Over the long course of thousands of years of human history, people had continued making breakthroughs in the field of medicine.
Many terminal illnesses that had once seemed incurable had gradually found solutions with the continuous advancement of technology.
Many terrifying diseases whose causes could not be identified had also gradually been exposed by medical instruments.
At the same time, however, as humanity's understanding of these illnesses grew clearer,
people truly began to realize just how fragile they were when faced with matters of probability, even as the apex of Earth's biological chain.
Cancer—or, more precisely, malignant tumors.
The main cause of this disease was genetic mutation, somewhat like the several lizard genes forcibly introduced into Zhou Xun's body.
Once an error occurred during the replication and transcription of DNA as cells divided, tumor cells could appear.
These cells did not directly devour the body's normal cells. They only fought for nutrients while rapidly multiplying and reproducing themselves.
They spread to other parts of the body at a terrifying speed, compressing the functions of normal organs and ultimately causing organ failure.
In terms of their nature, they were indeed frightening, but they were not as overbearing as the Blood Plague Virus.
The former did not attack the cells humans already possessed, whereas the latter directly devoured cells and converted them into nutrients for itself. It could even destroy the immune system.

After bringing Zhou Xun back to the second floor and sitting down, Su Mo got straight to the point and questioned him while holding the examination records.
