As for your question, as long as it is limited by the anti-addiction system, you need to have a five-hour rest time, and it is impossible to accumulate only 2-3 hours.
As for what you mentioned, how long does it take to log off after 3 hours online a day? This situation also requires you to rest for 5 hours to play normally.
However, please pay attention. Let me give you an example. For example, if you start the game for 2 hours in the morning, then you go offline for 3 hours, and you continue to play after 3 hours, then you will be restricted by the anti-addiction system after 1 hour, but you only need to go offline for 2 hours to play normally. Because you have a 3-hour break in front of you, the time of the anti-addiction system is cumulative, regardless of your game time or rest time.
