那么类似这样的情况怎么样:

\documentclass{book}
\usepackage[usenames]{xcolor}
\usepackage[explicit]{titlesec}
\usepackage{lmodern}
\usepackage{lipsum}

\newlength\chapnumb
\setlength\chapnumb{4cm}

\titleformat{\chapter}[block]
{\normalfont\sffamily}{}{0pt}
{\parbox[b]{\chapnumb}{%
   \fontsize{120}{110}\selectfont\textcolor{red}{\thechapter}}%
  \parbox[b]{\dimexpr\textwidth-\chapnumb\relax}{%
    \raggedleft%
    \hfill{\textcolor{blue}{\LARGE#1}}\        \rule{\dimexpr\textwidth-\chapnumb\relax}{0.4pt}}}
\titleformat{name=\chapter,numberless}[block]
{\normalfont\sffamily}{}{0pt}
{\parbox[b]{\chapnumb}{%
   \mbox{}}%
  \parbox[b]{\dimexpr\textwidth-\chapnumb\relax}{%
    \raggedleft%
    \hfill{\textcolor{blue}{\LARGE#1}}\        \rule{\dimexpr\textwidth-\chapnumb\relax}{0.4pt}}}

\begin{document}

\chapter*{A Long Title for an Unnumbered Test Chapter}
\lipsum[4]
\chapter{Introduction}
\lipsum[4]

\end{document}
