Chapter 10 Cost, Side Effects, and Sacrifice
Two days later, Aize got the Blackforge Demon Sword from Claudia.

"Sorry to have kept you waiting, Black Furnace."

In a relatively remote corner of the Star Guide Academy, Aize held the pitch-black engine of the Black Furnace Demon Sword in his hand, felt the excitement coming from it, smiled, and activated it.

"Zheng!"

A bright red light shone out from the red Wanying crystal. The Wanying element responded to the power of the magic sword, forming a thick and huge sword guard, allowing the pure white sword body to extend from the open sword guard.

"Buzz!"

Aize held up the Black Furnace Demon Sword and injected star power into it, causing black lines to emerge from around the pure white sword body, circling all the way and converging into the Wanying Crystal.

The extremely strong heat immediately condensed on the sword, turning the pure white blade black.

Under Aize's control and the perfect combination of the Black Furnace Demon Sword, the heat this time did not dissipate like last time, but was all concentrated on the sword body.

"Um……"

Holding the Black Furnace Demon Sword with a blackened blade, Aize pondered for a while and began to talk to himself.

"Although I feel that this can be used very smoothly, the Blackforge Demon Sword is still too big."

The appearance of the Black Furnace Demon Sword is a big sword. Ordinary people may not even be able to lift it. The average Star Vein Generation may also find it difficult to wield such a big sword flexibly, which will cause many limitations in battle.

"It's better to keep it small."

As soon as these words came out of Aize's mouth, the Black Furnace Demon Sword in his hand suddenly changed.

"Zheng!"

The red Wanying crystal emitted a bright red light again, and the Wanying element once again turned into pitch-black lines that wrapped around the Black Furnace Demon Sword, circling and floating.

Under such circumstances, the Black Furnace Demon Sword disintegrated.

No, it should be said that it was rebuilt.

The thick sword guard that was originally formed almost disappeared, and the wide sword body suddenly shrank, compressing the extremely high heat for a second time.

After a while, the Black Furnace Demon Sword, which was originally almost as tall as a human, became as big as an ordinary sword. It was no longer heavy and huge, but looked flexible, light and dangerous.

Seeing this scene, Aize smiled as expected.

"You can really adjust the size freely, Black Lu."

Possessing the ultimate authority over weapons, as long as he holds a weapon in his hand, Aize can fully control its capabilities 100%, not to mention that this weapon has been recognized as the owner by his authority and has become his exclusive weapon.

Therefore, as early as the first time he held the Black Furnace Demon Sword, Aize knew what kind of abilities it had, and also knew that it could adjust its body shape freely like this.

"Yes, this is much more convenient."

Aize casually swung the Black Furnace Demon Sword, leaving a twisted heat stream along the path of the sword.

“Buzz!” “Buzz!” “Buzz!”…

As he swung the sword, Aize unknowingly increased the speed of his sword. With a slight movement of his body, he cut out a large piece of black sword light, making the sword body of the Black Furnace Demon Sword, which was condensing extremely high heat, hum with every swing of his sword.

If there were someone else here and saw this scene, they would definitely not believe that this was the first time Aize wielded the Blackforge Demon Sword.

The sword dance in which the whole body was immersed in it and the body naturally followed the sword, even in the eyes of a highly skilled swordsman, was no different from that of an experienced user who had been fighting with the Black Furnace Demon Sword for more than ten years.

Those who knew that Aize had just obtained the Black Furnace Demon Sword today and had never wielded the Black Furnace Demon Sword before would also feel incredible if they saw this scene, right?

At this moment, Aize's posture of using the Black Furnace Demon Sword showed no sign of having never used it before.

Even Aize himself felt as if he had been fighting together with the Black Furnace Demon Sword for more than ten years. The tacit understanding and cooperation between him and the Black Furnace Demon Sword were definitely far beyond any previous user of the sword.

"The unity of man and sword" - this word emerged in Aize's mind.

pity……

"The consumption of star power is too exaggerated."

Aize stopped suddenly without any warning, his face turned slightly pale, and he smiled bitterly.

"Is this the price of the Blackforge Demon Sword?"

