Nine o'clock in the evening.

The pharmaceutical factory area was empty, and the workers worked overtime in the factory to produce medicines. Even when going to the toilet, they trotted all the way, with only teams of guards passing by from time to time.

After another group of guards walked away, the shadows understood the patrol rules and time, quietly walked out of the corner, and headed straight to the research center at the deepest part of the factory.

Although the Germans did not find out the internal layout of the pharmaceutical factory, except for the factory and office areas, the pharmaceutical factory only has no sound and bright lights. Moreover, the guard density is the highest, which is obviously a key location.

To analyze this point, it is not difficult for a qualified intelligence officer, so Zuo Chong does not like defense. The enemy can make mistakes countless times. If they make mistakes once, it means failure.

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

"Chunyang, when do you think the other party will act?" Zuo Chong asked in the surveillance point while admiring the German performance.

Wu Chunyang looked at his watch and expressed his speculation: "In the early morning, workers will change shifts and there will be a large number of personnel activities in the factory, which is the best time to move."

"Where is the withdrawal time?" Zuo Chong asked again.

"When the next delivery of the glass factory." Wu Chunyang replied without hesitation.

Zuo Chong nodded slightly. There were still two or three days before the next delivery, which means that the German agents would have to lurk for at least 48 hours. Abveer's people are still a little skilled, at least more professional than the Central Commission for Transport.

However, if Zuo Chong chooses, he will set fire to create chaos to escape, because the longer the time goes on, the more uncertain factors will be.

But everything is unexpected. If Muh made up his mind to get the recipe, he would run away, and maybe he would have a fire camp.

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

At midnight, the wind slowly becomes stronger.

The black shadows that had lurked outside the research center were hiding in the grass, with their eyes looking at the building gate, and their ears listening to the movements around them, showing special vigilance.

Da, da, da, a string of footsteps went from far to near, and several guards came to the door of the research center to chat with the people inside.

The sound of the black shadow silently counted in his heart to judge the number of people in the door. When the fourth person was counted, he immediately gave up his plan to enter through the door.

One person may have visual blind spots, but the four people cooperate with each other, even if they are all laymen, he will not have any chance.

The black shadow slowly retreated into the darkness with his hands, and then circled around the research center, trying to find other entrances.

Suddenly, the black shadow's eyes stayed on the large lighting skylight on the upper part of the zigzag factory. This is the hallmark feature of Bauhaus buildings, which can ensure uniform indoor light and facilitate refined industrial production.

At this moment, these skylights became the best breakthrough. Black Shadow rolled up her sleeves and looked at the luminous watch 1 on her wrist, then covered the watch, and quietly waited for the arrival of the action window.

At about 11 o'clock, the inspecting guard passed by again.

Hearing the footsteps slowly moving away, the black shadow stood up and ran to the edge of the factory, then took out a flying claw with a rope from behind and turned around in the air for a few times, then slammed upwards.

The flying claws wrapped in cloth strips firmly grasped the eaves. The black shadow held the rope tightly, stepped on the wall and climbed up to the top of the factory building, and retracted the rope, without making any noise during this period.

As soon as the rope was retracted, the shadow of the guard appeared in the corner of the wall. This was a mobile whistle for random patrols. The black shadow lay on the ceiling and looked at the night sky with a calm expression.

The mobile whistle gradually faded away, and the black shadow turned over and crawled to the skylight and looked inward. He saw many experimental equipment and a safe in the factory, and four guards chatted on the opposite porch.

After repeatedly confirming the position of the guard, the black shadow quietly moved to the skylight on the innermost side of the factory, took out a celluloid (old plastic) card from his pocket, stuffed it into the gap in the window and slid up and down, and quickly moved the lock tongue out of the slot.

This type of handle-type window lock is very poor in safety. Even new intelligence newcomers can open windows without destroying the glass.

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

He approached the oil spout near the skylight and gently pinched it on his hand twice. A few drops of greasy but colorless and odorless lubricating oil dripped on the hinge and handle. The whole set of movement was extremely skillful, as if he had practiced it countless times in advance.

After doing all this, the dark shadow curled up at the window, looking at the watch while always paying attention to the movements of the four guards.

