Chapter 249: Six-barrel fire god cannon construction blueprint (2)

Looking at the blueprint that had just been opened, Zhang Shan was a little confused.

What the hell was this? what the hell was a city-guarding equipment? The players didn't have a city, so how could they defend it?

It can't be used during a monster attack, right?

No matter how he looked at it, it didn't look like it. The monster attacks were happening outside the city.

Where are you going to put this six-barrel Vulcan cannon? the NPC Army is standing on the city wall.

The players went up again.

Could it be that in the future, players would be allowed to build cities? That was interesting.

Of course, Zhang Shan was just guessing. Anyway, it was still too early for this. His current life profession had only just advanced to an engineer.

the six-barrel vulcan cannon, on the other hand, was a level 4 blueprint, and one could only start learning how to make it after becoming a master engineer.
