If there was one word to describe Wei Chenghe's state of mind at the moment, it would be conflicted.
He was an atheist, but here, the God he denied was the so-called omnipotent deity, not the ghosts and spirits people feared, because he always believed that there were still many things in the world that science could not explain. The reason science was called science was because everything within its theoretical scope could be explained and verified by scientific methods.
Therefore, science cannot explain things outside of its theoretical scope. Fortunately, with the progression of science and technology, more and more phenomena are being encompassed by it.
Upon leaving the tech department, Wei Chenghe sighed, "Perhaps, as times evolve, humans, gradually becoming masters of all things, have lost their awe of nature and the unknown, leaving only a few scientists still embarking on the unknown path with a humble heart."
