With several waves of arrow feathers and zipline tripstones, not a single 'red-spotted ghost spider' could break out until the smoke subsided.

Even the second team of 'Pollution Demons', who had just come to the city wall by hitchhiking, had a close contact with the ground under the corner of the wall because their mounts were suddenly knocked off the wall.

A few minutes is not a long time, but it is a life-saving time for the current defensive line.

The next moment when the smoke cleared, the troops who came to support finally came to the defensive line, although there were not many of them, judging from the dust and sharp aura on their bodies, all of them were elite.

Long before this siege, the Commander had issued an order to immediately send a magical message for all teams out to scout and clean up to immediately return to support.

And this section of defense line where Chen Yuan is located, after delaying the battle situation until now, finally waited for the arrival of reinforcements.

The melee group, which had been replenished in numbers, immediately rearranged its formation to form a defensive line, and the lack of thickness of the defensive line caused by the personnel damaged in battle had been compensated, and the crisis of the collapse of the defensive line was resolved without leaving a gap.

The wounded ranged crew also took advantage of this opportunity to retreat in search of medical treatment, and the vacated positions were filled by support troops, and the total number of people was even much higher than at the beginning, and the firepower was further improved.

'Click'

Removing the shackles of the belt and control grip, the controllers on the three 'Magic Crystal Cannons' jumped directly from the cannons, and the ammunition of the 'Magic Crystal Cannon' has been exhausted, and even if they are not finished, the barrels that have been heated to red will not allow them to continue firing, and the risk of firing in the case of overheating is extremely high.

The base of the 'Magic Crystal Cannon' shook for a while, and with the click of mechanical gears, the 'Magic Crystal Cannon' actually slowly rotated and fell into the city wall from the crack that was separated from the base, and when the cannon was completely submerged in the space inside the wall, the separated rift closed again.

"This works..... It's a little something.,It's not like the style of the forest elves at all.。 ”

Chen Yuan could see clearly from the watchtower, the circular base of the 'Demon Crystal Cannon' was actually liftable, and he had stayed near this cannon for most of the past few days without discovering the secret of its bottom.

If you want to talk about style, in Chen Yuan's cognition, it is the craftsmanship of the dwarves that can match the picture just now, and the forest elves are too disobedient.

Without the 'Magic Crystal Cannon', there are good and bad things for the battle situation.

The good thing is that the squad responsible for protecting the cannon has been lifted and can become a support team that moves between the near and far groups, counting the team led by the commander, there are four wandering support teams in the entire section of the defense line at this time, which greatly improves the error tolerance rate of the defense line and reduces the pressure on the melee defense line.

The worst part is the loss of ranged firepower, which will lead to more enemies storming the line than before, and the survival rate of elite units in the enemy line will increase significantly.

The ceasefire of the 'Magic Crystal Cannon' had a particularly great impact on Chen Yuan.

At this time, Chen Yuan wished that he could have one more head and two hands, just one person and one shot couldn't take care of it at all, the elite units on the hundred-meter-wide defense line that were rushing with the enemy tide and the special units that had achieved the 'Pollution Demon' were like a certain music game he had played in his previous life, or the hellish difficulty of the difficult tracks!

As soon as he sniped a giant spider on the left, the two special spiders on the right jumped onto the wall with several 'pollution demons', and they couldn't stop it at all.

Fortunately, the ammunition reserves are sufficient, which is the only good news that Chen Yuan can think of now and the courage to continue fighting.

The increase in the pressure on the defensive line also gave Apollo a wider space to play, and all the elite units and 'polluting demons' that were missed by Chen Yuan were all blocked by Apollo with a 'fire hammer' on the muzzle of the gun for 'education'.

After changing the Wide Area Strike mode, Apollo can even block a ten-meter-wide defense line single-handedly with the 'Fire Hammer', and the lead bullet with the burst attribute and optimized structure is a big hole as long as it is hit, and can also further kill the enemy's body with high temperature after shattering the outer armor.

If it weren't for the slow reload, Apollo would have been able to kill all sides in this campaign.

.....

Wave after wave of enemies were repulsed, and the reinforcements that arrived one after another quickly stabilized the various defense lines that were on the verge of collapse, and seeing that the battle situation was about to tilt towards the forest elves, the commander standing on the command tower behind the city wall slowly breathed a sigh of relief.

The situation was really similar to what he expected, as long as he held on for a while, there was nothing to fear about the remaining 'Black Abyss' troops.

"What is the consumption of the 'Magic Crystal Cannon' this time?"

"Head, the thirty 'magic crystal cannons' have consumed a total of twenty 'Star Diamonds' and more than nine hundred rounds of ammunition this time, and we currently only have six 'Star Diamonds' and less than four hundred rounds of ammunition left."