At about twelve o'clock, an electric bell and the noise of workers rang outside. Four guards entered the factory together, and one of them shone the skylight on the flashlight.

The flashlight flashed across the glass, and the black shadow closed his eyes and listened to the guard's footsteps, constructing a patrol route and location for 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 hide.

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

Before leaving, Mulch asked scientists to conduct relevant training for his subordinates. Heiying knew that the most important thing in a pharmaceutical laboratory is data and experimental logs, and they must be in the safe.

Squatting in front of the safe, the Shadow recognized its model with just a glance, the commercial V-shaped safe of Rudolph Fischer.

This safe has a high-strength anti-theft design that can prevent lock picking, drilling and other destructive means. The cabinet is made of thick steel and fire-proof filler to keep the internal items safe at high temperatures.

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

The black shadow was still calm while being happy. After checking whether the safe was equipped with an external alarm, he began to try to crack the password.

This chapter is not over, please click on the next page to continue reading! Although V-shaped safes can be changed, they can only be replaced according to the fixed password table provided by Fischer. In order to facilitate batch manufacturing, similar mechanical safes password disk linkage points are in the same area.

Therefore, as long as you find the first password, the rest will be simple. Remember that the Fischer company password list is a necessary skill for every German agent, after all, it was the world's largest safe manufacturer before the war.

It is also easy to find the first password. The operation of the mechanical safe depends on the physical structure of the dial and gear. There is a series of dials inside the lock, and each dial corresponds to a number.

In the correct combination, these dials will line up in a straight line, allowing the latch to enter the unlocked state and the safe will be opened.

Due to the slight physical differences between mechanical parts, skilled crackers can infer the correct area of ​​the password by observing the turntable or listening to the sound changes inside the lock, which generally has five scale errors.

The black shadow looked at the direction of the porch, raised his hand and turned the dial clockwise, his ears pressed against the cabinet and listened to the sound of mechanical movement inside, and his attention was highly concentrated.

It didn't take long to determine the possible range of the first password, and then tried different password combinations based on the numbers in the range, which all depended on memory and speed in hand.

Today, the goddess of luck seemed to be on the side of the Germans. The black shadow only ruled out two password combinations. With the input of the third set of passwords, he pulled the handle and the solid safe opened the door.

Through the gap, you can see multiple files stored in the cabinet. The black shadow records the placement and angle of the files, and quickly completes the shooting with a spy camera.

After getting the information he wanted, the black shadow calmly restored the documents, restored the safe dial, climbed back to the roof along the rope, and finally closed the skylight 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 smiled, but Gu Qi and Wu Chunyang were very serious.

"Second post, the other party's performance is very professional. We must pay more attention to Abveer."

Gucci took the lead in expressing his opinion. From the series of performances of the man just now, it can be seen that Abveer's personnel quality is not worse than that of the military commander, and even exceeds that of some aspects.

Not to mention anything else, just talking about cracking the safe, no one in the Military Control Commission could do so quickly, including Wu Chunyang, the best intelligence technology.

Seeing that the two were a little frustrated, Zuo Chong objectively commented: "Don't be proud, and don't belittle yourself. If it's an American safe, the Germans will also take longer to crack it.

What is important is what we can learn through this matter. After returning, we ordered the Kuomintang-controlled district and overseas district stations so that they could not use safes produced in the country in their daily and domestic areas."

After saying that, he paused for a few seconds and said, "As for Abvell, I have never underestimated the other party. Let the brothers be careful not to scare the guests. We have to rely on this guy to sing the next play."

Guqi and Wu Chunyang were shocked. Can the Germans leave a back door in the safe, but the Japanese and Americans won’t? The answer is obviously no.

It’s okay for overseas stations. If there is a problem with the daily safe with confidential documents in local stations, the brothers lurking in the enemy-occupied area will be in danger. You must be wary of this.

If one thousand words are said, the country is still weak. If the Republic of China had its own high-end safe factory, why would they buy foreign goods?

The scene was silent, and the sound of machines from the pharmaceutical factory continued to roar. Bottles of penicillin were filled into brown glass bottles and covered with wax sealing caps for packaging.

Two days later, the truck in the glass factory stopped in front of the warehouse, and the driver took the initiative to hand out cigarettes to the guards and apologized for the last incident.
