If someone counts what the most sections Lao Luo has experienced along the way, he will find that starting from the Asia Minor Peninsula adjacent to the Aegean Sea, passing through the Anatolian Plateau, crossing the Caucasus, passing through the entire Khorasan region, and then to the Amu Darya Syr Darya River in the north of Central Asia or the Seven River Basins (river basins) where Wuhu water kills water and killing water, and even to the vast area of the northern section of the western foot of the Tianshan Mountains at present, there are most things on this vast land except for the steppe wasteland. There are salt lakes of various sizes scattered everywhere.

What does the salt lake produce?

The most foolish people also know that it must be salt production, but the salt mentioned here is not the kind of sodium chloride crystals that people can eat, but various sulfates and nitrates, which are the basic materials of industry in later generations, but in the eyes of people in this era, they are poisons that kill people, but in the hands of soldiers like Lao Luo? They are the basis for the birth of the best thermal weapons!

Just a few very casual passes, Lao Luo collected enough nitrification for him to experiment with the synthesis of suitable materials, as for sulfur and the like, it is easier to find, Lao Luo has already gained something when he first arrived in this time and space, in addition to adding another ingredient - charcoal, all the materials are complete.

Of course, this alone is not enough, gunpowder is only an initial explosive substance, and the carrier it needs is not something that the current technology can solve immediately, even if it can, Lao Luo does not want to make them in Central Asia, the number of materials is a big limit, and secrecy is the key he attaches the most importance to. He didn't want a little negligence to become an obstacle in the future.

Even if the craftsmen in the team have returned to their hearts, Lao Luo has not leaked a single bit, and the method of frying gunpowder is only handled by a limited number of people directly under the craftsman Ge Shulie, of course, because of the limitations of materials and tools, the gunpowder purified and prepared is only the initial granular gunpowder, but this is enough.

Next is the carrier, at this time the western foot of the Tianshan Mountain is not the kind of barren in later generations, but there are countless tall trees, especially larch, drinking the newly formed ballista battalion muscular men picked and cut more than 100 pine trees with a diameter of half a meter at breast height - peeling, segmenting, breaking in half, slotting, planing a series of carpentry processes, and then the blacksmith made the iron hoop to divide the pine wood divided into two halves with arc grooves, this thing became the most primitive mortar cannon.

The final completed pine cannon has an outer diameter of about 40 centimeters, an inner diameter of more than 20 centimeters, and a length of more than three meters - not a long tube, the bottom is closed, in fact, the internal empty chamber is only more than one meter, the weight of this thing is also four or five hundred pounds, two strong men can carry it and run, and this crude mortar does not need a gun carriage or the like, just find a good firing point, dig a pit with a slope in the ground and bury it half, the propellant is available, this thing doesn't even need shells, just pebbles picked up by the water, When it was prepared in early spring, there were many experiments, and Lao Luo estimated that there would be no problem with a range of one or two thousand meters. Of course, this number is not accurate, because it is not a strict object, its walking point is very large, and it cannot be attacked at a fixed point, but even so, it is a big killer of face damage.

……

In the early morning, the cooking smoke gradually disappears, and the clouds coming down from the snow mountain dissipate together, the early sun is bright, it is said that this is a good season to play and go green, but the people at the foot of the Tianshan Mountain do not have this mind.

There are more than 1,000 families of different ethnic groups living in Polo City, most of them are the Huangjia people, in addition to the Han people, Xianbei people and steppe nomads who have fallen here, and the grassland nomads who can't tell the ethnicity, in the past half a month, since the Turks, the Qarluq people and the Dangxiang people came here, there has been no peace, although the army of the three departments claims to be soldiers, but most of the constraints on their subordinates are only in wartime, and these soldiers in Pingsuri are not taken care of at all, especially this is not the place of their own people......

It is conceivable that when they go to a place that does not belong to them, what will happen to the soldiers who have lost their restraints, bullying men and women is commonplace, and looting property is even more commonplace, and the residents of Polo City can only endure it, of course, it is inevitable to complain in private.

Another day passed, because he couldn't go outside the city to farm, Gan Laohan could only sit helplessly under the wall, looking at the Turkic cavalry passing by in the distance in a daze, the morning sun shone on his body warm, but it couldn't warm his heart - the fields sown hard in the spring were set up by the Turks, how could his family survive?

"Brother Gan, didn't you go out today?" A man with a felt hat paced over, why did he say pacing? Because the people who come are uneven, they are crippled.

"Come and sit against the wall, Bayar!" Gan Laohan waved his hand, pointed to the stone beside him, sighed and continued: "Since those black turbans and red turbans came, I have been out of the city three times, and my land is completely finished, but unfortunately the seedlings that were sown just a month ago ......"

