Lin Yuan was currently using his fingers to rub his temples while he was in deep thought. For the past five days, he had been sleeping for only five hours a day on average. The rest of the time would be basically used to enhance the Jasmine Lily, and it was truly exhausting for Lin Yuan. During the enhancement, Lin Yuan would need to constantly circulate the spiritual power within his body.
In order to be able to circulate spiritual power like this, Lin Yuan would need at least five hours of sleep to compensate for the exhaustion. Of course, this was because of the bowl of Silver Stamen Gold Luster Cassia nectar had consumed previously as it had cleansed the impurities in his body. If Lin Yuan tried to enhance such a fey before consuming the bowl of Silver Stamen Gold Luster Cassia nectar, his body wouldn't have been able to take it.
