There are many items traded in the market.

But when it comes to towers, most people still just trade them for them.

There are no fools who can survive the first wave, they have seen the fierce monsters attacking the city, and everyone wants to build two more towers to strengthen the defense of the territory.

And in contrast.

Recruitment papers, which are as precious as making pictures, have become cheaper.

This is obvious, and it can be seen from Cheng Shen's own situation.

In the first wave of defense, 90% of the output was played by the Ice Arrow Tower.

9% of the output is his contribution.

Soul Eaters can only make up 1%.

At the same level, the combat effectiveness of recruited units and towers is simply not comparable.

Of course, this does not mean that the recruiting unit is completely useless.

Cheng Shen guessed that the recruiting unit should be prepared for players to develop to the middle and late stages and explore outward.

Again.

The production unit is also more important in the early stage.

He watched the World Channel, and someone recruited a rare production unit, Life Spirit, which can produce fruit or collect wood.

Equivalent to a walking resource pack.

He really couldn't envy that kind of luck.

"Void Slate...... Hey? ”

Cheng Shen suddenly found something interesting.

This slate has only one property:

Guide monsters to move.

Place stone slabs and pave paths to guide monsters along the path without running around.

But there is a premise.

The two ends of the road must be connected to the main gate of the territory and the gate of chaos.

The Gate of Chaos is the equivalent of a strange mouth.

To build the Gate of Chaos, not only did you need nine Void Stone Tablets, but you also had to use something called the Chaos Hub.

The size of a Void Slab is 1 square meter.

In other words, it is not enough to rely on these ten Void Slabs to build a fixed spawn route.

The range of the Ice Arrow Tower alone was 105 meters, and if he wanted to build a monster farm, he would have to be at least 100 meters away.

It would also require at least 110 Void Slabs and a Chaos Hub.

But

This stuff is still very useful.

Cheng Shen is still unable to determine the location of the system's monster farming, whether it is fixed or random.

If you can't keep it together, one day the system will directly brush the monster to his door.

Give him a big surprise.

And with the Void Slate, there is no need to worry about this kind of problem again.

"Two pieces of 1 gold coin...... It's a little expensive, but I don't know what the explosion rate is, and when everyone realizes the importance of this thing, I'm afraid the price will have to go up, after all, the demand is large, and everyone uses it..."

Cheng Shen pondered.

In the end, he still didn't buy it, and was ready to wait and see first, and then another, and the void slabs in the market now didn't add up enough for him to build a road.

"The Green Auxiliary Tower, the Spider Silk Tower, will be replaced by an Elemental Output Tower."

"3 iron ingots for an iron bucket."

"Bread for rope."

Cheng Shen put all the three items he needed on the trading market.

While waiting, he opened the list of the construction of the realm.

Cheng Shen, who was about to start building a defense tower, suddenly saw a special description in the territory resource column.

【Fire Demon Lizard 23 (Unprocessed)】

……

The corpses of the first wave of monsters?

Cheng Shen slapped his thigh violently.

Yes, he was limited by the experience of the game, and subconsciously ignored that this was a real world.

Monster corpses are not spawned.

Imply.

In addition to system rewards, he can also scavenge resources from attacking monsters!

Cheng Shen immediately walked out of the territory and saw that the soul devouring insect that had recovered its body was lying on the corpse of a fire demon lizard, it opened its hideous mouthparts and swallowed half of it, and its eyes were strangely round.

"Hey, you useless guy, you're pretty positive!"

He groaned.

casually opened the attribute interface of the Soul Eater and took a look.

After a defensive battle, its level has also successfully broken through Level 2.

However, its source of experience is mainly through the devouring of corpses.

Cheng Shen found out before.

When defending towers to kill monsters, the experience of a monster will be divided equally among all units in the territory.

And in his territory, it was only him and the Spirit Eater.

Therefore, he can only eat 5 experience points for the Fire Demon Lizard killed by the Ice Arrow Tower, and the unit he killed with his own hands is 10 points in full.

The next wave of monsters was killed by him himself.

It stands to reason that

He should be more level than the Soul Eater.

But in fact, having devoured the corpses of seven Fire Demon Lizards, it was now on the verge of breaking through to the third level.

Although it still didn't work.

"Gollum ......"

The Spirit Eater seemed to understand his words and made a grieved sound.

But it can't be reminiscent of cuteness......

Do you want to collect the current target? 】

[Your collection level is: 1, the harvest rate: 38%, and the corpse of the unit will disappear completely after collection!] 】

……

Cheng Shen heard a hint after touching the corpse of a fire demon lizard.

"Gathering."

He gave instructions.

Swish!

A ray of light shot out, slowly decomposing the corpses on the ground.

[Obtain: Demon Scales +6!] 】

[Gain: Raw Meat +3!] 】

[Gathering Proficiency +1!] 】

……

The two materials appeared directly in Cheng Shen's backpack.

There is meat!

He was overjoyed.

At this stage, even bread is considered a scarce resource, and it is in short supply in the trading market.

Meat is even more precious.

Cheng Shen decisively decomposed all the remaining corpses.

Although his collection level is not high, and the utilization rate of corpses is low, it is better than feeding the Soul Eater, a money-losing goods that has no entry or exit...

[Obtain: Demon Scales +131!] 】

[Obtain: Raw Meat +62!] 】

……

Demonic scales are a material used to forge equipment.

He doesn't need it yet.

I thought about it.

Cheng Shen took out ten scales and threw them on the trading market, with a price tag of 1 gold.

People in need will naturally take the initiative to find him.

Looking at the pile of raw meat in the backpack, Cheng Shen pondered in his heart that the ice cellar had to be dug out as soon as possible.

He then opened the list of provinces.

Wooden Arrow Tower, Build!

Gathering Tower, Build!

Wooden fence, fixed!

After the wooden fence was repaired and repaired, Cheng Shen decisively put all the remaining wood into the upgrading of the wooden arrow tower.

Upgrading the Arrow Tower requires 20 units of wood and 2 gold coins.

Cheng Shen was directly promoted to five levels in a row.

【Double Wooden Arrow Tower】

【Basic】

[Level: Normal]

[Level: 6]

[Attack: 80]

[Attack Speed: 1.2]

[Range: 90]

[Feature: Each attack can shoot two wooden arrows at the same time]

[Durability: 1200/1200]

……

After level six, the Wooden Arrow Tower underwent a qualitative change and evolved into a double Wooden Arrow Tower, doubling its output efficiency.

That's more than the combined output of two Rare towers.

It is worthy of the king of cost performance.

You must know that the Wooden Arrow Tower, which is upgraded to level six, consumes less resources than the Ice Arrow Tower.

[There are new changes to your trading information!] 】

A system prompt is coming.

Cheng Shen entered the market.

Unexpectedly, the two transactions of the iron bucket and the rope were completed smoothly, and seven or eight lords of the Spider Silk Tower made exchange requests.

Several of them wanted to exchange for white output towers.

He ignored him outright.

The rest of the people all came up with something more sincere:
