The vibration under his feet is becoming more and more obvious, and it is actually coming from behind!

"What's the situation, is there a riot in the fortress?"

As soon as the fat man finished speaking, he saw the upper part of the giant pyramid dome gradually open, revealing a huge cannon barrel. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The barrel alone is 100 meters long, and the caliber is enough to accommodate the passage of a train, like a tunnel. The soldiers present all exclaimed, even the fat man, who had no idea for half a year that there was such a big killing weapon on top of their heads.

After the giant cannon was erected, it immediately entered a state of charging, and almost one-third of all the energy storage crystals on the pyramid's heavenly dome instantly dimmed.

"Funds are burning!" the fat man said with a wry smile, he was in charge of the supplies very well in his heart, no matter whether the defense succeeded or failed, he would squander the savings of the fortress in the past six months.

In the past half a year, the fortress has only saved a total of less than 500 energy storage crystals, all of which are of red quality, and the energy of one energy storage crystal is equivalent to the entire energy in the body of a level 8 evolutionary.

There were a total of 300 of these energy storage crystals embedded in the heavenly dome, and one-third of the energy was concentrated, which was more than the energy in the body of a level 10 evolutionary.

Watching the white light gradually glow from the barrel, everyone wondered what would come out of it.

"Isn't it pretty? Don't blame me for being blinded by a flash of eyesight. ”

Just when everyone was very curious about this big guy, Qiu Qian also happened to come to the wall outside the fortress, and with him was Snow Shadow.

"Qiu Qian, I finally know why the resources of our union are always tight, and it turns out that we have been raising this thing. The fat man was pointing on the surface, but he actually admired Qiu Qian's ability.

"It's a good thing I got the ability of khaki, otherwise with our people, let alone this giant cannon, we wouldn't even be able to build a wall. ”

Although Qiu Qian is now khaki's appearance, she is actually not disgusted. To be honest, Khaki looks much better than Qiu Qian in terms of figure and appearance, as long as he doesn't look through those dirty memories in Khaki's mind, Qiu Qian has made a lot of money in general.

"Looks like there might be hope to hold on this time!" Rams said.

"Who knows?" Qiu Qian didn't want to say anything to discourage her, and she didn't want to say anything to lie to herself.

"The first batch of monsters will soon be within range of the main guns, but I'll wait until they reach a certain number before firing, and then I'll want you to hold on for 10 minutes, and then Snow Shadow and I will do the rest. Qiu Qian ordered.

"Sir, don't say ten minutes, even if it's an hour. An unknown soldier said.

"No, you will retreat to the fortress as soon as the time comes...... The time to save is in the way. Qiu Qian showed the domineering spirit that a commander should have.

Ten minutes passed quickly, and the sky was already completely dark, and a large red fire finally appeared on the horizon in the distance.

"It's pretty smart to have magma worms play the strikers. ”

Today's earth has long since become a world of monsters, and such invasions of human settlements occur every day.

During the Doomsday War, a total of 5 high-level monsters came out from the 23rd plane, four candidates for the 8th order and one 9th order guard. The world's strongest evolutionaries have joined the battle.

Due to the absence of Arthur, an evolutionary who has almost reached the advanced level of the planet, the human race, which is already at a disadvantage, has become more passive. The final result was that the human race lost almost all of the Evolvers above level 10 before killing the Tier 8 guards and seriously injuring the Tier 9 guards.

The loss of more than half of the combat power just after the start of the war is too much for humanity to bear. They realized that with the current strength of the human race, it would be a fool's dream to capture the Tower of the Nativity.

Although the high-level monsters were defeated, an overwhelming number of monsters immediately poured out of the forbidden area, and that was the Dimensional Legion. The human beings who wanted to stay in the green mountains finally started the "evacuation plan".

Use each city as a base to build fortresses one after another, resist the attacks of various monsters, and improve your own strength while waiting for the day of counterattack.

There are two types of attacking monsters, one is the plane legion, and the other is the primordial creature of the small plane.

The Plane Legions expand from the Tower of the Birth and attack the fortresses along the way. If the defense is successful, you will have a safety period of about a month, and if you lose it, you will have to retreat to the rear fortress farther away from the Nativity Tower. Plane Legion monsters are usually of a low level, but each attack is huge in number and periodic.