Although pure Star Glory type weapons are very powerful, there is a price to pay for the use of each piece of pure Star Glory type weapons.

The cost is completely different depending on the type of pure Xinghuang weapon.

This is both a side effect and a threshold.

The cost of using the Black Furnace Demon Sword is that it consumes a large amount of star power.

The "large amount" here is not just a description.

At least, if it was used by an ordinary Star Vein Generation, his star power would be sucked dry in an instant.

"The original hero's star power is far superior to others. If we only talk about the amount, among the characters in the whole book, there are probably only two or three people who can definitely surpass him." "He was able to gain the recognition of the Black Furnace Demon Sword largely because of this."

"Compared to him, the amount of star power I have is much less."

Aize's abilities in all aspects are average in the Star Guidance Academy, including star power.

With star power of his level, even if he could use the Black Furnace Demon Sword, it would be sucked dry in an instant.

If it had not recognized its master, the Black Furnace Demon Sword would have sucked Aize dry in two or three seconds without any mercy, leaving him without even a chance to swing the sword.

The reason why it can be used for a period of time now is that, on the one hand, the Black Furnace Demon Sword is deliberately restrained and does not absorb too much of the master's star power; on the other hand, after recognizing its master, the Black Furnace Demon Sword itself has been strengthened by Aize's authority. Not only has its power been greatly improved, but even the cost of side effects has been reduced.

But even so, with Aize's extremely mediocre star power, he could probably only use the Black Furnace Demon Sword for a few minutes.

This is the result of the Black Furnace Demon Sword deliberately restraining most of its power.

If Aize wanted to unleash the power of the Blackforge Demon Sword to its full potential and increase its output power to the limit, he could probably only launch a few attacks.

"After all, it's because I don't have enough star power."

Aize said helplessly.

at this time--

"Buzz!"

The Black Furnace Demon Sword suddenly trembled, and a large amount of Wanying Elements was released from the Wanying Crystal.

"Black furnace?"

Aize was stunned for a moment and asked in confusion.

The Black Furnace Demon Sword did not respond to Aize, but instead concentrated the large amount of all-purpose elements it released on him, and even injected them into his body.

Then, Aize was surprised to find that his star power and even physical abilities were rapidly getting stronger.

"This……"

Aize opened his eyes wide, feeling extremely surprised at first, and then he was delighted.

"The Black Furnace can actually help me increase my strength?"

What exactly is going on?

This kind of thing never happened in the original book!
"correct."

Suddenly, Aize reacted.

"The Xingmai Generation was born because of the influence of the Wanying Element."

"The Wan Ying Jing Jing is a high-purity crystal of Wan Ying Su, which is itself a condensation of Wan Ying Su."

"In other words, as long as we use the Universal Element in the Universal Crystal to interfere with the human body, it is possible to promote the birth of the Star Vein Generation and even enhance the power of the Star Vein Generation!"

This is not something that can be done just by saying it.

But the Black Furnace Demon Sword has already recognized Aize as its master and has become Aize's exclusive weapon, becoming one with him. That's why it can actively release its own power through the connection of authority to enhance Aize's abilities.

"This is a real surprise."

Feeling the ever-increasing star power and physical ability, the smile on Aize's face became more and more intense.

But, not long after, Aize's smile disappeared.

Because, in his feeling, the aura of the Black Furnace Demon Sword itself was becoming weaker and weaker.

"Black Furnace! Stop now!"

Aize's face suddenly changed and he quickly stopped the Black Furnace Demon Sword.

But the Black Furnace Demon Sword had no intention of stopping. Instead, it continued to release large amounts of the All-Effective Element, making the luster of the All-Effective Crystal become dimmer and dimmer.

It is sacrificing its own power to make Aize stronger.

"Stop!"

After realizing this, Aize quickly controlled the Black Furnace Demon Sword and forcibly cut off the release of the All-Effective Element.

He completely controlled the Black Forge Demon Sword and turned it into his own exclusive weapon, which meant that Aize could ignore the Black Forge Demon Sword's will and control it by force.

The red all-purpose crystal then stopped releasing the all-purpose element and slowly retracted its light.
