Teacher, you underestimate me too much.

Walking inside the empty cave, Lucas took out many utensils that were required to make a potion. Beakers, flasks, stand holders, and burners were among the few things that he placed and set up a small potion workshop for himself. 

After setting up the workshop, Lucas ensured that the cave was well ventilated, and later when it was done, he took out the ingredients from his ring and started concocting the potion.

Few hours passed.

Lucas was done concocting the potion. The procedure to do such a thing, if Lith or any Earthling were to look at it, they would definitely say that concocting a potion looked like doing a chemical reaction in a chemistry lab back on Earth. The ingredients used were all in grams and the utensils were also small, unlike the ones used for refining pills.
