I searched around here and did not find anything accurate to what I wanted. I would like to know other ways to increase the decrease in the space between underline and words as well as in this MWE below using soul package.
\documentclass{article}
\usepackage{soul}
\setul{10ex}{}
\begin{document}
BIRD BIRD \ul{JJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJ \\ JJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJ}
\end{document}


\setul{xxx}{}, where you can set any length instead ofxxx. The option to modify the distance between the lines of text is\begin{spacing}{yyy}, where you can set any number instead ofyyy. Sorry, I don't know other methods. – CarLaTeX Feb 25 '19 at 05:51
