The Lizardmen's biggest problem so far was that they were a tropical race that had lived in tropical regions year-round.
It was like how some tropical plants could not survive at all after being transplanted to another region and could only be cultivated in a Medicine Garden established in a tropical Rainforest. The Lizardmen were in much the same situation.
As a tropical race, once they left the environment in which they had originally grown, they could suffer from acclimatization problems caused by climate changes.

Zhou Xu acted as soon as he thought of it and immediately unlocked the Survival of the Fittest project.
The first level only provided a slight improvement, which was nowhere near enough. After unlocking it, Zhou Xu immediately began upgrading the project on the spot.
The second level provided a minor improvement, while the third level provided a significant one. Needless to say, Zhou Xu's goal was to raise it to level three first.

"Enormous risks."
Risk warnings were generally divided into four levels: slightly high, too high, enormous, and extreme.

Only then did Zhou Xu notice that after
