Testing combinations that meet the requirements from countless basic spells and materials is a tedious task—although the overall research environment at the Magic Guide Technology Research Institute is delightful, that doesn't mean the research work itself is also light and pleasant.
Cohen has been conducting these basic tests for dozens of days now. During these days, he has tested nearly a hundred different magic materials using a dozen kinds of different magic effects—including new materials formed by mixing various magic materials. In these tests, he indeed discovered that some substances would change when stimulated by specific categories of spells, such as softening, hardening, expanding, etc. However, completely meeting the project requirements, and having a reversible process, has yet to appear.
Yet he continues performing these tests silently, recording every test result in detail.