Rubbing his temples with a headache, the commander was also a little helpless.

The energy and ammunition required to use the 'Magic Crystal Cannon' have always been in high demand in the clan, and it takes a lot of time and manpower to transport them.

I only replenished it once last month, but I didn't expect that a month was not over, and the remaining ammunition under my command after this battle was not enough to support another large-scale operation.

"What does the headquarters say?"

"For the time being, the headquarters only responded to let us try to save the use of ammunition and energy, and each theater is now short of resources, and they have no extra resources to distribute to us again for the time being." The supervisor in charge of communication and logistics could only answer helplessly in the face of the chief.

Everyone knows that heavy fortification weapons require scarce resources, but if you don't use fortification weapons to provide firepower reinforcements in a major battle, the battle damage will be too large, which is really a headache.

"Immediately after the end of this battle, twice as many 'shadow guards' will be scattered around, and once there is a big movement on the opposite side, it will be transmitted back immediately."

"Understood."

.....

Shattering the compound eyes of the 'Red Spotted Ghost Spider' in front of him with a single shot, Apollo retreated to the defense line under the cover of his teammates to catch his breath.

The 'Fire Hammer' is not lightweight, and it was originally designed to deal with explosive short battles, and the physical burden on the user during long battles is not small.

And in order to avoid the attack of the 'Red Spotted Ghost Spider', Apollo's physical exertion slipped exponentially, and until now, he basically had to withdraw and rest after two waves of lead bullets.

There had been no gunshots on the watchtower for a while, and although Apollo was a little puzzled, the stalemate did not give him a chance to think about it, so he could only struggle to cope with the further pressure.

At this time, Chen Yuan's cold sweat on the watchtower slipped down his cheeks drop by drop.

He was at the highest point of the battlefield, no matter what abnormalities and changes in the enemy formation were, he naturally couldn't escape his eyes, and just three minutes ago, a humanoid 'Black Abyss' force that suddenly appeared from the side of a certain mountain wall suddenly broke into Chen Yuan's field of vision.

The moment he saw it, Chen Yuan's pupils couldn't stop shrinking, and the cold sweat from his head and his body frozen in place made Chen Yuan's expression look so frightened at this time.

"Impossible!"

"Why! Why did the 'Black Abyss' that would only appear after more than half a year appear here! ”

"Aren't they supposed to break through a battlefield and attack the clan land in more than half a year!"

The 'Black Abyss' elite unit that should have appeared and attacked Apollo's hometown after more than half a year, the 'Shadow Hunter', suddenly came out as a reinforcement at this moment, which not only stuffed a big question mark in Chen Yuan's mind, but also made the commander on the rear command tower instantly chill, like an ice cellar.

Biting his tongue fiercely, Chen Yuan had no other way than to use the change of plot as an explanation, and the most important thing now was to delay the time for the 'Shadow Hunter' troops to attack the city wall.

The cold fingers were pressed on the trigger again, and Chen Yuan fired at the 'Black Abyss' elite troops in the distance with full skill.

The gunfire above his head in the rear came again, and the frequency became much faster, and Apollo realized that something might have happened, but the enemy in front of him was still attacking without fear of death, and even if something happened, he was powerless to stop it.

"Head, the 'Shadowhunters', ..... we?"

"Fire."

"Sir, the 'Magic Crystal Cannon' has only cooled down by a third." The manager in charge of overhauling the cannon spoke.

"I'll let you, fire!"

"Yes."

On the city wall, the click sounded again, and in the confusion of everyone, the 'Magic Crystal Cannon' rose from the wall again, and all the personnel who controlled the 'Magic Crystal Cannon' also received the magic message and immediately climbed into the control room.

The 'Crystal Cannon' was raised, and the three teams of wandering support teams had to return to guarding the cannons, and the defense line could only retreat some distance to relieve the pressure.

Everyone on the battlefield didn't even know what was happening, but the sudden rise of the 'magic crystal cannon' during the cooldown period still made everyone guess the danger coming.

For a while, a little panic began to appear in the minds of the recruits, and the veterans' faces became much gloomy.

"Don't panic! There are not many of them anymore, and even reinforcements will not be able to break through our lines. ”

"The second batch of reinforcements is coming, as long as we hold on, we will win....."

"Our defenses have been held for so many years without being breached, and this time it will definitely be fine! .....”

The commanders in charge of the command of each section of the defense line have stabilized the morale of the army, and they have been defending it for so many years, and there are more than this time when there are accidents, and their confidence in the defense line is still very sufficient.

The veterans also gradually eased up, and they naturally had a better mental quality after many battles, which also drove the recruits on the side, and the various defensive lines that had just generated a little riot returned to normal after a while, and then dealt with the attack of the remnants of the 'Red Spotted Ghost Spider' troops in an orderly manner.
