Chapitre 687: Mutation in the original world (1)

With the strength of the elves, it was not difficult to get these things!

Tang Zhen saw metal monsters placed on the city wall in front of him. Several pitch-black metal tubes were revealed from their mouths as they aimed at the bottom of the city wall.

Behind it was a boiler-like device, from which faint steam rose.

At the same time, on the back of the metal monster, there was a round metal bucket filled with a large number of metal bullets!

Obviously, this was a kind of foreign world's city defense weapon that used steam to launch bullets. Its power was still unknown, but just by looking at its size and those bullets that were the size of quail eggs, one could tell that its lethality was definitely not ordinary!

There were more than 300 similar weapons and equipment on the city wall of the elven Imperial City!
