However, after starting to get started, Xia Lin and the researchers found that this seemingly bumpy road was actually much smoother than they expected.

This is because even if a portion of the rune modules are extracted from the spell model, they will still be effective.

For example, according to the rune group of Flame Rune + Flame Rune + Mana Matter Rune of the Flame Arrow, you can get the weight of the Mana Matter Rune based on the Fire Rune.

By analogy, the research progress of Karl's laboratory was not fast, but it was not slow, and soon they came up with a series of weights of plastic runes.

"Kinetic rune weight ratio to fire rune: (1.07, 0.89, 0.98);

Weight ratio of Fire Rune to Frost Rune: (1.05, 0.90, 1.04);

……

Weight ratio of record runes to saved runes: (1.01, 1.02, 0.97)

……

Kinetic rune weight ratio to mana matter rune: (0.85, 0.79, 0.89);"

Through the data obtained from this series of research, Xia Lin discovered the secret of the different ways of connecting runes with each other.

Based on the 1.0 weight of the same rune, runes with a weight of no more than 3% can be connected with a common mental power node; More than 3% and no more than 10% of the runes can be connected by adding spiritual power nodes on the central line of the runes; Runes that exceed 10% of the weight can only be connected with spiritual power threads.

This is already a good research result, but there is a problem, that is, this law is not useful in practical applications.

Looking at these hard-earned data, Xia Lin was still a little unwilling. He always felt that there were some more essential laws contained in these data, but he did not have any ideas for further research.

"Xia Lin, what should we do next?"

Seeing that Xia Lin frowned at the data, and after thinking for a long time, he had no intention of continuing to arrange the task, Harper couldn't help but ask.

"No, I think there should be some patterns in these data...... Maybe I'm wrong, forget it, that's all for today's research! Great work, everyone! We're going to finish this research tomorrow."

Seeing that the sunset outside the window had already converged on the last afterglow, Xia Lin sighed and finally put down the experimental report in his hand. While everyone in the laboratory relaxed, they also showed a look of disappointment, and in everyone's opinion, this was another failure.

But the report he had just put down was picked up by one hand.

"Mr. Xia Lin, I want to study this data again, can I ask?"

Luna, as the person who put forward the conjecture of the "Rune Center and Spell Model Function Center Theory", saw that everyone had worked so hard these days, but there was no gain worth mentioning, and she pursed her lips and asked Xia Lin with some reluctance.

"Then don't study too late, and don't care too much about the usefulness of this theory, maybe this theory can give us some inspiration in other ways in the future! Basic research is often the cornerstone of future major results."

Charlin reassured that Luna cared more about the outcome than he cared about it.

"I understand!"

Luna nodded stubbornly, took the data back to her place, and began to study it carefully. One by one, the people in the lab also left to have dinner at a nearby restaurant and then returned to the Carl Lab to rest in a rented place in the surrounding area.

After Xia Lin had eaten dinner, he saw that the lights were still on in the laboratory, and simply told Luna to rest in Wyatt's original room at night, and seeing that she nodded seriously, Xia Lin let her go and study it by herself.

Anyway, for mages, staying up all night is not a big problem, and when this project is over tomorrow, their research routine will return to the construction of a ring of cleansing spell models.

In the absence of any new ideas, it is not too much of a burden to repeat the site selection experiment.

Charlin didn't do anything to Luna

I was expecting some research results, but at about three or four o'clock in the middle of the night, there was a sudden knock on Xia Lin's door.

The feeling of having his meditation interrupted was not very good for the mages, and Xia Lin opened the door with the irritability of not being able to concentrate, only to see Luna, who was holding the Shimmer Rune Disk, looking a little excited.

"Luna, why are you ...... so late?"

"Mr. Charin, I think I've found the relationship between the weight theory and the rune connection!

！」

「…… Wait, what are you talking about?"

Xia Lin's words were interrupted by Luna's hurried voice, and Xia Lin, who had just realized what Luna had just said, suddenly asked with wide eyes and surprise.

"I think I've figured out how the weight theory relates to the rune connection! Mr. Charlin!

」

Seeing that Xia Lin didn't seem to understand what he meant at the first time, the excited Luna pulled Xia Lin's arm and dragged him to the laboratory, and then took out a bunch of experimental reports and spread them out in front of him one by one:

"Mr. Xia Lin, look at this set of data and this set of data, and this set of data and this set of data......

Recovering from the negative state of having his meditation interrupted, Xia Lin quickly drew his full attention and began to study the data provided by Luna, and the more he looked at it, the more he realized that there seemed to be some patterns in it:

"Why do the coordinates of the spiritual power nodes connected by these runes seem to have some rules?"

