Looking at the construction drawings in his hand, Ren Qi was stunned.

It turned out to be an advanced construction drawing!

And this dark crystal tower suits his military type very well.

The succubus itself is of the dark type. If this dark crystal tower is built, the experience of the unit can be increased within 100 meters of it.

Ten experience points per hour is almost equivalent to half a kilogram of second-level demon meat.

The most important thing is that it doesn't have to be as complicated as digesting demonic flesh. It can be improved as long as it is within a hundred meters of the crystal tower.

This is what makes Ren Qi's heart move the most.

And the second effect is also very good, it can increase the defense and attack power of the surrounding dark-type troops within 100 meters.

Although it is only 10%, it is still a very good bonus.

It's just that the range is a bit short, only a hundred meters.

With the expansion of the territory, this effect will definitely not cover the surrounding areas of the territory.

But what Ren Qi mainly wants now is not the second effect, but the first effect.

Building this dark crystal tower around where the succubi live can improve their experience all the time. Although this process is relatively slow, it is also an unexpected blessing.

However, the conditions required to build this dark crystal tower are still relatively harsh.

Wood, stone and the like are relatively simple, but refined iron costs three thousand kilograms, and energy crystals also require a hundred.

Although Ren Qi's energy crystals are now abundant, refined iron is indeed relatively scarce.

After the fine iron wall is built, there is not much left.

However, Ren Qi was not in a hurry. The construction of the Dark Crystal Tower could be left until after the demonic tide.

After thinking about it, Ren Qi posted a transaction information to the chat group.

[Tomorrow at 6 o'clock in the evening, I will sell ten Tier 4 defense towers here, the quantity is limited, first come first served. 】

[This time, the fourth-level defense tower only exchanges for four things, which are high-level magic meat of level six and above, refined iron and energy crystals, and finally magic crystals.]

[Magic crystals can be exchanged first. Four magic crystals can be exchanged for a fourth-level defense tower. The exchange ratios for the other three items will be announced in due course. 】

As soon as this news was posted to the chat group, it immediately sparked a huge discussion.

After all, Ren Qi had already announced it before, and everyone was waiting for news about the fourth-level defense tower.

For these new lords, the fourth-level defense tower can even determine whether they can survive the first wave of magic.

[Big Brother Qiqiqi’s fourth-level defense tower is finally out, but the materials in exchange are a bit harsh. Except for refined iron and energy crystals, which are resources I can collect, I don’t have the other two at all. 】

[Yes, if I can kill the sixth-level monsters, I won’t need this fourth-level defense tower. 】

[The number of magic crystals is so rare that only one magic crystal was awarded to the top ten in each major region during the assessment.]

For most of the new lords, although they are now able to hunt monsters, most of them can only hunt monsters below the fourth level.

After all, even some lords who have awakened their sixth- and seventh-level arms are still unable to hunt monsters above the sixth level before their arms reach level 50 adults.

Currently, the only people who can hunt monsters above level 6 are probably lords who have awakened super-advanced arms such as level 8.

As for magic crystals, they are even rarer. After all, magic crystals are a necessary item for the upgrade recruitment pool.

After many new lords possess magic crystals, they will immediately choose to upgrade the recruitment pool to increase the number of troops they can recruit.

Most of these magic crystals were brought in before the territory materialized. After all, although the probability of monsters here exploding magic crystals is many times higher than outside, they must be elite-level monsters above the fourth level to be able to do so.

There is a chance of finding magic crystals in the body.

For many new lords, magic crystals are something out of reach.

At least it is unlikely for them to have it now.

Of course, some new lords who were brought in from outside and whose magic crystals have not yet been used are thinking about whether to use magic crystals in exchange for fourth-level defense towers.

Magic crystals can upgrade the recruitment pool and increase the potential of territory development.

But the fourth-level defense tower may become the key to defending against the demonic tide, which makes some people undecided.

[By the way, the best app for reading and listening to books is Yeguo Reading, www. Install the latest version. 】

But there is still one day left for them to think about it.

[It seems that we will be mining refined iron soon. Fortunately, I have a refined iron mine here. I hope that the price offered by Mr. Qiqiqi will not be too outrageous.]

[I do have some sixth-level high-grade magic meat here, but not much. I don’t know how much Big Brother Qiqiqi needs to exchange for it.]

[I really envy Mr. Qiqiqi, but at this time, there are already so many supplies available for sale. ]

[Big Brother Qiqiqi’s territory is developing so fast that we can’t even catch up.]

The chat group was in full swing, some were happy and some were sad.

With the announcement of Ren Qi's request, the prices of fine iron and high-level demon meat increased dramatically. Those lords who did not need the fourth-level defense towers sold a batch of high-level demon meat and made a lot of money from it.

Ren Qi looked at the information in the chat group and nodded slightly.

This is the effect he wants. Except for the magic crystals exchanged for them, Ren Qi is planning to sell all the fourth-level defense towers at auction tomorrow.

It will be given to whoever offers the higher price.

After thinking about it, Ren Qi posted another transaction information.

[Ten energy crystals in exchange for 10,000 kilograms of gunpowder, come quickly!]

Gunpowder is no stranger to the new lords. The knowledge they have learned before is about the production of gunpowder.

As long as there are relevant materials around the territory, it can be produced.

And some lords who have awakened the mechanical arms have prepared a lot in advance. Ten energy crystals can be exchanged for 10,000 kilograms of gunpowder. The price is still very affordable.

Soon, someone contacted Ren Qi and directly traded 10,000 kilograms of gunpowder.

Ren Qi sent several succubi to the exchange to conduct transactions, and then delivered the gunpowder to Luo Ming.

With these gunpowders and Luo Ming's artillery construction drawings, we should be able to ensure safety in this demonic tide.

After finishing all the things, the sky gradually darkened.

The succubi also ended their day's hunting. In addition to the giant lizard group, they also harvested a lot of third-level demon meat today.

Ren Qi now has a lot of demonic meat stored, but there is still some shortage of high-level demonic meat, which will be auctioned tomorrow.

All the succubi began to rest and eat demon meat, and Elise and Maggie also began to count the succubi.

This is something that must be done every day.

After all, when hunting in the jungle, they need to send a lot of succubus to explore the surrounding jungle, firstly to detect the situation, and secondly to avoid any danger and provide early warning.

These succubi sent out serve as scouts for the entire succubus army.

In the past, even if the Succubus Legion suffered some casualties, there were still quite a few casualties.

But today when we counted the succubus army, one was missing.
