Chapter 374
The primary function of the Universal Ninjutsu Enhancement Card is to improve the effects of the same type of ninjutsu cards!
In other words, Haruto Saito's card can enhance any S-rank forbidden technique he currently possesses. For example, if he has mastered the S-rank space-time ninjutsu, the Flying Thunder God Technique, he can use this card to upgrade it!
If he consumes this S-rank Universal Ninjutsu Enhancement Card and applies it to the Flying Thunder God Technique, it would be equivalent to eating a second Flying Thunder God Ninjutsu Card! The effects of the Flying Thunder God Technique he has mastered will then double according to the card consumption rule!
The term "universal" means it can substitute for any other card. The S-rank Universal Ninjutsu Card has another function—it can transform into any A-rank ninjutsu card, including forbidden techniques! It could be an ability Haruto already possesses or one he has yet to acquire!
This put Haruto in a dilemma.
His first instinct was to enhance the Flying Thunder God Technique! This ability was crucial, and it would never be a wrong choice to strengthen it!
But!
Some powerful A-rank forbidden techniques also tempted him!
For example, the enhanced version of the Rasengan—the Giant Rasengan—was still an A-rank technique rather than an S-rank one! The Giant Rasengan had far greater destructive power than the standard Rasengan!
There were also secret techniques unique to certain clans, such as the Shadow Imitation Technique, the Multi-Size Technique, and the Puppet Mastery from the Hidden Sand Village of the Land of Wind, all of which were A-rank!
The current effectiveness of the Flying Thunder God Technique was already sufficient for Haruto.
