Lu Yuan has been very honest these days, either accompanying Wang Hu to wander around Tianjin City, or staying alone in the basement to tinker with his own designs, but the atmosphere in Tianjin City has become more and more weird. If it weren't for the large number of garrisons in Tianjin, the special high section might have been uprooted, and this would not have made the Japanese army headquarters in North China feel a great threat.

In the past few days, martial law has been imposed by the Japanese army to varying degrees at all the large and small street intersections in Tianjin, and a large number of Japanese troops have driven into the city to conduct a careful investigation of the city with the cooperation of the police. Although the Japanese army is already the master of Tianjin, there are still large and small concessions here, and no matter how strong the Japanese army is, it is impossible for it to be the enemy of so many countries at the same time. Although Lu Yuan's trading firm was also searched, it was the concession patrol and a few plainclothes spies who came.

Lu Yuan's firm naturally has no problems, after all, the firm is in the name of Hogg and Schuchmann, and in any case, both of them are Germans. The Germans' signboards were indeed very useful, but in the following days, when other shops and trading houses on the same street continued to be under scrutiny, Lu Yuan and his family were still calm and leisurely. There were a lot of Japanese soldiers and spies on the streets on the left and right, and Lu Yuan didn't bother to go out, so he hid in the basement all day long and was busy with his own business, only Wang Hu was still taken out by Hogg and Schuchmann in turn.

"Hogg, I might need some explosives, the most powerful one." Lu Yuan's request made Hogg immediately bitter, the Japanese have been investigating very tightly for a while, and those arms dealers in the Tianjin black market have long disappeared, even if they can still contact those guys, explosives will be a difficult thing to get. It's just that Hogg couldn't bear to refuse Lu Yuan, so he had to go out with a bitter face to find someone to inquire about the matter, and it wasn't until it was dark that Hogg, who was full of alcohol, returned to the firm.

"Recently, the Japanese have been checking very closely, not to mention explosives, no one even dares to shoot bullets." Hogg's first words made Lu Yuan stunned, but Hogg's next words made Lu Yuan instantly resurrect. "But I got the news that on the docks, there are several secret warehouses of the Japanese army. I heard that the Japanese army in Tianjin had been secretly transporting arms to bandits in Shanxi, and I wondered if there should be something you want in these secret warehouses. ”

Hogg got the addresses of the secret warehouses of the Japanese army for Lu Yuan, and as for the rest, Lu Yuan needs to handle it himself. "I might have to go out in the evening, and if all goes well, I'll be back tomorrow morning, and if things go wrong, I'll call you guys then." When he finished eating, Lu Yuan routinely explained to Hogg and the two of them, and as for Wang Hu, who was busy fighting fiercely with chicken legs, he had been completely ignored by Lu Yuan.

"I know that what you have to do is dangerous, but I know that neither of us alone can persuade you, but you must remember that we are both worried about you, and we hope that you can come back unharmed." Schuchman, who has a straightforward personality, can't say such things, and naturally only Hogg is the only one who is playing the family card with Lu Yuanda at the moment. "You have to remember that if you can't do anything, you should withdraw immediately, and let's go back to Shanghai." Schuchmann also spoke to Lu Yuan.

Lu Yuan didn't say anything, just accompanied the three of them to have dinner calmly, and then went down to the basement, first completely vacated his storage space, and then only brought some weapons and equipment that must be used. When night fell, Schuchman personally drove Lu Yuan out of the American Concession, watching Lu Yuan's back slowly disappear into the alley on the corner, Schuchman drove back to the firm and waited for the dawn to come. The first thing Lu Yuan did after entering the alley was to change into the combat equipment in the storage space, and Lu Yuan, who had a full-view map, was not afraid of encountering the Japanese army in the city.

Coming out of the other end of the alley, Lu Yuan was already in a state of being ready to fight at any time, not only had he already put on his steel helmet and face armor, but also the assault rifle had been attached to the gun belt on his chest. Lu Yuan, who came out of the alley, walked south, and felt out the silencer and screwed it on the barrel of the assault rifle, in the full-view map he had opened, the neighborhood he was in was basically safe.

Several young people who looked like students suddenly rushed out of the alley on the side of the street, and suddenly saw Lu Yuan's dress, these students were obviously frightened, and they all stood on the side of the street with a bewildered look. Lu Yuan didn't pay attention to them, just glanced at them, and continued to walk south along the side of the street. At this time, it was still early, although there were suddenly a lot more Japanese in the city, but there were still many residents in the city who traveled after dark according to their habits, and Lu Yuan did not meet many pedestrians who were frightened by him along the way.

