Tang Qi rubbed his sore shoulders and said, "These cups are thermos cups, no matter whether you pour hot water or cold water into them, they can keep warm for a long time!" ”

"Thermos?"

Liu Che picked up a cup quite curiously, and exclaimed while looking at it: "This cup is so exquisitely made, and the material is very different from ordinary materials, could it be a magic weapon produced in Penglai Immortal Island?" ”

Tang Qi rolled his eyes and said, "Can you not pull everything to Penglai Immortal Island?" This is an ordinary thermos cup, the outermost layer is made of stainless steel, and the inside is made of ceramic liners, and you can buy one on the market for seventy or eighty! ”

Liu Che's eyes widened and said, "Is there still stainless steel?" ”

"I'll go, Lao Liu, your focus is strange enough, how many years has stainless steel been out...... Forget it, if you want to pretend to be stupid, there's nothing unusual about this thing, I got five, just one for each of us! ”

Tang Qi said, and pushed the three thermos cups in front of Zhuo Wenjun and the others.

Zhuo Wenjun got the thermos cup and immediately began to observe.

The Zhuo family is a family of iron smelters, and Zhuo Wenjun himself also has a certain understanding of iron smelting.

Zhuo Wenjun is also very curious about the material of stainless steel.

After observing for about half a minute, Zhuo Wenjun couldn't help but ask Tang Qi, "Mr. Tang, the hardness of this stainless steel is many times stronger than ordinary ironware, right?" ”

Tang Qi raised his eyebrows and said: "That's nature, this is also steel!" ”

Zhuo Wenjun suddenly said excitedly: "Then may I ask Mr. Tang, how should this stainless steel be smelted?" Can it be used to make weapons? ”

As soon as these words came out, Liu Che suddenly narrowed his eyes and said with a smile: "Zhuo Ji, do you Zhuo family still have any ideas about weapon manufacturing?" ”

Zhuo Wenjun was stunned for a moment, and then hurriedly waved his hand and said: "No, no, our Zhuo family only makes agricultural tools and iron tools used by the people every day, and has no idea about weapons, please don't misunderstand, Your Majesty!" ”

For the imperial court, it is taboo for people to make weapons privately.

Originally, Liu Che didn't have a very good impression of the Zhuo family, if Liu Che felt that the Zhuo family had bad intentions, then the Zhuo family would definitely be cold and thorough.

Zhuo Wenjun hated that he had no brains just now, and he actually said such a rebellious thing in front of Liu Che, which was so stupid.

"Huh!"

Liu Che chuckled and said, "Don't be nervous, I'm just asking casually!" ”

Zhuo Wenjun smiled dryly: "The merchant girl is not nervous, but she just felt that she was a little unscrupulous, for fear that Your Majesty would misunderstand!" ”

Liu Che nodded, his expression did not change, and he couldn't tell whether he believed it or not.

At this time, Tang Qi said: "Okay, you two don't play each other, aren't you tired!" This stainless steel is indeed hard, but it is not resistant to wear and tear, and it is not suitable for weapons, but it is still very good to make some daily things, and it can be used for a long time! ”

Zhuo Wenjun's eyes suddenly lit up.

The immortals all say that it can be used for a long, long time, and it is estimated that it is more than a hundred years compared to mortals.

Daily utensils that can be used for more than 100 years must be particularly easy to sell.

The smelting method of this stainless steel must be obtained.

Just as Zhuo Wenjun was about to ask, he suddenly seemed to think of something, and said in a different tone: "This stainless steel is really good, but it's a pity that it's not suitable for our Zhuo family!" ”

Tang Qi raised his eyebrows and said, "What's wrong with this?" Aren't your Zhuo family just making daily utensils? ”

Zhuo Wenjun secretly glanced at Liu Che, and then said: "Our Zhuo family does make daily utensils, but if it is made of stainless steel, the utensils will not be broken within a hundred years, and the people will not buy new utensils within a hundred years, which is a huge loss for our Zhuo family!" ”

Tang Qi was dumbfounded!

Tall!

It's a long-term idea!

If Nokia had this awareness, it would have become a leader in the mobile phone industry a long time ago.

"Uh...... Don't talk about stainless steel, Lao Wei, you can get some ice cubes, let's fill the cup with ice water, and then go to work in the field! ”

Tang Qi was about to end the topic and continued to go to the field to collect grain.

Wei Qing said, "Wait a minute, Mr. Tang, what is this stacked thing?" ”

Tang Qi shrugged his shoulders and said, "This is a world map, it's of little use to us for the time being!" ”

"World map?"

Liu Che and Wei Qing exclaimed at the same time.

During this period of time, the two of them listened to Tang Qi's description, and basically knew the general world map, but they didn't expect Tang Qi to take out a serious world map today.

"Mr. Tang, this ...... Can this map be drawn in detail? ”

Liu Che stammered and asked Tang Qi.

Tang Qi nodded and said, "It's quite detailed, anyway, you can basically see the distribution of various countries!" ”

"That'...... Can I open it and take a look?"

Liu Che said, his body began to tremble slightly, obviously excited.

After all, there aren't many opportunities to open your eyes to the world.

Tang Qi said very casually: "You can watch it if you want, you're welcome!" ”

When Liu Che heard this, he immediately beckoned Wei Qing to join him and spread out the map.

Bright colors come out of nowhere.

Deep blues dominate the large space, with lush greens and earthy yellows alternating to fill in the gaps.

Liu Che, Wei Qing, Wei Zifu and Zhuo Wenjun stared at each other at the same time.

The level of detail of the map is beyond their understanding.

The maps of the Han Dynasty were basically drawn on silk or animal skins.

Draw a square here to represent a city.

There are a few curves drawn there, representing the rolling hills.

It's very simple.

But on Tang Qi's map of the world, the plains, rivers, hills and peaks are all clearly visible.

Countless mountains spread across the land, coiling the land like angry dragons.

The rivers crisscross and eventually merge into the vast expanse of deep blue.

It's as if someone is looking down at the world from the sky and then drawing it.

Liu Che couldn't help but glance at Tang Qi.

This world map was taken out by Mr. Tang, could it be that Mr. Tang has been to the sky?

Liu Che was puzzled, but he didn't ask immediately, but continued to look at the map.

At this time, Wei Qing suddenly said excitedly: "Your Majesty, this is Chang'an, it is the Chang'an of our Han Dynasty!" ”

Wei Qing said, pointing to an open plain.

As you can see from the map, the plain is low in the south and high in the north, and there is a large river that spans the north and south.

This river is the Wei River.

In addition to this, there are also some small rivers that flow on the plains.

The so-called eight rivers surround Chang'an, and the location in the center of these rivers is Chang'an, the capital of the Han Dynasty!

As a general of the Han Dynasty, Wei Qing was extremely familiar with the terrain of the Han Dynasty and recognized Chang'an almost at a glance.

Liu Che hurriedly looked in the direction of Wei Qing's finger.

Although Liu Che doesn't know much about the overall terrain of the Han Dynasty, he can barely recognize the topography of his own capital.
