Is this sentence correct:

1-My brothers are wealthy and so are yours, but the wealth of your brother was no earned in the same way as that of mine. (as the wealth of my brothers)

Is this sentence correct:

It's possible, but this is more natural:

...but your brother's wealth was not earned in the same way as my brother's.
