Chapter 866: The Cave

"Mechanical soldiers enter the cave." Transformers gave the order. If the rats enter the cave, they must be eradicated, otherwise they will be troublesome sooner or later. Anyway, they can't get in with their big bodies.

The mechanical soldiers standing at the entrance of the cave put away their guns, took out pistols and bayonets, turned off the light source, and the red mechanical eyes were dim. Then they took smoke bombs, tear gas bombs and grenades and entered the cave. The mechanical dogs had to continue tracking. Only the mechanical soldiers had diversified weapons and were suitable for fighting in the cave. To be honest, the mechanical soldiers didn't like to get into the cave. These jobs used to be the work of spider robots.

The ping-pong-sized reconnaissance device was exploring the way ahead, and the fan-shaped scanning beam was mapping the cave in detail. All the reconnaissance devices began to map the caves on the map. According to the direction of the caves, they could roughly judge where some caves led to and some caves might be connected.

After entering the cave, the mechanical soldier's vision screen changed to green, still mainly infrared. The dark cave was particularly humid and had a strong smell of earth, and there was also some rotten smell mixed in it. It can be seen that these caves have not been used for a long time and have not been perfected. If humans stay in the cave for a long time, there will definitely be problems, at least the mental aspect will become depressed.

You can only bend over to move forward in the cave. The mechanical eye can clearly see the place where residual heat is still emitting when scanning the cave wall. According to the heat residue, the mechanical soldier quickly searches forward and closely follows the reconnaissance device within a distance of no more than one meter.

"I think we should make some mechanical mice, or groundhogs."

The mechanical soldier walking in front complained as he walked. Each group consists of five mechanical soldiers, so that they can split up and pursue when they encounter a fork in the road.

"In fact, it is better to make mechanical ants. Ants with finger-lengths will swarm into the tunnel like swarms and will definitely eat up those damn cave people. It's really boring to stay here." A mechanical soldier bent over and was very unhappy.

As he walked, water appeared under his feet. The temperature of the cave wall in front of him was warm. The mechanical soldier was sure that there was definitely an enemy ambush. After thinking for a while, he stretched out his mechanical hand and pressed it into the water, and began to accumulate voltage. The voltage index rose until it turned red. There was so much water here and those enemies were hiding in the water. It would be a shame not to shock them.

Clang! The electric current instantly spread along the turbid water...

In the quiet cave, only muffled groans and heavy objects falling into the water were heard from the turns and forks in the road ahead. The mechanical soldier nodded, stood up and walked forward with his pistol and bayonet. After turning the corner, several enemy soldiers were lying in the water, twitching all over and foaming at the mouth. No wonder the electric shock effect was so good, these unlucky guys were barefoot.

At the fork in the road, the five mechanical soldiers split into two groups and continued to move forward.

The reconnaissance device was in front and the mechanical soldiers were behind, constantly moving deeper into the cave. On the ground, mechanical dogs and other mechanical life were searching back and forth, and there were pursuers underground. Those enemy soldiers were really desperate.

Bang! The mechanical soldier who had used electric shock finally opened fire. The pistol bullet penetrated the throat of an enemy soldier, and then continued to fire and hit other soldiers behind him. Gunshots continued to ring out in the dark cave. Every shot would illuminate the cave for a moment. The dull gunshots made the soldiers hiding behind feel numb in their ears. It was really uncomfortable to shoot in a closed environment.

"How many enemy soldiers are there in front?" A mechanical soldier behind asked.

"About twenty or so, the firepower is quite strong."

While talking, a series of bullets swept over the two mechanical soldiers, sparks flashing and clanging all over their bodies. The opponent did not have a pistol suitable for fighting in the cave, so he had to use AK to sweep randomly.

"I said, why don't you throw a grenade!"

After the mechanical soldier behind reminded him, the mechanical soldier in front remembered that he still had a grenade with him. Without saying a word, he took out the autonomous tracking grenade and threw it out. The half-flying grenade suddenly flew towards an enemy. Then, the two mechanical soldiers stuck their mechanical hands into the sides of the cave wall to fix themselves. There was no way. All the energy generated by the grenade explosion would spread along the cave. Who knows if they would be knocked down by the impact.

"Ah...!"

The two mechanical soldiers were too lazy to translate the chattering voices in front, but the last scream, which was an international common language, could be understood without translation. It was nothing more than a word to express the degree of surprise.

Boom! !

On the ground, a mechanical dog that was searching for traces of the enemy suddenly felt the ground vibrate upwards. The dog head looked around and finally looked at the ground...

The two mechanical soldiers did not feel any consequences of the grenade exploding in the cave. The enemy soldiers fainted directly, and blood was flowing out of their mouths, nostrils and ears. Those who were close to them even had blood in their eyes. They were directly shocked to death. There was no shrapnel on their bodies. They were completely killed by the shock caused by the explosion in the closed environment.

"How miserable." The mechanical soldier who threw the grenade said as he looked at the corpse.

"Yes, yes, these few were directly killed. Let's use grenades to clear the way next."

"Good idea."

The two guys then started throwing grenades non-stop. The mechanical dog on the ground only felt the ground shaking constantly. Influenced by the two mechanical soldiers, other mechanical soldiers also started throwing grenades, and the results were very high. When the grenades were all thrown, they started throwing smoke bombs. This thing is more exciting than grenades. After throwing it for more than half a day, no enemy soldiers can pass through the area. Gas mask? After decades of industrial regression, how many gas masks are there? A smoke bomb is enough to block the cave for half a day. The eyes are so hot that the nose and mouth are irritated and coughing. No one can bear this sour taste.

As the underground attack continued to advance, many mechanical soldiers in the caves began to meet, and then joined together to attack the cave hall where more enemy troops gathered.

Open the caves, throw in grenades and smoke bombs, and then close them. After an explosion, open the door and go in to kill the enemy who can't open his eyes and can't see anything. How can you stop the bayonet of the mechanical soldiers by just touching with your hands?

In a cave hall filled with pungent smoke, an enemy officer who was about to pass out with tears and coughing reached out and grabbed around. Suddenly, he grabbed a cold and hard object. At first, the officer thought it was a gun of one of his men, but after touching it carefully, he found that it seemed to be a pair of mechanical legs...

Puff! The bayonet sank into the officer's chest, and then he pulled it out to continue stabbing other enemy soldiers. The mechanical soldiers with no obstruction in their vision slaughtered them easily.

Time passed slowly, and the enemy soldiers who finally couldn't stand being slaughtered underground began to rush out of the exit frantically. The tunnels used to be an invincible magic weapon for them. They used to make the enemy defenseless and exhausted. But now these tunnels not only failed to exert their due combat effectiveness, but became their own hell. More and more enemy soldiers began to run out of the tunnel exits, stumbling in the darkness and trampling to death. I don't know how many people they trampled to death...
