In the night, a crescent moon crept over the lonely Project 419 submarine.

The fleet led by the Long Xiang staggered past the No. 419 submarine at a distance, and gradually moved away. The radar of the 419 has always tracked the enemy ship completely, and the anti-aircraft search radar observed that two carrier-based aircraft were unable to complete the night landing, and finally flew westward, and the listening equipment even intercepted some of the conversations between the aircraft carrier and the carrier-based aircraft in the communication channel, and determined that they would land at Longhua Airport.

As the submarine got closer and closer to the shore, the lookout could already see the sparkling light flickering on the shore. These dim, sluggish lights barely move, as if small fishing boats were catching squid with their lights hung. This is a stark departure from Cheng's experience of sailing along the coast, when it was clear that Chinese fishermen in those days lacked mechanically powered boats to go too far into the ocean. Of course, it is impossible for Hangzhou Bay to be free of Japanese naval vessels, so the radar has been vigilantly searching the surroundings, closely tracking the movements of hundreds of small fishing boats, and strictly guarding against large ships mixed in them. But there was never a target that was too big or too fast. Lin Xiuxuan's absurd plan is still feasible for the time being.

"Reactor control room, how's it going?" Cheng asked, asking the same question to the engineer every 30 minutes.

"The steam leakage fault has been preliminarily ruled out, the reactor is currently stable, the cooling pump can cope with the decay heat, and no radioactive leakage has been detected for the time being." The electromechanical chief's answer was exactly the same as it had been 30 minutes earlier.

"When can I restart the reactor?"

"I don't know yet, fortunately, the damage is all the minor equipment around, I will make a list of spare parts, if there are a few machines, I can do it myself."

The captain was silent, he knew that things were really tricky, and that in this day and age it might be possible to find diesel, but where to find parts for submarines; The mechatronics still wants a machine tool? He couldn't even think about it.

According to Cheng Dayang's intentions, the shift leader has been preparing to take advantage of the night to enter Hangzhou Bay and quietly enter the bay, the navigation radar has already clearly drawn the nearby islands, and compared them with the database map, the Hangzhou Bay Bridge from Jiaxing to Cixi, and the Donghai Bridge connecting Yangshan Island do not exist, and the actual conditions and records of some tidal flats have also changed to some extent.

"9 km on the port side with a large number of low-speed boats. It is somewhat difficult to cross the Shengsi Islands, and they will most likely see us under the moon. The navigator reported.

"Modify the course to pass between Daishan Island and Qushan Island, don't pay too much attention to low-speed boats, just keep an eye out for larger motorized boats."

"Understood. A searchlight was observed on the south side of Daishan, and we walked from the north? ”

"Okay, go from the north."

Obviously, even if it is seen by a fishing boat, there will be no major consequences, and the fishermen will probably think that the boat is Japanese; Only high-speed boats may be Japanese patrol vessels and must be dealt with carefully.

"Azimuth 095,11 km, low-speed boats were spotted."

"It's like a river gunboat with a shallow draft."

From the radar, a bunch of small fishing boats were avoiding the boat, which was traveling at about 9 knots. Soon the observers on the hull saw the ship glowing with a searchlight about 10 kilometers away from the sea, and the people in the command cabin were silent, apparently it was a small gunboat that was not too large. In a few moments, the rumbling of cannon came from the other side of the bay, and the ship actually opened fire on the shore.

"Director, it looks like the Japanese don't have full control over the perimeter of Shanghai?" Cheng Dayang said to Lin Xiuxuan.

"Maybe it's the Loyal National Salvation Army west of Shaoxing that is active? Or is it our armed working group of the Haibei Working Committee? ”

"Director, do you have an accurate one?"

"Then you need to ask? Of course not. ”

At 1 o'clock in the morning on July 2, 1941, the submarine was very close to the end of the route, Tanhu Island.

The navigation equipment easily found the hidden harbor indicated by Lin Xiuxuan, and at the same time, Cheng Dayang turned on the high-frequency sonar detector under the keel to map the seabed topography, although the database had hydrographic data, but he always felt that the data in the database from 1960 was too outdated, or to be precise, "too advanced", and not suitable as a basis.

During the exploration, the Japanese Atami-class gunboat fired more than 20 guns in the direction of Zhejiang, objectively driving away the fishing boats on the south bank for No. 419, and then the gunboat sailed in the direction of Ningbo, and the harbor returned to tranquility. Search radar surveys of the sea surface indicate that most of the fishing boats on both sides of the strait are between 5 and 8 meters in size and operate no more than 3 kilometers from the coast, perhaps at this time and age, without having to go deep into the bay to catch fish, or simply because it is typhoon season.

