"Reporting to the command cabin, the pressure in the pipeline is stable, no leaks were found. Forecasts can increase pressure by a further 10%. "Good news came from the intercom again.

"Hey, I'm dying, political commissar, you're keeping an eye on me here, I'll go to the *cabin to watch them wipe *."

Cheng Dayang couldn't wait and left the command cabin.

Delayed until 8 p.m., the Japanese fleet, which had been hovering off the coast of Lingang, finally set sail, making simple contact through a series of rapid light signals, and then lifting anchor. The formation of Yuyun takes the lead, Izumo follows, behind the Qifeng Palace, and Nagara is in the formation of the east.

As the tide rose, the stranded anti-smuggling boat was finally able to move again. Watching the enemy fleet disappear from afar, they cautiously turned to the opposite place, and had to get back to Tanhu Island before dawn, and then they had to bury the boat.

In the middle of the night, 419 completed the first stage of testing, finally completely unplugged the external power supply, reversed and left the port, and the submarine prepared for the second stage of the heavy load test, and the whole test process, unhurriedly, completely ignoring that the target was fleeing. Of course, the next stage of the test is, in principle, still the measurement of the pipe pressure and the value of harmful radiation. The boatswain sat on the Meteor, following closely behind, just in case, but overall, the bulk carrier was coming to the end of its mission.

Soon, the 419 power increased to 25% and continued to pick up speed, and the Meteor could no longer keep up. The ballast tanks of 419 began to enter the water, slowly diving into the water, maintaining periscope depth. Then, the high-frequency bathymetric sonar was turned on to make a second survey of the nearby seabed topography, partly to improve the seabed topography data of Hangzhou Bay, and partly to find a suitable place for the Meteor to sink itself.

At 4 o'clock in the morning, the No. 419 nuclear submarine finally resumed its long-lost speed of 20 knots, dived to the vicinity of Yangshan Island at the exit of Hangzhou Bay, and listened to the whereabouts of the Izumo with the help of bow sonar and underwater acoustic channels. Later, he detected the movement of the medium-speed thruster driving close to the sea, and it was impossible to tell whether it was the enemy patrol ship or Lin Xiuxuan who had returned, and from the track, it seemed to be Lin's ship. Cheng Dayang ignored him and swerved to the other side to test high-speed turns.

Lin Xiuxuan stood at the bow of the boat facing the sea breeze, and unconsciously, staggered with 419 below. At dawn, when we finally arrived near Tanhu Island, 419 was no longer there, only the Meteor was alone on the sea.

At the bow of the Meteor, the political commissar was waving to them, and the small boat leaned over and connected the political commissar and other personnel in charge of the sunken ship on the Meteor to the anti-smuggling boat.

Testing of 419 went smoothly, and the need for the Meteor's existence was gone.

"The sea valve has been opened, and it will sink soon."

The commissar said standing on the foredeck of the anti-smuggling boat.

"Lao Pan, can you still catch it?" The boatswain seemed to have some affection for the wrecked ship and asked about it.

"We looked at the topography of the seabed, which is very flat and sits at a small slope. If necessary, divers can go down and install airbag equipment, which can be easily salvaged, but the main engine may be scrapped. ”

As he spoke, the ship's waterline dropped considerably, and soon it was back to the porthole below deck. Eventually, the mast disappeared into the sea, and Lin noticed that the French flag that had been stepped on by the sewing machine had not yet been confiscated and was fluttering on the sloping mast.

"I forgot to take it back, well, to commemorate the fall of France for a year...... Zero two months. Lin Xiuxuan said and took off his hat.

Standing on the crowded foredeck, watching the sinking of this great cargo ship, the boatswain even moved his emotions and shed tears, not for France, of course, but for the ship.

200 meters behind the anti-smuggling boat, a huge wave suddenly surged, and a huge nuclear submarine rushed out of the water at an elevation angle of nearly 30 degrees, and the waves she stirred up violently shook the small anti-smuggling boat not far away.

As soon as the submarine stabilized, Cheng Dayang appeared on the enclosure, and soon his voice also appeared on the walkie-talkie channel.

"Don't grind, the enemy ships are leaving quickly. We need to speed up. ”

"How's the submarine testing?"

The commissar asked.

"At one point, it reached a 7 success rate, but unfortunately it was too small here to test the speed. In short, the situation is not bad, as long as you can catch up, you will definitely be able to destroy Izumo. ”

The anti-smuggling boat set sail and sailed to Tanhu Island, where a deep pit had been dug in the beach, and there was a set of small ditches that could be driven directly into the pit, and the current tide was just enough to drive into the ditch, and then the ship could be buried.

The crowd got out of the boat at the shallow water. Xu Chong operated the anti-smuggling boat into a deep pit. Two pumps on the shore began to pump water, and the boat gradually fell to the bottom of the pit, and the people filled the sand with shovels in an attempt to bury it. At the same time, the final evacuation of the remaining facilities on the island began, primarily the communications / reconnaissance stations on top.

