Zhongli was a rich CEO (OMG ZHONGLI AINT BROKE?!). He made robots, Childe or Ajax was his recent creation but he only made one model which he did not sell, in fact he kept Childe for himself. Childe always somehow managed to break himself as he always liked to sneak out constantly.

One day Childe had been found by one of Zhonglis bodyguards, he returned Childe to Zhongli but unfortunately Childe had broke again. — Ajax…Explain to me how you ripped off your arm? Zhongli sounded pissed.
