Under the repeated urging of Emperor Jing, Liu Che finally completed the trial production of a small amount of special Turner explosives before the first spring rain came. In order to show the power of high explosives to the emperor's father, Liu Che even stopped the production of several glass cellars, and did not hesitate to burn hundreds of stones of cement by hand, and the quality was not inferior to the ordinary cement of later generations.

In the school grounds of Yulin Camp, two strong walls have now been erected. Among them, the yellow-brown high wall of dozens of zhang long, all made of loess rammed, four zhang high, five zhang wide (thickness) of the base, completely imitated the wall of Chang'an City; The other light gray low wall, which is only ten zhang long, is a cement concrete wall repaired by the "royal" masons on the prince's Zhan Shi's mansion. Due to the limited amount of cement, the height and width of the cement are only two zhang.

From a distance, the cement wall is several times smaller than the loess wall. Emperor Jing stood on the school platform, listened to Liu Che's explanation with great interest, stroked his beard, and asked: "According to the emperor, that small cement wall is much stronger than the wall of Chang'an City?" ”

Facts speak louder than words, Liu Che had long expected that the emperor's father would be interested, and he deliberately asked people to make a cement pier next to the school platform. He pointed to the long-handled copper hammer on the weapon rack of the school platform, and said with a confident smile: "If my father doesn't believe it, let people try it." ”

Emperor Jing bowed slightly, and ordered the guards behind him: "Yan Ben, you go and try!" ”

Yan Ben, who had a tiger's back and a bear's waist, bowed down to his promise, took a large copper hammer weighing dozens of catties, and walked off the school platform quickly. When he came to the cement pier, without saying a word, he held the copper hammer high with both hands, smashed it with a bang, and jumped out a few sparks. The people who couldn't reach it only felt a buzzing sound in their ears, and then looked at Yan Ben, but their faces were pale, and they stood frozen on the spot.

Yan Ben is worthy of being a dead soldier cultivated since childhood, although he has been injured by the huge force of the earthquake, he quickly recovered his appearance, dutifully inspected the cement pier, and saw that it was only peeling off the shallow skin, and then returned to the school platform, bowed to Emperor Jing and said: "Your Majesty, that cement is indeed a little harder than a rock!" ”

"Take good care of your injuries, you're not too young, don't be so reckless in the future!" Emperor Jing patted him on the shoulder, these people around him were all henchmen and guards who had followed him for many years, although the monarchs and ministers were different, but there was some friendship.

"No!" A trace of emotion flashed in Yan Ben's eyes, but he didn't say anything more, and silently retreated behind Emperor Jing to stand still.

Liu Che was envious in his heart, the era of imperial power was really bullish, and there were really few such die-hard people in the future.

Knowing his son Mo Ruo's father, Emperor Jing saw his son's big eyes dripping and rolling, how could he not see his ghost thoughts, patted his little head, and said with a smile: "Go back and ask Wu Cheng to find a few dead soldiers for you." ”

"Thank you, Father!" Liu Che was overjoyed when he heard this, and Lang Zhongling Wu Cheng was the head of the emperor's father's bodyguard, in charge of many dead soldiers, and only obeyed Emperor Jing's edict. Ping said that even if Liu Che wanted to ask him for a few people, he would not give face at all.

Emperor Jing waved his hand disappreciatively, and asked with a little reproach: "This Laoshizi cement is so strong, it is the most suitable for building a city and walls, why didn't the emperor offer it earlier?" ”

Liu Che shrugged his shoulders and said helplessly: "It's not that the ministers are hiding their secrets, it's really that the cement costs too much." That low wall alone cost hundreds of thousands of dollars, enough to ram a side plug out of loess. ”

Emperor Jing suddenly agreed: "If this is the case, I have to give up." ”

"However, Erchen has some methods, using lime, slag and sand and gravel to make a triple soil, although it is not as strong as cement, but it is far better than the clay soil used by the Qin Dynasty to build Chidao and the Great Wall, and it is enough to build fortresses and side walls."

