"Could it have been sabotaged? Otherwise, why would it be malfunctioning?"

The two people rushed upstairs, shouting as they ran, "It's a ghostly invasion! Everyone, use your talismans!"

While they were shouting, Mu Xiaoyi had already prepared a bunch of talismans. Holding the talismans, she said, "It seems that girl has made a lot of progress these past few days. Her ghost gu can even break into our barrier. Be careful. Whether we can catch the murderer and solve the case as soon as possible depends on today."

Inside the basement, Yue Jiuling, Bai Xinyu, and Xiao Baicai were sitting on a row of benches, looking at the person opposite them, who was the shop owner.

Yue Jiuling said to the shop owner, "How about it? Can you feel it? Your sister is already on her way to save you."

In fact, the shop owner had already sensed the ghostly invasion, but he pretended to know nothing and said, "Oh, really? Then shouldn't you let me go?"

Yue Jiuling casually stretched out her foot and stepped on a black insect that had just emerged from the ground, saying, "Of course, as long as we catch your sister, we will definitely release you. After all, you are just an innocent bait."

The black worm was stepped on by Yue Jiuling, and then it shrank into the ground. The next second, it crawled out from another direction, but it was stepped on again as soon as it came out. This time, it was crushed to death and turned into a puddle of black water.

Little Cabbage was terrified of the insects. Trembling, he pointed behind the shop owner inside the cell and said to Yue Jiuling, "Sister, they...they're all here!"

All they could see was that the walls of the cell were covered with countless black insects. These insects were different from the ghost insects they had encountered before, because this time they all had wings.

Bai Xinyu sneered when she saw the insects. She pulled out a handful of special talismans and said, "Heh~ Come on, today I'll make sure you don't leave alive!"

Yue Jiuling laughed when she saw Bai Xinyu's appearance. She said, "Haha~ Xinyu, you look just like a celestial master. If I didn't know you were a demon, I would have thought you were a celestial master from the human realm."

Bai Xinyu laughed too: "Haha, it's all Xiaoyi's fault. If it weren't for her special talisman that we demons could use, I wouldn't have learned from them."

More and more ghost Gu appeared in the prison, but this time the ghost Gu seemed to be quite intelligent. They knew that the talisman in Bai Xinyu's hand was not to be trifled with, so none of them took the initiative to attack.

Seeing that the shop owner was surrounded by the ghost gu, Yue Jiuling knew they were trying to escape. So she immediately took the talismans from Bai Xinyu's hand and threw them all into the cell. Then, while the ghost gu were dodging the talismans, she quickly opened the iron gate and ran inside!

"Walk!"

Yue Jiuling grabbed the shop owner and tried to take him away, but he resisted. When the shop owner saw that the door was open, he immediately attacked Yue Jiuling and ran out of the cell!

Upon seeing this, Bai Xinyu immediately went to intercept them, and Xiao Baicai followed to help, because she was worried that if the shop owner really ran away, it would be even more difficult to catch the murderer.

When Yue Jiuling saw the shop owner run out, she panicked and tried to chase after him. But before she could run a few steps, she discovered that many ghost gu had appeared out of thin air at the door. Then, the ghost gu slowly surged together and finally merged into a human shape!

"Wow! I didn't expect you to be so good. It's only been a few days and you've already improved so much."

Seeing that she was trapped, Yue Jiuling simply stopped running and stood with her hands on her hips, talking to the humanoid ghost Gu.

After hearing this, the humanoid ghost Gu also spoke, and it was a female voice: "Hmph~ I'm a genius, it's normal for me to have achieved this in such a short time. As for you, just wait to become a nutritious dinner for my darlings!"

After the humanoid ghost finished speaking, it slowly wriggled and revealed a female body. The person who appeared was none other than the murderer girl!

When Yue Jiuling saw her appear, she smiled and said, "It really is you. But it's good that you came. It saves us from always worrying that you wouldn't come, and then we wouldn't be able to let your brother go and would have to keep raising him. Fortunately, you didn't disappoint us and finally came today."
