After watching the secretary leave, only Karasawa and Koshimizu Nanatsuki were left by the machine.

Because they were waiting for the other party to call, the two did not walk around, but just looked at the machine beside them curiously. After all, if this kind of thing is not used in related places, it is really rare to see it.

But when the two came to the top of the machine, the protruding cylinder caught their attention.

"Is this... a heating column?" Tang Ze reached out and grabbed the handle on the cylinder and pulled it out, revealing the long column shaft.

The surface of this cylinder is not smooth, but has a lot of "～"-shaped protrusions, which are connected one after another to form a "§"-shaped first part.

Looking at the familiar pattern, the two looked at each other and finally understood why there was such a strange mark on the deceased's neck.

"The deceased has this wound on her body, which means that she was killed at the scene where there was a soup processing machine." Nanatsuki Koshimizu looked at the machine cylinder with sharp eyes.

"It keeps happening, and the heating column is still exposed." Tang Ze glanced at the two people who were talking on the phone and whispered, "Take photos for evidence."

Koshimizu Nanatsuki quickly took out her phone to take a picture of the cylinder, but just as the flash went off, the next moment they heard Ritsujin Miura's excited voice approaching them.

"Anyway, we can't do this. We have to add it to the equipment, okay?"

Hearing the sound getting closer, Nanatsuki Koshimizu quickly put away her phone, while Karasawa pushed the handle to push the cylinder back into the heating machine.

"I'm so sorry, there were some problems at the factory in Italy."

Lichen Sanpu hung up the phone and smiled apologetically at the two people walking towards him. "I need to take care of things over there later. Do you have anything else you want to ask?"

“Thank you for taking the time out of your busy schedule.”

He bowed slightly, and Ritsujin Sanura immediately returned the greeting and walked away quickly. It was obvious that the previous incident made the other party very impatient.

Because they had obtained important information, Tang Ze and the others were afraid of alerting the enemy, so they did not question the employees in the factory, but left the factory directly.

Tang Ze also received another call from Detective Mizukura and obtained important information.

The true form of the pathogen was finally detected by the hospital.
