Child theme css stylesheet doesn't react

Hello,

I made a child theme with Orbisius Child Theme Creator plugin.
The function.php was empty. and from what I saw at WordPress, I put:

add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
function theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );

}

My css.stylesheet was made by the plugin. I just added some commands..

/*
Theme Name: Adventure Tours Child 01
Theme URI:
Description: Child 01 theme for the Adventure Tours theme
Author: <a href="https://themeforest.net/user/themedelight">ThemeDelight</a>
Author URI:
Template: adventure-tours
Version: 1.1.1
*/

@import url('../adventure-tours/style.css');

.main-nav > li:last-child {
    margin-right: 25px !important ;
}

.price-decoration--without-price .price-decoration__label { display:none !important}

.slider {
    margin-bottom: -79px !important;
}

The style is not changing… I think i didn’t call it on function.php right…
What Is wrong here?
