Fortunately, after more than ten minutes, the toilet was finally empty, and Yue Jiuling dared to sneak out.

Just as she sneaked out, Ya Zi arrived. However, as soon as Ya Zi saw Yue Jiuling, he covered his mouth and chuckled. He said, "Oh dear, you've had a tough time, Comrade Jiuling. You've really had a hard time today, being trapped for so long."

"Come on, why didn't you tell me you needed outside help? You could have let me use outside help too! Now I had to go in myself and get trapped for so long. You have no idea how long it took one guy to detox, and then there was the second one. The farts he was letting out were awful! My god, I felt so awful!"

Yue Jiuling looked at Ya Zi with a pale face, then poured out her grievances to him.

As Ya Zi listened to Yue Jiuling's miserable experience, he covered his mouth and chuckled. He said, "Wow, you're really in a terrible situation. Luckily, she didn't have diarrhea and just sat there and wouldn't move, otherwise you might still be stuck here."

Yue Jiuling took out her phone and looked at the group messages, saying, "That's right, damn it, I'm really impressed. I'll probably never forget this mission. No wonder we had to eat so much this morning. Now, just thinking about what happened earlier makes me not want to eat lunch."

"Hahaha~ It's okay, let's go somewhere else to wash our eyes, and eat later."

Ya Zi said with a smile.

Holding up his black plastic bag, he said, "Did you only fill the toilet on the first floor with water? What about the other places?"

"We only installed the one on the first floor. By the way, it seems there's more than one toilet on the first floor. Let's look for other toilets. We need to fill each one with a little water."

Yue Jiuling started asking the security guard if there were any other restrooms on the first floor of the mall.

Sure enough, the security guard said there were three restrooms on the first floor of the mall, and they were all in separate areas.

When Yue Jiuling returned, she told Ya Zi, "We found out there are two more. One is next to the entrance of the shopping center, and the other is in the parking lot outside. Let's go to the shopping center first."

Ya Zi nodded, and then he and Yue Jiuling followed the signs to the second restroom.

This time, getting water was much easier. Yue Jiuling went into the women's restroom, and Ya Zi went into the men's restroom. The two of them came out in less than a minute, and then headed outside the mall to find a parking lot.

Going to the restroom near the parking lot was a bit of a hassle, because there were only two stalls and several people were in line. So Yue Jiuling and Ya Zi had to wait in line for five or six minutes before they could get water.

After sealing the bag containing the toilet water and noting its location, Yue Jiuling looked at the shopping mall in front of her and complained, "Tsk tsk, big shopping malls are really something else. Even the toilets are on one floor! Aren't they going to kill us with exhaustion?"

Ya Zi laughed and said, "Yeah, look, there are still more than ten floors here. We have to go up to the office building on top. I wonder if there will be a lot of small restrooms inside. That's going to kill us."

"Well, there's nothing we can do. Our killer isn't an ordinary human being, so we can't overlook any of the toilets. We need to investigate the water quality and the toilet cleaners used!"

Yue Jiuling shook her head helplessly and re-entered the mall, then took the elevator to the second floor to find a restroom.

The second floor of the mall is also for shopping, and the interior is nicely decorated. Following the signs, the two of them found two restrooms, including several accessible restrooms for the disabled.

When Yue Jiuling found the third one, she encountered another problem. A three- or four-year-old boy was afraid to be outside by himself and insisted on going into the women's restroom with his mother. However, the mother felt it was inappropriate to take him in, so the boy started crying at the entrance of the women's restroom. In the end, Yue Jiuling offered to help the mother stay with the boy, which finally stopped him from crying.

A few minutes later, after the boy's mother came out, when Yue Jiuling went in, Ya Zi had already filled the water in the men's restroom, and only Yue Jiuling's side was left to fill.

"Young Master Long, wait for me, I'll go in now."

Yue Jiuling took out the sealed bag and went inside, only to find that the cubicles were full and there were many people queuing up.

Only then did she remember that while she was outside, people had been constantly entering and leaving the restroom, so it was now very crowded with people queuing up.

Yue Jiuling glanced at the women queuing inside, then helplessly sent a message to Ya Zi saying: "Find a place to sit down yourself, I reckon the queue will be long again."
