Hendrix stood at a spot on the front of the platform. He looked down from the top and watched the entire open ground. His gaze swept across the arena, looking at the place where a third of the competitors had been eliminated. 

"Congratulations to all of you who are still standing. You have more or less successfully passed the test for the first round. However, the round is not over," Hendrix said with a smile, 

"Alchemy is a complex art. Some alchemists may have concocted a pill that might look like a high-purity pill. However, they might not have the desired healing properties. Hence, we will check whether the pill has achieved the required level.

The slightly hoarse voice of Hendrix slowly sounded in everyone's ears, "Now, can all the competitors please search for a green colored button located at the bottom left corner of your jade table,"
