"Why do you have towers?"

An Wen sat down again, pulled down the periscope, and observed in the direction of the white bone spikes.

Soon, he saw more than ten kilometers away, insect nest defense towers like flower buds.

There are many of these towers and they come in different sizes.

They are all around a huge Zerg brood, protecting the Zerg brood.

Bang bang bang......

Just as An Wen was observing, the white bone spikes continued to attack him.

Although they didn't hit, they hit all around.

"it...... Who can withstand this? ”

An Wen immediately left the main turret and returned to the wheelhouse, controlling the steel war fortress to turn around.

Those Zerg towers must have a range, otherwise they would have fired a long time ago, and they would have waited until now.

As the Steel War Fortress turned around, the fungus blanket on the ground, which had not moved much, changed at this time.

I saw that the fungus blanket quickly decayed, and soon turned into a swamp like meat puree.

At the same time, the rhizomes made of flesh and blood began to wrap around the tracks.

"This Nima...... will play tactics. ”

An Wen clearly felt that the already slow speed of the Steel War Fortress had become slower.

I didn't finish this trick before, so I guess I wanted to invite you into the urn.

"This trick can deal with the Earth Dragon, but against the Steel War Fortress, it's a bit too much."

An Wen was not in a hurry, although his movement speed was slow, but that didn't mean he couldn't help it.

Coming to the gunner's position of the main gun again, and after fastening his seat belt, he began to adjust the direction of the main gun.

Soon, the muzzle of the main cannon was facing backwards, and it was a shot at the Zerg defense tower.

Rumble!

Not to mention the power of the main gun, let's just say that the reaction force of the shell when fired is more than 5,000 tons.

If the steel war fortress is fixed on the ground and does not move, it is nothing.

But right now, the steel war fortress is moving, and the reaction force of the main gun fire is directly turned into thrust, pushing the steel war fortress forward by more than ten meters.

This made the speed that had slowed down increase again.

Then, An Wen came to the secondary cannon again and kept firing.

Each time it pushes the Iron War Fortress a few meters forward without slowing down.

Call!

"Finally out of range of the Zerg Towers."

When the Zerg towers stopped attacking, An Wen breathed a sigh of relief.

To be honest, An Wen really wants to use the main cannon now to give the Zerg Hive a shot.

But think about it, if the boss in the Zerg Brood awakens directly, he really can't beat it.

It's not that the main guns of the steel war fortress are not powerful enough, but that the firepower is not enough.

To put it bluntly, if the main cannon of the Steel War Fortress is empty, then wouldn't he want GG.

So, don't be in a hurry, build the city walls first, and then talk about stacking the firepower.

Back at the exit of the tunnel, the fungus blanket here has been completely destroyed by the previous concentrated fire attack.

"Don't build small fortresses, just build large fortresses."

An Wen thought about it and decided to build a large fortress in one step.

Anyway, he didn't need much territory down there, as long as he could put those weapons down.

In this way, even if it is built instantly, the cost is within the range of Anwen's affordability.

Click to build a large fortress with a length of 500 meters.

100 meters on each side and 300 meters on the front, just enough to enclose the tunnel exit, and there is also an open space for the Truth Cannon and the Tsunami Cannon.

"Do you spend 500 million survival points to accelerate the construction of large fortresses?"

"Sure."

In an instant, a ring of walls appeared at the exit of the tunnel.

The walls of the large fortress, 22 meters high and 10 meters wide, are made of pure steel poured rock, and the overall strength is far greater than that of small fortresses.

"You have the ability to knock down my walls."

Really, after having the city wall, the sense of security is off the charts.

Then, Anwen began to install all kinds of artillery guns purchased from the store on the city wall.

On the front city wall, a swarm killer close-in defense cannon is placed every 2 meters, a total of 150 guns.

Every 10 meters, a 48-tube flaming rocket launcher is installed, for a total of 30 units.

After installing these, he also placed various mortars and recoilless guns in the spare open space.

It was not until the entire 300-meter-long, 8-meter-wide city wall that there was no more open space.

"The next time you build a city wall, you need to have a few empty floors in the middle, and the 22-meter-high city wall can be arranged with at least five layers of firepower nets, even if you can't place 48 flaming rocket launchers, but it's good to install hundreds of Gatlings."

Even if the city wall is covered with firepower, there is almost no place to foothold, and An Wen is not very satisfied.

After all, the city wall is so high, and there is no firepower point in the middle, so I always feel that I have lost something.

