Trial And Error!

Drog took the Yi grass into his right hand and the bowl that was sitting on the edge of the table into his left. He tossed the Yi grass into the bowl and took the small cudgel which was also sitting on the table into his freed up hand. Using the cudgel, he smashed the Yi grass and stirred it.

"The first stage is complete," Drog thought. "Now for the second stage." He walked up to the cauldron. Using his fire Qi, he created the flame below the cauldron and waited for a few minutes, until the cauldron started to slightly shake. "The second stage is now complete."

Drog walked up to the table. From it, he took the Tchi herb and the bowl of Yi grass. He returned to the cauldron and tossed the Tchi herb inside the cauldron. Following which, he slightly increased the intensity of the flame and poured in the smashed Yi grass.

Drog kept the intensity of the flame as it was, and just waited. He waited for fifteen minutes before gradually lowering the intensity of the flame until extinguishing it. He looked down into the cauldron and saw a brown liquid inside it. "The third stage is now complete, time for the fourth one – cleansing."

Drog extended his right arm and pointed it at the liquid. He used his fire Qi, and the liquid after some time took a lighter shade.

"Now for the last stage," Drog thought. He smacked the cauldron on the side with his palm. The liquid shot up into the air. He separated the liquid into ten parts and used both fire and wood Qi on them. The ten parts solidified and fell into the palm of his hand. He looked down at them.

"Out of the ten you made, the worst one is of 95% effectivity and the best one is of 98% effectivity," Liu Ri said.

"Not good enough," Drog said as he crushed the pills in the palm of his hand. He walked up to table and took out another Yi grass and Tchi herb from his pendant. He took the Yi grass into his right hand and the bowl into his left. He tossed the Yi grass into the bowl and took the cudgel. Using the cudgel, he smashed the Yi grass and stirred it.

Drog crushed the pills in the palm of his hand again. He walked up to the table and took out another Yi grass and Tchi herb from his pendant. He took the Yi grass into his right hand and the bowl into his left. He tossed the Yi grass into the bowl and took the cudgel into his freed up hand. Using the cudgel, he smashed the Yi grass and stirred it.

"Out of the ten you made, the worst one is of 99% effectivity and the best one is also of 99% effectivity," Liu Ri said.

Drog crushed the pills and walked up to the table. He concocted another batch of pills and looked down at them.

"Out of the ten you made, the worst one is 99% effectivity and the best one is also of 100% effectivity," Liu Ri said. "Are you ready to learn my recipe now?"

Drog smiled. "Yes. Now I am ready," he said as he stored the pills that were of 100% effectivity into his pendant. There were seven such pills.
