Wang Sheng had never really used it before, just cultivating the "Lifeless Vacuum Sensing Chapter" and then letting the progress bar fill up.
This method was actually something he thought of on the spur of the moment yesterday.
When he used Divine Thought to probe Liu Jian'an's strength, he found that his understanding of Qi Blood Martial Arts had deepened further, and he could even imitate some aspects of it, which gave him this idea.
Although his Spirit World was still immature, accomplishing such a simple task was still possible.
Especially after reaching the stage of "Refining Qi into God", doing these things became even easier.
It would perhaps be unmanageable with many people, but with one or two, or even a dozen, it was quite effortless.
Yet, the effectiveness of this method was beyond what Wang Sheng had expected.
Initially, this was also done in an experimental nature; even if it could not succeed, Wang Sheng had ways to make Liu Jian'an become a Grandmaster.
