Kang looked at the skyrocketing fire, and his mind suddenly went into chaos. The whole of Uri turned into a sea of fire, and everywhere he could see was dancing flames, and even the places that could not be seen from a distance were red to the sky, but Long Kang couldn't tell the difference, he only knew that his surroundings had turned red.

Long Kang couldn't figure out how the Beifu Army accomplished this feat while being shocked. There is no doubt that the fire in Wuyi City was caused by a "spark" that fell through the sky. Long Kang also saw with his own eyes that dozens of fireballs with long tails smashed not far away, almost without sound, and the fireballs turned into countless sparks and flew in all directions. The sparks splashed in unimaginable light wherever they went, wood or earth, and quickly joined into a sea of fire.

Long Kang saw with his own eyes that the mansions of the two ministers turned into a sea of flames, plus hundreds of orange figures struggling and screaming in the sea of fire, and couldn't help but fight a cold war. Around him, thousands of soldiers who were ordered to "defend" the northern city wall of Wuyi also shivered involuntarily. Death is already a terrible thing, and such a tragic death makes all people feel afraid, a fear from the bottom of their hearts.

This kind of tactic is beyond the imagination of all Yanqi people, and it is almost comparable to the divine power of the Heavenly Dispatch. Long Kang wanted to try to figure out how the Beifu Army did this? The battle has reached this point, it doesn't matter whether the Beifu army rushes in or not, in this purgatory-like Wuyi City, it is a very difficult thing to survive, and it is even more difficult to recover from this spiritual blow.

Long Kang shouldn't have imagined that the key to all this was on the hill not far outside the city.

As the artillery commander of the Battle of Wuyi City, Yu Gui's task was to observe Wuyi City at all times with a group of artillery staff officers on the mountain bag. Use simple geometric observation tools to measure areas that are not on fire, or where the fire is beginning to wane, and then provide commands and data to distant artillery units to let the whistling fire oil shells fall where they belong. Because Zeng Hua gave Yu the task of returning to the land, all the places in Wuyi City must be burned all the time in the dark night.

Unlike Long Kang, Yu Gui knows very well how all this is made. As the first batch of "artillery commanders" of the Beifu Army, he knew very well the power of the counterweight stone artillery of the Beifu Army. These weapons, which use gravity, gears, bearings, and other devices as much as possible, have been mechanized to the extreme. In addition to providing the initial power for the stone cannon, the rest of the manpower is left to the machinery to operate. In addition to greatly reducing manpower, this goes down. It also allows the firing of stone cannons to be mathematically quantified as much as possible. The ratio of sulfur and fuel oil to fuel oil was strictly prepared by the Beifu Ordnance Factory.

The liquid obtained by simple distillation of "crude oil" is that even the "omniscient" Zeng Hua could not figure out whether it was kerosene or diesel. However, these liquids are a good tool for setting fires. Add some paraffin, sulfur and other "combustion, thickeners". Then put it in a clay pot with a strict control of shape and weight, and finally ignite it and launch it, and when it falls, it is a large piece. And this kind of fire is extinguished with water according to common sense, except with sand and soil. However, it is unfortunate that the Beifu Army did not pass on the relevant firefighting knowledge to the whole of Yanqi State.

After Zeng Hua introduced parabola and other mathematical knowledge based on high school mathematics and advanced mathematics, ballistics was included in the Beifu military discipline as the basic knowledge of artillery, and the artillery department of Bacheng Military Academy and the arithmetic department of Chang'an University joined forces. It has made this emerging discipline more perfect, but today is the first actual battle.

Today, Yu Gui and this group of artillery staff officers have a profound understanding of what Zeng Hua once called "mechanical power" and "sea of fire tactics." Manpower is always limited, and it is also unpredictable, and the machine is just the opposite, not only "infinitely powerful", but also can be controlled by the mediation of "some organs", and if you add some arithmetic factors such as wind speed, you can roughly calculate the landing point of this stone cannon.

