The Yan army advanced quickly according to Zhu Di's instructions, and wanted to attack the capital as quickly as possible, but what they seized was the emptiness of the capital's defense, Geng Bingwen's army was trapped in Zhending Mansion and could not return to help, so at this time, the defense force of the Ming capital could not be compared with the menacing Yan army.

The sound of horses' hooves, the 20,000 elites of King Yan quickly marched forward, coming out of Xuzhou City, almost encountering any obstacles, suddenly, there was a loud noise, and the mountains shook suddenly, and in an instant, the entire ground exploded.

The front army was in a mess, and the huge sound kept coming out, and even the war horse under the crotch was also blown to a bloody blur, "Retreat." The leader hurriedly turned the horse's head, and with a bang, the front hooves of the war horse seemed to step on something, and the sand in front of him flew up a few feet high, and with the huge impact, the whole person fell off the horse.

"General."

As the man fell off his horse, more than a dozen guards approached quickly, which was deadly, and the entire ground was already covered with fire and thunder, and it was extremely well camouflaged, and as several people approached, the sound of explosions was heard around the Yan army general again.

"Report to the prince immediately."

The figure stood up, suddenly spat out a large amount of blood from his mouth, and then fell to the ground at once, although he had armor on his body, his body had been damaged by the huge impact force of those explosions.

"Withdraw."

The former army retreated in embarrassment, did not see the shadow of the opponent at all, lost a main general, and also suffered nearly 5,000 casualties, Zhu Di sat in the carriage, don't look at Zhu Di is a general, such a long time of riding a horse is still unbearable, so he simply got the carriage.

"Lord Wang, a large number of fire and thunder were found ahead, and General Tiger was killed, with nearly five thousand dead and wounded."

"Fire Thunder!"

Zhu Di is no stranger to the fire thunder, this kind of firearm buried in the ground to kill the opponent has appeared in the Ming Dynasty, just one point, the fire thunder must be buried in advance, and then wait for your opponent to step on it, which requires a very high judgment of the situation, therefore, the Ming Dynasty made more convenient firearms and artillery, this kind of fire and thunder is rarely used.

"Wait for me."

Zhu Di got off the carriage, someone brought the war horse, and then approached the place where the accident occurred in the front army under the escort of the Chinese army, the smoke had not yet cleared, the ground was full of stumps and broken arms, and a large number of deep pits appeared in the entire front space.

"There are so many fire and thunder!"

Zhu Di couldn't believe his eyes, it was better to spend so much energy to make fire and thunder than to convert it into firearms, although the technology of the Ming Dynasty was improved compared to the Yuan Dynasty, after all, the number of craftsmen who could produce firearms was limited, and the production of firearms was very dangerous, once it was not operated properly, not only the firearms would be destroyed, but the craftsmen would also be injured.

"Lord Wang, next, how to march?"

The former army general was killed, someone carried the corpse over, the blood on the body had dried up, such a fierce general actually died like this, Zhu Di waved his hand, "Find a place to bury it." ”

Dao Yan, Ma Sanbao and others all came from behind, the old monk frowned deeply, and urged the horse to come closer, "Lord Wang, last night the old monk watched the sky at night, the celestial phenomena changed, and the dragon protection star suddenly shone. ”

"Dragon Guardian!" Zhu Di frowned when he heard this, Dao Yan knew the method of calculation, predicted the future by observing the celestial phenomena, and when he raised the army, Dao Yan said that the imperial star was weak, and Zhu Di's natal star had the appearance of seizing the master, but he didn't expect to suddenly make a dragon protection star.

Dao Yan nodded, "The celestial phenomena are ever-changing, and they are definitely beyond the control of you and me mortals, but the prince can rest assured that the prince's natal star has not been affected." ”

"Inevitably, time goes by, and there are many changes, so be careful and use a spear to find the way."

This is Daming's method of dealing with fire and thunder, that is, to use that kind of long spear to stab forward, once it touches the fire thunder, the fire thunder will explode, because of the length of the spear, the damage suffered by the person holding the spear will also be weakened countless times.

As soon as the order was given, hundreds of soldiers armed with spears immediately came out of the camp, lined up, and then walked with spears in hand to the place where the front army had just been attacked.

Don't look at the spear in your hand, you are still scared at this time, especially when you see the stumps and broken arms all over the ground, the speed of travel is getting slower and slower, the spear in your hand is put down, and you keep stabbing forward.

One of them seemed to have stabbed something, and with the force of his arm, he quickly stepped back and stepped on his left foot, which felt very strange, the trigger principle of fire and thunder has been similar to that of modern firearms, leaving a space on it that can be pressed, and once someone steps on it, it will trigger the gunpowder inside.

With a bang, several people around that person were blown away in an instant, and the people around them suddenly became more nervous, the fire and thunder buried by Lin Feng was very ingenious, there was almost no regularity, it was completely holding the fire thunder, and then burying it from the front to the back in order, not only the ground, but also the fire and thunder under the stones.

A loud bang came out, King Yan's first attempt failed, and the remaining dozens of people quickly retreated, Ma Sanbao frowned, as the chief manager of King Yan's Mansion, he was familiar with various classics, and he also knew firearms very well.

"Lord Wang, this shouldn't be an ordinary fire thunder, it should be transformed." After Ma Sanbao finished speaking, Zhu Di nodded, "Sanbao, is there a solution?" ”

Ma Sanbao thought for a moment, "Lord Wang, there is a war horse in the army that cannot fight, and he can use the speed of the war horse to rush in, and he should be able to destroy enough fire mines." ”

"Okay, let's do it according to the meaning of the general manager of the three guarantees."

