Once the problem is found, it is much easier to solve.

Although the situation is not as simple as Liu Zong's mouth, it is no longer something difficult to solve.

After sorting out his thoughts, Yanagi began to make the final step of transforming the almost finished warship that had been cast.

Finally, mark every position that needs to be inlaid with zinc plates, find the deputy and others, and order: "Inlay these positions that I have marked, inlay zinc plates, and this warship is finished!" ”

The deputy who was pulled by Liu Zong directly from his sleep in a daze was full of excitement when he heard this, and even most of his sleepiness dissipated.

Due to the new task assigned by Li Feng, everyone was on standby in the shipbuilding base at any time, preparing materials, constructing the basic hull, and casting on many large surfaces.

After all, if you really wait until Liu Zong studies the drawings thoroughly, finds out the mistakes and omissions before casting, it will definitely be too late in time.

Because they all know that sometimes it's just a small problem, and the time spent is not necessarily short.

Therefore, in advance, the parts that are completely sure that there are no problems are cast, and finally find the problems and then cast and merge the parts that may have problems, so as to save enough time and complete the tasks assigned by the lord within the time limit.

Unexpectedly, in less than half a day, Liu Zong suddenly called them over and announced that the problem had been solved.

The deputy looked at Liu Zong suspiciously, "Master, you're not joking, are you?" Really solved? The problem of corrosion of parts, we have been stagnant for a long time! ”

"Hey, don't believe me? Then I'll let you see, your boss is your boss after all! ”

Liu Zong put the drawings given by Li Feng in front of everyone, and then pointed to a few words inlaid with zinc plates and annotations on them and said, "See, this is what we ignored." ”

"I don't know exactly what it is for the time being, but if there is any difference between the ship we built and the drawings, that's all that's left."

"If there is still a problem, it is definitely not our problem, it is a problem with this drawing!"

Liu Zong's sworn appearance made everyone look at each other, and the deputy said dryly: "Master, isn't this too risky, isn't this a gamble, if there is really a problem, the lord will definitely cut off everyone's heads." ”

Liu Zong waved his hand and said, "You can do it boldly and boldly, the lord, I will naturally go to clarify the current situation, or do you have other methods?" ”

"If you can't make something in a week, you will be beheaded, and even if there is a problem if you make it, won't it make everyone live for a while longer."

A drop of cold sweat rolled down from the deputy's forehead, you wooden, this pure and pure forced Liangshan, you can't do it, right?

The deputy smiled bitterly and said, "Yes, master." ”

Liu Zong patted him on the shoulder meaningfully, "Do it well, I'm optimistic about you, hmm...... I'm sleepy, I'll go rest for a while, and I'll have to go to the lord tomorrow morning to tell you." ”

"And why do you want to inlay those zinc plates on Iron Boat Mountain, I always have a hunch that I will get the answer I want from the lord."

Liu Zong solved the problem and went to rest, but the others in the shipbuilding base were destined to sleepless.

Whoever told Liu Zong to leave threw down a large pile of drawings to them, and they needed to familiarize themselves with the corresponding drawings in the shortest possible time, and then immediately began to cast the finished iron cavalry warship with all their might.

This night, Liu Zong slept very soundly, because the things that had bothered her for a long time finally disappeared, and even when she got up the next day, she felt refreshed, as if all the depression had dissipated.

Subsequently, Liu Zong went to the City Lord's Mansion with the original drawings, found Li Feng, and asked himself that very curious question.

"Your Lord."

"Huh? Master Yanagi Zong, is there something going on? If it's material manpower or something, you can use the warrant I gave, could it be that Master Liu Zong has other important things? ”

Li Feng looked at Liu Zong suspiciously, his eyes were very surprised, as if to say, "Oh, you still have time to come to me, it can't be that the tasks arranged are not enough, right?" ”

"Uhhaha, there are indeed other things to ask the lord for help, and it comes from the drawings."

"Is there something wrong with the drawings? It shouldn't be......" Li Feng touched his chin and looked at Liu Zong suspiciously.

"You probably found out that you said something big and wanted me to take back my life, right?"

"Oh no, no, no!" Liu Zong hurriedly waved his hand.

Just kidding, what is the status of the lord, if it is replaced by any dynasty, that is the emperor.

If you want the emperor to take back his words, I'm afraid that it is not sincere to seek death, and it belongs to the kind that it is difficult for the emperor to refuse.

Although Li Feng is definitely not so cruel and directly beheads and exterminates the clan, for the sake of the majesty of the lord, he must be punished heavily.

