said smacked her lips, "Since that's the case, we can only make a long-term plan!"

"What's even worse," said Wu Xiumin, "Zhang Shixiong's father said that except Zhang Tingshan and Zhang Fengyi, he had never seen anyone who believed in that kind of thing!

"He didn't know who Zhang Tingshan and his daughter learned from, nor who else believed in secret techniques with them. He only knew that every weekend, Zhang Tingshan would go to a place called Sijiao Pavilion!

"I guess I must have learned it from there!"

"Square corner pavilion?" Cui Lizhu hurriedly looked at Captain Shao, "What is this place?"

"Oh..." Captain Shao replied, "Sijiao Pavilion is a synonym, specifically referring to the area of ​​Sijiao Pavilion, which is an old residential area. It was demolished and renovated a long time ago, and now it is a botanical garden...

"However," he said to Miao Ying, "Team Leader Miao, leave this matter to me! I will send someone to ask the old people who have moved out of the Sijiao Pavilion to see if they know the origin of this evil secret technique..."
