Nurturing a sword was something that required a lot of effort for sect disciples.
The northern sword immortal sect specialized in the sword nurturing technique. Normally, after becoming an inner sect disciple, they would nurture their sword and hang a sword at their waist at all times. This wasn't to show off, but rather, at 11:30 pm, the person who nurtured the sword had to feed it with fresh blood and spiritual power.
If he did not nurture the sword for one day, all his efforts would be wasted. If he did not nurture the sword for three days, the sword would lose its spirituality with the person who nurtured it, and it would be impossible for him to nurture the sword.
"After you've successfully nurtured the sword, the death energy in its body will naturally not harm you." The Supreme elder told Li Tian some things in detail.
