"There is no need for that, thank you. He is in good condition, and he will heal even quicker within the next few days." Jiang Yao prepared Director Lee for what was to come. Starting now, she would concoct every one of Lu Xingzhi's medicine from the Medical System lab and do a switch with the hospital's medicine to avoid any suspicion and cover the existence of her own medicine.
The medicine that she was able to synthesize and concoct in the lab was way more advanced than any medicine found in the hospital. This would be helpful for Lu Xingzhi to heal faster.
Telling Director Lee that Lu Xingzhi's healing progress would speed up was to ensure that the director would not be startled seeing how good his condition would become in the next few days.
Just like so many other things, the impact of knowing something beforehand and finding out suddenly were vastly different.
