After cultivating for a long time, Qin Yi discovered that the Veil of Time Illusion Space was not as omnipotent as he had originally imagined. It still had its limits.
Because—
This space was not innate; he had to cast a spell to create the difference in time flow. With his current ability, one casting could last around three days. At a ratio of one to three hundred, that meant two and a half years inside, after which he had to do it again.
Two and a half years of practice... Hm... In the past, that would have been enough for him to leap across an entire major realm. But now, it was not enough. He might not even advance a single minor level.
At his current level of cultivation, other cultivators often required a retreat measured in centuries. And those centuries were not split into segments; more often than not, a single meditation session required a hundred years.
If it was divided into segments, the results would be much, much worse.
It was like a mortal getting a full eight hours of sleep at once, versus sleeping intermittently in ten-minute stretches. The effects were different, and the latter could even leave one utterly miserable.
Qin Yi might not need an absurd hundred years, but he definitely needed more than two and a half. Carrying it out in such broken intervals was not as bug-like as he had first imagined.
At the very least, it was unsuitable for raising his cultivation.
At most, he could raise it one or two levels and fully cultivate the Qian Yuan Third Layer. Once he reached the threshold of breaking into the middle stage, he would have to stop. It was not suitable to rely on such segmented periods to break through a barrier.
