During the Spring Festival this year, although Li Yong's family was neat, they were not very happy, because they lost a close friend, and Cheng Chuliang did not return to Chang'an, but accompanied Aunt Li and his sister Li Yan in Xishan, and he also took Pei Qing over for the New Year, because he promised to take care of Pei Qing, and he also regarded Pei Qing as his sister-in-law.

"Big brother, happy New Year, this is what I learned in our Xishan, everything is fine at home, my mother goes to the field to see for a while every day, my little sister has also entered the high school of the university hall, and her studies are very good, my sister-in-law has not returned to the opera troupe, but she misses you too much, and her spirit is a little bad, but don't worry, I will take care of them, and I will be able to avenge you soon, Brother Xue has issued an order for combat readiness, and now we have 10,000 troops, and I will not let go of any of the wild people who killed you."

Cheng Chuliang sat in front of Li Tiezhu's tombstone, he poured a glass of Xishan's first-line wine, he knew that Li Tiezhu didn't drink, but he didn't know how to sacrifice the dead, so he learned the same, as he said, when Tuyuhun gathered troops, Datang was in action, Xishan was also in action, the black army expanded its strength to 10,000, it was 10,000 combat troops, and the weapons were also upgraded, so the black powder of the musket was replaced by more powerful yellow gunpowder, which could only shoot effectively at a distance of 100 meters, and now it is directly raised to 300 meters. Yellow gunpowder is also known as bitter and sour taste, the power is ninety times that of black gunpowder, and yellow gunpowder is relatively stable, friction, shipment and even open flame can not detonate it, mainly when it is very dangerous, because there is a main chemical in it, Xiaohua glycerin, this thing will explode if you touch it casually, when studying yellow gunpowder, the research room has exploded several times, fortunately, Li Yong reminded them, so there were no casualties, otherwise Li Yong would have to die of distress, he finally cultivated a precious talent, was blown up by himself, there is no place to cry, when Nobel made yellow gunpowder, he killed his younger brother and assistant, although Li Yong does not use chemistry, but after all, he is a super student with a double degree in science, he knows that the synthesis of yellow gunpowder is actually a mixture of Xiaohua glycerin and diatomaceous earth to form granules, smokeless when burning, almost no residue, and also avoid the trouble of frequently cleaning the barrel and chamber, so it is also called smokeless gunpowder. The power of gunpowder is greater, the durability of the barrel will decrease, the previous barrel can be fired hundreds or even hundreds of times in a row under normal use, but if smokeless gunpowder is used, it can only be shot twenty or thirty times, for a fierce battle, this is fatal, for those cavalry on the steppe, there are many people, you can put twenty guns alone, you can't win at all, so the transformation of the barrel is also imperative, because there is no good power, you can only rely on water power, the lathe can not play a tenth of the role, Not to mention any stamping direct work, if it can be done, Li Yong will directly do the rear loading rifle of later generations, fortunately, the researchers have exerted their wisdom, because the energy of smokeless gunpowder is much higher than that of black powder, if the recoil generated according to the original charge will be difficult for the firearm and the shooter to bear, so they reduced the caliber of the projectile to 8 mm, the speed of the bullet in the barrel is higher under the impetus of smokeless gunpowder, and the full lead bullet is easy to wear and fill the rifling, which is difficult to clean, In addition, considering that the future will be fed with a tubular magazine, the future bullet will have a primer, so the researchers left a hand, after some revisions and modifications, the Xishan eight-millimeter bullet was born, the first test firing, everyone was shocked by this powerful recoil and destructive power, the previous 100-meter shooting is simply by luck and intensive shooting, 100 meters to the enemy wearing heavy armor is not much damage, the effective range is about 60 meters, If it is a cavalry, they are dangerous, now this new musket is constantly more accurate, a hundred meters as long as you aim and shoot, almost can easily hit, and even the strongest defense of the Xishan helmet can not resist, what is even more terrifying is that the live pig wrapped in the Xishan helmet was penetrated by eight millimeters of copper lead bullets, and the body was directly blown into a big hole, that is to say, there is a blood hole in front of it, but looking at the back is a big hole, and the effective distance of the new musket is three hundred meters, Even if you wear a Xishan helmet and are hit at a distance of 300 meters, although it will not kill but will lose your combat ability, the range of 200 meters can be said to be a direct death, in the naming of the new musket, or the old rules are applied, but this new musket is made in the ninth year of Zhenguan, so the new musket is named Xishan nine type, with the completion of the musket, the shell of the artillery has also been modified, mainly the change of the explosive bomb, with yellow gunpowder, the original chicken rib explosive bomb directly became the favorite of the army, an explosive bomb past, There is no live mouth within a range of five meters, and the firing range has directly become five kilometers, the army has also returned all the small-caliber artillery, directly using large and medium-caliber artillery, and their grenades have also been upgraded, theoretically speaking, the current 10,000 black army, there is no problem at all to destroy Tuyuhun, but the war is not calculated in this way, as a night walker of the Tang Dynasty, Li Yong's black army has always adhered to the purpose of acting secretly. Li Yong's side has completed the equipment upgrading and personnel transfer before the Chinese New Year, and the recruits have almost completed the training, and now they are just short of actual combat, but under the leadership of many veterans, the problem is not very big, mainly because of the skilled use of new weapons, with rifled muskets, you can no longer use the previous tactics, and the new tactics will change accordingly, so Xue Rengui is very busy, and he is in the office during the busy New Year, constantly changing the tactics that have been written. And Li Yong's father-in-law ordered the last court meeting in the eighth year of Zhenguan to send troops to clean up Tuyuhun in the spring of March next year, of course, there are many objections, or the same old three, what treasury has no money, what belligerent will die, what people are bitter, etc., but Li Er directly put Fu Yun's 100,000 army has been assembled, ready to attack them, it was a stinking scolding, and finally those ministers who opposed it shut up directly, and then it was to select the generals, Li Jing became the general manager of the Xikaidao march, the commander of the military department Shangshu, and the head of the Jishi Road march, Hou Junji, Shangshu Ren Chengwang of the Criminal Department, Li Daozong, the head of the Shanshan Road March, Li Daliang, the governor of Liangzhou, Li Daliang, the head of the March of the Last Road, the governor of Minzhou, Li Daoyan, the head of the Chishui Road March, Gao Yongsheng, the head of the Yanze Road march of Lizhou, and the Turks of the Tang Dynasty and He Li of Qibi attacked Tuyuhun.

