Lu Haoyu pointed out many defects in bricks and cement, and immediately suppressed the soldiers of the whole platoon, and even the second platoon commander was stunned on the spot. He picked up a piece of brick and mud and reflected silently.

Lu Haoyu took the opportunity to return to the essence of science and technology again, and turned it out to calculate the current situation of logical analysis at the first level, with an advantage of 1.5 layers, including 1 layer of active conditions and 0.5 layers of specialist aura. If he wanted to enter the third company as an auditor, this skill was not enough, and when he saw Hou Xiaoxian, who was also shocked in the distance, he had an idea.

"You, old rag, come here."

Hou Xiaoxian was surprised in his heart, he didn't understand, he was obviously in a gang with 9527, seeing that he was pretending to train the second platoon of soldiers to be in a good place, why did he suddenly rush to himself. Hou Xiaoxian was frightened, and kept squeezing his eyebrows with Lu Haoyu.

"Don't squeeze your eyes, squeeze them again, and your little eyes will be gone."

Lu Haoyu didn't eat Hou Xiaoxian's set, which made him annoyed in his heart, but he didn't dare to attack, he stood honestly on the spot, and his heart was up and down, I don't know what Lu Haoyu had in mind.

"Old tattered, let me ask you, what is the purpose of the master's affection to build our three consecutive two rows? What is the task of our second platoon? Say it boldly, don't be afraid, someone wants to target you, and I, the commissioner, will carry it for you. ”

His last sentence was for the entire second-row soldiers, although the second row had opinions on Lu Haoyu's "broom star", but he had a good impression of Hou Xiaoxian, and he was even more loyal to the master, and Lu Haoyu stood at the height of Ye Guchen, the master, to teach the soldiers of the second row a lesson, and forced to bring the aura of the commissioner, and the advantage changed from 1.5 to 2 layers in an instant, and there was still the last layer left.

He naturally knew about the scientific research projects and tasks of the second platoon, and since Lu Haoyu did not target him, Hou Xiaoxian was of course willing to cooperate.

The main task of the second platoon, one is the basic building, the main direction is the protection work on the city wall of the college entrance examination, but this is not the main direction, after all, the war is the era of cold weapons, even if it is a siege battle at the level of the college entrance examination, the damage to the city wall is not very serious, in other words, to a certain extent, this is just a dispensable project.

The second project is the steel array, in the college entrance examination, not only from the imperial army siege test, but also part of the artificial rain, in fact, artificial rain. Rain can not be taken seriously for humans, even if it rains heavily, it can't hurt human fur, but it's completely different for small soldiers, after all, small soldiers are only 2 cm tall, as long as a grain of rain, it is possible to smash small soldiers to the bone damage, pouring heavy rain can even make small soldiers crushed.

The shield array developed by the first row is not specifically aimed at the imperial army to some extent, but more because of the artificial rain robbery in the college entrance examination, while the steel reinforcement array in the research and development direction of the second row is mainly to deal with the flood caused by the rain, in order to protect the soldiers, the formation that the soldiers can avoid the flood catastrophe.

Lu Haoyu pricked up his ears and listened very carefully, and at the same time he observed the soldiers in the second platoon around him, when Hou Xiaoxian stated, most of them lowered their heads, especially the second platoon leader, they felt that their faces were gloomy, the scientific and technological development of the second platoon was very slow, and it was at the bottom of the three platoons, which made them feel ashamed.

"Old and tattered, so to what extent has the steel bar array been developed now?" Lu Haoyu asked very slowly, and his voice was even longer.

Hou Xiaoxian was stunned for a moment after being interrupted, he finally understood Lu Haoyu's heart.

"Commissioner Qiqi, the overall plan has been determined, but the full development is very slow, and the structure of the reinforcement has not worked well in several tests."

"Take me to see", Lu Haoyu said in a loud voice, but it was full of majesty and unquestionable.

