Chapter 709: Strengthening the City Defenses

"General Lin, do you remember that some time ago, when we were waiting for the discussion, a cavalry battalion general mentioned that an iron wall should be poured to defend against the large siege equipment of the coalition army?" Seeing that the two had already known each other, Yan Nantian immediately got down to business.

"Remember," Yan Nantian reminded, Lin Xuanzhong finally remembered what this so-called fortification building was all about.

"Master Luo is the person responsible for pouring the iron wall," with a glance, Yan Nantian continued: "General Lin, don't think that pouring the iron wall is a simple matter, there are many difficulties that can only be solved by Master Luo. Seeing that Lin Xuanzhong already understood what they were doing, Yan Nantian, who intended to hand over Lin Xuanzhong some skills, opened the topic again.

"What did General Yan say about this?" The next time, Lin Xuanzhong looked at Master Naluo according to Yan Nantian's meaning.

"The materials of those iron tools are not completely different, and if they are mixed and matched at will, it is like a sick person taking several medicines with the same effect, not only will they not cure the disease, but they may even aggravate the disease. ”

"What does Master Luo mean?"

"Because the material of those scrap iron is different, if the molten iron is mixed together at will, because the cooling rate is different during quenching, it will greatly affect the solidity of the iron wall, so it must be divided into good proportions when using, and the scrap iron used now is distributed in advance according to a certain proportion. ”

"What does Master Luo mean that the molten iron used to pour the iron wall must have a uniform texture?" After talking to Master Luo alone for a while, Lin Xuanzhong came to a guess.

"General Lin is really smart, in fact, although pouring the iron wall is not more difficult than building a high-grade weapon, but due to the huge project, some details cannot be careless, since the old man came forward to help, he naturally doesn't want to cause trouble for you," Maybe Lin Xuanzhong didn't know what it meant to be a refining weapon, but in Master Luo's opinion, Lin Xuanzhong's answer was indeed not wrong.

"General Lin, do you know how many catties of materials are needed to build a six-hundred-meter-long iron wall?" Seeing that Lin Xuanzhong could really understand what Master Luo meant, Yan Nantian couldn't help but ask a question.

"I don't know. ”

"A total of 106,000 jin is needed, General Lin may not know what the concept of 106,000 jin is, but he can tell you that in order to build this iron wall, not only did he consume all the surplus weapons in our army, but also deliberately purchased a large number of iron weapons from the city. Even so, it is barely enough for the construction of strong iron materials. Therefore, in order to make the most of the limited materials, we specially invited Master Luo to help. ”

The reason why he wanted to say this to Lin Xuanzhong was not only that Yan Nantian wanted to tell Lin Xuanzhong how much capital they had invested in building the iron wall, but also that he wanted to praise Master Luo.

"Thank you General Yan for your teaching," Yan Nantian's words surprised Lin Xuanzhong, calculating that so much iron should not be something that ordinary armies can come up with, it can be thought that the loot that the night army has won many times before may have been used to cast iron walls. The more he thought about it, the more Lin Xuanzhong was amazed at the huge investment they had invested in building the iron wall.

"I wonder how thick the iron wall will be?"

"One finger width," replied Master Luo, the so-called one finger width is also calculated based on the available materials. Speaking of which, to deal with such a huge amount of data, only Master Luo, who is extremely experienced in refining weapons, can do it, and there is no one in the Night Army who is good at this.

With a simple gesture of his finger, the thickness of the iron wall constantly reminded Lin Xuanzhong that once it was built, it would definitely be able to withstand the attack of the enemy's siege engines for a long time.

"Then what if the coalition forces don't attack from other positions?" The city wall at his feet was thousands of meters long, and Lin Xuanzhong suddenly thought that the coalition forces might change positions to attack the city when they knew that there was an iron wall, so he immediately asked questions.

"Then they don't have a passage into the city," I don't know why Lin Xuanzhong asked such a non-standard question, looking at the location of the city tower, Yan Nantian replied directly.

"Isn't the marshal going to seal the gates?"

"General Lin, are you a little confused, that city gate is also a passage for our army to enter and exit, how can it be sealed, at most, it will only temporarily add a movable baffle," Lin Xuanzhong's question became more and more substandard, and Yan Nantian, who listened to it, didn't know what Lin Xuanzhong was thinking.

"I see," thinking of their beast attack plan, Yan Nantian's explanation directly made Lin Xuanzhong understand all the problems.

"Master Luo, you might as well accompany us for a walk," Thinking that Lin Xuanzhong was currently in the stage of progress, Yan Nantian no longer cared about some of Lin Xuanzhong's shortcomings in some aspects, and in the blink of an eye, he planned to continue to teach Lin Xuanzhong something.