419 re-landed on the shore reef, Cheng Dayang anxiously waited for the people on the shore to get on the boat, he calculated from time to time on the chart the current possible position of the cloud fleet, these few hours, they had left nearly 100 nautical miles, with his speed advantage of about 6 to 8 knots, he had to wait until this evening to keep up, maybe tomorrow early morning to occupy the lead, in the afternoon to attack.

Once Izumo is sunk, the next task is relatively simple, one is to go to the area where the Kasuga Maru sank that day, to detect, first to determine its current underwater position, and then have to ask Team Leader Lin to go ashore again, this time to find a way to get diving equipment, so as to dive into the Japanese ship and find the machine that controls the crossing. The second task in parallel was to continue to wait until December 7, when Japan attacked the US Pacific Fleet, so that the enemy's defeat was doomed. If the above two go well, then they can return. Of course, the subsequent actions only exist in everyone's imagination, not even a plan on paper, Lin Xiuxuan is in the stage of danger and precariousness in the Mahler shipyard, who still has the heart to think about the future?

When the sky is dark, the last hidden work on the island is complete, and if the enemy lands on the island, as long as they don't dig three feet into the ground, they should not find any clues. Of course, if needed, 419 can quickly resume its original deployment when it returns to the island. The landers returned to the submarine, and now it was finally Cheng Dayang's turn to regain control of the situation, and he had been waiting for a month for this moment.

The submarine unhooked the cable and quietly withdrew from the harbor, and then the ballast tanks flooded, and the entire boat was submerged, leaving only a periscope. The navigator Tao Jianjian began to formulate the quickest pursuit route, while Shu Ping squatted in the rear cabin and continued to inspect the various pipes that were as dense as spider webs over and over again. Judging from the pressure figures, there is no sign of leakage for the time being, but he still has to go back and forth a few times to be reassured.

In the command cabin, Cheng Dayang was holding a periscope and was observing the situation around the route left and right. Sonar detection, it is difficult to detect unpowered fishing boats nearby, he has to keep an eye on it. Of course, there are also searchlights on the commanding heights of Yangshan, of course, these threats are still weak, but because they have to be close to the coast, this will inevitably increase the difficulty of navigation, due to the change of seabed topography, the 419 database only has topographic data for the next few decades. Of course, if sufficient high-frequency depth detection is carried out, the terrain can still be mapped in real time, but the worst thing is that Cheng Dayang also needs speed, which makes him have to rely on some future geographic information, which is similar to the situation of Shu Ping operating a meteor through a sandbar. Because tactically requires the submarine to have a period of time to surface (retract and release the drone), he must do it in the middle of the strip of water, that is, where the anti-submarine aircraft on both sides cannot reach, so the time requirements are more demanding.

"Guantong Department, can you continue to catch Izumo's traces?"

"The water was too shallow, and the broadside sonar was too effective to spot Izumo. However, the Yangtze River estuary was found in the 4,500-ton tanker of the diesel engine of the American Standard Company. Guan Tongchang said.

"Okay, that's all for sure. Look for the cloud again. ”

Chu Aiyun began to determine the approximate location and distance of those oil tankers, and the other parts were just for practice. It has not been found in the periscope yet, and it is visible at a distance. A while ago, when he was idle at the Mahler shipyard, he hoisted a recording device into the Huangpu River and recorded the sound characteristics of various ships, which can of course make up for the gap in the 419 voiceprint database for the records of old ships of this era, of course, the first thing is the engine characteristics of Japan, the United States and Britain warships, followed by these cargo ships, for the superior strength of 419, these data are still quite important, for the identification of targets have a considerable effect, in addition to recording the matching data of the speed of the main engine and the speed, It is useful for the measurement of moving targets with passive sonar under water.

"Deputy Chief, where did Lin Xiuxuan go, why did he sail together and disappear."

"Just now in the medical room, a few wounded soldiers in his group need to be treated, and now he said that he went back to sleep."

"Hehe, it's okay to go, these days I always watch him steal chickens and dogs from the drone, and it's a worry to watch." Cheng Dayang shook his head and said, now that he has taken over the situation, it's time to show his hand.

"Team Leader Lin said that he wants to nourish his spirits, and he will see you sink out of the cloud later."

"Why are you also calling the team leader?"

"I mean, Director Lin, he said it."

"What's the matter with Shu Ping, why hasn't he gone to sleep yet?"

"The chief mechanic said that he has not slept for the past 40 hours, and he has to monitor the situation throughout the process."

At the same time, Lin Xiuxuan sat on the bed alone, thinking about the next stage of action. He didn't have Cheng Dayang's feeling of being reborn. Although the main task was completed, and the additional task of saving Ma Qiang was also passed, all the footholds in Shanghai were lost by the Japanese, and Shu Ping could have been asked to use the equipment of the Mahler shipyard to make a pressure-resistant diving bell for the next stage of underwater diving, but now that it is in the soup, then it can only be found by divers, and there is no gas mixture in hand, which is also a problem.

In this era, helium is only produced in the United States, and China's technology is backward and there is no demand at all, so I don't know where to get it? The underground party deliberately left a contact method, but he was reluctant to go to Hu Yuexin, he felt that he was pretending to be a ghost in front of his predecessors, and he was very unconfident. Before he knew it, he fell headlong and fell asleep.
