For alchemy, the higher the upper limit of Confusion, the faster the money will be researched. The higher the upper limit of Fei Gang, the shorter the time to obtain money. The upper limit is 100. Try to check as many levels as possible within five minutes and then ascend the level. Fei Gang seems to increase by a percentage each time you ascend the level. If you are confused, you need to clear more levels to increase the amount. I am now confused at 300,000, and the alchemy will increase very slowly after basically reaching 100 million.

And I feel like there is no benefit from hanging up. Is it my problem?

It seems I still brushed too little.
