"The military song is loud and the pace is neat, and the Tang army has iron discipline. Rainbow Literature Network, with you all the way! It is a duty to obey orders, and military regulations and military minutes should be kept in mind. Orders must be carried out, bans must be stopped, and consciously condensed into a fighting collective. Ah, discipline discipline, discipline has you, discipline has me, discipline has infinite combat effectiveness. All actions are commanded, and victory is achieved in unison. Hey, one! Two! Three! Four! ”

In the midst of the singing, the four squares kicked neatly and passed in front of Li Shimin and the ministers in turn.

Seeing the rows of members of the arsenal advancing like a wall, and listening to the high-spirited singing, Li Shimin couldn't help nodding. Those ministers who accompanied Li Shimin also secretly praised.

"Forward—look!" The last team passed through the stands, and the team leader gave the order to correct the step to a unison. Just when the last step of the team was just landing, the song was just finished. This is a bit of a coincidence, not so accurately calculated by Zhao Yunze.

But in the eyes of Li Shimin and others, they thought that the song was sung specifically with the separating movements. The length of the lyrics is exactly the time it takes for the four teams to finish kicking.

"This song was written by Peng Yu?" Li Shimin asked.

"It was the minister who did it overnight last night, and then taught the singing to the hundred people in Yu Chi Baolin's department." Zhao Yunzetian shamelessly took the crystallization of the collective wisdom of later generations to himself.

"** can make a song between them, Peng Yu is really talented!" Fang Xuanling praised, "The lyrics of this song are straightforward and easy to understand, and although the tune is remote, it is extremely smooth. What's even more rare is that this song is very inspiring to listen to. I was happy to see the hunt and wanted to ask Peng Yu for the score of this song, but I don't know if Peng Yu can meet this wish? ”

As soon as he heard Fang Xuanling's words, Zhao Yunze once again had the urge to slap his mouth...... So that you don't have a long lesson! So that you don't have a long lesson! Is 13 so easy to pretend?

"Well...... Lord Fang, in a hurry last night, Zhao just hummed a tune casually, and did not write a score. When I have time, I will write down the score and give it to Ling Lang Zhizhi and ask him to bring it to Lord Fang. ”

"It's good! That's good! Fang Xuanling nodded.

At this time, the four squares had returned to their original positions, and they all stood solemnly.

"Your Majesty, do you want to say a few words to everyone?" Zhao Yunze asked Li Shimin for instructions.

"I've already said what I need to say, so I won't delay them too much. Your arsenal has been preparing for the opening ceremony in the past few days, and everyone must have worked very hard. Let them disperse. ”

"Yes!"

Zhao Yunze got off the stands, walked to the center of the playground, and gave the order to the queue: "Take a break, stand up-"

"Congratulations to Your Majesty and Your Excellency!" The people in the queue shouted together as they had rehearsed before.

Li Shimin and those ministers were guided by Yan Liben to get out of the stands and go to the main hall of the arsenal to drink tea.

After praising everyone who participated in the parade, Zhao Yunze disbanded the team. Yu Chi Baolin's subordinates also returned to the camp. Zhao Yunze and Wei Chi Baolin went to the main hall together to listen to Li Shimin's instructions.

"Peng Yu, I have just discussed with Rank Aiqing, your set of queue training methods is very worthy of promotion." Li Shimin said to Zhao Yunze, "Today's people have only been training for less than a month, and their queue cooperation can achieve such results, which is very rare!" ”

The eldest grandson Wuji also said at this time: "Moreover, the movements of those people are rhythmic, crisp and neat, and they are very spiritual. This is the style of my Datang soldiers. ”

Several other people also echoed the words of Li Shimin and the eldest grandson Wuji.

Li Shimin said again: "The martial arts hall of the Xiande Hall is now holding classes every day. After Peng Yu straightened out the affairs of the arsenal department, he also set aside an hour every day to teach the new queue action of the generals in the martial arts hall. I want to use three months to popularize this set of actions to the garrison army in Chang'an. ”

"Obey the order!" Zhao Yunze replied.

After Li Shimin told Zhao Yunze, Yan Liben and other officials of the Arsenal Administration some things, he left the Arsenal Administration with the group of bigwigs.

******

After the opening of the Arsenal Administration, everything has also entered into normalcy.

