What he saw and heard made Yang Yi firm in his previous thoughts. Passive defense is definitely a dead end, and the only way is to take the initiative to disrupt the enemy's offensive deployment and buy more time. Prometheus Star has irreplaceable strategic value, the first theater will not sit idly by, and the reinforcements that hold on to the first theater will be considered victorious. It's just that how to launch a counterattack, Yang Yi hasn't thought about it yet.

Discuss it with Shen Chengwen and them, and maybe you can come up with a solution.

Thinking so, Yang Yi walked out of the bunker.

Outside, Karl was arranging tasks for several officers and soldiers. Nothing important, just keep them on their toes and not let their minds down.

"How?" Shen Chengwen came over, and Jackson also followed.

Yang Yi shook his head and said, "It's bad, the garrison was able to hold the defensive line, not because of its strong combat strength, but because the enemy didn't launch a decent attack at all." ”

"So, we've got to solve the problem here first."

Yang Yi frowned and looked at Shen Chengwen.

"After figuring out the enemy's disposition, let's discuss it. If necessary, fight a counterattack first, so that the enemy cannot launch a large-scale offensive in the short term. Shen Cheng let out a long sigh and said, "No matter what, this military base must be defended. If the garrison is unable to hold the base after we leave, even if the South Pole base does not fall, our actions on Prometheus will be meaningless. ”

Yang Yi nodded slightly, indicating that he understood what Shen Chengwen meant.

At this time, Carl walked over.

Although he only inspected one fortress, the situation on the entire defense line was similar, and there was no need to go anywhere else, so Yang Yi decided to return to the command center.

It was at this time that the battle began.

The attack came suddenly, after Colonel Carr raised the alarm. Yang Yi, Shen Chengwen and Jackson reacted. As soon as they got into the bunker, the shells whistled and fell. The shelling lasted fifteen minutes, and the explosions never stopped.

"Don't worry, wait."

Carl stopped Yang Yi and the others and told them to stay in the bunker.

After a short lull. The shelling began again, and the explosions became more violent, and the ground shook violently, as if it was not shells that fell, but huge stones.

Yang Yi noticed that Carl and other officers and soldiers in the garrison were very calm and were inspecting weapons and equipment.

Despite being a soldier, Karl still picked up an electromagnetic gun and loaded it with armor-piercing rounds. Several other officers and soldiers after examining the electromagnetic guns. Carefully checked the protective clothing on the body. Shen Chengwen handed Yang Yi an electromagnetic gun, and Jackson also picked up an electromagnetic gun.

Because of the many casualties of officers and soldiers, the garrison did not lack individual weapons.

"Remember, shoot the head, aim before shooting, and try to conserve ammo." Karl admonished. Actually, this was said to Yang Yi and them. "After repelling the first wave of the enemy's attack, retreat to the line of defense in the rear. Don't delay, there's no need to fight the enemy to the death. ”

A moment later. The second round of enemy shelling ended.

The shelling lasted only about five minutes, and although the explosion was more violent, significantly fewer shells were dropped and the shelling area was much narrower.

"Ready? Kill! ”

Carl rushed out first, followed by several officers and soldiers guarding the fort, but Yang Yi, Shen Chengwen and Jackson pulled behind.

Rush out of cover. Yang Yi was dumbfounded, because the situation on the battlefield was completely different from what he had guessed before.

The enemy has attacked, smashed it to be precise. At the beginning of the shelling, not all shells fell, most of them were vehicles used for airdropping. When Yang Yi rushed out of the bunker. These vehicles have been opened, and hundreds of enemies are pouring out.

"Da Da Da ......"

Karl fired first, and a dense rain of bullets immediately enveloped the nearest vehicle, smashing dozens of humanoid rock demons into a sieve before they could rush out. It's just that Carl's marksmanship is extremely accurate, and although he keeps strafing, every shot accurately hits the enemy's head.

Obviously, this is the strength of the soldiers.

Compared to ordinary soldiers, soldiers not only have Origin Converters, but also have a faster reaction speed. Theoretically, the reaction speed of an eighth-level soldier is a thousand times that of an ordinary soldier, that is, the reaction time required to do an action is only one thousandth of that of an ordinary soldier. What's more, Carl has a tenth-level primordial body, and because he uses an A-level primordial energy converter, he only has the combat power of an eighth-level soldier.

At this time, Yang Yi understood why Carl used an electromagnetic gun.

Although with the combat power of a soldier, Karl can completely rush up and slash those humanoid rock demons, but using an electromagnetic gun can destroy the enemy faster.

With hundreds or thousands of enemies, speed is everything.

"Da Da Da ......"

"Da Da Da ......"

"Da Da Da ......"

……

Several officers and men guarding the fort followed Karl and formed a skirmish line, firing at the enemy who had not been killed by Karl.

Although the marksmanship of these officers and men was not comparable to that of Karl, they were all good, and they were able to kill an enemy with each shot.

