When reaching the Integration Phase, breaking through one layer required nearly five times more resources!
This was still the time taken for Su Xing to advance his cultivation technique to the Heaven Rank Myriad Flames Technique, coupled with the dual support of possessing a fifth-grade Minor Spirit Gathering Array.
"For an ordinary cultivator, wanting to cultivate from the first layer of the Integration Phase to the second layer, even in a place rich in Spiritual Energy, and using Spirit Stones and other resources, it would probably take at least eighty years, or even more than a hundred years!"
"The path of cultivation indeed becomes increasingly difficult as one progresses upward!"
Su Xing calculated slightly. If he did not rely on Spiritual Liquid and Spirit Stones, but merely cultivated in the Spirit Field Cave, it would probably take thirty to fifty years to break through one minor realm.
