There are a lot of people and cars entering the small courtyard where the building is located, and the security guard standing at the security gate swiped the pass and let it go directly, which is not as strict as imagined.

After observing the café for half an hour, Wen Ya found that there was still something different, and several cars that entered the courtyard did not stop in the garage, but drove directly into the building.

Obviously, the high-rise parking lot on one of the floors of the building is not open to the public.

After the cars drove in, they never showed up again, and there was no exit to or from the building.

After more than ten minutes, Wen Ya and Jin Buchang checked out and left the café, at this time, the security guard standing at the security gate had already looked several times in the direction of the café and the two of them.

The two didn't dare to be careless, and when they left the café, Wen Ya and Jin Buchang kept their previous speed and demeanor and left the bustling street.

"There's something wrong with the building." On the way, Jin Buchang and Wen Ya exchanged words in a whisper.

"I have paid attention to and observed, although the building is ordinary, starting from the security gate, not only is there a guard, but there are a lot of testing equipment in the open and in the dark, and the internal security of the building must be more rigorous."

"The defensive measures are loose on the outside and tight on the inside, even the security guards at the door are so vigilant, the wolf is right, if you want to infiltrate the building from the front, it is basically impossible, we have to think long-term." Wen Ya nodded approvingly.

Back at the Red Sand Mercenary Station, the Wolf is looking at the three-dimensional architectural plan of the small building.

On the architectural drawings, various lines and color blocks of different thicknesses represent the details of the building's heavy columns and structure.

"Phantom wolf, without on-site investigation and infrared detection, how do you know the internal situation of the headquarters building of the Smart Foundation?" Wen Ya asked a curious question.

"The building of the Wisdom Foundation is at least 100 years old, and the internal structure of such an old building is the same, and I have all the information on this." The wolf spoke.

"The side door is powerful." Jin Bu changed his sentence and told the wolf what he saw in the café.

"Well, a hundred years ago, the building space was very large, and it was normal to have a high-rise parking lot, and I am now doing the final calculations, no matter how complex the underground maze is, the exit location will definitely be at the underground entrance of the building."

"When I was looking for information just now, I found a strong man who designed the underground labyrinth in line with the period of this building."

"This designer likes bells and whistles and twists and pranks in the opposite direction, as long as the exit is determined, according to the design characteristics of this design, I have a great deal of confidence to get through the underground maze." The wolf said confidently.

"That's good." Wen Ya is in a good mood, and at this time, the ability to deviate from the door is fully exerted.

Wen Ya and Jin Buchang didn't go away, and quietly accompanied the ghost wolf on the side, and after half an hour, the ghost wolf finally completed the last calculation.

On the drawing paper, the lines of the underground maze were much more complicated than before, and Wen Ya stared at the drawings for a long time before she could barely find the exit of the underground maze.

Just looking at a drawing is so complicated, you can imagine how complicated a real underground labyrinth is.

"Phantom wolf, I have a question, what if I go through the underground maze and there is no exit at the exit?" Jin Buchang's head is swollen, and if the underground maze is to prevent people from infiltrating from underground, it is not impossible to design a closed underground labyrinth.
