The combat effectiveness of an undead army controlled by someone and an undead army controlled by no one can be said to be very different.

These skeletons and spirits that have emerged from the ground have always fought on their own, and they have only instinctively attacked Roy and them out of jealousy and resentment for the living, and such attacks can be said to be chaotic and non-threatening.

On the contrary, when Kassandra appeared, the part of the undead army under her control showed great combat effectiveness.

All the skeleton soldiers, arranged by her in a dense formation, firmly blocked in front, forming a of bones, so that those undead who came out of the ground again were smashed to pieces on this embankment wave after wave, under her control, their own skeletons can actually fight together, whenever an enemy rushes up, there are often three or five skeletons to meet them, with the old and rusty blades in their hands, to greet different places on the enemy's body, almost in the blink of an eye, you can chop the opponent into messy dry bones.

Although the skeleton soldiers, the lowest-level undead, the attack method is not surprising, but under the control of Kassandra, until all the skeletons that emerged from the ground were cleared, his own skeleton soldiers did not suffer much loss, such a result, so that Roy also had to admire, this kind of command art of the undead army, seems to be the natural instinct of the lich.

It wasn't until he was convinced that there were no more undead creatures that Roy said with satisfaction, "Let's go, get out of here!" ”

Everyone began to set off, but this time because of Kassandra and her undead army, Roy and the others no longer had to fly, everyone sat on the back of the fat tiger, and the fat tiger carried forward, and the skeletons and ghosts followed the fat tiger.

Needless to say, the skeleton soldiers themselves are only a skeleton, and of course they are very light, so although they are advancing on foot, the speed of the entire army is not slowing down.

Moreover, the undead creatures can not eat or drink, and they will not feel any fatigue, so in one night, Roy and they have to go out more than a hundred kilometers in the desert.

It's just that after dawn, they have to stop, the fear of the undead creatures of the sun will not change, it is impossible to let the troops advance in the sun, so Roy and they can only stop.

Roy originally wanted to create a frost fortress to block the sunlight, but in the desert environment, it took a lot of magic to do so, and in the end, Kassandra volunteered to use magic to create a dark canopy to block the sunlight and protect the undead troops.

Of course, after stopping, Roy and they didn't do nothing, Juliel and Fat Tiger each flew out in one direction, exploring the surroundings, a large number of undead appeared in the oasis before, which made Roy believe that there may be other places of death in this desert, although the number of skeleton soldiers controlled by Kassandra is large, but to be honest, these low-level undead alone do not have much combat power, Roy wants to find out if it is possible to find other high-level undead, so that Kassandra can control it.

Roy himself stayed where he was, the dark sky was a pitch-black smoke, in these smokes, the sun could not shine in, Roy also felt very comfortable, he also took advantage of this time, he also asked in detail how Kassandra lived after he left the Caribbean world.

As a result, I found out that Kassandra had been in the Caribbean world for more than 20 years!

"Master, I've been on the Frozen Island since you left!" Kassandra recounted: "According to the agreement between your master and the goddess of the sea, Tia Dolma, I cannot leave the island, but I have the right to deal with all the ships and sailors who have strayed into the frozen island at sea, and for more than twenty years I have lost count of how many people have broken into this island, and it is with the souls of these people that my magic has grown little by little to the point it is now." ”

Kassandra said it simply, but in fact, in the Caribbean world, the lich Kassandra wearing a robe, his reputation has spread all over the world, in addition, human rumors, the demon Osiris has been sleeping on the frozen island, the lich Kassandra is guarding the treasure of the dark and winter lord, the blessing of the doom gold passed down by Torroy, people believe that there is a lot of gold and wealth on the frozen island, this wealth is huge enough to buy the whole of England!

It is precisely because of this that the Frozen Island has gradually become a mythical place like the Fountain of Youth, although there are many people who have strayed into the Frozen Island because of the storm, but more of them are those greedy people who covet demonic wealth, among these people, there are pirates, adventurers, and the armies of colonial governors of various countries, although all those who arrived on the Frozen Island were eventually taken away by Kassandra and became irreversible, but such a forbidden place of death still can't stop the greedy nature of human beings, every year, Kassandra was able to harvest a lot of souls.

