Three days had passed quickly.
On this day, Rozen sat cross-legged in the courtyard, closing his eyes.
Inside his body, the magic circuits that he had gradually connected over the past ten years began to activate.
In the next moment, magical power surged from Rozen's body.
He tightened the magical power emanating from within himself, calming it, and then it spread out like ripples, extending to the surroundings.
These spreading ripples were akin to ultrasonic waves emitted by bats – imperceptible but capable of reflecting back at an astonishing speed upon contact with objects.
Rozen's skin touched these rapidly rebounding magical energies, and he read the information from them with great precision.
"A tiny ant crawled over the small stone on the left."
"A 2.3-pound snow block fell from the tree ahead."
"Three clan members of two males and one female are passing on the other side of the wall."
"The next-door servant is already cleaning the room and will arrive here soon."
Rozen seemed to resonate with his own magical power, accurately reading this information.
Successfully achieving this, Rozen opened his eyes, and a faint smile appeared on his lips.
"The Sixth Tier of Magician – 'Heaven's Eye.'"
He had finally reached this level.
"I caught up, Ten-nii."
Rozen stretched lazily, feeling pleased.
Because this skill usually required at least ten years of practice to attain. Those who could master it were generally well-known figures within the world.
That's precisely why Akabane Tenzen, who achieved this level at the age of twelve, was regarded as the most stunning genius within the clan.
Now, Rozen has also mastered this skill.
"Back in Fuyuki City, if I had 'Heaven's Eye,' I wouldn't have to worry about being sniped by Archer," Rozen thought.
As the name suggests, 'Heaven's Eye' allows one to see everything around them as if looking down on the world from the sky, seeing the existence and positions of all things.
It is precisely because of this skill that Akabane Tenzen can perfectly coordinate the puppets he controls, keeping the formation intact and never being deceived by Rozen's puppet feints. He accurately exchanges the positions of his puppets and understands the enemies' positions and attacks.
Now, Rozen has also mastered this skill.
"With the assistance of 'Heaven's Eye,' my control of the battlefield will be more precise. I can better manipulate familiars and even Servants, giving more effective instructions while also being prepared for enemy ambushes," Rozen thought.
"If I can continue practicing and expand the range of detection, analyze more detailed information, and make the detection incredibly precise, I might eventually achieve the ability of a radar or scanner," he pondered.
This requires continuous practice and improvement.
Even though they both possess 'Heaven's Eye,' the difference in precision leads to differences in strength. This is why Rozen's skills in 'Telekinesis,' 'Spiritual Vision,' 'Rigid Body,' and 'Magic Defense' all surpass Akabane Tenzen's.
These four skills provide significant help to Rozen:
'Telekinesis': Allows him to convert magical power into telekinetic force, manipulating the twenty puppets he controls, which is a fundamental skill for a puppeteer.
'Spiritual Vision': Concentrates magical power in his eyes, enhancing their sensitivity. When mastered, it can even see through walls and observe the flow of magical power inside human bodies. In the library, Rozen used this skill to see the presence of barriers.
'Rigid Body': Interfering with his own body using magic to strengthen it. For an ordinary person, using this skill would easily grant them physical abilities comparable to a martial arts expert who has trained for ten years. However, due to Rozen's originally weak constitution, even after mastering it, he can only achieve slightly higher physical capabilities than an average person and still cannot improve his stamina. Therefore, Rozen plans to use it in emergencies and train it to an astonishing level so that it can enhance the strength of familiars and Servants.
'Magic Defense': As the name suggests, it is a magical barrier, similar to Mash's 'Magic Resistance' skill. The principle is to form a shield with telekinesis to block enemy attacks. Advanced users can even inscribe magic circles on the surface of the shield, dramatically improving its defensive capabilities. It's challenging for people with weak 'Spiritual Vision' to reach this level, as they often can't inscribe magic circles on the telekinetic shield. However, Rozen has achieved it, making the defense of 'Magic Defense' almost comparable to the shell summoned by 'Giant Shell Summoning.'
With these four skills and the detection ability of 'Heaven's Eye,' Rozen is confident that if he returns to Chaldea, it will surely astonish everyone.
"By doing this, my abilities as a Master will leap forward, allowing me to better command, summon, and support Servants."
Just the thought of it makes Rozen feel a rush of excitement. If he could also learn the 'Crimson Wings Formation' and combine it with the puppet combat techniques passed down by the Akabane Clan, even if he commands multiple Servants, he will be more than capable.
"In addition, I need to continue honing my 'Summoning Arts' level and fully open the remaining magical circuits within my body to increase the usable magical power. Even though my body's age has become younger, I haven't lost my memories. Therefore, my 'Summoning Arts' level has steadily improved. So far, I've mastered several intermediate summoning magic.
Unfortunately, without fully opening the magical circuits, my available magical power will be limited, affecting my overall strength. In the past, I could summon large numbers of magic ants multiple times, but now, one summoning likely depletes all my magical power.
Only by fully opening all the magical circuits, I can use the maximum amount of magical power to support the consumption and enhancement of skills like 'Summoning Arts,' 'Puppetry Arts,' 'Telekinesis,' 'Spiritual Vision,' 'Rigid Body,' 'Magic Defense,' and 'Heaven's Eye.'
"From this perspective, it's hard to say whether it's a good thing or not that people in this world aren't influenced by Magic Circuits for their magical power."
In this world, Magic Circuits are not pseudo-nerves used to generate magical power. Magicians can cultivate their own magical power through practice, and by doing so, they can increase their magical capacity. In comparison, for Rozen, once all the Magic Circuits are opened, there is no possibility of further increasing magical power.
Although it may sound like the magicians in this world have greater potential, it's not entirely true. Cultivating their own magical power requires starting from scratch, unlike us, where opening Magic Circuits automatically increases the available magical power.
Moreover, the magical power in the bodies of magicians in this world is not limitless. The duration of their training, natural aptitude, and physical constitution all influence their magical power.
Considering these factors, magicians in this world still highly value talent.
"Alright."
Rozen patted his cheeks and stood up.
"It's time to go."
