[Japanese] What is the composition of "ねどど" in "Samurai Eating ねど"?

I checked Guangci Garden, which means "samurai eat, eat and eat."

It can be seen that eating わねど means eating べなくても, but is ねど the abbreviation of なくても? Sounds like ~ ~ ~

Then fuck Yahoo! For example, the verb "なぃけれど" plus the verb "ねど" equals ".

For example: たべけねど (たべる), せねど (する)

So when it comes to composition, it means adding a continuation word to the negative suffix ~ ~ ~ without a specific name.
