Bei Shan originally didn't have to act this reserved and suppressed, but he really didn't want to be dragged into the Ryong Family's business. At least during his normal life outside of being a Dragon Blade, he didn't want to offend the Ryong Family, since only bad things could come out of it.
However, these four bodyguards clearly didn't want to leave empty-handed, and that made him a bit speechless.
After they began fighting, Xu Cheng went back and found some clothes to wear. He just wanted to avoid the search earlier, and then after putting on some clothes, he went back to the pitch-black corner in the living room and watched Bei Shan fight those four guards.
