You asked why he had to do this?
The reason was simple. After these two days of in-depth research, he had confirmed that if his "Shadow Clone Technique" was only at lv5, it would not be enough to let him complete the development of the "Shuriken Shadow Clone Technique."
In that case, developing the "Shadow Sword Technique" on that foundation was even further out of the question.
If he wanted to accomplish that, he first had to raise the level of his "Shadow Clone Technique."
Therefore, a certain amount of investment was necessary.
In addition, there was the issue of coordinating it with "Wind Release: Wind Wings."
Previously, Qian had thought the reason he could not directly create shadow clones with Chakra Wings during flight was that the level of "Wind Release: Wind Wings" was not high enough.
But after long testing, he discovered that this was only a secondary reason.
The most important reason was still that his training in the "Shadow Clone Technique" was not adequate, which was why it could not perfectly replicate his current physical state.
Therefore, no matter which situation it was, he had to raise the level of his "Shadow Clone Technique" as soon as possible.
And with the investment of these fifteen thousand points of chakra, plus the passive improvement from training other skills, his "Shadow Clone Technique" should be able to gain 100 points of Proficiency every day from now on.
At that rate, in only about forty days, his "Shadow Clone Technique" would successfully advance.

Not only that, as the level of his "Shadow Clone Technique" increased, he
