As the seed sank into the soil, Lex cracked his neck and concentrated his focus. There was no room for error now. Fortunately, his instincts somehow synchronized with the information he had read about growing the tree, and began guiding him perfectly.
He channeled his spiritual energy into countless little strings and trickled them into the soil, slowly snaking them through the dirt to the sinking seed.
A barrier, formerly invisible, suddenly appeared covering the skin of the seed, filled with various unusual characters. The barrier was the Void shell of the seed, a protective shield to save the seed from the cosmic radiation of space. It would only break under very specific circumstances, so that the seed would have the optimal conditions for its growth when it eventually breaks.
Lex was not breaking the barrier, but diffusing the unique energy that it was made of into the seed itself.
