Charlie Cao was almost scared to pee, he didn't have seen the explosion scene, the reason why he was scared like this this time was that he was completely unprepared, plus his alchemy is made of saltpeter and sulfur, these two things are to be eaten in the stomach, think about what the scene will be if the pill explodes in the stomach? I guess it's going to end up in pieces, right?

When he stood up, his face was already pale, his legs were still trembling, and he might kneel down at any time, at this time Qin Dong was already squatting in the sheepfold to observe the situation at the scene of the explosion, he gritted his teeth and walked over.

After seeing the situation in the sheepfold, Charlie Cao twisted his head to the side on the spot and vomited, there were originally six sheep in the sheepfold, all of them were alive, and now four of them have been blown into a sieve, and they are covered with blood and died on the ground, and the other two have been blown into pieces, and the mutton that is broken into pieces is scattered everywhere, and the intestines and other sheep are scattered in the sheepfold bloody, and there is a pit in the middle of the explosion, the pit is not deep, and it is not big, it seems that the downward force of the explosion is not large.

Qin Dong took out a piece of dried cheese from his pocket and put it in his mouth to chew, and said vaguely while chewing: "The power of such a big jar is a little smaller, just listening to the sound, in fact, it doesn't have much destructive power, and I don't know how powerful the directional blasting is."

The reason why saltpeter, sulfur and charcoal explode when ignited is because of a chemical reaction, which is known to all junior high school students in later generations, and the proportion of their chemical reaction is 1 sulfur, 2 saltpeter, and 3 charcoal, respectively, compared with other explosives. The explosive power of black powder was not very large, and the purity of these saltpeters and sulfur brought by Charlie Cao was not high, and they contained a lot of impurities. This made the explosion much less powerful than expected.

Hearing this, Charlie Cao turned around, raised his arm, wiped the stains on the corners of his mouth with his sleeve, and said, "This power is still small? ”

"Why isn't it small?" Qin Dong said: "If you can blow up the city gate or the city wall, how energetic do you say?" With a bang, the walls fell, and my army rushed directly into the city, no matter how many people defended it, as long as the city was broken. The military spirit will be lost, and the city will not be able to hold it! In the future, with this thing, wouldn't it be as easy as digging for things? ”

Charlie Cao was stupid when he heard Qin Dong's words, and he couldn't help but think. That's right, it wasn't once or twice when there was an explosion during alchemy in the past, so why didn't you think of using this method to attack the city? If such an explosion could blow down the walls and break through the gates. What else do the walls do? In front of this thing. Isn't the whole city as good as a girl wearing only a scarf? With a slight pull, the girl was naked.

Charlie Cao looked at Qin Dong differently, his eyes were full of awe, not because he was afraid, nor because Qin Dong was an official, but because he saw Qin Dong's future, with this explosive formula of explosives, Qin Dong's army was absolutely invincible. At least there is no city that he can't break, so it goes. Qin Dong's future is definitely rich to the extreme, at this moment, Charlie Cao decided to kill and hold Qin Dong's thigh and never let go, it is absolutely impossible to be a minister from the dragon, he immediately bowed down and saluted: "The lord is wise, with such a sharp weapon, the lord's divine power will inevitably shock the entire Obarro, and the poor Dao is willing to follow the left and right, let it be driven!" ”

Qin Dong was stunned when he saw Charlie Cao's appearance, and then laughed: "Old Cao, old Cao, which one are you singing?" Hurry up, hurry up! ”

"If the adults don't agree, the poor road won't get up!" Charlie Cao, an old man, has also begun to play a scoundrel, in order to be a minister of the dragon, this old boy has given up his face.

Qin Dong didn't expect that the power of this black powder was not great, only a few sheep were killed, but he blew up Charlie Cao so much that he was willing to be his little brother, seeing Charlie Cao doing this big gift, Qin Dong had to agree: "Okay, okay, you get up first, let a monk give me such a big gift, I don't want to be remembered by your Sanqing Immeasurable Dao Venerable!" ”

"Thank you, sir!" Charlie Cao breathed a sigh of relief and got up.

