Warlord

At the same time, he took out a custom-made grenade the size of an egg from the portable device on his back.

This hand grenade was called sonar. It would not explode, and it did not have any destructive power. However, after the sonar is activated, an ultrasound is sent out to scan the current environment. Through the Doomhammer soldier’s standard battle tactics table, he could receive the feedback from the sonar to establish an environment model to provide a clear terrain display.

Generally speaking, sonar mines are mainly used in complex environments. For example, the tunnel in front of him.

After pressing the start button of the sonar, Zero tossed the little thing out. The special elliptical grenade hit the ground. After the red light in the center flashed three times, the sonar grenade cracked on all four sides, forming a miniature launcher. The next moment, a formless sound wave was emitted from the little guy’s body. It spread in the air at a speed of 340 meters per second, quickly sweeping across every inch of the tunnel.

Zero at the same time opened the tactical table on his wrist and received the sonar feedback. There were green lines on the background of the black screen that rapidly constructed the tunnel model. All of a sudden, the complicated terrain of the mine tunnel was memorized by Su Bai.

Behind him, the sound of many footsteps could be heard. Without any further hesitation, he flew towards the depths of the tunnel.

Although this abandoned mine had been turned into a base by the thieves, with their economic and technological strength, they were unable to transform the mine any further. In addition to repairing the electrical system that was used for lighting purposes, the bandits had also built simple sheds around the mine, as well as repairing some of the mines in the surrounding area to serve as temporary parking places for supplies.

Thus, the coverage of electricity was limited to those places. As for the zero-depth mine tunnel, it was already out of the bandit’s range of modification. They followed the trail into the tunnel, and once they passed the area covered by electricity, they came face to face with a black mass, as if there was no end to the tunnel.

Normally, even wolf thieves rarely entered these mines. Sander knew that these tunnels were very complicated, and because of the years of disrepair, the fixed frames of some of the tunnels had loosened, and several of the tunnels had collapsed and been sealed off. Thus, there were too many dangerous factors in the mine.