As for the creatures of the small planes, they are all over the world. The entrances of the small planes that overlap all over the solar system are unsealed one after another under the impact of the huge energy of the birthplace, causing many small-plane creatures to haunt the birthplace. Although their strength is generally above the planetary level, fortunately, most of them will not take the initiative to attack the fortress.

There are dangers, but there are also opportunities. After the Doomsday War, the energy density of the entire Birthplace was increased to the same level as in the forbidden area, greatly increasing the growth rate of the Evolver. At the same time, although those monsters are dangerous, if you can kill them, you can get a lot of treasures from the corpses of the monsters.

On the one hand, it is to directly peel off specific tissues to produce various products, or to extract energy cores from their corpses and use them to make energy storage crystals.

In the face of a large-scale monster invasion, everyone will be scared, but once the defense can be successful, the mountain of corpses will be the best trophy. A successful defense can greatly improve the overall strength of this fortress.

It's just that for Qiu Qian, there are too many monsters in front of her.

The number of monsters is more than 150,000, and the average is around the beginning of the asteroid. The main gun of the fortress can launch 2 attacks, and it is conservatively estimated that it can kill 40,000 units. The Mech Legion should be able to kill around 20,000 units. Snow Shadow and I are normally able to kill more than 10,000 units. The current strength of the fortress can defend against an invasion of up to 50,000, which is not enough!

Despite the overwhelming army, Qiu Qian was still calmly calculating.

If you adopt more aggressive tactics, abandon the defensive function of the steel dome, and directly let the main gun fire 3 times, you can kill about 50,000. Let the soldiers defend the city walls, which can resist at least 80,000 ...... No, we can't let them die like this.

Qiu Qian is not a woman's benevolence, but such a sacrifice is meaningless, and will only further reduce the overall strength of the Eternal Guild.

If only the Snow Shadow ...... No! No!

"Sir, the vanguard of the monsters is still 2 kilometers away from reaching the wall, and they are already within range of their weapons. ”

"All hands attack, defensive weapon array firepower!"

Qiu Qian gave an order, and all the evolutionaries on the city wall used their respective skills to attack the monsters in the distance. Tens of thousands of attacks in different ways, a dazzling array of attacks surged towards the magma worms like a tsunami.

At the same time, Qiu Qian also used her spiritual power to control the anti-weapon array on the city wall, and frantically tilted the cannon fire towards the attacking monsters.

The magma worm's self-detonation ability is a great threat to defenses, and many fortresses have suffered a lot. However, their defensive capabilities were not very high, and it didn't take long for them to become a wreckage under the baptism of tens of thousands of evolutionaries and fortress defense weapons.

"Sun Tao, help me take a look at the monster behind?" Qiu Qian asked.

"Well, scorpions, elite skeletons...... There are still flocks of strange birds in the sky!" Qiu Qian hurriedly looked up and saw that there were hundreds of thousands of wings flying towards them quickly.

If hundreds of four wings spit out corrosive liquid at the same time, it is definitely a big problem and must be solved first. At this moment, the main cannon has already been fully charged, but it can't achieve the maximum killing effect when used now.

"Turn on the Earth Force Field Shield, apply the Damage Reflection Shield to the Fat Man, and all the rest, attack the enemy in the air!"

The defense array was replaced with a new energy storage crystal, and immediately shot rows of lasers into the sky, and the anti-aircraft missiles also rose into the air at the same time, and with the cooperation of the evolutionary, hundreds of four wings were knocked down.

For now, the situation is not out of control. It would take a few minutes for the next wave of flying monsters to enter the firing range, but the ground troops slapped the wall like a wave, and the instant impact that erupted made the fat man let out a painful sound.

"How's that? Can it last 10 minutes?"

"Yes!" the fat man laughed.

Qiu Qian watched the green tendons on the fat man's head bulge, and she couldn't rest assured. With such a large number of monster invasions, it was the first time Qiu Qian had experienced it, and it was inevitable that there would be errors in the calculation.

Although the black and oppressive monsters under the wall are all only in the primary stage of asteroids, quantitative changes cause qualitative changes. With the strength of the fat man, I am afraid that it will be difficult to hold on for 10 minutes under an attack of this intensity.

"All Evolvers begin to destroy ground targets, and the defensive weapon array maintains the highest power output to attack air units!"
