Lin Wu was momentarily startled, but under Gu Siyin's anxious gaze, her expression quickly returned to normal, understanding what Gu Siyin was trying to convey.
"You mean," she said, "it's because Teacher Chi is a native of the Underground City, and the meteorite here was once part of the Underground City. So, as descendants of Teacher Chi, we also share half of the Underground City's bloodline, and that's why we are not affected by the radioactive toxins within the meteorite, allowing us to wear it for extended periods?"
"Exactly!"
Gu Siyin nodded vigorously.
She continued, "However, after three years of day and night research by Laboratory 49, a special reagent has been created that can extend the time ordinary people can wear it. Some people with strong physical constitution and special blood types, after specialized training, can also adapt to the meteorite pieces and wear them for longer periods."
