As for the secret realm outside the city, it must be explored by the City Defense Office to determine the extent of the danger. If there is a chance, they will obtain the core of the secret realm. If there is no chance, they will have to stay there and try their best to ensure that the creatures in the secret realm do not escape.

Only secret realms with extremely high danger levels, like the "Beast Disaster" secret realm, will require military assistance in defense, but things like exploring secret realms can only be done by the City Defense Office itself.

A few days later, the suspect in Wang Bo's case was finally identified as Zhang Zibing. After all, his original occupation was too special, an axe thrower, and the weapon he used was also relatively niche, so he was identified in just a few days. Moreover, after comparison, the marks on the victim's wounds were completely consistent with the weapons Zhang Zibing usually used. Based on this point alone, Zhang Zibing could be summoned.

City Defense Office, in the meeting room.

Wu Jie played the slides while explaining.

"Zhang Zibing is from Songtao City. His parents died three years ago. He left Songtao City and went to live with his uncle Zhang Guotao in the neighboring Haihua City. A year later, he became a secret realm apostle. His initial occupation was axe thrower. He used five throwing axes and a one-handed double-edged axe as weapons..."

On the projection screen appeared pictures of Zhang Zibing using weapons, as well as some previous battle scenes, as well as 3D simulations of the dead's wounds and weapons, which were almost completely consistent.

"Three months ago, Zhang Zibing and his apostle team returned to Songtao City for unknown reasons. During that time, they went to explore the secret land outside the city together. A few days ago, Zhang Zibing suddenly disappeared. Now there are only four people left in that apostle team..."

…

After the meeting, the City Defense Office issued an arrest warrant for Zhang Zibing and summoned the other four members of Zhang Zibing's apostle team.

Zhang Zibing's joining the Mist organization was a personal act, and he did not tell other members of his team. On the one hand, it was to keep it confidential. On the other hand, it was because Zhang Zibing knew that no matter how many people went, only one person would inherit the Mist number in the end, and he had a better chance of succession.

In the summoning room of the City Defense Office, the other four members of Zhang Zibing's apostle team were all placed in separate rooms. On the monitoring screen, the four of them seemed a little restless, with nervous expressions on their faces.

"It seems that they don't know anything about Zhang Zibing's affairs!" Li Dong adjusted his glasses and frowned slightly.

After the four were summoned to the City Defense Office, they were detained separately and deliberately left alone for more than an hour. Judging from the expressions and micro-movements of these four people, they seemed to be unaware that Zhang Zibing had any connection with the Mist Organization.

"Let's start asking questions and see if we can find other clues..." Li Dong sighed and said to several staff members beside him.

In the four interrogation rooms, two staff members began to question the four apostles respectively.

If they are in a secret realm, or even in the wild, many secret realm apostles do not take the City Guard Office seriously at all. Some are even full of malice towards the City Guard Office and will actively attack the apostles of the City Guard Office.

But in Songtao City, the City Defense Office has absolute authority. As a state machine, it cannot be resisted by one or two apostles, or one or two apostle teams.

In the summoning room, two staff members from the City Defense Office walked in expressionlessly and began to question Zhang Zibing's apostle team.

"Name?"

"Zhao, Zhao Hu!"

"age?"

…

After a brief inquiry, a staff member asked directly: "As a member of Zhang Zibing's Apostle Team, do you know what Zhang Zibing did after returning to Songtao City?"

"Brother Bing, no, Zhang Zibing took us back to Songtao City and said that there is a secret realm here that can quickly improve our apostle experience. However, we have been searching in the wild for several months since we came to Songtao City, but we have not found the secret realm that Zhang Zibing mentioned..." Zhao Hu stuttered at first, but he spoke more and more fluently. He also understood that Zhang Zibing must have done something to implicate them.

"Leader, we really don't know anything about Zhang Zibing. That guy is very cunning. He has been particularly mysterious in recent times and always goes out alone..." Zhao Hu was full of resentment and racked his brains to recall all of Zhang Zibing's actions.

More than a week ago, Zhang Zibing disappeared inexplicably. Several people were puzzled, but they thought that Zhang Zibing had some private matters that he was not convenient to tell them, so they did not pay attention to it.

Unexpectedly, they attracted the attention of the people from the City Defense Office, who "invited" all four of them back to the City Defense Office.

"By the way, leader, recently, every time Zhang Zibing comes back, he has a strange smell on his body. The smell is very special, like the smell of burning monsters in a secret realm..." Zhao Hu's eyes lit up and he suddenly said.

"Oh, the smell of burning monsters in the secret realm?" The two investigators looked at each other, a barely perceptible smile appeared on their faces, and they said to Zhao Hu in a softer tone, "Tell me about it in detail."

"Oh, yes, yes, leader!" Zhao Hu also became a little excited and continued, "The smell is very faint. If it were an ordinary person, they would definitely not care about it. But after I became an apostle of the secret realm, my sense of smell has been enhanced a lot. I can smell many smells that other people can't smell..."

"Zhang Zibing has been acting mysterious for a week. He often goes out alone and stays out for most of the day. Every time he comes back, he has that smell on him..."

There is no wrong version in the 1619 book forum!

"The smell of burning monsters in the secret realm is different from that of burning ordinary beasts. There is a special strange smell, not a stinky smell, but a strange smell..."

"Are you sure this is the smell of burning monsters from the secret realm?" an investigator couldn't help but ask.

"Sure, it must be the smell of burning monsters in the secret realm!" Zhao Hu said firmly, "I have smelled that smell before. Someone in the secret realm has used fire magic to attack the creatures inside. Whether it is wild beasts, natives, or even flowers and trees, when they are burned, there will be that strange smell. It is the same in every secret realm. However, burning anything in the real world will not have that smell..."

…

A few hours later, the investigators handed in the interrogation records of several people, and especially put Zhao Hu's interrogation record at the top.

"Director, we have found something!" Wu Jie came to the conference room with Zhao Hu's interrogation record and said, "According to Zhao Hu's interrogation confession, the place where Zhang Zibing came into contact with the Mist Organization has been basically confirmed. It's right here!"

As she spoke, Wu Jie turned on the projector and played a map of Songtao City. She drew a red circle in the southwest corner of Songtao City and said, "Gangxiang. Preliminary judgment shows that Zhang Zibing and the Mist Organization always come into contact in Gangxiang!"

"Gangxiang owns a secret biological refining factory, Yuansheng Oil Industry! Its main business is to purchase the corpses of creatures in the secret realm for refining and manufacturing an industrial lubricant. During the manufacturing process, it will cause some air pollution and produce a strange smell. This strange smell is caused by the world power dissipated during the refining process. It is a unique smell of the secret monsters. It will not cause any harm to the human body, but the smell is very sticky and it is difficult to get rid of it..."
