Tomorrow is 515, the anniversary of the starting point, and the day with the most benefits. In addition to the gift bag and school bag, this time's "515 Red Envelope Flip" must be seen, how can there be a reason not to grab the red envelope, set the alarm clock high~

The Lu family's cargo ship was loaded with silk and porcelain!

Li Ling had a feeling of enlightenment, why not use porcelain to do a mold experiment? Porcelain is not only very resistant to high temperatures, but also has strong plasticity, which is really a good material for molds.

It occurred to him that he should be able to solve this problem if he used two hollow cylinders nested on top of each other.

"How do you find porcelain that meets your requirements?" Li Ling made a mistake again, at least he couldn't make such porcelain.

"Young master, you don't have to worry about this, there must be more porcelain craftsmen here than craftsmen who know how to build ships!" Ma Qiang said with an oath.

Since ancient times, maritime trade has been developed here, and it is natural to be able to produce porcelain and the like, and although the imperial court forbade the sea, it did not prevent porcelain from circulating in the interior. There are still many people in the firing ceramics industry.

Their techniques have also been passed down from their ancestors, and it shouldn't be difficult to find the right ceramic products.

"Young Master, I know that the old Wang Tou's technique at the head of the village is the best in ten miles and eight villages, but he is old and has not done it for many years!" After all, he has been fishing here for a long time, and he still knows the basic situation in the fishing village.

Lao Wang is over the age of sixties, has no children and no daughters under his knees, and usually lives with a few of his apprentices.

"Li Gongzi, your request is very simple, you don't need the old man to make a move, my few disciples who don't take advantage of the opportunity can come easily!" The old king said proudly, very confident in his apprentice.

Li Ling built these warships to resist the pirates and protect the safety of the party, and if there was anything to help, he and his apprentices would definitely do their best to help the other party.

"Old man, can you polish the two concave surfaces as smooth as possible?"

If the mold is very flat in several planes, there will be a lot less trouble in the future.

"No problem, let's try to be as neat as possible!". The old king had not yet agreed, and a young man about thirty years old agreed in place of the master.

He is the eldest apprentice of Wang Lao. Responsible for the manufacture of the mold this time, Li Jieyuan explained that he must be cautious.

When the hollow cylinders were made, Li Ling was overjoyed, their surfaces were really decorated very neatly.

"Young Master, just take a look, I'll take care of the rest!" Ma Qiang said excitedly.

It was a privilege for him to be able to verify a craft that he had never touched before.

The boiling molten iron is gradually poured into the mold, slowly filling the voids in it.

Li Ling and Ma Qiang were both excited, it was really possible to succeed!

Ma Qiang's hands trembled a little, the sweat on his face fell down in big drops, and he carefully poured molten iron into it.

"Bang".

With a bang, the sound of porcelain breaking fell short.

"Young Master, this time it was me who was careless."

Ma Qiang was a little annoyed, if he was more careful, he might be able to succeed.

"It's okay, let's do it!". Li Ling comforted that any kind of attempt and innovation cannot be smooth sailing.

Another set of molds was lifted, and Ma Qiang was full of ambition and began to pour molten iron into it.

"Slow down, slow down!". Ma Qiang kept warning himself in his heart that he must not let Li Ling and the others down.

"Bang".

The sound of porcelain breaking again, and he missed again.

The handyman silently changed another set of molds and left silently.

Several times in a row, Ma Qiang did not succeed, and he was a little overwhelmed.

"It doesn't matter, try it a few more times, it will always work!" Li Ling continued to comfort.

Ma Qiang nodded, tried again and again, and poured molten iron into the mold little by little.

Finally it worked. Molten iron fills the gaps in the mold.

Ma Qiang wiped the sweat from his head and waited confidently for the molten iron to cool. After the two layers of porcelain were shattered, what was left was a bright barrel.

The whole zhang is completely integrated into one, and there is no trace of embedding.

"Master, we succeeded!". Ma Qiang shouted happily, he finally helped Li Ling do something.

The old man Wang in the distance smiled and nodded, leaving a few apprentices to serve here and left.

Ma Qiang was excited, and he began to carefully polish the cannon body. Little by little, I began to repair my own works.

Andre didn't believe that Li Ling and a small blacksmith could refine a more sophisticated cannon barrel, but he took a closer look and found that there was no other achievement except for lifting scrap molds from the blacksmith shop, so he didn't pay attention to the other party.

"Father, this is Lu Yun and Lu Gongzi, the owner of more than a dozen merchant ships on the sea!" Antonio led a handsome teenager into his home and introduced him to Andre.

"Oh, disrespect, disrespect." André greeted Lu Yun in Chinese, which was not very proficient.

As early as when he was in Dongying, he had heard of the power of the Lu family, which almost monopolized the maritime trade between the two countries, and was an ancient and powerful family.

Andrea's face was different, Lu Yun was naturally very happy in his eyes, although the Lu family was not very famous in the Ming Dynasty, but it enjoyed a good reputation overseas.

When it comes to the Ming Kingdom, the first thing that comes to mind must be the Lu family, who occupied the sea trade routes, and it is said that their family was connected to the shogunate and many daimyos. The power is not trivial.

"Andrea, you must already know my identity, my family is very interested in the 06 gun you made, I wonder if we can talk?". Lu Yun asked confidently.

Li Ling now only has the identity of Xie Yuan, and he does not even have a formal official position. As long as Andrew has a little vision, he should know how to choose.

"Master Lu, what can I do for you, and what can you give me?" Andre asked eagerly. Compared with the two, he still felt that the Lu family was stronger.

"Money, beautiful women, and even an official position in the Ming Dynasty, as long as it is a local position, our Lu family should be able to satisfy you! All you need to do is keep making more powerful firearms for us, and of course, if you can hand over the firearms manufacturing blueprints in your hand, even better! ”。 Lu Yun replied without hesitation, these conditions were all decided by the Lu family after careful consideration, and he was very confident that Andrew would be able to agree to his conditions.

"Money, beautiful women, official positions!". Andre's breathing accelerated, wasn't all this what he dreamed of, as long as he had these, he could return home.

It's just that when it comes to handing over the casting drawings of the Franc cannon, he is a little hesitant, this is killing chickens and taking eggs! "Father, why don't we think about it first and reply to Lu Gongzi later!" Antonio was also not in favor of immediately agreeing to Lu Yun.

It is better to leave room for everything.
