It was a moon occultation knife that had been improved by Sun Hui.

Originally, the Song army's field armies mostly used hand knives. But Sun Hui knew that this kind of heavy broadsword similar to the Mo knife of the Tang Dynasty was the most lethal, and once it was lined up in a battle array, it was almost unmatched.

Soon, this Song army opened the way with a long knife, advancing like a wall, and the Jiaozhi army was shattered, and it was invincible for a while.

At the same time, the left flank of the Cochin Army lined up a line of skirmishers, who wore short coats made of coarse cloth, and each carried a large longbow on their backs.

Sun Hui knew that it was the unique weapon of the ancient Jiaozhi people - rattan bow.

These longbowmen tied one end of their rattan bows to the ground and mounted their arrows. The arrows fired by the longbow were more than 400 feet away, but still had enough lethality. And the people who use the rattan bow are all sharpshooters in the Cochin army.

The jungles of Indochina are prolific and tenacious, and the Cochin people use them to make rattan bows to hunt, and these sharpshooters are all excellent hunters who have been mixed in the jungle for many years, and are now recruited by Chen Guojun to form a separate army to fight.

The standard equipment of the Song army was one bow per person, one crossbow for three people, and it was also equipped with a crossbow, which was connected to the wheel and could shoot while traveling, which was enough to deal a devastating blow to the enemy in the era of cold weapons.

But this Song army of 3,000 men did not use bows and crossbows. Because more ferocious long-range weapons came from the right flank.

At the same time as this Song army appeared a lightly armed force. They are equipped with armor that is completely different from that of their allies. Their armor had no metal armor plates, not even leather, and the pale yellow armor was neither iron nor wood, making them extremely lightweight.

This kind of armor only existed in historical books in history, but Sun Hui restored it with the help of the "omniscient eye" - using the design concept of modern body armor, using paper, cotton wool and cloth as materials, and processing paper armor with a special method.

When he saw those soldiers wearing paper armor take out a small crossbow with a square arrow box that was less than one meter long, Dong Jinhong, whose heart had been hanging, knew that the Song army had won this peak battle between the best archers.

That's a repeater.

With the emergence of elite units of the Song Army, various units of the Jiaozhi Army also began to enter the battlefield. The Song army, with the long-handled moon covering knife as the main weapon, occupied the left flank, and the sergeants in Mingguang armor moved forward steadily, and the rows of moon covering knives were like a snow-bright knife wall, pressing towards the opposite Jiaozhi army. On the right flank, the Song army, which used repeaters, stood on the hill and held up the slender repeaters.

The crossbowmen of the Song army in the Chinese army used a crossbow, which had to be stepped on with their feet and relied on the strength of their waist and abdomen to pull them apart. The Divine Arm Bow has an ingenious force system, through a complex gear structure, the soldier can pull it apart with only the strength of the arm, but the power is more than three times that of an ordinary hand crossbow.

With a soft "bang", there was a slight vibration in the battlefield, which was the special sound of the silk bowstring of the repeater as it shook the air. There was a thick murderous intent in that flat voice, even if it was separated by hundreds of feet, Dong Jinhong still couldn't help but tremble in his heart.

A dense raindrop suddenly flew out of the array of the Tianji Camp, drawing a semicircular arc in the air, passing the apex and accelerating down, covering the longbowmen of the Cochin Army on the opposite side in an instant.

The arrows of the Song army's crossbow were extremely small, the total length was only a few inches, and only one hand was long. Such a small arrow will become the most terrifying nightmare of the Cochin Army in the years to come. At a distance of several hundred feet, no armor could withstand the fire of a repeater. Even the finest armor of the Cochins was easily pierced.

After just one volley, there was not a single standing cross-toe longbowman on the opposite side. The Song crossbowmen re-aimed, this time targeting the Cochin infantry 700 feet away, armed with shields and scimitars.

After witnessing the power of the Song army's bow and crossbow, the Jiaozhi army immediately closed its formation. The first row knelt on one knee and held their shields in front of them, while the second row stacked them on top of each other, and then stacked them in layers of fish scales, leaving no gaps.

The Song crossbowmen calmly aimed at the target, and with the commander's order, the arrows rained down on the Jiaozhi army with a deathly scream.

There were countless tiny black dots on the wooden shield painted with the pattern of the beast's face, and the entire strong array formed by the shield shook slightly, and then blood meandered out from under the shield, staining the earth red.

Seeing this scene, Sun Hui was also surprised.

Even a modern machine gun here is not as powerful as these thousands of crossbow salvos.

The Jiaozhi army fell in pieces under the rain of arrows from the Song army, and the corpses piled up, even separating the two sides of the war.

"With such a fight, the Vietnamese are dead." Xiao Tiantian said beside Sun Hui.

"It's hard to say now, there are too many Vietnamese, 200,000 people, and they won't die so easily." Sun Hui said, his eyes still fixed on the battlefield.

"There seem to be a few strange people over there." Ye Chuchu suddenly pointed to the position of the middle army of the Jiaozhi Army and said.

Sun Hui looked in the direction she was pointing, and saw a general in gold armor talking with his entourage for a moment, and then with a wave of his hand, dozens of cavalrymen in full golden armor around him immediately galloped out. They held huge spears in their hands, their faces completely covered by metal helmets, with only two rectangular holes revealing their eyes.

"The Vietnamese also have heavy cavalry? Impossible, right? Wang Linlin said in surprise.

"It's just a few dozen people, let's see what tricks they can play." Du Lili said.

The horses on which these cavalrymen rode were also good horses, and they were all covered with golden armor, and they quickly crossed the battlefield under the rain of arrows, passed through a junction of the Song army's formation, and rushed straight up the hill to the position of Gundam's handsome banner.

As the reserve team, the Song army commander and the guards stood up at the same time, raising their spears and spurring towards their war horses. But the ferocity of these cochin cavalry was outstanding, and they galloped through the jungle of spears with their superb horsemanship, like a quick knife cutting through the line of defense formed by the commander's tent.

Before the Gundam moved, Dong Jinhong had already swept down the hill like a swift wind, and the sword in her hand had turned into a long rainbow, splitting the spear of a cochin cavalryman into two sections, and then with a "ding" sound, the sword cut through his golden armor and cut him in two.

"This kid has good skills." Wang Linlin exclaimed, "It seems that there are still a few capable people under this old man. ”

"It's not how powerful his martial arts are, it's the sword." Ye Chuchu frowned, "His sword is very unusual. ”

As Ye Chuchu said, such a result was obviously beyond Dong Jinhong's expectations, the more she fought, the more courageous she became, and the fierce sword light flew around, forcing the two golden-armored cavalrymen who came side by side to retreat step by step. Suddenly, a rider dressed in black appeared in the battlefield like a ghost, pulled out a strange scimitar from his armpit, first killed a Song army guard at hand, and then slashed at Dong Jinhong's sword.
