Qin Xiaosu had a routine phone call with Lin Xiuxuan, reporting that the Japanese army might be carrying out a series of massacres around Saigon. And it is judged that it may be the action of the enemy here to eliminate the future trouble before pouring out of the nest. The Japanese were a hundred uneasy about the French in Indochina. It is also true that the French have been approaching the United States and Britain recently.

Lin Xiuxuan felt that Qin Xiaosu's analysis had some truth, and it was not in line with common sense that thousands of Taiwanese soldiers from Saigon went north, but the more anti-common sense the action, the more likely it was to be related to nuclear bombs. He himself is searching for clues related to the nuclear bomb in Dong Nai Province, but without the support of drones, it has become difficult and he still has no clue. He speculated that perhaps the Japanese nuclear bombs had not yet moved and remained near Saigon. If this is the case, he can only rely on Qin Xiaosu, who is in the south, to carry out further reconnaissance.

This matter is a little difficult for Qin Xiaosu, after all, he is not a professional agent, and it is difficult to get close to reconnoitre, especially when the sky is about to dawn. On the bright side, the Viet Minh guerrillas can provide the puppet Marine Mobile Unit uniforms of the Tran Trong Kim faction. These uniforms may do the trick.

Due to the rapid defection of Shangshu Wu Tingyan to the United States, the Japanese have recently supported a new puppet who is forced to resist the prince. The puppet army of several thousand people under its jurisdiction is called the Marine Police Force. Ostensibly, the force was controlled by Tan Chung Kim, but in reality, it was commanded by Lieutenant General Tsuchihashi, who Sakagaki had brought from Singapore.

At present, the defense area of the Marine Police Mobile Unit coincides with the Japanese mobilization area, that is, it has the opportunity to get close to reconnaissance (including eavesdropping on low-power walkie-talkies) by taking advantage of that level.

But the danger is still great, because the Japanese have reached a state where they are all soldiers. In recent days, there have been a lot of frictions between the Japanese army and Ngo Dinh Diem, the puppet army of the Nguyen Dynasty, and the French army. So there are still a lot of uncertainties in the river controlled by the Japanese in broad daylight. In addition, there are technical difficulties, as the probability of finding a nuclear bomb with a single Geiger counter is close to zero, and even if you board the cargo ship loaded with the nuclear bomb, you may not be able to emit a weak source of radiation. Clues must be found through some indirect means, but intelligence analysis is Qin Xiaosu's strength. Therefore, even if there are many difficulties, Qin Xiaosu must still take on this responsibility, and he asked Lin Xiuxuan through the radio to ask for his life, asking to enter the delta river network to find out.

After Lin Xiuxuan agreed, he and four other guerrillas, dressed in marine police uniforms, hats, and each carrying an old French rifle, rowed a small boat into the lower Mekong River basin. The boat was filled with bananas, which he used to cover his equipment.

He brought with him a sweeping radio station that could listen to the surrounding communications. The Japanese walkie-talkie needs to be monitored at close range, and perhaps some information can be obtained. The Viet Minh guerrillas only regarded the technical equipment provided by the Americans and did not ask much, and of course the Japanese did not necessarily know how to rub sand in their eyes, and if necessary, they could directly throw the radio into the water. The radiation detector is in a backpack, and most of the time, this counter will detect trace amounts of radiation, but it is close to the background radiation level in nature. The decay radiation of the nuclear charge itself is weak. Although the audio cycle fluctuates as the position of the boat changes, it is difficult to find the direction with this slight change. And the change in sound is likely to be caused by the interference caused by nearby mineral veins.

As the sky grew brighter, ships carrying Japanese troops passed by from time to time. If the Japanese soldiers on the ship shot at them, there was no way to dodge, but fortunately they didn't pay much attention to the approaching of the small wooden boat. The Japanese soldiers on the boat were condescending, looking coldly at the marine police boat below, some of them seemed slightly vigilant, and some of them were careless.

The "Vietnamese flag" with a red bar on a yellow background on the stern of this small boat was the only barrier to avoid Japanese shooting, which was a useful information that Qin Xiaosu heard from the radio. In the early hours of the morning, Lieutenant General Tsuchihashi issued an order that from today, the Japanese army could fire at all suspicious targets that continued to fly the colonial flag (similar to the Vietnamese flag, except for the French tricolor in the upper left corner), but the new government's "Vietnamese flag" was not among them.

From time to time, Japanese soldiers on board would greet them. Qin Xiaosu has been following the troops recently, and he has already tanned a lot, so he dares to raise his head and look at those Japanese soldiers. The Japanese soldier even said that he wanted bananas, and after he threw a few strings, there were even Japanese soldiers who threw down cigarettes, which was regarded as an exchange.

Infiltrating the enemy's control of the water network was a fluke, but nothing was gained, no suspicious ships were seen, and no valuable communications were heard. It must be admitted that lately the enemy has carefully controlled radio communications, and it is difficult to find useful information from the communications of junior officers. Sometimes, the enemy will even spread misleading false information through the radio, intentionally or unintentionally. Qin Xiaosu has already heard several times that the communication that "important materials" will go ashore in Haiphong, if it is not for 419 going north, it happens to pass near Haiphong, and reconnaissance has been carried out, and no "important materials" have been found These fake news will obviously interfere with judgment. The enemy did not know the exact existence of SCP-419, but they began to spread disinformation in a very passive state, which is indeed a very alarming situation.

