Ning Zhiheng looked at the structural diagram, pondered for a moment, and then said, "What you said is very important. It seems that entering from inside the building is simply impossible. We can only try to enter from the roof or through this ventilation shaft, but that is too difficult and we must plan it carefully!"

Ning Zhiheng was very confident in his skills. He felt that as long as he planned well, he might have a chance to sneak in. However, doing so was too risky. If he was not careful, he would get himself into trouble, and the consequences would be disastrous.

It seems that he should start with Kanda Yuzan first. Although it is only a temporary solution, it can delay things for a while. Moreover, it is relatively safe and simple. Fortunately, he had already made some plans, so he believed that the chances of success were relatively high.

Ning Zhiheng instructed, "I will take action immediately. During this period, you must not participate in anything related to the printing base. Otherwise, if any problems arise, you could easily be implicated."

"Yes!" He Siming nodded in agreement.

Upon returning to the Fujiwara Company, Ning Zhiheng immediately notified the Tan Mansion in the foreign concession that evening to dispatch a translator fluent in Japanese to Shanghai to await further instructions.

Ning Zhiheng has always had several translators under his command who were brought back from the Wuhan period and are proficient in Japanese. For a long time, they have been responsible for eavesdropping and translation in his businesses, as well as teaching Japanese to intelligence personnel. Now many intelligence personnel can understand Japanese, but their spoken Japanese is still not very fluent. Among them, Zuo Rou's Japanese has improved the fastest. With her hard work, she is now quite fluent in Japanese, but she still has some accent issues.

Ning Zhiheng now needs someone fluent in Japanese to assist with his upcoming operations, but apart from Yi Hua'an, whose Japanese is indistinguishable from a native speaker, he has no one else available.

Ning Zhiheng would certainly not let Yi Huaan take this risk; if things went wrong, the consequences would be unpredictable.

Three days later, one evening, in a house in a Japanese neighborhood, Shinsaku Yamada had just returned home from get off work. When he opened the door, he found the house completely dark.

He felt a pang of anxiety. His wife and son were at home. Normally, when he returned home, his wife would have greeted him warmly, helped him change his clothes and shoes, and his son would have run out and jumped into his arms.

But there was no one in the house today. He reached out and turned on the light, and the house was suddenly bright.

Suddenly he noticed a young man sitting cross-legged in his living room, looking at him with a calm smile.

Yamada Shinkaku instinctively reached for the wooden stick behind the door, but at that moment, he felt a gun pressed against his lower back. He was then pushed into the room, and the person behind him also came in and closed the door tightly.

"Mr. Yamada, my name is Matsui Keio. Please don't misunderstand, we are not bad people. We have come here to discuss a business deal with you!" the man in the middle of the living room said softly.

"What do you want to talk about? Where are my wife and son?" Yamada Shinsaku said with a gloomy expression.

He looked around, but there was no sign of his family in the kitchen or the bedroom.

"No need to look anymore, Yamada-kun, I've already taken the lady and the child away!" Matsui Keio said softly.

Yamada Shinkaku felt his blood rush to his head and shouted angrily, "Who are you? What do you want? Release my family right now, or I'll call the police!"

But as soon as he uttered those words, the gunman behind him struck him hard on the back with the butt of his rifle. Yamada Shinsaku felt a sharp pain in his back and was slammed to the ground by a great force, falling face-first in front of Matsui Keio.

Matsui Keio frowned and waved his hand, at which point the gunman took a step back.

After a while, Yamada Shinkaku slowly straightened up, staring at the other person with hatred in his eyes.

"Yamada-kun, you're being too impulsive. I've already said we meant no harm; we're just discussing a business deal."

At this point, Matsui Keio took out a small leather suitcase from behind him, pushed it in front of Yamada Shinkaku, and then opened the suitcase himself, revealing a suitcase full of banknotes in front of Yamada Shinkaku.
