"When we get out, we have to find a way to build a main tower no matter what!"

Cheng Shen said in his heart.

He had always had a desire to go with the flow of the main tower.

Take it when you come, and don't force it if you don't come.

Now it seems that it was just wrong.

In the first edition of the intelligence book originally released by the Alliance, some of the attributes of the main tower were absolutely hidden, so that it created the illusion that the main tower was nothing more than a strengthened rare-level defense tower.

It was only at this moment that he realized the importance of the main tower.

With the main tower, the other towers are all support, and now it's a bit unbelievable to think that he can survive with a bunch of towers.

Cheng Shen understands,

It was all by throwing money at it......

Once you have a clear idea, the choice of the fourth wave of towers is simple.

Cheng Shen directly selected two of them.

【Sunfall】

【Hred】

[Level: Rare]

[Level: 1]

[Energy: 0/200]

[Recovery: 10]

[Cost: 50]

[Range: 60]

[Characteristics: Summons a fire meteorite to attack enemies within a 5x5 radius, dealing 120 fire damage and creating a lava flow area that lasts for 3 seconds, slowing enemies passing through the area by 30% and taking 30 fire burns per second]

……

【Foul-smelling cyst】

【Abyss】

[Level: Rare]

[Level: 1]

[Attack: 0]

[Attack Speed: 0]

[Range: 30]

[Characteristics: The foul stink cyst will continue to spit out pus, covering ten blocks of the ground, slowing enemies in its path by 35%, and has a 20% chance of spreading the cyst virus for them, only effective for biological units]

……

Cheng Shen chose an abyss tower that was as disgusting as the blindness epidemic.

Just let the two of them match each other.

There is also a sacred tower.

Sunfall's Fire Meteorite skill costs 50 energy to be released, and its base recovery rate is 10 points per second.

That's every five seconds.

Cheng Shen then used the crystal energy talisman on the crystal, and the results of the four waves made the crystal energy talisman increase the energy recovery speed by 4 points for the whole.

This time.

Increases Sunfall's attack speed to 3.5 seconds.

Moreover, sacred towers generally have a trait that is not considered hidden.

The higher the energy cost, the stronger the effect of the skill.

If Sunfall releases a Fire Meteorite with 100 energy, its damage and burn effects are doubled.

Up to three times more.

A Tier 1 Sunfall at full energy can deal 480 direct fire damage and a total of 1440 burn damage for 12 seconds.

It is definitely a first-class existence among defense towers of its class.

You know,

Sunfall is able to regenerate energy while in standby.

In other words, its first attack after entering the battle must be a double critical hit with full energy.

This blow could change the course of a defensive battle.

"Why are the towers of other departments so strong......"

Cheng Shen tugged at the corners of his mouth.

The more you know.

The more he has opinions about his defensive lineup.

maybe

This is exactly the mindset of parents when they talk about "other people's children......

Sunfall's slow effect does not overlap with Vicious Cysts and Blindness Plague.

It only extends the scope of control.

At this time, Cheng Shen's control system for this lineup has been established quite perfectly: paralysis, blindness, slowdown, imprisonment, and some effects have more than one effect, plus the attack resistance of the Dark Thunder Mage.

There are also two runes that have a bonus.

It's almost on par with the defensive lineup in his territory.

With this arrangement, if he can't beat the fifth wave, Cheng Shen will have to seriously consider whether to continue to use the acceleration scroll today.

Keep up the challenge!

Thundered......

There was a heavy muffled sound behind the whirlpool, as if some kind of behemoth was moving.

[The fifth wave of Void Challenge monsters has struck!] 】

[This attacker: Troll/Flame Wings!] 】

[Quantity: 481!] 】

【Warning! This time, there is a boss unit in the siege enemy, and the presence of the boss will greatly increase the desire of ordinary enemies to attack, so please kill them first! The boss unit that appears this time is: Fanatic Troll! 】

……

A huge figure nearly five meters tall emerged behind the whirlpool, its face was ugly, its eyes were cloudy, its skin was like rough pigskin, it was covered with messy hair, and a mouthful of moth-eaten yellow rotten teeth were revealed in the crooked corners of its mouth.

It carried a huge chainsaw about three meters long on its shoulder, and the blade of the saw was dark brown with blood clots and scarred flesh and bones.

"Wu Mosado!!"

It roared, and all sorts of strange monsters, which looked ugly but ugly, suddenly poured out of the whirlpool like a tide.

These ordinary trolls are also two meters tall.

In his hand, he carried a bone club, a battle axe, and a spear...... Although they are all decorations for Cheng Shen, it is a symbol of their attack power, even if they miss one, the damage caused to the crystal is not as simple as 1 point.

In the face of the attack, the miserable green poisonous fog was the first to spread.

Wow!

Like a foul-smelling cyst of a wriggling maggot, it immediately spat out large patches of viscous green liquid from its annular mouthparts, all over the stone slabs shrouded in poisonous mist, forming patches of tumbling and bubbling poisonous pools.

And the combination of the two seems to have changed somewhat.

"Whew!"

The troll who had stepped on the poison pool first suddenly let out an inhuman scream.

It was seen that its body started from the soles of its feet, and suddenly erupted into terrible lesions, as if the flesh and blood tissue in its body was corrupted, forming swelling, and the skin on the surface of the body was infected and ulcerated, and a malignant abscess grew.

In just three seconds, the troll was incapacitated and turned into a lump of rotten flesh that only screamed when it was limp on the ground!

"Oh! Oh! ”

The other trolls who had already given birth to wisdom were frightened when they saw this scene.

Even the fanatical troll showed fear.

But obviously,

It was not the power of the foul cyst that terrified it, but the two abyssal blightworms that brought back some terrible memories of it.

"Camosa!"

It soon let out a stern roar, as if urging the other trolls to move on, and the remaining trolls finally took a bold step forward under the threat of its dangling giant chainsaw.

"Whew!"

There are constantly trolls affected by foul-smelling cysts, which decay and fester.

But gradually,

This only stimulates the ferocity that is buried in their bones.

Cheng Shen soon saw the murderous scene.

Those trolls who were blinded by the poisonous mist and ran backwards were directly smashed into pulp by the other trolls who caught up.

In order to get out of this area of terror ravaged by the double plague as soon as possible.

They don't even hesitate to kill their own people in their way!

Scold!

A loud chirp rang out.

Boundless fiery red clouds began to converge in the sky.

It's another wave of monsters.

Wings of Flame.

In the face of this double sense of oppression.

Cheng Shen couldn't help but feel a little suffocated.

For the first time, he became suspicious.

Can these towers alone really hold off the fifth wave of monsters?!
