Why is Liang Geng weak?

Why are both Geng weak:

Look at the life span of the Japanese Lord, 1, the Japanese Lord is stronger than robbery, and there is no official killing without seal. Taking money as a god, the time when things happen may be the fate near the crown or the emperor's wealth and luck or the official killing of the tomb. 2. The Japanese Lord robbed without a seal. Why are the two people in the middle so weak? Rich people may be more dangerous than robbing the emperor or killing the Jedi. If there is no money in the middle, it is also dangerous to get hurt. 3. It is more dangerous to be impressed when you are growing stronger, than to rob the temporary officials Wang Di and Wang Yin, or to use the lucky stars to admire the Jedi and be at a loss. 4. It is the most dangerous thing in the longevity of the Japanese Lord that the Japanese Lord has no roots.
