When Shen Yanxiao made sacred tools for the leaders of the four countries, Tang Nazhi once asked her why even trash like Gu Lan and Gu Feng could have the sacred tools she created.
Her answer was simple — for the sake of mankind's overall strength.
Fighting against the devils, they needed all the strength they could get and that included the strength of the Iron Blood Mercenary Corps. Therefore, she let bygones be bygones and provided sacred tools even for Gu Lan and Gu Feng. In that way, they could have better chances to survive in the battle.
Why did she requite evil with good in regards to the Longxuan Empire?
That was also for strength.
All this seemed to be so selfless. In order to save the Brilliance Continent, she completely abandoned her grievances and joined hands with former enemies.
Quite the Holy Mother's performance.
