Shen Qingqian's heart blossomed, but his face was very reluctant, "I don't have gold leaves, only gold melon seeds, like this, you or?" ”

With the action of picking out his sleeve pockets, Shen Qingqian took a few golden melon seeds from the system warehouse.

When Uncle Huhu saw that she really had gold, his attitude became a little more enthusiastic, and he took out a handful of guns out of nowhere, "How much does this one weigh you?" ”

It is a scale specially used by the ancients to weigh gold, silver and precious Chinese medicine, with extremely high precision.

Many people may have a misunderstanding that the ancient currency was copper plate, silver ingot, gold ingot, etc., but in the actual transaction process, copper plate is the most used.

Due to low productivity, gold and silver mining is limited, and silver ingots and ingots are not used much in normal times, but there is a lot of broken silver.

After all, it is too heavy to carry a copper plate, and it is better to exchange it for silver than to exchange it for silver.

Gold and silver are valuables, and they need to be weighed with high precision, and they can be accurate to centimeters, that is, milligrams.

Shen Qingqian handed one over, and Uncle Huhu hurriedly weighed it, and his eyes brightened even brighter, "There are two baht!" ”

The baht of the Great Jin Dynasty is equivalent to the Tang Dynasty in Shen Qingqian's world, one baht is about 1.55 grams, and two baht is three grams.

Half a gold leaf is about fifteen grams, that is, it takes five golden melon seeds to buy a telescope.

Shen Qingqian thought for a while, pointed to the pattern on the golden melon seeds, and gestured to four, "Four at most, otherwise I won't want it." ”

In addition to the points, the most given are golden melon seeds and silver peanuts, but these are all hard currency, Shen Qingqian will not spend it easily, and of course he has to talk about the price if he can bargain.

Uncle Huhu understood what she meant, and his face was suddenly full of pain, and he gestured and said, "Four, plus five hundred Wen!" ”

Shen Qingqian shook his head, "At most, four plus two hundred Wen." ”

Uncle Hu's face was full of pain, and he clutched the binoculars tightly, hesitating whether to sell it at this price.

Shen Qingqian saw him like this, and made a gesture to leave, but he was stopped by shouting as soon as he took two steps.

"Deal!" Uncle Hu felt that his heart was dripping blood, but in order to return to his hometown as soon as possible, he had to endure the pain of parting his love.

Shen Qingqian immediately handed over the money with a smile and went to take the telescope in his hand with the other.

For fear that this person would regret it, Shen Qingqian took the telescope and the beaker that came with it and quickly got into the crowd, turning several stalls before stopping.

"Sixth girl, what's the benefit of this thing?" Ling Yun asked curiously.

Shen Qingqian handed him the thing, with a hint of pride on his little face, "Take a look for yourself." ”

Ling Yun picked it up and looked at it, but he didn't find anything, didn't he just magnify something on the ground.

Shen Qingqian reminded: "Look in the distance. ”

Ling Yun did as he was told, and then his eyes widened suddenly, "This ...... This thing ......."

With his eyesight, he can see thirty zhang away without this thing, and after using this thing, good guy, the eaves on the roof of the restaurant seventy zhang away can be seen clearly!

If this is to be used when marching into battle...... Ling Yun couldn't imagine it.

Shen Qing nodded with a smile, and then made a "shhh" gesture.

In the time that followed, Ling Yun's attention was completely focused on the telescope, so much so that he gave Shen Qingqian a chance to cheat.

While he was not paying attention, he unknowingly held all the classics such as "Primary Planting", "Basic Construction", "Basic Tool Making" and so on.

When Ling Yun came back to his senses, he saw Shen Qingqian holding a bunch of things in his arms, most of them were books, he hurriedly reached out, "Give it to me." ”
