You must know that the mountains, forests and rivers in the Han Dynasty are now owned by the imperial court, except for those owned by private individuals. The locations of these ores are all state-owned, and of course Lin Qingliang cannot monopolize them privately.

Returning to the Xuanfu Embassy, Li Yi immediately began to draw the style drawings of the crucible kiln, as well as the selection and firing process of various production materials. In such a hurry to make glass, of course, there are also unavoidable hardships.

Now Lin Qingliang is investing everywhere, and the funds are also stretched, and the stock of funds in the government is not much better, and the construction funds of the 'Xiangshui Dam Reservoir' in charge of Guang Lin Jin are gone, and if we do not expand the source of funds quickly, I am afraid that many projects benefiting the people will be suspended.

However, although Li Yi graduated from the bioengineering major, he has only heard of the technical methods of firing glass, at most he knows some technological processes, but he has never practiced it himself, and can only rely on his previous shallow memory to make this simple process and the pattern of the crucible kiln for firing glass, and the other so-called practical exploration will all depend on Lin Qingliang.

Early the next morning, Lin Qingliang rushed to the Xuanfu Embassy. He came this time to let Li Yi go with him to see those quartz stone mines, so as to select the most suitable materials to refine the glass.

Looking at his anxious appearance, Li Yi didn't even have the qualifications to hesitate a little. Damn, the current Lin Qingliang, if he has any difficult and miscellaneous things, he is all looking for himself, and in his mind, he has regarded himself as an omnipotent all-powerful god.

Even if Li Yi has a big matter, he has to put it down and wait for him first, otherwise, he doesn't know how to slander it in his heart!

However, for Lin Qingliang's enthusiastic invitation, Li Yi also has his own ideas. Lin Qingliang said that these quartz sand, if it is really of good quality, and then select the best quality fluorite together, maybe you can fire a lens that meets the optical standards, and at that time, it will not be a problem to make many telescopes.

Once there is a telescope, the army is like having clairvoyance, in this era of cold weapons, the advantage is very obvious, and the combat effectiveness will be doubled!

However, the due date of delivery is just in the last two days, and Li Yi is really relieved to go. However, after thinking about it, in order to confirm the glass materials as soon as possible, let Lin Qingliang start work in time, and for the future development of Yunnan, Li Yi can't care so much, not to mention, it seems that there is no sign of giving birth until now, and at most he will rush back in the afternoon, so he should not delay anything.

After explaining the affairs of the house to Lin Yi and others, and going to visit Wan Ru again, seeing that she was still smiling, and had not felt the slightest discomfort, Li Yi relaxed his mind slightly, and after instructing Caifeng and Caidie, Li Yi handed over the information written by staying up all night last night to Lin Qingliang, and then with him, with Lian Jun and dozens of other personal soldiers, he went on the road again.

The quartz mine site mentioned by Lin Qingliang is at the northeast foot of Zhongling Mountain, four or five miles away from the official road, but it is not far from Hengshan where fluorite and feldspar were found, and it is only a dozen miles away from two miles. Moreover, there are many pedestrians here, and it is the main road to bypass Wumeng Mountain in addition to the official road.

The group of people galloped quickly, but in an hour or so, they rushed to the vicinity of the sand slope ditch that Lin Qingliang said, and saw from a distance that on the hillside in front of them, a milky white translucent rock was exposed in pieces, and it was everywhere on the mountain, which was very eye-catching.

Everyone dismounted and walked, and soon came to the top of the hillside, Li Yi looked around, and found that this milky white rock area covered a very large area, along the slopes on both sides of the road until the bottom of the ditch, there seemed to be similar stones on the left and near the mountains, it seems that the reserves of this quartz ore are enough.

Li Yi leaned down, took out a small hammer and knocked down a piece of quartz stone to observe carefully, relying on the samples he had seen in the laboratory before to compare, and found that the quality of these quartz stones is still quite good, if the requirements are not high, the lenses for making telescopes are also available.

And this is only the bare part of the rock, which has been weathered in the sun and rain, and if you dig deeper, there may be more high-quality varieties suitable for firing lenses.

Li Yi, Lin Qingliang and others walked roughly along this hillside, learned about the geological structure in detail, and found that there were many feldspar, limestone and other minerals associated with quartz stone, which made Li Yi excited again.

Several kinds of minerals for firing glass can be found here, and there is no need to search around, plus those high-quality fluorite in Hengshan, once the glass is fired, how can the rough quality glass imported from overseas be compared with it! Isn't Yunnan unique in glass production in the future? It's all money!

Full of joy, Li Yi and Lin Qingliang eagerly chatted about the process of glass making in the future.

Li Yi also told Lin Qingliang in detail about the production method and process he knew, and instructed him to explore on this basis and make high-quality glass as soon as possible, so as to reduce the economic pressure on Yunnan.

When the future industrial blueprint was depicted and the intention was still unfinished, I found that it was already three or four o'clock in the afternoon.

Everyone was in a very good mood on the way back, and finding such a large mineral deposit is equivalent to finding a treasure for Yunnan, which is an inexhaustible source of income, and there is no need to worry about financial constraints for decades.

Li Yi and his entourage walked out of the mountain trail, and soon after turning onto the official road, they heard the Luan bell ringing, and two fast horses came behind them, and they quickly rushed behind them.

Seeing that many of his own soldiers had strengthened the guard, Li Yizheng didn't care, and a delicate sound sounded in his ears, and suddenly two snow-white horses galloped to his side.

Li Yi turned his eyes and saw that the passenger on the horse in front of him was covered with frost, and he was squinting at himself coldly, but it was not Yang Caiying, the princess of the Great Yi Ning Kingdom, who was it, and she was followed by the Zhan Aya, who was good at light body kung fu.

Li Yi reined in the head of the horse of the 'Night Lion', slowly stood on the spot, and said with a slight smile: "It turned out that the princess was coming, Li Yi really felt honored, and asked Her Royal Highness the princess not to blame her for being hasty and rude!" ”

Yang Caiying's eyes widened angrily, her willow eyebrows were upside down, and her cold eyes looked at Li Yi coldly, with a look that she didn't share with him.

Hehe! It's no wonder that she just rejected Dayi Ningguo's marriage proposal yesterday, and Yang Caiying rushed over today, what is this not Xingshi's question.
