At noon, an observation post on a nearby water tower spotted a Dodge 10-wheeler truck approaching, but there was no tracking behind it, and after a while, the driver honked his horn at the door, waiting to open the door.

Lu Dacheng took two team members disguised as stevedores to go out to support the propylene that should deliver canned food, while the others hid on the second floor of the warehouse and continued to watch the drone video through a portable computer. The new situation is that the headquarters of the 13th Army Corps and the commander of the Navy's Third Fleet have added sentry posts and even tanks, and it seems that the enemy is also facing a great enemy. From the drone's field of vision, it can be seen that the battleship Izumo is parked on the edge of the dock of the Mahler shipyard, and the crew is scrubbing the first class, which seems to be relatively relaxed, and from all indications, it seems that the sailors are going to go ashore on vacation, which is a good sign, indicating that the enemy has not noticed any changes in the shipyard. The sister ship Iwate did not appear, and it may have returned to Yokosuka.

However, it is still impossible to find the location where Ma Qiang is being held through drone volley surveillance alone. The daylight of the day passed in the waiting for the intersection, and the progress was very limited.

In the evening, 419 intercepted a telegram sent to the Ministry of the Navy by the command of the Third Fleet, which asked the Ministry of the Navy to put pressure on the Army not to interfere in the work of the Navy.

The telegram still doesn't go into much specifics, although it has something to do with Ma Qiang's affair no matter how you look at it.

In the evening, the second UAV took off, taking over the surveillance mission, it took advantage of the night to the surrounding airports, carried out a thorough survey, found that Longhua Airport had an extra transport plane, and the rest of the surrounding airports did not find any changes, and now it is roughly certain that if the enemy needs to transport prisoners to Japan, it will take off from Jiangwan Airport.

Lin asked Lu Qingshan to judge the possible route that the enemy would take once the enemy escorted the prisoners from Hongkou to Longhua, and made a corresponding plan. Since it is necessary to detour the concession from the west to Longhua from the Hongkou area, there are not many roads, and it is easy to guess that there will be a large open area on the way to carry out an ambush. The only problem is intelligence, if the enemy uses wired telegraph or telephone to communicate, 419 is likely to be unable to intercept the corresponding information, and there is no good strategy for the time being, so the drone can only expand the monitoring range, and from time to time take a look at the transport plane parked on the side of the runway at Jiangwan Airport, whether it is close to the runway to prepare for takeoff.

In the wee hours of the morning, with the exception of one member of the special team left behind by the boatswain, the others boarded the motorboat and headed for the shipyard, a few kilometres to the north. The enemy's warships were scattered on both sides of the Huangpu River, and from time to time there were searchlights on board to scan the river, but the Japanese warships paid more attention to the few British and American light cruisers at the berths in the concession, and did not pay much attention to the tax speedboats patrolling the river.

The group successfully docked and finally arrived at the shipyard, and one person drove the motorboat back to the berth near the warehouse to avoid being seen by the shipyard workers during the day and becoming suspicious.

Lin arranged for them to go to the factory to have a look first, and then go to the dormitory to settle down, first hide the radio and antenna, and then arrange for the secret post to be on duty. The drone can see that the Japanese youth patrol with flashlights outside the wall passes outside the factory every 5 hours, and through the thermal imager, you can also see that inside the wall, Lin and his party are sneakily walking back and forth around the dormitory and the factory, as if they are making final preparations for the start of construction.

In the morning, Lin Xiuxuan introduced Zhang Guangcai to meet with Shu Ping's following technicians, Manager Zhang was not very suspicious, and everyone met and shook hands one by one, and then politely said that yesterday had found a carpenter to repair the bed, broken doors, windows, and roofs have also been repaired. Zhang Guangcai was originally in charge of production, but there was nothing to produce recently, so he was in charge of everything.

Lin Xiuxuan told him that these people are apprentices from the countryside, who come to practice their crafts, they don't need to register, they don't pay their wages, and they don't have to ask in the factory.

Manager Zhang nodded yes again and again, he didn't think about it carefully, the average age of these people he saw was over 30, and they were all white and clean, how could they be apprentices recruited from the countryside.

In the morning, Shu Ping first installed ventilation equipment in the workshop, then covered the doors and windows, and began to arrange manual trial production. Start with a simple O-ring, which is a sealing device outside the main shield. When 419 encountered a crossing, some pressure components were damaged, as well as some pressure-resistant circuits and flange connections, and the surface was intact but could not be detected, and additional rigid supports had to be tightened and added to increase safety redundancy in case the reactor was restarted. These are the easiest to produce, and the main requirement is precision rather than strength. High-precision CNC machines can be completed in a few minutes by cutting. However, the accuracy of the old-fashioned machine tool depends more on the technology, and as soon as you get started, you will find that the machine is not suitable, and several pieces are processed in a row, but they are not up to standard. According to the accuracy requirements of Shuping, the defective rate is 100%.

