A black-feathered and iron-bone Mitsubishi arrow weighed three or two cents, a standard that Na Himatsu himself had set after many adjustments, twice as heavy as the arrow used in the longbow of the light cavalry, and could pierce light armor and kill in one blow within 300 steps.

Zhao Tianyou reacted at the moment when the arrow left the string, feeling a slight tingling in his skin, as if he was being targeted with a gun, and then ordered the thunderbolt cannon to fire with a wave of his hand, and at the same time his body took a step back.

The sharp arrow cluster pierced the clothes on the shoulder, and with a "ding" sound, it was nailed to the wall far behind him, and the feathers at the end of the arrow buzzed lightly under the light, and it trembled for a while before it completely stopped, which shows how amazing the strength and accuracy of this arrow are.

Eight groups of thunderbolts with scarlet dots flew towards the ranks outside the city with a low whistling sound in the night, and the burning fuse drew a red trajectory, indicating their extraordinaryness to the blackened cavalry outside the city.

"The back team becomes the front team, two hundred steps back!" The shouts sounded one after another, and before the thunderbolt cannon hit the ground and exploded, the Yuan soldiers had already begun to adjust their formation, preparing to retreat away from the crossbow beds on the city.

This is not Panasonic's order that day, this is the conditioned reflex of free stimulation after the cavalry of the Yuan army discovered the lethal weapons at the head of the city, which is generally issued by the leader of the hundred captains or above, except for the order that the lord will not retreat.

Under this flexible tactical structure, the combat effectiveness of the individual units of the Yuan soldiers is very strong, and no matter how big the strategic goal remains the same, it can be very flexible to adapt to the ever-changing situation on the battlefield. In this regard, several generations more advanced than the rigid structure of the Song army, civilian officials were wary of many irrational systems formulated under the condition that the army was too powerful to control, which affected the cohesion and centripetal force of the army.

It is a pity that the Yuan soldiers underestimated the thunderbolt cannon fired at the head of the city, not only the power to shoot down three or five horses, but also the twenty-four huge crossbow arrows with thigh-thick thickness, which fell into the center of the procession, causing a short period of people to turn on their backs.

The great inertia was gone, and the bolts fell to the ground, and the unfortunate ones hit by the bolts were seriously injured or killed, and the blood they shed did not stop the fuse from burning to the sneer, and the gleaming red light disappeared before pausing for a moment.

"Boom, boom, boom!"

"Boom, boom, boom!"

In a series of loud explosions, patches of horses fell and struggled, and countless riders were lifted off their horses by the flying projectiles, and trampled into a mass of flesh by the hooves of the horses that followed. The horse team, which had retreated in an orderly manner, was disturbed and turned into headless flies, and countless horses were injured and fell under the collision with each other, and the cavalry on their backs were crushed and trampled to death.

But this was not the end, before the first wave of thunderbolts did not explode, a dozen strong men did their best to hang the tight machine springs on the crossbow bed, and three huge crossbow arrows side by side, with long fuses attached to them.

"Put!"

This time the launch was carried out separately, and the squad leader was responsible for adjusting the angle and trying to shoot the thunderbolt into the densest part of the enemy, as long as it was aimed, it was ignited and fired immediately, and the third wave was fired as much as possible before the enemy escaped from range.

Zhao Tianyou's shoulder was cut by a sharp arrow cluster with a bloody mark, and he rushed to the head of the city again as soon as possible, lying between the arrow stacks and scanning the team under the city, trying to find the person who shot the arrow.

Nari Song had already turned his horse's head and retreated to the rear under the cover of the pro-guards, but they did not know that the denser the group, the more it would attract the attention of the gunners at the head of the city. Fortunately, the gunners at the head of the city carried out the tactics of first near and then far, and the calibration of the thunderbolt cannon had already aimed at the enemy at the farthest end of the firing range of 700 paces.

Na Risong gritted his teeth, crossed the wounded soldiers who were still struggling on the ground, turned his head and glanced at the city viciously, he did not know the result of his arrow, and felt that the man could not be avoided. A few hundred paces away, he saw a person in the middle of the arrow stack, looking at him intently, as if the eyes of the two people met in the air, and sparks instantly sparked.

Zhao Tianyou saw that Risong's fierce eyes, and had already concluded that it was the person who shot his arrow, and at the moment when his eyes intertwined, he instinctively made a throat-cutting action at him. That Risong immediately understood that this was a challenge, and the other party was also a master with a bow and arrow, an agreement between the strong and the master, a battle situation in which life was a bet.

Narisong suddenly became very excited, and the cavalry with countless casualties also felt insignificant, and he had an almost obsessive love for the art of bowing and arrows, and he had not found a decent opponent for many years of fighting. The man at the head of the city is definitely a master of archery, and his extraordinary eyesight is the basis of archery, if his eyes are not sharp, how to capture the trajectory of the target in high-speed movement.

With the sharpness in that person's eyes, he noticed his eyes in the army like an invisible arrow, and when he thought about it, he was very excited, and he was very eager to experience the other party's archery attainments.

The third wave of thunderbolts bit the tail of the cavalry team and exploded, and the effect was still good, in addition to the horses and cavalry that were blown up at that time, it also completely shocked the long-trained Mongolian war horses. This retreat was not a distance of a few hundred steps, and by the time Risong reorganized the team, it was already early in the morning, in the farmland three miles away from the west city gate of Guangzhou.

"Report to the general, the number of people in each brigade has been counted, and the loss of men and horses is about 1,000, and there are wounded soldiers who have lost horses to meet and reconcile, and the final number will change!"

The order was given, and the whole team marched forward and set up camp one mile away from the west gate of Guangzhou. Send people out to rescue the wounded, collect and bury the corpses of the dead in the city. "That day Song suffered the first defeat, but he still did not hurt a single soldier of the opponent, and paid the price of more than a thousand cavalry, and the result was that he hid in the ranks and shot an arrow at the head of the city.

Zhao Tianyou had already gone back to sleep, and with the efforts of this day and midnight, he successfully captured Li Dayong, cracked the crisis of the West City Gate, and severely damaged the Narisong troops who followed. This was a beautiful start, and it boosted the morale of the Song army a lot in general, especially the defenders of the West City Gate.

Most of these defenders were defeated and retreated from the northern cities, and they were unwilling to surrender to the Yuan and go south to Guangzhou City, but they all had a psychological shadow for the Yuan soldiers, especially the soldiers who had fought the battle to defend the city.

The Yuan soldiers set up camp very close to the outside of the city, bullying you for not having long-range weapons, and knowing that you dare not go out of the city to fight, the arrogance is incomparable. However, their method of attacking the city was also very effective, and after crossing the city gate, the archers threw the defenders on the earthen city, taking advantage of the geographical advantage, and could kill and intimidate the defenders in large numbers.

This time, before the official battle, it was bitten hard by the defenders of Guangzhou City, and when the thunderbolt cannon exploded in the ranks of the Yuan soldiers, the jaws of the soldiers of the city guards fell to the ground, and they were amazed at this powerful weapon to defend the city.

At dawn on the second day, the Yuan soldiers were cleaning the battlefield outside the city, and at the same time sent someone to shoot a letter at the city.
