The defenders of the imperial capital have long found that the enemy of the other party is no longer a flesh-and-blood Senate warrior, but the undead legion that has swept the continent 200 years ago, they have continuously sent messengers for help to the imperial capital, but have increased the vigilance of the entire front, but for so many days, except for the increasingly dense dark canopy in the sky, the undead legion has not moved at all, which is a good news for the Morley defense line that is anxiously waiting for reinforcements from the imperial capital.

Of course, the human defenders of the Morry Line would never know that everything they saw in front of them was a huge illusionary magic. In addition to this, the orcs in the north attacked, and Senate in the south went west, all of which were part of the demigod lich's plan, although they all failed in the end, but they successfully held back the footsteps of the main human force, so that the plane projection of the demigod lich could have enough time to complete the arrival of the entire dark canopy.

The strengths and weaknesses of the undead are very obvious, so the first thing that the undead legion has to solve when they return to the mainland is to avoid rushing to the same mistakes as 200 years ago. In order to fight against the Holy Knights and the Priest of Light, the demigod lich harnessed the power of Maury's millions of unjust souls to open a dark canopy above the temporary base of the Legion of the Dead. Under its shroud, the undead who are aliens must no longer have to worry about the attack of magic such as the Holy Judgment, unless the caster can forcibly destroy the entire city, otherwise the magic they release that has special damage to the undead will be directly dissolved by the dark canopy. This principle is the same as the "Oasis of Life" of the Great Elder Druid, except that the Oasis of Life consumes the lives of the three Great Elders, and the Dark Sky uses the help of hundreds of thousands of souls who died in battle.

With this protection, which is akin to forbidden magic, this temporary base of the undead can slowly develop into a city of bones, and there are more than a million people killed in the nearby battle anyway, and the materials are enough. After learning the lessons of the year, the demigod lich changed the idea of a quick battle, but adopted the principle of step-by-step, it will slowly build one city after another of the undead, slowly encroaching on the living space of humans, if humans want to stop it, they must enter the city of bones to fight against the dark canopy that can greatly weaken the power of living beings, which is naturally more beneficial to the undead army.

Of course, the demigod lich is not the only one with these arrangements, the powerful but fragile lich under his command can create undead creatures, but these magic-specialized lichs are quite new to military command, so Conse will summon a frostbone dragon at Catherine's wedding celebration to cause chaos, and then let Nicholas take the opportunity to steal the corpses of the dead holy knights, these holy knights are powerful warriors and excellent military strategists in their lifetimes, and after being transformed into death knights, they can be used to command a large number of undead legions to charge。

A powerful dark aura roams the City of Bones, a corrosive poison for living creatures, but the best tonic for undead creatures. The undead creatures that had been transformed by the lichs with dark rituals, such as Talon, Blade Dance, and Silver Leaf, were all contented to bathe in this dark aura, and their master, Beray, stood very uneasy in front of Nicholas.

"So the whole operation still failed?300 shadow wizards still couldn't stop Ryan?" Nicholas wore a large lich robe that completely covered its body, and Bailey could only hear its cold voice.

"Yes, teacher. Bailey replied nervously, after all, this time it was nominally Senate attacking, but in fact Bailey was presiding, and as a result, after the whole battle, the shadow wizards that Nicholas had spent so many years preparing were all wiped out, how could this not make Bailey worried.

"I didn't think that boy had comprehended the power of the stars, didn't that mean that his mana could be used in a steady stream? Nicholas did not reproach Bailey, but said in a slightly thoughtful tone: "If Sandru can successfully lure him to join us, I believe he can step into the ranks of the Great Lich in five years at most, such a magical genius, we have neglected it in the past few decades, what a dereliction of duty!"

"Lure him to join us?" Bai Lei cried out, at this moment his heart was full of bitterness and jealousy, he was the most dazzling and brilliant magic genius in the imperial capital, that is** Faraz, the student of the division, is also unbeatable, but it is a pity that all this disappeared after Ryan appeared, it can be said that Bailey has become what he is now, but there are also some factors caused by Ryan, and now it has just had a little status in the undead army, but suddenly heard that his life's biggest opponent is so valued by his teacher, and can reach the unattainable realm of his teacher in the shortest possible time, how can this not make Bailey's heart feel bitter?

