Human Brain

Liu Di turned the diary page and looked at the next one.

'My consciousness actually left my body and entered a world of absolute nothingness.'

'There, I could use my imagination—what they called mental power—to manifest any object, as if dreams had come true.'

'I also saw Xiao Jie there. He said he could travel through it.'

'Following that clue, I discovered the true nature of consciousness.'

'Consciousness is the chemical reactions between the dendrites, axons, and myelin sheaths of neurons in the human brain. They transmit through chemicals such as dopamine and acetylcholine, forming electrical conduction between two synapses.'

'So, if consciousness could take tangible form, it should be something similar to an electric current.'

'It is simply like photons: when stationary, it has no form and no mass.'

'I am merely seeing flowers through the mist.'

'Perhaps only philosophers can explain all this.'

'Besides, there is one more thing that terrifies me.'