"Be content, brother......" Bayar sat down on the stone, leaned his back against the wall, and squinted his eyes into the distance, "The black turbans and red turbans are all here to fight, yesterday I went outside to take a peek, and the group of people who fought with them were even more fierce, although they seemed to have fewer people, but the losses were the black turbans and red turbans, as well as those Xianbei people from the east......"

"Xianbei people? You mean the partymen who shaved off their heads, right? So many of them still suffered? Gan Laohan was a little surprised.

"That's right, I saw with my own eyes that thousands of dead bodies were brought back in the afternoon, and many of them were burned...... Tsk, it looks like barbecue...... I said, brother, didn't you smell the smell of barbecue all over the city yesterday? "Because of his lame leg and lack of nutrition, Bayard is as thin as a skeleton, but his eyes are still deep.

"My God, no wonder there was such a big smell of barbecue yesterday, and I thought those red turbans were doing some kind of barbecue banquet......" Gan Laohan pulled the half-draped leather jacket on his body, as if the cold air on the stone wall on his back had soaked into his body, and then asked in a low voice: "Bayar, what you said is true?" Did the red turbans really kill a few thousand? ”

"Not only that, maybe there are tens of thousands of people, but I didn't dare to go around, I just went out of the city and lay down in the cracks of the stones to peek at it a few times, where can I see so thoroughly?" Bayar said in a low voice with a bitter face: "By the way, I saw the people and horses on the other side, the flag seems to be from your Han, the armor is black and yellow, it feels weird to look at......"

No one cares about his figure and looks there, so he can take a few steps bravely, but if he can go farther away, his legs and feet can't support it.

"Are you sure? Bayar, I remember you couldn't read? Hearing the news of the Han people, Gan Laohan almost didn't jump up, looked around left and right and no one noticed, and then he asked in a low voice, as for how many people died in the red turban and black turban, he didn't care.

"Don't look down on people! I don't know how to read, but which flag has a square word on it, not a crescent flag, where do you say it is? Bayar's eyes widened, and he narrowed against the wall, but the words in his mouth still explained.

"I ...... You damn Bayar, if it weren't for the fact that your legs and feet are just a little better, I'll beat you hungry bastard! Gan Laohan clenched his fists and said a cruel word, and found that it didn't work at all, so he continued: "In the evening, it's okay to give you a good piece of bacon at night, right?" My little lady didn't want to give her a few times when she was hungry! ”

"Hey, brother, you also know that my legs are useless, and no one in the clan cares about me anymore, so there's no way to ......do it," Bayar smiled and said, just because of his thin appearance, that smile has a terrifying taste no matter how you look at it.

"The old man is too lazy to pay attention to the bad things in your clan, say it quickly!" Gan Laohan knew that he couldn't get involved in the internal affairs of the Huangsi people, so he was too lazy to talk to the bottom, for him, if it was the team of the Han people, there was hope to leave this land that no one relied on, and he would not dare to ask a word if the fields were trampled flat like now.

"Brother Gan......" Bayar really didn't dare to offend the one in front of him, although there are not many local Han people, but there are so few, and they are not young anymore, but they are really anxious, and they can kill a few with a hoe, and then they will not care about him in the clan, but they will hunt him down. With a flattering expression, Bayard continued: "You know that Gombal in the earthen house in the east has a good relationship with me, he knows Chinese characters, and he went with me yesterday, and he said that the word written on the flag is Luo, and on the flag is two characters, and on it is Dongwei, and I heard from the Qarluqs that those people came from the other side of the river, and they are very fierce...... A month ago in Bishkek, oh, you know, fifty or sixty thousand steppe riders were killed over there in the old town of Broken Leaves, and the river over there was dyed red......"

"Gombal? That guy's words also have a score...... "Gan Laohan listened to Bayar's words, but he was not in a hurry, and leaned against the stone wall to ponder, but he had never heard of the Dongwei and Luozi banners, and he was a little hesitant for a while, but he knew that even the Han people have a lot of people who kill people without blinking, and those guys don't care whether you are of the same clan or not.

When he was pondering, Gan Laohan heard someone shouting from afar, "Hide quickly, the black turban came to arrest someone and build the camp for them......"

When the old man woke up, he turned around and wanted to run home, and cursed in a low voice: "Damn! Raised by thieves, why didn't God send down thunder and kill them......"

But before he could finish cursing, he felt the ground tremble under his feet, and then a thunderous roar came from a distance, and the stone wall next to him was falling dust with a pop......

In an instant, all the people who were running around stopped and the earth dragon turned over? Or did thunder really fall from the sky? No matter what, no one dared to move again......

The thunderous noise in the distance began to resound, and the people in the four places suddenly became chaotic, no one cared about whether the Qarluqs would come over, and the thunder sounded on a sunny day, whether it was the earth dragon turning over or not, they needed to find a safe place to hide......
