After obtaining the Heart Sword, Lin Changsheng returned to his reclusive lifestyle. Each day, apart from cultivating, he would hide in his small courtyard, practicing the art of controlling his Flying Sword.

He attached his Mind Power to the Heart Sword, repeatedly familiarizing himself with the feeling of becoming one with the sword. At the same time, he began to attempt controlling more Flying Swords simultaneously.

From the initial five swords, to ten, and then twenty... he discovered that with his current level of Mind Power, he could control up to thirty-six Flying Swords at once, forming a rudimentary "Heavenly Astral Sword Formation."

Although most of these Flying Swords, aside from the Heart Sword, were of inferior quality, under his meticulous Mind Power control, they could still unleash terrifying destructive power.
