When Zhao Cheng and Lieutenant Okamoto were calculating the gains and losses, Lu Yuan, who had returned to the valley, was also discussing things with Xiao Haishan, and learned that Lu Yuan deliberately exposed this place to the Zhao family's family, Xiao Haishan didn't know what to say about Lu Yuan for a while. "Mr. Lu, although we are now saying that our troops have increased, everyone has been fighting for several days in a row, and with the transportation of materials, everyone's physical strength has been consumed a lot. If the Japanese army returns to attack here at this time, the situation will be very unfavorable to us. ”

Xiao Haishan's expression at the moment could be regarded as angry, but Lu Yuan said to Xiao Haishan with a smile, "Do you remember what the first two Japanese puppet army attacks were like here?" Which of their two attacks did not have more than 200 troops, and what was the result? It's not a failure. Lao Xiao, you shouldn't underestimate your strength, not to mention that there are hundreds of more Eighth Route Army to help this time. ”

Xiao Haishan is not a person who can't listen to the opinions of others, hearing Lu Yuan say this, Xiao Haishan immediately calmed down and pondered carefully, as if what Lu Yuan said just now was right. Seeing this, Lu Yuan added another fire, "Old Xiao, it will take at least one day to return to Zhaojiaji from here." Waiting for the intelligence to be reported, the nearby Japanese puppet army will send troops to gather troops, this is another day to pass, and then they will spend another day to rush over, and it will be three days outside here. ”

Lu Yuan smiled and stretched out three fingers and shook them in front of Xiao Haishan, "Old Xiao, three days is enough for your people to rest and recover their strength." Lu Yuan's words made Xiao Haishan suddenly, with three days of spare time, it was indeed enough for the guerrillas to recover their strength, and taking advantage of the three days, they could also let the Eighth Route Army get familiar with the terrain here. Thinking of this, the original worries in Xiao Haishan's heart instantly dissipated without a trace, and when he looked at Lu Yuan again, his eyes were already faintly relaxed.

Lu Yuan took the initiative to expose his location to those members of the Zhao family, which Xiao Haishan did not expect in advance, although he was persuaded by Lu Yuan, Xiao Haishan knew that he still had to persuade Xu Heizi and Wang Dahe. "What? You said that Lu Yuan used the Zhao family's family to drive the car on purpose? In order to attract more Japanese puppet troops here? Sure enough, as Xiao Haishan expected, when he told Xu Heizi and Wang Dahe the truth, the first person to react was the grumpy Xu Heizi.

After winning the county seat and Zhaojiaji in succession, Wang Dahe and Xu Heizi had already seen the hope of establishing a base here, and what they wanted most now was enough time. The news brought by Kexiao Haishan made their hopes of rushing to establish a base area tend to be dashed, once the Japanese puppet army attacked here on a large scale, all their energy and manpower would have to be used in the battle, where would they have the time and energy to worry about the establishment of a base area.

Regarding the establishment of the base area, Xu Heizi and Wang Dahe did not have time to tell Xiao Haishan, so Xiao Haishan did not know what the news he brought represented to Xu Heizi and Wang Dahe. Xu Heizi was already on the verge of an emotional outburst, but was stopped by Wang Dahe with his eyes, "Old Xiao, since Lu Yuan has decided to do this, he will naturally have his reasons." I see you just talked for a long time, did he tell you why? In addition, our people's physical exertion is too great, and once the Japanese puppet army attacks on a large scale, we may not be able to withstand their attack. ”

Wang Dahe's worries were the same as Xiao Haishan just now, Xiao Haishan had to smile bitterly, and carefully repeat what Lu Yuan had just told him, Wang Dahe and Xu Heizi looked at each other after hearing it, and the two of them understood in their hearts that Lu Yuan had obviously taken all the problems into account. Lu Yuan's analysis of Xiao Haishan is not unreasonable, and Lu Yuan and the two of them have amazing combat effectiveness, coupled with the terrain advantage of this valley, if the Japanese puppet army that comes to attack is less than 500 people, it will not pose any threat here at all.

Xiao Haishan has also been paying attention to the expressions of Xu Heizi and Wang Dahe, and seeing that the expressions of the two have eased slightly compared to just now, Xiao Haishan continued. "What Mr. Lu said is not unreasonable, our combined strength is close to 500 people, and we have the advantage of terrain. What's more, we have plenty of weapons and ammunition in our hands, plus those two Type 92 infantry guns, if the little devils come less, I'm afraid we won't even be able to see the mouth of the valley. "Those two Type 92 infantry guns are the biggest support of the guerrillas in Xiaojia Village, Wang Dahe was also ordered to bring a few artillery pieces this time, as long as the two Type 92 infantry guns exert their power, this valley can indeed be regarded as impregnable.

How Xiao Haishan persuaded Xu Heizi and Wang Dahe, Lu Yuan didn't care at all, while everyone else was carrying supplies, Lu Yuan took Huzi to the cave in the valley where the Japanese army originally stored supplies. The Japanese army occupied this place in order to build a secret airport, so when a large number of laborers were recruited for ground leveling, the Japanese puppet army brought a large number of materials for the construction of the secret airport, including a lot of cement and sand and gravel. The last time Lu Yuan built the mountain wall fortifications, he used some cement and sand and gravel, and this time, Lu Yuan planned to use up all the cement and sand and gravel in this cave.

