"Impossible, Fushan Bank is in Hongkou District, and our people have no way to find out about the bank, especially if you are asking about the situation of the bank's vault." Xu Huanshan, who also learned the inside story, also praised the North Koreans' brains that were bigger than the sky, but Xu Huanshan said that he could not do anything about Lu Yuan's rescue. It's just that Lu Yuan didn't think much of Xu Huanshan's powerlessness, and said in his heart that he was giving benefits to your underground party for nothing, how could this be such a reaction.

"Lao Xu, you have to think clearly, Fukuyama Bank is related to the Japanese imperial family. If the methods of those North Koreans work, when the time comes, we will not be able to get a fraction of it, maybe a few hundred kilograms or even more of real money. Lu Yuan's pillar of smoke turned, and began to persuade Xu Huanshan with all the temptation, hundreds of kilograms of gold and silver, that is really not a small amount, Lu Yuan does not believe that Xu Huanshan is not moved.

Lu Yuan thought that Xu Huanshan could not refuse his lobbying, but who knew that after Xu Huanshan closed his eyes and pondered for a while, he still objected. "Even if you're right, the North Koreans are digging a tunnel to the bank's vault, but how do you know that the Japanese bank's vault must have a lot of gold and silver? Such a tunnel will definitely not be hastily excavated in a short period of time, especially the large amount of earthwork excavated, those North Koreans have no way to hide and dispose of it, and I believe that the tunnel was dug by the North Koreans a long time ago. ”

Xu Huanshan's words made Lu Yuan also shake a little, and he immediately asked Xu Huanshan with a hesitant face, "Then what do you mean?" Do you think this would be a trap? ”

"I think there's something weird about this thing itself." Xu Huanshan's answer was beyond Lu Yuan's expectations, "What do you think, how can those people from the Korean National Salvation Army know about the relationship between this Japanese bank and the Japanese imperial family?" Even if they had access to the information, how could they be sure that the bank's vault would have gold and silver in it? The last and most important question is that they may be able to dig tunnels through the vaults of the Bank of Japan, but how can they quietly take away the gold and silver? You and I both know the weight of gold. ”

Xu Huanshan's series of questions made Lu Yuan also fall into deep thought, but after a while, Lu Yuan suddenly sighed. Get up from your seat and stand up. Xu Huanshan's questions just now really caused Lu Yuan a lot of confusion at first, but after he thought of his storage space, all this kind of trouble disappeared. Yes, I have storage space, and the last time I attacked the dock warehouse, I had already experimented with using storage space to make holes in the walls, and digging tunnels seemed to be not much different from digging holes in the walls.

As soon as he thought of this, Lu Yuan immediately made an association in his mind, if the tunnels dug by the North Koreans were really leading to the Bank of Japan across the street. Then, you can wait and see what happens, and then look for an opportunity to be a yellow sparrow. Lu Yuan didn't know what kind of means and methods those Koreans would use to take away the gold and silver in the vault of the Bank of Japan, but he knew that as long as his storage space was still there, the vault of the Bank of Japan would store mountains of gold and silver, and he was afraid that it would not be enough for him to even end his nest at that time.

Lu Yuan's excitement also interrupted Xu Huanshan's contemplation, but it was impossible for Lu Yuan to tell him the most secret thing in his heart, pretending that he was sitting on a numb leg just now, and Lu Yuan cleverly prevaricated Xu Huanshan. Lu Yuan, who already knew it in his heart, was like a master who had opened up the second line of Ren Du at this moment, and he straightened out everything else in an instant. Lu Yuan, who already had a plan in his heart, immediately said goodbye and left, no matter what the idea of those North Koreans was, Lu Yuan had already made up his mind to cut off his beard halfway.

Leaving Xu Huanshan's residence, Lu Yuan returned to the surveillance point again, and sure enough, there were only five people in the residence of those North Koreans. Lu Yuan, who had a good night's sleep, recuperated his spirits, and went straight to Hongkou District early the next morning. Lu Yuan fought with the Japanese army in the concession some time ago, and the Japanese in Shanghai were a lot more careful, which indirectly caused the extremely lively Hongkou District, and many Japanese living in other concessions moved back to Hongkou District.

After wandering around Hongkou District all morning, Lu Yuan finally found a rental house near Fushan Bank, although Lu Yuan found a loft of knowledge, but looking out from the window of the attic, he could just see the hotel and Fushan Bank. After two days of secret surveillance, Lu Yuan finally discovered how the Koreans in the hotel transported the soil.

