Before you click on the magic book to get 20x the miner, the miner was a waste. Diamonds are given priority. With 6 waves of Mimics plus 10x Carnival and Demon Eyes, you can accumulate resources in one wave. I feel that the increase is limited (mineral income after reincarnation is now doubled or even several times). You can consider switching) The resuscitation miner is a huge improvement point, and the additional purchase of items, fruits, drinks, and festivals are all relatively big improvements. The same goes for the candles. After all these are lit, only the last time is left. The value won't increase much, you can only grind it.
