For nearly half a month, Richard had stayed in a guesthouse in "Linghua Town," not leaving as he continuously tested various ideas regarding the energy storage container.
But the results were not very good, as he eliminated many incorrect ideas without making much noticeable progress.
He tried using a variety of materials to create energy storage containers, but most completely failed to store free energy elements, and the few that could store them had many flaws.
Such as short storage times, unstable performance, and low conversion efficiency.
After half a month, Richard had to leave "Linghua Town" because he had nearly exhausted all the local materials he could test, and he needed more, more precious, and rarer materials for further testing.
