For someone like Sun Jing, an "Alchemist," the difficulty of refining elixirs far exceeded that of cultivating martial arts techniques.
Over the next two days, Sun Jing stayed by the pill furnace, hardly taking a single step away. Her eyes remained fixed on the furnace as she continuously injected strands of pure Wood Element Qi into it. Her Divine Sense also entered the furnace periodically for monitoring.
However, no matter how powerful a martial artist was, such frequent use of Spiritual Energy and Divine Sense would be hard to sustain for long periods.
So, after two days, Sun Jing felt her Qi Sea had been emptied of Spiritual Energy. Her Divine Sense was significantly depleted, leaving her exhausted both physically and mentally. She had no choice but to entrust the task of watching and monitoring the furnace to Fang Bai and retreat to the side for recovery, aiming to quickly replenish her depleted Divine Sense.
