Chapter 1286 Infiltration in Public

9 p.m.

The pharmaceutical factory was empty. Workers were working overtime to produce drugs. They even jogged to the toilet. Only teams of guards passed by from time to time.

After another group of guards walked away, the black shadow figured out the patrol patterns and time, quietly walked out from the corner, and went straight to the research center in the deepest part of the factory.

Although the Germans did not find out the internal layout of the pharmaceutical factory, apart from the factory buildings and office areas, this was the only place in the pharmaceutical factory where there was no sound of machines but was brightly lit, and it also had the highest density of guards, making it obviously a strategic location.

It is not difficult for a qualified intelligence officer to analyze this point, so Zuo Zhong does not like to defend. The enemy can make countless mistakes, and one mistake means failure.

The black shadow moved quickly in the shadows outside the light, sometimes lying under the stairs, sometimes hiding behind trees, avoiding multiple groups of guards and approaching the target little by little.

"Chun Yang, when do you think the other party will take action?" Inside the surveillance point, Zuo Zhong asked with interest while admiring the Germans' performance.

Wu Chunyang looked at his watch and gave his guess: "In the early morning, when the workers change shifts, there will be a large number of people moving around in the factory. That is the best time to act."

"What about the withdrawal time?" Zuo Chong asked again.

"The next time the glass factory delivers the goods." Wu Chunyang replied without hesitation.

Zuo Zhong nodded slightly. There were still two or three days before the next delivery, which meant that the German agents would have to stay undercover for at least another 48 hours. The Abwehr people were still quite capable, at least more professional than the Central Bureau of Investigation.

However, if Zuo Zhong had to choose, he would set fire and create chaos to get away, because the longer it takes, the more uncertainties there will be.

But there are always unexpected things. If Mu He is determined to get the formula and run away, he might burn down the entire camp.

Realizing that the pharmaceutical factory might be in danger, Zuo Zhong whispered to the little spy next to him to prepare the water cannon. If the Germans thought the same as he did, the Zuo family would suffer a great loss.

At midnight, the wind gradually picked up.

The dark shadow that had been lurking outside the research center was hiding in the bushes, with its eyes looking towards the gate of the building and its ears listening to the movements around it, appearing extremely vigilant.

Tap, tap, tap, a series of footsteps came from far away, and several guards came to the door of the research center and chatted with the people inside.

The black shadow counted the sounds in his mind to determine the number of people inside the door. When he counted to the fourth person, he immediately gave up his plan to enter through the door.

One person might have a visual blind spot, but with four people cooperating with each other, even if they are all amateurs, he won't stand a chance.

The black shadow supported himself on the ground with his hands and slowly retreated into the darkness, then circled around the research center, trying to find another entrance.

Suddenly, the shadow's gaze stopped on the large skylight on the top of the sawtooth-shaped factory building, which is a signature feature of Bauhaus architecture. It can ensure uniform lighting indoors and facilitate refined industrial production.

At this moment, these skylights became the best breakthrough points. The black shadow rolled up his sleeves and looked at the luminous watch on his wrist①, then covered the watch and waited quietly for the action window to arrive.

At eleven o'clock, the patrolling guard passed by again.

Listening to the footsteps slowly fading away, the black shadow stood up and ran to the side of the factory building. Then he took out a flying claw with a rope hanging from his back, spun it a few times in the air, and swung it upwards.

The flying claw wrapped in cloth firmly grasped the eaves. The black shadow held the rope tightly, pushed the wall with his feet, climbed to the top of the factory building and retracted the rope without making any sound.

As soon as the rope was retracted, the shadow of a guard appeared in the corner. This was a mobile patrol. The black shadow was lying on the ceiling, looking at the night sky with a calm expression.

The mobile sentry gradually went away. The black shadow turned over and crawled to the skylight and looked inside. He saw many experimental equipment and a safe in the factory, and four guards were chatting in the porch opposite.

After confirming the guard's position again and again, the black figure quietly moved to the skylight at the innermost side of the factory, took out a celluloid (old-style plastic) card from his pocket, inserted it into the gap of the window, slid it up and down, and quickly moved the lock tongue out of the card slot.

This type of handle-type window lock has very poor security. Even a new intelligence officer who has just entered the industry can open the window without damaging the glass.

After solving the first "obstacle", the black shadow did not rush to open the window, but took out an exquisite celluloid oil bottle from his treasure bag-like pocket.

He brought the spout of the oil bottle close to the skylight and pinched it lightly twice. A few drops of greasy but colorless and odorless lubricant dripped onto the hinges and handles. He performed the whole set of movements with great skill, as if he had practiced them countless times in advance.

After doing all this, the black shadow curled up at the window, looking at his watch and keeping an eye on the movements of the four guards.

