It was the last location, and after it was the truth, "she died really close to the base." Sara said with a frown on her face.

"She couldn't die, she is just a robot, we are too."Tom said.

Sara sighed and nodded, the last location was a huge city, was.

Though compared to other cities this one was intact, the buildings were destroyed but some remained standing. it was only half destroyed, and similar to every remains of a city Sara visited, there was no sign for human life.

"Strange symbols detected!" Tom said and showed Sara many pictures that his scout drones detected, they were red skulls painted in many places of the city, it was found frequently more on destroyed military robots and near big piles of skeletons.

"The enemy is near, preparing battle equipment..." Sara said taking some battle devices.

"Do we have any information about the symbol?" Tom asked.

Sara tried to research the symbol, it wasn't just a skull,it had many smaller symbols inside it.

"Nothing found...It does not matter, my sister probably discovered it."Sara said.

"You always say that, what if your sisters did not figure this out completely?" Tom asked.

"Then I will go out and collect more information.."Sara said. It took many minutes of walking until she found the cube, it was in its shield, and strangely it was not damaged. Not a scratch.

"Did the danger go away?" Tom asked.

Sara checked the cube and shook her head,"I do not know, this cube was launched away from danger before my sister di-...Got destroyed." Sara said and stored the third and final cube in the 'very important' section of her backpack.

Afterwards she approached carefully towards her final destination, an underground base not so far away.

She proceeded with extreme caution, and at the end, just when Sara was a few meters near the base a half destroyed military robot awakened.

Sara quickly took out a special card from her backpack, its function was to let her pass beyond any military robot or any defense system as a neutral robot.

The military robot had four metal legs, though one was missing, it had a rectangular body armed with various weapons, it was painted with dark colors mostly black, it scanned the card then it shoot it evaporating it,"denied...Spare no one."The robot said and readied its weapons.

Sara jumped back and threw a device to the ground, which created a spherical energy armor around herself and Tom.

"What do we do?"Tom asked looking up at Sara.

"We fight, the robot is half destroyed,its defenses were trashed due to previous battles, It is possible to get close and destroy its energy sources. Tom, send out all cat units, you take cover and aid me in combat for afar."Sara gave her order and then the shield was destroyed.

Tom did as ordered, he hid in a safe place, then commanded the defensive units to form a shield around Sara. The offensive units functioned as distraction, they also destroyed most of the projectiles aiming at Sara.

Stolen novel; please report.

Sara acted quick she used her rifle to shoot one of the damaged legs and destroy it, thus further restricting the robot's mobility. She moved around using speed to her advantage.

Even the scout units were helpful, they covered every inch of the battlefield and provided Sara with all the necessary information. Sara then got close, she threw an electric grenade that disabled the enemy weapons. She jumped on the robot and used a cutting machine trying to reach the power source, but she triggered a trap which blew away her arm.

Sara flinched and held onto the robot tightly with her other arm, she commanded the offensive units to make her a new arm, they all fused together making a sharp laser sword arm. The robot moved around going crazy and trying to get her off its back, but even when it managed to hit Sara against a wall she still clung onto it.

Sara used her sword arm to penetrate the robot's heavy armor and stab its power source, she pulled away pulling it along her side, she dropped on her back and looked at the robot,"two more to...go?"She looked confused as the robot lost its energy and fell down.

Now that she got to think of it the robot usually had three energy sources, two main and one for back up, but this one only had a single energy source in its center.

She looked at the source she ripped out of the robot and it was a blue stone from the meteor.

"The uses were secret..Data says it was supposed to be used for peaceful purposes!" Sara said and then she put the rock in her backpack, she still had plenty of space since she used many of the devices she packed.

She called back for Tom, he had lost more than half his cat units. But the mission was over.

Sara entered the Base, she replaced her lost arm and then she activated the computer to analyze the information from the cubes.

Tom went to recharge, later he would turn off himself because the mission was over.

It was the same for Sara. But she refused, she even stopped the automatic solutions and wanted to decide by herself. She recharged herself and waited for the computer to finish analyzing.

It took an entire day for the computer to finally give the answer,and Sara spent every second waiting with anticipation.

"The reason for destruction of all human life is....Humans"Sara read, she read the sentence multiple time then she checked the details.

The first sister's studies showed that the forest was used as an experimental area for many chemical weapons and products which resulted in the mutation of all living beings in it.

The second sister's researches showed that the meteor was attacked. Humans ignored all warnings tried to destroy it to get the energy stones faster and learn how to make them, which caused it to backfire aggressively. This happened with tens of meteors and in the end all of them marked humans as danger. and even using a knife hundreds of meters away would count as an attack and cause the meteor to react violently.

The third sister's findings were the most critical. She deduced that the disaster is.. The third world war. At first it went with very little casualties since the military robots were programmed to cause minimum damage. But it was not enough, thus project 'D.A' was launched, its symbol was the very same one that Sara found. It was used with robots to make it kill everything. Even people in shelters were not safe. Countries with this plan wanted to pressure other countries to give up and end the war quick so they wouldn't have to use too much resources. But even when the opposing countries surrendered the robots did not stop, they continued to attack, and when they finished slaughtering all humans in the enemy countries they went for their own countries and kept fighting until every last human was killed. When humans were all dead, the robots attacked each other trying to satisfy the bottomless thirst for battle.

Sara read feeling sorrow of how humans ended like that,"they do not deserve to live!" Sara screamed so loud, she almost destroyed her voice. Her hands shook violently as she panted, she activated all necessary steps to restore earth. But she did not clone other humans back, she even thought about deleting that possibility.

Yet, she remembered, that not all humans are bad. She researched about how many humans wanted to protect nature, that many humans only wanted peaceful life, that many humans tried to stop this.

And so she decided,"I will give humans their second chance, but I will watch every move they do..And take care of them to prevent them from repeating the same mistakes twice." Later she began working on her plans, hoping that humans in other dimensions are doing well. Hoping that those humans will not do such mistakes, and that they will take good care of their planet, of each other, and of themselves.
