"Huh? Wind Release unlocked too—when did I experience Stillness?"
As soon as Akaseki entered the game, he discovered another option among the available deck templates: "Wind Release."
Judging by the previous pattern, he needed to unlock all six transformations before he could unlock a deck.
Indeed, ever since his "talent for Wind Release chakra transformation" had awakened, Akaseki had used every opportunity for immersion to stimulate Wind Release—
First, since Wind Release had only just awakened, stimulation produced the best results; second, Wind Release countered poison mist, which was exactly what Akaseki needed now!
However—
"Joy, Anger, Sorrow, and Happiness" were easy. Regardless of his progress, all four unlocked within an hour, letting him see their names.
"Urgency" was fairly easy too—
By the second hour, Akaseki had been desperate to find out how it ended!
The problem was "Stillness." He had never managed to trigger it.
Earlier, Akaseki had not realized when he had reached the point where "there was no greater sorrow than a deadened heart," either.
Then it suddenly dawned on him—
It must have been when everyone was making dumplings, and Akaseki had gone completely numb!
That had also counted as Stillness.
With that, all six Wind Release chakra transformations had unlocked, and he could now choose the "Wind Release" deck in Sacred Spire.
These games looked like nothing more than games, but they were actually very effective at "teaching through entertainment."
The Wind Release deck started with two basic cards for each of the six transformations—
After that, he had to earn rewards from the various challenges as he climbed the spire, adding cards, removing cards, and upgrading cards—
Finally, when the run was evaluated, the completed deck could become a "ninjutsu," provided it was strong enough.
This time, Akaseki was not climbing the spire
