One Technique to Suppress the Heavens

Legend says that above the nine heavens lies a road to immortality and a supreme immortal sect. Step through its gates and you can live forever. But if immortality is what cultivators seek, why do they become a blight in Heaven's eyes? Humans have magic arts, immortals have immortal arts, and Heaven has its own arts. Heaven's arts suppress all others. They are the origin of every art, and all the world's methods began with them. Su Ye, a lowly being who transmigrated into this world and nearly became a sacrificial offering to the immortals of the nine heavens, will have to tread across the realm of immortals. How will he break through the immortal sect's gates?