Liu Zong hurriedly put the drawings in front of Li Feng, then pointed to the position where the zinc plates were inlaid, and asked, "Lord Lord, I want to ask why these zinc plates are inlaid on the iron ship, and what are the mysteries in this." ”

"Oh~ So you're here to ask a question, so it's easy to say, wait, this shouldn't be the flaw you said, right?" Li Feng said suddenly.

Liu Zong nodded slightly embarrassed, as the first shipbuilding master of the territory, but he still had to trouble the lord, which really made him a little ashamed.

However, if this question is not clarified, his heart is like a hundred claws scratching his heart, and he is very uneasy.

And from top to bottom in the territory, almost all of them have been directly or indirectly inspired by the lord, so thinking about it, it doesn't seem to be a big deal for him to come and ask for advice in person.

Liu Zong said: "Yes, I ignored this point when I was building ships before, which made the iron cavalry warship defective, but now it has been solved, but I still can't figure out the principle, so I want to ask the lord what he thinks." ”

"Oh, that's right." Li Feng glanced at Liu Zong meaningfully and saw his careful thoughts.

Yanagi was not sure whether the defect was caused by the absence of inlaid zinc plates, because Yanagi did not know whether the purpose of the zinc plates was to eliminate the defects or whether they were merely used for decoration.

But as long as Li Feng can answer this question, Liu Zong will naturally know whether the defect is caused by the zinc plate.

If it was, everyone would be happy, but if not, Liu Zong also indirectly showed that the flaws were difficult, and it might be difficult to complete the task in the end.

This old fritter approach can't be said to be wrong, but it's a way to protect yourself.

Li Feng didn't plan to debunk or punish anything, as long as he could do his best to contribute to the territory, then there was no need to be too harsh, otherwise it would only make everyone centrifugal.

Li Feng touched his chin and said in a deep voice: "If you really want to understand this problem and figure out the specific principle of it, maybe I may not be able to finish it for three days and three nights, but if you just want to know the role played by the zinc plate, just as a specific case analysis, I can quickly explain it to you." ”

"Well, in this case, I'll tell you the story of iron and zinc first, and as for the rest of the things, you can take this thing back and study it yourself, and if you can make a little name for it, I can just give you a task."

Liu Zong took a strange name book called the first solution of chemistry in Li Feng's hand with a puzzled face, opened it and looked at it twice, except for the words of iron and zinc inside, he knew that those strange symbols and reactions could be understood, but when they were put together, they were completely confused, what did they say?

Li Feng coughed twice: "Na, don't worry, you can just go back and watch it slowly, hmm, let's continue the story of iron and zinc." ”

"First of all, you have to know that there is a concept called metal activity, which is ranked from strong to weak as potassium, calcium and sodium......"

"Then, according to this order, zinc is in front of iron, so in seawater, when the two are together, zinc can play a good role in protecting iron from being corroded by seawater."

"As for more things, you can continue to learn about them in the trees, but that's too much to say."

Li Feng spread his hands and showed an expression of such a simple thing towards Liu Zong, who was stupid.

This is not to blame Liu Zong for listening stupidly, after all, there was no step-by-step process before this, and it was difficult to figure out the knowledge in it if he jumped directly to this step.

However, Li Feng believes that the brains of these backbones in Fenglin Town, if they study hard and have their own "teaching materials", the teachers of chemistry probably don't have to worry.

Besides, even if Liu Zong can't do it, if there are not a few Tie Lao Wu, they can't miss this course.

If you want to build sharper and more powerful weapons, if you want to grow better and more food, if you want to forge stronger walled houses, chemistry, this is a must!

So as soon as Li Feng spread out his hands, he conjured up a pile of books in his hands and piled them up in front of Liu Zong.

"Oh, by the way, and these, you should all be able to use them, take them and divide them yourself, it's good for you to understand, and in addition, it's also about a task I'll give you in the future."

"Okay, now that I've said it, if Master Liu Zong has nothing else to do, let's go back and study it carefully, I'm looking forward to your results."

After Li Feng finished speaking, he ordered to give it away, and after Liu Zong walked out of the City Lord's Mansion in a daze, he suddenly came back to his senses, his eyes were dull, and his mind seemed to have countless tadpole Xiaowen scurrying around, and he had a headache worse than the wordless heavenly book.

Liu Zong couldn't help but want to wail, oh my God, what the hell is this!

Then he glanced at the many books in his arms, and the upper half of his face was hidden in the shadows, and let out a terrifying laugh: "Hey, hey, hahaha, of course everyone has to share good things." ”

"The lord has said that this is a treasure for us, of course, no one is missing."

And Tie Lao Wu and the others, who were trying to contribute to the territory, suddenly shivered all over their bodies, and an inexplicable uneasiness and coldness enveloped their bodies, as if something bad was about to happen......