"Everything is ready, when will the imperial court send troops to Tuyuhun?"

Li Yong was cooking Chinese New Year's Eve meals in the kitchen while asking Zheng Liwan, who was helping him.

"In March after the beginning of spring, do you really want to go?"

Li Yong took Zheng Liwan's washed vegetables and poured them into the pot and began to stir-fry.

"I have to go this time, not only for those who can't come back, but also to investigate these things myself, don't worry, everyone will go with me this time, and it will be fine."

This time Li Yong decided to personally lead the team, the original warm Chinese New Year's Eve dinner because Li Yong was going to go on the expedition, the atmosphere became very depressing, no woman is willing to lead her man to the expedition, Li Tiezhu is an example, they can't bear such consequences, but they all know Li Yong's character, when he decides a thing, no matter how difficult it is, he will do it, and Li Tiezhu is his friend, this revenge, Li Yong must personally revenge, so they can't stop it.

"Today is Chinese New Year's Eve, the first glass of wine, we first toast Tie Zhu and the other brothers."

Li Yong picked up the wine glass and sprinkled the wine in the glass on the ground, Changle and the other women did the same, and then Li Yong poured himself a glass of wine again.

"This glass of wine is for my ladies and gentlemen, thank you for your continued tolerance and support to me."

Then he drank the sweet fruit wine in one gulp, and then he poured another glass.

"The last cup is to honor us for our victory, and our future life will be better and better."