"Yes, Mr. Charlin, if you look at these data again, there is indeed a pattern in them!"

Luna kept flipping through the experiment report and handed it to Xia Lin, who quickly skimmed over the experimental data, but the more he looked at it, the more he felt that something was wrong with what he had just felt, which was still the same as how he had felt when he had studied the data.

Just as he wondered and wanted to ask, Luna explained:

"Mr. Xia Lin, I found that if the weight of the soul rune is set at 1.0 according to the rune weight theory you proposed, then the weights of the remaining fourteen first-class runes in our laboratory are (1.32, 1.27, 0.85)......

Then according to the formula I found, I calculated it and substituted the number of rune nodes of its own, and I got this set of data.

And this series of data, don't you think it has some connection with the data of the coordinates of the rune connection nodes that I just showed you?

After comparing these weight data with the node coordinate data, I found that the node coordinates connected by the original runes were obtained based on these weight data, such as the connection node coordinates of the heating technique, which were obtained by transforming the weight value of the flame rune relative to the soul rune (0.84, 1.24, 0.96)!"

Luna excitedly told about her discovery, Xia Lin saw the formula related to the number of rune nodes provided by Luna, as if an electric current had passed in his mind, and his expression suddenly became solemn, and he immediately quickly checked Luna's conclusion in his mind, and found that it did match the results they measured.

It turns out that in the law he faintly felt before, this formula related to the number of rune nodes is missing! But there is one more question here, and Xia Lin asks instead:

"And what if it's the second rune connection? They don't share psychic power nodes, but take the form of adding nodes or even node pairs!"

"This is also a reference benchmark, and the principle is the same! And the coordinates of the nodes connected by the spiritual power thread can also be calculated in this way!"

As she spoke, Luna took out a pen and paper and began to substitute the data connected by the other two runes into the formula to calculate and demonstrate, but the conclusion was that it was in line with the actual data.

After looking at the data and checking it three times, Xia Lin finally let out a long sigh of relief, and nodded to Luna after a long time:

"I don't have any doubts, I think you've found the secret of the rune connection, Luna!

I didn't expect that this data would fit such a formula when combined and analyzed, and the formula you proposed made sense, and I think this theory should be called the Luna Rune

Connection Theory! It's called the Luna formula!"

"No, Mr. Charlin, this theory is not the work of me alone, but the work of everyone in the lab, and I think this theory should be called the Karl Rune Connection Theory.

And Mr. Xia Lin, there is another problem in this theory, that is, the runes are three-dimensional, the center of the rune is a point, and with the center of the rune as the base point, we still need to find the correct three coordinate axes to apply this theory, so this theory may not be as useful as we think when creating new spells!"

Luna shook her head a little uneasily after receiving such praise from Xia Lin, and then she thought of something and explained to Xia Lin with some sadness.

Specifically, Luna's method of finding the coordinates of rune connection points through rune weight theory is a four-step process:

The first is to find the center of the rune, which can be obtained by observing the generation of the rune effect and the subsequent calculation of the equation.

The second step is to establish a spatial coordinate system with the center of the rune as the origin, and then build a system of equations based on the runes applied in the spell model.

The third step is to obtain the weights of unknown runes by substituting the existing weights into a new system of equations built using the spell model.

The fourth step is to calculate the connection coordinates of the new rune by substituting a simple formula for the connection coordinates of the reference rune according to the obtained weight.

In this, only the establishment of coordinate axes based on the center of the rune and the position of the node has various deviations, because the rune is a three-dimensional space model composed of spiritual power nodes, and if there is no definite coordinate system, this theory is still of no practical use.

"Is that so...... I guess that's fixed too, Luna, do you remember the rune connection research we did earlier?

In this we get an interesting conclusion, which is that the runic connections are often symmetrical.

After adding symmetry, we can reverse the position of the rune nodes that make up the coordinate system according to the coordinates of the rune connection nodes, a rune always has only a dozen or twenty spiritual power nodes, and each node has three arrangements, which means that our computation has been reduced from infinity to three times the number of nodes.

Although it still seems quite large, there is still a glimmer of hope for success.

As for this theory, I think it's best to call it the Luna-Karl Rune Connection Theory."

Xia Lin pondered for a moment about Luna's question, remembered the conclusions concluded in the previous experiments, closed the test reports, and said to Luna with a smile.

After he submitted this last piece of the puzzle, the blueprint of the rune connection was finally presented in front of the two of them, and this Luna-Karl rune connection theory finally had the possibility of practice.