Throughout the morning, they crossed several rivers and did not find a single large boat of more than 1,000 tons. The Japanese requisitioned all of Saigon's motorized boats (even non-motorized sailboats) to transport troops, which covered the river. However, there were no large balloons or other large equipment piled up on the deck. According to the SCP-419 report, the suspicious ships were carrying what appeared to be the army's anti-chemical warfare units, but unfortunately they were never found.

It wasn't until noon that a seemingly useless communication was noticed by Qin Xiaosu.

This was a direct order from the Saigon garrison to a squad below the 16th detachment, which ordered the squad to stop the "established plan" of the French barracks, immediately collect the sappers and * in it, rush to the tributaries of the Saigon River, blow up Bridge No. 17, and then "finish it all" with the French infantry.

This seemingly ordinary order can easily be drowned in a sea of radio communications. Because there is not half a word in the communication that has anything to do with nuclear bombs.

But Qin Xiaosu was a master of intelligence analysis after all, and he quickly realized that it was actually very unusual for Major General Nasu of the garrison to directly issue orders to a small team.

Obviously, there was a lack of engineers in the Japanese Marine Corps, and they didn't really need engineers when they shipped north.

Suddenly, they need to requisition French sappers, and the target is a bridge, and the fragmented information is put together to make some sense.

He quickly checked the map. Discover the bridge, located on an inconspicuous tributary of the Mekong River. Neither the Viet Minh nor Zhou Youfu's team was there. Apparently the destruction of the bridge, which has nothing to do with normal military operations.

The guerrillas around him, no one knew about the bridge, but fortunately, the last drone reconnaissance of 419 a few days ago happened to include the bridge. So he called Lin Xiuxuan again and learned the height of the bridge, so he deduced a conclusion. Perhaps it was because the bridge was too low to fit a slightly larger ship, especially if the ship had some special device installed on top. Judging by the schedule of the enemy's bombing of the bridge, it is likely that a larger ship will pass there at night. Major General Nasu probably didn't know the essence of the mission, so he didn't have a sense of secrecy.

Of course, this conclusion was still speculation, and the only thing he could do now was to get there and see for himself.

When they arrived from the fork in the creek, a large boat had already stopped there, apparently waiting for some time. Not far away, on a steel girder bridge, some French soldiers with safety ropes are installing on the piers*. They apparently did not know that the time they completed their mission would be the day the Japanese sent them on their way.

Qin Xiaosu used a telescope to carefully observe the ship several times, confirming that it was not any of the four suspicious ships photographed by the drone, but it was obviously a special-purpose ship. Looking at the hull, it looks like an inland gunboat, because the superstructure has changed so much that it is impossible to identify the original ship type. All the artillery in front and behind were dismantled.

It can be seen that a huge bracket is installed on the superstructure in the center of the hull, and sparks are flying on the bracket, and there are workers doing electric welding, which shows that this device is not finished, and it is in a hurry to get on the road. It seems that this bracket is not dead, there is a hydraulic device underneath, and it seems to have a lifting function.

Qin Xiaosu suddenly gasped, maybe it was an initiating platform that could be raised temporarily?

Of course, there is a basis for making such speculations. * The explosion height will affect the power dispersion, especially the power of the Japanese primary nuclear bomb is only 10,000 tons or 20,000 tons, and it is very possible that they are trying to make some fame in this kind of detail.

From another point of view, apart from being a nuclear explosion platform, Qin Xiaosu couldn't see the point of installing such a huge shelf. In fact, it was the extreme height of this shelf that caused the ship to be unable to pass through this section of the river. In the end, it was necessary to blow up a strategic bridge for its passage.

However, Qin Xiaosu still couldn't fully convince himself. Nuclear bombs were transported directly in the river network, making it difficult to get close to the dense areas of the Chinese army, and Zhou's tank troops usually avoided the rivers. He hadn't figured this out yet.

He immediately started a communication with Lin Xiuxuan and reported the discovery. Now that the task force is scattered around, looking for possible threats, it is clear that the time has come to collect them. After completing the communication, Qin Xiaosu's boat circled around other small rivers and waited 2 kilometers upstream of the river. At 5 p.m., with an explosion, Bridge 17 was blown off in the middle. Then two patrol boats with searchlights passed under the broken bridge, and after waiting for a while, the river gunboat "Anzhai" slowly passed.

The addition of such a steel bracket of several hundred tons to the weak hull made it easier for the river gunboat, which was not in good condition, to capsize, and the ship could only maintain a speed of five or six knots, avoiding any slightly drastic maneuvers that could lead to capsizing.

Now the Special Group is faced with the question of further confirmation, since it cannot be ruled out that this is just a cover operation by the enemy. And the ships with the detection balloons have not been accounted for so far.
