The middle-aged man with long hair couldn't help but be shocked when he heard Old Man Han's words: "Uncle Han! How so? The eldest brother guarded Luzhou to resist Nan Chen, how can he come back to Luzhou at this time and lack the main general?

Uncle Han, it is not easy to mobilize the Luodu garrison, but it is even more difficult than lifting the curfew temporarily. Now that the empire has just been established, no less than the Zhou period, the slightest change in the army must be reported to the imperial court, not to mention the garrison outside the city of Luodu.

Moreover, the drums and flowers are about to be picked, and the talented people from all over the country who come to participate in the grand event, and the Confucians who rushed to Luodu to assess the need for garrisons to ensure safety at that time.

Uncle Han, you still tell your nephew the truth, is there anything serious? To mobilize the Lodu garrison? Could it be that the Lodu magnates have secretly changed? ”

Old man Han waved his hand and said, "It's not what you think. However, this matter is also very involved, and the old man from His Majesty will personally explain it.

Lu Zhi, this matter involves the secret method of the Immortal Palace, old man, I can only count on this kid, if this success is achieved, the recent drought in Dasui can go to seven or eight out of ten, and the military rations after the autumn will no longer be worry-free. Such a big event, how can the old man not be vigilant, you must remember not to leak it. ”

The middle-aged man was shocked after hearing this: "What! Is there such a thing?! So, is the rumored Xiao Gongzi sleepwalking in Asgard true? How is this possible! This doesn't make sense!

It's also incredible, although the nephew has some doubts, but since Uncle Han personally came forward, the nephew will definitely try his best to do it! If it really involves drought, my nephew naturally knows how to do it. ”

Xiao Mo listened to it at this time, and he was speechless in his heart, don't people in these years have any doubts about the superstition of immortals?

Could it be that because Xiao Si was too cowardly and idiotic before, he suddenly became a famous talent in Luodu. So that people believe it unconsciously?

However, Old Man Han had no intention of staying in the mansion at all, no matter how much the middle-aged man named Lu Zhi retained, Old Man Han turned around and left after explaining the matter.

It seems that it is very uncomfortable for Old Man Han to stay in the mansion for a while longer.

When the middle-aged man saw that Old Man Han was leaving, he couldn't help but speak: "Uncle Han, it's been more than ten years, you have been in seclusion, except for the eldest brother, if something big happens, you will go to help." Nephew, you haven't seen this and the Han family, but you haven't seen it in all these years.

Finally, you are willing to come to see your nephew, why don't you leave after dinner, and your nephew will accompany you for a drink. ”

Old man Han said with a smile: "Don't say it, now let the old man and I go to other places to eat, the old man is really not happy."

Since eating this kid's Asgard food, eating the previous ones is really like chewing wax.

Haha, this kid is about to open a restaurant, and when the time comes, the old man will naturally have a drink with you. ”

As he spoke, he took Xiao Mo and walked outside the mansion.

Wait until Xiao Mo gets into the ox cart first.

The middle-aged man whispered to Old Man Han: "Uncle Han, why are you so unusual to this kid, and you still live with this kid." I haven't seen you come to see your nephew for more than ten years. ”

Old man Han smiled and said, "There is naturally an old man's truth in this, you can go back, you don't need to send it." You just need to make arrangements in advance for curfews and the transfer of garrisons. Don't worry about the rest. ”

The middle-aged man listened respectfully and said, "Yes, Uncle Han." ”

After getting into the ox cart, Xiao Mo's unhappy expression was very obvious.

Old man Han looked at it and smiled: "You stinky boy, why do you still put on a stinky face after the matter has been done for you?" Looking for a beating? ”

Xiao Mo rolled his eyes and said, "I said that you are an old man, you are a person who has been such a big official, why do you like to deceive people?" Can there be some basic trust between people? ”

Old man Han haha: "You kid knows, don't you call me old man the same?" What's the difference between telling you or not? It's just that you stinky boy is getting so fast! I just called the old man, my old man Han, and this time the ox cart changed? ”

Xiao Mo was a little speechless and said: "That's because I gave you face to this old man in front of so many people, don't think that if you change your identity all of a sudden and become a big man with a head and a face, you can let the young master and I lower my posture and serve you." No way! ”

Han Lao smiled and said, "Hahaha, good!" Very good! That's it, old man, I like it. ”

Xiao Mo said disdainfully: "If you like to have a fart, for you old man, curfew is not a matter at all, and you actually deliberately dig me so big two pits to jump." It's so bad! ”

Old man Han smiled when he heard this, but Xiao Mo always felt that the old man's smile was a little treacherous.

Erniu's technique of driving an ox cart is also getting older, and the kid actually remembered the way back.

This kid has obviously grown a lot of meat and strengthened a lot in the past few days, so it's really right to be able to eat, and his body bones obviously don't look like a child.

When he arrived at the door of the restaurant, Zi Ling ran over prettyly, and of course, faster than Zi Ling, there was a white shadow that rushed into Xiao Mo's arms.

