How to get post from all custom post_type multisite to the main site with pagination ordered by date?

Question

Currently this is my WordPress Multisite:

Main site

-Sub Site

-Sub Site

-Sub Site

-Sub Site

and this is the example code for getting all post from multisite :

foreach( $blog_ids as $id ) {

    switch_to_blog( $id['blog_id'] );

    $args = array('post_type' => 'events', 'posts_per_page' => 2,'paged' => $paged,
      $meta_query = 
        array(
          'relation' => 'OR',
          array(
            'key' => 'event_date',
            'value' => date('Ymd'),
            'type' => 'DATE',
            'compare' => '>='
          ),
          array(
            'key' => 'event_second_date',
            'value' => date('Ymd'),
            'type' => 'DATE',
            'compare' => '>='
          ),
        ),
        'orderby' => 'date',
        'value' => date('Ymd'),
        'orderby' => 'meta_value_num',
            'meta_key' => 'event_date',
            'order' => 'ASC',
            'meta_query' => $meta_query,
    );
    $query = new WP_Query( $args );

    if( $query->have_posts() ) : 
        while( $query->have_posts() : $query->the_post();

            // post template goes here

        endwhile;
    endif;
    wp_reset_postdata();

    restore_current_blog();
}

and the code above produce :

• Post 1 (From Sub Site 1)
• Post 2 (From Sub Site 1)
• Post 1 (From Sub Site 2)
• Post 2 (From Sub Site 2)
• Post 1 (From Sub Site 3)
• Post 2 (From Sub Site 3)
• Post 1 (From Sub Site 4)
• Post 2 (From Sub Site 4)

And for the next page it produce this :

• Post 3 (From Sub Site 1)
• Post 4 (From Sub Site 1)
• Post 3 (From Sub Site 2)
• Post 4 (From Sub Site 2)
• Post 3 (From Sub Site 3)
• Post 4 (From Sub Site 3)
• Post 3 (From Sub Site 4)
• Post 4 (From Sub Site 4)

Since I'm using 'posts_per_page' = 2, what I really want is showing post ordered by date from all multisite, like this :

• Post 1 (Fetch from the latest event date regardless from which Sub Site this come from )
• Post 2 (Fetch from the latest event date regardless from which Sub Site this come from )

And next page :

• Post 3 (Fetch from the latest event date regardless from which Sub Site this come from )
• Post 4 (Fetch from the latest event date regardless from which Sub Site this come from )

What is the best solution to manage this scenario? Since I want to paginate the posts.