Emperor Jing's eyes lit up, and he became interested: "Oh? The clay method of the Qin Dynasty has long been lost. I only know that it is made of lime, glutinous rice water, ginger juice, plant ash and other auxiliary materials, and the emperor can actually make building materials stronger than it? I don't know if it will cost much? ”

Liu Che said confidently: "They are all commonly used cheap things, and the cost is very small, which is slightly more expensive than rammed loess walls." When Zhou Yafu returns to the dynasty and resumes his life, his sons will sacrifice their own prescriptions. ”

Emperor Jing was stunned when he heard this, and immediately showed a knowing smile: "The emperor is reasonable, and when Zhou Yafu handles things well, he will have no worries." ”

Liu Che didn't say more, but gave a few words to Gongsun He, the commander of the Yulin battalion behind him. Gongsun He received the order and led a few Yulin guards to the ten siege ballistas placed outside the front of the school platform, and carefully inspected them.

The siege carts were now all wound, their heads raised high, and the thigh-thick straight bolts pointed into the sky. The arrowhead is made from a hundred steels smelted in an iron-smelting workshop, and it is sharpened to a very sharp point that shines in the light. The wooden arrow shaft is covered with some long strips of cloth, and a long fuse rope is connected at the end.

Gongsun He looked at the cloth bags with scruples, and he knew that they contained Rausch high explosives. Since some time ago, His Royal Highness the Crown Prince built a small courtyard in the Yulin Camp to make high explosives, and he finally followed His Royal Highness the Crown Prince and watched His Highness guide the craftsmen to concoct these slimy things.

At first, His Highness would enter the courtyard from time to time to give guidance. However, when the high-explosive was about to be made, His Highness did not allow Yu Linwei to step into the courtyard, and only allowed a few craftsmen who signed life and death certificates to enter, and His Highness himself did not even take half a step around the courtyard at all.

Gongsun He mistakenly thought that His Royal Highness doubted Yu Linwei's loyalty, and once risked his life to ask, but listened to His Highness's faint reply: "There was once a craftsman named Nobel, who was killed by a fist-sized ball of explosives!" Now that there are several stone explosives in the yard, do you really want to go in? ”

Gongsun He was skeptical, but he didn't ask again. Until the explosives were finally made, His Royal Highness the Crown Prince specially ordered someone to take out a small jar and test it in front of the entire Yulin Battalion soldiers. After seeing the power that only the gods have, Gongsun He finally understood why His Highness was so afraid, this was really a dangerous thing that should be kept away.

Since then, he has been afraid of high explosives, because His Royal Highness has repeatedly instructed that since there is no "tranquilizer" for Rausch, this high explosive will not only explode when it encounters fire, but even if it collides violently, it may detonate, which is extremely dangerous. Even the crossbow arrows that are said today were installed by those craftsmen who risked their lives to install them carefully, and Yu Linwei did not handle them at all.

Gongsun He received an affirmative reply from the craftsmen, breathed a sigh of relief, and let the Yulin guards take over the control of the crossbow cart, and then waved the flag in his hand a few times at Liu Che on the school platform.

Seeing this, Liu Che bowed to Emperor Jing and said: "Father, everything is ready, I'm afraid there will be a big movement at that time, and I ask my father to take precautions as soon as possible." ”

Emperor Jing waved his hand with interest and said, "I have already ordered Wei Wei and Lang Zhong to send people to strictly guard the palace gates. The palaces of Miyagi have also been informed that there will be no mistakes. ”

"Erchen is not worried about this, but I am afraid that the noise will be too loud and frighten my father." Liu Che helplessly explained that the emperor's father was unreliable, and in order to be able to personally test the results, he ignored Liu Che's bitter advice and arranged to test high explosives in the palace.

Emperor Jing said with disdain on his face: "I am the son of heaven of the Han Dynasty, protected by heaven, what else can surprise me?" ”

Liu Che's head is full of black lines, I will also be the emperor in the future, where is the bullshit Tianwei protection? Seeing the emperor's father with a proud look on his face, Liu Che sighed helplessly, turned around, and raised the order flag in his hand.

