Su Yi used Changgou as the first line of defense, and used the range of Qin's crossbow to constantly harass and attack the pre-war fortifications of the coalition army.

In this case, it is necessary to pay a certain price to complete the earthfill.

After observing the situation again, the adjutant general couldn't help but say: "Huang Shuai, judging from the current distance, can our army use a catapult to suppress it and provide some cover for the earth-filling soldiers?" ”

"It's not impossible, but I've always been a little apprehensive." Huang Zu frowned slightly and said, "In terms of long-range armaments, the Qin army is obviously superior to ours." ”

The adjutant general said: "The last general suggested that the stone bullet be replaced with an oil altar and use the oil altar to attack the city pass, the effect will be better, and the Qin army will definitely not dare to show its head." ”

When Huang Zu heard this, he thought about it for a while, and said: "Speaking of stone bullets, we can roll the big stone into the ditch, fill the pit with stones, and then cover the soil, so that we can also complete the fortifications faster, as for the stone throwing machine, it can only play an auxiliary role, and it cannot stop the heavy crossbow of the Qin army, and they will definitely aim the spearhead at our stone throwing machine, which is also the worry of this commander, you know, we only have twenty planes, if they are destroyed, it will have an absolute impact on the next siege war." ”

"But Huang Shuai, if this is not the case, the loss of the soldiers will be too serious." The adjutant general said urgently.

"En......" Huang Zu weighed it and said: "Okay, just do as you say, in addition, after the observation just now, although the Qin army's crossbow bed is powerful, it also has drawbacks, that is, time, after they send the crossbow, they need to prepare a lot of things, and it takes a lot of effort to reload the heavy crossbow and launch it for the second time, you also grasp this gap and make good use of this space." ”

"The Admiral understands." The adjutant general suddenly realized.

Huang Zuyi waved his hand: "Go and give the order." ”

"No!"

Next, the coalition forces no longer easily stepped into the range of Qin's crossbows, but first pushed out one after another stone throwers, and then filled the oil altar.

During this time, the Qin army had already finished loading a new round of heavy crossbows.

However, the speed of the stone throwing machine was obviously faster, and at the sound of an order, twenty stone throwing machines bounced in unison, and a row of oil jars crossed an arc in the air, smashing all over the city pass one after another.

The sound of crackling came and went, and the sparks shot in all directions, and naturally some soldiers of the Qin army were injured and burned by the explosion, and let out a terrible howl.

As the commander of the whole army, Su Yi's side was closely protected by the heavy shield for the first time, he stood behind the shield hand, and directly ordered: "Let the soldiers dodge first, protect the crossbow bed, these things are not easy to come by, there must be no damage, and at the same time, aim the heavy crossbow at the stone thrower of the coalition army, and wait for the order of the commander!" ”

"Yes!" Goldman Sachs immediately received the order, and then began to run around the city pass, shouting loudly.

Under his command, the soldiers of the Qin army bent down and ran one after another, dodging the bombardment of the oil altar, and the soldiers in charge of the heavy crossbow began to push the crossbow bed to the rear, and in front of the crossbow bed, they quickly formed a shield array.

The two sides took the long ditch as the boundary and began to engage in a long-range contest.

The oil altar projectile of the coalition army has not stopped, and after a few rounds, the deputy general couldn't help it again: "Huang Shuai, why hasn't this Qin army's heavy crossbow been launched yet?" ”

"Push the boulder into the ditch and fill in the earth." Huang Zudao.

This was an operation that had to be completed, and the allied non-commissioned officers received an order to begin transporting the big stones that were originally intended to attack the city pass to Changgou.

The whole scene looked like there were countless porters, and the stone throwers were still non-stop, filling the pit for the coalition forces.

However, when the soldiers approached the long ditch, Su Yi saw the opportunity, and with an order, the Qin army's heavy crossbow was fired again.

The six crossbow beds, which had already adjusted their orientation, were aimed at the six stone throwers, the ropes were cut off, and they were launched in unison.

Three thick crossbow arrows shot vigorously and slammed into the stone thrower, and its effect can be imagined.

In the rumbling sound, the upper part of the six stone throwers was directly penetrated, and the sawdust flew sideways, and there was also a clicking sound.

This was exactly what Huang Zu was worried about before, but the Qin army's heavy crossbow had already been fired, and it would take a lot of time to complete the second round.

Seeing this, the general of the Spirit Army, who was commanding on the front line, also hurriedly roared:

"Quick! Fast! ”

"The Qin army's heavy crossbow has been fired! It's too late to reload the bolts, and it's safe now! ”

"Quick! Hurry up! ”

Under the shouting of the generals of the various departments, the big stones were pushed into the ditch one after another, and the stone area was large enough, and filling the pit in this way could indeed have the best effect.

This ditch was dug to some depth, a row of stones, can only fill the bottom, but under the arrangement of Huang Zu, the coalition army is well prepared, not only a row of soldiers, but a lot of gathered, the first row of stones immediately retreated, and the second row followed closely to advance.

It stands to reason that now the Qin army's heavy crossbow cannot be reloaded quickly, and the coalition catapult can be withdrawn.

Seeing that the previous six planes were destroyed, the adjutant general also hurriedly said: "Huang Shuai, do you want to remove the stone thrower, otherwise the Qin army's heavy crossbow will be destroyed again after it is loaded." ”

Huang Zu shook his head slightly: "Since you have chosen to cover the soldiers to fill the soil at the cost of the stone thrower, then do so, if you withdraw now, although the Qin army's heavy crossbow cannot be launched, but without the suppression of the oil altar, they will definitely take the opportunity to release a large-scale arrow array, then this long ditch, don't think about completing it today." ”

"This ......"

The adjutant didn't know what to say anymore.

On the battlefield, the blows of the stone thrower, although they were no longer so frequent, effectively prevented the release of the Qin army's arrow array.

The non-commissioned officers of the coalition army are still racing against time, rushing to fill in the long ditch, several rows of stones are rolling down, building together, the deep ditch is almost flush with the ground, at this time, the second round of heavy crossbows of the Qin army is almost completed.

"Adjust the direction!"

There are Qin generals who drink heavily.

The soldiers in charge of the heavy crossbow began to push together, aiming the crossbow bed at the stone throwing machine below.

"Team 1 complete!"

"Team 2 is over!"

“……”

"Put!"

The sword sliced through the ropes, and the thick, sharp crossbow arrows were fired again in unison, and with the sound of breaking wind, they struck the six Coalition catapults.

Under the impact, the effect is almost the same as before, and now the crowd on the side of the ditch gathers, the stone thrower falls, and there are a small casualties.

Of course, this accuracy is not 100%, and there are two or three that shoot a little off.

At this time, the allied soldiers knew the interval between the heavy crossbows, and they all knew that it was very safe now, so they quickly stepped forward and waved their shovels desperately.

"Quick! Fill the earth—"

It didn't take long for the long ditch, which was already filled with stones, and was soon covered with new soil.

In this way, the Qin army was no longer able to prevent the completion of the coalition fortifications.

Seeing this, Su Yi at the head of the city also said flatly: "Today's battle is almost over, check the consumption of arrows and casualties." ”

Sure enough, as soon as his voice fell, it didn't take long for the sound of gold to be heard from the coalition army.
