On another weekend night, Fu Liangtao arrived at the front hall through a round arch, only to see a spiral staircase on the left and right sides of the front hall. Fu Liangtao then slowly walked up the semi-circular spiral staircase, and there was no one along the road, listening to the singing of the choir from the hall on the second floor above, Fu Liangtao knew that the etiquette had begun.

Fu Liangtao has never liked to be late, but this time, he deliberately arrived late.

After ascending to the second floor, Fu Liangtao passed by the Sheng. Seeing the bookshelves on both sides of the wooden door with songbooks and etiquette books, Fu Liangtao hesitated slightly, but still didn't take it. Fu Liangtao gently pushed open the elegant wooden door with a small window of light and entered the open and bright hall.

After passing through the wooden door, Fu Liangtao felt that the choir singing echoing in the air became brighter and brighter. The benches in front of them were divided into four rows, and the people who were participating in the ceremony stood between the rows of benches and sang in harmony with the choir.

The sound of Xu Jingjia singing also came from the headphones. Xu Jingjia sang loudly, and from her voice, Fu Liangtao could hear concentration and seriousness.

After the previous two weeks of follow-up investigation, Fu Liangtao has roughly grasped Xu Jingjia's life pattern, and also understands that the follow-up investigation seems to have little effect on understanding Xu Jingjia. Therefore, Fu Liangtao thought of another method.

Fu Liangtao walked down the aisle to the right of the bench in the direction where the choir was located, but not to hear the choir's singing. It's because the place where Xu Jingjia is sitting is near the choir.

Fu Liangtao chose a position where people were sitting in front and back, this position was some distance from Xu Jingjia, but Xu Jingjia could be clearly observed. Fu Liangtao thought that Xu Jingjia's voice was already very loud, but after Fu Liangtao stood still, he found that the voice of the man standing behind Xu Jingjia seemed to be much louder than Xu Jingjia's singing.

Even though Fu Liangtao was standing at a distance from the man, he could still hear his singing voice clearly.

In a short time, when the song was finished, the low gong sounded, everyone fell silent, and the solemnity in the synagogue rose to another level. After the priest on the altar prayed, everyone sat down, and Fu Liangtao himself sat down with the crowd.

Without the cover of the crowd, Fu Liangtao saw Xu Jingjia sitting alone with a ponytail, and there was no one next to him except Xiao Si, and there was also a distance between Xu Jingjia's position and Xiao Si. According to their established plan, Xiao Si was originally asked to sit next to Xu Jingjia, but at this time, the two sat at both ends of the row of stools.

Xiao Si was also a member of the Action 2D team, and has been seconded to the Action 1D team since early March to follow up on the investigation of the London Gold Investment Fraud. This time, Superintendent Xu agreed to temporarily transfer Xiao Si back for three hours on Wednesday and Saturday nights to assist in the investigation of Li Bingde's case.

Xu Jingjia lowered her eyes most of the time when she listened to the lecture, occasionally looking up at the stained glass window in the middle of the back of the altar. In the subsequent rituals, Xu Jingjia seems to be familiar with the procedure, whether kneeling, standing or sitting, with the other believers, without a trace of abruptness.

Fu Liangtao is an atheist, and he does not believe in ghosts and gods. Yes, when Fu Liangtao looked at Xu Jingjia with a respectful or pious expression, he suddenly wanted to know what Xu Jingjia was thinking in his heart during this period of etiquette.

Thinking of Xu Jingjia's motive for participating in the party, Fu Liangtao couldn't help but wonder if Xu Jingjia was sincere, or was he just pretending to show someone in this hall?

If Xu Jingjia is just pretending, then who is she pretending to be?

Thinking of this, Fu Liangtao secretly paid attention to the people in the hall, wanting to know who Xu Jingjia's target would be.

"Hello, do you recognize me?" Xiao Si's voice suddenly came from the earphones, and Fu Liangtao watched the people next to him start walking towards the aisle in the center of the hall, and Xiao Si seemed to have finally found an opportunity to talk to Xu Jingjia.

Xu Jingjia was about to follow the others to the center of the hall, when Wen Yan turned around and looked at Xiao Si, but his gaze was quite unkind, or even a little hostile.

Xiao Si was a little surprised when she saw this, so she smiled, and instantly resolved the embarrassment flowing between the two. Then, Xiao Si said casually, "I'm also a student in the Wednesday night science class, we met, do you remember?"

Xu Jingjia only nodded expressionlessly at Xiao Simu, and without waiting for Xiao Si to respond, she walked forward, leaving Xiao Si alone, and followed the team in the central aisle. Since then, until the end of the ceremony, Xiao Si has not found a chance to talk to Xu Jingjia again.

When the ceremony was almost over, Fu Liangtao took the lead in leaving the hall and returned to the car, waiting for Xiao Si to come back to meet him.

Fu Liangtao closed his eyes in the car with exhaustion, thinking about whether he missed any details in the investigation of Li Zhou's case, so that all the clues at the moment were broken, and only Xu Jingjia was left.

And now, the plan to integrate into Xu Jingjia's life does not seem to be going well.

As the choir's singing on the phone stopped, the liturgy ended. After a while, Fu Liangtao listened to Xiao Si's voice coming from the earphones, but it was the voice of Xiao Si and others answering each other. I only heard Xiao Si ask, "May I ask what you just said about the girl with the ponytail?"

Fu Liangtao could imagine that the crowd in the hall was dispersing, and Xu Jingjia had already taken the first step. At this moment, Xiao Si was probably asking the people next to him for news.

After an abrupt pause, I heard Xiao Si smile kindly and say, "I don't mean anything else. Because you just mentioned about etiquette, and I'm new here, I don't know a lot about etiquette. Excuse me, did that girl do anything wrong?"

I only heard three or two women instantly gather around Xiao Si and talk nonsense, this one said that Xu Jingjia stood up late somewhere in the ceremony, and the other said that Xu Jingjia knelt early somewhere, and the posture of prayer was not right.

Xiao Si briefly listened to them explain the reason, and they left one by one, but only one woman did not leave, stayed, and asked Xiao Si, "Are you familiar with this girl?"

"No, we've only seen it in Wednesday's class, but we're not familiar with it." Xiao Si replied.

"Young man, I don't think you look like a bad person, so I told you, remind you, I don't want to tell you right and wrong!" At this point, he lowered his voice and continued, "You try to stay away from her, that girl doesn't have a job, and I don't know if there will be some other reason for coming here."

"Other reasons?" Xiao Si was surprised and asked.

"Don't you know? Just like those self-improvement courses run by the government, because the entry requirements are not high, there are many salespeople from different industries mixed with some other people. It's fine if it's just selling you products like insurance, but some of them don't...... Alas, in short, be careful yourself! I'm gone, too."
