These reconnaissance photographs were quickly sent to the hands of the aviation staff officers, who carefully identified the objects in the photographs, described in detail the various facilities in the port, and recorded the locations of the oil depots, ammunition depots, barracks, airfields, berths, and other key departments one by one, but there was one object that they did not know what it was.

That strange thing was a kind of white spots, and at first the staff officers thought that these were defects caused by the development of the photos, but these white spots were on each picture, and they were arranged quite regularly, which aroused the attention of the staff officers, and they immediately reported the situation to Sun Xiaohu.

If he couldn't figure out all the settings of the other side's port, he could have failed the sneak attack, so he sent a naval commando team to find out.

A Sahr cruiser, the Altri, was slowly entering the port of Tunis, smoking a lot, and they were part of the Maritime Patrol that had been tasked with searching the seas for possible transit ships of the Chinese Empire, or warships that the Allies had come out to cruise.

During this cruise, the Alteri gained a good harvest, and actually found a thousand-ton merchant ship of the Chinese Empire, and it was a civilian one. The Alteri encountered it two hundred nautical miles from the port, and the merchant ship refused to stop the ship and flee for inspection, and in the end the Alteri had to sink the merchant ship, and only three members of the crew were rescued.

At the end of the patrol, the Altri returned to the port of Tunis, and the three rescued crew members were naturally brought back, at this time with their arms tied and escorted off the ship by sailors.

"Hey, Mike, looks like you've got something to gain this time." A guard standing guard on the shore greeted a sailor who had just disembarked, who apparently knew each other.

Mike smiled, "Toms, it's you standing guard today." We were lucky not to encounter the submarines of the Chinese Empire this time. Then he looked at the three Chinese sailors beside him with their heads bowed and explained: "We met a merchant ship of the Chinese Empire, and they didn't stop the ship for inspection, so we sank it and only rescued these three people." ”

Thomas laughed, "Let's send them to the headquarters quickly, if the intelligence department can get any valuable information from them, maybe you can get a reward." ”

Listening to the conversation between the two, the Chinese man walking in the middle had a glint in his eyes, he raised his head slightly, peeked at the situation nearby, and then quickly lowered his head again. If it was in the Southern Ocean Fleet, the person who saw him would definitely be able to recognize that this person was none other than Lin Nan, the captain of the naval commando team of the Southern Ocean Fleet.

At this time, the situation in the Mediterranean region was tense, and all countries were strictly guarding their military ports, and idle people could not get close to this place at all, even the brave special forces were not sure to approach here for reconnaissance, so Lin Nan boldly took risks and designed such a bitter plan.

The merchant ship he was carrying belonged to the Chinese consortium Ocean Trading Company, and at Sun Xiaohu's application, the ship was required to deliver grain directly to a small port in the territory of the Grand Duchy of Sardinia. Lin Nan boarded the ship in the name of a sailor and became a shipside lookout.

This plan was very secret, no one on the whole ship except Lin Nan knew that they were here to send them to death, and the captain trembled along the coast of the western continent, hoping to avoid the Saar warships, but unfortunately the Saar warships were very arrogant in this area, and the patrol range was very large, so they were discovered.

Before setting sail, the captain had been given strict orders not to allow him to surrender to the Sahr Empire, but upon seeing the Saar warship, he immediately ordered him to turn around and flee, but was sunk anyway. Linnan's plan to infiltrate the port of Tunis was extremely crazy, and he was most likely killed by a shell on board, but with loyalty and unwavering faith in his homeland, he did it anyway.

At this time, Lin Nan's heart was indescribably happy, and he boarded the dock of the port of Tunis, even if his task was half completed, now he just needed to figure out what those white spots were, but at this time he didn't dare to look around, once he was noticed by others, he was very likely to be in danger, so he also lowered his head like the other two sailors, and let the Sahr escort them to the headquarters.

According to the procedures stipulated by the military, Lin Nan and the other three were questioned by the intelligence department, they were originally only sailors on a merchant ship, and they did not receive much attention from the Sahr people, and no one paid attention to him after Lin Nan reported that he was a lookout, but the second mate on another ship was closely scrutinized.

The Sahr people wondered why their ship had escaped, so they were a little puzzled, but the second mate insisted that he did not know what secret cargo was on board, only that it was a shipment of food, and that only the captain knew about the specific cargo. The captain is dead without proof.

After some examination, seeing that the second officer did not look like he was lying, they gave up, because they suspected that they were transporting secret weapons for the military, and the three were characterized as prisoners of war. The interrogators finally informed the trio that it was wartime and that they would be detained in the port of Tunis for a few days, and that they would then be transported by ship to a prisoner-of-war camp in the Nantes Empire, where they would not be released until the end of the war.

