On the Nanxiu Beacon Line, the Chu army dug a pit, the Vietnamese army filled the pit, and the two sides fell into an endless tug-of-war. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoFor ten days in a row, the 9 billion Yue army advanced less than ten miles. I don't know how many pits have to be filled.

After ten days of fighting, Zhou Ziwei already understood that the Chu army wanted to use the layers of defense lines prepared in advance to consume time and wait for the decisive battle of Chu and Song in the north to divide the victory.

Metropolitan Governor Zhou Ziwei is not a mediocre person. At the strategic level, since the enemy insists on it, he must oppose it.

However, the location of Nanxiu City is very special, it is stuck in the Gongga Pass, and both wings are towering dangerous peaks, which is not conducive to the breakthrough of the large army. Although there was no shortage of mountain combat units in the Vietnamese army, they could only attack in small units and were difficult to deploy.

Lu Ning, the commander of the Southern Expeditionary Army of Chu, deployed two armies on the mountain peak early, although the number was small, it was enough to resist the Vietnamese troops who were attacking from the dangerous path and forced the Vietnamese army to break through head-on.

Soon, Zhou Ziwei found a way to speed up the filling of the pit.

A huge arsenal rose up behind the barracks, a large number of giant trees at the southern foot of Gongga Mountain were cut down and transported to the barracks, copper and iron ingots transported from the rear were piled up, and the sound of forging in the forging workshop within a radius of dozens of miles was deafening all night.

Large boulders more than a person high were mined from the mountains and sent to the front of the barracks in an endless stream.

Within five days, tens of thousands of giant trebuchets stood two arrows away from the trench. At the command of Gan Bailu, the former army general, the winch rolled, the throwing rod was erected like a jungle, and tens of thousands of boulders roared and threw themselves into the trench.

The trench was so wide that even without aiming, most of the stones fell into it, and smashed into the deep ground, and the earth trembled with a loud rumbling sound like thunder, and the dust flew up.

Because the distance was too far, the Chu army's bows and crossbows on the fortress mountain could not attack, and only a few trebuchets could bombard the trebuchet positions of the Yue State by taking advantage of the geographical advantage. Most of them were blocked by a specially made oversized shield in front of the formation, causing extremely limited damage.

Occasionally, a boulder crosses the shield line and smashes into the beam of a giant trebuchet. With a tooth-aching crackling sound, the trebuchet snapped at the waist. The rod fell, knocking over another trebuchet.

However, without waiting for the soldiers of the Chu State to cheer, three new trebuchets were pushed from behind the formation and replenished into the trebuchet forest.

In less than half a day, the trench that the Chu army had worked so hard to dig was filled with boulders. Gan Bailu did not stop, but ordered the trebuchet to move forward as a whole, and began to bombard the fortress mountain with boulders.

This trick really worked, and the fortress mountain made of earth was crumbled under the intensive bombardment of hundreds of thousands of boulders in multiple rounds, and even the armor of the dark fortress arranged on it was destroyed.

The Chu army, which was ambushed on the fortress hill, had to retreat in a hurry and give way to this line of defense.

Song Jun cheered and swarmed up. The Lux goalkeeper dragged the boulder back to the position. The digging army worked hard to dig up the dirt mountain, and it didn't take long to dig hundreds of passages into the fortress mountain. The front army pushed the trebuchet and continued forward, and soon launched an attack on the second line of defense.

Within three days, the Song army had filled in five trenches and advanced twenty miles. Zhou Ziwei got the report from the front line and smiled slightly:

"I have broken the defensive technique of breaking the skill with strength, overpowering the crowd, and matching the trench with the fortress mountain. Lu Ning, let's see what tricks you have again?"

As expected, Zhou Ziwei quickly found a way to crack it. Lu Ning smiled:

"At this rate, in less than a month, the Vietnamese army will be able to break through all the outer positions of our army and enter the inner line to attack. This is not in line with our army's plan. ”

Senior General Han Weiwu hurriedly said: "Marshal, this is not in line with the instructions of the military department. Don't we have a secret weapon? just bomb them and break the trebuchet. ”

Lu Ning shook his head and said, "Don't worry, good steel always has to be left on the blade." Tell the front to throw a cluster grenade with a trebuchet to scare them first. ”

The next day, there were also more trebuchets on the mountains of the Chu defense line.

Gan Bailu squinted his eyes and looked up at a row of trebuchets standing high on the fortress mountain, and sneered: "Tell the brothers to be on guard, the Chu army is about to come out with a moth." ”

Sure enough, when the trebuchet array of the Yue Kingdom began to fill the pit again, the trebuchet of the Chu army also began to project. This time, instead of a monolith, a whole boulder was projected, but a pile of black things.

