History's Strongest Master

"I asked you to kill Zhu Changling so that you would understand that in this world, people are evil, and humans are harmed by the tiger. When you treat an enemy, you must be ruthless."
In a mystical world far removed from Earth, Lin Yuanjian, a young man from Earth, finds himself in the Heavenly World after a miraculous recovery from multiple cancers, thanks to a powerful system. This system not only cures him but also transports him to this new realm with a mission: to collect one hundred and eight disciples and cultivate the "Great Dao Origin Heavenly Scripture," the key to returning to Earth.
Lin Yuanjian's first disciple is Zhang Wuji, a talented but naive youth who had been poisoned and betrayed by those closest to him. Utilizing the system's unique ability to modify and enhance martial arts techniques, Lin Yuanjian cures Zhang Wuji of his poison and imparts to him a perfect version of the Nine Yang True Scripture, elevating his cultivation and setting him on a path of strength and revenge.
The story unfolds with Lin Yuanjian guiding Zhang Wuji through the complexities of the martial world, emphasizing the importance of being ruthless with enemies and cautious in trusting others, especially women who had previously deceived Zhang Wuji. Lin Yuanjian's wisdom, along with his uncanny knowledge of Zhang Wuji's past, cements his status as a near-godlike figure in Zhang's eyes.
Lin Yuanjian's journey is not just about teaching martial arts; it's a quest to gather disciples who fit the criteria of the 36 Heavenly Stars or 72 Disha Stars, crucial for fulfilling his system's requirements. His encounter with Zhang Wuji is just the beginning of this extraordinary adventure that blends martial prowess, strategic mentorship, and the relentless pursuit to return home.
