Kiyosuke, who returned to the room, also received the details of the file transmitted by Furuta, which recorded the whole process of the captain's investigation.

The owner of the file did not stay on the island for long, only for three days in total, but he recorded many details and solved many of Kiyosuke's doubts.

It turned out that the death line on the mountain was not as big as it is now.

Today, half of the mountain is dead, but thirty years ago, less than one-third of the summit was a dead area.

It can also be seen from here that the process of Rebungaku's death is probably the process of her breaking free from the seal, and Kiyosuke even experienced the expansion of the death domain himself.

In order to study this archive, Kiyosuke even gave up his daily meditation and spent the whole night carefully looking at the details.

......

Time flies like a white horse, and more than ten days pass in a flash.

As one of the least populated prefectures in Japan, Hokkaido is particularly well protected by the ecology, with a high forest coverage rate, stout trees huddled together, and only a small amount of sunlight can reach the ground with thorny grasses, and it is a primeval forest far from human settlements.

It is less than half a month before the start of school, and the breath of autumn has already appeared in the forest, and the sultry smell is mixed with the withered yellow leaves.

An autumn breeze blows.

"Rustling~" The silent forest suddenly sounded the faint sound of leaves dancing, followed by a series of rustling sounds, from far to near.

"Huh~" A figure appeared in the depths of the forest, leaping along the branches of the ancient tree, and soon he came to a towering ancient tree, a young man wearing shorts and holding a sword in one hand.

With a light step along the trunk of the tree, Kiyosuke jumped up and stood at the top of the canopy, stepping on a small branch on the edge, which was no thicker than chopsticks, and it was hard to imagine that there could be a person standing on it without breaking.

"I didn't expect that after the power of this spiritual fruit was completely digested, it would be able to help me go one step further." Kiyosuke stood on the tiny branch with a smile on his face.

In the past ten days, he has not been idle, he has been warming up with Gutian every day, and at the same time, he is also digesting the power of the spiritual fruit that remains in the body and is not fully digested.

After completely digesting this power, he was now only a thin line away from Class B, like a thin layer of window paper, which could be broken at the slightest stab.

But Kiyosuke understands that this is just his illusion, if he fails to break through again, it will take at least a few months of water grinding to break through this layer of windows, but it is no longer a fantasy to break through the B level a year ago.

Now that he has some of the characteristics of the B-class, in the depths of the "god", a small point of light has appeared at some point, which can only be discovered when Kiyosuke meditates alone and observes carefully.

It is also this small point of light that allows him to achieve the effect similar to light work now, otherwise, how can a branch with the thickness of his index finger bear the weight of his body.

If Kiyosuke guessed correctly, this point of light is the manifestation of the prototype of the realm, and when the point of light condenses into a ball of light that can be clearly perceived without meditation, it means that he has successfully advanced to the B rank.

At that time, he will begin to have all kinds of supernatural abilities, the most iconic is the ability to fly, which means that he will be completely separated from ordinary people and become an extraordinary life.

Although he hasn't advanced yet, after thoroughly digesting the residual strength, his strength has improved a lot, and if he fights Fujiwara now, he can completely make him unable to even cut himself with a knife.

"I wonder how high I can jump right now?" Kiyosuke stood at the end of the branch, his eyes moving.

Kiyosuke jumped lightly onto the main trunk, and if he burst out with all his strength, this small branch that was only the thickness of chopsticks would not be able to withstand his strength.

"Click~"

Kiyosuke's eyes froze, and all the strength was instilled into his legs, which seemed to be powerful springs made of extremely tough steel bars, and the green tendons burst in the calves, and the springs rebounded instantly.

"Huh~" The moment his legs jumped hard, the main trunk of the big tree was directly crushed, and Kiyosuke was like a cannonball rising from the ground, so fast that it was impossible to see it clearly with the naked eye, and in an instant, he flew up hundreds of meters into the air, and it was still rising.

“

Boom! ”

A sonic boom sounded, and at the moment of leaving the trunk, a sonic boom cloud appeared at his feet, and his speed exceeded the speed of sound!

"Huhu~" The sound of the wind passed by Kiyosuke's ears, and everything on the ground moved quickly out of his sight, and the clouds in the sky were getting closer and closer.

"Happy!" Kiyosuke laughed loudly, this speed is really cool, much more enjoyable than taking a plane or something, at this moment he finally experienced the thrill of flying, although he is not really flying now, just relying on the kinetic energy of the start to rise in a straight line.

500 meters, 1000 meters, 1500 meters....

Soon, Kiyosuke flew to an altitude of more than 2,000 meters, and the upward momentum finally began to weaken, the speed began to slowly decrease, and the gravitational pull from the ground began to pull Kiyosuke back down.

"I didn't expect that just a glimmer of light could make such a big breakthrough." Kiyosuke sighed a little, before this point of light appeared, he was afraid that he could only jump to the level of three or five hundred meters at most.

And now, after having a point of light to counteract the gravitational pull, he was able to leap to an altitude of nearly three thousand meters, although it was still far below the cruising altitude of a civil airliner, but it was also an altitude that cultivators below level B could not imagine.

If Furuta knew that Kiyosuke could jump nearly three thousand meters, I am afraid that his jaw would fall in shock, this height, even those three people may not be able to do it, after all, no matter how strong they are, they have not broken through to the B level after all, and they can't fly.

With the decay of kinetic energy, Kiyosuke's altitude finally stopped rising after barely breaking through three thousand meters, and after a short period of stagnation, he began to fall freely.

At this time, the help of that point of light is needed, otherwise if there is no buffer in free fall at a height of three thousand meters, even Kiyosuke will not be able to withstand such a heavy blow, and Kiyosuke does not want to become the first C-rank swordsman to fall to his death.

Thinking of this, Kiyosuke closed his eyes and began to meditate in the air, and the points of light that existed in the depths of the "god" began to flicker, and a wonderful force spread out from his body, helping Kiyosuke resist the gravitational pull from the center of the earth and slow down the speed of his fall.

At less than five hundred meters from the ground, Kiyosuke's falling momentum had faded a lot, and although he was still falling in a straight line, his speed had been controlled to a range that he could fully bear.

Dozens of seconds later, Kiyosuke rolled over in the air and stepped on the trunk of a tree with both feet, as if a huge falcon had landed on a branch.

"It's just a pity that I can't really fly yet." Kiyosuke shook his head, the feeling of flying was really addictive, but he also played kung fu again, and the time for the appointment with the skeleton woman had arrived.
