OH this makes sense! I remember there was a scene where people were melting once they hit the sun! Geez, of all the things a scientist can invent -__- You are a lifesaver xia0yuer! If it wasn't for you answering my questions, I probably would've given up this dramaSo, Lei Ting Ji Hua is literally Sound of Thunder Mission. It's a biological weapon that Professor Hermann created in England. It basically makes you extremely light sensitive, so much that you start burning up if the light hits your skin. It's a bloodborne pathogen, so that's why A'Ci was able to get infected just by touching they dying man's blood. (I don't think you're quite there yet.)
I have more questions for you!
Is there something going on between Rong Hua and A'Ci? Like romantically?
And what was that blue liquid that A'Chu and his doctor friend? Could it be the antidote to the lei ting ji hua virus?
Going back to the ji hua, does this mean that the Japanese knows how to make it? Because A'Ci's mom was testing people... But if they have the plan, why would they need it from A'Chu?
