As Diana's soul was withdrawn, her body's transfiguration could not be maintained, and she directly changed back to her original dragon form.

The Sword of the Fallen Prince was like two toothpicks for a brass dragon that was more than fifty years long, but it only left two very minor wounds on the dragon's body, as if it had been bitten by a mosquito, and it was quickly healed by the dragon's own self-healing ability.

Chen Yue didn't really kill Diana, but the brass dragon without a soul was no different from dead, just a hollow shell.

This is also Chen Yue's intention, the body of the brass dragon is still alive, as long as it provides the nutrients needed for survival, it can provide a steady stream of dragon blood and dragon scales.

Although the short-term benefits of this captive model are much lower than those of directly killing one-time harvests, this is a sustainable one-time gain, and the longer it is, the higher the returns, and it is only a matter of time before you want to exceed the high one-time harvest.

And when the sword of the fallen prince suppresses Diana's soul, Chen Yue can forcibly sign a soul contract, whether it is to transform the brass dragon into a frost dragon, or a blood dragon similar to Oni's, it is all up to Chen Yue's own preferences.

However, Chen Yue thought about it in his heart and finally decided to transform Diana into a blood dragon.

The Frost Dragon couldn't provide dragon blood and dragon scales, and Chen Yue hadn't unlocked the Frost Dragon's transformation array, so without the assistance of the system, he had a high chance of failing to transform.

On the other hand, the Transformation Blood Dragon only needs to slightly modify the magic circle that transforms Sarein.

Coupled with the fact that Oni can be used as a blueprint reference, and Christina's assistance, Chen Yue is confident that the transformation will be successful in the first time.

The most important point is that the blood dragon has a super-fast regeneration ability similar to that of a vampire, as long as it provides sufficient flesh energy, it can provide a large amount of dragon blood and dragon scales in a short period of time, which is more useful than the brass dragon that is still alive in the original body, and can greatly speed up the pace of strengthening the evil spirit class.

Chen Yue was even able to tame the brass dragon into a mount, which could be stored in the mount space anytime and anywhere, and summoned and used as a flying mount when necessary.

Since coming to another world, there is one thing that makes Chen Yue feel very depressed.

The vast majority of demigod-level professionals in the main plane have the ability to fly.

But Chen Yue, who inherited the powerful characteristics of the characters in the game, also inherited the ability of the characters in the game to not be able to fly, and if he wants to fly, in addition to relying on flying mounts, he can only look for those heroic soul equipment with the ability to fly, of course, after he becomes a god, this problem can also be solved.

"The leader of the Shadow Assassins is also available, and the Red Devil Scorpion King is a new research material, and Kel'thugad may have some new discoveries." Chen Yue muttered to himself.

The Shadow Assassins, in particular, can enhance the overall strength of the Scourge Legion's intelligence department, allowing the assassination team to operate even if there is no suitable leader.

Chen Yue thought about the transformation method of the Brass Dragon and the Wanderer, turned around and began to release the Black Blade Gate.

After the Black Blade Gate was fully formed, Chen Yue instructed Christina to take care of the ruins, and stepped into the Black Blade Gate with one foot.

Cameron and Bradrick had been waiting for a long time, and behind them was an entire army of golems.

Relocating the Arcanon requires them to manipulate the Golem to dismantle it in sorts, then transport it back to Naxxramas piece by piece by teleportation, and assemble it in an underground cavern dug out of Anubrekan.

The city-type Arcanon engine was too big for Naxxramas to fit in, and needed to be modified before it could be used.

Cameron used to build the Aoeng engine, and it was not difficult for him to make general improvements.

But now the improvements are not only as simple as reducing the size of the Arcanon engine, but also need to be modified to a structure suitable for flying fortresses like Naxxramas, and the energy output must also be changed to Shadow Energy, which is no easier than rebuilding one.

And most importantly, the urban Aonic Engine has some advantages in terms of energy output compared to the Aonic Engine that supports the Floating Island, but other than that, it is no match for the Floating Island Acanon Engine.

According to Cameron, the two engines are very different in terms of their attributes.

Instead of bothering to renovate, it is better to use the materials inside to remake an Arcanon Engine, so that some new alchemy circles can be added to it, and the research results of the three of them during this time have made this Arcanon Engine even more powerful than the Arcanon Engine on the Floating Island, and more suitable for Naxxramas's current situation.

After listening to Cameron's words, Chen Yue touched his chin and said: "I see, I thought it was too good, I thought that with this urban Olympic energy engine, the energy transformation of Naxxramas would be able to complete more than half of it." ”

"Master, you don't have to be too frustrated."

Cameron pointed to the shell of the Aoneng engine and explained: "The materials of all kinds of large Aoneng engines are the same, the manufacturing principle is the same, some of the technologies are also common, and even the core parts can be shared. ”

"In terms of structure, it is also similar, the difference is in the safety protection of the appearance, the proportion of energy output inside, and the size and service life of the engine."

Chen Yue was at a loss after hearing this.

He doesn't know much about this kind of high-end technical thing, no matter what the world is.

However, Chen Yue still understood the meaning of Cameron's words, according to the words of the earth, one is a large generator for civilian use, and the other is a military warship engine.

The factors considered by the two sides in the design and manufacture are not in the same channel, the military Aoneng engine is much stricter than the civilian requirements, to say the difference, the popular point is that the leather is durable.

Arcanists often develop advanced cores by developing the Floating Island's Arcane Engine, and then transfer it to civilian use to develop and produce advanced civilian Arcane Engines.

The Floating Island's Arcane Engine also embodies the limits of Arcane Empire's technology back then, and is one of the most critical technologies for building the most powerful Floating Island.

Chen Yue's city-type Olympic energy engine in front of them is a standard civilian Olympic energy engine.

The engine is usually housed in a cylindrical structure with a diameter of more than a kilometer, and the real core is a 100-meter-diameter metal sphere inside, and inside the sphere is a palm-sized plane core.

It is this small dimensional core that can provide the energy for thousands of years of operation of a large city.

The metal sphere on the outside is just a suppressor developed by the arcanists, which is used to limit the energy in the core of the plane from suddenly bursting out, allowing it to release the huge amount of energy in it slowly and steadily.
