Yang Hongru's fantastic idea did not get the support of the deputy general, but whether you support it or not is your business, and whether I create it or not is my business.

After years of development, Yang Hongru discovered that his low-end version of Mediation also has the function of unconditional chemical reactions. The simplest example is that Yang Hongru can directly decompose water into oxygen and hydrogen.

Power on? No need!

Therefore, he can also decompose pyrite into pure iron and pure sulfur just by rubbing it with his hands, and then unconditionally react pure sulfur with water (h2o) to produce concentrated sulfuric acid (h2so4).

These reactions do not cost him too much mana, and it takes the most mana to create something out of nothing.

After defusing these concentrated sulfuric acid shells, Yang Hongru ordered the soldiers to carry them carefully. If this thing was spilled, it would be life-threatening. Although he could save people, the concentrated sulfuric acid is highly corrosive, and the water splashed on the body will absorb and carbonize.

The reaction process always hurts!

It's not a problem to wait like this all the time. The risk of exposure will gradually increase as they camp. The soldiers are getting more and more anxious, and at the same time the most dangerous thing happens - two scouts do not return to the team!

This means that these scouts may have encountered a crisis and are lucky to fall into a trap. If they are caught by the Rouran army, the consequences will be unimaginable.

Yang Hongru was cautious and asked his men to set up the ten-door tiger squatting cannon facing the southwest - the lost scout was going to the southwest for reconnaissance, and the key defense direction was that way.

If Rouran didn't sneak around to attack Juhua, there would be nothing wrong with the cannon pointing in this direction.

Lieutenant General Yang Hongru and the others had always viewed the strange-looking iron guy they had been dragging with suspicion. Although he had also heard that this thing helped them defeat many fortresses on the march, he really did not believe that this thing could kill seven or eight hundred people.

One step away.

Now the only thing the lieutenant hopes for is that reinforcements arrive earlier than the enemy, otherwise they can only retreat in despair.

The speed of the Rouran cavalry is no worse than theirs. Unless some soldiers are left behind, they will never escape from their grasp.

Fortunately, they dug some anti-cavalry trenches when they set up a temporary camp. The cavalry themselves certainly knew how to deal with the cavalry. The Northern Wei cavalry was also very good at digging trenches, and the layout of the horizontal and vertical trenches was quite scientific.

Horizontal trenches can reduce the speed of cavalry charges, vertical trenches can cause horses to stumble, and well-arranged horizontal and vertical trenches can effectively prevent enemy sneak attacks.

However, something unexpected happened, and Murphy's Theorem popped up from time to time to make its presence felt. The deputy general's great expectations were in vain - the Rouran Cavalry came first.

It is definitely impossible to fight, and only part of the force can be left behind to block the attack and cover the retreat of the large forces.

The most suitable people to stay here are Yang Hongru and his group. It's not that the lieutenant is targeting him, but that they have the best weapons and equipment and have the greatest chance of survival.

It is impossible for Rouran to launch a charge with two thousand cavalry, and find that their Rouran troops are just the vanguard. If they successfully entangle this detachment, the follow-up troops will arrive later and eat up this cavalry detachment of 500 people.

If Yang Hongru and others stop these advance troops, many people in the whole team can escape. If they cannot stop them... everyone will die together.

The deputy general looked at Yang Hongru, who nodded firmly: "You retreat first, I will take the lead!"

"Take care! If you come back alive, I'll treat you to a drink!" The deputy general did not hesitate and prepared to retreat with the remaining four light cavalry.

Seeing the Rouran advance team getting closer and closer, only one kilometer away from them, he immediately ordered: "Fire!"

The gunner immediately lit the fire, the match rope burned, and five seconds later the gun was successfully fired.

The iron can was pushed up to the sky by the artillery. After the iron can was in the sky, it rotated in various ways, throwing out the concentrated sulfuric acid contained in it and falling from the sky like light rain.

The iron can fell from the sky first. The iron can, which was endowed with powerful kinetic energy, was as powerful as a cannonball. If it hit the charging Rouran cavalry, it would kill him.

After the iron cans fell to the ground, the concentrated sulfuric acid falling from the sky was the main course of this wave of bombardment. Some of the unprotected Rouran cavalry simply fought bare-chested. As long as the concentrated sulfuric acid stuck to their bodies, their skin and flesh would be torn apart immediately.

Not only the people, but the war horses were in unbearable pain after being stained with concentrated sulfuric acid. They immediately spread their hooves and ran around. The good charging formation was immediately disrupted to pieces.

Rouran's advance cavalry consisted of nearly 500 people. Before they could get close to each other, at least 100 of them were injured and fell off their horses when shooting arrows. Some of them were even trampled to death by the crazed horses.

Being trampled to death by a war horse is a very common death method in ancient battlefields. The chance of survival after a cavalryman falls off his horse is not high, especially during a collective charge. Falling off his horse is almost the same concept as hanging the ball.

"Change the shotguns!" Yang Hongru continued to give the order. The enemy formation was already scattered, so it was most appropriate to blast shotguns outside at this time.

After the shotgun shells wrapped in oil paper were stuffed into the muzzle, the cannon fired again, and a salvo took away dozens of lives.

Immediately afterwards, Yang Hongru issued the last order: "Withdraw!"

The joy of running away after pretending to be cool is something Rouran can't imagine. If I can bully you from a distance, why would I fight you at close range? What did Lao Li say back then?

If labor and management are rich, each of them will fire a machine gun... Now Yang Hongru and Rou Ran are fighting a war of wealth. We are both firing, and you can only be bombed like rabbits.

Although the heavy cavalry retreats slowly, we can endure the beating!

Taking advantage of the enemy's dispersion, Yang Hongru asked everyone to retreat with small cannons. Occasionally, some scattered Rourans caught up and were shot back by Hua Mulan.

Hua Mulan is a girl with average cavalry combat ability, but super strong cavalry and archery ability. Her destiny unit should be cavalry archer, which comes from her father's education. Her father is an old hunter and has always been a ranger archer in the army.

However, because Yang Hongru gave her too much, she was forced to change her job to a heavy cavalry. How handsome the heavy cavalry is! How awesome the heavy cavalry is!

Not only was Hua Mulan accurate, but Yang Hongru, an old silver coin, simply rode a panda upside down and fought back with a crossbow on the broad back of the panda.

The reason why it is difficult to use a crossbow on horseback is that it is difficult to string it up, but who is Yang Hongru? Ordinary soldiers can push up the crossbow string with their feet, but Yang Hongru can do it with his arms.

So Yang Hongru can shoot with a crossbow on horseback - the distance of the crossbow is similar to that of a gun, and its ballistic trajectory is more stable, making it easier to aim.

Yang Hongru's crossbow was specially made for himself, and it was so powerful that it could penetrate a steel plate a hundred meters away--at close range, several cavalrymen could be shot with one crossbow!

Rouran was also fleshy, so it would be useless to pursue him after Yang Hongru and the others beat him to this level. On the contrary, if Yang Hongru could occupy a favorable terrain and launch a countercharge, Rouran who was chasing behind him would die here.

When pursuing heavy cavalry, one must be mentally prepared to be counterattacked at any time. After being cheated and repaired by Yang Hongru several times, Rouran's advance team only had more than 200 people left. If they continued to pursue, there was a real danger of the entire army being annihilated.

Two hundred light cavalry want to kill a hundred heavy cavalry... Only in dreams can such a beautiful scene appear.

Reality?

Impossible!
