When Xia Yan used the Flying Thunder God Technique, Hashirama Senju had already decided that this battle could be taken up a level.
That was also why he had used a Wood Clone. Although he did not know how to use the Flying Thunder God Technique, he understood it.
Besides, his younger brother had invented the Flying Thunder God Technique. How could his brother possibly not have shared this Ninjutsu with him for study and discussion?
The reason Hashirama Senju had not learned it was simple: his fighting style had no need for Flying Thunder God's assistance.
His defenses and perception really gave him no reason to fear Flying Thunder God's spatial jumps. To put it bluntly, even a surprise attack using Flying Thunder God would not hurt him too badly.
He could even vaguely judge the caster's direction and movements the instant Flying Thunder God activated, then take countermeasures.
Of course, that also had something to do with how Tobirama Senju used Flying Thunder God. The moment he saw a Kunai flying toward him, he more or less knew what was coming.
Xia Yan's approach was extremely clever. After all, Xia Yan was a Wood Release user just like him.
This kid used Flying Thunder God in conjunction with Wood Release, burying Wood Release seeds underground and forming Flying Thunder God Marks on them.
Such an application could be called revolutionary-perhaps even something no one had ever done before or would ever do again.
Neither Flying Thunder God nor Wood Release was something one could easily learn or obtain.
By mastering both powers at once, Xia Yan had truly reached a height that others might never attain in their entire lives.
But however flashy Xia Yan's methods were, every Ninjutsu ultimately depended on its essential activation process-activating Chakra.
