Su Xin's fame had spread throughout the entire Jianghu, but to the Golden Khanate, Su Xin's reputation, or rather, his notoriety, was even greater than in the Central Plains Martial Arts.
Both of their Great Khans had died at the hands of Su Xin.
The first Great Khan 'Sirius' Moge was slain by Su Xin in coalition with the Seven Heavenly Suns right in the Central Plains; it could be said that Su Xin truly rose to fame by stepping over the life of Moge.
Later, after Su Xin advanced to True Martial, he even killed their second Great Khan 'Ancient God of Moving Mountains' Ordo within their Golden Khanate territory.
The Golden Khanate, although considered a dynasty, valued powerhouses above all else; the harder you hit them, the more they revere you.
That was the case with Su Xin; with two successive Great Khans dead by his hand, their reverence for Su Xin was beyond measure, even to the point of fear.