Tanhu Island is located far from both sides of Hangzhou Bay, and it seems that fishermen on both sides will not easily approach it.

Under the dual effect of navigation radar and sonar, the submarine finally sailed into a small harbor, and there were no lights on the island, which may be an uninhabited island.

It took a lot of time for the submarine to finally get close to the cliff on the north side, and after Cheng Dayang studied the nearby terrain, he decided not to anchor, but to increase the depth of the dive, and directly sat the keel on the hard and flat rocky seabed, which increased the trouble of mooring, but reduced the part of the submarine that was exposed to the water.

It took an hour for the submarine to gradually stabilize, and finally the front and rear decks were completely submerged in the water, leaving only a part of the hull on the water, in addition to increasing concealment, the additional benefit is to reduce the windward side. Navy flags and national flags or something, of course, have to be put away. The white word 419 can only be erased later. After completing all this, Cheng Dayang sent people to take a rubber boat with a mooring line ashore and fixed the two ropes on the reef on the shore.

The first landing team consisted of 2 rubber boats, composed of a mixture of the surface team of No. 419 and Lin Xiuxuan's intelligence officers, the surface team only had some mediocre automatic rifles, which was far worse than the equipment of the intelligence group, Lin Xiuxuan's people were equipped with thermal night vision equipment, and they could perform tasks without lighting at night.

Before dawn, these people had searched the island twice, and found not a single person, except for a few broken brick houses that had been uninhabited for a long time.

After dawn, Cheng Dayang can finally stand on the shell and watch the entire small harbor, although the island is not big, but this small bay can just hide the submarine, and can also shelter from the wind and waves.

The island was lush and overgrown with towering trees, and it seemed that some branches could be sawn to cover the shell, and he observed that after the tide receded, a large part of the submarine shell would still be exposed. According to Cheng Dayang's vision, tree branches can be used to conceal the shell from above, not only to prevent fishermen, but also to prevent passing aircraft from spotting.

The patrol set up an observation post on the commanding heights, and even if it was officially rooted on this island, of course, it could not last long, after all, this island is only 24 kilometers from the coast of Fengxian and only 44 kilometers from Cixi. Since there are houses on the island, it is natural that no one will ever be able to reach them.

After settling the submarine, the crew cleaned up the dilapidated houses on the island and used them as temporary wards, where the wounded who had suffered from trauma and blood loss needed fresh air and sun.

A day earlier, the submarine had been strafed by Japanese seaplanes, and a total of four people had been injured, but there was no major problem, and the medical facilities on the submarine were sufficient to deal with these problems.

This afternoon. Cheng Dayang had a closed-door meeting with Lin Xiuxuan, and the political commissar resigned and did not attend, he said that he would go to the mountain to take care of the wounded, and made it clear in advance that he would only appear when the two sides were deadlocked, and would not participate after the general discussion.

The two smoked 50 cigarettes in six hours, and in the smoky officers' conference room, they discussed the full details of the landing, including personnel arrangements and what to carry.

No one knew what the coastal dwellers wore in this year, and it was impossible to have suitable clothing on the submarine, so they decided to go ashore in training uniforms and find a way to change them.

The number of people who went ashore was tentatively set at three. Of course, Lin Xiuxuan himself has to go, and the other is the boatswain Lu Dacheng, he is a native of Jinshan, although there is a gap of more than 70 years in time and space, but the local accent should be about the same; The last candidate is Ma Qiang, a member of Lin Xiuxuan's intelligence group, the young man is tall and big, shooting, fighting, diving, capturing everything, and taking it with you can be taken care of.

The items carried include a knapsack 20-watt short-wave digital radio station with six whip antennas; A V/U-band walkie-talkie is handheld, so that you can maintain voice contact with the submarine and receive drone intelligence. 3 pistols, a flare gun, a night vision device, a camera, and some individual rations. Then, they studied in detail the main communication channels, backup channels, and adaptive frequency hopping bands under special circumstances, and determined that the call signs of the landing team and the submarine were "weasel" and "black dragon" respectively. Then the meaning of the use of different color flares was agreed; When and how drones provide relay communications and other support, and so on. Of course, no matter how lively these discussions are, they cannot solve a serious problem, that is, there is no currency of this era. This major flaw seems to show that Lin Xiuxuan and his superiors actually have very limited understanding of this mission, although they are generally aware of the Japanese conspiracy, but they are not ready to face a real crossing. Of course, who would have thought that the Japanese crossing would be in such a violent way, Kasuga Maru even put himself in it, and No. 419 now needed to be repaired ashore in 1941.