Qin Dong looked at the scene in the sheepfold again, turned around and asked Charlie Cao, "Do we have saltpeter and sulfur in our market to buy?" ”

Charlie Cao arched his hand and said: "My lord, this kind of thing is generally used as medicine, if you want to buy it, you can only buy it in pharmacies, if you want to buy it in large quantities, you must directly order it from a medicinal herb merchant!" There are some pharmacies in every city under the jurisdiction of the adults, but the inventory of these pharmacies is certainly not too much, and there are no medicinal herb merchants in the Xiongnu Empire who specialize in selling this kind of thing, only the Eastern and Western Roman Empires have medicinal herb merchants to sell, if you look for them in the jurisdiction of the adults, you can buy saltpeter and sulfur from each pharmacy, and you should be able to raise a batch, but the amount will not be very large."

Qin Dong immediately said: "First buy all the saltpeter and sulfur in the jurisdiction of this lord, and then take Razlog first, this matter will be handed over to you, if you need money, go to Wang Liu, just say what I said, in the future, the matter of finding a Roman Empire medicinal material merchant to order a large batch of saltpeter and sulfur will also be handed over to you to be responsible, how much you want, but you must not disclose the use and specific detailed formula of these things, you must keep it absolutely confidential, if the use and formula of these things leak out, I only ask!" ”

Charlie Cao hurriedly bowed and said, "Yes, my lord, the poor road must be strictly guarded against!" ”

After receiving Qin Dong's instructions, Charlie Cao took a few people assigned by Qin Dong to buy saltpeter, sulfur and charcoal on the market, and after a day of purchasing, the saltpeter and sulfur in the major pharmacies in Qin Dong's territory were almost wiped clean, but they only made up a total of one hundred and twenty pounds.

Qin Dong believed that the content of impurities in these sulfur and saltpeter was too high, which made the ratio of several raw materials of black powder inaccurate, thus affecting the power of the explosion, so he asked Charlie Cao to purify the saltpeter and sulfur respectively, add charcoal to mix, and stir evenly to make the three substances mix evenly, and a total of 142 pounds of black powder was obtained.

Two pounds of black powder from the refined zuò were taken out and the test was carried out again, and sure enough, the explosive power of the black powder prepared after the raw materials were purified was indeed much stronger, and Charlie Cao recorded the purification process of the three raw materials and the formula of the black powder in detail and kept them properly. Then he sent a return to Qin Dong.

At a certain rate, the power of an explosive explosion depends not only on its physical properties, but also on the amount of explosives. The more explosives, the greater the power of the explosion, to blow down the city gate or city wall, of course, the black powder needed must not be too little, the destructive power of the explosion must be very large, so it is necessary to carry out blasting training for the person who carried out the blasting, under the instructions of Qin Dong. Charlie Cao took Qin Dong's warrant and selected a hundred people from the army to form a demolition team, making one centurion and three demolition teams. Each group of ten people, and the other seventy people, divided into seven ten-man teams, were specially responsible for protecting the safety of the members of the demolition team during the siege, and did their best to make the blasting work as smooth as possible.

Under pressure and motivation. Charlie Cao figured out a series of processes for carrying out blasting. Charlie Cao first trained the blasting process of the three blasting teams of the demolition team, he split the blasting process into several parts, let the blasting team train one by one, and then combined these parts to form a complete set of processes, and finally cooperated with the seven ten-person teams responsible for protection to complete the entire blasting process.

Just when Charlie Cao was training the demolition team, Qin Dong had already commanded the First Route Army to set off, and the vanguard was led by Tuo Long with 300 archers and 200 light cavalry to open the way. Qin Dongzi led 300 light cavalry and archers of the guards, and 400 heavy infantry at the Duoyin rate. In addition, Faisal and Rus's 1,000 light infantry, Wang Liu's baggage army of 400 people followed, and the Second Route Army under the command of Muren had also begun to secretly assemble in the northwest Pana, and as soon as Qin Dong's order was issued, he immediately drove to the southwest towards Lila Mountain, and went down the Lila Mountain to the southwest.

……

Razlog, this is a fortress located in the middle of the Lila Mountain, the Eastern Roman Empire spent several years to build such a fortress in order to resist the southern invasion of the Germans, the fortress of Lazlog is not a separate and existing zài, there is a village on the right side of the Lila Mountain, called the Silver Pine Village, the location of the Silver Pine Village is flatter than the other sections of the Lila Mountain, so when the Eastern Roman Empire built the Razlog Mountains, the Silver Pine Village was built on the right side of the Silver Pine Ridge, In order to prevent the Germans from passing through Guò here and crossing the Rila Mountains to the south, but now the Silver Pine Village and Lazlog are in the hands of Odoases, and the Eastern Romans have also retreated to the area south of the Rhodope Mountain, and the large land south of the Lashan Mountain here is given to these three Germanic tribes to live, and the two sides have already reached an agreement not to invade each other, and the Eastern Romans also need these Germanic peoples to resist the invasion of the Huns.

