Zhao Yun and Ma Dai led hundreds of foot soldiers, holding part of the grain and arrows, and went north from Jiameng to aid Baishui Pass, the straight-line distance between the two places was only one hundred and fifty miles, but the West Han River (Jialing River) looped and twisted, and the plank road also followed the waterway, and the actual distance exceeded three times and more, and it took four days in a row, which was worthwhile. Previously, he had also encountered an envoy sent by Zhang Shao to Jiameng to report the emergency, saying that the Wei people had arrived at the pass and attacked day and night, and the soldiers were very damaged, and the arrows were probably insufficient, and he hoped that the prince would reinforce as soon as possible.

Zhao Yun is stationed in Shuzhong, and has been in Chengdu, Hanzhong between the back and forth several times, for the Baishui Pass terrain of the danger to have a deep understanding, he is afraid that Ma Dai is often in Wudu, do not know the geography, so Shao said: "The pass is built by the wall, the coherent plank road, the sky is dangerous and majestic, and it is really the most." The enemy came from the north, there was no flash to move around, but the frontal attack was a way, the plank road was narrow, and the attack was only about 200 people, if the crowd was tired, they did not dare to set fire. The former Zhang Shao reported that Cao Wei's former army was about four or five thousand, and there were eight hundred soldiers in the pass, which was invincible. But it is difficult to break the law in 100 days. ”

Ma Dai reminded him: "Zhang Shao is not familiar with the battle formation, and he cannot be compared with his father, but the Wei people will be able to do it." The country is not in danger in Germany, and it will not be brave in the plan, if Zhang Shaoguo can keep this, the prince will not order us to come. Zhao Yun nodded and said Bozhan You said well, so I was anxious along the way, and I was afraid that I would be half a step late. But fortunately, the destination is close at hand, and it is estimated that we will be able to enter the customs this afternoon and take over the command of Zhang Shao -- with you and me, we will not let the Wei people break through the pass.

As soon as the words fell, he suddenly saw thick smoke rising from the direction of Baishui Pass in front of him, and the second general couldn't help but be shocked: "It has nothing to do with it?!" As Zhao Yun said, Baishui Pass is connected to the plank road, so neither the offensive nor the defending sides dare to set fires. According to the reason, whether it is burning the cooking and cooking. Or point to the beacon. It won't cause such thick smoke, unless the level is broken, Zhang Shao is desperate, and takes the initiative to set fire to the pass, and even burns the plank road, trying to block the enemy's momentum......

Frightened, he quickly accelerated his progress and did not go far. Sure enough, I met my own defeated soldiers. Zhao Yun hurriedly asked, "Is it broken?" Where is General Zhang? The defeated soldiers all looked like earth, and stammered: "The Wei people also cast demon spells, and the guards are dead, and the white water has fallen!" Zhao Yun and Ma Dai looked at each other, each in horror.

It turned out that this was the day after Xun arrived at the pass, and after the morning meal, Zhang Shao, the general of the Baishui Pass, immediately encouraged his soldiers, each with his own equipment, and guarded it tightly, waiting for the attack of the Wei people - according to the usual practice. It won't be long before Cao Zhen will launch the first round of the day. At this time. Suddenly hearing the noisy drum music under the gate, the Shu army couldn't help but be stunned when they heard it, and said that if they want to attack, the drums are enough, why do they still want to play music? Could it be that Lord Cao Wei is about to arrive? But even if the emperor is there in person, there is no reason to play instrumental music on the battlefield.

Zhang Shao put his hand on the awning, raised his eyes, and saw the Wei army lined up left and right at the wider part of the plank road, and a person came out in a cluster. This man is dressed strangely: he does not wear a crown, his long hair is scattered, his forehead is wiped with yellow silk, and a long pheasant tail is inserted on the left and right; Wearing a yellow long coat, the placket is not tied, and it is blowing in the wind; stomping, without shoes and socks; The left hand holds a seal, and the right hand holds a long sword.

Immediately, a few soldiers shouted: "It's the head of the big sacrificial wine!" ”

Zhang Shaoxin said that what is the head sacrifice wine? Then he called a soldier who was shouting and asked. Xiao Bing explained: "In the past, the master ruled Hanzhong, the Taoism was widely distributed, and in Jiameng and Zitong, those who were profound in Taoism were used as sacrificial wine, and those who led the people and could live the dead and spread clouds and rain were called the head of the great sacrificial wine...... To put it bluntly, this is the outfit of the "Zhitou Great Sacrificial Wine" of the highest level of teachers below Zhang Lu of Wudou Midao.

Zhang Shao asked in surprise: "Is there anyone who is incapable of casting demon spells?" The pawn's face was like earth, and he nodded again and again. Zhang Shao himself was skeptical, but he still admonished and comforted the soldiers: "Don't get close, then the law will not be used!" ”

Looking at the "Great Sacrifice Wine" more than a stone's throw away from the juncture, he stopped and opened his mouth to say something, because the distance was too far to hear clearly. But then the Wei army gathered around him shouted together, faintly, and drifted over with the wind, probably a few words:

"Shijun is in Luoyang today, and he is a guest on the throne of Wei Tianzi, so Wei and Shu thieves will make the high disciples help him...... Immediate surrender can avoid death...... If you don't obey the order, the five fire ghost soldiers of the Great Sacrifice Wine will be taken...... All the Shu people will be eaten together! ”

To say that Zhang Lu's five buckets of rice Dao, its birthplace is Sichuan, and later Liu Yan instigated the north to take Hanzhong, which expanded greatly in Hanzhong, almost creating a religious kingdom. Although Liu Zhang turned against Zhang Lu after coming to power and banned the spread of his Taoism in the territory, there are still many people in various places, especially in the area near Hanzhong, who believe in private. And even if they don't believe in the Five Buckets of Rice, the Shu people have always worshiped witches and ghosts, and most of them believe that Zhang Shijun and his disciples and sacrificial wine are all indeed demonic. So when they heard this, most of them were frightened, and a few of them were particularly timid, or those with the strongest superstitious thoughts, and they directly held their heads and shrank down towards Guancheng. Zhang Shao held a long knife in his hand and beheaded two people in a row, so that he could barely stabilize people's hearts again.

