"Ha ha ha! Child very good, you're absolutely right," he exclaimed, affectionately patted his son's head.
"Now that you've grasped the concept of chakra veins, can you think of a reason why we experience chakra strain when we overexert our chakra?"
As Aska comprehended the notion of chakra veins, he pondered for a moment before responding, "Perhaps our chakra veins have a limit to the amount of chakra they can handle. When we exceed this limit by using too much chakra externally, it causes strain on our chakra veins."
His smile broaden as he listened to his son's answer. "Good child, you understand what chakra strain is."
Now that Aska comprehended the concept of chakra strain, a sense of worry washed over him, and his face displayed a hint of panic.
Observing the look of panic on his son's face, he couldn't help but smile, fully aware of the cause of his son's distress.
"Child, now that you understand what chakra strain is, when you practice body strengthening, with your spine and leg veins strengthening, try to use excess amount of your own chakra outside your body, so you can reach chakra strain. This will gradually increase your chakra load of your chakra veins."
Aska's face lit up with excitement when he realized he could increase his chakra load of his chakra veins.
"Now Aska go and sleep and practice deligetly from tomorrow."
Aska nodded in agreement and headed to sleep.
Next day.
Aska was running towards the green rabbit habitat, while his body enveloped in a radiant white aura. Upon reaching the edge of the green rabbit habitat, he halted, slowly the white aura covering him faded away.
Aska climbed a nearby tree, he had spent the previous night pondering ways to achieve flight and way to decrease his chakra usage to overcome chakra strain. He carefully plucked big size leaves from the tree, and gather all the leaf in a neat pile before him. Aska jumped down from tree, he scoured the vicinity for long grass, meticulously collecting it, and when he believed he had amassed a sufficient amount, he climbed the tree while carrying the grass with him.
Aska picked a leaf, made a thick needle with his chakra in his right hand. Carefully, he pierced the leaf's edge with the chakra needle.
He continued to pierce the edges of the remaining leaves one by one. Finally, he chose three long blades of grass, deftly braiding them together. Aska used this braided grass as thread, he skillfully stitched two leaves together. Aska continued this process, pairing and stitching two leaves, until he had completely stitched reaming leaf.
With the leaves now sewn together in pairs, Aska took two pairs at a time and began stitching them together with the braided grass. After a while, he had stitched all the remaining pairs of leaf, resulting in ten sets of leaf plates, each containing four leaves, skillfully stitched together.
This leaf plates where Aska creative solution to reduce his chakra consumption. He picked all the ten sets of leaf plates and climbed down from the tree. Just like previous day, Aska focused his chakra on his back, slowly forming a wing emitting a radiant white glow.
Aska attached all the ten leaf plates on his wing, he infused the stitching of the plates with his chakra to reinforce their strength, ensuring they wouldn't easily break. After attaching all the leaf plates set, he channeled his chakra to shape the wing.
Unlike before, Aska today managed to double the wing's size compared to before, with each side reaching nearly 60 cm, slightly bigger than his hand.
Aska attempted to fly once more, he concentrated on his back, wings on his back began to move. In a blink of an eye they fluttered more rapidly, yet once again it can only blow wind around him. However, Aska sensed that if the wings were slightly larger, he might be able to truly fly.
Aska dispersed chakra wings from his back, he was was not disappointed due to this failure, but his confidence increased. He had spent the previous night brainstorming ways to reduce chakra consumption, and answer he came up last night was to use external objects, which was proven effective, after he experimented with the leaf plates.
Now he knew method to decrease chakra consumption, Aska envisioned crafting artificial wings from big feather and attach them on his back using his chakra, this would significantly reduce his chakra consumption.
To create these artificial wings, he had to collect birds feather, Aska started to search for something in the surrounding bushes. After checking several bushes without success, he finally stumbled upon some small footprints within one of them.
"Finally, found it."
Aska was searching for green rabbits footprints in the bushes, to set a trap.
Green rabbits occasionally ventured far from their own burrows in search of grass rich with chakra. To avoid being hunted by predator while eating, green rabbits dig burrows near grass rich with chakra and eat safely.
Aska found a burrow under on of the bushe, he was going to use this burrow to setup a trap for green rabbit. His plan involved using the captured green rabbits as bait to capture a birds.
After setting up trap for the green rabbits, Aska left the area. He continued to patrol the outskirts of the green rabbits habitat while he used his chakra to strengthen his body, spine, and leg veins. Aska also emitted his chakra from all over his body, which enveloped him in a white haze.
Aska strategically positioned additional traps for the green rabbits along the outskirts of green rabbits habitat before leaving the area.
Next day.
Aska checked the traps he had set for green rabbits. After examining half of them, he finally found one dead green rabbit in the trap.
Aska removed the dead body of green rabbit from the trap, he used his chakra to carry the dead body, then continued to check other trap. But Aska didn't find any other green rabbit in other trap. He then climbed a tree, placed the green rabbit in front of him, Aska cut the green rabbit in two equal half with the knife he formed from chakra.
Aska was going to use green rabbit as bait to capture bird. He climbed down from the tree, and approached a patch of tall grass, the grass blades reached his chest height. Aska began collecting the grass to make a rope, leaving only short 2 to 3 cm lengths grass standing to mimic the appearance of grass nibbled by wild animals. After collecting a substantial amount grass, he again climbed up the tree, sat on the previous spot.
Aska braided together 6 long strands of grass, to make a rope, he also strengthen the braided grass by compressing it with chakra, and extend its length by adding more grass at the end.
After some time, Aska completed making rope with all the grass.
Though he had never set a trap for birds himself, Aska had observed his father's setting trap for birds before. He jumped down from the tree with the rope and the green rabbit.
Aska cut the grass rope in half and used the half of the rope to make a net.
Aska cut four small equal pieces of rope from 20 percent of the reaming half of the rope, and tied them to the net four corners.
He then tied the four end together, spread the net on the ground, concealing it with leaves and grass.
Aska carefully searched the surrounding area, for a stone of suitable weight, to use it in his trap. After a while, he finally found a rock with suitable weight. With the rock secured, he carried and placed it near the net.
Aska climbed a nearby tree and, he formed a blade from his chakra, and cut two branches of equal length. With his chakra blade he cleaned both branches, he then repeated this process on three more branches.
After cleaning all the branches he climbed down the tree with them, Aska used his chakra to craft a makeshift hammer. He selected two branches of equal length and positioned himself beside the net. With precise blows, he anchored the two branches into the ground, maintaining a distance of approximately 30 to 40 centimeters between them. Subsequently, he brought forth a long branch which he had cut, and tied the branch with a rope, between the two branches previously hammered into the ground, making it act like a platform, just few centimetres above ground.
Aska's then broke one of the remaining branch into two smaller pieces, each about 15 centimeters in length. He hammered one of the smaller pieces opposite the two initially anchored branches. At this point, the trap was halfway assembled, one side featured a single branch anchored in the ground, while the opposite side displayed two branches anchored in the ground and separated by the net.
For the final setup of the trap, Aska tied the rock he brought before from the reaming rope one end and tied the other end to the small stick he had snapped earlier. He climbed the tree just beside the trap, suspending the rock from one of its branches, effectively creating a rudimentary pulley system.
Then he climbed down from the tree, and tied the net to the stick which one end was tied to the rock, which will act as the trigger for the trap. He fixed this small stick between the platform he created before with other branch, and lastly he fixed a long stick between the trigger and the single branch anchored alone on one side, which will act as the spring for the trigger. With these set up, the trap was complete.
Aska gently placed the bait on the stick functioning as the spring, then covered the reaming areas with leaves and grass, effectively concealing the trap.
