Edit: People seem to think I was kill farming him. This is not true.
This is everything what happened:
-He kept respawning and attacking me
-He had obsidian around his egg and I only had an iron pick, so I couldnt destroy his egg.
-I did however have a lot of obsidian I was going to use to protect my egg (before he destroyed it)
-So I did what I could-I placed obsidian between him and his shop and the other islands so he couldnt get good stuff and kill me when I returned with my diamond pickaxe
Then, when I came back, I took the screenshots. Keep in mind that when I took the screenshots was not when I placed the obsidian. When I placed the obsidian it was because I had no other option. I had only leather armour, a wooden sword, and a lot of food and obsidian.
The high amount of kills was from other people. I had like 23 kills from other players (and 0 deaths), I only killed him a few times when he tried to attack me.
