[Defeat your future self from fifty years later. Time remaining: 24 years 350 days.]0

Huh?0

Once again, a week had vanished in the blink of an eye. By my perception, not even twenty minutes had passed since the start of the trial, but two weeks had already slipped away.0

Compared to the twenty-five years I had been granted, it was a brief span. However, comparing the rate of loss to how long I had been here, it was a costly mistake. In a situation where I needed to strengthen at more than double the rate I would normally, I had already lost two weeks.0

Thankfully, this last defeat didn’t leave me feeling regretful. What I had seen was worth the seven days—the way in which my opponent had swung his axe. 0

Though I hadn’t seen every detail with perfect clarity, he hadn’t executed a particularly complex strike. Despite that, the fact that I had spotted anything at all gave me a huge sense of relief. I knew now that he had used the Heart Sword, and though we shared the technique, it existed on a level far beyond my own. I concentrated deeply, committing the strike’s trajectory to memory with utmost clarity so that it wouldn’t fade from my mind. 0

However, that wasn’t my only revelation. Upon awakening, I was truly startled by the complete absence of any backlash from using Thunderbird. 0

If that continues to be the case, maybe I should use it more.0

The other me could certainly use Thunderbird as well, and his would no doubt be stronger. Also, despite my reckless charge with Thunderbird active, he hadn’t activated his own. In hindsight, that made sense....0
