Yang Jing's pupils trembled as he held the key from Si Taizhen.
He had been in Si Taizhen's manor for some time and knew there was only one vault. All of Si Taizhen's rarely used treasures were stored within it, not just Spirit Medicines.
Furthermore, the Jade Poison Kingdom was rich in Spirit Medicines. Since Si Taizhen was deeply trusted by the Sovereign and frequently rewarded, the vault held countless precious Spirit Medicines.
The key felt scorching hot in his hand.
Out of the corner of his eye, Yang Jing could see Eunuch Gui's eyes were as wide as saucers, utterly horrified. He clearly hadn't expected Si Taizhen to make such a move.
Xu Qian's eyes seemed to drift about, as if she had no idea what the key signified. In reality, her heart was already ablaze with greed.
