There are now 40,000 combat mecha warriors and more than 80,000 backup mechas, so this time, everyone is not as panicked as last time.

What's more, the current number of alloy bows is close to 30,000. Almost every mecha warrior standing on the city wall has an alloy bow, especially the mecha warrior standing on the wall of the third platform platform.

There were 5,000 fewer mecha warriors in the first wave of defense than last time, but this time no comrades were trapped outside, and everyone was prepared in advance and knew that there would be reinforcements later, which would only last for an hour at most.

, the psychological pressure I endured was much less than last time.

Ten minutes later, the black insect swarm swarmed to a range of about five kilometers in a straight line from the cliff on the third platform of the Gaishang position. Qiu Feng clearly heard the city defense crossbows beside him, and the anti-aircraft crossbows came with a "bang bang bang bang" sound.

It was a heart-wrenching sound, but it was not emitted.

The insect tide continued to approach the edge of the cliff, and the insects under the cliff began to jump more crazily towards the cliff. However, they were basically shot down by the mecha warriors standing on the edge of the cliff, regardless of whether the fallen insects were

Life or death, hitting other jumping bugs during the fall will often win the cheers of the comrades standing on the wall.

When there were only three kilometers left from the edge of the cliff, a "buzzing" sound continued to sound, and the city defense crossbows and anti-aircraft crossbows roared and flew towards the black bugs. At the same time, the mechas guarding the city wall

They collectively bent their bows toward the sky and stretched out the bowstrings of the alloy bows at a certain angle toward the outside of the wall.

Lieutenant Colonel Lu Yan has already explained to Qiu Feng that the new alloy bow and arrow fletching is designed with a one millimeter hollow alloy tube, which makes the arrow fletching strong enough. At the same time, the arrow shaft is light and the arrow cluster is heavy. Coupled with the tail feathers of synthetic materials,

The shooting accuracy is higher and the range is longer. The vertical drop of 54 meters is enough to allow the alloy bow to project a range of more than 2 kilometers.

And when the insect swarm approaches the edge of the cliff on the third level platform, standing on the top of the inner castle and shooting at a 45-degree angle, relying on the vertical drop of nearly 100 meters, can completely ensure that the arrow feathers will not accidentally damage the edge of the third level platform.

Mecha warriors, and pose a greater threat to the bugs that jump to attack the wall of the third platform.

The length of the entire alloy bow and arrow feathers exceeds 1.5 meters. When the mecha warrior fully draws the alloy bow, the arrow feathers will almost be pulled out, leaving only less than 30 centimeters in length outside the bow body. From this, it can be imagined that after these arrow feathers are fired,

The degree of damage to insects.

Moreover, the production speed of this kind of arrow feathers is very fast. The 15-meter-long arrow shafts are produced on Qi Yao Star and transported to the Cold Weapons Research Institute at the Gaishang position of Dongchu Star. The arrow clusters are cut off, welded, and the synthetic material tail feathers are pasted on, and the whole set is completed.

It is all done using mechanical automation. One production line can produce about 80,000 arrow fletchings a day and night. Currently, the Cold Weapon Research Institute has installed two production lines.

"Buzzing buzzing" waves of bow strings trembled, and the insect wave was abruptly cut off one level 2.5 kilometers away from the cliff on the third floor platform. The city defense crossbow and anti-aircraft crossbow rang again. It turned out that after shooting the third floor,

After one round, the crossbow was loaded with arrows and fired again.

It took a full thirty minutes for the insect tide to rush from a distance of five kilometers from the edge of the cliff to the bottom of the cliff. This shows how much the insects paid to break through this short five kilometers in the rain of arrows and rush to the bottom of the cliff.

, the number of bugs that started to attack the third level platform was not much more than usual.

Compared to the first insect wave nearly a month ago, the momentum was much different.

Even from the beginning of the insect wave to the present, the Seven Demon Army's mecha warriors defending the Dongchu Xinggaishang position have not suffered any casualties, assuming that the mechanical losses of the mechas due to the continuous drawing of bows and arrows are not included.

Fifty minutes after this wave of insects hit Dongchu Xinggai's position, Major General He Hai's voice rang out in the mecha channel: "Report to Marshal Guo Jiajia, the pre-war commander Major General He Hai applied to postpone the defense change time by half.

hours, and the process of moving defenses is extended to half an hour. During the half hour of the defense change, the reserve team and the main force will attack together. After half an hour, the main force will retreat to rest. Please give instructions."

Marshal Guo Jiajia, who had been standing on the top of the inner fort, immediately rotated the optical observation equipment of his mecha 360 degrees. The battle on the cliff outside the city wall of the third-level platform was still continuing. Although the insect swarm allowed jumping attacks on the third-level platform.

The number of bugs has become a bit more, but it is only about twice that of normal battles.

More bugs began to be shot about five kilometers away from the cliff on the third platform. There were not too many insect corpses piled up under the cliff on the third platform for the time being, so Marshal Guo Jiajia said: "Major General He Hai,

I agree with your request, General Chen Zhima, please pay attention to the transition of defense changes.

Before starting the rush to build the Gaixia position at noon tomorrow, try to avoid the situation where insect corpses piled up under the cliff of the third platform like last time."

"Yes!" The voices of General Chen Zhima and Major General He Hai sounded almost at the same time.

Colonel Chen Zhiyong shouted in the exclusive channel: "Report to the deputy brigade commander, I request the soldiers leading the independent regiment to jump off the cliff, use the weight of the mecha to crush the Zerg corpses currently piled under the cliff, lower the height of the Zerg corpses, and avoid

The bugs use the corpses of their companions to jump to greater heights."

Major General He Hai said: "Let's start slowly. The attacks of insects have not stopped, and the alloy bow on the top of the inner fort has not stopped shooting. If you lead thousands of mechas of the independent regiment to jump down together, there is a high possibility of accidental injury, and there are also

It may lead to the sacrifice of comrades..."

Qiu Feng's mecha has not been modified with the alloy bow aiming system, so it has been idle. At this time, he said: "Major General He Hai, inform the top of the inner fort, and coordinate with the walls of the second-level platform. On the third-level platform

The area about 500 meters to 1000 meters outside the cliff is covered with arrow feathers, and the troops are concentrated to block the follow-up of the insects. This will last for about fifteen minutes.

Warriors who can teleport, elite members of the operation to recover the Zerg brood, let's go down and clean up the Zerg corpses, empty the extra-dimensional bracelets, and crush them together."

The elite team members in the operation to recover the Zerg Brood have been recovering the Zerg Brood recently. Basically, they have not modified the aiming system of their own mecha's alloy bow, a cold weapon. They have basically just watched the nearly one-hour insect wave attack.

They had already felt itchy. Qiu Feng's suggestion was completely in line with their wishes, so everyone responded immediately.
