Ikaris stiffened at first, uncomfortable with Danchun being so close to him. Her chest regularly pressed against his back or arm as she corrected his posture and he found it hard to focus on anything else.
Her feminine scent was also a nuisance. His mutation into a Crawling-Thrall had caused his sense of smell to be much more sensitive than before and at this distance her fragrance intoxicated him, causing a physiological reaction in him that he could have done without.
When the breathing of the boy quickened, Danchun realized right off the bat how much she was affecting him and smartly adjusted her position, avoiding the slightest body contact beyond what was necessary. Because she thought she was dealing with a mere 14 or 15 year old, she chalked up his reaction to immaturity or inexperience. If she had known that her Lord was in fact an adult, her attitude would probably have been very different.
Sorry for the late chapter, I had to edit chapter 70 because of an inconsistency that was mentioned to me (the fact that the villagers from different countries and worlds all understood him).
For those who are lazy to reread this chapter, he uses an artificial Bloodspark provided in the Welcome Pack. A Sorcerer charges it using the Language Spell a number of times and Ikaris just has to connect his mind to it while touching it as he does with his Divine Spark to trigger it on the targets of his choice.
