After reaching the venerable realm and above, it was increasingly difficult to raise one's cultivation. Ling Chuxi had always been looking for a shortcut to cultivation. The Great Transformation Heart Sutra, the primordial spirit cultivation technique, the spiritual pills, and the heaven seeking tower of the great Dao were undoubtedly all shortcuts for cultivation. However, the improvement of one's strength ultimately could not be separated from the improvement of one's venerate origin Qi, which was the foundation.
Although the great Dao heaven seeking tower could help her comprehend the nomological laws of the venerable realm more easily, if her vital Qi was strong enough, her cultivation level would still be unable to increase. However, no matter how abundant the spiritual Qi of heaven and earth in the venerable realm was, it was still limited. Even with the primordial spirit cultivation technique and the help of spiritual pills, her vital Qi improvement was still limited.