At this time, Yang Yi noticed that the airdrop vehicle was actually some huge rocks, and it was also a landing craft that was extremely common in the Silicon Charm Alliance. This ovoid vehicle, which is about 100 meters in diameter, can carry 1,000 humanoid rock demons at a time, and ten vehicles can deliver a legion of humanoid rock demons.

Of course, these vehicles are single-use.

", that's exciting!"

"Da Da Da ......"

Shen Cheng roared when he heard this, and also joined the battle.

"Kill!"

Jackson also became excited, and followed Shen Chengwen to kill him.

Like Carl, both used electromagnetic guns. It's not that they don't have enough combat power, but it's more refreshing to shoot at the enemy with electromagnetic guns.

"Kill!"

Yang Yi didn't ramble anymore, and rushed forward with Shen Chengwen and Jackson.

Three soldiers appeared, making the battle a no-brainer. In the blink of an eye, the humanoid rock demon that had fallen into the vehicle less than two hundred meters from the cover was wiped out. Because the vehicle was damaged at the time of landing and could not be used again, there was no need to destroy it.

It's just that it's just a vehicle.

Although he killed a thousand humanoid rock demons in one go, it was not worth showing off at all. Because the carriers that the enemy threw near the bunker were ten!

When Yang Yi and the others killed the humanoid rock demon in this vehicle, the enemies in the other nine vehicles had already formed a phalanx.

"Don't fight hard, fight and retreat!"

Hearing Carl's shout, Yang Yi gave up the idea of charging, and Shen Chengwen and Jackson also retreated, following Carl and other officers and soldiers to retreat to the rear.

Yang Yi was a little puzzled. I don't understand why Carl is so vigilant.

In the Silicon Phantom Alliance, the humanoid rock demon is just ordinary, and its status and nature are similar to that of the human army, and they often need to rely on numbers to win. Although the other nine thousand humanoid rock demons had already formed a phalanx, Yang Yi and they were all soldiers, and it was not a problem at all to kill the nine humanoid rock demons.

"Follow me!"

Under Carl's order, the officers and soldiers guarding the fortress retreated first, while Yang Yi and the other three stayed behind to block the humanoid rock demons that began to advance with Carl.

That's too much, isn't it?

Less than two hundred meters back, a strange whistling sound was heard in the air. Immediately after, a dense barrage of shells fell.

It was indeed a cannonball, and a cannonball filled with liquid magma. Obviously, unless they hit directly, these shells are not the slightest threat to silicon-based life such as humanoid rock demons. This is a cannonball specifically designed to deal with carbon-based life, and the hot magma can burn human soldiers in an instant.

The shelling was so heavy that shells rained down.

"Run!"

Carl ran first, and Yang Yi and the other three dared to hesitate. also hurried to run wildly.

It wasn't until he ran near the back line that Karl stopped.

At this time. Yang Yi looked back and suddenly understood.

At first, if you don't retreat, but attack with the combat power of the soldiers, you will be shelled. Although it will not be killed by shells, it will be killed by intensive shelling. Even soldiers can be immobile, and then they are besieged by hundreds or thousands of humanoid rock demons.

Obviously, there is no point in counterattacking and will still be pushed back in the end.

If not soldiers, but ordinary soldiers. To fight back is to die. There is no doubt that Karl and they have suffered losses before and are well aware of the enemy's offensive tactics.

Moreover, the shelling was not just about eliminating the defenders on the defensive line.

When Yang Yi and the others retreated to the second line of defense, the shelling was still going on, and the shelling area was on the advance line of the Humanoid Rock Demon Legion, and the shells always fell within a few hundred meters in front of the Humanoid Rock Magic Array. In other words, the enemy is using this method to open the way for the humanoid rock cube, so that the area where the humanoid rock demon is located will always maintain a high temperature and will not lose its ability to move due to low temperatures.

As long as the shelling continues, the Humanoid Rock Cubes will be able to advance to the second line of defense.

And then what to do?

Yang Yi looked back and saw that Karl was communicating with the rear, looking like he was giving orders to the troops in the rear.

Is there a back-up move?

Yang Yi immediately thought that Carl and the others had repelled dozens of enemy attacks, and they knew the enemy's attack routines well, so they must have a way to repel the enemy.

More than ten minutes later, the nine humanoid rock cubes advanced to a distance of about a thousand meters from the second line of defense.

It was also at this time that the defenders' counterattack arrived.

Not to attack, but to support with long-range artillery fire.

When the shells fired by the heavy artillery fell, Yang Yi laughed and secretly breathed a sigh of relief.

Heavy artillery projected not shells designed to kill or injure the enemy, but special shells filled with liquid gas. Although the power of these shells is very limited and they cannot kill the enemy at all, the liquid gases inside leak out when they fall, causing the ambient temperature to drop dramatically.

"It seems that the defenders still have some options."

Yang Yi glanced at Shen Chengwen, nodded slightly, and at the same time prepared for battle.

On the front, dozens of defending officers and soldiers were ready for battle. The artillery bombardment kicked off the counterattack, and the next step was the complete destruction of the enemy. (To be continued......)
