"It is guaranteed that the output reaches more than 30,000 within 30 seconds......"

"Nope."

"The control effect of ordinary monster eating, with the combination of the Ice Arrow Tower and the Water Demon Tower, can greatly reduce the demand for output strength."

Cheng Shen pondered.

He learned an important piece of information from Aoki's mouth, the second wave of monsters would not refresh until six hours later, and he had enough time to prepare.

Upgrade!

Cheng Shen consumed 150 wood and 9 gold coins to smash the Wooden Arrow Tower to level nine.

At level 10, the material requirements increase again.

50 units of wood and 50 units of stone.

Plus an energy stone.

Energy stone is a high-grade material, and it is also needed to upgrade the energy tower, but Cheng Shen only found three pieces in the entire market.

One is used to upgrade the Wooden Arrow Tower.

After the Wooden Arrow Tower was upgraded to the full level, its attributes ushered in another qualitative change.

【Multiple Wooden Arrow Towers】

【Basic】

[Level: Normal]

[Grade: MAX]

[Attack: 120]

[Attack Speed: 1.0]

[Range: 90]

[Characteristics: When attacking, three wooden arrows can be shot at the same time, with a 15% chance of triggering multiple effects, and five wooden arrows can be shot at the same time]

[Durability value: 1000/1000]

……

Max Tier Wooden Arrow Tower's base attack increased from 80 to 120.

Double shooting becomes multiple shooting.

But if you want to talk about the strongest increase, Cheng Shen believes that it is still an increase in attack speed, shortened from 1.2 to 1.0, reaching a real shot per second!

Its base DPS has reached 360 points.

It's an epic enhancement.

It is worthy of the king of cost performance!

Cheng Shen then used up the remaining two energy stones to upgrade the Gathering Tower to Level 3, perhaps because the effect of the Gathering Tower was already very strong, and its improvement was not obvious, only adding the duration of the 2-second burst state.

But that's its most important attribute.

Upgrading the Lightning Tower requires copper ingots.

It takes 10 units to upgrade one level.

Cheng Shen swept away all the low-priced copper ingots on the market, and added the original inventory to make up a total of 66 pieces.

Just enough to get to level six.

【Lightning Tower】

【Element】

[Grade: Excellent]

[Level: 6]

[Attack: 80]

[Attack Speed: 1.5]

[Range: 75]

[Characteristics: Each lightning bolt can be bounced four times in a row between similar targets, -20% damage per projectile, and the number of lightning bounces is doubled when it comes into contact with stagnant water, and it is no longer limited by the effect of decreasing damage]

[Durability value: 1000/1000]

……

The attributes of the lightning tower have also ushered in a leap forward.

Of course, for the Lightning Tower, the number of bounces increased is actually secondary, mainly the increase in the base attack.

The foundation went up.

Naturally, the output efficiency increases.

"Almost."

Cheng Shen said in his heart.

The money is almost spent.

One hundred gold coins is indeed a lot, but no amount of money can withstand his consumption at such a cost.

First, it cost 11 gold to trade with Aoki, 14 gold to upgrade the Wooden Arrow Tower, and the upgrade of the two towers of the Energy Tower and the Lightning Tower is even bigger, requiring 5 gold at a time, plus the purchase of materials, a total of 86 gold has been smashed.

It is best to describe it as spending money like running water.

But Cheng Shen was not distressed.

Money is only valuable if it is spent, and if it is hoarded in your hands, it will not have any effect, even if it is piled up in a room, it is worthless.

He doesn't have any quirks of swimming in a sea of gold coins.

There are also 14 gold.

Cheng Shen is going to use it to upgrade the territory facilities.

First of all.

Upgrade the wooden fence to the second level.

Although he had decided to brush up on his S-Class No Injury Score, his cautious nature had made him accustomed to preparing for everything.

Level 2 Wooden Fence Defense has been increased.

Durability is now 10,000.

9 gold remaining.

Cheng Shen spent hardware to upgrade the training stake to the second level.

【Training Stakes】

【First Order】

[Level: Normal]

[Level: 2]

[Effect: Each attack on the stake grants 2 Attack Proficiency / 2 Skill Proficiency]

[Characteristic: None]

[Durability: 500/500]

……

Training stakes is very important for his personal development.

But for now, defending the territory still has to rely on towers.

Cheng Shen knows what to prioritize.

So not too many resources are tilted towards it.

With some materials in his hand, Cheng Shen suddenly noticed the bucket and rope stored in the backpack, and then remembered that the well could be repaired.

Immediately.

Throw in 10 units of stone and 10 units of wood, and the moss-covered wellhead suddenly takes on a new look.

【Well】

【First Order】

[Level: Normal]

[Level: 1]

[Effect: A wellhead that leads to nowhere, the bottom of the well is full of dangers and unknown things, in fact, its appearance is a decoration, as long as it stands still, it can produce 5 units of clean water per hour]

[Characteristic: None]

[Durability: 1000/1000]

……

"Huh?"

The effect of the well is a bit special, which attracted Cheng Shen's attention.

He couldn't help but be curious, came to the well, and looked down, but he could only see a dark darkness, bottomless, like... A mouthful of the abyss.

Whoa......

Suddenly, he heard the faint sound of water.

Cheng Shen didn't care at first.

But soon, he sensed that something was wrong.

If there was a dark river flowing at the bottom of the well, why didn't he hear it when he approached it at first?

Moreover, the voice seemed to be getting closer and closer to him......

Suddenly,

A grim white appeared at the bottom of the well.

Cheng Shen stared intently.

When I saw the appearance of that thing, I was shocked.

It was a female corpse.

Her back was up, floating in the water, her body was swollen and white, her clothes were tattered, her black hair was tangled like aquatic plants, and a stream of black water was constantly surging under her, pushing her up slowly.

The cold spreads.

A layer of frost formed on the walls of the smooth well at a rate visible to the naked eye.

A thick smell of decay poured into the well.

"Woo ......"

Cheng Shen even faintly heard a burst of sorrow, which made his heart furious.

What is this......

A very ominous premonition rose in his heart.

Hurry back.

But the strange changes in the well didn't stop there.

Immediately, wisps of black smoke condensed like substance continued to drift outward from the well's mouth, and the deep frost soon spread to the ground near the well.

The black smoke that rose was like a dark cloud hanging over the territory.

The surrounding light dimmed in an instant.

Whoa!

The sound of the water is getting closer and closer, and Cheng Shen has withdrawn more than ten meters away, and he can still hear it clearly.

No.

More than just hearing.

He saw that streams of black liquid had already overflowed from the wellhead, and half of his swollen and white arm stretched out from the side of the well......

The stuff in the well wants to climb out!

Cheng Shen was shocked.

He had a hunch that what was in the well was not something he could deal with right now. Once you let it get out, there is only a dead end waiting for you!

Towers, Attack!

Airplanes!

The power of the Gathering Tower increased to the maximum in an instant, and a clear blue aura was directly set on the Ice Arrow Tower.

The four defense towers were in full fire in an instant, however, the thin layer of black water that overflowed from the well was like an unfathomable ocean, swallowing up all the attacks, and the attack of the defense towers did not have any effect at all.

At this time.

The floating corpse in the well has already exposed its entire back!
