Without a pen and unable to do geometric arithmetic problems for the time being, Jonah began to study the practical application of starlines.

The characteristics of the starline of the "bear" and the opposite "boat" are "light, heat, and morphological changes", and the illumination star array in the staff is the most rudimentary application, and the teacher has not allowed him to come into contact with the destructive application form, believing that Jonah is not mature enough to master the power of attack, until he leaves, he quietly throws the book to him, acquiescing to the astrologer's apprentice's ability to protect himself.

"Thank you, teacher. Jonah said in his heart.

Astrologers rely on mediums for their battles, with gems engraved with the stars, crystals, amplified staffs, single-use star array scrolls, potions that enhance the sensitivity of the starlines, consumables that make the starlines more recognizable in the sun, stardust, etc., their warlock robes are embroidered with Mithril thread for defensive arrays, and even the astrologer's badge itself is a multi-functional star array - none of which Jonah has all he has is a staff of illumination that is better than nothing, and an introductory textbook.

He couldn't help but feel a little distressed. Should Tobado be allowed to steal something?" Jonah pondered, feeling that it was a bit immoral to reuse the honest head of the room.

Quickly turning over the introduction and the original explanation, the first actual star array is the "scorching ray", which simply converges into a high-temperature ray of light after stripping off the energy of the interstellar line and shoots it in the specified direction.

Closing the book, he wanted to find a carrier to experiment with, there were no suitable materials nearby, and at the moment he missed his messy but resourceful little room in the Astrologer's Tower.

Jonah was helpless.

He asked Sibi to find a piece of charcoal and drew a few strokes on the stone floor, which was quite clear.

The girl in green squatted next to him and watched with great interest as he drew complex shapes in front of the door, and exclaimed from time to time: "Brother, this is a house! This is a turtle! Yo, this is Pit No. 6!"

Jonah pouted his lips good-naturedly, drawing straight lines, arcs, and tangents as accurately as possible, occasionally at the angles of the thick side figures at the corners of the book. The teacher always said that he was good at geometry and weak in arithmetic, and that he was a natural pragmatist, and that he was not suitable for research in the tower of astrology. In retrospect, that was a compliment.

After a quarter of an hour, the star array was complete, and Jonah stood up and mapped the entire star array with the figure in his head, without error.

"Sister, go away. He waved Sibi away, and Sibi blinked and said, "What are you going to do?" ”

Jonah looked at Ryuki pleadingly, and the brunette woman smiled and grabbed Sibby's neck and walked away.

Jonah closed his eyes and felt the vast energy of the countless starlines with his body.

The starline is always there, but during the daytime when the sun is strong, it becomes extremely difficult to sense the starline, and astrologers generally spill a large amount of star dust at this time, and the dust falls on the starline, emitting a golden light that is not recognizable to ordinary people but is quite dazzling to astrologers.

The starline between the bear and the boat was not too strong, so it became more and more difficult to find, and after half an hour, Sibi almost fell asleep in the arms of the dragon, and Jonah was barely catching the line, keeping his mental energy highly concentrated, and the starline was still looming.

He squatted down, pressed his palm on the input part of the star array, and silently recited: "Everything in the world is the projection of the stars on the ecliptic, and we exist, own, communicate, genetic, create, manage, share, change, transcend, realize, communicate, and introspect, all of which are overlooked by the starry sky. In awe, he always looked up (- Gilberto Gilberneon, Mentor of the Astrologers, 1305-1378 Continental Calendar). ”

The proverbs of the first astrologers gave him strength.

Jonah concentrated, using the arcane pattern of the star array as a bow, gently flicking the looming star line. The free energy floated down like crystal fragments, a vortex of energy invisible to the naked eye rose on the stone floor, and the power of the stars continued to condense, compressed by the star array in the core, Jonah felt the restless pulsation of the energy in the center of the star array, and he shouted "Be careful!" His hands gathered into a ball, squeezing the power of the stars out of his hands like he had done when he was a child bathing and playing in the water, and with a bang, a dazzling red light shot out, and in Sibby's exclamation, the astrologer's apprentice's attack spell accurately hit a bunch of weeds in the gap between the stone slabs three feet away, and the light smoke dissipated, and two of the three leaves of the weeds burned yellow.

“...... That's it?" Sippy was speechless for a while, pouting.

"It could have been better. Jonah was sweating profusely.

"Flutter. Ryuji turned around and was secretly amused.
