A large aftershock caused the walls to creak.Zheng Ren and Su Yun's faces turned pale. Although this space was supported by a lead wall, it definitely could not withstand another aftershock above level 6.They had just sent a patient out but the new patient had not been brought in yet. In the narrow and cramped space, there were only Zheng Ren and Su Yun. This could be considered a blessing in disguise.At the very least, they did not need to worry about the patient's safety. They just needed to protect themselves.Because of that, the chances of survival were high...but not by much.Zheng Ren and Su Yun's actions were almost identical. At the same time, they hid in the corner that looked the sturdiest.After that, they looked at each other but no one said anything.Fear and uneasiness dominated the place. Although Zheng Ren and Su Yun risked great danger during surgeries, it did not mean that they were not afraid.
