    So this is the hook for node view later.
function hook_node_view_alter(&$build) {
 // Code
}

To use that hook...
/**
 * Implements hook_node_view_alter().
 */
function my_module_node_view_alter(&$build) {
 // Example of how to create a variable.
 $vid = $build['body']['#object']['vid’];
 // Create a placeholder for original vid value.
 $build['body']['#object']['original_vid'] = $vid;
 // Reset the value of vid.
 $build['body']['#object']['vid’] = NEW_VALUE;
}