The Wei people shouted for a while, and saw that the Shu people had no intention of surrendering, so the "Zhitou Great Sacrifice Wine" stepped on the plank road, brandished swords and seals, and posed in various strange postures, and then a thick smoke rose behind him. Zhang Shao stared at it, and said in his heart, Is this really a demon law? Or set fire to smoke to confuse me? But did the Wei people really dare to set fire to the plank road?

Just as he was in doubt, he saw a gust of wind rise, and the smoke rolled straight towards the close. Zhang Shao took a step back slightly, feeling that the smoke was very choking, and couldn't help but cough loudly - the coughing sound next to him also came and went. Zhang Shao hurriedly shouted: "Be on guard, don't let the enemy take advantage of the smoke to attack ......" but he couldn't shout anymore after only half of the words, he only felt that his throat was on fire, and then blood was dripping from his nose.

A Shu pawn shouted: "Ghost soldiers, ghost soldiers are coming!" I saw that in the thick smoke, countless ghosts suddenly poured out from around the body of the "Great Sacrifice Wine", all of them with eyes like copper bells, faces as red as blood, fangs turned out, colorful side cards in one hand, and knives in the other, swarming. The Shu soldiers were all horrified, rushing to each other, and Zhang Shao couldn't stop. Zhang Shao was anxious, what kind of ghost soldier did he say, I will shoot one, and you will know that it is false. Immediately took the bow, mounted the arrow, aimed at the front of the "ghost soldier", that is, shot the arrow fiercely......

But his hand was soft at this time, and the arrow only flew more than ten paces away, and then it drifted with the wind, and he didn't know where it went. Immediately, those "ghost soldiers" rushed to the front of the pass and climbed up...... Zhang Shao was still about to draw his knife to resist, but was blocked by a "ghost soldier" horizontal card, he stumbled and stood unsteadily, and actually planted his head in Guancheng and fell straight into the turbulent water of the Western Han Dynasty......

The whitewater danger was broken.

Of course, there are no demon laws in this world, and there are no ghost soldiers, these are all small tricks that Xun plays. In a sense, this is thanks to the memory of his previous life, in the society at that time, all kinds of ancient folk arts and storytelling were originally mixed with a lot of gods and ghosts, and under the influence of the political environment, most of them were revised with a "materialist worldview" when he was a teenager. Performers often spend a lot of space to describe the so-called Zhuge military division stargazing and borrowing the wind, scattering beans into soldiers, in fact, they are all using the superstitious ideas of the people of the time to engage in tricks, how he was assigned, how to put on makeup, how to release smoke to create an atmosphere......

But at first, he didn't think of it. On the same day, he deliberately set fire to the pass, but Cao Zhen directly rejected it, and he was not very willing to do it - the wind direction is so good, isn't it too much to let the fire go? So I asked Frustrated, and Frustrated Zifu said, although we can't set fire, but "all the governors come to the world, or they can be used."

What is the reason for the honor? In fact, to put it bluntly, it is the gunpowder weapon that he has always valued.

On the one hand, there was no leader in the development of gunpowder weapons, and secondly, Taoist Xie had not produced results for many years, and Cao Cao gradually lost confidence and interest in this new weapon, so he simply stopped doing a special job, and left it to the Ministry of War. The heavy responsibility of the development and development of gunpowder weapons fell to Zhuge Kongming, but Zhuge Liang didn't know much about it, so he had to come to ask the teacher Shixun for advice - this thing was originally made by you, how to continue to study it now, or stop at the original foundation, you have to help me get an idea.

Shi Xun said don't think that you and Ma Jun can study machinery in order to produce heavy weapons for the military, in fact, the development of this gunpowder weapon will have an unlimited future - of course, even if I tell you now, you may not be able to understand it, let alone believe it. Therefore, the research and development of gunpowder weapons cannot be stopped, and I will give you a few general directions:

The first is the purification of sulfur, nitrate, and carbon, and only when the raw materials are pure enough can the highest combustion efficiency or even explosion efficiency be produced. There was once a time travel novel that as soon as the protagonist invented gunpowder, he used it to blast the city wall, which is completely nonsense, not to mention that the traditional black powder is basically incendiary rather than explosive, even if it can explode, under the premise of low raw material purification technology, it would be good to be a cannon fighter, and blow up the city wall?

Second, it is to try to add other excipients to enhance the efficacy of a certain aspect of combustion or explosion, and after repeated experiments, come up with the most suitable ratio, and then try to mass production. Shi Xun vaguely remembered that there were three different gunpowder formulas recorded in the "General Essentials of the Martial Arts", and the raw materials were very rich, in addition to the basic three things, there should be wax, oil, lacquer or something.

Third, the current gunpowder is barely enough to be used as incendiary (anyway, it is more effective than other military incendiary drugs in this year), and the use of boosters and explosives is still at the level of children's toys...... It is estimated that the purification of raw materials and the refinement of formulas are not a one-time effort, so we might as well change our thinking, let's use gunpowder and do something else...... Let's say, smoke pills?

"You can try to adjust arsenic, croton, wolf venom, etc., to see how to ......" (to be continued.) )
