How could he possibly fail to learn this?
Si Sui could not fathom it no matter how he thought about it, sinking into profound confusion.
After creating this teaching method back then, he had specifically found a mountain forest in the mortal world, awakened a monkey's spiritual intelligence, and used it as a teaching model.
The result was that even the monkey had learned it.
So how could Lu Yang fail to learn it?
In the field of education, Si Sui had always been exceedingly proud. There were almost no students he could not teach, so his first instinct was always to suspect that the problem lay with someone else.
So where was the problem?
With that thought, Si Sui carefully examined Lu Yang's cultivation. Wisdom Light blazed in his eyes as countless Talismans intertwined within them, rapidly deriving the answer.
And so, another month passed.
".So that's how it is."
At last, Si Sui let out a long breath. Looking at Lu Yang, who had already gone somewhat numb, he revealed a smile of relief. "As expected, it wasn't my problem."
Then, he gave his answer:
"Fellow Daoist, your spirit has been innately incompatible with essence and qi, so no matter how many times you try, you cannot accomplish the most basic [Unity of Essence, qi, and Spirit]."
As he spoke, even Si Sui found it strange. "Generally speaking, this only happens when someone at a low realm seizes another's body. Yet Fellow Daoist's cultivation is already so high, and both your Dharma Body and dharma power have transformed several times. In theory, this problem should not exist. It seems to be something more fundamental..."
The more Si Sui thought about it, the stranger it seemed.
Only after a long while did his brow finally relax again. He smiled.
