Xiao Yan is a passionate young man who possesses an indomitable spirit. From a young age, he aspired to reach the pinnacle of the Martial Continent. However, fate had a challenging path in store for him. Hindered by societal prejudices, people doubted that Xiao Yan, whose origins were shrouded in mystery, could attain true power. He was often viewed as an outsider. Despite the skepticism and oppression he faced, Xiao Yan did not falter.

His unwavering gaze seemed to embody a disdain for the world's compromises, weaknesses, and irrationalities. This perfectly captures the essence of the theme "Never Underestimate a Youngster" from the novel "Battle Through the Heavens." His fervor and perseverance would eventually transform into a dazzling spectacle. If Xiao Yan is the most brilliant star in "Battle Through the Heavens," then Xiao Xun Er is the gentle moonlight that softly rests upon his shoulders.

Xiao Xun Er is Xiao Yan's childhood friend and has been by his side as they grew up together. While the world doubted and questioned the origins of the enigmatic young man, Xun Er had already been deeply moved by Xiao Yan's tenacity and persistence. Perhaps it was the affection that blossomed during their youthful years that led to their inseparable companionship in the future.

Throughout Xiao Yan's arduous journey, Xun Er silently supported him from behind the scenes. She understood that this stubborn young man was destined to embark on a perilous path. Although it inevitably tugged at her heart, she believed that one day Xiao Yan would return triumphantly. Aside from Xun Er, "Battle Through the Heavens" also features a captivating and alluring character named She Cai Lin.

She Cai Lin draws inspiration from the famous Greek mythological creature, Medusa. However, in this adaptation, her name is modified to sound similar to "snake" in Chinese, and her beauty is comparable to the colorful scales on Medusa's head. When she first appears, She Cai Lin showcases formidable strength and a breathtakingly beautiful appearance that captivates countless young men and women.

She effortlessly resolves the crisis that Xiao Yan faces. This snake-human queen exudes grace and composure, as if toying with her prey while effortlessly maneuvering through the encirclement. She Cai Lin's elegance is unforgettable: her serpentine tail gracefully sways along with her movements, and her long, ink-black hair dances in the wind.

Beneath her serene and gentle exterior lies a poignant and touching story. She carries a dangerous "Calamity Poison" within her body. Anyone who approaches her will be afflicted by this deadly toxin. As a result, Xiao Yi Xian has spent years secluded, practicing medicine in solitude, avoiding contact with others.

However, one day, while rescuing a small creature, she accidentally falls off a cliff and injures her delicate foot. Xiao Yan does not hesitate to jump off the cliff and carry the distressed young girl on his back, defying the dangers posed by her poisonous condition. Thus, they embark on a life-or-death escape journey amidst treacherous mountain cliffs.

Xiao Yi Xian, She Cai Lin, and others make a resolute decision to stand by the young hero's side, advancing and retreating together with him. With their collective efforts, the valiant young hero ultimately leads them to a glorious victory, repelling the vast army of the Yunlan Sect. People rejoice and hail Xiao Yan as a great hero.

After enduring numerous trials, Xiao Yan, once an unknown youth, finally steps into the legendary realm known as the Holy Land. It is a realm that even the strongest individuals have been unable to surpass for countless years. The path has not been easy. Memories of the arduous obstacles along his journey flood Xiao Yan's mind.

He realizes that without the companionship and support of his friends, he would not have reached this point today. The bold promises made during his passionate youth have not been in vain. With a gentle smile, Xiao Yan continues to stride forward, seeking his next goal in this vast Holy Land.
