The Liao soldiers came like a tidal wave, which meant that the first wave of the offensive against Xijin Province began, and the footsteps of tens of thousands of people running together converged like rumbling thunder, mixed with shouts and screams.

Zhao Zhen saw through the guards around him that the first wave of Liao soldiers had more or less some things in their hands, either ladders and planks, or sandbags and branches, which were probably used to fill in the ravines outside Jinfu.

They are like moths to a fire, even if they are hit by an arrow, they have to place the things in their hands on a deep ravine, but obviously they are in vain, many people simply do not have the ability to take a step forward after being hit by an arrow, and the rain of arrows in the Great Song Dynasty is like a dark cloud that covers the sky and the earth, and like raindrops, the Liao people have nowhere to hide.

Di Qing stood not far from Zhao Zhen and commanded calmly, no, he could explain it to Zhao Zhen, after all, the emperor personally went to the front line, and he, the general, had to explain it to some extent, at least let the officials know Zhao Zhen's steps.

"Your Majesty, don't look at the things that these people carry in their hands, in fact, most of these things are not of much use, but the goals given by the generals to the soldiers, and the whole role of these front armies is actually to fill the pits, just like these deep trenches in Xijin Mansion are just prepared to consume the enemy's front army, in fact, the life and death of these people are insignificant."

After listening to Di Qing's explanation, Zhao Zhen's heart twitched fiercely: "Could it be that the Liao people don't feel sorry for the people under their rule at all?" ”

Di Qing smiled and said: "Of course these people are not distressed by the Liao Dynasty, they are just slave soldiers, sometimes some death row prisoners who have committed crimes, or mature women are really slaves and the like, just like the Jurchens released by His Majesty from the palace, if the man who gave birth to a Jurchen is caught, he will inevitably appear in the slave army." The lives of the Bohai people are even less valuable. ”

With Di Qing's words, the corpses of the Liao people soon filled the ravine, and the ditch-filling things they were originally holding in their hands were still like decorations, as if they were laughing at the inadequacy of these people.

"Won't these people resist?"

Di Qing sighed slightly when he heard Zhao Zhen's words: "At the beginning, there will be some people who don't want to be sacrificed, but as long as they resist, they will be slaughtered, and the generals of the Liao Dynasty will tell these people that once they put the things in their hands on the ravine and come back, they can get their own ......."

Zhao Zhen didn't need Di Qing to finish speaking, he knew that the Liao people had given these slave soldiers a blank check and a bright future, but this future was like a mirage and could not be obtained, how many slave troops could really return? Zhao Zhen basically didn't see how many slave soldiers returned.

Just when Zhao Zhen thought that the Liao people's death behavior was about to end, the Liao army's position sounded the horn again, and the same scene appeared as just now, but this time the Liao people's equipment was obviously much better, with some armor and shields as cover.

The slave army was a group of refugees, and they were much more equipped with more equipment, not only simple iron armor, but also huge wooden shields, and a lot of siege equipment behind them.

This is probably the normal offensive of the Liao people, right?

But Zhao Zhen's idea was quickly denied by Di Qing, and seeing the appearance of the official family, Di Qing spoke again: "Prepare the bed crossbow!" Load up the fire and shoot it! With Di Qing's order, the herald holding the flag on the side quickly shouted the banner, and the three-bow bed crossbow on the city wall quickly aimed at the target and shot a huge crossbow arrow with fire, saying that it was a crossbow arrow was no longer appropriate, it should be called a spear.

Once these crossbow arrows with flames hit the Liao people's siege equipment, they did not penetrate as before, but turned into fragments, and the fierce fire oil that was scattered was quickly ignited by the flames of the spear heads, forming a burst of fireball.

The so-called fierce fire oil is actually unrefined oil, this thing has a very high viscosity, as long as it is stained, it will be like a maggot on the tarsal bone, unless even the meat is cut off, otherwise it is waiting to be hurt to death.

This is already a bit of the prototype of the gasoline bomb in later generations, although the power is not as great as the gasoline bomb, but the killing effect is basically the same, with the continuous launch of the bed crossbow, there is a sea of fire on the battlefield, and the burning Liao ghosts cry wolf howl, and also let the Liao army array at the downwind smell a smell of meat......

It is quite important to destroy the enemy's siege equipment, Di Qing's keen sense of war made him discover the role of artillery, a magic weapon, in defending the city, and the Liao people knew that ordinary siege equipment was ineffective against Xijin Mansion, and began to use a new siege equipment, Lu Gongche......

This Lu bus was first invented by the Han people, the car starts several floors, the soldiers are hidden inside, the leather is covered outside, and the ox pulls or people pushes, it can be pushed to the city by surprise, because it is the same height as the city, it can directly climb over the city wall, and the enemy fights, and this is not a single army, but a composite type, what immortal bridge, long wooden ladder, lazy dragon claw and the like can make the soldiers in the car better combat.

What amazed Zhao Zhen even more was that the Liao people actually prepared a dust truck!

The role of the dust truck is very simple, when the own army climbs the castle tower with flying ladders, etc., the dust cart pours lime powder on the defenders above the castle tower, forcing the defenders to retreat and cannot prevent their troops from ascending the city.

This is a bit of a flashbang or shock bomb effect in the future!

Seeing that Zhao Zhen was interested in the dust car, Peng Qi on the side hurriedly explained: "Your Majesty not only has a dust car, but also a fan car!" There are several of them in our Shijin Prefecture, although they are small but can be used in the tunnels, when encountering the enemy in the tunnels, the sergeant can retreat to the back of the car and use the fan car to spray lime, dust, or smoke to repel the enemy. ”

Zhao Zhen asked rhetorically: "Then how to deal with the enemy's dust truck?" ”

Peng Qiyi was speechless, and he really couldn't think of a good way for a while, but Di Qing was calm, and when the dust truck approached, he ordered the herald to send flags, and thick bamboo tubes appeared, Zhao Zhen took advantage of the situation to see that Di Qing used ice water melted by the snow on the high part of the city wall, which was stored in peacetime and used as a fire extinguisher in wartime, this idea was really ingenious.

No matter how big the smoke and dust is, it is blind when it encounters water, and the dust truck is drenched as soon as it arrives in the city.

It seems to be a simple restraint, but in fact, it reveals the confrontation of the wisdom of the commanders of the two armies on the battlefield, Di Qing, as the party defending the city, is naturally a soldier to block the water and come to Tutun, which is the advantage of defense.

Maybe in the eyes of ordinary people, the battlefield is chaotic, but in the eyes of Di Qing, Zhao Zhen, and Peng Qi, this is not the case, the front is always the shield player, and then the knife catcher and various types of troops, and the last is always the crossbowman, even if the formation is scattered, it will not leave this formation.

In the era of cold weapons, the formation is sometimes the key to victory, and the Liao people must arrange the formation of the siege if they want to attack the city, and the Great Song Dynasty is an expert in the formation, not to mention, Di Qing alone is a master of using the army array.

The front army of the Liao people was commanded by Yelu Zongxin, which is already an open secret, and the general of the defenders of the Great Song Dynasty was Di Qing, the general of the face of Nie, which seemed to be a contest between the two generals, but in fact it was a contest between the two emperors Yelu Zongzhen and Zhao Zhen.