The three were soon escorted by several soldiers to a makeshift prison for temporary detention, and inside the prison they were sent to separate rooms. Lin Nan walked into the cell, he looked around, this is not a real prison, just a temporary reconstruction of a warehouse, but the walls of the warehouse are thick, and it is also very suitable for a prison.

Lin Nan's room is only about five square meters, very narrow, except for a bed, there is only a toilet in the corner, and there is not even a table for eating, but fortunately, there is a window with thick iron bars installed to breathe.

Lin Nan leaned in front of the window and looked out, this place was facing the dock, looking at the busy sailors back and forth, Lin Nan couldn't help but smile slightly. When he discovers the origin of those suspicious white spots, the air force will raze the place, and then the Saar sailors will be in trouble.

Lin Nan carefully observed the movement on the dock, the more he observed his brows, the more frowning he became, and after looking at it for a long time, he didn't find anything that was an orderly arrangement of white objects, and he had some unexpected gains in the exploration, it turned out that there were many anti-aircraft guns hidden under some curtains.

These anti-aircraft guns are obviously the latest products of the Sahr, they are specially designed to defend against the Chinese Imperial Air Force, and it seems that these anti-aircraft guns have a caliber of 20 millimeters and a slender barrel, which is not a small threat to bombers flying below 2,000 meters.

"What the hell is that white thing?" Lin Nan muttered to himself in a low voice, although the accidental discovery of a hidden anti-aircraft gun was also a big gain, but his main thing was not yet finished.

At this moment, a steel cable connecting to the ground shook in the wind, attracting Lin Nan's attention. He looked up along the cable, and a smile of surprise immediately appeared on his face. The cables stretched upwards and eventually caught a large white hydrogen balloon in the air.

These balloons, called air-proof balloons, are all very large, relying on hydrogen to rise into the air, held in steel cables, and neatly arranged in the air, filling a large area of the sky near the port.

These balloons in the air appear to be devoid of lethality on the surface, but they are extremely threatening to the aircraft. Once the plane hits the steel cable in high-speed flight, the aircraft will be easily cut into two sections by the steel cable due to its own high speed, which means that the aircraft will be cut by its own high speed.

Finding the target of this mission, Lin Nan breathed a sigh of relief, his mission has been completed, now what he has to think about is how to get out of here and send the intelligence back to the fleet, if he is sent to the prisoner of war camp of the Nantes Empire, then it will be in vain to complete the task by himself.

Lin Nan walked around the house twice seemingly leisurely, carefully observing the surrounding environment, the current situation is a little different from the original assumption, originally he thought that he would be repatriated, but he didn't expect the escape of the merchant ship to make the other party suspicious, but he was imprisoned.

Now if he wants to send the information back, Lin Nan must think of a way to escape from prison. These small cells are all cubicles, the partition walls are also made of blue bricks, and there is no possibility of breaking them, and the entrance is a narrow iron door with a small window on it, and the small ones can't even poke out.

Now all that can be used is the window with iron bars, Lin Nan walked to the window again to take a closer look, this window is one meter square, enough for people to get out, and five thumb-thick iron bars are installed on the window, and the iron bars are built into the wall, and they can't be pry at all.

There are several houses outside the window, and in the distance is the busy port. Looking at the surrounding terrain, Lin Nan had an idea, he had already considered the emergency situation, and had made the necessary preparations beforehand, although before entering the cell, the iron weapons all over his body were searched, and he also had spare equipment.

Seeing that there was no one around, and the prison guards were not patrolling the cell room, Lin Nan quickly put his hand into his mouth and pulled out a thin thread stuck there between his teeth.

The thin thread was very long, and it was connected to the inside of Lin Nan's mouth, and I saw him pinch the thin thread and pull it out little by little. With a burst of retching, a sealed glass bottle was pulled out, and it turned out that the bottle was swallowed by Lin Nan, which escaped inspection.

Taking the glass bottle and looking at it, Lin Nan showed a hint of a smile, he quickly hid the glass bottle under the bed, and waited until it was dark to implement the prison escape plan. For a whole day, Lin Nan lay on the bed with his eyes closed, as if he was sleeping, in fact, he kept pricking up his ears and listening to the movement outside.

Lin Nan silently calculated the time in his heart, and he found that every two hours, a guard would walk around the prison, observing the movements of the prisoners through the small window on the door, and no one would pay attention to them the rest of the time.
