Return of the last survivor

As Merlin was making his way to the building, the people within the building were terrified.

They were all normal residents of the building, going about their normal lives, when suddenly, the world went to hell! People began biting each other and turning into monsters with undying bodies!

All these people could do was wait for help in their own rooms. But none ever came. What came was a single young lady. She had short golden hair reaching her shoulders, and wore clothes as if she had just come out of a military camp.

She went to every room in the entire building and collected all the people alive, while killing off the monsters cleanly using the machete she had.

Nobody questioned why she was prepared for the apocalypse at first, because everyone was too busy trying to survive themselves. Who would have the time to question their saviour.

But as the days past, people began to suspect why she was this strong, and why she was prepared for the Apocalypse.

Just as they were discussing among themselves, she barged into the room, covered in blood, returning from another successful hunt of around 10 zombies. It had been 2 days since she last contacted her little sister, and she was trying to make her way to the police station as quickly as possible. But there were simply too many zombies out there, and all she could do was to slowly kill here way there.

"Phew. It's crazy out there!"

She was just about to put her weapon down and relax, when a particular group of people began to move towards her.

"Hey lady, where did you get those weapons from?"

"Why does it seem like you were prepared for this event?"

"How did you become so strong?"

Once they all said their piece, 5 people stepped out of the crowd, simple weapons like baseball bats in hand.

The lady recognised these fellows. They were the few college students she had run into outside, and had brought back.

"You must be hiding something!"

"It must be your fault!"

"How else do you think she knew about everything?"

These 5 people clearly had accomplices within the crowd, who were instigating them.

The lady clearly notices the 3 shadows moving around within the crowd and badmouthing her.

"Hmph. You have anything to say then get it over with! I will take you on!"

She said while wielding her trusted machete. But just as she was about to make her move, she felt all the mana within the room move to a particular location.

*Whoosh*

Suddenly, a large blue vortex appeared, and it crazily began devouring all the mana within the entire building.

The force of suction was so great that even all the normal people felt gusts of wind flying into the vortex.

Everyone instantly took multiple steps away from the vortex, which seemed to grow bigger with time. From the size of a football, to the size of a door.

Nobody said anything, just stared in terror at the growing mass of energy, as it grow larger and larger.

Suddenly, the flat vortex began changing, almost as if something was pushing it from the inside with incredible force, distorting the flat vortex to a semi-circle.

*Crash*

Suddenly, a window shattered, and a young man rushed in. Everyone's eyes suddenly shifted from the vortex of terror to the youth, who had just jumped in to the 12th floor of the building.

In reality, Merlin could barely jump to the height of the 5th floor of a building with his Tier 1 body. However, If he used mana to boost his legs, as well as Tier 1 Wind magic, he may not be able to fly, but he could most definitely reach the 10th floor of a building.

Just as someone was going to as who the man was, the loud sound came from behind them.

*Crack*

The vortex was finally cracked open by the strong force and a slender grey hand emerged from there, before returning inside the cloak of the person exiting the crack.

No one besides Merlin knew the real identity of the being in front of them, it was a merchant. A trader who had temporarily sealed their strength to that of the maximum level supported by the world, Tier 1.

"Greetings beings of Planet 5118208, I am here to trade on behalf of the Supreme Being"
