章 1888: Yunku Abode!

"Higher-quality spacetime crystals…" Lin Feng muttered softly.

Lin Feng muttered softly.

He was thinking quietly. Ruler Starfield did not disturb Lin Feng. He knew very well that Lin Feng had to consider it for himself now.

In reality, Lin Feng had also sensed it himself. He had used 33 spacetime crystals, but they were all just ordinary spacetime crystals. They only made his foundation more stable.

It was equivalent to him "sorting out" the principle of spacetime again, making the principle of spacetime completely his. No one could take it away.

Even if he had to do it all over again, he was confident that he could comprehend the principle of spacetime!

However, how could Lin Feng improve the principle of spacetime like this? At the very least, those ordinary spacetime crystals would probably not be very effective anymore. According to Ruler Starfield, after reaching a certain level, ordinary spacetime crystals would be useless.
