After a few days of pondering, Lin Lin was still confused about the connection between her and Lin Yi. In her words, it seemed that there was an invisible cord between their brains. When a voice called her, if she responded, she could sense the connection with Lin Yi.
The connection was mysterious. Not only were thoughts shared, but even things that were difficult to describe, such as thinking, knowledge, and experience could be shared through this connection.
In a nutshell, it was like two servers connected in parallel. Because the digitalized human possessed computation power comparable to the quantum computer, Lin Lin would be the host. Lin Yi held the knowledge of "Mechanism of deep brain wave action and nonspecific projection system of cortical thalamus". Although this knowledge was outside of Lin Lin's field of research, Lin Lin could "burrow" this knowledge stored in Lin Yi, like burrowing a hard drive, via this connection.
