Chen Cang decisively searched for "Persistent Vegetative State".
Soon, many items appeared!
"Detailed Explanation of Persistent Vegetative State in 2291": Exchange points 20,000.
"Overcoming Persistent Vegetative State in 2300": Exchange points 30,000.
...
There were many similar items, but they were very expensive!
These are things from across the ages.
Too expensive!
However...
Just as Chen Cang was about to give up, he suddenly saw an item he could exchange.
"Analysis of 100 Cases of Persistent Vegetative State in 2020", Exchange points: 200 points.
This was a paper, and a recent one at that, but it still cost 200 points.
Chen Cang gritted his teeth and decided to exchange for it and take a look.
Even if there's no gain, think of it as two pairs of smelly socks from Old Ma. 200 points is not too expensive after all!
After clicking exchange.
In no time, the content of the paper appeared in Chen Cang's mind.
