I have to get lucky right away.

Chapter 259 I've got it!
The game world operates in such a regular way that the day of the monster siege has arrived again. However, unlike in the past, none of the top players in the game have appeared outside the fortress that needs protection.

"Madman, is it ready on your end yet?"

Although I know that asking about progress is annoying, players in Hidden Village have already achieved results in fixing, transforming, and transferring spells. Many people have even completed the corresponding trials by learning their spells. Some players, such as Jar and Tyrannosaurus Warrior, have even passed all three trials perfectly because they can apply their knowledge to other situations. The only one they haven't been able to do is create a single spell for the selection trial.

Hearing the jar's question, the research fanatic sighed and dispersed the magic in his hands again:

"No, the structure of the screening ritual is not difficult to make, but it is very troublesome to complete a spell based on screening. After all, a spell is not just about screening out what you want to do, but about 'what you do with what you screen out', otherwise it cannot be considered a spell."

"However, to produce an output effect, you must first set a specific object, let the mana recognize the object, and select the object from the overall environment. This recognition mechanism is too difficult."

"I now feel that I need to master the other three basic skills before I can even touch this. Anyway, if you're interested, you can give it a try. I'll go and try to challenge the other three levels first."

The research fanatic, looking dejected, began practicing the three "passes" of Rasengan, Shunpo, and Armament Haki.

Seeing that even the most research-minded research fanatic had admitted defeat, Guan'er couldn't help but turn her attention to the other players who wanted to compete with the fanatic, but they all shook their heads as well.

In fact, the basic skill of "screening" is not much more difficult than the other three skills; in fact, it can be said to be the easiest.

The basic skill of screening is essentially about building a filter to filter out the desired targets from a specific source. The difficulty is never in weaving this filter, but in how to ensure that only the targets you specify pass through or do not pass through.

The reason why players haven't been able to figure it out yet is mainly because this world lacks the most easily filtered target—willpower.

Willpower is extremely sensitive to thought; it can be said that it can recognize anything that is thought.

However, in a world without willpower, to find a target to filter, a mechanism for identifying that target must be established.

This is similar to assembling a robotic arm that can grasp objects. For mechanical engineering professionals, this is not difficult. However, making the robotic arm accurately identify the object you want to grasp is not something that can be solved by mechanical engineering expertise alone.

In fact, at this moment, not only the players are thinking about this, but Feng Xue herself is also thinking about this issue.

In fact, given his mastery of the four basic skills, it wouldn't be difficult for him to independently develop a spell based on [Filtering]. For example, the simplest way would be to create a shield.

It refers to the kind of spells found in various fantasy and xuanhuan works, which envelop the caster to defend against attacks from external enemies.

This spell requires blocking incoming attacks while allowing one's own attacks to pass through. This process of identifying friend from foe is the screening process.

In the folk world, the solution to this problem is actually quite simple: directly identify friend from foe. Because of the existence of willpower, there is no need to consider so many factors; simply allowing attacks containing one's own willpower to pass through is sufficient.

But if the requirement is to not use willpower, that presents a different challenge altogether. However, he doesn't intend to actively interfere with the players' choices; ultimately, he's also curious about what surprises these young players can bring him.

As for whether it's truly impossible to make...

If they really can't come up with it, then so be it. If they don't even have this much creativity, Feng Xue doesn't expect them to come up with any high-quality spells. She might as well let them stay in the secluded village and experiment.

Although she thought this to herself, Feng Xue ultimately did not give up on these useful wet items. While the research maniac was rapidly mastering the Rasengan and starting to study Armament Haki, a dark cloud slowly drifted in from the horizon...

"Boom!"

The sudden rumble of thunder startled many players, but before they could react, large raindrops began to fall from the sky.

"Holy crap, it's raining! Isn't this crappy game's weather system supposed to only have thunderstorms in extreme areas?"

Staring into the rain, the players began to flee frantically, but just then, the research maniac who was busy gathering magic seemed to be struck on the back of the head by a flash of inspiration, and shouted!

"I understand! There's no need to go into such detail! A physical sample is fine too! It turns out we'll need to use other technologies!"

As he spoke, a soft glow emanated from his body, and an arc-shaped light shield appeared above his head.

The raindrops, as large as beans, were blocked by magic. Seeing this, the jar said:

"It's no use, this is a transformation of form..." Before he could finish speaking, the jar suddenly noticed that the barrier had started to leak!
He looked at the barrier in surprise, only to find that there were no holes in it. Only fine, misty rain fell down, soaking everyone present. Only the research fanatic was bathed in the misty rain, which, combined with his cultivator's attire, made him look like an immortal.

"Holy crap? What kind of trick is this?" Guan tried to build himself a rain shelter and then made a few holes in it, but no matter how small the holes were, only a line of water would fall down.

"I was also wondering how you can cast spells so fast?" The research fanatic looked at the jar's spellcasting, which seemed to be completed in the blink of an eye, and his eyebrows twitched. The jar, hearing this, scratched its head sheepishly and said:
"It's all because of that stupid trial. I can't say it changes the nature of the substance, but as for just the shape and color, it can be dealt with quickly. Don't talk about me, how did you manage? Did you pass it?"

"Not yet, but I estimate it's almost done." The research fanatic explained while refining his spell: "Actually, it's basically a sieve, but instead of just punching a hole, it's designed to allow only water droplets of a certain size to fall. So only the small droplets that splash against the barrier can fall down, while the others will flow away, creating this rain curtain."

"So I still don't understand how you identified it." Guan'er had also practiced screening, so she naturally knew the difficulties involved.

The research fanatic scratched his head, seemingly summarizing his words, before saying:

"It's a comparison. I've had the idea of ​​building a mana computer before, and this is a similar approach, which uses 'switches'... Wait! Holy crap, I get it! No wonder this spell failed! The filtering isn't a switch, but a program that controls the switch. Good grief, we need to develop a programming language based on switches, right? Let's start with something simple, beginning with 'if' statements..."
