After the virus from the most recent experiment injected into Sisi's body had all died, Yang Ping conducted a new experiment on her, once again injecting the K virus into her body. If a ratio of three percent in eradicating tumor cells can be maintained each time, then there is great hope for Sisi to control her illness and even be cured.
Following the second and third trials, Sisi's heart function miraculously showed some recovery. Yang Ping decided to try weaning her off the ECMO gradually, and after attempting to do so step by step, Sisi eventually succeeded in getting off the ECMO.
After the ECMO was removed, Sisi was able to get an MR scan. Xia Shu sent Sisi to the imaging department for an MR. After the MR images were obtained, Yang Ping measured each tumor on the MR images.
