I Am The Invincible One

In a sweltering southern war zone, Faang Yu, a seasoned warrior trained from a young age, is ready to re-enter the everyday world after eight years of rigorous combat training. His grandfather, a revered figure, equips him with a bank card containing thirty billion yuan and a powerful Heavenly Dragon Token that commands respect and authority. This token also ensures the allegiance of local warzone soldiers and protection against any threats. As Faang Yu prepares to leave, he's reminded of his obligations to consider marriage proposals from prestigious families and to address a contentious issue with the Su family, who dare to annul a marriage agreement.
Faang Yu's journey takes a significant turn upon his arrival in Diannan City, where he encounters Su Ningshang, his supposed betrothed from the influential Su family. Despite their initial mutual disdain, a sudden attack by armed men intent on kidnapping Su Ningshang thrusts them into an unforeseen crisis. Faang Yu, underestimated and overlooked, reveals his true capabilities when he confronts the kidnappers with a chilling calmness and authority.
Will Faang Yu's unyielding stance against the attackers uncover a deeper plot? And how will this confrontation impact his relationship with Su Ningshang and the Su family's standing?
