Emperor Shi Tian was definitely a resolute person, and after having this idea, he immediately implemented it, and immediately found a gold-level material, the magnetic crystal core, which was the core essence of the magnetic crystal vein.

This thing was sold to Emperor Shi Tian by the lord who owned the magnetocrystalline mine, and there were only a few of them in the entire magnetocrystalline mine.

And through this treasure, the other party exchanged a large amount of arms from Emperor Shi Tian, which made his combat power swell again, and he could bully the neighbors around him who were greatly injured.

As for Emperor Shi Tian, he definitely won't suffer, I thought that this thing would be of great use in the future, but I didn't expect to use it now.

Without any nonsense, Emperor Shi Tian directly followed the method obtained from the fire of wisdom, and spent three days refining this magnetic crystal core the size of a human head into a short sword of about two feet, and marked countless special Yuan magnetic inscriptions.

The formed Yuanci Invisible Mother Sword is only at the silver level, which can be said to be a bit of a waste of materials.

If you change to a master, how can you refine it into a gold-level flying sword.

However, Emperor Shi Tian did not value the current ability of this thing, but more importantly its future potential.

After it has countless sub-swords, it can quickly improve its level and become stronger and stronger.

Next, Emperor Shi Tian couldn't wait to find more than a dozen strong dog-headed aluminum bats, teach them the method of cultivating the Yuan Magnetic Invisible Sword, and then give them some magnetic crystals for them to practice.

As a result, after half a month, these guys barely completed the refining of the Yuan Magnetic Invisible Sword.

And the dog-headed aluminum bat with the natal flying sword, the combat power exploded in an instant.

Relying on the Yuan Magnetic Invisible Sword's Yuan Magnetic Manipulation Ability, the ordinary dog-headed aluminum bat didn't even have the ability to get to the side, and was directly sucked and thrown to the ground by these guys with the power of Yuan Magnet.

In addition, as Emperor Shi Tian expected, the dog-headed aluminum bat can use the Yuan Magnetic Invisible Sword's Yuan Magnetic Manipulation Ability to greatly reduce the weight of aerial bombs, so that more aerial bombs can be consigned, starting with 20.

When these dog-headed aluminum bats become stronger and the Yuan Magnetic Invisible Sword becomes more powerful, they will definitely be able to carry more aerial bombs.

As for the stealth ability, it also made Emperor Shi Tian feel extremely satisfied, after the sword qi of the Yuan Magnetic Invisible Sword enveloped the dog-headed aluminum bat, it not only greatly increased the flight speed of the dog-headed aluminum bat, but also distorted the light around it, making it impossible for people to directly see them with the naked eye.

Of course, because the Yuanmagnetic invisible sword refined by the dog's head aluminum bat is only a bronze grade, the control ability is not particularly perfect, and there is a little unnatural distortion in the place where the light is distorted.

But the problem is that dog-headed aluminum bats usually fly at an altitude of two or three thousand meters, and they are still in the dim underground world, even if the stealth is not perfect, it is enough to avoid most ground gazes.

However, the stealth of the dog-headed aluminum bat is only the most superficial stealth, although the eyes cannot see, but the nose can smell the smell, and most of the other reactive means can be detected.

Therefore, at least for now, the stealth ability of the dog-headed aluminum bat can only bully unfamiliar enemies by surprise.

Once the enemy knows that there is a stealthy dog-headed aluminum bat on Emperor Shitian's side, then he will definitely be particularly vigilant, and various anti-stealth means will definitely make the stealth ability of the dog-headed aluminum bat greatly reduced.

But at present, being able to have such an invisible ability is already very powerful, and Emperor Shi Tian is very satisfied anyway.

And those dog-headed aluminum bats with the Yuanci Invisible Sword were also very excited, constantly flying around in the sky, and they also created a lot of tactical moves, and even some Emperor Shi Tian didn't think of it in advance.

For example, stealth diving and grappling attack, the dog-headed aluminum bat uses stealth to the top of other people's heads, directly controls the power of Yuan Magnetism, and catches the other party directly to the sky like an eagle catching a chicken, and then throws it down and falls to death.

Not to mention, if this trick is used to sneak up on mages, or archers and the like, it might really work wonders.

Even the powerful knights are easy to be caught by the dog-headed aluminum bat from behind with this trick.

Especially when a knight with heavy armor is caught in the sky by a dog-headed aluminum bat, it is difficult for his arms to attack the dog-headed aluminum bat on top of his head because of the heavy armor of his whole body, so he can only wait for death.

Emperor Shi Tian was particularly interested in this new tactic invented by the dog-headed aluminum bats, and discussed it with them, and as a result, he invented several new sneak attack methods.

For example, stealing other people's things, alchemy carriages, cannons, and some bulky logistics supplies.

These things are all left behind on the battlefield, and there are certainly not too many strong forces around.

If tens of thousands of dog-headed aluminum bats suddenly fly from the sky, grab things and run, hehe, I'm afraid that they can really complete the feat of robbery on the battlefield.

