Courtyard No. 91.

After a big battle, Ji Boying was lying in the bathtub contentedly, and behind him, there were two oirans rubbing their shoulders and pressing their heads.

As for the front......

Naturally, it was Zi Silk, a skilled beast master, who trained the giant Jiao that was completely wild in the water.

Ji Boying's eyes were slightly closed.

While enjoying the depraved and comfortable moment.

On the other hand, he was angry and trying to be strong, constantly thinking about how to achieve the exchange of spiritual power.

"After I came up with electromagnetic induction, I have been cutting the magnetic inductance line to seek a breakthrough, but I have ignored the difference between the spatial dimension of the talisman and the circuit."

"How can a two-dimensional talisman realize the magnetic inductance lines in the three-dimensional field of the spirit pattern cutting?"

"Could it be...... The talisman is destined to use only DC spiritual power? ”

Ji Boying sighed lightly.

If this is the case, his previous idea of substituting circuits into talismans would not work at all, and it would have been wrong from the beginning.

As for Ohm's law......

Maybe it's just a coincidence.

After all, Ohm's law can also be substituted for fluid mechanics.

Wrong......

This girl doesn't seem to have jumped out of the category of classical mechanics at all, right?

"Is it because the slave is heavy?"

Just as Ji Boying frowned, Zixuan's very charming voice sounded in front of her.

"It's just a little annoying, it's not your problem, you just go on."

Ji Boying glanced at the somewhat frightened beauty and said lightly.

It's not easy to get this Chongyang qi and blood, in the final analysis, Zixuan is just a hard-working worker.

Ji Boying, who was also a hard-working worker in her previous life, naturally would not embarrass her.

Really.

The beauty was obviously relieved after hearing his words.

Smiling like a flower again, on the assembly line, the screws are also working harder.

Well......

The screws here are giant screws.

The nominal diameter is four centimeters, and the standard length is eighteen centimeters.

Ji Boying couldn't help but feel a little happier when she saw her working so seriously and hard, and she looked willing and enjoyable.

But......

Just when he saw Zi Xuan change from the tongue of the third form of the Royal Beast Heart Sutra to the second type of the upper and lower hands......

Ji Boying's face changed suddenly.

It was as if lightning suddenly flashed in my mind, dispelling all the fog that obscured my vision!

It was as if he had seized an opportunity.

Ignoring that his natal beast was still in Zixuan's hands, he hurriedly sat cross-legged and entered a meditative state.

Zi Xuan, who was working frantically on the assembly line, was stunned for a moment after seeing Ji Boying change her posture.

Childe, is this trying to change his position?

Well......

This pose is really chic.

Come to think of it.

She continued to work hard......

——

After entering meditation, Ji Boying was directly immersed in her soul world.

He stood in the void with no attachment to it.

With just a casual move, a propylene fire yang thunder token suddenly appeared in front of him.

This is a memory engraved in the depths of the soul, and there are even relevant reflexes.

Therefore, it only takes one thought from Ji Boying to appear in front of him.

Ji Boying's right hand swung out again, scattering the animal skin talisman paper behind the propylene fire yang thunder talisman, leaving only the rune pattern.

With a move from his left hand, a cylinder appeared behind the rune.

Smack!

The crisp snapping of fingers rippled through the soul sea world.

The rune was completely attached to the cylinder in accordance with Ji Boying's thoughts.

"I'm so stupid, I'm really ......"

Ji Boying opened the Xianglin sister-in-law mode.

"I just know that it is extremely difficult to draw the rune directly on the cylinder, and even if it is painted, it will change the nature of the rune itself because it is distorted when the spirit pattern is outlined."

"But I didn't think of drawing on a flat surface first, and then attaching it."

"In this way, even if the rune is distorted, it will not change its original nature because it was already formed when it was drawn!"

"Even if there is a slight change due to excessive distortion, the nature of the talisman will not change much, and that change can even be completely ignored!"

"I'm really stupid!"

Ji Boying let out a long sigh, and immediately ended her Xianglin sister-in-law mode, her eyes staring at the cylinder in front of her.

His fingers twitched slightly.

It's like Tony is controlling the Jarvis system, very Dove.

"Movement is relative, it doesn't have to be a spiritual pattern to cut the spiritual force field, or the spiritual force field can be actively cut by the spirit pattern itself."

"It's like a fight, it doesn't have to be me attacking all the time, and occasionally I'm attacked, and it's a different taste......"

"So ......"

Ji Boying snapped her fingers again.

The cylinder, which was originally solid, was instantly hollowed out.

And that's not all......

There's also a small cylinder inside.

Ji Boying's thoughts moved slightly.

The small cylinder begins to move up and down pistons rapidly inside the large cylinder.

"No, no, no!"

Seeing the small cylinder running in the runes that changed the direction of spiritual power, Ji Boying hurriedly dispelled this thought.

"My current assumption is that spiritual power is input from the outside world, and this structure is to cut the spiritual force field by constantly changing the direction of spiritual power."

"Although the monk can change the direction of his spiritual power at will, this change has a forward time, no matter how skillful he is in controlling his spiritual power, he can't complete the direction change in an instant, right?"

Thinking of this, Ji Boying redrew a propylene fire yang thunder derivative talisman, and then passed vertically through the center of the talisman with a symmetrical axis, and finally spun rapidly in a cylinder with only a single spiritual power direction.

It not only realizes the spiritual force field of the spiritual pattern cutting, but also realizes the spiritual power change in the spiritual pattern.

Kill two birds with one stone......

Wait a minute!

Ji Boying watched as the talisman without any bending rotated rapidly in the cylinder.

I was stunned for a moment.

Immediately, he slapped himself in the face.

"My brain is really funny!"

After scolding yourself.

Ji Boying directly withdrew from the meditative state.

Looking at Zixuan, who was still working hard in front of her, Ji Boying hesitated for a moment, then took her into her arms, and then pressed on the edge of the barrel, entering the mode of seeking others rather than herself......

What's the saying?

Do it yourself, have plenty of food and clothing!

——

A few hours later.

Ji Boying left the No. 91 courtyard with mixed feelings.

In order to verify the model in his mind as soon as possible, Ji Boying did not return to the back mountain, but went to a trading house and found a few skilled craftsmen, asking them to help him create the structures he imagined in his mind.

Because the things that Ji Boying wants are very simple and the requirements are not high, they only need to meet the shape and function.

So......

In just a few moments, all the parts were built.

But......

During this period, watching these craftsmen forging, a new idea sprouted in Ji Boying's mind.

"I've come this far, why don't I just refine a rune like a rune treasure that can be used multiple times?"

"If it's just a one-time talisman, I need the craftsman to help me create the corresponding structure every time I make a talisman."

"In this way, it is completely contrary to my original purpose."

"But what I've refined is the same as the rune treasure, it's a talisman that can be used many times, so that's another matter!"

"But if that's the case, why don't I just refine the rune treasure?"

The moment this idea emerged, Ji Boying stood directly in place and fell into deep self-doubt.

"Damn!"

"Lao Tzu has been busy for so long in vain?"

Ji Boying looked at the iron pillar in his hand, and suddenly had the urge to smash him to the ground.

"That's not right!"

"It's different!"

"These two things are different!"
