The next day, the tired little devils started working on the battlefield early, and these little devils all wore panda eyes, highlighting the tired and helpless eyes that seemed particularly unenergetic.

After Wang Si and the others came out of the tent, they couldn't help but want to laugh when they saw the devil's situation, but they tried their best to hide it in their hearts to prevent themselves from laughing.

They didn't expect that yesterday's chaos would actually let the little devils fall into this kind of field, and now when they see these panda-eyed little devils, they naturally feel particularly funny.

Han Zhengdong was a little breathless, and almost laughed out loud when he saw the scene of the devil, but he was glared at by Wang Si's sharp eyes, which restrained him a little.

After that, Wang Si led them and continued to walk towards the front line, towards the side of the dark castle.

The Dark Castle had been repaired by the little devils, but it still hadn't been improved, and it sank again in less than a night, this time into the dirt, leaving only a bald one outside.

Looking at this posture, this bald head will not last long, and it will sink towards the ground. It's like a bottomless pit in the dirt, and no matter what they do, there is only one result, and that is to sink into the dirt.

"Takeda-kun, you're here!" The devil Zhongzuo was already in a daze in front of the dark castle at this time, and when he saw Wang Si and them arriving here, he immediately said to Wang Si, "Look at this, we worked hard yesterday, and the result is still like this, it really makes me anxious, I don't know what to do!" ”

"Your Excellency doesn't have to worry, your subordinates are here to solve this problem for you now!" Wang Si immediately said to the little devil, the devil spoke very fluently, but I am afraid that all the little devils have no way to find out what is wrong with it.

"Oh? So Takeda-kun has a corresponding way? Hearing Wang Si say this, the devil Zhongzuo immediately showed a happy face, and immediately said to Wang Si.

"Of course!" Wang Si said with certainty that he felt that this was the time for the little devil to believe him, so naturally he didn't plan to hide it, and more importantly, he needed to hurry up and solve the matter here, leave here as soon as possible, and solve the problem of the team's guns.

"Then please ask Takeda-kun to teach me!" At this time, Qingchuan and Yokohara also came to Wang Si's face, and just saw Wang Si's conversation with the devil Nakasa, so Qingchuan immediately walked in front of Wang Si, bowed his head to Wang Si and said such a sentence for the first time.

For the little devil, it is an imminent matter to solve the current sinking of the dark castle, and he can't afford to delay it at all, since Wang Si said that there is a way to deal with it, then he naturally wants to get the answer as soon as possible, so as to tell the devils around him to hurry up the construction and solve the current trouble.

"Your Excellency Qingchuan doesn't need to be polite, I'll tell you my opinion!" Wang Si didn't intend to be stingy, and said directly to all the devil officers present.

"Takeda-kun, please!" Seeing that Wang Si was about to say the plan they had been waiting for for a long time, everyone remained silent and all stood in front of Wang Si and listened.

Seeing that everyone was quiet, the devil Zhongzuo politely said a word of invitation to Wang Si, although it was brief, but it showed his urgency and expectation for this matter.

"Actually, it's very simple, our bunker building is too heavy, coupled with the swamp formed by the dark river underground, even if we build more bunkers, it will be difficult to escape the fate of sinking into the quagmire!" Wang Si saw that those little devils were all looking at him, so he immediately analyzed and said to such a pair of little devils, "To solve this problem, there is only one way, increase the buoyancy under the dark fort, and make our dark fort a floating ship, so that there will be no more possibility of sinking!" ”

Wang Si continued to speak very seriously, and informed all the little devils present of all the details. He asked the little devil to replace the reinforced concrete used in the original bunker with a wooden support, and change the cement and sand used to build the bunker into hollow bricks, so as to reduce the weight of the bunker building.

The ground area under the bunker building is then expanded by more than four to five times, all made of wood and empty fuel drums, so as to increase the contact area between the bunker and the underground swamp and prevent the bunker from sinking.

In addition, in advance, on the ground where the bunker is to be built, make a few pipe holes, and pour gasoline and other floating materials into it to increase the buoyancy of the surface of the underground swamp, and make a complementary contact with the contact surface of the bunker above.

Everything is interlocked, and I believe that under this plan, it will be more difficult for these two dark forts to sink than to ascend to the sky.

After listening to Wang Si's statement, the whole plan has been presented in front of the little devil, everyone was dumbfounded, and the devil Zhongzuo immediately said to Wang Si: "Takeda-kun is really the best architectural talent in the empire, the plan given is practical, everything is just right!" ”

"Your Excellency is too famous, in fact, you are only doing a little bit of your best in the lower area, and the defense of this area still needs Your Excellency and many commanders, who are just a passer-by, I just ask that the commanders can return to the team when the dark castle is completed!" Wang Si heard the other party's praise and immediately said to the devil Zhongzuo.

In the current situation, he almost believed that his plan was seamless, after all, he had done every link interlocking, and he was not a special person, so he was afraid that he couldn't see the problems in it.

"It's nature!" Hearing Wang Si's words, the devil Zhongzuo immediately assured. Although this plan has not yet been implemented, in his view, this is the best solution to the current troubles, and it is the kind of solution that cannot be replaced.

"Please!" Wang Si bowed ninety degrees in front of the devil Zhongzuo very respectfully, and then said to the devil Zhongzuo.

The devil Zhongzuo did not refuse, and immediately promised that as long as the dark castle was completed, Wang Si and the others would be allowed to pass through this defense area with their team, and he would give them a pass name along the way to ensure that they could return to Yuhang City as soon as possible.

After that, under the guidance of Wang Si, the little devil began to rebuild the dark castle in the location of the original building.

This time, they did not rush to build a bunker, but chose a few points to drill holes, and then poured gasoline and other oil that they could get into it, increasing the buoyancy and lubrication of the contact surface, and increasing the buoyancy and lubrication of the wood and gasoline drums and the ground, so as to ensure that the service life of these things increased.

Then there is the construction of the floating area, according to Wang Si's instructions, the devil soldiers arranged for the devil soldiers to start cutting down the surrounding trees to make an overall contact area, and cope with the weight of the bunker to be built with strong floating power!
