Teaching wasn't difficult for Richard given his level of knowledge, and he easily finished a morning-long lecture with a still keen interest.
After the class, Richard carried his notebook back to Jolod's laboratory and took out the Dragon Blood he had obtained from Yelena.
Since he was substituting, Richard didn't have his own laboratory in the Central Black Tower and had to temporarily use Jolod's.
However, Jolod's laboratory was one of the best in the Black Tower Wizard Academy, and Richard was quite familiar with it, so he could use the various equipment smoothly—in contrast, the equipment in his own Wizard Tower felt somewhat inadequate.
"No, a workman must first sharpen his tools. I have to upgrade the equipment in my laboratory when I return. The Commerce has made so much Magic Essence, it's about time to use some."
After reflecting on the laboratory, Richard took out Jolod's Alchemy Centrifuge and prepared to process the Dragon Blood he held into a serum.