The soul is used to cultivate necromantic magic and increase magical power, and the remains are awakened to become an army of the undead, and Kassandra is not alone on the frozen island today, she controls a large number of undead troops, and even the crusading forces of the church have been repelled by her two or three waves......

Although there was an agreement with Roy, Tiathoma also had to make some restrictions on the frozen island, and now there are huge sea storms around the frozen island all year round, and the climate is indescribably harsh, and Tiathoma uses this method to restrict people from finding the frozen island as much as possible.

Of course, Kassandra would not mention these things to Roy, after all, there was a suspicion of showing off, but Roy still sensed some clues through questioning, he sensed Kassandra's current magic power, and found that Kassandra's current magic level was already at the level of the middle and upper level demons, and if she was given some time, she might be able to break through to the level of the upper demons.

At that time, Kassandra will become a Lich Master......

Of course, Roy is a demon, and the priority of the soul obtained is of course himself, and he can't give up too many souls for Kassandra to give her up, but this is the world of heroes and invincibles, necromancers are unique in this world, and there are many treasures created by necromancers in history, if Roy needs to improve Kassandra's strength and let her control as many undead troops as possible, it is the right choice to work on these undead treasures.

For example, the Necromancer Shield, the Skull Crown, the Boots of Death, the Staff of the Underworld, the Ring of No Remorse, the Cloak of Death and the like, as long as you can get similar treasures and arm Kassandra, you can also make her strong......

Juliel and Fat Tiger didn't return long after, but they didn't find much in the nearby desert, so Roy didn't let them go any further, and everyone stayed in the dark canopy, waiting for it to get dark.

During this time, Roy also began to take out the books he found in the library of Yolan Bryce City and look through them.

The demon's use of his own magic power is innate, and this talent is extremely powerful, and there are even rumors in some worlds that the magic of humans and elves comes from the demon.

But Roy knows very well that this is not the case, the magic circuit in the demon's body belongs to the origin magic, and for the origin magic, the demon can be said to be effortless, but if it is non-origin magic, even the demon needs to learn.

The mages of the Kingdom of Bradaka were scholars who specialized in magic, and their research was fruitful, and from these books, Roy saw their research on magic.

Scholars believe that the power of magic is actually a medium, used to communicate and call various elements existing in nature, in order to achieve the purpose of using and forming magic, and the power of magic determines the efficiency of this medium to communicate elements, for some powerful magic, if the efficiency of magic communication is low, then it needs to use spells or rituals to assist......

Roy reads these books with relish, although he doesn't know the words of this world, but with the system in hand, these are not a problem, Roy directly made a [translated konjac] and ate it, and it was all solved......

From today onwards, you can call me Roy Amon! Roy thought triumphantly.

While Roy was trying to learn some of the world-unique magic recorded in the book, he didn't know that the oasis they had passed through had welcomed a new group of guests......

This group of guests is also an army of the undead shrouded in a dark canopy, but unlike the dark canopy created by Kassandra, the dark canopy shrouded in these undead armies can actually move with the movement of the army! It can be seen that the person who released this dark canopy used this magic much more skillfully than Kassandra.

In this group of undead troops, there are not only low-level undead such as skeleton soldiers and ghosts, but also mummies, vampires, death knights, lichs, necromancers and other high-level undead creatures, and the most eye-catching is the low-flying sky above the troops, dozens of large, but tattered winged bone dragons!

These bone dragons are special undead creatures made of countless dragon bones, they are powerful undead at the top of the pyramid of undead creatures, and the empty eye sockets of the dragon bones are burning with the fire of the dead, even just looking directly into the eyes of these bone dragons, people can feel boundless fear.

This army of the undead, not only there are a large number of high-level undead creatures, but the size of its troops is also very large, and the person who leads this undead army with amazing combat power is led by a necromancer, he is riding a four-hooves undead war horse filled with the breath of death, carrying a scythe with a skull on his shoulder, wearing a black robe and a cloak, and under the hood, the necromancer's forehead has a huge spider tattoo!

Arantir, recognized as the strongest Death Lord in the Necromancer Nation of Herath, appeared in this oasis with his troops......