The Japanese have controlled the Korean Peninsula for a long time, and the Japanese have looked down on the weak Koreans from the bottom of their bones, but there are many Korean servants in many Japanese homes, even among the Japanese living in Shanghai. There is also a North Korean repair team in Hongkou District, whose main task is to repair roads, drainage ditches and other public facilities in Hongkou District, as well as to collect and transport feces from Hongkou District every day.

Most of the repair team was equipped with hand tools, but there were also a few old trucks, one of which was usually used to haul tools and equipment, while the remaining vehicles had been converted into manure trucks, which were parked just across the wall from the hotel. Trucks that haul tools can't leave Hongkou, and those that specialize in hauling manure come in and out of Hongkou five times a day, and if these trucks fail, at least a third of the Japanese in Hongkou will be clogged with toilets in front of their homes.

Finding that the manure trucks that entered and exited Hongkou District every day were parked next door to the hotel, Lu Yuan took advantage of the night to carry out on-the-spot reconnaissance again, and found that the North Koreans in the hotel really quietly loaded the excavated soil into the manure truck. Although these North Koreans are very careful, and each manure truck does not contain a lot of soil, there are several manure trucks, and these manure trucks enter and leave Hongkou several times a day.

Figuring out where the dirt went, Lu Yuan immediately turned his attention back to the hotel, and the distance between the hotel and the Bank of Fukuyama, Lu Yuan had already measured it on the spot. According to the actual distance between the backyard of the hotel and the Bank of Fukuyama, Lu Yuan calculated the amount of soil that the North Koreans needed to dig out to dig the tunnels.

As the day of the Navy Reception approached, Lu Yuan suddenly noticed that the middle-aged man had begun to enter the hotel more often, and Hans had also received news from the black market, and recently, someone had inquired about the price of standard rifles in the black market. These North Koreans are digging tunnels, obviously coming for the Bank of Fukuyama, but why do they need standard rifles? Lu Yuan had no doubt that the information transmitted by Hans was wrong, but he just couldn't understand why these North Korean people were still making trouble.

In order to understand the doubts in his heart, Lu Yuan even went to the scene of the Navy Cocktail Party, but he carefully looked at the surrounding terrain and really couldn't find the conditions suitable for long-distance sniping. Could it be that I am different? Lu Yuan, who returned to the surveillance point, looked at the hotel from a distance through the window, in fact, from the beginning, when he learned that the Japanese army was going to hold a naval drinking party, it was Lu Yuan's own wishful thinking that those Koreans were coming for the drinking party.

Lu Yuan, who found the key point, suddenly realized that he dared to love that he was different, maybe these people from the Korean National Salvation Army might have other tasks in Shanghai. A day later, Hans called again, saying that he had finally found out from the black market that the Bank of Fukuyama had received a shipment of precious metals from the Japanese troops going south two weeks earlier. This belated news lifted Lu Yuan's spirits, and the incubation for several days was finally not in vain, Lu Yuan thought that without further ado, it was time to act.

Lu Yuan decided not to continue to lurk, he asked Amashi to start acting, God also seemed to be helping Lu Yuan, and after lunch, it suddenly rained lightly. Although the rain was small, it was dripping and dripping, and the rain did not stop until the sky finally darkened. Lu Yuan, who slept in the room for an afternoon, was in a good mood, went out to find a random place to eat something, and according to the plan he made, with the help of the cover of night and rain, he quietly turned into the backyard of the hotel.

On the full-view map that Lu Yuan had opened, it was shown that there was no one in the cave at the moment, and he carefully lifted the iron plate behind the flowers, and Lu Yuan saw the open entrance to the cave. The entrance of the cave went vertically down, and along the ladder in the hole, Lu Yuan climbed down for about ten meters before he could be regarded as descending to the point of the tunnel. Letting go of the ladder in his hand, Lu Yuan, who already knew that the tunnel was empty, immediately turned on his flashlight, only to find that the tunnel dug by these North Koreans was too narrow.

The tunnel dug by the North Koreans was very narrow, but the light pillar of the flashlight never hit the head, and Lu Yuan, who had already vacated the storage space, immediately moved. Continuously put the soil into the storage space, Lu Yuan instantly expanded the tunnel to a scale large enough for himself to bend over, during which he transferred the soil filled with the storage space to the corner of the hotel yard twice in a row, and Lu Yuan measured the length of the tunnel that was expanded by himself, which was close to 30 meters.

The length of 30 meters is about the same distance from the backyard of the hotel to the front of the Busan Bank if you follow the distance measured by Lu Yuan on the spot before. Lu Yuanxin said that he might transfer the soil twice more, and maybe the tunnel could be dug under the bank vault! But at this moment, Lu Yuan, who was climbing up the ladder, suddenly heard a voice from outside the tunnel entrance.
