"Hypersonic speed, that's enough to escape."
Lin Zheyu mused to himself.
The Immortal from the Observatory he encountered earlier, the fastest flying sword, was only close to four times the speed of sound.
Even if the opponent possessed stronger magical treasures, as long as Lin Zheyu ran fast enough, if the magical treasure's speed didn't exceed hypersonic speed, it couldn't catch up to him.
If all else failed, under full exertion, he might burst out at an astounding speed comparable to six times the speed of sound.
However, at that point, Lin Zheyu would be completely unable to see the surrounding environment, unable to distinguish between east, west, south, and north, and could only charge ahead blindly.
In that situation, one wrong move, colliding with a solid object, might cost him his life.
Unless there's no way out, Lin Zheyu absolutely did not want to experience that feeling.
