Seeing that some readers don't understand what the liver grade means, I specially wrote an article to popularize science for you.

The word "liver grade", if the author is not mistaken, should be derived from the liver ship (ship mother evil. Teach), because leveling up is a thing that takes a long, long time, and it's very boring, and it really hurts the liver and kidneys......

Gradually, it began to spread, and although it was not widely known, it was also accepted by some people.

So there is the following sentence structure:

Worship Mahatma Gandhi! (Kidney Male Liver Emperor)

I'm going to burst my liver! (I'm going to level up for dozens of hours straight!) ）

My liver hurts. (The leveling time is too long, and it's almost dirty, so I came out to post the level, and by the way, I expressed my feelings.) ）

Is your liver okay? (I use it when I see a dalao sun level.) ）

……

There are many more to enumerate, all in all, "liver level" is the meaning of leveling.
