In these twenty days, the coordination between Qin Gengyun and Liu Su has become increasingly seamless. Previously, it took an entire two-hour period to absorb one piece of Spirit Marrow, increasing cultivation by 7 points.
They would cultivate for six two-hour periods each day, gaining a growth of 42 points.
Now, they only need half a two-hour period to absorb one piece of Spirit Marrow. By cultivating for five two-hour periods and absorbing ten pieces of Spirit Marrow a day, they can increase by 70 points daily.
The growth has become equivalent to that achieved with his wife.
It could be said that both his wife and sister-in-law are his wings, helping him rapidly progress to the Eighth Layer of Qi Cultivation.
However, ever since the house-warming banquet that day, his wife has been occasionally unwell.
Although she never showed any sign of pain in front of him, Qin Gengyun could still sense that his wife's body must have a problem.
