It’s the end of the world after becoming a mountain god!

After making sure that Song Tang did not catch up, he first put the bag, which was almost as tall as himself, into the ventilation duct, and then climbed up flexibly with his hands.

Song Tang continued to follow behind and found that the girl jumped from one of the openings.

When I looked down, I saw a bank vault underneath.

What a great place!

Song Tang did not follow, but continued to stay in the ventilation duct.

After meditating all night, I heard a noise coming from below. Soon I saw the girl climbing up from below with the huge backpack on her back.

Song Tang thought about it and continued to follow the girl quietly.

The girl was just like she did yesterday, basically going into every house she saw and taking a look around.

But today she was obviously not as lucky as yesterday. After wandering around for several hours, her backpack was still empty. She probably didn't find anything useful.

The girl looked frustrated, but she quickly gathered herself together and continued walking towards the next house.

Obviously, the girl's bad luck did not end there.

Right in front of the girl, a cockroach as big as a round table appeared. When it saw the girl, it spread its wings and began to vibrate at a high frequency.

"Don't come over here!" The girl was obviously frightened and her face turned pale in an instant.

She looked around and quickly picked up a cement block that weighed about 100 to 200 kilograms.

The cockroach has revealed its long upper jaw, which looks like two fangs, and it flaps its wings, creating a gust of wind.

Seeing the cockroach attack, the girl threw the block of cement in her hand directly, hitting the cockroach's head accurately.

The cockroach shook its head vigorously after being hit, but it did not cause much damage. The girl seized the opportunity and turned around and ran away.

Song Tang put the half-drawn sword back into the sheath. She glanced at the obviously angry cockroach and quickly caught up with the fleeing girl.

I had only run a few dozen meters when I saw the girl stopped by the road again, and a giant mosquito flying in a triangle in front of her.

The girl wanted to run back, but when she turned around, she saw the cockroach chasing her angrily, her pale face completely drained of color.

Her eyes were filled with fear, and her lips were bitten so tightly that they were almost bleeding.

"Alas——" Song Tang sighed heavily.

This child's luck is amazing. It's unlucky to say that there are almost no living people in the whole city, but she is still alive and well.

She is lucky, but there are wolves in front and tigers behind, and it seems like a dead end no matter how you look at it.

Now surrounded by four mutant creatures, the girl looked very scared but had no intention of giving up.

She clenched the axe in her hand, looking as if she was going to fight to the death.

Song Tang took off the talisman on his body and pretended that he had just walked out of an abandoned house.

Seeing the girl still showing a look of shock: "What a coincidence, why are you here?"

girl:"……"

When she saw Song Tang appear, the girl showed a moment of surprise on her face. But she quickly turned her back to Song Tang and faced three mosquitoes as big as large dogs.

She raised the axe high, shouted and rushed towards the three mosquitoes.

"Leave it to me." Song Tang held her shoulders, "Hide and protect yourself."

It seemed that she didn't expect Song Tang to really help. The girl stared blankly at Song Tang, who was half a head taller than her.

It was not until Song Tang urged her again that the girl took a deep breath and handed the axe in her hand over forcefully: "Here you go!"

"Give it to me?" Song Tang stretched out his hand. The girl immediately looked painful and reluctant, but she did not take it back.

Song Tang pushed the axe back, raised the sword in his hand, smiled and said, "I have it."

"This thing has very thick skin and tough flesh. Your sword looks beautiful, but it will probably break after one cut." The girl said as she handed the axe forward again.

Song Tang drew out his sword and pointed the tip of the sword at several mutant creatures that had been wary of her but had not approached her.

Pretty smart! He even knows to observe first.

"You'll know if you try it." After Song Tang said that, he pointed his toes and moved easily to the three giant mosquitoes as if flying.

The girl looked at Song Tang who was fighting with three mutant mosquitoes, and then looked at the axe she had not sent out.

She turned around and looked at the mutant cockroach that had been eyeing her hungrily, gritted her teeth, raised the axe high and rushed over.

Song Tang killed three giant mosquitoes with just a few swords. When he turned around, he found that the girl was pinned down by a giant cockroach, with its long mandibles stabbing at her head with every bite.

The big axe in the girl's hand was struggling to support the giant cockroach's head.

Song Tang kicked the cockroach away, then chased after it and chopped it in half with a sword.

Return to the girl and help her up from the ground.

She looked at Song Tang with sparkling eyes, pointed at the cockroach whose legs were still moving, and asked excitedly: "You, you, what kind of superpower do you have? You are so good at killing mutant creatures!"

Superpowers? What are they?

Song Tang was silent.

"Oh—" the girl let out a long "oh" and said with a look of understanding, "Keep it a secret! I understand! Such a powerful ability really needs to be kept secret, otherwise it will be easily coveted by others."

The girl took the initiative to find a reasonable excuse for Song Tang, and then ran happily to the corpses of several mutant creatures.

She used the axe to dig there for a while, secretly envious as she did so. If she were as good as him, she would have left here long ago.

"Found it!" the girl exclaimed and took something out of the sticky liquid.

He carefully brought these things back and took out a white T-shirt with several footprints on it from his backpack.

After wiping the stuff clean carefully, I found three white crystal-like things, each about the size of a thumb.

Song Tang squatted beside the girl. Because he was close, he could clearly smell a strong fishy odor coming from the thing.

She asked with disgust: "What is this? Why did you pick it up?"

"The crystal core." The girl said as if it was a matter of course. She dug out a cleaner towel, wrapped the crystal core up and put it on her backpack.

She ran to the dead cockroach again, and soon the girl returned to Song Tang again, her face full of regret.

"Such a powerful and big creature doesn't even have a crystal core!" But soon the girl smiled again, looking up at Song Tang, "But it doesn't matter, it's already amazing that four mutants got three crystal cores."

The girl picked up the crystal core on the backpack, wiped it carefully, and then handed it to Song Tang carefully, "This is your trophy!"

Song Tang pursed his lips and repeated the question, "So what is a crystal core?"

This time it was the girl's turn to be confused. She looked at Song Tang in shock: "This thing is called a crystal core. Some mutants have it, and some don't. Different levels of mutants have different colors of crystal cores and contain different energies. But I've only seen white and green ones, so I don't know what higher-level crystal cores look like."

Thinking back to the first time she saw the green crystal core, the girl's face showed surprise, but more of fear.

It was that green crystal core that triggered everyone to kill each other.
