Lin Feng returned to the Vigil Domain. Choosing planets was a minor matter. There were many people around just now, and time was limited. He had yet to study the mysterious pearl properly.
Now that he had returned to his residence and had time, he took out the fist-sized pearl again.
The pearl was fused from the four pearls, forming dense and very complicated patterns. They appeared vaguely related to the Law of Space. Lin Feng used the Law of Space to envelop the pearl, then studied the patterns on the pearl with all he had.
Time passed slowly. One day, two days, three days…
The patterns on the pearl were simply profound. At least, Lin Feng had not comprehended anything in the universe previously. Hence, after returning to his residence this time, he could study it for a long time.
