Money is a good thing.
When Zhao Yi received the one million yuan prize money, his mood became very pleasant.
In the past month, his income had decreased significantly.
First of all, the income from the Rubik's Cube calculator had declined. After the mass registration and use of the calculator, both domestically and abroad, the number of new registered users per day was limited.
This is, after all, just a calculator, and tool software sales are limited in the long run.
Since the disclosure of the 'Effective and Irrelevant Carry Filtering Method,' some companies have developed similar calculators, and 'flawed versions' or 'imperfect Rubik's Cube calculators' can already be found online.
