Under normal circumstances, the temperature of the fire spiritual energy was equivalent to the spiritual root value. The higher the spiritual root value, the higher the temperature.
Song Qingfeng's root value had reached 91 points, but her furnace did not explode when she was refining pills. However, Dong Xi's furnace exploded when she was only in her 70s?
The master and disciple were also very confused. Master Lingxu had a faint guess in his heart that perhaps this was related to Dong Xi's physique.
Thinking of this, Lingxu felt relieved and said with a smile, "This is considered a good thing, right? This means that this little disciple was born to be an alchemist!"
Song Qingfeng also agreed with his master.
Song Qingfeng continued, "Master, I lent the Heavenly Mountain Cauldron to Junior Sister. Can you guess how many pills she made in the first batch? What grade did she make?"
