The Mysterious Businessman of the Apocalypse

In the apocalyptic world, zombies are rampant. Everyone is struggling to survive in the apocalypse, but what about Ding Yuan? "Brother, what can I say to you? This second-hand Gatling, with its speed, firepower, and ferocious pull, is a perfect weapon to deal with the tide of zombies!" "Money? Talking about money hurts feelings, I'll give it to you for free!!" "Brother, our friendship has been preserved. Please see if you give me half of the property rights of this base. I am not cheating you!" "Look, don't be mean. If I attract two waves of corpses, I'm afraid you won't be able to survive." "Okay, from now on we are brothers. Each person owns half of the base. If you buy weapons, I will give you a 10% discount!"
