Meng Meng is the best cultivation talent that Qin Yunfei has ever seen, and he even envies this girl's pure nature and her talent against the sky.

Under Qin Yunfei's guidance, Meng Meng learned to simulate thunderclouds step by step, and then produced hydrogen and oxygen.

In addition to food, there are only some shrubs here, and it is very troublesome to make utensils.

However, fortunately, Qin Yunfei was already at the realm of a half-step soul emperor, so he was able to quickly build a basic model.

He used the last of his remaining equipment and began to store hydrogen and oxygen.

Then, redox was carried out to reduce ferric tetroxide, and finally the pure elemental iron was obtained.

It took him an afternoon to complete this process.

And from the next day, he began to repeat, and Meng Meng was on the side to help.

In this way, he completed the work that was supposed to be done in six hours, but he completed it in an hour.

The iron accumulated in this way began to build the furnace.

The steel rolling furnace production will be able to be carried out on about the third day, although it can only produce a few dozen catties at a time, but the key is assisted by star soul power, and their speed can meet Qin Yunfei's initial needs.

In this way, it was another ten days, and on the twentieth day, Qin Yunfei finally produced enough iron.

"Husband, have we all produced so much iron these days?"

When she learned that the stored iron was enough to use, Mengmeng's eyes were shining.

However, Qin Yunfei did not feel any ease.

"Now we have barely completed the first step, and the next step is the forging of the large iron plate, which is the key issue. Although the production process of primary steel is simple, it is very complicated to produce iron armor that can carry people. ”

Qin Yunfei was not blindly arrogant, because he knew that if he wanted to succeed at one time, it was definitely not that simple.

At this moment, Qin Yunfei looked at the other side of the sea.

Sure enough, on the other side of the sea, a fishing boat was coming at this time.

Seeing the person coming, Qin Yunfei's original frowning brows could be regarded as stretching out, "The helper is here!" Mengmeng, in the next few days, we can have a good rest." ”

As he spoke, Qin Yunfei waved towards the fishing boat.

It turned out that Qin Yunfei had an agreement with Princess Long Qi.

Qin Yunfei first did infrastructure construction here, and only after Princess Long Qi sent away her father did she send someone to help her.

It's just that what Qin Yunfei didn't expect was that this Saint King would stay on Pudu Island for twenty days.

And when everyone came, after they landed on the island and saw the production line made by Qin Yunfei, they were all amazed by Qin Yunfei's amazing workmanship.

"Mr. Qin, it's really amazing! It's unheard of to be so calculated!"

"Mr. Qin, where did you learn from, and why have we never heard of such design?"

They had never seen Qin Yunfei's refining method at all, and this Devil Island was a place where thousands of island residents were afraid from the bottom of their hearts. And he actually produced iron essence here.

The so-called iron essence is synonymous with the iron of Gaohe Village.

In general, in some mining areas and ironworks, such high-purity iron products can only be occasionally produced in the process of producing iron products.

However, at this time, which of the iron products in front of everyone was not iron spirit? This was what shocked them the most.

In the past, the production area of hundreds of people only produced a few hundred catties of iron essence a year.

But Qin Yunfei was only twenty days old, and he actually took a woman and produced several tons of iron essence.

These people were amazed, and they already had a deep admiration for Qin Yunfei.

However, Qin Yunfei didn't feel how great this admiration was, but instead smiled bitterly.

"Don't laugh, the work has just begun, and there is still a lot more waiting for us. ”

After that, Qin Yunfei asked these people to start packing up and preparing. A new round of work.

These people can be regarded as first-class blacksmiths in the Purdue Island area.

But after they heard what Qin Yunfei said, none of them understood it at one time.

When they understood, they all admired Qin Yunfei's head, which was comparable to that of a fairy.

"Lord Qin, what a model for us!"

"Lord Qin, if you are in need in the future, as long as you say hello, I will definitely provide you with support free of charge!"

These alchemists were so excited that they couldn't wait to post it upside down to Qin Yunfei.

Qin Yunfei didn't care about these, what he cared about was that he could complete the manufacture of the ironclad ship as soon as possible, so that he could cruise as soon as possible, and he could return to the Longhua Empire as soon as possible.

So, in the next ten days, Qin Yunfei completed the forging of the model through a new refining method such as a new boiler.

After completing the shell of an ironclad ship, Qin Yunfei was very excited.

However, after the completion of the fabrication, the workers were immersed in a brief period of excitement, and then fell into more doubts.

"Lord Qin, this iron armor is so heavy, how can it move forward in the sea water?"

Before Qin Yunfei could explain their doubts, Meng Meng on the side rolled his eyes.

"You people are really stupid! The husband said that whether a boat can float on the water depends on the overall buoyancy, so it does not pay attention to the density of the material itself. ”

Saying that, Meng Meng suddenly hid in Qin Yunfei's arms again, "Hmph, these are all taught to me by my husband!

In an instant, the entire abrasive workshop was full of embarrassment.

Fortunately, Qin Yunfei hurriedly came forward to do a round, which avoided more trouble.

However, these workers also knew the basic elements of sailing, so when faced with this problem, they also fell into contemplation again.

"The hull of this ship is ready, but if the seawater corrodes after launching, and the ship power problem should be solved? ”

Speaking of the troubles they might encounter, they were once again mired in a chaotic discussion.

On the other side, Qin Yunfei was not worried about this problem at all.

"Seawater corrosion is a problem, but as long as we can do a good job of corrosion film covering, then nothing is a problem. And, of course, you don't have to worry about power. If we still use manpower, then what kind of innovation are we having?"

Speaking of power, Qin Yunfei smiled more naturally.

True, he thought of a solution early on.

Although hydrogen is lightweight, it has great problems as a fuel for long-distance transportation.

But in this world, isn't there a more stable baby?

That's right, it's the Star Soul Crystal of the Thunder System.

As long as there is a 100,000-year-old super-large thunder system star soul crystal, it is still very simple to start an iron yacht.

In today's world, the largest treasure ship is only ten tonnage.

If it was to compete with them, the yacht forged by Qin Yunfei would be enough to deal with it.

Set a small goal first, such as remembering in 1 second: book guest residence
