Three Students and Chen Hai

"System, why can I speak english? Was that your doing?" Chen Hai asked the system. But the system did not answer. Chen Hai vaguely felt that he could speak more than just english. He seemed to be able to communicate fluently in any language used to communicate with people. But if asked to write it out or talk to himself, Chen Hai felt like he could not speak it. Language existed in a quantum state within Chen Hai. If someone spoke to him, then he could speak it.
