Pressure

Little North suffered a mental breakdown. 

The moment the first zombie was beautifully beheaded by Happy, he already felt like breaking down. But he still did his best to provide an explanation in his heart to convince himself that this was just a coincidence. How could a zombie with a body as tough as steel have its neck so easily cut off?

But this happened three times in succession. Three zombie heads landed on the ground, and Little North suddenly felt that his precious zombies, which he had persisted in leveling up for around two months, had begun to shudder. 

Little North could say nothing about that, but Happy looked as if he had just done something very insignificant. He instinctively went to search for the spoils of war left on the zombies' bodies in a very calm manner, even if he found it to be a little disgusting. 

After some time, Happy got up while feeling a little gloomy.
