Li Ming Hao had told Su Xin Yu the secret behind the abnormalities of the animals in this ecosystem. If it was really due to the presence of natural nuclear material here, they were all in great danger. No matter how secure the buildings were, the people were still being exposed when outside. And given how lovely the place was, there was no way people were not spending their time in nearby mountains at least, regardless of the dungeons.
After hearing it, Su Xin Yu was more adamant to take both of them out. They were in the unprotected part of the cave, even one day exposure could harm them.
"I will be at the back room," Li Ming Hao said to the attendant who was showing him around.