Gongsun He Deling shouted a few times. The Feather Forest Guards, who had practiced countless times, lit the fuse with torches, and the crossbowmen immediately pulled down the frame. With a roar, the crossbow arrows shot out with a sharp roar, drawing a long arc and shooting towards the two city walls dozens of feet away.

"Hurry back!" Gongsun He shouted, the Yulin guards who had been prepared for a long time, ran backwards, they had all seen the power of high explosives, and now the explosives of several stones exploded at the same time, and the splashed rubble in the sky could definitely smash them to death! It wasn't until they ran dozens of feet away and came to the shield array raised high by more than 100 Yulin guards that they breathed a sigh of relief.

At this time, the ten crossbow arrows had slowed down, and they slammed into the two walls from the air. A moment later, the earth-shattering loud noises sounded one after another, like a flat-bottomed thunderstorm, and the entire Chang'an City seemed to shake slightly. On the school field of Yulin Camp, there was smoke and dust in the sky, flying sand and rocks, and from time to time there was a dull sound of heavy objects hitting the ground. The two city walls, which are faintly visible, have long been dilapidated.

It was night, and the frightened Emperor Jing sat in the imperial study of Weiyang Palace, staring at the crown prince Liu Che with a little shame, and said fiercely: "Does the emperor want to deliberately watch my jokes?" ”

Liu Che said with an innocent face: "Where did my father say this, he really wronged his son!" Erchen has repeatedly reminded you, Yan Ben, all the guards can be witnesses! ”

Emperor Jing knew that he was unreasonable, and snorted coldly: "I hope that before I am stung, I can see ten explosives workshops to make high-explosive charges for the use of the army in Heshuo within the year." ”

Liu Che frowned, thought for a moment, and said with a serious face: "Nowadays, the nitrocellulose and ** used in high explosives are very unstable, and it is very easy to have a powder magazine explosion. As a last resort, Erchen was reluctant to let a large number of craftsmen risk their lives to make it, and transportation and storage were a big problem. After all, high explosives are different from black powder, and the secret recipe must be kept strictly secret, and it is impossible to fake it. Now that there is a shortage of talent, this is not the time to risk human lives. ”

Emperor Jing rubbed his brows, and had to agree with Liu Che's opinion, after all, he made the high-explosive charge, so he naturally had the most right to speak. After pondering for a moment, he asked with a little reluctance, "Isn't there any other way?" This high explosive is really a godsend, and it would be a shame to abandon it. ”

Liu Che couldn't help but breathe a sigh of relief when he saw that the emperor's father was as good as a stream, and said with a smile: "It's not that you don't abandon it, your son can first concoct all kinds of raw materials in the Yulin camp." When the army set out for the battle, send Yu Linwei and craftsmen to escort them, and then deploy explosives on the spot, so that it is both safe and secretive. ”

Emperor Jing was overjoyed when he heard this, and praised repeatedly: "It's still the emperor who thinks about it thoroughly!" It is worthy of my blood and bones, and it has the style of being a father! ”

Liu Che pursed his lips, slandering in his heart. In fact, Liu Che didn't care too much about special Bednar explosives. He had the time and patience to wait, to plan.

With the continuous improvement of the process, it will be possible to produce ether and pure ethanol in the future. At that time, the nitrocellulose will be dissolved in ether and ethanol, an appropriate amount of stabilizer will be added to make it gum, and then pressed into flakes, cut into strips and dried and hardened, and smokeless gunpowder can be made.

Smokeless gunpowder has no residue after combustion, and no or only a small amount of smoke is emitted, but it can make the range of the projectile, the ballistic straightness and the shooting accuracy all be born, providing the conditions for ammunition. The Maxim heavy machine gun, which was famous for later generations, was able to have practical value precisely because of the use of smokeless gunpowder. At that time, the Han army will surely sweep through Europe and Asia, and no one will be invincible!