It's just that Lu Yuan doesn't care about these things at all, he already has his own plans for changing into combat equipment in advance, and those who have been hiding their heads and tails may not be helpful to his plan. On the way, Lu Yuan even encountered two traitor spies who were working for the Japanese, Lu Yuan did not shoot them, but still left safely by these two guys like other passers-by. But a few minutes later, Lu Yuan, who was heading south, suddenly changed the route of travel, and after quickly changing clothes, Lu Yuan went directly to the dock area.

Ten minutes later, the Japanese military police headquarters suddenly received a report from a checkpoint in the city, saying that the field service members of the Rational Mathematics Special High School had seen a suspicious element, and according to the description, the checkpoint believed that this suspicious element was probably a resistance element that had recently opposed the Japanese army. The Gendarmerie Command, which received the information, immediately dispatched troops to encircle and search the area south of the city in accordance with the report from the checkpoint.

Through the glass window of the coffee shop, Lu Yuan watched with a smile as one after another Japanese military trucks drove through the street, and none of these Japanese military trucks were driving towards the south of the city. Lu Yuan only drank half of his coffee before getting up and leaving, leaving the coffee shop, he plunged into the alley opposite, and then came out from the other end of the alley, Lu was already very close to the port. The warehouses Hogg mentioned were in the port area, but Lu Yuan's immediate delay was not to confirm the existence of those warehouses first, but to clear the Japanese guards here little by little.

It wasn't until a barbed wire fence appeared in his sight that Lu Yuan, who was moving forward, finally stopped, took out the iron tongs from the storage space, and it didn't take long for Lu Yuan to make a gap in the barbed wire that could enter and exit freely. Waiting every day, without looking around, Lu Yuanjing drilled through the gap in the barbed wire. On the other side of the barbed wire fence is the port area, where Hogg's warehouse is located, and Lu Yuan has confirmed that there are many Japanese guards here.

Lu Yuan moved forward quickly, and when he moved to the nearest cargo pile, Lu Yuan stopped, and immediately knelt on one knee to make a posture that could be ready to fight. After about a dozen breaths, the originally faint footsteps gradually became clear, and soon, the figure of a group of Japanese patrols appeared in Lu Yuan's sight. Lu Yuan slowly put his assault rifle on the side, there were 12 Japanese soldiers in this Japanese patrol, Lu Yuan didn't know if he could kill these 12 Japanese soldiers quietly, but he still decided to give it a try.

Lu Yuan, who was kneeling on one knee, leaned sideways against the pile, and after those Japanese patrols walked on the other side of the pile, Lu Yuan immediately got up and bypassed the pile and quickly followed. There was a soft sound of "poof", and the Japanese soldier who was at the end of the Japanese patrol was shot in the back of the head, and his body immediately fell down as soon as he became weak. As soon as the blow was successful, Lu Yuan, who was following behind, had no other concerns, just quickly pulled the trigger of the assault rifle, and after a series of light sounds, the entire patrol of the Japanese soldiers were all shot and fell.

After replenishing the guns of the corpses of these Japanese soldiers according to the custom, Lu Yuan began to drag the corpses of these Japanese soldiers who had been stripped of their weapons and ammunition to the fire to hide, as for the rest of the weapons and ammunition, they had naturally been put into the storage space by Lu Yuan. Relying on his full-view map, Lu Yuan gradually touched the interior of the port area, and there were more than three Japanese patrols that were attacked by him, which means that at least half of the Japanese soldiers had been successfully shot by Lu Yuan.

Hogg did not inquire about the specific location of the secret warehouses of the Japanese army, so Lu Yuan could only search and check the warehouses he saw one by one. The hard work paid off, and after more than ten minutes, Lu Yuan finally found a so-called secret heron of the Japanese army, and found three boxes of high explosives in a corner of the warehouse. "Damn, that's not enough for me to stuff my teeth." The three boxes of explosives in front of him did not satisfy Lu Yuan, and this amount of explosives was still far from the number Lu Yuan expected.

Looking around at the other weapons, ammunition, and equipment stacked in the warehouse, Lu Yuan loaded two boxes of grenades and one box of Tomosaka rifle cartridges into his storage space before he began to arrange bombs and mines in the warehouse. "Hmph, I can't take it with me, and you don't want it." Lu Yuan arranged more than a dozen mines and bombs in this warehouse full of weapons and ammunition in one breath, and no matter which of these mines and bombs was triggered by the Japanese army, it was the arrival of the end.

Lu Yuan was not satisfied with three boxes of explosives, so he continued to search for other warehouses in the port area, and in a small warehouse surrounded by many goods, Lu Yuan finally found the explosives he needed. Stuffed his storage space with explosives, looking at the remaining explosives, Lu Yuan was a little worried, he really couldn't bear to destroy these remaining explosives, at this moment, Lu Yuan suddenly regretted that he didn't ask Schuhman to drive to pick him up, maybe that would take away more explosives.
