This is also the reason why there will be a huge difference in the power of the same weapon, the same cultivation, and different cultivation.

In fact, it is not only the rune master who needs to comprehend the rules of energy, but also needs to be able to cultivate, the more advanced the ability to cultivate, the more needed, the comprehension of the rules of energy is not only helpful for cultivation, but also for the improvement of combat effectiveness.

Lu Fan couldn't help but think, if his fire-type shooting gun also used this structure, how terrifying would it be?

Immediately, Lu Fan shook his head, even if he could complete the transformation of the fire-type shooting gun, he didn't have materials with enough strength now, and apprentice-level materials couldn't withstand such huge power.

And the problem of this gun that can shoot is actually very simple, Lu Fan can see it at a glance, because Lu Fan has encountered such a problem before.

In a certain branch module that can shoot guns, there is a small rune pattern, and the rune master should be inattentive when inscribed, and he actually injected a little more energy, which causes the loss of this line when it is used, which will be one more point than other places.

If it was nothing to practice in his usual practice, because this tiny trace of damage to the material was not drastic, and because the young man surnamed Song had only mastered 12 energy fusions, the damaged branch module would not be used every time, which would not attract his attention.

But once it was time for a fierce battle, this drawback was revealed, and at this time, the material at the branch module had been completely worn out, and a slight hole appeared in the rune core module.

This is also the reason why Qiu Ying can't fix it, the materials are all broken, no matter how powerful she is, she can't repair it, not to mention, she is not so powerful.

"Uncle, if you can't help it, forget it."

Qiu Ying saw that Lu Fan looked at the rune module for a long time and there was no movement, and thought that Lu Fan had no choice but to be embarrassed, and after waiting for a long time, she said in a low depression.

"Well, I probably understand something, but I'm not a rune master, and I don't know how to fix it, can you tell me about this core module? Maybe I can give you some ideas. ”

Lu Fan firmly remembered the merged structure in his mind, with Lu Fan's solid rune foundation, as long as he clicked on this rune structure a few times and tried again, he would definitely be able to complete the replication of this structure, so he pretended to be puzzled and said to Qiu Ying.

Qiu Ying took over the rune core module, and after being stunned for a long time, she said slowly: "Actually, the structure of this rune that can shoot a gun is not complicated, if I am given enough time and enough materials, I may be able to make it myself." ”

"It's just that the materials of the core module are broken, and I can't fix it at all."

Qiu Ying said with some grievances, she has always wanted to prove her value in the team, only in this way will Sun Yunyi pay more attention to her, so that even if Sun Yunyi looks at her face, he will not drive Lu Fan away casually.

"Since that piece of material is broken, don't you want that piece of material?"

Qiu Ying showed a somewhat helpless smile when he heard this, Lu Fan's words completely exposed his identity as a layman, if the rune is broken, it can be removed, then the rune master is too easy to be......

"No, if it's other runes, maybe not, but this can shoot a gun, maybe it's not impossible."

Before Qiu Ying finished laughing, her expression became serious, but a storm had already been set off in her mind.

Seeing Qiu Ying's appearance, Lu Fan smiled slightly, if he directly told Qiu Ying how to repair it, Qiu Ying would definitely be able to repair this spear, but that would always leave a pimple in Qiu Ying's heart.

But now it's different, Lu Fan didn't say too many useful things at all, just knocked on the side, Qiu Ying didn't think about it so much at all, but thought that she thought of it.

Lu Fan was still racking his brains to think about how to prompt her, but he didn't expect Qiu Ying's comprehension to be so good, but he was really a good seedling of a rune master.

"The design idea of this energy shooting gun is to use quantity to make up for quality, and there are 48 branching rune modules, but in terms of the degree of wear and tear of the runes, Brother Song can only master the fusion of 12 energy."

"In other words, I don't need to repair all 48 runes, I only need to repair more than 12 runes, and Brother Song can use them normally."

Qiu Ying's head was running rapidly, and although she had closed her eyes, the rune diagram of the core module that could shoot the gun had already been engraved in her mind.

"Fix 47?"

"No, the parallel structure at the confluence of these branch modules is precisely calculated, and if there is one branch module missing, it will definitely not achieve the previous effect."

"And the previous merging and merging structure is also not usable, but fortunately, there are still gaps on the material to inscribe other runes, which means that I can calculate a new position by myself and re-inscribe the merging and merging structure."

At this time, Qiu Ying's mind was full of various rune patterns, of course, the largest piece was the rune map that could shoot the core module of the gun, and those small rune structures were constantly peeling off on this big map, and then from the depths of Qiu Ying's mind, another rune flew out to fill in the blanks.

After calculations again and again, attempts again and again, and then denials again and again, Qiu Ying finally deduced the most suitable modification plan in theory.

opened her eyes and touched her arms, but she felt empty, because her rune carving knife was lent to Lu Fan yesterday, and turned her head to look at Lu Fan, but Lu Fan had already handed over the rune carving knife understandingly, and had already injected her with a guide liquid.

Qiu Ying showed a grateful smile to Lu Fan, took the rune carving knife without saying anything, and pounced on the rune module in his hand with all his thoughts.

At this time, her mind was full of flashes of inspiration, if she didn't seize this opportunity, the next time she entered this state, she didn't know when it would be, and of course she wouldn't delay time at this time.

Qiu Ying's modification plan is very simple, which is to remove the broken branch modules, combine the remaining branch modules, and redesign a merge line structure.

Luckily, the broken core module was right on the edge of branch 48 and didn't affect too many of the other branches.

In the end, Qiu Ying's plan was to combine the remaining 36 branch modules and redesign the convergence and row structure, which seemed to be a simple solution, but it cost Qiu Ying countless brain cells, and after countless attempts, it was barely calculated.

Although this will make this capable gun no longer reach its maximum power, the 36 energy fusions are enough for the young man surnamed Song to use for a long time.

Qiu Ying held the rune carving knife, like Lu Fan, maybe every rune master is like this, when the rune carving knife is in his hand, he will forget everything around him and achieve absolute concentration.