Three glasses of wine ended, a strong smile of the Chinese New Year's Eve dinner began, although it was only a very low degree of fruit wine, Li Yong was also drunk, he dreamed of everything in the afterlife, the ship research institute that he was busy working all the time, those familiar and strange colleagues, and then dreamed of those sacrificed black army soldiers, dreamed of Li Tiezhu, in the dream he shed tears that he endured for many days, on the first day of the new year, Li Yong got up early, with the help of Changle, put on the Xishan helmet that he had not worn for many years, Li Xueyan put on the helmet for him, Zheng Liwan hung the black knife symbolizing the black army into the belt around his waist, after Li Yong put it on, he hugged and said goodbye to all the women one by one, Changle saw Li Yong wearing armor, and the black cloak behind him floated up with the wind and left, she had to endure the pain of separation again, and endure the fear of her husband going to the battlefield. Li Yong got on the battleship of the coastal patrol and left the Huating Naval Base, the battleship secretly entered the sea, drove into the Beijing-Hangzhou Grand Canal, and then turned into the Yellow River all the way to the west, and then arrived at the Weishui Wharf outside Chang'an City, Xue Rengui, who had been waiting early, picked up Li Yong and rushed back to Xishan, Xishan Valley, which had not returned for many years, Li Yong looked at this clean courtyard, although he no longer lived here, but his parents lived here, in order not to worry his parents, he looked at it from a distance and then went directly to Xishan Camp, As the Marquis of the founding county and the county commander of Huating County, he is also the commander of the maritime yamen, and he can't leave without the emperor's edict, so he has to keep a low profile and can't let others catch him.

"It's been a long time since I've been back, and the Xishan Camp still hasn't changed much from before."

"Commander, in fact, it has changed a lot, the camp has been expanded twice, and now in addition to 10,000 combat troops, there are 3,000 logistics support troops, and the ghost special combat team has also expanded from 100 to 500 people, and the hardware equipment in the camp has also been improved a lot."

"I don't worry if you are in charge of the Xishan camp, that kid is okay?"

"Well, it has been adjusted, I completed the assessment of junior officers some time ago, and now I am the acting platoon commander."

Xue Rengui introduced everything in Xishan Camp to Li Yong, who had not come back for a long time, and Li Yong walked on the familiar road while listening.

"Rengui, how long have we known each other?"

Xue Rengui was a little confused by this sudden jumping question, but he still replied.

"It's been four years, why did the commander suddenly ask this?"

"It's nothing, it's just a sudden reminder, just ask, the recruits have all finished training, right?"

"I have completed the training of recruits, but I am not skilled enough in the use of the Xishan Type 9 musket, but with veterans, the problem will not be very big."

Li Yong nodded and continued to walk towards the office building he was familiar with.

"This time I came back in secret, so I don't want others to know, after the third day of the Lunar New Year, the fourth day of the new year the whole army is ready, the fifth day of the new year to take the navy warship along the Yellow River westward, this channel is discovered by the people of the intelligence bureau, enough for us to leave unnoticed, and then land near Lanzhou, Fu Yun's bullshit army According to the intelligence, his first target is Weizhou, Weizhou city defense is not high, and there are not many defenders, so I will ambush them in Hezhou before Fu Yun comes to Weizhou."

Li Yong sat in the original combat conference room, which was already full of people, Li Yong told them his battle plan on the map, and all the senior officers kept recording it in their notebooks.

"This expedition, I personally commanded, Xue Rengui as the deputy commander, except for the troops left behind, the rest including the logistics support troops, all the staff dispatched, our combat purpose is that as long as there are Tuyuhun people with weapons and horses, not a single one will be left."

"Yes."

