In the end, very few humans survived. After the 3rd Cataclysm, about 5000 humans were left with the weakest being the SSSS level.
At that point, anyone below that level could die from the poisonous atmosphere just by merely breathing. Even the atmosphere wasn't forgiving to the beings living through that time.
While about 250,000 people survived and thrived combining all the races, the ones who ruled in the end were the 12 Rulers with each their own special system.
Surprisingly, one of the 12 Rulers was someone who did not possess a system. However, he died in the end since he was the weakest among the 12 Rulers. He was betrayed by the one he loved the most. Oddly enough, he knew, long before he was killed, he knew that he was going to be betrayed and he was merely waiting for his death to come…perhaps dying was what he needed more than living in that world. After all, he had already lost everything at that point…

After making the announcement, a devilish smile creeped up on Zero's face as he calculated the next few steps he was going to take to get everyone out of this facility.
He saw some of the people starting to follow his command while others were still hesitating to move. Though looking at the series of events, it won't be long before they too would start running. After all, who wouldn't like to take the chance to escape from this hellhole.
-Bang Bang
Zero heard a sound from the door.' looks like the security have finally arrived.' He thought as he began running towards the dead bodies of Professor Mark, Richard and Alber and taking out their storage rings.
Checking inside the storage rings, he found a few potions, different types of instruments, some rations. There was another set of guns and bullets, though with the mechanical gun that Zero got from Professor Richard, it wasn't of much use to him.
After that, he took all the food and began hurriedly gobbling the food. He had to make sure he gets as much healing as he can.
Among the thousand ways of survival, the most important one was to make sure that you are in optimum condition. After all, mistakes have higher chances of occurring if you are not upto the mark with yourself. One of the ways of self healing that Zero had learnt along the way was to increase the rate of healing by using the food he eats. Though not as great as a healing spell, it still was good enough to keep him in a working condition under critical situations like this.
-Bang Boom
The door was forced open by the security guards. They were all wearing black suits with guns in their hands. Looking at them, they were all D rank with a combat oriented system.
"Shadow Arts: Guns Slinger's Seventh Shot."
Zero muttered as he attacked the weak points of the guns that the men were holding. Based on his calculation, the gun which he had wouldn't be able to penetrate through the shell of the suits the men were wearing. Even if it somehow does, it won't kill them. So the first thing that he did was to disarm them.
The guns fell apart in an instant and, shocked by the sudden turn of events, the men looked at Zero with more caution than before. They instantly changed their combat stance to hand to hand combat and began charging towards Zero.
'Killing all of them in this state will be time-consuming… let's escape first. The others will find the exit by themselves. It's not that difficult anyway,' Zero thought, taking one last look at the screen before he too began running towards the security guards.
Skillfully dodging their attacks, he kept them under his toes. Their attacks were both smooth and fierce at the same time. Even still, he easily dealt with it as he created an opening to get out of this place.
After creating the opening, he ran through the gaps between the attacks of the security guards and began running outside towards the exit. The security guards watching him escape began running towards him as well.
'Now, the next step is to make sure everyone survives. All right… let's take the detour before moving towards the exit,' thinking that Zero began running in another direction from the previously intended one.
After running for some time, he found a bearded man running towards him. Looking at the clothes of that bearded man, he looked like a person who was captured in this facility.
'Who was he again?....ummm…Ah! It was him, Michael Morningstar, an A rank influential businessman. He was captured here too, huh?' Zero thought as he observed Michael. Michael looked at Zero with a confused look, wondering why he was running away in that direction.
"This way," Zero shouted as he ran across and Michael, watching the guards that were following Zero, also began running in Zero's direction. He wanted to talk to Zero about the situation and other things, but he noticed that no matter how much he ran, he wasn't getting any closer to Zero.
'What the heck?' Thought Michael as he ran behind Zero. Fear was visible on his face, but there was a sliver of hope in his eyes, too. He wanted to live. He had enough of this bullsh*t. He did not know what was going on, but the mere thought of getting out of this hellhole was enough for him to motivate him to run.
After running for a few minutes, they reached a certain door. Zero stopped in front of the gate and began touching the pad right beside the gate. Michael arrived after another half a minute, all huffing and puffing, heavily sweating as he caught his breath.
'What are you doing?' is what Michael wanted to ask, but before he could catch his breath and proceed to ask, a sound interrupted him.

The gate opened and a dumbfounded expression came onto Michael's face as he subconsciously followed Zero inside. What he found inside the gate made his expression turn even more dumbfounded.
The whole room was filled with guns and weapons.
