Upon learning that Hua Jun's team had made new progress, Lin Li quickly put down the document in his hand and said to Zhang Guanghua:

"Xiaozhang, please invite Academician Hua in."

A moment later.

Hua Jun walked in from outside.

During this period of contact, Lin Li found that it was actually quite simple to judge Hua Jun's mood:

You just need to look at his expression.

When Hua Jun wore a Sun Xiaochuan face, it meant he was in a bad or average mood.

But when Hua Jun's eyebrows relaxed, and you could vaguely see his head slightly bobbing, it meant the little old man's mood was very, very good.

At this moment, Hua Jun's expression was of the second type.

Combining it with the related content Zhang Guanghua just reported, Lin Li couldn't help but smile:

"Old Hua, has your team made another breakthrough in the research of talismans?"

Hua Jun raised an eyebrow at him, let out a cocky humph, and with the aura of a big boss settling an account, he heavily slapped two talismans on the table:

"Hehe, Old Lin, can you guess what these two talismans are?

Guess correctly, and I'll treat you to Da Dong in Modu!"

Lin Li immediately raised his eyebrows:

"Whoa, Da Dong? That's quite pricey, it seems your results this time are impressive."

With that, he began to carefully observe the two talismans in front of him.

In the past period, Lin Li had handled quite a bit of information related to cultivation, and his vision was quite broad by now.

Just the understanding of the cultivation field, he could easily rank in the top ten among local personnel.

After carefully studying the two talismans, Lin Li touched his chin and guessed:

"From the lines... these two talismans aren't that complex; they should be Tier One Talismans.

I can't recognize the one on the left, but the one on the right...

Why does it seem like Hua Xiaomo's Tier One Sealing Talisman on his wooden cage? The kind where five sheets are used in one set?"

Hua Jun gave him a thumbs up, saying:

"That's right, both of these are Tier One Talismans.

We'll talk about the one on the left later; the one in your hand is indeed a Tier One Sealing Talisman—or more accurately, this is one of the five sealing talismans on Hua Xiaomo's wooden cage."

Upon hearing this, Lin Li couldn't help but have a question mark appear on his face: "?"

"Old Lin, don't rush, listen as I explain slowly."

Hua Jun casually walked to the desk, pulled up a chair, sat down, and said:

"Old Lin, you should remember the basic principle of the Sealing Talisman, right?

The core is one sentence: without considering concave polyhedra, five points can form up to six faces."

Hua Jun picked up a pen after speaking, drew a diagram on a blank sheet of paper, and then pushed it in front of Lin Li:

"Simply put, it's like this. Two regular triangular pyramids are joined at the base, forming a hexagonal prism with dihedral angles equal, and creating an independent space inside."

Lin Li nodded as he looked at the diagram:

"I understand this; it's basic math knowledge."

Then Hua Jun made a few more strokes on the paper, continuing:

"The central projection of the model after two regular triangular pyramids overlap is at the same location. I marked the internal projection with dashed lines.

And when the projection's dashed lines turn into vectors... Old Lin, you're a science student too; you should know what this means, right?"

Lin Li pondered for a second and replied:

"Vectors have directions, so these five points can retract and project onto a centroid, which means they can also unfold inversely from the centroid. Is this what it means?"

Hua Jun snapped his fingers, a hint of excitement appearing on his face:

"Exactly!

In the field of high-energy physics, this inverse vector unfolding of centroids is known as space scattering, and it's widely used in the field of aerospace engines; our Chang'e's engines use this technology.

Simply put, this technology disperses the five points in a bundled or singular form, spreading them on the projection plane's point center along a predetermined orbit, thus constructing the most stable spatial geometry."

Just as Hua Jun mentioned.

This space scattering technology is widely used in aerospace, and many times particle colliders also involve related concepts.

Seeing this, some might find it strange:

Doesn't this technology sound quite simple?

Just like fireworks, they shoot out and scatter into a field of stars, right?

Unfortunately, this is a very incorrect understanding.

