This discovery broke through Su Ren's existing knowledge.

It's not unheard of for zombies to cooperate.

In game works that are generally recommended for players to play for more than 100 hours, the difficulty of monsters will increase.

In the middle and late stages of the game, not only the types of monsters increase, but even the original basic monsters will be improved to a certain extent. The cooperation of monsters has always been a difficult point in improving the difficulty of the game.

Players all have a common understanding: the more difficult the game, the better the monsters are at cooperating.

Of course, accidentally stepping into the hatred range of a group of zombies and being swarmed up to eat them does not count as cooperation.

Like this, only when there is "assignment of responsibilities" and "communication" is there cooperation.

Although the coordination ideas shown by these zombies are still very simple, there is still coordination.

Su Ren was very reluctant to draw this conclusion.

"Be extra careful."

Su Ren could only tell himself this.

"The world may be more dangerous than previously thought."

This was only the first day of the outbreak of the biochemical crisis and the virus infection. And on the first day, the zombies had such keen hearing and the ability to simply cooperate.

"By introducing difficulty-increasing settings so early, does this game want people to die?"

Su Ren, who had read a lot, looked very ugly.
