Chapter 673: The Underground Stronghold

To keep it safe, Vivian threw a little bat down there again. This time, she allowed the little bat to fly down with a small piece of protective crystal. Looking at the little one flying unsteadily into the passage, Hao Ren worried that it would hit the wall, but luckily, it reached the bottom smoothly.

There was an interconnected tunnel world under the metal pipe, which structure was as complex as an ant's nest. Vivian found the chimeras' route based on the traces of blood on the pipe and she also discovered a lot of the monsters that died in the pipe. They died together with their upper bodies all burnt and the cause of the burning was a short circuit fault in their black electric vests. It seemed that the electromagnetic pulse bomb thrown by Hao Ren worked. Not only did it blow up the mechanical control parts of the metal pipe, it also killed a large number of monsters that were rushing out, and blocked some of their exits.
