The girl that appeared out of the tianshu bamboo writing strip is Yun, a doll made using Mujia.
Yun calls the sword that appeared out of the tianshu the legendary Xuan Yuan Sword. Through Yun, Yin and Ning acquire new power.
Meanwhile, with a single word from Empress Cheng, Zhao is made chief engineer. He now works on developing constructs.
Mo Heng, who betrayed the empire and joined the rebel army, is also working on a new weapon he calls black fire armor.
I focused on developing constructs and 
knew nothing of the outside world.
ركّزتُ على تطوير المُركّبات ولم أعي بشيء
من العالم الخارجي
Ich konzentrierte mich auf
die Entwicklung von Konstrukten
Me centré en desarrollar constructos
y no sabía nada del mundo exterior.

Je me suis consacré au développement
des bêtes mécaniques,
Ero concentrato nel progettare i costrutti 
e non sapevo nulla del mondo esterno.
Eu me focava em desenvolver armamentos
sem saber nada sobre o mundo exterior.
Я был так сосредоточен на механизмах,
что ничего не знал о внешнем мире.
