If you include the year she was reborn, it was three years ago that she saved Olden's son.
At that time, Olden's son was traveling in Europe when he was kidnapped by terrorists. Despite various threats and temptations from Tullos, the terrorists refused to release Olden's son. The terrorist organization had a church that worshipped death and evil. They planned to use Olden's son as a sacrifice to honor their holy war, and a king's son was the perfect offering.
Given Tullos' national power, the chances of rescuing Olden's son from an armed terrorist group were slim. Olden, in despair, sought help from China. Because it was a significant issue, the elder sent Musheng personally to rescue his son.
In that mission, she single-handedly destroyed at least three terrorist bases to free the hostage. That battle made other countries realize the existence of such a formidable Chinese special forces operative, and surveillance on her has never ceased since then.