"Two generals, please," Master Luo smiled, not intending to say anything about the content of the conversation between the two just now, just responding to Yan Nantian briefly.

"General Yan, I see that the weather has changed, which may affect our fortifications!"

"The weather does have a tendency to change, but it is unlikely to rain much in the current season, and in my opinion with Master Luo, we just need to hurry up and build the iron wall as soon as possible. If the weather changes, think about it then. ”

"How long will it take to repair the iron wall?" The three of them continued to walk forward, and Lin Xuanzhong kept asking questions.

"Day and night, it will take about ten days," said Master Luo.

Ten days was exactly what they expected the arrival of the Allied Ordnance Unit, and it was clear that it would take a relatively tight time to complete the entire project. However, reinforcing the city wall is only a remedy after the failure of the beast attack plan, and in fact, it is only used to hide people's eyes, considering that they have spent a lot of time building the iron wall, just to attract the attention of all hostile forces inside and outside the city, Lin Xuanzhong is not worried about the problem of time.

In addition, the reinforcement of the city wall itself has a practical effect, regardless of the beast attack plan, whether it is strengthening the wall or mobilizing reinforcements, it can be called a means to mislead the enemy army, and on the other hand, it can be regarded as a way to improve the chances of victory.

Under Yan Nantian's tactful or direct reminder, Lin Xuanzhong kept thinking through many things. Although hungry, in some ways feasting. As the three of them continued to walk forward, in Shiqiao Village, Xue Yin and the others had already started their busy day.

Xue Yin's medicine furnace is small and easy to operate, but it is also because the medicine furnace is too small, and the amount of medicine that can be refined at a time is limited. If the conditions were better, Xue Yin could actually refine more medicines at once, but now there was no choice.

Yesterday, after confirming that the effect of the medicine was significant, Li Jianran sent some more men to guard around Shiqiao Village, and still strictly forbade any villagers to enter and leave the village, as for all the things that those villagers needed, all the things provided by the night army. Of course, the village itself is self-sufficient, so there is really nothing that needs the help of the Night Army.

All the medicines that were refined yesterday were sent to the barracks overnight, and all of them were turned into powders after processing. In addition to the giant soul incense refined by Xue Yin, after spending a lot of jade, Li Jianran also got some soul incense with more significant medicinal effects from outside, but the amount was not much, and it was only enough to be used by those who infiltrated the coalition camp at a critical time. Anyway, because of Xue Yin's relationship, the problem of medicine has been solved. The next thing is to wait for all the giant soul incense to be refined and the subsequent use of the problem.

Time passed little by little, and by noon, the originally gloomy sky had dissipated, although the sun was still missing, it didn't seem to rain either, and the change in the weather was naturally a good thing for Lin Xuanzhong and them.

One morning in the city was very fruitful, and when he returned to his residence, because he knew more things, Lin Xuanzhong had more problems to consider. News from the outside world still kept coming to Lin Xuanzhong, making Lin Xuanzhong so busy that he didn't have time to practice at all, and even if he had time, he was not in the mood. The current situation has brought great pressure to Lin Xuanzhong, and for Lin Xuanzhong, the unknown future is no longer the source of his pain, and the responsibility is the real key.

In order to ensure the smooth execution of the beast attack plan, that sense of clarity of purpose had made Lin Xuanzhong forget all thoughts of leaving the army. Compared with the previous situation, the current days are really like years, every day makes him extremely tired, but he doesn't dare to stop, Lin Xuanzhong is afraid that once he is lazy, things will go wrong, and then cause irreparable mistakes.

But on the other hand, Lin Xuanzhong was thinking that if he had been tense and couldn't relax, he might not be able to wait for the implementation of the beast attack plan, and he would be tired first.

Two days passed, and two days later, there were only seven days left before the arrival of the allied ordnance unit, and our own reinforcements would arrive in three days. Judging by the current situation, everything is going in a good direction.

On the fourth day, Lin Xuanzhong, who was not overwhelmed by the heavy burden, had almost grasped the situation of all parties, and slowly changed from being pushed by the situation to controlling the situation, and was no longer disturbed by many problems. It can be said that after the ordeal of the past three days, the current Lin Xuanzhong himself has also begun to develop in a good direction, and he no longer needs too much guidance from Zhao Xu and the three main generals, and can already handle some important things independently.

By this evening, all the medicines from Shiqiao Village will be delivered, and by that time all the collection of medicines will be over. Next, their attention will focus on the distribution of ferocious beasts in the mountains.

It had been five or six days since Lin Xuanzhong and Qingyi arrived in Shiqiao Village at the beginning, and now there are signs of increasing fierce beasts in the heavy mountains on the east and west. Because the high-level fierce beasts in the depths of the heavy mountain came out, the ordinary fierce beasts outside naturally continued to spread towards the edge of the mountain range.