"We probably only have three or four days to spare, so I need a lot of manpower, and we have to determine where and where to build the fortifications and move all the cement and gravel out of the cave before it gets dark today. As long as we hurry up, the cement fortifications can be dried before the Japanese puppet army arrives, and we only need a small amount of these cement fortifications to block the mouth of the valley. "How to use these cement and sand and gravel to build fortifications, I am afraid that only Lu Yuan is the most knowledgeable here, from later generations, he is very familiar with concrete buildings.

Xu Heizi and Wang Dahe had already been accompanied by Xiao Haishan personally, and had gone to see the mountain wall fortifications built by Lu Yuan before, and personally tested the solidity of the mountain wall fortifications, Xu Heizi and Wanda He were very interested in the concrete fortifications that Lu Yuan said, and after learning that cement could not be preserved for a long time, Wang Dahe and Xu Heizi immediately urged Lu Yuan to start building concrete fortifications. "Mr. Lu, manpower is not a problem, my battalion can draw out two companies for you. Before these soldiers joined the army, they were all good at their work, and you can mobilize them as you like. Wang Dahe directly sent the soldiers of the Eighth Route Army in Lu Yuan's two companies, saying that if the manpower was still insufficient, he could continue to send people to Lu Yuan.

With materials and enough manpower, Lu Yuan spread out his stall before dark, and under the light of a large number of torches and bonfires, the mouth of the valley has become a bustling and noisy construction site. The previous mountain wall fortifications were further repaired and reinforced, and Lu Yuan also mobilized manpower to build a stepped passage under the platform on the back of the mountain wall fortifications. In addition, on the opposite side of the mountain wall fortifications, Lu Yuan also mobilized manpower to build several machine gun forts out of concrete, so that these machine gun forts could form a crossfire on the valley mouth together with the mountain wall fortifications.

"The thickness of these fortifications is more than 50 centimeters, and there are steel bars inserted in the middle, which can at least withstand the shelling of all calibers of the Japanese army below 100 millimeters. As for the Japanese army's Type 92 infantry guns, drag our Type 92 infantry guns over and try a few shots, and it will be clear. "After a whole night of busyness, when the fish belly appeared white on the horizon, the hustle and bustle at the mouth of the valley gradually dissipated. Lu Yuan, who had been busy all night, was very satisfied with the forts that had been built, but Wang Dahe and Xu Heizi were still a little worried.

Lu Yuanyan said that these concrete fortresses could withstand the bombardment of the Japanese army's mortars with a caliber of less than 100 mm, Wang Dahe's heart was somewhat unconvinced, but the concrete fortress has not yet dried up, even if Wang Dahe has the intention to use the Type 92 infantry cannon to test, at least wait for the concrete fortifications to dry thoroughly. After a whole night of work, Wang Dahe's soldiers were very tired, and Lu Yuan was also very hard, and there was only one company of troops sent by Wang Dahe to serve as a guard.

Lu Yuan slept until lunchtime in a groggy sleep, if it wasn't for Xiao Haishan to wake him up, Lu Yuan might have been able to sleep until it was dark again. "Camp Commander Wang's subordinates have caught a few suspicious people on the side of Niutou Mountain, and I don't look like a good person." Xiao Haishan explained his intention, Lu Yuan didn't get up from the bed at all, but secretly opened the full-view map, and sure enough, in a corner of the valley, Lu Yuan found a few small red dots.

This must be a spy sent by the Japanese puppet army, Lu Yuan couldn't help but feel a little interested, so he got up and washed up, and followed Xiao Haishan to a corner of the valley. It was still the cave where the Japanese army had previously stacked cement and sand and gravel, and the soldiers under Wang Dahe used it for waste use, so they locked up those suspicious people here. After a few glances at the wooden fence, Lu Yuan had already made a judgment before Xiao Haishan beside him could see it clearly.

"Don't look at it, it's not a good thing, it's probably a spy sent by the Japanese puppet army." Lu Yuan's judgment surprised Xiao Haishan very much, but he looked at it for a while, but he didn't see any flaws. Seeing this, Lu Yuan explained, "You pay attention to the shoes they wear on their feet, this kind of rubber-soled shoes ordinary people can't afford to wear." There is also the long-haired left wrist, and the skin tone on his left wrist is obviously fairer than other places, which is not a birthmark, it should be because he has been wearing a watch for a long time. ”

Lu Yuan looked at Xiao Haishan with a smile, "Do you think ordinary people can afford to wear a watch?" Since they can wear rubber-soled shoes and watches, why do they wear them like Hanako, wandering around the world in the mountains? Lu Yuan's explanation made Xiao Haishan suddenly realize. What kind of life the people of the surrounding villages lived, he Xiao Haishan was very familiar with, and the common people would rather buy more grain and livestock if they had money, and would not spend money in vain to buy watches and rubber-soled shoes that they didn't need.
