The specific use of coke, Li Yuanjia didn't talk to Fang Fengzhu in detail, but just told her that this thing burned longer and the temperature was higher.

For a lady in the Zhenguan period, Fang Fengzhu was naturally at a loss for this.

However, after seeing that Li Yuanjia seemed unwilling to elaborate, Princess Han no longer asked, but silently memorized the word coke in her heart.

didn't care too much about Fang Fengzhu's thoughts, Li Yuanjia directly summoned the person sent by his younger brother to deliver things, and then ordered: "After I go back, let King Xu continue to make more coke, and then transport it all to Chang'an...... Don't be afraid to spend money! The things I left in Luzhou, so that he can use them at will, and he must make me more coke! ”

When he said this, Li Yuanjia hesitated for a moment before continuing: "In addition, next time you come, send me a craftsman who can make coke!" ”

"Yes, King!"

Regarding Li Yuanjia's order, the person who came naturally agreed respectfully.

Before being sent to Chang'an by Li Lingkui, of course, he had received orders from his own king, and he was very clear about the status of this Han king in Li Lingkui's mind. Moreover, they left so many industries to King Xu in Luzhou, and even a huge amount of land, so it is natural to make some coke.

It's just that he really can't understand the use of this coke.

After explaining clearly and letting this person retreat, Li Yuanjia excitedly circled around several boxes, and the excitement in his heart could not be calmed down.

The application of coke in ironmaking is, of course, not so simple.

Let's not talk about the difficulty of producing this coke, I heard that those craftsmen spent more than ten days to produce more than 100 catties, and the high cost was scary.

Iron and steel making is a system, and coke alone may not be immediately usable.

"So, build an iron-making workshop?"

When he finally stopped in front of a box of coke, Li Yuanjia's eyes narrowed slightly, and he was really a little embarrassed in his heart.

It's no problem for Han Wangfu to build a papermaking workshop, and movable type printing is a small matter as long as it is not used indiscriminately, and no one cares about glass or something, but if Han Wangfu wants to use a lot of grain to brew high-grade wine, this matter will be a little troublesome.

In this era, food is an important strategic commodity.

Therefore, Li Yuanjia, who has a sensitive identity, would rather go to the palace to say hello to Li Shimin in advance, rather than leave any handle for others.

If this is the case with food, steel should be even more careful.

He is a prince of the Tang Dynasty, he has to get involved in ironmaking, and he will build a big workshop in the future, if he doesn't tell the second child in advance, it will be a bit of a death.

Fortunately, the use of coke is certainly not only for ironmaking.

As Li Yuanjia could think of alone, there was Wang Pu's papermaking workshop, the long process of boiling those barks every time. Especially now that they are trying to make paper from bamboo, I am afraid that it will take longer to boil, if coke is used as fuel, can the temperature be higher can save a lot of time?

There is also a fire in the glass workshop, is it possible that coke will bring some surprises?

After muttering for a long time in front of a box of coke, Li Yuanjia's eyes narrowed again, and he made up his mind: "Well, don't mix the iron-making matter for the time being, and strive to increase the output of coke first, and then talk about reducing the cost......

……

Because of the sudden surprise on his brother's side, Li Yuanjia's mood was extremely comfortable all day, and it even lasted until the next day.

At noon, Li Yuanjia asked Yu Niang to cook a table of good dishes, and asked Mo Hua to get a jar of freshly brewed liquor, planning to drink a good glass. Under normal circumstances, few people will drink at noon, after all, no one knows what will happen in the afternoon, but for King Han, who does not have to go to the court or take care of things, he can really drink whenever he wants, and there is no need to delay any serious business at all.

Of course, he couldn't bear the spirits of more than forty degrees, and he didn't like it, so the low-alcohol distilled liquor that Mo Hua asked him to pick up was probably ten or twenty degrees.

"Ziyo!"

"It's just a pity that this summer is still comfortable with beer!"

After taking a sip at the table, Li Yuanjia shook his head with some regret, and then looked at the brother-in-law who came over before lunch: "What did you just say?" Someone wants to buy alcohol from me? ”

"Yes, and the stronger the better!"

Busy chewing the braised pork ribs that had just been sent into his mouth, Fang Jun said vaguely.

If he was more or less resistant when he first ate braised pork ribs and braised pork, then as he came to Han Wangfu more and more times, Fang Jun had completely liked this practice. Considering the health impact, even Li Yuanjia himself doesn't eat it very often, but every time he comes over, Fang Jun will deliberately order a dish to enjoy it.

In the Liang Guogong Mansion, he would never be able to eat this thing.

"What? The stronger, the better? ”

After listening to his brother-in-law's words, Li Yuanjia's brows furrowed, and he asked, "Who wants to buy it?" There's not a lot of liquor in the house right now, and I've got a lot to use in the future. ”

Originally, I just planned to try it in the northern prairie now, but now, the Tibetan side is also on the agenda.

Even though Li Yuanjia has ordered craftsmen to step up the construction of distillation equipment, and buy all kinds of liquor on the market, and even started to build a brewery outside the city, it is not something that can be done in a short time if he wants to increase production. Therefore, the spirits that have been brewed should be spared.

So for his brother-in-law to open his mouth and want ten jars of spirits, Li Yuanjia is not very willing.

But he also knows Fang Jun quite well, don't look at how unbearable he is written in the history books, in fact, after real contact, Li Yuanjia doesn't think that this kid is really well-developed and simple-minded. When he was the son of Chao Zaifu and Fang Xuanling, and was also called by the emperor as a concubine, how could Fang Jun be a fool?

Let Fang Jun personally come to the door to ask for ten jars of spirits, Li Yuanjia doesn't think that anyone has this face.

Sure enough, after hesitating for a while, Fang Jun swallowed the pork ribs in his mouth, and said with a smile: "Brother-in-law, it's a good brother of mine, and I've been looking for spirits recently......"

"Ziyo!"

After another sip, Li Yuanjia didn't say anything.

Seeing that he didn't understand the expression on his face, Fang Fengzhu glared at his younger brother, and said angrily: "Who wants it?" Speak up! ”

"Well, it's Qin Huaidao of the Yiguo Prince!"

In desperation, Fang Jun had no choice but to say with a smiling face: "He told me several times that he wants to drink spirits, isn't it difficult for me to refuse......
