It could be because Green Star wasn't very precise in its expression, so Wandering didn't fully understand.
Lu Chen felt that using the "Law of Entropy Increase" would be more convenient to explain this phenomena, so he immediately started to explain it to Wandering.
Simply put, "entropy" is actually a special term in thermodynamics, which measures the degree of disorder in a system or system.
That is to say, entropy can be understood as a measurement unit just like length in meters or temperature in degrees; the former describes clearly visible numerical values, while entropy describes the degree of disorder in a system.
When the degree of disorder in a system decreases, it is called entropy reduction.
When the degree of disorder in a system increases, it is called entropy increase.
The Law of Entropy Increase proposed because of entropy increase is the second law of thermodynamics.
