Yang Jian of course knew that Professor Bai was spouting nonsense. Once these literary masters start to bluff, they can disorient you to the point where you can't find north, and every sentence they utter is grounded and evidenced, leaving you unable to find a reason to rebut, because quite simply, he has read more books than you, and you cannot win a debate against him.
Except for some hot-tempered old guys who like to jump up and fart about it.
But Yang Jian understood more clearly that the real purpose of this rhetoric was actually to cover up a part of the truth, to make people able to accept the present appearance of malevolent spirits, and at the same time, not to completely despair.
This was beneficial for ordinary people.
It was also beneficial for the stability of the global order.
Therefore, Yang Jian was very interested in what kind of story Professor Bai, brought in by headquarters to lecture, had prepared to convince everyone.