Even later, Emperor Shi Tian came up with the idea of using dog-headed aluminum bats to penetrate deep into the hinterland of the enemy country to carry out large-scale robbery.

Whether it is a resource point or a warehouse with weak defense, if it is really targeted by a large number of dog-headed aluminum bats, it will be emptied overnight.

When tens of thousands of dog-headed aluminum bats formed a lot of robbery legions, at least the lords of the dungeon had no choice, and they could only watch their materials being stolen on a large scale by these thieves who came and went without a trace.

Especially after cooperating with the portal of the Emperor of the Heavenly Emperor, the robbery ability of the Dog-headed Aluminum Bat Robbery Group is even stronger, because they can quickly send the stolen goods back and then continue to the next round of robbery, thus making the robbery efficiency to the maximum.

And just as Emperor Shi Tian and the dog-headed aluminum bat were discussing the formation of a robbery army, Yaslian came to his side in a necromantic airship to show him the latest flying class.

Emperor Shi Tian found that Yaslian's necromantic airship shape was really very hideous.

Overall, this necromantic airship is a shuttle-shaped, a fully sealed flight, 12 and a half meters long, three meters wide at its widest point, and thick in the middle at the two ends.

But in the bow of the ship, there was a huge skull, two eyes burning with green necromantic fire, and a mouth wide open, a weapon shooting hole.

On both sides of the boat, there are ribs side by side, and there are many green magic lines on them, which makes people panic when they look at it.

This white bone necromantic airship made entirely of giant corpses, under the control of Yaslian, moves flexibly and elegantly, can climb, dive and fly at extremely fast speeds, and the fastest speed can even reach 400 kilometers per hour, far exceeding the dog-headed aluminum bats and most of the flying arms.

According to Emperor Shakti's instructions, this necromantic airship, named Giant Gaze, did not have any means of attack, but had a lot of magic protection arrays, as well as magic circles to assist in flight and levitation.

Therefore, the protection and carrying capacity of this necromantic airship are very strong, and it can even carry up to 40 tons of materials.

After hearing this, Emperor Shi Tiandi's eyes suddenly lit up, and he couldn't help but say, "This can be used as a transport ship!"

"Yes. Yaslian nodded and said: "I designed this necromantic airship according to your idea of military-civilian integration, in normal times, it can be used as a civilian transport ship, and when fighting, it is a combat airship with all kinds of weapons." Because this guy has rough skin and thick flesh and flies fast, as long as the weapon is powerful, he can have very strong combat effectiveness. The most important thing is that ordinary transportation can also train a large number of excellent drivers, and there is no need to pay additional training costs. ”

"Good idea, good airship!" Emperor Shi Tian immediately asked excitedly, "How many shooting holes have you prepared?"

"In addition to the giant's mouth, there are two shooting holes on each side, and up to five 20 mm six-barreled cannons can be placed, and each plan can be responsible for firing in a conical area of more than 150 degrees from the front. Yaslian said with a smile: "A class like the dog-headed aluminum bat is not a problem to be a hundred!"

"Hahaha!" Emperor Shi couldn't help but laugh.

Yaslian was so furious by his laughter that she couldn't help but say, "Lord, do you think I'm bragging?"

"No, no!" Emperor Shi Tian waved his hand and smiled: "I just think it's too coincidental, if a few days ago, this giant of yours stared at the necromantic airship, maybe it could defeat the dog-headed aluminum bat with one hundred points, but now I'm afraid it's difficult." ”

"Why?" asked Yaslian with a puzzled frown.

"Because the current dog-headed aluminum bat can already use flying swords!" Emperor Shi Tian said, explaining to her about the Yuanci Invisible Sword.

Moreover, Emperor Shi Tian also asked those dog-headed aluminum bats to demonstrate the use of the Yuan Magnetic Invisible Sword.

After reading it, Yaslian couldn't help but smile bitterly: "The lord is really powerful, Yaslian is really willing to bow down." With your Meta-Magnetic Invisible Sword, these dog-headed aluminum bats may be able to defeat my necromantic airship with three or five of them. ”

"Hehe, that's not necessarily. Emperor Shi Tian said with a smile: "If you had already taken precautions and did not install metal weapons in the necromantic airship, then the dog-headed aluminum bat's Yuan Magnetic Invisible Sword would be useless, after all, the physical lethality of the Yuan Magnetic Invisible Sword is relatively small, and it is difficult to break through the protective circle of the Necromantic Airship." At that time, I'm afraid that dozens of dog-headed aluminum bats won't be able to defeat your necromantic airship!"

"But the problem is, necromantic weapons and equipment are scarce after all, and our mainstream is still metal firearms. Yaslian smiled bitterly, "Moreover, if the dog-headed aluminum bat uses an aerial bomb, no matter how strong the defense of the necromantic airship is, it is easy to be torn apart." ”

"That's right, now these guys can even use the power of metamagnetism to control the bomb for a short flight, your necromantic airship is so big, it's easy to be hit. Emperor Shi Tian smiled and said, "But if you are bent on escaping, the dog-headed aluminum bats may not be able to catch up with the necromantic airship." ”