Yu Gui and these artillery staff officers still remember that when they saw the general with a group of "Chang'an University Hall" after "pinching their fingers" through an abacus and slide rule. It was actually possible to let ten stone cannons hit the stone projectile into a big ***. Although this *** is a bit big. But Yu Gui still understood that it was already a great knowledge to be able to point such a powerful stone cannon to where to fight. Science is a thing that follows the development of history. Finally, the first test of war and military affairs, although the time was much earlier. But the power it brought shocked everyone who saw it, and they remembered the word deeply.

Yu Gui had now overcome the shock of the 160 stone cannons covering the fire at the beginning, and was a little intoxicated by the tremendous power. Looking at Yu Gui, who stood on the mountain bag and turned Wuyi City into a sea of fire, even the former enemy commander-in-chief, Cao Yan, couldn't help but feel a little jealous, not to mention the rest of the Shanglin Six Tigers.

They were given the order to surround the city of Wuyi with their soldiers and horses, and while they were on guard, they took turns resting, waiting for orders to attack the walls they were responsible for. Looking at the fire of Wuyi City, which was already reflecting the entire night sky in front of them, everyone knew in their hearts that the attacks of their infantry troops were at most some tail sweeping work. If the Yan army can still maintain its combat effectiveness in this sea of fire, everyone doesn't have to fight, just roll up the covers and go back to their respective homes as soon as possible.

Long Kang didn't have the pride and sense of accomplishment that Yu Gui had, and his only thought now was that Wuyi City would definitely not be able to be saved. Long Kang stood on the city tower and watched for a while, and already understood the way the Beifu army set fire. First of all, the southern city, including the southern city wall, was all caught in flames, then the eastern city and the western city, and now it has reached the northern city, and according to this law, the fire should soon fall on the northern city wall.

The Beifu army should have used some method to divide the entire Wuyi City into many small areas, and at the same time, all the fire and oil bombs were poured into one area, so after a burst of artillery fire, no matter whether the target was high or not, this area was definitely a sea of fire. After igniting one area, it was immediately moved to another area next to it, so standing from a distance, Long Kang felt that the entire Wuyi City was like a neatly stacked haystack.

One was set on fire. Then the fires quickly joined together. The sound of the Beifu army is synonymous with looting and arson, and now it seems that the regular army is the regular army, and the arson technology is not many layers higher than that of the Qiang cavalry.

Long Kang walked down the city tower with his own personal army without saying a word, and as soon as he arrived at the foot of the city, hundreds of sparks had already flown over, and soon the north city wall that Long Kang was in charge of turned into a fire dragon, and thousands of defenders who were watching the excitement in amazement immediately fell into a sea of fire.

Listen to the heart-rending screams on the city walls. Long Kang no longer had any expression. His round eyes turned red in the firelight. Junxiu's face is distorted a little. The hideous face made the captain of the pro-soldier next to him feel weak for a while.

"Let's go!" Long Kang finally spoke.

"Prince, where are we going?" The captain asked boldly.

"Go to the palace, and I will take the queen mother and my sisters out." Long Kang gritted his teeth and said.

"Prince, the palace is now in flames." The captain said cautiously. Indeed, as a key target, the Yanqi Palace has long been on fire, and the road leading there is already soaked in fire. Who rushed past.

Long Kang didn't say anything anymore, just turned his head and stared at the captain of the soldiers fiercely, almost eating him alive, so frightened that the captain's legs trembled.

Long Kang did not pull out a steel knife and cut off his head in a fit of rage, as the captain of the pro-soldiers imagined. The prince, who had just sworn to hold on to Wuyi City and kill a few more Beifu thieves, suddenly became so weak that he stumbled back two steps as he looked at the fire in his eyes. The last butt sits on the ground. Howling and crying.

Listening to Long Kang's crying like a wolf howling in the crackling fire, all the pro-soldiers were silent. In the merciless war, whether it is the royal nobles or the common people. They are all flesh and blood, and their lives are insignificant in the face of the powerful war machine of the Beifu Army.

