However, the creatures living in that forest are far fiercer and stronger than those found elsewhere, possibly because of their vigorous life force.
Many of the fierce beasts inside are four or five times more expensive than similar beasts from other regions.
Since they are far stronger than ordinary beasts, capturing them is naturally much more troublesome, which also makes their prices higher.
As for the food and medicinal herbs produced in the forest, they are only about twice as expensive as those from other places.
Ordinary people have no real use for them, and they are considered valuable mainly because they are rare.
Only individuals with status and strength are able to afford them, which is why the price is only doubled.
Tsunade used materials such as tiger bone every day to brew medicinal soups that nourished Sora's body, while highly nutritious ingredients like tiger meat were prepared as his meals.
It perfectly illustrated the saying that scholars require poverty while warriors require wealth.
Who besides someone with Tsunade's wealth could afford such extravagant consumption?
A single meal like this would not seem shocking, but eating like this every meal, every day, would require an astronomical amount of money.
Furthermore, Tsunade discovered that Sora's body possessed astonishing absorption abilities that far exceeded those of other powerful people at the same level.
Because she did not need to worry about overburdening his body, she combined those ingredients with medicinal herbs and chakra to develop a new solution similar to the previous Nutrient Solution.
This new solution possessed far greater nutritional value, and its effectiveness was more than ten times stronger than the previous one.
However, the cost of producing a single bottle of this Nutrient Solution was enormous.
The reward from five standard B-Rank missions combined would only be enough to create one bottle.
But this meant nothing to Tsunade. If she ran out of money, she would simply go and take it from the gambling dens.
In her words, the money she took was not even a fraction of what she had already lost in those places over the years, so she was merely collecting some interest.
With Tsunade's dedicated care, Sora fully recovered within one week.
This experience even triggered a breakthrough in his strength, placing him just one step away from reaching the Jonin level.
Once he truly stepped into the Jonin level with his current combat ability, he would be unmatched below Kage level,
except for opponents possessing extremely powerful Bloodline Limits, Jinchuriki, or extraordinary Secret Techniques.
After Sora fully recovered, Tsunade and the others arrived at Tanzaku Town.
According to Tsunade, she had worked hard taking care of him for a long time, so it was time to relax and enjoy themselves, and Tanzaku Town happened to be an excellent place for that.
Sora had stayed there for quite some time before, so he was already familiar with the place and had no objections.
"It is time to study the jutsu inside the Scroll of Seals," Sora thought.
Aside from necessary cultivation training, Tsunade spent most of her days visiting hot springs and gambling dens, occasionally resting in her room.
Meanwhile, Sora began researching the jutsu recorded in the Scroll of Seals immediately after his recovery.
After Tsunade repeatedly examined the scroll, the jutsu inside were confirmed to be genuine.
However, because they were extremely powerful Forbidden Jutsu and profound techniques, simply knowing their cultivation method did not mean one could learn them successfully.
For example, the scroll contained the First Hokage's Wood Release cultivation and execution methods.
But the problem was obvious because no one could actually learn it. Therefore, knowing the method alone was useless.
However, Sora never expected to learn Wood Release.
What he wanted were other powerful Forbidden Jutsu and profound techniques, especially Space-Time ninjutsu such as the Flying Thunder God Technique.
This technique was originally created by the Second Hokage, Senju Tobirama, yet besides him, only the Fourth Hokage, Minato Namikaze, had mastered it.
The Fourth Hokage could not have personally learned it from Tobirama because Tobirama had died long before Minato became famous.
Therefore, it was highly likely that Minato learned it by studying the cultivation method for the Flying Thunder God Technique left behind by the Second Hokage.
Since Minato Namikaze could learn it, Sora believed that he could also learn it.
If he mastered this technique, his ability to protect himself and his combat power would increase greatly.
The most likely place where the Fourth Hokage had obtained the Flying Thunder God Technique was the Scroll of Seals, which contained numerous powerful jutsu left behind by successive Hokage.
With excitement, Sora opened the scroll. As expected, the cultivation method for the Flying Thunder God Technique was recorded inside.
Not only that, but besides the method left by the Second Hokage, there was also an improved version of the Flying Thunder God Technique recorded by the Fourth Hokage.
However, the more Sora read, the more serious his expression became.
By the time he finished reading, his face had become extremely solemn.
"No wonder no one besides the Second and Fourth Hokage can independently use Space-Time ninjutsu because learning it alone is incredibly difficult and talent is absolutely essential," Sora muttered while studying the scroll.
"One must first master the Flying Thunder God marking formula, and that is only the initial stage, while the highest level, which allows a mark to be placed anywhere instantly, is even more difficult."
After reading through the technique, Sora felt overwhelmed.
The conditions required to successfully cultivate the Flying Thunder God Technique were extremely demanding.
Talent alone was not enough. One also needed a powerful body, excellent sensory abilities, and exceptional chakra control.
If a person also possessed a natural affinity with space, then learning the technique would become easier.
Beyond all of these requirements, there was still the problem of mastering the Flying Thunder God marking formula, which was unbelievably complex.
The complexity of this formula was countless times greater than the S-Rank secret technique Sora currently possessed.
Even after studying the scroll, he was not confident that he could succeed.
"This is definitely the most complicated and difficult profound technique I have ever encountered," Sora said with a headache.
He even realized that the difficulty of learning Edo Tensei could not compare to the Flying Thunder God Technique.
At that moment, Sora felt a deep sense of admiration for the Second Hokage.
Although Tobirama lacked the First Hokage's Wood Release and had no Bloodline Limit.
He created numerous revolutionary Forbidden Jutsu and profound techniques, including the Space-Time ninjutsu Flying Thunder God Technique and Edo Tensei.
Both techniques were incredibly powerful and had been created entirely from scratch.
How could Sora not admire someone capable of such genius?
"Even though it is extremely difficult, if the Second Hokage could create the Flying Thunder God Technique from nothing and the Fourth Hokage could learn and improve it, then I refuse to believe that I cannot learn it," Sora said firmly.
"After all, I do not need to invent or improve the technique because I only need to follow the cultivation method step by step."
Sora's stubborn determination was fully ignited.
Besides his necessary daily training, he devoted most of his time to cultivating the Flying Thunder God Technique.
Previously he could always ask Tsunade for guidance.
But this time he had to rely entirely on himself because even Tsunade knew nothing about the Flying Thunder God Technique.
However, the greater the difficulty, the stronger Sora's determination became.
His daily cultivation never stopped. Every day he created numerous Shadow Clones to practice the Flying Thunder God Technique.
Even with the help of Shadow Clones, however, his progress remained very slow.
If he had not used Shadow Clones to accelerate his training, Sora might not have been able to make meaningful progress even in an entire lifetime.
