The accelerator is a scam, with low output and low efficiency.

For your reference

Anything with a diagonal line can be sold. Tesla is of little use, so there’s no need to rush to save it. Try to synthesize things in the same synthesis chain as high-level as possible before taking care of other things, otherwise the endgame will be very empty. Don’t sell items from treasure chests (especially blue boxes) easily. Many commonly used production tools can only be obtained from treasure chests. If you encounter an endgame, you can consider buying them from the canteen (chalk outlines and bucket handles are OK, herbs, cartons, Threaded seeds are not recommended, too expensive). In the early stage, you can focus on upgrading production tools (toolboxes, sites, etc.), otherwise the production capacity cannot keep up and it will be difficult to take charge of the chessboard activities. Remember to save a vase box too, it will be of great use. Finally, according to the task requirements, you can consider selling things that are not needed temporarily (provided that they are easy to obtain).
