Chapter 55: Preparing to go to Chang'an

"Hahaha......" Xu Qing once again came out of his "laboratory" with a black face, today he has done eighteen experiments, and finally put the fire. The process of making the medicine has been mastered.

As an engineering student in later generations, Xu Qing faced fire. The ingredients of the medicine are familiar, but the weight ratio of the three raw materials of fire nitrate, sulfur and charcoal is 15:2:3 respectively. However, theoretically it can, it doesn't mean that the actual operation is good, and there are not a few experimental classes in a year, let alone doing it. So everything has to be crossed by feeling the stones yourself.

It turned out that Xu Qing only thought about crushing fire, sulfur, and charcoal and mixing them together in proportion, but it turned out to be smoke. Fog. Bullets, light smoke, no fire. Later, Xu Qing remembered that it was necessary to use egg white granules to ensure the combustion to the greatest extent, which was prone to explosion.

Black. Fire. Four grams of medicine can produce a big explosion, Xu Qing did not dare to use it indiscriminately, and there was no weighing instrument to calculate "grams" in the Tang Dynasty, which made Xu Qing very annoyed. Eventually, Xu Qing built a utensil that could hold one liter of water, put it in it, and then weighed the same weight of dry wood on a scale. The blocks were then cut to different sizes in proportion, and a set of weights that could be counted as grams was created improvisely, which was not very accurate, but it was still easy to use.

Mix the three ingredients before granulating, then add the egg whites, stir and shake. Xu Qing is afraid of an accident again, *Who is right about this thing? In case the temper is bad, it's not good to be disfigured or something, but dare to hang twelve hearts and do it slowly.

Wait for the fire. The medicine formed into a little bit of large particles, and Xu Qing weighed out thirty grams and put them into a fist-sized clay pot. Thirty grams must not be enough, Xu Qing put some more cotton, cotton can not only fill the space, but also keep it dry, and press the cotton hard to fill the clay pot. Xu Qing filled the clay pot, took out the lead he made, inserted it into the *, and then took a wooden stopper to close the mouth. The wooden plug is of the kind of two halves, and before plugging the opening, you can put the lead in it first, and then clamp the plug into the mouth.

The lead is very long, Xu Qing has calculated, such a long section is about enough to burn for twenty seconds. That was enough time for him to get behind a thick brick wall, and then he put a brass basin over his head, and a wooden plank behind him, enough to fall in between. Although so many protective measures did not reflect their role more than a dozen times, Xu Qing still did not dare to take it lightly.

After putting the clay pot away, he immediately returned to the back of the wall, ready for what seemed to be in place. Secretly counting 123 in my heart...... As a result, there was no movement. Xu Qing thought to himself, his luck shouldn't be so bad, and he didn't even hear the sound again and again. Xu Qing didn't dare to stick his head out to look, he suffered a loss when he was a child playing artillery battles. Once, there was a cannon battle that didn't go off for a long time, Xu Qing picked it up and checked it, but it rang off as soon as he got it in his hand.

No matter how timid he was, he dared to go out to see it after waiting for ten minutes, but it turned out that there was no fire.

"Damn, this time I checked the bladder capacity." Xu Qing shook his head and lit it again, and after repeating the sprint, he hid behind the wall, took a basin to cover his head, and the wooden board blocked his back. As soon as I finished doing it, I heard an unprecedented explosion:

"Bang !!"

Xu Qing was overjoyed and took away the copper basin, but saw a few bright spots of light on the roof, and then a piece of tiles, shaking and about to fall, Xu Qing hurriedly took the copper basin to block it again.

"Hehe, this power, not bad......" Xu Qing was overjoyed, cleaned the house, and then took the remaining half a catty from just now and planned to go out, and after thinking about it, he took another kind of *. Pushing open the door, Xu Qing, whose hair was unkempt and his face was half black and half white from smoke, laughed, like an old Taoist priest who had broken through the transformation of gods after many years of retreat. Of course, this is what Xu Qing thinks himself, and others don't think so. Xu Qing walked out of this small courtyard, and the people were frightened, shouting that something had happened to the master.

"Hey, hey, next, let's make a pistol......" Xu Qing said to himself, not caring about other people's opinions. However, the pistol thing is very complicated, and it is not good to do it in a few days, but fortunately, Xu Qing used to pay attention to the structural diagram of the flintlock pistol, and he also drew it when he was studying engineering drawing.

"Master, the bath water is boiled......" It was Xu Qingshui's maid Xiaoying who spoke, and now she is Xun Xue'er's personal maid.

"Mmmm, it's a good ......" Xu Qingmei hid the * in her arms, and then went to the bathroom to take a bath.

August and autumn are refreshing, and it's almost August 15, the last time I had August 15, it seemed that I had made an official, and I had a big drink at the inn with those government soldiers.

Autumn, as long as the poet will be sad. The peasants are all happy, because the wheat and rice in the field are almost ripe, they are harvested quickly, they are sun-dried, they eat new rice and new noodles, a big bowl of soup cakes, steamed cakes are soft and harmonious, the rice is piled up sharply, and then take out the pickled vegetables in spring and summer, and drink them beautifully and eat them as a family. There's nothing happier than having a full stomach!

If you say that the happiest peasants are still the peasants of Xuzhuang, followed by the peasants of Hongshan Township, the rent is low, and you can let go of your own family to eat for a few more days.

Xu Qing's smaller five-hundred-stone granary had already been built, just waiting for the grain to enter the warehouse. Because it can be folded in half, plus the loss, it can collect up to 8,000 stones, and it is barely enough to squeeze it and add the warehouse in Xufu. The rest of the folded colors are cotton cloth, fur, copper coins and so on.

Xu Qing didn't interfere in the grain collection this time, just to see if his hands-off shopkeeper system was perfect and effective. After all, I'm going to Chang'an, and I don't know when I'll go home.

Xu Qing thought to himself: This time I went to Chang'an, Li Yuan was only afraid that he would give me a real official, otherwise he wouldn't let me go to Chang'an to see him, maybe he would be sent to the north to fight the Turks, alas......

Li Er and Li You both had the intention of wooing me last time, and I don't know what they will do to me when they get to Chang'an. Xu Qingdu has resigned from the government and lived in seclusion, turning a blind eye, and after a few years of the changes in Xuanwumen, he will create something else and become a petty official again.

As a traverser, Xu Qing is not optimistic about the prince's party in his bones, but he does not want to stand on Li Shimin's side, and from the historical data, the people on Li Shimin's side are better to get along with. However, history is only history after all, he can reflect the truth, but those truths are hidden under layers of lies, and Xu Qing still doesn't know what choice is best for him. But in general, this time it is better to start later, because I don't know if he will have an impact on history after he comes to the Tang Dynasty, and whether it will change the outcome of the Xuanwumen Incident.

"Whew~" Xu Qing, who was in the bath, took a deep breath and buried his head in the water.
