The Witch King Saruman was indifferent to what was happening outside of Isengard, the city had existed since its inception to be besieged, and even the Tyranids could not defeat it directly.

This is another magical barrier created by the Witch Kings for the purpose of war, and when a large number of Zerg individuals try to get close to the outer perimeter of the city wall, flames and lightning fall from the sky, covering a fifteen-kilometer radius around Isinger.

This is a hybrid forbidden spell, the witch kings have selected the two most harmful to living organisms from all the elemental spells, covering a large area of the insect swarm outside the city, and then an ultra-low temperature air mass has descended over this scorching hot field.

A large number of Zerg individuals who had survived the heat and electricity quickly shrank into a mass and shattered into pieces all over the ground in this drastic change of hot and cold alternation.

The casters of the New World experimented with a variety of different biotoxins on the Tyranids, and finally proved that the biotoxins that could be synthesized in this world were far from the limits that the Tyranids could bear, so they simply abandoned this method of killing and replaced them with a variety of composite killing spells that exceeded the ability of the organism to adapt.

Large swaths of the Zerg were reduced to pieces under the walls of Isengard, but the surging swarms quickly filled the previous void, and standing on the walls of Isengard, the swarms covered the entire land like a carpet with no edges in sight.

They roared silently, as if the whole world was trembling under their pointed feet, and the nest master was calling them!

Under the mobilization of the Witch King Saruman, the entire Esinger shook slightly, like a giant beast awakening.

Xu Yichen could clearly feel the vibration under his feet, and the vibration immediately turned into a violent shaking.

"Those elves in the era of the Elven Royal Court relied on the wreckage of various civilizations that crashed to the ground to shape floating cities, and they are proud of it." Witch King Saruman said contemptuously: "But they are just repairing on the original foundation, so that those antiquities can be used again, we are called the Witch King, how can we be left behind?" ”

At this time, the entire Esinger had risen from the ground and floated in mid-air.

Based on Issinger's use, the city looks like a pyramid from the outside, with few windows to the public, and at this time, as the whole city rises from the ground, its full view is exposed.

It has a structure that corresponds exactly to the above-ground part underground, and when it floats in the air, it is a cube with a diagonal as the central axis.

A large number of insects that had climbed on the outside of the city walls were shaken to the ground as if it were raining as Isenger lifted into the air.

As Issinger lifted into the air, the gravity of the area shrouded by Isengard's shadow changed, and the large swarm suddenly stopped, and then was crushed into a flattened mass, sap and carapace piling up.

The Witch Kings had studied gravity spells so thoroughly that Isenger could easily create a massive gravity equal to fifteen times his own gravity in the shadows he cast.

From the air, the projection area directly below Issinger was all sunken, and many Zerg individuals who had resisted the gravitational squeeze had been accumulated in the soil, churning hard to get out of this area.

But then the bottom of Isengh slowly opened like a blooming flower, and a transparent diamond-shaped crystal with a diameter of more than fifteen meters erupted into a dazzling beam of light, slowly sweeping the swarm below.

According to Issinger's Taling calculations, this high-temperature and high-energy beam swept through every Zerg individual with an energy level higher than the average with great efficiency, and all insects touched by the beam were turned to ashes in an instant.

"Alright, the automatic cleaning program is on." Saruman nodded in satisfaction, every Witch King likes to make himself a few expensive and interesting 'little toys' over a long period of time, and he is no exception.

What's more, this Witch King's version of the Floating City has also been sponsored by several other Witch Kings, and is a war fortress dedicated to fighting the Tyranids, and is most likely the most powerful magical creation in existence in the New World.

"Come with me, it's time to deal with the nest owner, it's been so many years that it's not very cooperative, and my patience has run out." The Witch King Saruman stretched out his hand to Xu Yichen, and Xu Yichen immediately rushed to an irresistible force to lift himself up and slowly floated to Saruman's side.

Xu Yichen didn't know what level of cooperation was in the mouth of this witch king, after all, in the past month or so, the nest master had cooperated with him to kill hundreds of thousands of Zerg individuals, but this witch king was obviously still not satisfied.

In Xu Yichen's ears, the humble begging for mercy from the nest owner was endless, although Xu Yichen would not have any pity for this alien race, he still had a certain 'kindness' towards the nest owner.

If the Hive Master does not die, this may become an invincible and enhanced version of the Yama Guild for the benefit of all mankind.

"Don't be deceived by that cunning bug, some of those Tyranid individuals don't even have brain tissue, they don't have the concept of individuals at all, and only when they reach the level of the nest master can they awaken their self-awareness." Witch King Saruman said to Xu Yichen: "For the nest owner, no matter how much the Zerg individuals are sacrificed, it is only a loss of protein, and for many years, we have tried to get more information about the core group of the Tyranid Zerg from it, but it has not revealed anything. ”

"Because if I do that, I'll die in no time!" A somewhat immature, but incomparably clear voice appeared in the minds of the Witch King Saruman and Xu Yichen: "I can't reveal any information about individuals with higher authority such as me!" ”

The Witch King Saruman showed a mocking smile: "Twenty-seven years, this is the first time you have used the human mind to communicate with me, but unfortunately, my research on you has come to an end, and your value to me has approached zero. ”

"Don't you want to know more about Chaos?" The nest master quickly mapped his consciousness: "I have a lot of information to share with you, I know the biological structure of every Chaos Demon!" ”

"It's a pity, if it had been a year earlier, maybe we could have talked, but now I don't have that much time." The Witch King Saruman made a complicated gesture in front of a huge steel door and said to Xu Yichen, "Next, you will become the first human besides the Witch King to see the true face of the nest master. ”

"It's a great honor." Xu Yichen looked at the metal gate that was twenty meters high and answered very expectantly.
