Lu Fan in the White Tower didn't know anything about what was happening in the outside world, and at this time, he was worried about the rune shield.

The rune shield is the surface, and the attack it resists is the point, so all along, the Federation's rune shield technology has given people a feeling of chicken ribs, because the rune shield can't resist the attack of the same level at all.

Of course, after more than a hundred years of development, there are not a few anti-heaven rune shields in the Federation, but they are all the products of the accumulation of countless precious materials, and they have little to do with rune technology.

But it cannot be denied the role of the rune shield, for example, in the prevention of some emergencies, the rune shield is still quite valuable, as well as the role of the rune shield to isolate poison gas, the rune shield of large military fortresses, all of which make the Federation never stop the research of rune shield technology, and even, keep increasing investment.

It's just that it has had little effect.

And Lu Fan's water-type rune shield, according to the parameters provided by the system, can not only resist attacks of the same level, but even resist one or two high-level attacks, it is not impossible.

Almost the moment he saw the parameters, Lu Fan had a vague plan in his heart, perhaps, when he finished refining the water-type rune shield, it was when he left the White Tower.

Because, after having the water-type rune shield, his chances of surviving on the front line have increased too much, as long as he is on the front line, he is sure to deal with those who want to be against him.

In the past month, he has spent all his time except cultivation studying the rune shield, and after Tan Yuan changed back the materials, he has also tried several times, but without exception, he has failed.

The runes of the water-type rune shield are not complicated, the first part of "Rune Basics" is the rune foundation and some simple rune structures, these knowledge are enough to deal with the water-type rune shield, Lu Fan vaguely felt that it was not that his runes were just not enough, but that he did not have enough understanding.

This is really a strange feeling, but Lu Fan vaguely felt that this was the truth.

From getting "Rune Basics" a few months ago, to making wind-type guns and fire-type guns, Lu Fan has always regarded runes as a language, and runes are indeed a language, but now Lu Fan has found that his thinking was too limited before.

Chinese is a kind of language, and the law written in Chinese is a kind of rule, and if the rules written in Chinese are the rules used to bind the human beings of the Federation, then the runes are also a language.

Lu Fan felt that the content written in the language of runes was the rule between heaven and earth.

Lu Fan even thinks that the myths and legends on the earth may be true, and the legend that those immortals and saints can follow their words, perhaps, what those saints say is the runes.

In other words, before the earth, it was possible to cultivate, but for some reason, this inheritance was cut off.

Thinking of this, Lu Fan suddenly had the idea of going to those miracle places of the Federation, such as Stonehenge, such as the Great Wall, such as the pyramids.

Perhaps, it will really allow him to discover some great secrets.

Of course, this idea was vetoed by him for the first time, if he dared to appear in the Federation now, within a second, he would definitely be directly knocked unconscious and taken away.

And the reason why he didn't succeed in refining the water-type rune shield was only because although he had mastered the basic rune and the basic structure of the rune, he didn't understand that kind of rule.

The previous wind-type gun-type and fire-type gun-type guns were like making sentences, Lu Fan had mastered the foundation of runes, and there was a template provided by the system, and it was not so difficult to make a sentence.

Just like a child who has just entered elementary school, he can read and write, and he can find those phrases and ask them to make a sentence, although they will make mistakes, but if they make a few mistakes, they can find the right way.

But the water-type rune shield is different, the working principle of the water-type rune shield is much higher than that of the wind type and the fire type can shoot guns, just like writing an article, even if you can read and write, but you may not be able to write an article.

As a language, those lines are just its appearance, and the real content is actually the rules contained under these lines.

Therefore, the teaching video provided by the system only provided a template for Lu Fan, after all, it was just a video, and it could not make Lu Fan really feel the content inside, which was the reason for his failure.

And these were summed up after he went to the help area to check countless questions about runes in the past month.

Of course, Lu Fan will not really answer those questions in the help area, he just checks them, and then verifies them one by one with the knowledge of "Runic Basics", even if there are questions he knows, he will not answer.

He doesn't want to cause a sensation like last time, and now he has no shortage of contribution points.

sighed and turned off the teaching video again, this is already Lu Fan doesn't know how many times he has watched the teaching video, he sometimes wants to get into the video to see what it is, however, this idea cannot be realized after all.

This month, his gains are not small, not only has he a deeper understanding of the runes, but his cultivation is also slowly but firmly improving.

But he still couldn't refine the water-type rune shield, and there was always a sense of urgency in his heart, and the longer he stayed in the White Tower, the more unsafe he felt.

After turning off the video and summarizing it, Lu Fan decided to go to the help area again, these days, in order to avoid people's eyes, every time he goes to the help area, he will not stay for too long, so there are still many problems in the help area that he has not checked.

opened the door, but found that Bai Ling was standing outside the door at this time, his right hand was raised slightly, and he had reached the doorbell, and after seeing Lu Fan come out, he was slightly stunned, and showed a charming smile to Lu Fan.

Lu Fan frowned, he couldn't say that he was disgusted with Bai Ling, but at least he didn't like it, after all, every time he met Bai Ling, there would be nothing good, and it was a little difficult for such a person to make Lu Fan like it.

"Is there something wrong?"

Of course, Lu Fan's frowning action couldn't hide an old fox like Bai Ling, but she didn't say anything, they could understand Lu Fan's feelings, and even sympathize with them.

But understanding and sympathy do not mean that she will let him go, whether it is personal ambition or the future of the family, this trace of sympathy will not be allowed to haunt her heart.

"Mr. Lu Fan, I came to you this time, I really have something, why don't you invite me in and sit down first?"

Bai Lingyan smiled, didn't wait for Lu Fan's invitation, walked into Lu Fan's room by himself, as if he had come to his own home, made a cup of coffee casually, and then sat on the sofa.

Lu Fan was secretly glad in his heart, fortunately he had just collected the rune carving knife and materials, otherwise, he would really have been stolen by this woman.

However, his mood did not improve by half because of this, because Bai Ling's name was Lu Fan, not the pseudonym Lu An he used, which meant that the other party had seen through his identity.

Knowing his identity, this is nothing, Lu Fan suspects that his identity has long been known by them, but the other party has not been silent before, and he will not report his identity.

At this time, the other party said so, then, there must be a change in things, and this change is probably not a good thing for Lu Fan.