Shu Ping was not in a hurry, because this situation was completely within his expectations, and he never promised anyone anything by patting his chest, this was his style of life. Anyway, some of them are material training, and he personally led his subordinates to try to produce the secondary circuit exhaust system, which is part of the condensation pipeline and does not require high pressure. He wanted to familiarize himself with the equipment and see how accurate these German Express machines could achieve.

Lin Xiuxuan had seen Shu Ping working on 419, not only was he methodical, he was simply immovable, and he was not the kind of person who was in a hurry at all. Lin didn't have the heart to watch them continue to produce defective products, so he personally arranged for the special team to be on duty in turns, and then left the workshop in the west area.

He went to the vicinity of the slipway to inquire, Brother Ma didn't come today, and he didn't ask for leave, I don't know why, he was anxious for information, but Mr. Hu seemed to be ineffective. For the time being, he can only rely on himself, he said hello to Manager Zhang, and went outside the factory, wanting to personally go to the headquarters of the Marine Corps on Sichuan Road to find out the news, and wanted to take Lu Qingshan, who can speak Japanese, but someone must keep an eye on the drone and make an ambush plan, so he can only go alone.

I hired a car to North Sichuan Road, mixed in the crowd all the way, eavesdropped on all kinds of conversations, and at the Hirano barbecue restaurant, I heard Japanese civilians drinking in Japan talking about the battle at Waibaidu Bridge two days ago, and I heard that four Japanese had been killed and three seriously injured. A group of Japanese lamented that since 813, it is not surprising that the imperial army has been in a scene of one as ten, and they have never seen such a powerful Chinese soldier. A puffed Japanese said that he had to be publicly beheaded so that the Chinese would know what would happen to his majesty's soldiers.

Lin went all the way to the Marine Corps headquarters, the last time he passed by, there was only a tank and 2 sentries parked at the door, and today there are about half a squad of Japanese soldiers on guard near the gate, with bayonets on their guns, and machine guns are set up, and there are 2 more armored vehicles at the door.

The Japanese sailors saw that there were Chinese looking inside, and immediately drove them away with guns, Lin Xiuxuan could not stay at the door for too long, he really wanted to turn into a mosquito and fly in, but unfortunately now the precautions here are strict, and the water cannot be splashed.

If we look at all the military strongholds of the Japanese army in Shanghai, the army headquarters, the Marine Corps headquarters, and the gendarmerie are the last places that may be held against Ma Qiang, these places are very heavily guarded, and they all have their own prisons, and the rest of the places are too small to hold facilities for interrogating felons. Judging from Ma Qiang's current gunshot wounds, it is necessary to add the respective hospitals of the navy and army.

He sneaked to the headquarters of the 13th Army stationed in Shanghai, defended more tightly, and directly blocked the gate with Type 95 tanks, and found out any news at all. I went to the naval hospital on Jiangwan Road again, and found that there were also soldiers guarding the door, but there was no strong headquarters, and it seemed that there were Japanese military uniforms that could be mixed in, and the documents were not checked, but unfortunately he was not at the end of the day.

It's a ghost, why are the army and navy units and hospitals on guard together, where is Ma Qiang?

Lin didn't dare to go to the gate of the gendarmerie, for fear of causing trouble, so he could only go back to the factory first. As soon as I arrived at the door, I bumped into Brother Ma who came in a hurry. The two didn't enter the factory, but first went to the herbal tea shop across the street. Brother Ma didn't go to work today, just waiting for the news above. In the afternoon, there was finally some news, so I rushed to find Lin.

Hu Yuexin inquired through his connections that Ma Qiang might be in the Japanese gendarmerie at this moment, because the gendarmerie was about to escort important prisoners to Japan, but the names of the prisoners were not heard, and it may be that the enemy deliberately omitted them, or it may be that the local intelligence units did not torture them. Available intelligence indicates that the enemy will escort important prisoners to Japan via Yantai through the Japanese Navy-controlled base (Jiangwan Airport).

Judging from the degree of attention paid by the enemy, it can almost be concluded that it is Ma Qiang. However, Mr. Hu could not figure out why the Japanese intelligence agencies gave up so quickly, it is said that Ma Qiang was arrested only 40 hours ago, and the Japanese have a complete intelligence system in Shanghai, and there is no shortage of manpower and methods; In the old Japanese army's concept, it was a very shameless thing to throw a difficult problem to the superiors. And Hu Yuexin has never encountered a precedent for sending Chinese prisoners to Japan for investigation.

The specific escort time has not yet been decided, and the day after tomorrow may be the day after tomorrow, Hu Yuexin told Lin Xiuxuan through Ma Xiaodi, or that sentence, it is best to break the idea of rescue, because it is impossible.
