Fifteen-year-old Jing Cheng can hear the whispers of the souls of all things - the sadness of raindrops, the loneliness of old trees, and the sighs of vegetation. This ability called "Heart Abyss" caused him to suffer from emotional torrent and was regarded as a "disaster". During a heavy rainstorm, he rescued a ball of snow-white fur: Xiaotuan. This cute beast with glazed eyes and butterfly wings cuddled up to him, making his restless heart feel at peace for the first time.
A soft and gluttonous little ball, it looks like it needs protection, but in fact it is the only remaining spiritual core of the ancient "Guardian of the Heart Abyss". The main body is sleeping deep in the world. It can only be parasitic on Jingcheng and maintain its immortality through its vitality. They are interdependent: Jingcheng is Xiaotuan's "source of life", and Xiaotuan is his "spiritual anchor".
In the warm porridge and rice of the aunt, in the innocent smile of the cowherd boy A Zhu, in the warning of the pharmacist Yungui and the silent resonance of the librarian Suxin, Jing Cheng takes the small group on a journey of "returning to the heart" - listening to the obsession of the living spirit, and finding relief and peace for the lost soul. Every healing is a two-way redemption.
When the small ball quietly glowed to calm the storm, and when Jing Cheng saw in his dream that the giant shadow of the star abyss was connected to his own destiny, he gradually understood that the most powerful protection is often hidden under the softest appearance. True growth is to learn to listen to the heartbeat of the world, and to guard your own heart and soul amidst the hustle and bustle.
"Hear the Heartbeat of the World" - a warm fairy tale about empathy, companionship and the power of silence. There is no villain, only an ununderstood soul; there is no love, but pure bond; there is no battle, every step is to fight against the inner storm. When you finally hear the heartbeat of the world, you will also find inner peace.
