It explains that: The CE using as a fodder also carries with it all the EXP it had gotten so far.

For example: A limited break Black Key CE will yields 5 times amount of EXP comparing to one Black Key CE. A fodder lvl 20 CE will bring all its EXP to a lvl 1 CE and immediately makes the lvl 1 to lvl 20.

Meaning: a high lvl CE is cost a lot QP to grow. So you can utilize this and make a lot of lvl 20 CE (1-2 stars CE, which can be found a lot through Friend Point Gacha). Then have the high lvl CE grow using these lvl 20 CEs. Although this method take time, it's very effective to grow these high lvl CE.
