Each train followed its own route without interfering with the others. However, once a route was changed, it was fine if the change was correct and caused no conflict. But if the route was changed incorrectly and the paths of two trains collided, the final result would naturally be the two trains crashing into each other and exploding.
Therefore, if Mirai made a mistake while modifying the route, the outcome would not be as disastrous as a train collision, but there was still the possibility of a small explosion caused by mental instability.
This seemed like a thankless task. After all, even if the trajectory of the Big Ball Rasengan was altered and its attack power successfully enhanced, no matter how powerful it became, it probably still would not surpass Mirai's sword.
Mirai's sword was ferocious, but it consumed a great deal of mental energy. Although the expanded Rasengan's skill and offensive power might be somewhat inferior to the Meteor Star Godslayer sword technique used through the Divine Wind Sword, its mental energy consumption was far lower.
Moreover, God-Extinguishing Meteor had to be used with the blessing of the Divine Wind Sword for its power to rival the techniques of a high-level S-rank ninja. Without the Divine Wind Sword, the power of Meteor Star God-Extinguishing would be greatly reduced. Besides, as the saying went, having more skills was better than being caught helpless.
Furthermore, while expanding the range of applications for the Spiral Pill, Mirai could also practice controlling his spiritual power. It was, in a sense, killing two birds with one stone.
After determining the general direction, Mirai began studying how to alter the trajectory in order to greatly increase its power.
An ellipse? Internal chaos?
No matter what kind of circular pattern or spiral shape Mirai experimented with,
