Zhang Nan walked in and found that Li Er was still dressed as he left. He was wearing white clothes and his Panlong Sword was still on his hand.

When Li Er saw Zhang Nan coming in, he picked up the tea cup and took a sip of tea and said, "Why are you here again? Didn't I ask you to run to that boat?"

After hearing Li Er's impatient question, Zhang Nan rolled his eyes in his heart and said, "You think I am willing to come to find you." But he still honestly bowed to Li Er and Empress Changsun.

"Your Majesty, the matter of this ship is already settled. Now, as long as you give the order, you can start building a ship." Zhang Nan said.

"Oh? It's so fast, it's a bit beyond my expectations. But didn't I say that, wouldn't it be enough to just go to Wei Tianwu to discuss the shipbuilding matter? If you have no money, go to your father-in-law." Li Er continued to drink tea, and even Zhang Nan didn't even look at it.

Looking at Li Er's unhappy appearance, Zhang Nan felt that it was very likely that he had ruined Comrade Li Er's good deeds that led to Comrade Li Er's dissatisfaction in front of him.

"The problem lies in this shipbuilding. Our Chang'an City cannot build such a large ship, so we can only go to the docks on the beach to build ships, and a large number of skilled craftsmen are needed." Zhang Nan scratched his head and said.

"Can't build such a big ship? How could it be? What did Wei Tianwu eat?" Li Er obviously didn't believe that the Ministry of Works, which was directly under his jurisdiction, dared to say such things.

In Li Er's opinion, let alone one ship, even one hundred ships. As long as he gives orders, the Ministry of Works must build it for him.

Seeing Li Er's irritable look here, Zhang Nan began to explain to Li Er. After explaining for a long time, Li Er finally understood the reason.

"What do you mean is that you want to build a thirty-foot boat?" Li Er said to Zhang Nan.

"Nothing is wrong." Zhang Nan said with a look of course.

"Do you know now that I know how big the largest ship is?" Li Er continued to ask.

"I really don't know this, but you know, your lord, how big is the largest ship?" Zhang Nan asked back.

When Li Er heard Zhang Nan ask this, he knew that Zhang Nan was not holding back his weight, but was preparing to let him experience the feeling of a mountain cannon. So Li Er was wisely not talking, but began to stare at Zhang Nan.

The atmosphere inside the house was very awkward. In the end, Empress Changsun came out to smooth things over and said.

"Okay, Qingquan, the thirty-foot-long ship you mentioned is really a bit too long?" Queen Changsun asked. After all, the largest ship she had ever seen was Emperor Yang of Sui's dragon ship. In the eyes of Queen Changsun, that was already the largest. Now Zhang Nan's mouth is thirty-foot-long, and Queen Changsun also felt it was a bit unrealistic.

"Actually, it's not big at all. After all, we go out to pull things, not to go out for fun. Your Majesty, you have to think clearly that the bigger the ship is built, the more things we can pull to our Tang Dynasty. Moreover, our ship does not require manpower. It burns coal. In order to ensure the sailing of the ship, we have to bring a lot of coal." Zhang Nan explained.

After hearing Zhang Nan's explanation, Li Er pinched his chin and started to think.

In fact, if you really don’t care about manpower and material resources, you can create something even if you grow a little longer.

The size Zhang Nan took out is not empty-mouthed, after all, there are precedents, although this example is an example of the Ming Dynasty.

Zheng He's voyage to the West can be said to be the largest sea navigation in China and even the world in ancient times, with the largest ships, the largest ships, the most seamen, and the longest time. It was decades earlier than the sailing time of European countries.

Although Zheng He took a boat of things to spread money and showed his power to the distant countries, it is undeniable that its scale is indeed very large. In terms of size, a single-ship is enough to stand out for the heroes.

What is the biggest ship, the "treasure ship", what is the great magic?

Among Zheng He's fleet of voyages to the West, there were five types of ships, namely treasure ships, horse ships, grain ships, boats and warships, among which treasure ships were the largest.

According to the "History of Ming Dynasty: Biography of Zheng He", Zheng He's fleet had a total of about 240 ships, including 63 treasure ships, the largest one was 44 zhang long and 18 zhang wide. It is equivalent to the current length of 150 meters and 60 meters wide, making it the largest sea ship in the world at that time.

The ship has four floors, and there are nine masts on the ship that can hang twelve sails. The anchor weighs several thousand kilograms. It takes 200 people to set sail. A ship can accommodate more than 1,000 people, and its load capacity is even more than 800 tons. It can be said that it is a majestic and unparalleled.

So now Zhang Nan takes out a thirty-foot boat, and Zhang Nan thinks it’s really not big, especially for people like Zhang Nan who live in an era with an aircraft carrier. A ship that is more than 100 meters long is really not enough to see.

"That means that this ship must be built at the docks by the sea, right?" Li Er asked.

"That's right. We build steam engines in Chang'an City and ships on the beach. Then we can pull the steam engine over and assemble it." Zhang Nan said.

"Okay, I agree. I will write an order now to let local officials cooperate in the construction of ships. Well, Qingquan, you can supervise the construction." After Li Er said that, he pointed at Zhang Nan.

"Ah? Are you going to supervise the creation? I thought you just need someone to go there, yourselves," Zhang Nan asked, pointing to his nose.

"Who else can you do? They don't know more about the ship if you send others to you. Besides, if you go this time, don't go on land, just take a hot air balloon. I think this shouldn't be slow, you can come back at any time." Li Er said.

Zhang Nan was reminded by Li Er that the Tang Dynasty is different from before. The Tang Dynasty now has hot air balloons. Although the road seems far away, if it wants to fly from the sky, it will not take long, at least it will be much faster than riding a carriage.

"Then I will go, but I will take a few people there. And you can't let me take this hot air balloon myself, I want the hot air balloons there." Zhang Nan quickly explained his request in advance.

Otherwise, it would be a thank you if you run around and then stick three or four hot air balloons to Li Er. Zhang Nan would definitely not do the loss-making business.

Li Er glanced at Zhang Nan, then waved his hand. This time he waved two meanings. One was that he agreed, and the other was that he wanted Zhang Nan to get out quickly and not be upset in front of his eyes anymore.

When Zhang Nan saw Li Er agreeing, he bowed and began to prepare for his business trip.
