After a while, Yaro suddenly woke up.
"Isn't this a ready-made communicator?"
As early as when he was at Owl Academy, Yaro had the idea of making communication equipment, but due to all the troubles that followed, he ran out of the academy before the communication equipment was completed.
"This trick can not only be used as a means of communication, but it is also an excellent detection trick, which perfectly complements my lack of means."
Although the Cat-shaped Fist can sense the movement around it, it cannot intuitively see what is causing it, and the range it can sense is also too small.
Just like when he first arrived in the Kingdom of Llanelli, if Yaro mastered the Water Mirror Technique, he could use the Water Mirror Technique on the river. He would be able to find the Perrin Manor very quickly, without having to waste time in the wild.
Of course, if you want to make good use of it, you must first understand the basic attributes of Water Mirror Technique.
The back window of the wooden house quietly opened, and one after another water balloons the size of quail eggs flew wildly.
Just like dripping rain, if it doesn't fall on the ground or on your body, it's difficult to notice that it's raining.
The water polo in the quail eggs is no more than larger raindrops. Even in the daytime, it is difficult for people to detect it. What's more, it is already dark. As long as you are careful not to be caught by the light from the window, you don't have to worry about being discovered.
…
"The fastest release can fly 13 meters, but because the speed is too fast, the water ball shakes seriously due to the wind, and the scene displayed by the water mirror is too blurry."
"If you want to maintain a stable scene on the water mirror, the maximum speed cannot exceed half a meter per second. If there is wind, the result may be even worse."
"After the water ball hit the ground, it shattered directly, and the internal magic pattern structure was also destroyed."
It can be seen from this that water mirror technique is best used in advance, or used in conjunction with other methods.
"How far can the signal of Water Mirror Technique be transmitted at its maximum?"
The farther the signal can be transmitted, the greater the space used.
If you want to know the maximum distance that the water mirror signal can be transmitted, the best way is to leave the wooden house and find a piece of flat land outside to test it step by step.
But now the enemy is in the dark and we are in the clear, and if we act carelessly, we may be plotted.
——The remaining refugees from several surrounding towns have basically gathered here. Since the Fernando family’s goal is to establish the realm of the undead, aren’t these gathered refugees just a piece of delicious fat?
As long as this refugee camp is eliminated, it will be difficult to find such a perfect natural dangerous place in the future. Like dominoes, it will sweep from the rear where the power is empty until the entire earldom is completely destroyed!
"The Water Mirror Technique might be useful soon. Why don't we verify the method of using it together with the Water Mirror Technique now."
For now, Yaro can only think of two ways to cooperate.
One is to borrow a transparent device, such as 'glass' or 'ice', and then place the transparent device on the hot air balloon to continuously monitor an area.
Then use the 'Feather Falling Technique' in conjunction with it.
"Borrowing the principle of 'dragonfly touching water', we can make the observed water polo float forward."
"The hot air balloon is too eye-catching now. Let's use the 'Feather Fall Technique' first and see the effect."
Still copying the homework according to the answers.
The moment the water polo was released, a "Feather Falling Technique" was quickly attached to it according to the "Dragonfly Touching Water".
Looking back, Yaro felt refreshed when he saw the dim scene on the water mirror.
"It really works!"
'Dragonfly Pointing Water' can convert wind resistance into upward thrust. This thrust will offset part of gravity with each other. The remaining force that is not completely offset will only make the 'water ball' move forward while slowly rising, and will eventually be maintained at a balance point.
The water polo itself is not affected by too many external forces, so it can naturally shoot stable scenes.
"Because the structure on the outside cannot continue to be controlled, the water polo will rise in an arc. When it reaches the peak, it will circle around in a small circle, and then continue to rise again and again. This trend is a bit like falling and falling leaves."
"If we adjust the angle again, can we let the 'observation water balloon' circle around to check the surrounding situation?"
This level of modification is not difficult, and Yaro quickly found a suitable alternative structure from the previous plan for designing the 'Featherfall Technique'.
It is a variant structure of the 'Wandering Dragon Shen Technique'. With the help of the initial velocity of the 'Water Polo' and the deflection effect of the 'Feather Fall Technique' on the resistance, gravity and resistance are converted into centripetal force and deflection force, thus forming a circular swinging motion.
After calculating that there was nothing wrong in theory, Yaro began to operate in practice.
After copying too many answers, Yaro has acquired a certain degree of muscle memory. He can already perform the 'Marked Water Ball' in the 'Water Mirror Technique' without looking at the drawings on the wall.
Of course, this is also related to the relatively simple structure of the magic pattern of the 'marked water ball'. For example, in the water mirror technique, Yarrow cannot use it independently.
“Try it and see how the new structure works.”
It's still the same way, first cast the 'Mark Small Water Ball', and then quickly attach the 'Feather Falling Technique' to it.
result……
Snapped!
A few drops of water slowly slid down the wall.
Yaro slapped his head: "I almost forgot that this is not an open space, and we have to consider the obstruction of the wooden house wall!"
"The initial speed of the water ball must be accelerated, and the arc must also be increased. If the initial speed is accelerated, it can rise faster under the structure of the 'Feather Fall Technique'. Only by increasing the arc can it bypass the wall of the wooden house."
After modifying some parameters, Yarrow released the water ball again.
Soon, an inconspicuous little water ball flew out of the window again. It looked like there was a wireless rope above it. It was suspended and began to circle and swing the moment it was pushed out, circling backwards. flight.
But at this moment, the little water polo that was doing regular exercise suddenly lost its stability.
It's like the wireless rope in the middle is entangled with something. Although the ball is still orbiting, its orbit is getting smaller and smaller, and it is still rising rapidly.
Yarma, who was looking at the water mirror, immediately discovered the problem. At the same time, he heard the sound of the window shaking, and immediately discovered the cause of this change.
"Mountain breeze... Fortunately, this wind blows from bottom to top. If the wind blows from other directions, the centripetal force balance of the water ball may collapse. Once the centripetal force balance cannot be maintained, the water ball will fall immediately."
Yaro looked at the scene on the water mirror and wrote down the conclusions in his notebook.
[There can be no wind at high altitudes, and in many cases the wind direction at high altitudes cannot be sensed on flat ground... Doesn't it apply to high-altitude environments? 】
[Also...even in the low-altitude environment, there are many changes. The wind direction will change after all. The Feather Fall Technique attached to other objects cannot be controlled at any time like the 'Wandering Dragon Shen Technique'. Once the outside wind direction changes with the initial Throwing them is different, and observing the trajectory of the water polo will still be disrupted. 】
…
The 'Observation Water Balloon' can be compared to a 'paper airplane'. The 'Feather Falling Technique' released is its wings. Once thrown, it can only be allowed to float on its own.
However, a 'paper airplane' is just a 'paper airplane' after all. The cost is not high, and sometimes it can be thrown repeatedly.
A few paper airplanes can monitor drones, which is definitely a good deal.
[With this method, there is no need to use the pendant to lift off and observe the direction for subsequent pathfinding. After all, the pendant is fixed with the spell of a formal wizard. For the magic power of an intermediate apprentice, the burden is too great]
After looking at the scene on the water mirror and confirming that he had arrived in a specific direction, Yaro looked at the water polo in the sky.
"It's almost twenty meters away, right? What's the signal limit of Water Mirror Technique... Hey! Wait!"
Yaro suddenly discovered something and carefully observed the top.
"Why are there light spots on the top of the mountain? Do they also have guards on the top of the cliff? How did those guards get up there?"
