Blue Sword

Sidrifa caught the Ax of the North Wind again.

This was the third ghost ship she had destroyed. The so-called "destroy" means that all the enemies above are killed, leaving only an empty ship.

She then jumped towards the fourth ghost ship, but this time the distance seemed a bit far away. More than one meter away from the side of the ship, she helplessly fell towards the sea.

William frowned in the distance, but had no intention of going to the rescue. If a girl with a pirate background drowned in the sea, it was indeed not worthy of his rescue.

Several banshees flew over from the narrow space between the ships, trying to possess Sidrifa who was about to fall into the sea. If she is possessed by these banshees, the risk of drowning in the sea is much higher - not everyone can resist the invading possession of ghosts while still keeping their head floating on the sea to breathe. .

Sidrifa stabilized her body during the fall, and then stepped down on the sea with her left foot. The moment the toe of the boot touched the water, a layer of ice quickly formed on the sea surface, supporting her left foot.

Then the ice surface spread all of a sudden, forming a "ground" with a radius of about 2 meters for people to step on and stand on. Sidrifa stood firm and threw an arcing North Wind Ax, freezing all the approaching banshees, and the ice cubes fell into the sea with crackling sounds.

With the North Wind Ax back in her hand, Sidrifa looked around with the ax again, wary of possible attacks from around her.

However, the expected shot of bone spears did not appear, because while Sidrifa was making a fuss inside the undead fleet, the Norman fleet behind them also rushed into the formation and began to get close to each ghost ship. Boarding battle.

So much so that the battlefield had become extremely chaotic at this time. Sidrifa continued to observe the surroundings for a moment, and found that there were sounds of shouting and killing everywhere - most of them were made by the Normans. On the undead side, even the extraordinary ones were accustomed to being as taciturn and unsmiling as the undead.

So Hildelifa plopped into the cold sea water.

Most undead cannot swim. Due to their bone density, the Skeleton Clan will sink directly into the water; the Vampire Clan can go into the water but hate it because if their flesh and blood deformation occurs in the water, water and blood may be mixed together.

Since ghosts can fly freely, they are almost the same in water as in the air, but their field of vision in water is narrower; corpse witches tend to swell their embalmed bodies in water, so they also try to avoid going into the water as much as possible.

Therefore, Sidrifa swam in the sea for a while, but no enemy noticed her. Until she quietly swam to the rear of the undead fleet, the bottom of the ghost flagship.

Then he quietly poked his head out of the sea and looked at the tall undead ship.

How to get up there?

The surface of the undead ship is covered with a large amount of moss, seaweed and barnacles, making it slippery to the touch. It would be a dream to climb up with these things, not to mention the large number of ghosts wandering above the head. If you haven't climbed up for a while, Once on the deck, I was afraid that I would be possessed by a ghost and fall off, and then I would be unable to move and drown in the sea.

How to do it? Hildelife stared at the rusty iron pieces covering the side of the ship in a daze, and suddenly remembered something Aske once taught her...

"Do you know the law of electromagnetic induction?" Ask asked one day in the small teaching class at Fire Island Manor.

"What induction and what law?" Hidrifa asked.

"The law of electromagnetic induction." Asker took out two small magnets. "When the current flows through, a corresponding magnetic field will be generated. The direction of the magnetic field can be divided into positive and negative, and the magnet will be acted upon by force inside."

With a "pop" sound, the two small magnets were attracted together.

"Huh?" Hidrifa had never seen a magnet before, so she was very curious about the phenomenon in front of her. "This is..."

"This is the effect of magnetism." Asik replied.

"Hold up your thumbs and make a fist. When the current flows along the direction of the four fingers, a magnetic field will be generated along the direction of the thumb. The stronger the current, the stronger the magnetic field..."

"Um, ah, oh." Hidrifa nodded repeatedly, but it looked like she didn't listen at all.

"Why should I teach you this? Because it can give you powerful mobility." Seeing that she was not interested at all, Asker could only change his strategy and said seductively, "Imagine that you slapped an electric current in the distance. Then an electric current will be generated around you, and the magnetic fields generated by the currents on both sides will attract each other, and you will fly directly over..."

"Fly there? How to do it?" Upon hearing the word "fly", Hilda Lifa was really interested.

"First, you need to find a fixed conductor in the distance, such as metal, and then shoot a ring current towards it." Asker described, "That is to make the current surround the target conductor and rotate clockwise from your direction. Normally, people need to make coil conductors and apply electricity to create electromagnets.”

"But you don't need to, because Thunder is your sequence ability. You can ignore the laws of physics and freely manipulate the direction of electric potential and current."

"As long as a strong ring current is generated on the surface of the target conductor, and then a ring current in the same direction is generated around you, due to the direction of the magnetic field, a strong magnetic field attraction will be generated between you and the target conductor."

"Then, if the target conductor is firmly fixed in place, you will be pulled towards it by the huge magnetic force; conversely, the target conductor will be pulled towards you."

…

Hidliba, who was soaking in the sea water, quietly raised an arm, and electric current shot towards the iron sheets wrapped around the side of the ship.

If it is ordinary lightning, then the current will rush around on the iron sheet, flowing from places with high potential to places with low potential. However, under the control of Sidrifa's ability, when the electric current hit the iron piece, it immediately ignored the distribution of electric potential and began to rotate along the surface.

If any electrical engineer were here, they would sneer at Sidliefa's behavior and intentions at this time: Are electromagnets that easy to make? Assuming that Hildafa has the weight of an ordinary person, then the magnetic flux required to absorb her whole body is...

However, this world does not strictly follow the laws of physics, so Hidrifa soon felt the existence of some invisible magnetic field.

The electric current in her hand continued to radiate, as if it was firmly attached to the iron piece like a cable, and more electric current swirled around her.

oh? Oh oh oh oh oh! Is this what is called magnetism?

Hidliba suddenly increased her power output, and immediately she flew out of the sea and shot towards the side of the ghost flagship.

It wasn't until she landed on the deck again that the bright beam of electricity, like a grappling hook rope, dissipated from her hand.

Then, the densely packed undead on the deck all turned their heads and stared stiffly at her sudden appearance.

I received a notice today that I need to self-check the author's remarks of the published chapters to avoid being blocked. Please take a leave of absence for the afternoon update. Thank you for your understanding~