There are only two gates in Razlog, namely the south gate and the north gate, the east and west sides are built on the mountain, the cliffs on both sides are steep, up to dozens of meters, and it is difficult to go up the mountain, and the only way to pass from here is to break through Razlog or Silver Pine Ridge.

Some Germanic peasants outside the north gate are ploughing the fields, after so many years, these barbarians also followed the Eastern Romans who stayed behind to learn to farm, began to live a life of farming, and some people graze cattle not far outside the city, the number of herds is not much, only a few dozen cattle and sheep, they dare not go too far to the north, the north is the territory of the Huns, and there are often Hun cavalry patrols.

In November, when the weather cooled down, a layer of hoarfrost froze on the meadows at night, and the sun rose to melt the frost on the meadows, and by noon the temperature had risen a little and warmed up, and the Germanic people who had been working in the fields and grazing were ready to return to the city for lunch.

At this time, the earth shook slightly, and soon many Germanic farmers and herdsmen felt it, and a herdsman lay on the ground and put his ear to the earth, and after listening carefully for a while, his face changed greatly, and then he jumped up and shouted: "Run, there is a large force of cavalry from the north, run, go back to the city!" ”

The others heard the herdsman's shout, and the others ran to the city gate with their hoes, and the people who were just about to turn around saw some black spots on the northern horizon, and shouted in a panic: "Run, the Huns are coming, the Huns are coming!" ”

In the chaos, hundreds of Germanic peasants and some herdsmen who were working outside the city ran frantically to the city gate, and those herdsmen did not even want their livestock, and ran into the north gate on their horses.

Tolon, with his three hundred archers and two hundred light cavalry, had arrived at Lazlog in less than three hours from Pazar's camp.

......Under the leadership of Toron, the hundreds of cavalry under his command swept towards Lazlog like a whirlwind, and the cavalry howled loudly while waving their swords on the back of their horses at high speed.

The panicked Germanic peasants tried their best to run to the city gate, at this time Toron had already led his troops to chase over, the defenders on the city gate tower saw the peasants chasing behind a large force of cavalry, frightened, a middle-aged man with a big sword in his hand screamed: "Close the city gate, close the city gate quickly!" ”

"No, we still have a few hundred people who haven't come in, if these people fall into the hands of the Huns, it will be a dead end, let them in first and then close the city gate!" A sturdy young man spoke out against it.

The middle-aged man turned his head, suddenly reached out and grabbed the young man's chest clothes and pushed him against the wall battlements and said viciously: "If the Huns are allowed to rush into the city, we will be finished, there are only a few hundred people outside the city, but there are thousands of people in the city, I know how to choose, now I am the supreme commander here, I have the final say, although you are Odoase's cousin, but if you hinder my command, I will kill you, pass my order, close the city gate immediately, send someone to inform Odoase, and say that there is a large force of Hun cavalry under the city."

Valdoru gritted his teeth, and had to carry out the order of the middle-aged man, shouting loudly under the city gate building: "Close the city gate, close the city gate immediately!" ”

When the Germanic soldiers at the gates heard the order, dozens of them pushed the two heavy gates up and shut, and the gates creaked and creaked, and the peasants outside the gates rushed madly when they saw that the gates began to close, screaming heartbreakingly.

The city gate was finally closed, and there were more than 200 peasants who were locked outside the city and could not enter, the Hun cavalry behind them came at a gallop, sporadic arrows shot forward from the rear, and the peasants were constantly shot to death and fell to the ground, the sound of horses' hooves was like the call of the god of death, and the peasants who were still running frantically to the city gate were urinated.

The peasants who had already run under the city gate but could not open the city gate were in desperation, so they could only flee along the foot of the city wall to the east and west sides, and waiting under the city gate was undoubtedly a live target for the Hun cavalry, and there was still a little chance to survive if they dispersed and escaped.