The pile flew halfway and suddenly spread out, turning into hundreds of small balls the size of goose eggs. Hundreds of trebuchets were launched at once, and the small black balls flying in the air were densely packed, and there were tens of thousands of them.

Because the portion is relatively light. These small balls were thrown far longer than the stone-throwing, and even directly crossed the shield of the Vietnamese army and fell into the trebuchet position.

As soon as the small round ball called the "grenade" hit the ground, it exploded violently, with flames flying and shrapnel in all directions.

Caught off guard, the pitchers who operated the trebuchet were hit hard, and in an instant, nearly 10,000 people were injured by the explosion and shrapnel, and they wailed incessantly.

These grenades are not as useful as imagined for warriors above the elite level. Flying shrapnel can hurt people, but it is rarely fatal. What is truly fatal is the damage done to the trebuchet by the grenade explosion.

These huge war equipment, mainly made of wood, were bombarded by shrapnel, and the mechanisms were extremely damaged. In addition, the explosion ignited the wooden racket pole, and hundreds of catapults suddenly ignited a raging fire.

Seeing that the grenade was effective, the Chu army, which had been aggrieved for a few days on the fortress mountain, let out a burst of cheers, and the cluster grenades were thrown more frequently. Because of the dense position, even the trebuchets that were not bombed were ignited, and soon the trebuchet positions of the Yue country were in flames.

The Vietnamese slingers, who had just been proud for a few days, held their heads and covered their wounds, and retreated in embarrassment, allowing most of the tens of thousands of trebuchets to be burned down.

"It's a good move, but it's not enough for class. Zhou Ziwei was not frustrated by the destruction of the trebuchet array, but with great interest, he held a dumb grenade and looked at it repeatedly in front of him.

As a top-level hero-level existence, they all have a strong qi to protect themselves, and a small grenade cannot pose any threat to Zhou Ziwei.

"Hand grenade? Is this the secret weapon of the Chu State? There are no runes, not magic weapons. ”

Swinging his palm to volley everything, the grenade was split in half by the flesh palm, revealing the black powder in the middle, the detonator. Zhou Ziwei looked at it carefully, picked up a handful of black gunpowder, sniffed it on the tip of his nose, and frowned slightly:

"The disgusting smell is a technical creation of scientific and technological civilization, and it seems that it is still something created by Gu Wen, the dying strategist of Chu State. ”

Overseer Yu Shi Xiao said: "Gu Wen is a consultant, a talented but disloyal profession. No wonder he did so many things, but he was easily abandoned by Xiang Yan. ”

Zhou Ziwei sighed: "It would be good if the three major factions had done it earlier." Even if Gu Wen this guy is going to die, the pile of things he invented will give Chu Guo an extra chance of winning. ”

"But right now, this little trick is not enough for me. ”

Soon, the Vietnamese troops began to counterattack. Intermediate one-way isolation circles were carved out in front of the newly built trebuchet group.

These one-way magic circles are not very powerful, and they can't even withstand the full force of the high-level heroes. However, it is enough to resist very light grenades.

A large number of cluster grenades retreated in front of the isolation array, and were bounced into the open ground and exploded, without causing much damage to the Vietnamese army. Only a handful of grenades scattered high enough did they cross the circle, causing minimal damage.

Seeing that the frontal attack was ineffective, the Chu slinger changed the elevation angle of the trebuchet and used a higher parabola to bombard the Vietnamese trebuchet position, but still achieved some results.

But soon, Zhou Ziwei ordered someone to erect an elevated highway and deployed the isolation circle to a high altitude.

As a result, the cluster grenades were largely ineffective. It took two days for the Vietnamese troops to once again flatten the trench in front of them and win another victory.

Next, the two sides have frequent wisdom opportunities. Lu Ning sent an elite death squad to destroy the isolation array, and planted fire oil mines in advance at the location of the trebuchet. Zhou Ziwei also sent an elite protection circle and intensified the underground exploration of the trebuchet position.

Then the Gu Clan's poisonous dragon thorn confronted the steel shield of the multi-person rune array, and the burning urn collided with the rocket array, and various combat techniques and tactics emerged in endlessly. In the past half a month, the two sides have fought dozens of times, each with its own winners and losers.

However, relying on the absolute superiority in numbers, the Vietnamese army is still advancing at a slow pace.

A month later, three-quarters of the hundreds of miles of trenches that the southern Chu army had worked hard to dig for half a year had been filled. It was only a matter of time before the rest was filled in.

Feeling that the opponent's methods were already a little old-fashioned, Zhou Ziwei's face became more and more like Zhizhu in hand.

However, Lu Ning didn't seem to be anxious, he had already prepared a big gift, and he wanted to invite this good guy to taste it. (To be continued.) )
