"Junior appreciates Senior's kind intentions, but the matter of my Dragon Chant Physique is my own concern, so I need not trouble Senior with it."
Seeing this, Xin Ruyin struggled and hesitated for a moment before politely declining Fang Yu's offer.
She did not dare entrust the matter of her Dragon Chant Physique to a strange Foundation Establishment cultivator. That would be no different from handing her life over to him.
"Since that is the case, how about we make another deal?"
After hearing Xin Ruyin's words, Fang Yu was neither angry nor surprised. Instead, he continued speaking.
"Another deal? What kind of formation does Senior wish this junior to set up?"
Hearing this, Xin Ruyin furrowed her delicate brows. She already understood what Fang Yu meant.
"That's right. A formation to protect a cave abode, as well as an illusion formation."
Fang Yu nodded with a smile and stated his requirements.
After reviewing Yellow Maple Valley's information on formations, Fang Yu discovered that illusion formations could likely temper and refine mental power as well, helping him break through to the ninth stage of the physical body, the Spirit Communication Realm, sooner.
In the The Great Primordial World, one could only construct formations after reaching the fifth level of the Mystical Ability Realm, the Heaven and Human Realm, and connecting yin and yang. Only then could one strengthen one's internal organs, extend one's lifespan, and refine spiritual artifacts and treasure artifacts. All of this required advancing to the Heaven and Human Realm first.
Even Fang Qingxue could not do so yet.
Yet in the Mortal World, even a cultivator like Xin Ruyin, who had not even reached the tenth level of Qi Refinement, could set up formations.
This showed that the Mortal World still had quite a few merits worth