"Well, you don't have to ask about this matter, as a student of the teacher's lineage, if the Great Lich Sandru can't handle it, we can't do it either. Nicholas said, "What is the effect of the 'Skull Explosion' magic I taught you, and what are the special insights of the battle between you and Elendor?"

"Well, Elendor is also very strong, the three of them are also at a disadvantage when they join forces, and I used a skeleton evil blast, which can only severely damage him, and he still has the strength to continue fighting. There's also a little trouble, it's my former companion Maia's sister, and she seems to have strange powers......" Beley told all of this.

Before Bailey's words were finished, a violent fluctuation was caused from the center of the entire City of Bones, and Nicholas left Bailey and immediately flew towards that side, Bailey was stunned for a moment, and saw that his teacher did not say that he might also pass, so he ran after him.

Of course, Bailey's two legs were not as fast as Nicholas's flight, and by the time he arrived, the strong mana fluctuations had already appeared three times, and a black vortex had also appeared above the entire huge magic circle, and a cold aura emanated from the vortex, mixed with a slight crackling sound, which sounded very similar to the movement of the frozen river when the ice broke in the spring season.

The thirty-six lichs who presided over the entire magic circle saw that the spatial passage had been opened, and they desperately injected their own mana into it, and the flickering light of the magic array became brighter and brighter, and the black vortex began to expand gradually. It's a pity that this situation didn't last long, the dark aura emanating from the 36 lichs began to slowly weaken, and the light of the entire magic array also flickered several times in a short period of time, obviously the most troublesome thing happened, the mana of these lichs has been exhausted, and the entire ritual is likely to be wasted.

An obscure spell sounded from Nicholas's body, and the Grand Lich saw that the situation was not very optimistic and took it upon himself, and its addition immediately restored the entire magic circle to its original state, and soon expanded again. After a while, the entire dark vortex formed a black void, and with Nicholas's large string of magic spells, the entire black void finally stabilized, forming a void passage connecting the continent and the other world.

Maintaining the operation of a magic array does not consume too much mana, and Nicholas naturally retreats, and at this time, footsteps with loud echoes are heard from the depths of the passage. In just a few minutes, a large group of warriors wearing black rune armor walked out of it, that is, the death knights who had been stolen by Nicholas and transformed by the demigod lich himself. These Death Knights were once put on the Imperial Capital by demigod lichs to cause a New Year's tragedy, and then they were placed in the lower level of the Mad Lich Tower in the Otherworld, and now the void passage connecting the two planes has been breached, and the commanders of these future undead legions have once again come to this continent.

After hundreds of death knights passed, there was another sound in the passage, and at the same time, a strong putrid smell came out, this kind of stench that humans will vomit when they smell it will not affect the undead creatures present, only Bailey frowned slightly, although he can transform his body, but he is the closest to human in the entire undead army, and his human functions, such as the sense of smell, are still retained, so he is naturally uncomfortable with this stench, but it is just uncomfortable.

"Goo!" A crisp chirp came out, and Bai Lei, who was not far from the Void Passage, immediately felt a huge coercion, which reminded him of the scene that had appeared in the imperial capital. Sure enough, a frost bone dragon emerged from the teleportation channel, let out a chirp towards the sky, and then spread its bone-white wings and flew into the sky.

Dragon, Beamon, Hydra...... A large number of undead creatures made of the bones of powerful demonic beasts came to this plane through the void passage, and the city of bones, which originally looked quite wide, suddenly became crowded. Once the undead creatures made from the whole skeleton had passed, more giant bone golems began to pass through the teleportation circle. This bone golem is completely assembled from the bones of unknown creatures, and its principle is actually the same as that of assembled monsters, except that each bone that makes up these bone golems has a large number of magic spells, in a sense, they can be seen as the existence of half-undead creatures and half-magic items.
