Naturally, the Japanese army's attack was still ineffective, but their attack reminded Lu Yuan and the others that the Japanese army could attack the hall on the first floor at any time. When cleaning up these corpses, Lu Yuan and the others did not find many bullets from the corpses, and there were not a single one.

Not having enough ammunition means that you can't continue to hold on, and not having enough * means that you may face a tidal wave of Japanese attacks at any time, and it may only take one Japanese crowd attack to drown the two of you under the bayonets of Japanese soldiers. Jin Douhuan was flustered about this, and turned his head to look at Lu Yuan, but saw that Lu Yuan's face was still unfazed.

"Pop" A bulging backpack appeared in front of Jin Douhuan, and Jin Douhuan subconsciously looked up, just in front of Lu Yuan's unfazed face. Xu sensed the other party's panic from Jin Douhuan's expression at this moment, and Lu Yuan immediately said with a smile, "There are 200 rounds of ammunition in this backpack, and there are 20*, which is enough to repel two more attacks by the Japanese army." Hearing Lu Yuan's words, Jin Douhuan was about to say what this ammunition was enough for, but out of the corner of his eye, he suddenly saw that at Lu Yuan's feet, such a backpack also appeared.

If the backpack in front of Lu Yuan's feet was also full of ammunition, if the amount of ammunition was the same as his own backpack, 400 rounds of ammunition and 40 pieces*, it would naturally be enough to repel the two attacks of the Japanese army. Thinking of this, most of the panic in Jin Doohuan's heart dissipated slightly, but he still couldn't help but wonder, what would he do if all these ammunition were also used up? After the last attack of the Japanese army was repulsed, there were people shouting in Korean outside the bank building, Kim Doo-hwan was a Korean, so he could naturally understand what the Japanese soldiers outside were shouting, and the Japanese troops outside the building wanted to surrender by themselves and sneak attack Lu Yuan to help the Japanese take this place.

Kim Doo-hwan didn't know if Lu Yuan could understand Korean, but he secretly paid attention to Lu Yuan's expression and didn't see anything. However, Lu Yuan's terrifying marksmanship and reaction speed had already left a deep memory on Jin Doohuan, and Jin Doohuan didn't know what the chances of success would be if he secretly attacked Lu Yuan. Jin Doo-hwan's careful thoughts, Lu Yuan naturally didn't know, but the full-view map that Lu Yuan opened was also scanning Kim Doo-hwan all the time, as long as Kim Doo-hwan had bad intentions, the full-view map would definitely show the color change of the small dots representing Kim Doo-hwan.

This is Lu Yuan's ultimate means of being wary of Jin Doo-hwan, as long as Jin Doo-hwan's color in the all-view map does not appear to represent hostile red, Lu Yuan will not mind helping him and help him escape. But at this moment, looking at the strange color in Jin Doohuan's expression, Lu Yuan knew that this North Korean might have something in mind, such a guy must not leave the other party to continue to live in this world. It's just that now is not a good time to rectify the other party, the Japanese army outside the building is still eyeing each other, and it is just past lunch time, and I hope to delay the time until night.

"You keep this place, I'll go to the top of the building and have a look." Lu Yuan, who had already noticed it, still did not move, and after explaining a few words to Jin Douhuan, he quickly walked to the top of the building. The Japanese soldiers outside the building also arranged veterans with good marksmanship at the heights of the surrounding buildings, but the attention of these Japanese veterans was on the front entrance of the bank at the moment, but they didn't expect that Lu Yuan would quietly go to the roof of the bank at this time.

Before he got to the rooftop, Lu Yuan lowered his figure, and at the same time felt out * and screwed it on the assault rifle hanging from the gun belt on his chest. Perhaps because he felt that there were many people, the Japanese veterans who were distributed on the rooftops of the surrounding buildings did not hide their body shape at all, which in Lu Yuan's opinion, was simply stupid. Lu Yuan, who was about to stop, did not stand up and raise his gun to shoot, but first used his storage space to dig out a fist-sized hole under the cement guardrail at the edge of the rooftop, and then slowly poked out the barrel of the gun through this hole.

The Japanese soldiers who were placed on the rooftops of the surrounding buildings by the Japanese army were far and near, and it was said that it was safer to strike the closer ones first, but Lu Yuan chose to shoot the Japanese soldiers who were far away first. The long twist of medicine was ignited by a lighter, and Lu Yuan raised his hand and threw the string of firecrackers he was carrying just now into the distance. In the next second, the firecrackers that were still in the air were already sounding, and if you didn't listen carefully, the movement was no different from shooting. Not only were the Japanese soldiers outside the building attracted their attention by the sound, but even the Japanese shooters on the rooftops of the surrounding buildings, but Lu Yuan seized the opportunity to shoot again and again.

Before the Japanese could react, Lu Yuan, who had already fired at least half of the bullets in the magazine, shot and killed a number of Japanese shooters who were placed high around him. Seeing the blood mist bursting out not far away, the other Japanese shooters who were placed on a high place could be regarded as reacting, but they were in a hurry to respond, and they didn't even find where the other party was. The gunshots rang out, but they were scattered and aimless, but Lu Yuan's counterattack was very sharp, and immediately two more Japanese shooters were killed by Lu Yuan on the roof.

