However, during this period, the number of phantoms has been decreasing, and now there are only a handful of phantoms in the entire base city.

Each of the distorted phantoms was extremely large, all of them being tens of meters tall, or even hundreds of meters tall.

Lu Ning wasn't sure why these distorted phantoms left, but he understood that there was a big problem with this base city, and the problem was getting worse.

Considering that the entire third squad could disappear without a trace, Lu Ning did not have anyone split up to investigate.

After they entered the building, the security guard came over immediately.

"Who are you? What are you doing here?"

Lu Ning calmly took out his identification: "Mist Bureau investigation. Have you seen a Mist Bureau team here yesterday?"

Upon hearing that they were from the Bureau of Mystery, the security guards immediately stood at attention.

He quickly replied, "I've met you before."

Karen and the others' eyes lit up.

One of the middle-aged men asked curiously, "Where are they?"

"Huh? They came here to investigate yesterday, and then left?" The security guard was a little confused.

"Do you know where he went?" Lu Ning frowned and asked.

The security guard shook his head: "I don't know, but it seems to have gone to the left, probably towards Building 4?"

Lu Ning glanced at the entire high-rise building, then nodded slightly: "Understood."

He then led a few people to the left.

There were four buildings on the left. As soon as Lu Ning stepped into one of them, his eyes flickered.

The concentration of white fog in the lobby of this building was darker in many areas than in the surrounding areas.
