Yan Feifan was in the neurosurgery lab. He made some brief preparations and waited for about ten minutes before a young doctor in scrubs rushed in with the experiment samples.
These were four tumors, the smallest the size of a peanut, the largest like a quail's egg.
They were pale in color and soft to the touch, much like the yolks inside a hen, and their shapes were somewhat irregular.
Not long ago, these tumors had been inside a patient's spinal canal.
After being successfully removed by the neurosurgeons, they were sent to Yan Feifan at the earliest opportunity.
The experiment Yan Feifan needed to conduct was to inject 95% concentration ethanol into these tumors and observe the changes.
However, the data from this experiment could only serve as a limited reference.
This was because the pressure, temperature, humidity, and other conditions the tumors were subjected to inside the spinal canal were quite different from the conditions in the lab.