It was not until this moment that the anxious Sato Usuke finally understood why the other party chose this bank building as a base, because around this bank building, there were no other buildings higher than the bank, and the other party only needed to occupy the roof of the building and shoot condescendingly. If it weren't for the fact that the other party had created such a chaotic situation in the Hongkou District, and had shot so many Imperial soldiers under his command, Sato Yousuke would have even wanted to have a good talk with this opponent.

The Japanese shooters who were placed on the heights around by Sato Yousuke were quickly defeated, whether it was weapon performance or tactical thinking, they were not Lu Yuan's opponents, and in the end, less than half of the Japanese shooters who could withdraw alive were not the first half. Leaving more than 20 corpses on the other side to evacuate in a hurry, Lu Yuan on the rooftop was finally able to get up from the ground, but the first thing he did after he got up was to immediately switch to a sniper rifle and shoot at the Japanese soldiers in the street.

At this time, Lu Yuan on the rooftop, like a lonely fighter, kept moving back and forth along the guardrail on the edge of the rooftop, and the bullet casings that withdrew from the chamber of the gun were also quickly sprinkled on the rooftop, reflecting a dazzling golden yellow under the sunlight. Lu Yuan on the rooftop, like a tireless fighter, kept moving his position at the same time, and quickly emptied several spare magazines, and then looked at the streets below, no Japanese soldiers dared to take the initiative to show their figures.

Jin Doo-hwan, who was left by Lu Yuan to defend the main gate, didn't know what was happening outside, but as the gunfire continued, Kim Doo-hwan, who moved to a window facing the street, was surprised to find that the Japanese soldiers in the street outside were all hiding. Seeing that the soldiers of the once invincible Imperial Japanese Army would also show such an unbearable scene, Jin Doohuan couldn't help but laugh, but at the same time, Jin Doohuan also had a new understanding of Lu Yuan's strong combat effectiveness.

Condescendingly, and using sniper rifles to shoot at the Japanese army, Lu Yuan's advantage increased exponentially, and the corresponding Japanese army went into hiding. After emptying several magazines in a row, the Japanese soldiers could no longer be seen in their sight, and Lu Yuan, who was numb in his shoulders, finally stopped, and after a short pause, Lu Yuan came down from the roof. Lu Yuan went downstairs, but did not return to the corner of the stairs on the second floor, but went straight into a room on the second floor.

Lu Yuan explained to Kim Doo-hwan, saying that he would sleep for a while, but in fact, he used the storage space to dig out a hole in the floor of the room, and then went down smoothly from this hole to the room on the first floor. This is a bank building, naturally there is a basement, of course Lu Yuan is looking for a basement for money, twenty preparations to prepare a retreat first. It was too sharp to make a hole in the storage space, and in just a quarter of an hour, Lu Yuan found the basement of the bank and used the storage space to break through the cement wall of the basement.

The area of the basement is not very large, Lu Yuan ignored the gold bars and banknotes in the basement, but opened a hole in the southeast corner of the basement, according to Lu Yuan's layout in advance, he only needs to dig a hole in this direction, only need to dig 200 meters, and he can connect to another tunnel that Lu Yuan has dug a long time ago. With the tunnel, Lu Yuan can advance and retreat freely, and he can even transfer to other places in the shortest possible time to continue attacking the Japanese army.

Kim Doo-hwan, who had been guarding the stairs on the second floor, didn't know about these things, and Lu Yuan didn't plan to tell the other party at all, if it weren't for Lu Yuan's need to divert the attention of the Japanese army and delay time, he wouldn't have mentioned Kim Doo-hwan's name in front of the Japanese army at all. About half an hour later, Lu Yuan stepped on the ladder and returned to the second floor, and at his insistence, the equally tired Jin Doo-hwan just nestled in the corridor and slept for a while.

Time passed little by little, and Lu Yuan's purpose of delaying time was finally achieved, although the Japanese army launched another attack before dark, but they were still repelled by Lu Yuan and the others again. As night fell, Kim Doo-hwan began to get nervous, but Lu Yuan began to move his body to organize his equipment. "Don't worry, you stay here, I'll get some ammo and come back." Ignoring Jin Doo-hwan's stop, Lu Yuan just explained to the other party and slipped down to the first floor like a tanuki.

The Japanese soldiers outside the building obviously thought of this, and after nightfall, several fires were burning outside the bank building, and if Lu Yuan wanted to leave the bank building, he would definitely be exposed to the sight of the Japanese army. But Lu Yuan is not an ordinary person, after looking out of the open street window for a while, Lu Yuan suddenly walked to the corner of the hall and lifted a table that had been turned over, and took out a grenadier from under the table. Jin Douhuan, who was squatting on the second floor, looked straight at his eyes, he didn't expect that Lu Yuan was still hiding a big killing weapon like a grenadier in the hall on the first floor.
