Su Yi used Changgou as the first line of defense and took advantage of the range of Qin Nu to continuously harass and attack the coalition's pre-war fortifications.
In this case, a certain price must be paid to complete the filling work.
After observing the situation again, the deputy general couldn't help but said: "Shuai Huang, judging from the current distance, can our army use trebuchets to suppress it and provide some cover for the soldiers filling the soil?"
"It's not impossible, but I'm still a little worried." Huang Zu frowned slightly and said, "In terms of long-range ordnance, the Qin army is obviously better than us."
The deputy general said: "The last general suggested that the stone bombs should be replaced by oil altars, and the oil altars should be used to attack the city gates. The effect would be better, and the Qin army would definitely not dare to show their heads."
Huang Zu heard this, thought about it, and said: "Speaking of stone bullets, we can roll big stones into the ditch, fill the pit with stones, and then cover it with soil. This can also complete the fortifications faster. As for the trebuchet, it can only play a role." The auxiliary function cannot stop the Qin army's heavy crossbows, and they will definitely target our trebuchets. This is also what worries me. You know, we only have twenty. If they are destroyed, it will have a negative impact on the future. The siege battle had an absolute impact."
"But Commander Huang, if this is not the case, the casualties of the soldiers will be too serious." The deputy general said anxiously.
"Well..." Huang Zu weighed it and said: "Okay, I'll do as you say. In addition, after the observation just now, although the Qin army's crossbow bed is powerful, it also has disadvantages, that is, time. After they fire the crossbow, they need It takes a lot of preparation and a lot of effort to reload the heavy crossbow and launch it for the second time. You should also seize this gap and make good use of this gap."
"General, I understand." The deputy general suddenly realized.
Huang Zu waved his hand: "Go and pass the order."
"promise!"
Next, the coalition forces no longer easily entered the range of Qin Nu. Instead, they first pushed out the trebuchets and then filled the oil jars.
During this period of time, the Qin army had already loaded a new round of heavy crossbows.
However, the speed of the trebuchets was obviously faster. With an order, twenty trebuchets moved together, and a row of oil jars drew an arc in the air, hitting various places in the city gate one after another.
The sound of explosions came one after another, and sparks shot out. Naturally, some soldiers of the Qin army were injured and burned by the explosions, and they howled miserably.
As the commander-in-chief of the entire army, Su Yi's side was immediately protected by a heavy shield. He stood behind the shield bearer and directly ordered: "Let the soldiers take shelter first and protect the crossbow bed. These things will come when they come." It’s not easy, there must be no damage, and at the same time, aim the heavy crossbow at the coalition trebuchet and wait for my commander’s order!”
"Yes!" Goldman Sachs immediately accepted the order, and then started running around the city gate, shouting loudly.
Under his command, the soldiers of the Qin army bent down and ran to avoid the bombardment of the oil altar. The soldiers in charge of heavy crossbows began to push the crossbow bed to the rear, and a shield array was quickly formed in front of the crossbow bed.
The two sides took the long ditch as the boundary and began to engage in long-distance competition.
The coalition's oil tank projectiles never stopped. After a few rounds, the deputy general couldn't help it anymore: "Shuai Huang, why hasn't this Qin army's heavy crossbow been launched yet?"
"Push the big rocks into the ditch and fill them with soil." Huang Zu said.
This was an action that had to be completed. After receiving the order, the coalition soldiers began to transport the large rocks that were originally intended to attack the city gate to Changgou.
The whole scene looked like there were countless porters, and the trebuchets were still non-stop, filling holes to cover the coalition forces.
But when the soldiers approached Changgou, Su Yi saw the opportunity and gave the order to fire the Qin army's heavy crossbow again.
The six crossbow beds had already adjusted their directions and were aimed at the six trebuchets. The ropes were cut off and they were launched in unison.
Three thick crossbow arrows came with great force and slammed into the trebuchet. The effect can be imagined.
In the roar, the upper half of the six trebuchets were directly penetrated, and sawdust flew across the ground, making a rattling sound. The huge thing could not bear the force and fell to the ground, knocking down nearby soldiers with it.
This is what Huang Zu was worried about before, but the Qin army's heavy crossbows have already been fired, and it will take a lot of time to complete the second round.
When the general of the Spiritual Army who was commanding at the front saw this, he quickly roared:
"Quick! Quick!"
"The Qin Army's heavy crossbow has been fired! There is no time to reload the crossbow. It is very safe now!"
"Quick! Move faster!"
Under the shouts of the generals, large stones were pushed into the trench one after another. The area of the stones was large enough. This method of filling the trench would indeed have the best effect.
This ditch was dug to a certain depth, and a row of stones could only fill the bottom. However, under Huang Zu's arrangement, the coalition forces were well prepared. There was not just one row of soldiers, but a lot of them. One row immediately retreated after pushing down the stone, and the second row followed closely.
It stands to reason that now that the Qin Army's heavy crossbows cannot be loaded quickly, the coalition's trebuchets can be withdrawn.
Seeing that the previous six were destroyed, the deputy general also said quickly: "Shuai Huang, do you want to remove the trebuchets? Otherwise, the Qin army's heavy crossbows will be destroyed again after they have been loaded."
Huang Zu shook his head slightly: "Since we have chosen to use the trebuchet to cover the soldiers to fill the soil, then let's do this. If we withdraw now, the Qin army's heavy crossbows will not be able to launch, but without the oil altar to suppress them, they will definitely They will take the opportunity to release a large-scale arrow formation, so there is no chance of completing this long ditch today."
"this……"
The deputy general didn't know what to say.
On the battlefield, although the strikes of trebuchets were no longer so frequent, they effectively prevented the release of the Qin army's arrow array.
The soldiers of the coalition army were still racing against time to fill the long ditch. Several rows of stones rolled down and were piled up together. The deep ditch was almost level with the ground. At this time, the Qin army's second round of heavy crossbows was almost completed.
"Adjust direction!"
A Qin general shouted loudly.
The soldiers in charge of the heavy crossbows began to push together, aiming the spearhead of the crossbow bed at the trebuchet below.
"One team is finished!"
"The second team is finished!"
"..."
"put!"
The sword cut the rope, and the thick and sharp crossbow arrows were fired together again, with the sound of breaking wind, hitting the six trebuchets of the coalition.
After the impact, the effect was almost the same as before. In addition, people gathered at the ditch and the trebuchet fell, causing another small casualty.
Of course, this accuracy is not 100%, and there are also two or three shots that miss the mark.
At this time, the coalition soldiers knew the interval between heavy crossbows and knew that it was very safe. They quickly stepped forward and waved their shovels desperately.
"Quick! Fill in the soil quickly——"
They moved up and down together, and the manpower was so huge that it didn't take long at all. The long trench that was already filled with stones was quickly covered with new soil. The soldiers stepped forward, stepped on it, and then shoveled the soil nearby.
In this way, the Qin army could no longer prevent the completion of the coalition fortifications.
Seeing this, Su Yi at the top of the city said calmly: "Today's battle is almost over. Let's check the arrow consumption and casualties."
Sure enough, as soon as he finished speaking, not long after, the sound of gold was heard from the coalition forces.
