Yan Wei and Zhou Boxiong did not linger any longer and soon left the Ziyuan Villa.
As for Tang Rao, he sat quietly on the bed with his legs crossed.
Now that the Spiritual Energy in his Dantian was completely overflowing, he was ready to step into the Qi Gathering Phase.
One hundred units of Spiritual Energy are needed to begin Qi Gathering, and Tang Rao already has over five thousand units within his abdomen, which is certainly terrifying.
Gathering Qi could be said to be easy, easy to an unsurpassable degree; or it could be said to be difficult, so difficult that Tang Rao had no clue whatsoever.
Gathering Qi with one hundred units of Spiritual Energy was clear to Tang Rao; however, from five thousand units, Tang Rao had absolutely no experience.
Of course, he could still use one hundred units of Spiritual Energy for the initial Qi Gathering and use the remaining energy to directly enter the later stages of Qi Gathering.
But doing so would be incredibly foolish.
