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

It was actually a high-level construction blueprint!

Moreover, this Dark Crystal Tower was very suitable for his troops.

The succubus itself was a dark-type unit. If this Dark Crystal Tower was built, it could increase the experience points of the troops within a hundred meters.

Ten experience points per hour was equivalent to half a kilogram of Tier 2 demon meat.

Most importantly, there was no need to digest the demonic meat. As long as the unit was within 100 meters of the crystal tower, it could be improved.

This was what Ren Qi was most excited about.

Moreover, the second effect was also very good. It could increase the defense and attack power of the dark troops within 100 meters.

Although it was only 10% , it was still a pretty good bonus.

However, the range was a little short, only 100 meters.

With the expansion of the territory, this effect would definitely not be able to cover the area around the territory.

However, Ren Qi did not want the second effect. Instead, he wanted the first effect.

By building this Dark Crystal Tower around the succubus’ residence, it would be able to increase their experience at all times. Although the process was relatively slow, it was still a pleasant surprise.

However, the requirements for building the Dark Crystal Tower were still quite harsh.

Wood, stone, and the like were relatively simple, but it required 3000 kilograms of refined iron and also 100 energy crystals.

Although Ren Qi had sufficient energy crystals, refined iron was indeed scarce.

After building the refined iron wall, there wasn’t much left.

However, Ren Qi wasn’t in a hurry. The matter of building the Dark Crystal Tower could be left until after the demon wave.

After thinking for a moment, Ren Qi posted a trade message in the chat group.

[ Tomorrow at 6 pm, I’ll be selling 10 Tier-4 defense towers. The number is limited. First come, first served ]

[ This time, the Tier 4 defense towers will only be exchanged for four things: high-level demonic meat above tier 6, refined iron, energy crystals, and finally, magic crystals ]

[ Magic crystals will be prioritised first. Four magic crystals for a Tier 4 defense tower. The exchange rate for the other three items will be announced later. ]

The moment this news was posted in the chat group, it instantly stirred up a huge discussion.

After all, Ren Qi had already announced before that everyone should wait for the news of the Tier 4 defense tower.

To these new lords, the Tier 4 defense tower could even decide whether they could survive the first wave of the demon wave.

[ The Tier 4 defense tower of Boss 777 has finally come out. However, the exchange rate for it is a little harsh. Apart from refined iron and energy crystals, which are the resources I can collect, I don’t have the other two. ]

[ Yeah. If I could kill Tier 6 monsters, I wouldn’t need the Tier 4 defense tower. ]

[ The number of magic crystals is too low. The top 10 of each region were only rewarded one magic crystal during the assessment. ]

For most of the new lords, although they could already hunt monsters, most of them could only hunt monsters below Tier 4.

After all, even some lords who had awakened a Tier 6 or Tier 7 soldier would not be able to hunt monsters above Tier 6 before their troops reached adulthood at level 50.

Currently, only lords who had awakened a super high-tier soldier like a Tier 8 unit could hunt monsters above Tier 6.

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

Most new lords who had a magic crystal would choose to upgrade the recruitment pool as soon as possible to increase the number of soldiers they could recruit.

Most of these magic crystals were brought in before the territory materialized. After all, although the chances of magic crystals dropping from monsters here were many times higher than outside, they had to be atleast elite monsters above Tier 4. Only then would there be a chance to find magic crystals in their bodies.

For many new lords, magic crystals were something that they could not hope to obtain.

At least, it was unlikely for them to possess them now.

Of course, some new lords who had brought in magic crystals but had yet to use them were considering whether they should use magic crystals to exchange for a Tier 4 defense tower.

Magic crystals could be used to upgrade the recruitment pool and increase the development potential of the territory.

However, the Tier 4 defense tower might become the key to defending against the demon wave this time. This made some people uncertain.

However, there was still one more day. They could think about it carefully.

[ It seems that we need to quickly mine refined iron. Fortunately, I have a refined iron mine here. I hope that the price offered by 777 will not be too outrageous. ]

[ I do have some Tier 6 demonic meat, but I don’t know how much 777 needs to exchange for it. ]

[ I really envy 777. They already have so many resources to sell at this time. ]

[ The development speed of 77’s territory is really fast. It’s far beyond our reach. ]

The chat group was bustling with activity. Some people were happy while others were worried.

Following Ren Qi’s announcement, the prices of refined iron and high-tier demon meat skyrocketed. Those lords who didn’t need the Tier 4 defense towers sold a batch of high-tier demonic meat, profiting greatly from it.

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

This was the effect he wanted. Besides the towers he would exchange for with magic crystals, Ren Qi planned to auction off all the Tier 4 defense towers the next day.

He would sell them to the highest bidder.

After giving it some thought, Ren Qi sent out another trade message.

[ 10 energy crystals in exchange for 10,000 kilograms of gunpowder. Come quickly! ]

Gunpowder was not unfamiliar to the new lords. The knowledge they had learned before taught them how to the manufacture gunpowder.

As long as there were relevant materials around the territory, they could manufacture it.

Some lords who had awakened the mechanical army even prepared a lot in advance. Ten energy crystals in exchange for 10,000 kilograms of gunpowder. This price was still very affordable.

Very quickly, someone contacted Ren Qi and directly traded over 10,000 kilograms of gunpowder.

Ren Qi sent a few succubi to the passage to carry out the trade and deliver the gunpowder to Luo Ming.

With this gunpowder and Luo Ming’s cannon blueprint, they should be able to guarantee their safety in this demon wave.

After settling everything, the sky gradually darkened.

The succubi also finished their day’s hunting. Apart from the giant lizards, they also harvested a lot of Tier 3 demonic meat today.

Ren Qi already had a lot of demonic meat in storage, but there was still a lack of high-tier demonic meat. He was just waiting for the auction tomorrow.

All the succubi began to rest and eat demonic meat, while Elise and Maggie began to count the succubi.

This was something that they had to do every day.

After all, when they were hunting in the forest, they had to send out many succubi to explore the surroundings of the forest. Firstly, it was to investigate the situation, and secondly, it was to avoid any danger and provide early warning.

These succubi were sent out to act as scouts for the entire succubus army.

Previously, even if there were some injured soldiers in the succubi army, there were all accounted for.

But in today’s count, there was actually one less succubus.

After Elise carefully checked again, she discovered that the one who was missing was Risa.
