The reward of this mission, the opportunity to promote to a Heavenly Soldier, is practically tailor-made for Su Xin.
Heavenly Soldiers aren't forged overnight. Even if Su Xin's Flying Blood Sword has a high chance of becoming a Heavenly Soldier, it still requires a long nurturing period.
To gain a Heavenly Soldier is simple; apart from the material, the most crucial thing is time.
Just like in Cen Weizhuang's case, it took several decades to nurture the four Taoist Swords into Heavenly Soldiers. Unfortunately, in the end, they were all destroyed by Su Xin's Fatal Fifteen Swords.
"System, promote my Flying Blood Sword to a Heavenly Soldier." Su Xin commanded.
As soon as his word fell, a flash of light illuminated the Flying Blood Sword in his hand, and a change materialised instantly.
