Based on the provided story, I will rate its Tragedy Degree and Comedy Degree according to the specified criteria.

### Tragedy Degree:
- The story contains some elements of mystery and potential danger, especially considering the risky and dangerous nature of the alchemical text that could alter human DNA.
- There is an underlying tension regarding the ethical implications of the discovered knowledge.
- However, there are no significant emotional setbacks or profound tragic occurrences within the narrative itself.

### Comedy Degree:
- The story does not include any evident comedic elements or humor.
- It has a relatively neutral, albeit slightly positive, ending with the formation of an alliance focused on responsible use of the discovered knowledge.
- There is no extreme happiness or emotionally delightful conclusion.

Given these considerations, the evaluation would be as follows:

```json
{
  "TragedyDegree": 3,
  "ComedyDegree": 2
}
```

The Tragedy Degree is rated at 3 points due to the presence of potential risks and ethical tensions, but without significant emotional impact. The Comedy Degree is rated at 2 points because the story lacks comedic aspects, although it ends on a mildly positive note.
