"This ...... How is it possible?" The old man muttered, feeling that his entire outlook on life had collapsed, and his old face was as if he had been slapped dozens of big mouths by Lin Zifan in public, and it hurt badly.

"Your Majesty!" Lin Zifan bowed his hand slightly to the empress: "This method is called saltpeter ice, as long as there is enough saltpeter, you can make ice cubes like the minister!"

"If you don't eat it, you can just put the saltpeter in the water and stir it evenly, if you need to eat it, you need to make ice like the minister, and the ice in the small basin can be eaten!"

"Is it really that simple?" General Huo's breathing became more and more rapid, and he felt a little incredulous.

Saltpeter ice-making, this method, for the Tang Dynasty, or for the Tang Dynasty soldiers, is really of great significance! In the past, the casualty rate of the Tang Dynasty soldiers would increase exponentially in summer, just because the weather was hot and they could not beat the heat!

If saltpeter ice is really that simple, is it still a problem in hot weather?

"It's so simple!" Lin Zifan confirmed again.

When General Huo heard this, he was elated, and then laughed three times: "Okay, good, Lin Logistics Officer, there is you! General Ben owes you a great favor! With this method of making ice, even in the hot summer, what are my Tang Dynasty soldiers afraid of?"

Lin Zifan touched his nose, a little embarrassed, this General Huo speaks in a set way, and he has a loli body, but he speaks in the tone of this bad old man, the contrast is really great?

"Saltpeter ice ...... Saltpeter, is it enough?" the empress was not too excited, she was much calmer. The method of making ice is simple, but the premise is that the materials must be sufficient!

"Your Majesty!" Lin Zifan smiled: "This is also what Chen Zheng wants to say." ”

"There are many ways to obtain saltpeter, for example, Li Shangshu knows one, but the amount of saltpeter obtained by this method will not be too much, for example, for Chang'an, it is the limit. ”

"Can it only be used for Chang'an?" General Huo's face changed slightly, and Fang Cai's excitement gradually cooled.

"General Huo, don't worry, the lower official hasn't finished speaking. Lin Zifan smiled faintly: "Fang Caichen has already said that there are many ways to obtain saltpeter, and Li Shangshu knows that is only one of them, and it is a relatively inefficient one." ”

Actually, Lin Zifan went to find saltpeter by himself, and then sold it for money or something, but this is all a small way. Now that he has felt that he has 'won't win' the empress, he will then use Datang as a springboard to dominate the whole world. At this stage, it is natural to build Datang into a more powerful place!

What's more, the method of obtaining saltpeter, even if it is hidden, cannot be hidden, people can understand it as long as they see it, and there is no secret at all.

So, instead of hiding it, it's better to take it out generously, and you can still make a great achievement, why not?

"And the minister, it is recommended to use the second method, which is the saltpeter ......"

"I am Datang, the land is vast, although the soil is relatively poor, but I think about it, it is not difficult to find saltpeter mines! When the time comes, as long as it is mined, it will continue to provide saltpeter with energy, even if it is supplied to my entire Datang for use, there is no problem, not to mention that it is only promoted to the use of the whole army?"

"Saltpeter mine?" the empress's eyes lit up: "There is still such a vein?"

When the civil and military officials heard this, they also discussed a lot, and they all felt very novel. At the same time, Li Shangshu was also surrounded by three layers inside and three layers outside.

Compared with the saltpeter mine, the method of obtaining saltpeter mastered by Li Shangshu is currently the best, in this hot summer, who doesn't want to put more ice cubes in their home to cool off?

As a result, Li Shangshu instantly became a sweet spot in the eyes of many ministers.

She glanced at Lin Zifan with appreciation, and was very satisfied with her behavior of 'worshipping his younger brother'.

In fact, Lin Zifan is a person with clear grievances, if you are kind to me, I should repay you with a spring, and if you have a grudge against me, hehe......

Li Shangshu and Lin Zifan can't talk about any kindness, but in the eyes of the two, they can be regarded as 'fox friends and dog friends' who 'smell like', and the two sides are mutually beneficial, and there is nothing bad about it.

Li Shangshu helped Lin Zifan find saltpeter, Lin Zifan mentioned Li Shangshu by the way, where are the two of them, why not?

"Yes, Your Majesty. And saltpeter mines are not difficult to find, as long as you find some saltpeter in the wild, and then look for and dig nearby, you may find it!" Lin Zifan nodded with a smile.

General Huo jumped out eagerly: "Your Majesty, please allow the last general to leave the court ahead of schedule! The last general will immediately take people to the wild place to find saltpeter veins!"

"Saltpeter ice making is too important for my Tang Dynasty soldiers, and it can't be delayed!"

"Your Majesty!" Zhang Ru jumped out and bowed his hand to General Huo: "General, let's let the last general go!

"There is no need to rush this matter, you two, now I am afraid that you don't even recognize saltpeter, how can you look for it?"

It seems like it's really ...... They don't even recognize saltpeter, looking for a ball?

"This is not difficult, after retreating from the dynasty, I will take some saltpeter samples to the two generals, and when the time comes, just look for the samples. Lin Zifan smiled slightly.

"So be it. ”

The empress nodded, then looked around at everyone, her red lips lightly opened.

"Logistics officer Lin Zifan, invented the method of saltpeter to make ice, solved the problems of my Datang for many years, and saved the lives of countless soldiers of my Datang, which is indispensable!"

"From today onwards, the logistics officer Lin Zifan will be promoted to one level, worship the seven products, and be a civil and military official, can you have any objections?"

"Who dare?" As soon as the empress's voice fell, General Huo jumped out: "Whoever dares to say a word, Ben will retire from the dynasty and go to her house to learn from her......"

As a general, Huo Yuanyuan attaches great importance to the lives of soldiers, and every summer is also the time when she has the most headache and anger, but for many years, she has been at a loss.

Nowadays, Li Zifan's invention of saltpeter ice-making method can solve the problem from the root, which is a great gospel for the Tang Dynasty soldiers!

At this moment, whoever dares to oppose Lin Zifan's promotion, General Huo Da will fight hard with whom......

"Chen thinks......" The national teacher spoke, and General Huo Da glared at him instantly. The national teacher glared back without hesitation.

"The merits of Officer Lin Logistics are not more than a mere seven-rank position is enough to offset the ......"

MMP, General Huo scolded his mother in his heart. Why do you have something to say, hurry up, don't believe it? I've pulled out my forty-meter broadsword, it's hard to collect it, okay?

Made, Zhi ...... Yong Shuangquan is talking about you, right?

Regarding the fact that he almost accidentally injured the 'friendly army', General Huo Da said that he was a little embarrassed.

Well, just temporary allies.

The empress glanced at the national teacher lightly and said, "It's true that it's not enough to offset such a great achievement, but this is not what you said, Lin Zifan is a first-order man, he is an exception for officials, and he can't be promoted too quickly anyway?"

"What's more, since the founding of the Tang Dynasty, there has been no precedent for such a quick promotion?"
