He has a certain ability to improve the hardness of his body. He was stabbed several times with only minor injuries. Mian remembered that Aurora once said: "People who are good at swimming are easy to drown Putting the words "death" on Haman can make people who are good at blocking swords and guns with their bodies easy to die under swords and guns," and Lumian has the "Fallen Mercury" blade of the cursed wind.
In addition, "Hammer" Aite, who lives in the settlement of the members of the Stinger Gang, will come out alone from time to time to find the "bald" Harman who is a street girl and dancer singer, which is obviously easier to assassinate than a large group of people. Speaking of "Hammer" Aite, he is closer to the core of the power of the Stinger Gang, and he will know more secrets. But the problem is that if you really set up a trap and use Corrupted Mercury to "deal with" the "bald head"...Haman, then it is impossible to capture the other party alive and force him to ask for information.
If Lumian could beat Harman the "bald head" after stabbing him, and catch him somewhere in Trier underground, why would he want to stab him first?