Yan Liben had already learned how to make thunderbolts and bamboo rockets. Within a few days of the opening, Yan Liben was training the craftsmen. Other officials are also busy with their own affairs.

On this day, Yan Liben was silently invited by Cheng Chu into Zhao Yunze's council room.

"Chu Mo, when you are resting one day, you go home and tell Grandpa Cheng, and let him drive out the batch of furniture customized by our arsenal first." Zhao Yunze sat cross-legged behind the bookcase, and said to Cheng Chumo very unhappily.

"Okay, I'll take the time to get my dad down." Cheng Chu replied silently.

Zhao Yunze was holding a quill at this time, writing something on a piece of paper. Now, the officials of the Arsenal Special Administration have also learned from Zhao Yunze to draft documents with a quill pen. This thing is fast at writing.

It is said that the number of geese in the village closest to the Arsenal has decreased significantly because of the quill incident. They all let Du Gou's purchasing manager buy them off. The subordinates of the Arsenal Special Administration also ate a few meals of goose meat and tooth sacrifices.

Soon, Zhao Yunze put his pen to paper. He handed the piece of paper to Yan Liben and said, "Brother Yan, I have thought about it, before we officially start manufacturing firearms, we will first purify the sulfur and saltpeter. In this way, the power of firearms will certainly be greatly increased. ”

Yan Liben looked at what was written on the piece of paper and asked, "Brother Zhao, what is written on it is the purification method of sulfur and saltpeter, right?" ”

"It's the way to purify." Zhao Yunze nodded.

Yan Liben whispered to the piece of paper: "Sulfur purification, heating and melting raw sulfur to filter out the unmelted substance. Continue to heat and stir constantly to vaporize and evaporate some of the impurities. Until the sulfur boils, the sulfur gas is collected, and then the sulfur gas is cooled and solidified to obtain purer sulfur.

"Saltpeter is purified, seven liters of water are added to the cauldron, and 100 catties of nitrate are added. Burn three decoctions, and then put a pound of grass and wood ash water. You can also measure the size of the pot, or put 50 catties of nitrate, and stop using half a catty of ash water. The impurities in the nitrate also have a little gray water for plants and trees, which are naturally separated, and the impurities do not sit with the water. Burn it again and fry it, out of the porcelain urn, the mud foam sinks to the bottom, and the nitrate is in the middle. Put it for one or two days, clear the impurity water, scrape off the bottom mud, and dry it every day to get nitrate. ”

After reading it, Yan Liben smiled and asked Zhao Yunze: "Brother Zhao, why is the description of the method of sulfur and saltpeter purification completely different in style?" ”

"Well, I thought about the method of refining the sulfur myself, so I used the vernacular; The method of purifying saltpeter is taken from ancient books. Zhao Yunze explained.

"Is there a record of saltpeter purification in ancient books, what ancient book is it?"

"Wu Beizhi!"

"Wu Beizhi? The title of this book is very obscure. Yan Liben said.

Of course, it is secluded, "Wu Bei Zhi" was written by Mao Yuanyi in the Ming Dynasty, this year, the ancestors of Mao Yuanyi's ancestors still don't know if they were born.

"Don't worry about "Wu Bei Zhi", Brother Yan will see if this method is feasible." Zhao Yunze snorted.

Yan Liben pondered for a while and said, "The purification of saltpeter is relatively simple and easy. But how to collect sulfur gas for cooling and solidification in the purification of sulfur? ”

"I've already thought about it, and I'll be able to create an instrument that can be used to collect sulfur gas."

After Zhao Yunze finished speaking, he said in a mysterious low voice: "That kind of utensil can not only be used to purify sulfur, but also to steam wine." ”

"Steamed wine?" Yan Liben was at a loss.

"Brother Yan will find out in a few days."

Yan Liben saw that Zhao Yunze had sold Guanzi, and he didn't ask any more. He read the paper again.

Suddenly, Yan Liben's eyes lit up, and he said, "Brother Zhao, since the method of purifying sulfur can be used for other purposes, does this method of purifying saltpeter also have other uses?" ”

"It should ...... Yes, right? Zhao Yunze said uncertainly.

"Brother Zhao, shall we try it and see if this method of purifying saltpeter can be used to purify table salt." Yan Liben said excitedly.
