The first batch of ghost dragon knights produced, Du You directly sent all of them to the front line. Although his own strength on the front line is strong, after the last battle, he was also targeted by the demons.

If you don't strengthen your strength, there is a high chance that you will be attacked. Even if you strengthen it, as long as you don't go too far, it's okay. After all, it was not easy for the abyss to let go of some high-level demons.

There are still a lot of fifth-order demons, but there are a lot of sixth-order ones.

At the same time, Du You also discovered that the Ghost Guardian was actually able to control more than just armor. Because he has sent all the ghost guards to the battlefield, actual combat is the best way to test the combat effectiveness of the troops.

Of course, Du You still wants to use some demonic armor to offset the expenses on his side.

It's just that what Du You didn't expect was that these ghost knights could actually use dead demons as armor and wear them on their bodies. When it is put on, the demon will slowly turn into an undead creature, and the corpse cannot be used for other purposes. But if the corpse of a demon is not broken, it can hold out for more than ten years.

The sixth-order demons on the chaotic battlefield may not be easy to find, but there are too many fifth-order ones, one by one.

At the same time, the upgrade of troops and buildings on Du You's side is also in full swing.

Mage Tower Outbuildings:

Lich Hall: Can train a lich with the same level as a territory, 100 per month, no crystalline cost.

Skeleton Summoner Level 48: 400 per month, 150 Aquamarine Coins

The first is the revamp of the Lich Hall, adding the Skeleton Summoner class. Although the lich can also summon skeletons and zombies, it is an amateur, and the level of summoning is too poor, it does not meet Du You's requirements, and it is too wasteful of corpses.

And the skeleton summoner is professional in summoning skeletons, the skeleton level is high, and the quality is also good. The most important thing is that under the control of the Skeleton Summoner, the combat effectiveness of the skeleton soldiers will be significantly improved.

It's cheap, maybe because the Skeleton Summoner itself isn't very strong, but that's enough. Prepare more skeletons and sacrifice them when you return.

Bone Wall (6th Order): Defense 60+60+60, Magic Resistance 60+60+60, contains a spell barrier, and the wall and the area protected by the wall are not attacked until the spell barrier is shattered.

Function: The Bone Wall can automatically condense bone arrows to attack the enemy, with an attack strength of 56 and soul damage. Bone undead can be fused to the Bone Wall to exert a defensive attack effect. The undead of their own bones can freely enter and exit the city wall, and the wall will not block it.

After the infusion of a large number of high-level undead bones, as well as the integration of some special treasures, the level of his own bone wall increased. Defense and magic resistance have been increased by one level, as has the attack strength of bone arrows.

Of course, there is only one section of such a city wall, but after having this section, Du You will be able to get the sixth-order city wall drawings if he takes it back and studies it in the civilian research laboratory. At that time, it was possible to manufacture it in large quantities.

It's a bit wrong to use a civilian research lab to study the city walls, but it can still be done by spending a little more crystals.

Sea of Bones (4th Order):

30,000 first-order skeletons, 3,000 second-order skeletons, 300 third-order skeletons, and 30 fourth-order skeletons are automatically formed every day.

Similarly, after the Sea of Bones, which was treated like a garbage treatment plant, was upgraded to the fourth order, the output of all the skeletons before was directly tripled, and at the same time, the number of fourth-order skeletons per day was increased by thirty, so that there were nine hundred skeletons per month.

In terms of the production of fourth-order skeletons, it is also quite good, although it is just some ordinary skeletons.

The best use for these skeletons is to train other fourth-order skeleton classes, which can keep the price down to the limit.

Ten Thousand Bone Pits (Fifth Order):

Sword and Shield Skeleton Level 45: 300 pieces/month, full price 150 Aquamarine Coins/piece

Skeleton Archer Level 45: 300 pieces/month, full price 150 Aquamarine Coins/piece

Death Guard Level 47: 100 pieces/month, full price 300 Blue Crystal Coins/piece

Chaos Bone Spider Level 46: 300 per month, full price of 150 Blue Crystal Coins/Stone

The level of the Ten Thousand Bone Pit has not been improved, it is still the fifth order, but the level of the troops has increased during this time. The Sword and Shield Skeleton and Skeleton Archer have been upgraded from the fourth order to the fifth order, and the corresponding number has decreased a lot, from five hundred to three hundred, but in terms of strength, it is much stronger than before.

In addition, the Chaos Bone Spider has also increased from level 35 to level 46, and its production has also dropped from 500 to 300. The newborn Chaos Bone Spider is much stronger than before in terms of strength, and of course it is mainly used to contain the enemy.

Mass grave (6th order):

Corpse Transporter Level 40: 700 units/month, full price 230 Citristine Coins/vehicle

Zombie Giant Level 52: 200 Monograms/Month, Full Price 300 Sombra Coins (+100%)

Half-Corpse Level 49: 200 pieces/month, full price 400 Aquamarine/piece (+100%)

Gravedigger Level 30: 5,000 pieces/month, full price of 100 Green Crystals/piece (+100%)

As the building that Du You focuses on improving, it is the mass grave, who makes the mass grave the largest output. After the mass grave was raised to the sixth order, the output in all aspects simply increased to a terrifying level. The double bonus is even more terrifying.

It's a pity that the troops in the mass grave are relatively special, and it is difficult for Du You to find the corresponding type outside to improve the level.

For example, corpse carriers and gravediggers rarely find naturally occurring undead creatures. Although there are now auto-generated ones in the territory, because of the rules, the level generated around your own territory is not high.

A few half-body corpses were found, but there were not enough of them, and there was no way to raise the level.

However, the zombie giant only needs giant zombies, Du You still found some, and directly raised it to level 52, adding a sixth-order class to the territory.

The sixth-order zombie giant has reached a height of more than five meters, which is already comparable to that of the Dragon Tomb Guardian.

Graveyard (Tier 6): Zombie outbuildings, increases the production of zombie types by 50%

Produce 10,000 third-order ordinary zombies per day.

The cemetery was used as an outbuilding, and Du You also raised it to the sixth order. The investment can be said to be very huge, but unfortunately I didn't get the results I wanted, and some of the gains outweighed the losses.

It's just that the third-order ordinary zombies created every day have changed from five thousand to ten thousand, and they are not of much use to the territory and themselves. I thought I could continue to increase the production bonus of zombie-type troops, but I really thought it was too good.

Perhaps the only good thing is that zombie dragons are now much faster to create than before, at least twice as fast. In the past, it may have been because the level of the bonus building could not keep up, so it slowed down in speed, Du You thought in his heart.