The key to inverse vector space scattering is not just letting the centroid point scatter but ensuring that the scattered vector arrows successfully reach the predetermined positions, thereby constructing a standard five-point, six-face combination.

Also known as a hexagonal prism or regular spindle shape with equal dihedral angles.

The space formed by this regular hexagonal prism is very stable and balanced because the sphere center of the regular triangular pyramid is on its height, and the matter or ability transferred through the vector axis can expand and contract perfectly.

Currently, only six countries in the world have mastered the five-point, six-face space scattering technology, with the Rabbit, the Eagle, and the Bear ranking in the top three, the Bear relying on inherited foresight from ancestors.

The Eagle has gone a bit further in this field compared to the Rabbits, currently achieving 39.6 meters with a jet force of 20 kilograms cumulative weight, while the Rabbit has broken through 45 meters.

It must be said, in the field of aerospace, we still have a long way to go.

But fortunately, in recent years, our speed of catching up has been very fast, with breakthroughs happening at about 1.3 to 1.5 times the speed of the Eagle in related fields.

Moreover, since the front-end barrier in this field is 70 meters, within 70 meters, there's no situation of getting harder the further you go.

So, there's a pretty good chance for the Rabbits to catch up to the Eagle's position—which, in some sense, represents who can first send humans beyond the solar system.

Bringing the focus back to the command center.

After listening to Hua Jun's explanation, Lin Li couldn't help but ask:

"Academician Hua, I've understood the concept, but what does this have to do with the Sealing Talisman?"

Hua Jun glanced at him, pointing to the Sealing Talisman on the table:

"Old Lin, do you know how the cultivators of the Damo Realm generally use Sealing Talismans?"

Lin Li shook his head; he indeed hadn't seen the relevant scene.

"This is how they use it: after finishing the spell, they throw it all out in one go."

Hua Jun made a gesture of scattering flowers, then continued:

"Since the Damo Realm has no concept of a five-point, six-face body.

These bumpkins... natives don't know how to calculate the orbits. After activating the talisman, they just throw it forward aimlessly, waiting for the talismans to form a closed space on their own.

So these Tier One Sealing Talismans are mostly used for targets with severely limited movement, or for small fellows like Hua Xiaomo who squat down and cover their heads defensively at the slightest provocation."

As he spoke.

Hua Jun's tone suddenly rose a few notches, his face flushed with enthusiasm:

"But we're different, Old Lin; we have a mature five-point, six-face scattering technology!

Currently, in the aerospace end, we can already achieve wrapping individual weights of two kilograms, cumulative weights of 10 kilograms in a colloidal membrane, scattering them into a standard regular spindle shape through a thrust orbit, needing only 0.343 seconds over fifteen meters!"

Hua Jun got more and more excited as he spoke.

He pressed both hands on the desk, leaning forward, his facial hair all flaring:

"Old Lin, do you know what this means?"

Without waiting for Lin Li to answer, he picked up the Sealing Talisman on the table and shook his wrist vigorously:

"A ten-kilogram thrust launcher is about 0.125 cubic meters in volume, with each side about 50 centimeters long.

But this talisman weighs only about 15 grams, it doesn't need a launcher of that size!

Our team has initially developed a short-container projectile, placing five talismans inside through precisely calculated orbits, with a chip inside setting the space scattering guidance.

When the short-container hull reaches the designated position or hits the target, these five talismans will quickly fly out along the preset orbit, forming a standard sealed space within one second, enclosing an area of about 30 cubic meters."

Listening to Hua Jun, Lin Li suddenly realized something from his words. He stood up suddenly, and with a serious expression asked, "How far is the range of this short-container projectile? What's the size?"

"The projectile length is about fifteen centimeters, weighing around 300 grams, with a buffer and fixing device at the front end to ensure the talisman's trajectory won't deviate. As for the launcher size..."

Hua Jun made a shoulder carry gesture: "About the size of an RPG launcher."

Lin Li's chest heaved heavily a few times, and finally, he slowly said:

"So, it can be used to capture... a two-headed bull?"
