After finishing the business, Tang Ping took the two to Datang for a meal, let them tease their daughter, and entered the palace with maps and photos.

Li Shimin looked at the things handed over by Tang Ping, and couldn't help but sigh: "Tang Ping, with you, I think it's better than a million army!" ”

This is not his second uncle's sycophant slapping his nephew, but really sighing.

Do you think Datang doesn't want to open more mines?

With iron ore, you can produce all kinds of tools, and the army can produce more bows and arrows and armor.

But in ancient times, not to mention mining, it was a problem to find minerals.

At that time, the main way to find minerals was to rely on experience, and there were those with dansha and gold at the bottom. He who has a stone on it has bronze and gold on it. There is a mausoleum stone on the top, and lead, tin, and red copper under it. There is ochre on top, and iron below.

In addition, it is plant prospecting, what grass stems are red, there is lead, grass stems are yellow rust, there are bronze tools under it, there are green onions on the mountain, there is silver under it, etc.

However, these limitations are too great, so I don't know how much it will save to be able to accurately locate the mine to a specific point like Tang Ping.

"Second uncle, I've been to the scene, so I want to go over ......"

"No way!" Li Shimin is really afraid that something will happen to Tang Ping, he was lucky in Baozi City last time, and the sky suddenly cleared, otherwise the consequences are really hard to say.

What he just said about Tang Ping being able to be a million-strong army is not a lie, and if he wants to let Tang Ping out on an adventure again, he won't agree to be the first one.

"But second uncle, although there are a lot of photos here, if you haven't been to the scene, it's hard to find."

"That's not going to work either!" Li Shimin said categorically: "Aren't we able to print?" You make a group of these pictures, and then print out 100 copies, and I send 100 people into the mountains to look for them, and I don't believe that I can't find them. ”

"And I have urgently requisitioned iron ore from all over the country into Chang'an, although the number is not much, but it is more than enough to support your shipbuilding. You're going to have to keep an eye on me at the shipyard. ”

Li Shimin looked at Li Tai, who was reading a book next to him: "Now that Li Tai's gun production is a little slowed down, let Tai'er bring someone over, what do you think?" ”

When Li Tai heard himself, he glanced up at Li Shimin and Tang Ping, then nodded and said, "Okay, I just have some ideas, you can go there and try it." ”

Seeing this, Tang Ping could only nod, although there were drawings, models, and many professional shipbuilders in the shipyard, but after all, their ideas still had limitations many times.

He made some suggestions in the shipyard many times, so that the first ironclad ship under construction was improved both in terms of construction speed and quality.

If he doesn't guard it, even he himself won't be at ease.

And this to find a mine, maybe how long it will take, if it is fast, it will take two or three months to go back and forth, and the shipbuilding side really can't afford to delay, anyway, the improved guns and cannons on Li Tai's side are finalized, even if he is not there, the craftsmen below can also be built according to the gourd painting scoop.

handed over all the photos and some records at that time to Li Tai, and asked him to take people to look for mines, and the iron ore that Tang Ping requisitioned and transferred in a few days was in place.

He also returned to shipbuilding.

"Hapahapa ......"

"Oh, our good Tang Tang, you're here to pick up your dad again?"

Tang Ping took off his gloves, washed his hands with water and soap on the side, and dried them before carefully picking up Tang Tang.

Every day, when Tang Ping's work in the shipyard was about to end, Tang Tang would follow the car to pick up Tang Ping.

Tang Tang, who has been six months old, already knows how to wave his hand and consciously utter some syllables.

Anyway, every time she raised her hand and shouted Hapahapa to Tang Ping, Tang Ping felt that she was calling her father.

"Is this already going to be built?" Wang Qingluan looked at the behemoth in front of him and asked with some excitement.

"Nope!" Tang Ping shook his head and said: "This is only the hull is about to be completed, but there are still many internal structures in the cabin that have not been completed, and it is almost more than two months away from being fully completed." ”

In the past four months, the craftsmen have worked in several shifts day and night, and now the hull of the ironclad ship, tentatively named Jiaolong, has finally been almost built.

The steel used for the hull is not ordinary steel, strictly speaking, it is already an alloy steel, and when it is smelted, chromium bought by Tang Ping from Hyundai, as well as aluminum and copper.

This is the closest seawater steel that Tang Ping asked Gou Shaoqun to consult some smelting experts in modern times, and came up with the closest seawater steel that can be made in Datang.

It can be said that the smelting process of the entire Datang Dynasty has produced so many of these chromium alloy steels in four months.

Tang Ping walked to the side of the hull and tapped it with his fingers, and there was a silent metallic sound, which was also Tang Tang's favorite, and he was directly amused by Tang Ping and giggled.

"When the cabins inside are finished, we will conduct a test voyage, and if there are no problems, we will add new guns to them." Tang Ping pointed to the wooden box on the side: "This is a new type of artillery sent from the arsenal, specially equipped for this Jiaolong, a total of thirty-two." ”

These are the latest imitation Franji guns, each cannon is equipped with seven shell bays, and can be fired once in about two minutes in actual combat.

Although there are many drawbacks such as airtightness and range, in this era, this is definitely an unbeatable weapon.

Coupled with the use of steam power, as well as the smaller hull and flexible steering, the Jiaolong is used to fight the current East Vietnamese naval forces, and the distance will be opened immediately after a salvo, and the kite can sink the giant ships that the East Vietnamese naval forces now dominate the East China Sea in two or three rounds.

Tang Ping knew that Wang Qingluan had been waiting to attack Dongyue, and this Jiaolong was carrying this hope, so every time Wang Qingluan brought Tang Tang to pick him up, he would give her a rough introduction to the progress of the current work.

Returning to the convenience store with his daughter-in-law and children, Tang Ping stretched his waist and was about to eat, when Li Yuanji suddenly rushed in.

looked at Tang Ping with a panicked face and said, "Brother Ping, something is wrong." ”