Later, Yu Gui's task was to replenish a fire oil bomb in a corner of Wuyi City, so that the fire lasted all night. In the endless night wind, the raging fire finally turned an eerie purple, and the screams of Wuyi City became weaker and weaker, until only the howling wind and fire echoed, which spread far away in the endless wilderness.

When the morning sun rose, Wuyi City had become silent in the black smoke, and this deathly silence made the Beifu army who had already lined up feel a sense of unprovoked emptiness.

Cao Yan looked at the tens of thousands of Beifu soldiers who were shining with white light under the morning sun, sighed, turned his head and whispered to the heralds: "Order all the armies to immediately besiege Wuyi City, move quickly!" By the time the sun comes up, it's too hot. ”

Speaking of this, Cao Yan couldn't help but glance at the Wuyi city wall that had turned black, and muttered, "It's too hot!" ”

The resistance of the Beifu sergeants was almost negligible. When they rammed the mangled gate, there were only a few hundred black-faced Yanqi sergeants gritting their teeth and shooting arrows, throwing spears and even throwing stones.

In the neat sound of slamming on the door, only a few sounds of arrows and spears colliding with the white iron armor on the Beifu sergeant could only be heard sporadically. In a few clicks, the gate of Wuyi City was knocked open, and the Beifu army drove into Wuyi City neatly, advancing towards their destination according to their respective tasks.

The Wuyi City that appeared in front of the Beifu sergeant could only be described as ruins, and the few survivors wandered there, not knowing whether they were looking for their relatives or their own souls. They didn't react at all to the surging Beifu sergeant, at most they just raised their eyes, glanced at them with a dead gaze, and then continued to focus on their feet or a hollow direction.

The final results came out, the city of Wuyi was razed to the ground, and less than 10,000 of the 50,000 soldiers and civilians remained. Long An closed the palace door in the fire, and the fourteen members of the family and hundreds of people in the palace were all reduced to ashes. Long Kang became insane in front of the ruined and broken palace, and when he was finally escorted to Cao Yan, he was already dancing and claiming to be the Five Heavens Divine Dragon.

After the count, Zeng Hua ordered the dead to be buried on the spot, all the ruins of the houses were razed, and all the living in Wuyi City were moved to Yuli City, leaving Wuyi City, which had become a large tomb.

In the end, Zeng Hua invited 4,000 monks who were hiding in several large temples such as Foguang Temple outside the city to overspend the martyrdom of Wuyi City.

In the midst of the chanting of Buddhist scriptures, the great monk Hui was brought to Zeng Hua.

"The general means that he wants the poor monk to bring this letter to His Majesty King Qiuzi." Megumi, who had been scared, finally breathed a sigh of relief, and it turned out that she was just calling herself a messenger.

"Yes, the great monk is highly respected, please bring the letter of General Ben to King Qiuzi. I don't want any more fighting. Zeng Hua's tone was very calm and sincere.

Listening to this, and then looking at Zeng Hua with a sven face, Hui couldn't believe that the fire last night was set by the general of Beifu.

"General, why do you want to overlive the revenant, are you afraid?" Megumi somehow plucked up the courage to ask something he shouldn't have asked, perhaps it was the humming sound of Buddhist scriptures that gave him great support and courage.

"Scared?" Hearing this, Zeng Hua suddenly turned his head, and his sharp gaze was like a knife towards Hui, so that this high monk who was originally like a deep well couldn't help but feel a little fluctuating.

After a while, Zeng Hua's gaze finally softened, he shook his head and said, "I'm afraid that hundreds of thousands of people died at the hands of this general, do I still care about the tens of thousands of people in this area?" If you fight, you will definitely die, and I gave Long'an and Wuyi City five days, and they don't want to live but die. I overtake them and just respect the dead, the dead are gone, and there is no hatred or grudge. ”

Listening to these cold words, Megumi couldn't help but feel a chill in her back.

"But dead people are always an unpleasant thing, and I don't want the incident in Wuyi City to happen again in the country of Qiuzi." Zeng Hua's words changed.

"The poor monk understood." Hui folded his palms and answered.