At about twelve o'clock, the doorbell and the noise of the workers rang outside, and four guards entered the factory together, one of them shining a flashlight at the skylight. The flashlight flashed across the glass, and the shadow closed his eyes and listened to the footsteps of the guards, constructing the patrol route and position of the four people in his mind. When the last guard walked out of the factory, he suddenly opened his eyes.

Open the window, throw the rope, slide down, and take cover.

In just over ten seconds, the black shadow successfully sneaked into the heavily guarded research center and directly locked its target on the safe without even looking at the experimental equipment along the way.

Before leaving, Mu He asked scientists to provide relevant training to his subordinates. Black Shadow knew that the most important things in a pharmaceutical laboratory are data and experimental logs, and they must be in the safe.

Squatting in front of the safe, Shadow recognized its model at a glance: a commercial V-type safe from Rudolf Fischer.

This safe has a high-strength anti-theft design that can resist picking, drilling and other destructive means. The cabinet is made of thick steel and fire-resistant fillings to keep the contents safe in high temperatures.

However, what the outside world does not know is that the largest shareholder of Rudolf Fischer Company is the German government, or a shell company of Abwehr.

Black Shadow was delighted but remained calm, and after checking whether the safe was equipped with an external alarm, he began to try to crack the code.

Although the password of the V-type safe can be changed, it can only be changed according to the fixed password table provided by Fischer Company. In order to facilitate mass production, the linkage points of the password disks of similar mechanical safes are all in the same area.

Therefore, as long as you find the first password, the rest will be easy. Remembering the Fischer Company password table is a necessary skill for every German agent. After all, it was the world's largest safe manufacturer before the war.

Figuring out the first combination was easy enough. Mechanical safes rely on the physical structure of dials and gears to work. There is a series of dials inside the lock, and each dial corresponds to a number.

In the correct combination, the dials align, allowing the deadbolt to unlock and the safe to open.

Because of tiny physical differences between mechanical parts, a skilled cracker can infer the correct area of ​​the combination by observing the dial or listening to the sound changes inside the lock. This area generally has an error of five scale marks.

The black shadow looked in the direction of the porch, raised his hand and turned the dial clockwise, put his ear close to the cabinet and listened to the sound of the machinery inside, with his attention highly concentrated.

It didn't take him long to determine the possible range of the first password, and then he tried different password combinations based on the numbers in the range, relying entirely on his memory and hand speed.

Today, the goddess of luck seemed to be on the side of the German. The black shadow only eliminated two password combinations. With the input of the third combination, he pulled the handle and the door of the sturdy safe opened②.

Through the gap, one can see that there are many documents stored in the cabinet. Shadow notes the placement and angle of the documents and quickly takes pictures with a spy camera.

After getting the information he wanted, the black shadow calmly restored the documents and the safe dial to their original state, climbed back to the roof along the rope, and finally did not forget to close the skylight again with a celluloid card.

Behind a wall of the research center, Zuo Zhong, Gu Qi and Wu Chunyang stood in front of the observation hole with different expressions. Zuo Zhong was smiling, but Gu Qi and Wu Chunyang were very serious.

"Commander-in-Chief, the other party's performance is very professional. We must pay more attention to Abwehr."

Gu Qi was the first to express his opinion. From the series of performances of that person just now, it can be seen that the quality of Abwehr's personnel is not worse than that of the Military Control Commission, and even exceeds it in some aspects.

Putting aside other things, just talking about cracking the safe, no one in the Military Control Commission could do it so quickly, including Wu Chunyang, who had the best intelligence skills.

Zuo Chong saw that the two were somewhat frustrated, and objectively commented: "Don't be proud, and don't belittle yourself. If it were an American safe, the Germans would also need a longer time to crack it.

What is important is that we can learn something from this incident, and when we return, we can issue an order to the Kuomintang-controlled areas and overseas stations, telling them not to use safes made in Japan or in the host country. "

After he finished speaking, he paused for a few seconds and said with a smile: "As for Abwehr, I have never underestimated them. Brothers, be careful and don't scare the guests. We still need to rely on this guy to perform the next show."

Gu Qi and Wu Chunyang were shocked. If the Germans could leave a back door in the safe, then why couldn't the Japanese and Americans? The answer was obviously no.

The overseas district stations are still okay, but if there is a problem with the Japanese-made safes storing confidential documents in the local district stations, the brothers lurking in the enemy-occupied areas will be in danger, so we must be cautious about this.

No matter what, the country is still weak. If the Republic of China had its own high-end safe factory, why would they buy foreign products?

The scene fell into silence, but the machines in the pharmaceutical factory continued to roar. Bottles of penicillin were filled into brown glass bottles and sealed with wax caps.

Two days later in the evening, the glass factory truck stopped in front of the warehouse. The driver offered the guard a cigarette and apologized for what happened last time.

Don't hit a smiling person. The guards accepted the other party's apology with a smile, and gathered together to smoke cigarettes. The black shadow walked to the side of the car and got into the secret compartment as if no one was around.
