Yun Jiao had long known that the formula for White Medicine was something Wanyan Zhang was determined to obtain.
Along the way, she also devised a strategy to counter it. She quickly picked up the pen and wrote down the detailed production methods of both the White Medicine and the Bruise Oil formulas, and handed them to Wanyan Zhang.
As soon as Wanyan Zhang got the formulas, he left and returned to the main courtyard, then instructed the guards, "Go and call Doctor Chen over."
The Prince Mansion always kept a doctor on staff, who was a retired Imperial Physician and loyal to Wanyan Zhang.
Doctor Chen soon arrived. Wanyan Zhang pointed to the two prescriptions on the table, "Take a careful look at these two formulas and see if there are any problems."
