Han Sen ended up not looking for Li Singhua in his lab, as he could have been rather busy. So, he sent him a message instead. That way, he could ask all the questions he wished to pose to the man.
He didn't really even expect a reply. But that very night, Li Singhua gave his response, answering each of Han Sen's questions with keen insight. He even provided Han Sen with links to further reading material on the subjects.
Han Sen saw his reply, and while he had received many answers, many of those answers merely led to him having even more questions.
Every now and again, Han Sen would continue to send Li Singhua a message with more questions. Each and every time, Li Singhua would reply within a day or two.
Now, Han Sen understood why Bai Yishan and Li Singhua did not get along. He could see now that it was due to their different methodologies of research.
