If the man remains defiant and does not utter a word under the brutal electric shocks, then he will face long-term, endless torture until death.

However, if this man fails to endure the severe torture and ultimately succumbs to it, defecting and becoming a traitor, then his comrades or the organization behind him will certainly suffer enormous losses because of his defection.

Moreover, this possibility is very high, because Ning Zhiheng knows that in this world, whether Chinese or Japanese, there are very few true warriors on both sides who can truly be unyielding to the death, who can ignore the inhuman torture they suffer and endure the severe punishment with unwavering faith and willpower.

Of all the spies Ning Zhiheng personally arrested, only Fu Cheng survived the severe torture, but in the end he couldn't withstand the electric shock and died on the spot from his injuries.

The other Japanese spies couldn't endure it, but today, Kosuke Ikeda knew he couldn't take it anymore. So he bit his tongue, cutting off his own path to confession and surrender. This was actually a death wish; he would rather die than face the endless inhuman torture.

Ning Zhiheng knew that the man in the fourth picture was very important. He had to memorize him carefully. Whether he was a member of the Kuomintang or the underground party, he was his comrade. If he couldn't hold on and defected to the enemy, it would have serious consequences. He had to be prepared.

The fifth image contains the information Ning Zhiheng needs most right now. The scene depicted in the image is likely the other members of the Japanese investigation team, who are compiling data together late at night. There are a total of eight members.

According to Kazunari Yamauchi's account, there are usually two people working in a group for security duties, meaning there are a total of ten group members. It seems that Kazunari Yamauchi was not lying about this.

The man who attracted everyone's attention should be Kenji Takeshita, the leader of the investigation team. Kosuke Ikeda had a deep impression of him, and his appearance was clearly visible in the footage.

Of the scenes captured from Kosuke Ikeda's memory this time, only the Chinese man being tortured and Kenji Takeshita, the leader of the Japanese investigation team, are the most valuable. Kenji Takeshita will come into contact with the Chinese man during the arrest operation tonight, so there is no need to draw him. However, the Chinese man's appearance must be drawn.

Ning Zhiheng opened the drawer and took out a stack of white paper and paintbrushes. He had to draw them out while the memories were still vivid, otherwise the memories would become blurred over time.

He was completely absorbed in his work and drew the portrait of the Chinese man with great speed. It took him more than an hour to complete the portrait. Then he picked up the portrait, went to the safe, opened it, and put the portrait inside.

Just then, there was a knock on the door; it was Sun Jiacheng returning.

"How's the terrain reconnaissance going? Is the situation there suitable for an arrest?" Ning Zhiheng asked.

"Team leader, I've surveyed the terrain thoroughly. Here's a simplified topographical map I drew," Sun Jiacheng said, handing a simple map to Ning Zhiheng.

Ning Zhiheng took it, examined it carefully, and nodded, saying, "This Daming Cotton Mill has been abandoned for a long time, and there aren't many people living around it. It's a good hiding place, but it also makes it easier for us to make a concentrated arrest."

However, there's one problem: this cotton mill is quite large, and the layout is rather complex. If we alert them and they rush out of the old warehouse, searching such a large mill with so many workshops and buildings will be quite difficult."

Sun Jiacheng nodded and said, "I only surveyed the perimeter of the cotton mill. As for the inside of the mill, I couldn't determine the location of their observation posts, so I didn't rush in. I found an old worker from a nearby cotton mill and asked him about the terrain inside, which is how I drew a map of the inside of the mill."

Ning Zhiheng was also worried. After thinking about it, he decided that he still needed to ask about these details clearly, otherwise he would not be able to be sure of the specific arrangements for his actions.

It seems we still need to interrogate Kazunari Yamauchi again to find out their patterns of action and guard positions.

Ning Zhiheng and Sun Jiacheng quickly went to the interrogation department and interrogated Yamauchi Kazunari again.

At this moment, Kazunari Yamauchi was covered in white bandages. He had just been severely tortured, and his body was covered in wounds. His injuries were so serious that he could no longer move.

Ning Zhiheng rushed to the cell where he was being held, placed the simple map drawn by Sun Jiacheng in front of him, and asked again, "When you were in charge of guarding the cotton mill, where were the observation posts usually located?"

Yamauchi Kazunari slightly opened his swollen eyes and looked around, saying weakly, "There are two people on guard duty. Usually, one is near the entrance of the cotton mill, and the other is outside the old warehouse. They take turns on guard duty every two hours. There are no specific locations; they are usually mobile sentries."
