บท 1788: Successful pill refinement (1)

In the room.

Bai Yan's entire heart and soul were immersed in refining the pill and she did not notice the rustling of the battle outside the courtyard.

Her gaze was very focused and did not move away from the alchemy furnace.

BOOM!

Suddenly, an extremely loud collision sound came from the pill furnace, as if something was trying to break out of the pill furnace.

Bai Yan's expression became more and more restrained, but the flame in her palm was gradually shrinking.

It was also at this moment that she looked up at the roof, quietly waiting for the heavenly lightning to fall.

However, after a long time, the expected heavenly lightning did not appear, which also made Bai Yan frown slightly.

"This domain is a space created by an Overlord, so the lightning can't enter this space? Otherwise, it would be impossible for there to be no heavenly lightning before I succeed in refining the pill."
