Chapter 852: Subsonic Kinetic Energy Weapon

However, the greater the power, the weaker the endurance. After all, the Flying Sword draws energy from the Magic Net, and the energy that the Flying Sword's Energy Core can cache is limited; every bit of improvement requires an exponential cost.

The Energy Core of Xia Duo's Flying Sword uses an Arcane Crystal, which is already the best material available at present.

If one were to stack Arcane Crystals, the volume of the Flying Sword would also increase, and at that point, the stacked Arcane Crystals might no longer be sufficient, creating a cycle that continues until a limit is reached.

It is similar to the limit of chemical rocket payload capacity often spoken of on Earth.

Additionally, under the premise of ensuring the strength and functional stability of the sword body, the Flying Sword requires as little Mithril as possible; in other words, it requires the Mithril in the core functional components to be of sufficiently high purity to be made small enough.

Given the numerous constraints, even if Xia Duo wanted to upgrade it, it would not be that easy.

It is enough for now, and he believes that for a considerable period of time, the Flying Sword will not become obsolete!

To be honest, in a situation where everyone has absolutely no concept of something like an invisible Flying Sword, this is almost a guaranteed-kill weapon.

Even with a concept and precautions, it is very difficult to deal with; after all, the speed is so fast, the attack is so strong, and it can also turn invisible. Aside from the few spells that can be triggered automatically, one can only take the hit head-on.

Relying solely on the Spellcaster's own reaction is not fast enough.

After finishing off a few Elves, Xia Duo did not attempt to track the Druid who had run away, but instead landed on the ground with wisps of light, thin mist swirling around his body.

"Mage Badelisi, Xia Duo has come to the rescue!"

"Ah! So it is Mage Xia Duo!"

Badelisi's mood at this moment could no longer be described as just overjoyed; the impact of that suppressed-to-the-extreme mood being released all at once almost made him lose his composure.

"Thank you for your help, Mage Xia Duo!"

As they were speaking, the 【Delayed Teleportation】 constantly active on Xia Duo detected someone teleporting nearby. He suppressed the thought of delaying it for the moment, only summoning the Flying Sword closer and adjusting its position to be ready to launch an attack at any time.

"You're welcome. You and I had an agreement long ago; now is merely fulfilling that agreement. I believe that when Mage Badelisi received my request for help, you wouldn't have refused either, right?"

"I wouldn't, I wouldn't! As long as there is a message from Mage Xia Duo or Lord Saville, I will immediately head over to support!"

Just at this moment, about ten meters away from the two, beside an Elf corpse, the Magic Net tangled violently and then quickly expanded.

A familiar figure appeared there, covered in dazzling spell light and wearing a vigilant expression! "So it is Mage Luodite!"

Xia Duo breathed a sigh of relief; it was good that it wasn't an Elf.

This Mage Luodite was also the captain of a team that had previously reached a support agreement with Xia Duo, and he was also a Pioneer who had recently attended a symposium that Xia Duo had entrusted Beilaila to organize.

After Luodite came over, he immediately noticed the corpse on the ground. While greeting Xia Duo and Badelisi, he also cast glances at the corpse beside him from time to time.

He kicked the corpse on the ground with his foot and said with a smile, "You two, am I late?"

"Not late, not late, it's good that Mage Luodite could come!" Badelisi said hurriedly, "By the way, I almost forgot, the crisis has been resolved, the others don't need to come over!"

After finishing, he hurriedly cast a Sending spell.

But unfortunately, before he finished casting, several more Advanced Rank Mages who had received the request for help teleported over.

By the time the message was finished, nearly ten Advanced Rank Mages had gathered here.

After briefly examining the few Elf corpses, the group exchanged a few words. Besides sharing information from their own missions, many were very interested in the highly efficient killing method that appeared here.

The corpses left by the Elves all had penetrating wounds to the brain, and the residual light reaction was extremely weak; either the attack was too fierce, or the Elves had no power to resist.

And under Badelisi's introduction, it was clear that both points were satisfied, which further illustrated the power of this efficient killing method.

It was just that Xia Duo did not want to make the Flying Sword known to everyone, but during the mission, it was unavoidable to use the Flying Sword; after all, the Flying Sword was designed and manufactured to kill enemies.

Once this thing appeared, it would inevitably invite probing from others. Rather than letting them guess wildly and cause unnecessary trouble, it was better to proactively give them a reasonable explanation.

Thus, he explained that it was a modified Force Field spell, similar to Magic Missile, and agreed to discuss it further at a symposium. Only then did the group leave readily.

As for the Force Field spell Xia Duo mentioned, it wasn't actually lying to them.

Force Field spells can indeed cause similar effects, but there was one thing Xia Duo didn't say, and that is—

The difficulty of defending against a Flying Sword and a Force Field spell is completely different!

Force Field spells can be neutralized as long as one uses a Force Shield, involving only energy level differences, but for a physical material attack like the Flying Sword, while a Force Shield can indeed resist it, it is not very effective—the effect is probably only two or three out of ten!

Perhaps some people might think of making a sword fly to attack; after all, Xia Duo had once rejected a magic sword that could fly out and kill enemies just by chanting a spell.

That was when he was in the Savile Territory, and he had "bought" it from Elf refugees together with Aoruipusi of the Silver Leaf Family. It was just that that magic sword was clearly not as good as Xia Duo's Flying Sword. When dividing the spoils, he chose other things instead of the magic sword.

This world does indeed have swords that can fly, but there is still a certain gap between a sword that can fly and a Flying Sword.

At least Xia Duo's Flying Sword comes with 【Invisibility】 and 【Vacuum Domain】, leaving no trace or shadow, and not even having a light reaction; it can be called a first-class assassination weapon.

And that expensive magic sword, enough for a fallen Elf family to treat as an heirloom, only had simple flight and attack capabilities.

The only thing worth praising was probably the intelligence of that sword's automatic attack!

But that intelligence was not like a Tower Spirit; it required locking onto a target within the user's line of sight to attack. Rather than calling it intelligence, it was more like it had pre-set, relatively complex attack programs.

If one understood its program, one could even toy with it like a fool.

Xia Duo had once guessed that that magic sword might have been used by ancient Elves for training Sword Art.

In terms of efficient killing ability, it was far inferior to the Flying Sword.

Or rather, Xia Duo's Flying Sword had long since departed from the concept of a sword; it just used the name "Flying Sword." If placed on Earth, in modern times, it could completely be called a "Brain-Wave Controlled Subsonic Kinetic Energy Weapon"! Naturally, supersonic and hypersonic speeds are also future upgrade directions for the Flying Sword!...

Returning to the location of Niya and the others, Xia Duo did not explain anything. Niya had already learned about it through Scrying spells, and as for the other Intermediate Mages.

Xia Duo only explained a few words simply; if they couldn't understand the situation by obtaining the information shared by Niya through Mind Link, they could only blame their own lack of ability.

It was they themselves who refused most of the shared information; Xia Duo had not stopped them from obtaining information at all.

After resting for a while, Xia Duo re-cast 【Mind Link】, adding back the few people whose links had been broken earlier.

Afterwards, the team continued to advance.