The neighing of the war horses was bursting, and the horses were driven out with spears, probably feeling the breath of death on the battlefield, so they became extremely agitated.

Most of these war horses are wounded, close to hundreds, and there are cavalry guards with spears on both sides, as the command flag is lowered, the cavalry behind them quickly drives away, there is no way, those injured war horses can only rush forward desperately.

This trick really works, because the speed of the war horse's impact is very fast, even if you step on the fire thunder, it is very likely to rush out at the moment of the explosion of the fire thunder, so that you can continue to destroy the fire thunder in front.

The explosion shook the sky, and at this time, Lin Feng stood on a high place and could see clearly, looking at the army of King Yan in the distance, thinking about how to use the terrain behind him to eliminate these people.

With the last two war horses falling, this time it is dozens of zhang away from the last time, the front is the woods, the back is the mountain, you can take Lingbi directly from here, although Lingbi City is dangerous, but the scale is too small, there is no way to deploy troops on a large scale, so only Fengyang Mansion can threaten the Yan army to attack the capital.

Zhu Di's plan was to raise troops to invade the capital from two routes, so whether Fengyang could be occupied and the passage from Beiping to the capital was extremely important to the whole situation.

"Kill."

With the fall of the war horse team, Zhu Di believed that the number of fire and thunder in front should not be much, the front army killed again, this time the number of explosions was significantly reduced, Zhu Di was happy, although he caused himself a certain amount of trouble, it was just a small skill of carving insects, and in the end, it was the primitive infantry cavalry that won on the battlefield.

The front army of the Yan army passed through the woods smoothly, and the scale of the woods was not large, which was why Lin Feng did not ambush the soldiers inside, once discovered by the other party, the area behind was too open, and there was no way to avoid the pursuit of the opponent's cavalry.

There are three passages in front, one is a canyon, one is a big road, and the other is a winding path, and the 100,000 army of King Yan must want to pass from here as soon as possible, so take three ways to divide the troops.

One of the most dangerous is the middle canyon road, the least number of troops passing through, and the other party is most likely to ambush the troops, so Zhu Di sent Ma Sanbao, and then led 20,000 elites.

The brigade of men and horses marched from the main road, and 20,000 soldiers and horses went up along the mountain, ready to climb directly from the ridge, at this time, Lin Feng was in the canyon, and the Jinyi guard on the side was holding several different colors of the order flag in his hand.

The style of play on the battlefield is sometimes rough and simple, watching the flag during the day and listening to the drums at night, so those who are generals must understand the meaning of the flag order and the different ways of playing the drums.

"My lord, the Yan King's chaotic army has divided its troops in three ways, and one of them has approached the canyon."

"How many?"

"One or two thousand people."

"Let them go first."

"Yes."

Lin Feng is not in a hurry, King Yan is in a hurry to march, worried that the war will drag on for too long and the supplies will not be able to keep up in the later stage, Lin Feng does not need to worry about this at all, even if it is the strength of the whole country, it will ensure the soldiers who fought in front.

Ma Sanbao walked in front with the cavalry, the mountain here is indeed steep, fortunately the width of the canyon is enough, and the length of the canyon is not as long as expected, so once you find something wrong, immediately increase the speed of the march and pass quickly.

After walking out for two hours, there was no shouting in the canyon, King Yan put his mind at ease and urged the front army to speed up, almost at the same time, the soldiers standing on the cliff saw the command flag raised in the distance, and almost at the same time, the boulders that were docked on the edge quickly rolled down.

Boom, the momentum is amazing, Ma Sanbao looked up sideways, startled, four boulders fell from a height of dozens of zhang in front, each weighing thousands of catties, and then fell from that height, even if you are an iron body, you will be smashed flat.

At this time, there are two roads in front of Ma Sanbao, rushing over quickly, such a distance, using the speed of the war horse should be able to do, just a little, even if he rushes over with the people in front, the people behind can't catch up, once the road is blocked, it will be even more troublesome at that time.

"Retreat."

Ma Sanbao decisively chose to retreat, the other party had already prepared, so what he was most afraid of was that the back was the same as the front, and there were boulders falling, so it was equivalent to being trapped in it directly.

Boom, Ma Sanbao's worries still happened, more than a dozen boulders fell from above, the entire camp was cut into several parts in an instant, the boulders blocked the way, the cavalry had no way to pass, Ma Sanbao jumped off the horse and jumped quickly onto the stone, "Don't panic, march from both sides, quickly." ”

Although there were big boulders blocking the road, the infantry could still climb over from the mountains on both sides, so the whole situation was not as bad as imagined, until the figure of Jinyi Wei appeared from above, holding the black thing in his hand, and then pulled it violently and threw it directly into the Yan army trapped inside.

Boom, Lin Feng's firearms battalion once again showed its might, with a loud bang blossoming in the middle of the Yan army's camp, the Yan army's casualties were extremely heavy, not only the deaths and injuries of firearms, but also the soldiers trampling on each other, and the steep mountain walls on both sides were not so easy to climb.

The most important thing is that, in addition to those Southern troops with strange things in their hands, a large number of Jinyi guards with firearms poured out from below, and the pitch-black muzzles were aimed at the chaotic troops who had just climbed up.

Almost at the same time, above the ridge, the wide road, as the Ling Qi was raised, the elite of the Jinyi Guards who were ambushed inside came out one after another.
