Testing, Su Hua's Astonishment

"What is this Grand Immortal Tea? Just a type of tea leaves, yet it possesses celestial grades?"

Gu Lan felt mildly astonished in her heart.

It's worth noting that the ordinary medicinal herbs used for alchemy in the mortal realm, at most, reach the Imperial Grade level.

Celestial-grade divine medicines, such as the Soul Returning Pill and Resurrection Pill he had obtained before, are all miraculous products refined by the changes of heaven and earth.

At this moment, the system rewarded a type of tea, claiming it to be a celestial-grade treasure.

Gu Lan was somewhat surprised.

What kind of tea leaves could be rated as celestial-grade?

Could drinking it make mortals ascend to immortality, or even let celestial-grade beings ascend during broad daylight?

Su Hua didn't notice Gu Lan's distraction and continued to inquire, "So, does this mean you have reached the third realm of tea mastery?"
