  In a given path with multiple branches, in principle, it can be expected that
there are some fork points, where one branch is bifurcated into different
branches, or various branches converge into one or several branches. In this
paper, it is showed that if there is a web formed by such branches in a given
field space, in which each branch can be responsible for a period of slow roll
inflation, a multiverse separated by domain wall network will come into being,
some of which might corresponds to our observable universe. We discuss this
scenario and show possible observations of a given observer at late time.