If it is according to the rules, no matter where Xiao Mo goes, Ziling Ziyi should be close to him, after all, they are Xiao Mo's personal girls, this is their duty. But Xiao Mo has a headache when he goes out, and he always feels that it is very unnatural to be followed by two maidservants, so now Xiao Mo has always been accompanied by Erniu when he goes out.

As soon as Zi Ling saw Xiao Mo, he said: "Young Master, someone just sent three carts of things, saying that Miss Wang asked them to send them, and now those things are put in the backyard, young master, do you want to go and see them now?" ”

Xiao Mo smiled when he heard this: "Oh? So fast? Sister Ziyao's efficiency is really okay. ”

Old man Han was puzzled and said, "Zi Yao told the old man that what you want from this kid is said to be very important. But what the hell are you kid going to do with it? Those things aren't cheap, so why do you want so much? ”

Xiao Mo replied mysteriously: "Of course it's useful, Qi Yu and Kai Kai are counting on this thing, but three cars are still too few, if it is used for Qi Yu, the amount needed is far more than three cars."

You old man will come over to help later, I really can't believe others, this thing to get out is too dangerous, once the formula leaks out, it's not a good thing. Besides, your old man is good and can withstand the bombing. ”

Saying that, Xiao Mo walked towards the backyard, and Old Man Han also touched his beard and followed thoughtfully, but he didn't understand what it meant to be able to withstand the explosion.

I have to say that Wang Ziyao's ability in business is indeed outstanding, Xiao Mo looked at the three cars of things sent, and the quality was very top-notch, of course, this was measured by the level of craftsmanship at this time.

If you compare it with the purification process of later generations, then these materials must be a little rough.

However, what Xiao Mo originally wanted to do was only the most basic black powder, which was simple and practical, and not very powerful, but it was enough to make fireworks.

But what made Xiao Mo more helpless was that what Xiao Mo and Wang Ziyao said at that time was one sulfur, two nitrate and three charcoal, so Wang Ziyao bought it according to what Xiao Mo said, the amount of willow charcoal was obviously the largest, and the saltpeter was the least.

Xiao Mo only remembered now that he had forgotten the most important point of the gunpowder ratio, which was that this sulfur dinitrate and three charcoal was not actually the mass ratio required to prepare gunpowder, but the structural ratio in the chemical equation.

The mass ratio of the components of real black powder is 75 percent saltpeter, 15 percent charcoal, and 10 percent sulfur.

Therefore, the quality ratio of the three materials purchased by Wang Ziyao is exactly the opposite, which makes Xiao Mo a little helpless.

However, because of the large amount of materials purchased, it was enough for experiments.

The gunpowder experiment is not something that can be experimented with by saying that it is an experiment. Experimental safety is the most important thing, Xiao Mo doesn't want to be missing arms and legs before it is done.

This knows that the ratio of gunpowder may not necessarily be able to make black powder, not to mention that this thing is an extremely dangerous existence.

If Xiao Mo doesn't get it right, there is a high chance of an explosion, and blowing up some building rockeries or something is not a big deal.

It would be troublesome if the explosion injured someone in the family, and in this era of extremely poor medical conditions, injuries and wound infections were almost equivalent to death.

Therefore, after Xiao Mo read the materials again, on the one hand, he asked Erniu to go to the Wang family to send a message to explain the amount of materials he really needed. On the other hand, it was to have people move all three truckloads of materials to an abandoned yard.

And Xiao Mo asked the entire yard to be sorted out and emptied, and the center of the yard became a place for testing gunpowder. Because Xiao Mo is only preparing black powder, he only needs to spread out the black powder and ignite it during the experiment, and the gunpowder will cause some smoke at most when it is spread, and the possibility of explosion is not large, and the risk factor is relatively low.

Then Xiao Mo asked the puzzled old man Han to prepare a pair of bows and arrows.

After Xiao Mo knew that this old man was Han Xiong, he naturally knew that this old man's martial arts were first-class and his arm strength was amazing. Archery is also really good. In this way, Xiao Mo thought of a way.

At that time, the task of igniting the black powder will be handed over to Old Man Han, in order to ensure safety, when the time comes, make the front end of the bow and arrow into a small torch, and shoot it directly from a distance, and it will be over, even if the character is extremely poor and it really explodes, Xiao Mo will hide far away.

Although Old Man Han was confused, he knew that this was the secret technique of the Immortal Palace, which he could not understand, so he was naturally very cooperative.

Then Xiao Mo issued a ban, except for himself and Old Man Han, no one in the family was allowed to enter this small courtyard, not even Xiaoya.

Next, Xiao Mo went headlong into this humble laboratory and started the production of gunpowder.

Old man Han was very measured, since Xiao Mo didn't say to let him in to help, it must involve secret arts. In this era, family heirlooms and secret techniques are precious and precious things, and even the lifeblood of a family, so except for a few people who are not right, people are very conscious not to spy on these.

So Old Man Han sat on the threshold of the small courtyard and acted as a gatekeeper.
