Without a cultivation partner, he could not break through at all.
To him, a cultivation partner was like a key that he could not do without. It didn't need to be made of precious materials, but without this key, he could not open the door to the next realm.
It was just that before, he had always broken through with the help of cultivation partners and had never noticed this issue.
After obtaining the powerful Natural Law Spiritual Qi, the help from his cultivation partners became insignificant, and they were only occasionally useful for adjusting his mentality. If he really wanted to rely on them for a breakthrough, both parties would need to have eternal life.
Even now, with Luo Han, who had broken through to the Golden Core Realm, their combined cultivation could only increase their cultivation points by eight at a time.
Even with the help of the Pink Peach Blossom Scripture and the Gold Wind Jade Dew Pill, the most they could achieve was about twenty points per session.
