The fortress cannot be upgraded for the time being because it requires too many resources. Upgrading from level 2 to level 3 requires 3,000 units of bones and units of soul energy. The key point is that it is not that useful.
Let's build some other buildings first and see if we can get some more powerful troops. Even though the undead are a race that wins by numbers, they can't be without any high-level combat power.
After searching around, I noticed two buildings that I had previously overlooked - the Alien Tomb and the Tattoo Workshop.
These two buildings are hidden buildings unlocked after decomposing the demonized Minotaur. At that time, Li Ziyu forgot about them because of insufficient resources.
【Alien Tomb】
[Introduction: With this building, you can summon all kinds of strange and special undead]
[Construction Requirements: Skeletons*100 units, Stone*5 units, Wood*5 units, Soul Energy*100 units, Mutated Soul Energy*100 units]
【Occupied area: 10 units】
Damn, another cute introduction from the system. I hope this special undead can bring me some surprises.
Li Ziyu sighed, chose to build the alien tomb, and then turned his attention to the tattoo workshop.
【Printing Workshop】
[Introduction: A tattoo parlor run by the Undead. However, tattoos aren't just for looks; they also grant power and strange abilities.]
[Construction requirements: Skeleton*10 units, Soul Energy*10 units]
【Area: 4 units】
Li Ziyu's mouth twitched as he watched the introduction, with a frown on his face. Let's just say, can't you be more serious when introducing the architecture? What's the big deal about having a seizure from time to time? If you want to enchant it, you can enchant it, but you have to open a tattoo shop, what the hell is a tattoo shop!
No matter how much you complain about the system, it still has to be built.
After choosing to build, a construction site scene suddenly appeared on the platform. It was the construction site of the Undead. There was no bustling and dusty scene like when humans built houses. It was just the process of countless bones moving, splicing each other, and reintegrating.
The Minotaur, who had eaten and drunk his fill and was digesting his food, heard the noise and, driven by curiosity, came over. He looked at the construction site in amazement, clicking his tongue in wonder.
It would take some time to build the two buildings, and the results would not be seen until tomorrow at the latest. Li Ziyu ignored it and continued to study how to upgrade the technology.
Upgrading military technology is the most practical and orthodox way for the Undead to upgrade.
He researched a small bone knife in the weapons workshop and a small round shield in the armor workshop, which allowed him to unlock the first undead soldier, the skeleton warrior. If he wanted to unlock other soldiers, he would need to research more technology.
Thinking about the undead's fighting mode, it is that they are not afraid of death and attack fiercely. Even if they are broken into pieces, they can be put back together. The only weakness is the soul fire in the skull.
Hmm, so should I increase my attack power or my defense power?
Li Ziyu touched his chin and felt that he still needed to improve his defense. At least he had to protect his head. This way, his survival rate would be further improved and he would be much more stable.
As the saying goes, as long as you can't kill me, I can always grind you down to death. With five tanks in the ranking, I can push your middle lane.
He opened the armor workshop, searched inside, and actually found the helmet.
Round Helmet (Bone): The most basic helmet. Not only does it properly protect your fragile skull, but it also allows the undead to headbutt you with impunity. This simple and practical helmet is also affectionately called a coconut shell helmet or a watermelon rind helmet.
[R&D requirements: Soul energy*50 units]
The picture given by the system looks like an uncovered rider's helmet, which is round. No wonder it is criticized as a coconut shell helmet. It really looks like that.
This thing only costs 50 units of soul energy, no problem, unlocked.
As soon as I unlocked the helmet, a system prompt popped up.
[Warrior Training Camp-Intermediate Skeleton Warrior Unlock]
No, is it so easy to unlock the intermediate skeleton warrior? If you had told me earlier, I would have unlocked the helmet long ago. Li Ziyu patted his forehead.
Everything else about the system is good except that a lot of key information is hidden and needs to be dug out by yourself. You also don't know what you did unintentionally that would trigger hidden buildings or arms. It's just like the easter eggs in many single-player games in the past. It's completely the designer's bad taste.
Maybe some people like to find Easter eggs in the game, but Li Ziyu is very annoyed by this feeling. He likes to be clear and understand everything.
The cost of a helmet is much more expensive than a bone knife and a round shield, and one unit of bones can only make two helmets.
The requirements for intermediate skeleton warriors in the warrior training camp have become [small bone knife, small round shield (bone shield), round helmet (bone), soul energy * 100 units]. Compared to before, it is just a simple addition of a helmet.
Um……
Li Ziyu was silent, Li Ziyu seemed to be thinking about something, and then Li Ziyu suddenly realized.
Damn it, based on this situation and the nature of the system, the high-level skeleton warrior is... He hurriedly searched in the armor workshop.
[Simple Bone Armor: This thing is just bone on top of bone. It has some defensive power, but don't expect it to be that strong. Just think of it as two skeletons stacked together. Oh, and by the way, the bone armor has the same properties as the undead, so don't worry about it falling apart. As long as it's not completely broken, it will heal itself after a while.]
[R&D requirements: Soul energy*500 units]
500 units of soul energy? !
The previous bone knife was 30 units, the round shield was also 30 units, the helmet I just researched was 50 units, and the armor was actually 500 units. It's so expensive!
If Li Ziyu had not fought with the lizardmen before and his soul energy had not experienced an explosive growth, he would not have dared to study it casually.
After the simple bone armor was unlocked, the system prompt followed: [Warrior Training Camp - Advanced Skeleton Warrior Unlocked].
I guessed it right. As expected, the system is like this. If you equip all four sets, you can unlock high-level warriors.
I just don't know how strong this high-level skeleton warrior is compared to the low-level skeleton warriors.
After looking at the cost of the simple skeleton, I couldn't help but take a breath. Wow, it takes 5 skeletons to make one set. Not only does the armor require a lot of soul energy to unlock, it is also expensive. It is really not something that can be mass-produced.
The simple skeleton shown in the system image is a set of armor with only the upper body. It is cylindrical in shape, with two thick spine-like bones in the middle, and rib-like, slightly thinner curved bones connected on both sides. Looking at the appearance of this armor, it is not accurate to say that it is simple, and it is more appropriate to say that it is crude.
To be honest, this kind of armor is only useful for the undead. If a normal person wears it, he will definitely be stabbed to death. The gap between the two ribs is so big that you can almost put a fist in it.
Anyway, no matter whether it looks good or ugly, practicality is the most important thing. Let’s first see the effect of 10 high-level skeleton warriors.
It is true that he gained a lot during this period. First, he defeated a wave of lizardmen, and then encountered the swamp cemetery. Otherwise, even if Li Ziyu unlocked the advanced skeleton warrior, he would not be able to create it.