Hou Xiaoxian's eyes lit up, and he stepped forward quickly, pulling the second row leader with one hand, and guiding Lu Haoyu with the other hand to the assembly site of the steel bar array. Hou Xiaoxian, an auditor of the scientific research progress of the second platoon, would not know the specific progress, so he pulled the second platoon leader. In addition, he also has ulterior motives, in case the little ancestor in front of him can't find anyone when he trains people again, what if he sprays himself, there is a second platoon leader to do the back, and it will not affect him.

Before the second platoon commander recovered from the trance just now, he was pulled to his scientific research site by outsiders in a daze.

Hou Xiaoxian explained beautifully: "Your Excellency, this is the component of our steel bar array. ”

"I didn't hear clearly, what did you say it was?"

"This?" Hou Xiaoxian saw Lu Haoyu with a straight face, a serious look, and knew that he was going to start slapping his face, and he couldn't be unprovoked by the wind, so he pushed the second platoon leader to the front.

"Commissioner, the research results here, the old tattered don't know in detail, let the platoon commander explain it to you."

The second platoon commander also has no scruples, although he has not fully believed in Lu Haoyu's identity as a commissioner, but since he is a person sent by the master, he still has to pay attention to it.

"This is a rebar component that we have been building for a long time."

"How are your rebars made?" Lu Haoyu interrupted him directly.

"At least nine times of forging and polishing, we have carefully forged the thick steel bars of human beings again and again, and finally made them into steel bars for our small soldiers, and they have been refined into steel."

"It's polished, and it won't be ground with fine wire, right?" Lu Haoyu has the memory of a human being, and according to the proportion, the thin wire is thicker than an arm in the eyes of the little soldier.

"What thin wire, you're insulting...", the second platoon grew angry.

Before the second platoon leader finished speaking, Lu Haoyu held a steel bar with his left hand and knocked it the ground, and the front end was bent.

"Is this your nine forgings? Is it still made into steel? Do you know what is made into steel? Are you kidding me, or are you making fun of me? Lu Haoyu said that the second platoon leader's face was red and white.

"What does the rebar look like in the commissioner's mind?"

"Hundred refining into steel is to be smelted, I admit that your nine forging will increase the toughness of the steel bar to a certain extent, but unfortunately this thing is born with thin iron wire, the base material is not good, no matter how you refine it, it will be in vain. In my opinion, these are not steel bars at all. The process of smelting, which is to melt all the metal and then refine it, is the real refining. ”

The second platoon leader was speechless, he finally saw Lu Haoyu's scientific and technological level, which was simply unfathomable, although smelting was considered a second-level technology in the Xuanwu Empire, it could not reach that level in the Heavenly Dream Regiment. To be able to speak the theory of smelting, I am afraid that only the master of the entire Heavenly Dream Troupe, Ye Guchen, has such common sense.

"To answer my question first, why don't you use smelting, but use this forging method to form, don't you know that you are tired?"

The second platoon commander explained helplessly: "Because the smelting furnace we have mastered, the temperature cannot rise, if we use the master's own smelting furnace, the fire is too big and uncontrollable, so we can only choose forging." ”

"I'll discuss the problem of the smelting furnace with the master in the future, but I found that the front end of each steel bar, what did you smear?"

"It's a natural rubber, and we use rubber to glue the rebar to the rebar together."

"Can rubber stick to metal? Ah, who told you that rubber can stick to metal? ”

"No, can't you?" Lu Haoyu's strong attitude caused a lot of psychological pressure on the second platoon commander.

"Who told you no? Rubber can't stick to metal, so what material is used for water pipes to come into contact? ”

"So, can it stick?" Lu Haoyu's repeated questioning confused the second platoon commander.

"It can be sticky, but it can't be glued with water-based glue, which will weaken the stickiness of the glue as soon as it comes into contact with rainwater, making it not suitable for outdoor use. Your large array of steel bars, if it rains, will instantly become a pile of rotten iron. ”

After hearing this, the second platoon commander broke out in a cold sweat, and the steel bar array they developed was to resist the flood after the rainfall.