It's like playing a game, if there is a little empty space in his base, and he doesn't build some defense towers or something, it will be uncomfortable.

Finally, behind the city walls, An Wen installed a Truth Cannon and two Tsunami Cannons.

With all that done, he was once again on top of the Iron War Fortress.

In the past, when the walls were built, it was the Iron War Fortress that fended off the attacks of monsters, but now it is useless.

"The Iron War Fortress is useless, let it explore the way."

Press the joystick to turn all weapons except the main and secondary guns to auto attack, and then An Wen exits through the escape exit of the territory.

In this way, the Iron War Fortress rushed towards the Zerg Brood without hesitation.

"You can go without worry, I'll give you fire cover."

An Wen looked at the distant war fortress, directly controlled the tsunami cannon, and carried out a wave of concentrated fire on the monster group in front of it.

If you are poor, tactics are interspersed, and when you are up, you will blow up Lao Tzu.

Now, Anwen belongs to the level of the nouveau riche.

With the opening of the shop, he can already play with fire coverage.

Rumble!

Rumble!

Rumble!

The tsunami cannon roared with three rows of 680-millimeter cannons.

Then, An Wen saw the nine shells open in the sky, and 2,700 split warheads fell from the sky like splashing water.

Rumble!

The first wave of 900 split warheads covered 1 km of the ground and directly erupted into a flame shock wave.

The second wave of 900 split warheads, followed by the first wave of fire, exploded again, making the flame shock wave even more huge.

The third wave of 900 split warheads exploded, and the three flame shock waves merged into one, directly turning into a flaming tsunami, sweeping everything in front of it.

Not to mention the monsters, even the thick fungus blanket on the ground was directly exploded.

"Cool, that's the effect, fry it for Lao Tzu."

The weapons on the walls also opened fire, and the monsters were organized to approach the steel war fortress.

An Wen didn't care about any of this, he had already arrived in the control room of the Truth Cannon.

The Truth Cannon did not participate in the suppression of firepower, and its muzzle was aimed directly at the Zerg brood, waiting for the appearance of the boss.

As the Iron War Fortress gets closer to the Zerg brood.

The Zerg towers also attacked.

To be honest, the accuracy of the Zerg defense tower is really not high.

It's like standing still and spitting at an ant's nest five meters away, and if you spit dozens of times, you won't necessarily hit the ant's nest.

Whoosh ......

When the Zerg defense tower attacked, the 30 48-tube flaming rocket launchers on the city wall also followed.

1,440 rockets, launched rapidly, and a barrage in the sky.

Boom Boom Boom ......

The entire defense towers around the Zerg Hive were all attacked at this moment.

To be honest, seeing such a scene, An Wen felt that the firepower of the Zerg Brood was a bit poor, and this design was unreasonable.

It's too simple to fight the monsters around the boss like this.

Hiss!!!

With the destruction of the towers around the hive, the boss inside the Zerg brood finally makes a sound.

The huge Zerg brood began to shrink, and the special effects were just like the first boss.

"It turns out that the appearance mechanism of this boss is that the surrounding defense towers are destroyed before it appears."

An Wen squinted his eyes and muttered, not surprised by the current situation.

Besides, it's good for the boss to come out.

The muzzle of the Truth Cannon, but it has been aimed at the Zerg brood.

With the end of the special effect of the boss appearance of more than ten seconds, the huge and hideous BOSS tore the Zerg brood and crawled out of it.

Hiss!

It raised its head to the sky and roared, announcing its presence, as if to say: I'm here!

"It's now."

An Wen pressed the fire button.

Rumble!

The ground trembled.

The 9.3-ton cannonball of the Truth Cannon shot straight at the boss.

At this time, the boss finished hissing and looked down at the Iron War Fortress that was slowly heading towards it.

There was a hint of disdain on its hideous face.

But the next second, it sensed that something was wrong, and as soon as it looked up, it saw a huge cannonball, which kept magnifying in its compound eye.

Rumble!!!

There was another loud roar.

The earth trembled, and a sky-high fire appeared in the place where the boss was located.

Although An Wen can't see the specific situation of the boss, he can see the blood bar.

In his eyes, the BOSS's high-end blood bar with a purple-gold frame disappeared in an instant as if it had been magical.

-9999999999

The health bar is instantly emptied.

"What's that? The boss was ...... Was it seconds? ”

An Wen was stunned.

This boss only appeared in a few seconds, and it was just seconded.