After Li Yong's clear battle plan and requirements, those senior officers began to operate, constantly improving the battle plan and arranging materials, calculating the amount of ammunition, just after the third day of the Lunar New Year, Cheng Chuliang said goodbye to Li Damiang and Li Yan, and returned to the Xishan camp, and the rest of the soldiers who went home for the New Year also returned to the camp on time one after another, as the acting platoon commander Cheng Chuliang received the company's order and began to rearm his troops, and the entire Xishan battalion began to get busy, and it took only one day to complete the assembly and preparation. The logistics support troops smuggled all kinds of materials to the Weishui wharf early, because it was winter, there was not a single ship at the Weishui wharf, but now hundreds of warships docked at the Weishui wharf, these are Li Yong's naval warships, Li Yong's black army and navy play dark Chen Cang, the people of Chang'an City are still immersed in the joy of the Spring Festival, the black army's materials filled one battleship after another, and those warships loaded with supplies and artillery ammunition quickly left the dock and sailed westward, and then the spare warships were filled, The Xishan battalion left the camp one after another, and then boarded the navy's warships, and those battleships full of black troops left the dock directly, and the entire western Yellow River channel was covered with warships, and those frozen rivers were directly broken through the ice by the battleships' steel collision angles, which was unthinkable to everyone, because in their concept, it was impossible for a boat to run on the frozen river in winter, and Li Yong let them see it, and when they saw the battleships on the shore like breaking bamboo, they all dared to believe that the ice was knocked open. I can't help but wonder what this fleet is doing, the fleet soon arrived at the border between Datang and Tuyuhun, because Datang does not have strong control over the waters, so the fleet easily left the border of Datang with the black army and weapons and equipment, and entered the hostile Tuyuhun, the first to arrive was the battleship loaded with material weapons, under the protection of the Marine Corps, a door of artillery and guns and ammunition was transported off the ship, Lanzhou originally did not have a wharf, but the intelligence bureau found a suitable place to build a wharf on the outskirts of Lanzhou, and established a simple wharf, This place is far away from Lanzhou City, and it is winter again, so there is no need to worry about being discovered by the Tuyuhun people, the battleships that have unloaded the supplies withdrew from the dock and hid according to the place provided by the Intelligence Bureau, because they also had to shoulder the task of covering the retreat of the army, and the follow-up battleships continued to arrive at the assembly point, and after a pair of black troops got off the boat, they began to receive their own weapons and equipment, and the artillery wiped their beloved artillery, and the black army that was divided into pieces completed the assembly on the day of the Lantern Festival, and the warships of the navy all withdrew from this water area and hid separately, Li Yong is wearing a Xishan helmet, wearing this black knife and a broken fire gun around his waist, because the weather has not warmed up, he wears this warm woolen sweater and thick down jacket in the armor, simple down jacket, Li Yong still will, it is nothing more than the surface can not be waterproof kind of fabric, but there is no problem with keeping warm.

"Rest for a day, defeat Lanzhou City tomorrow, it's too cold here, it's better to go into the city to rest."

Li Yong baked this charcoal fire in the tent to keep warm, the temperature in the northwest was not generally cold, so he couldn't stand it, so Lanzhou City suffered, all the black army received tomorrow to attack Lanzhou City, Cheng Chuliang wiped his Xishan Jiu style with a cloth, and the barrel was also stained with gun oil and carefully wiped, and then kept under the candle fire to see if there was anything that was not wiped clean, and the clean musket He took it and aimed it in the direction of Lanzhou City, and thought silently in his heart, big brother, I will attack Lanzhou City tomorrow, and the time to avenge you has begun, I want to use my musket and long knife to kill the Tuyuhun and Tubo people who killed you, the other soldiers and officers are busy with their own affairs, some are the same as Cheng Chuliang, and some are like Cheng Chuliang's previous squad leader and tell stories to the soldiers in their own class, and some are discussing tomorrow's tactical play, anyway, the black army reappeared, and sending troops to Tuyuhun to attack Lanzhou City was their first battle out of the rivers and lakes, and it was the black army with stronger weapons and equipment and more troops, and the black demon of the year was back, came back to find them for revenge, and Li Er, who was far away in Chang'an, and the generals who were going to go to Tuyuhun had just left Chang'an City after listening to Emperor Li Er's tirade.
