Niu Mei raised her eyes to look at the moon overhead, and continued:

"My father told me a moment before he died that as long as there is a meteorite rain in my city, it means that our earth will welcome an extraterrestrial visitor on this day, and his appearance is to wake me up and bring me the latest instructions from a distant dimension......"

"Visitors from outside the world?" Mai Si and Lan Ruoyu said in unison.

"Yes, I was preparing for class at school when the meteorite rain fell this afternoon, and the sky suddenly turned dark, but our twelfth middle school was not affected by the meteorite rain at all, so I didn't know what was going on until a teacher in our physics group happened to call me to inform me at this time, I didn't pay attention to it after answering the phone, but after a while, I thought of my father's words, and I woke up at that moment.

My father told me that once there was a meteorite rain in the city, I was asked to rush to Luo Miao Mountain in the western suburbs as fast as possible, climb to the top of the mountain, and receive a mysterious mission. ”

"Mom, you're going?"

"Of course, I immediately drove to the western suburbs, but at first my heart was beating, and I always thought it was nonsense, but I was forced to make a promise to my father, and I climbed to the top of the mountain in disbelief until I met a man......

To be precise, it wasn't a person at all...... It's not right, maybe it's a person but it's not us earthlings, how to say it, that person is very short, only half the height of us human adults, and has facial features, but it is different from humans, especially the nose in the center of the face, which is extremely large, and even makes me suspect that it is not a sense of smell at all...... At that moment, I believed my father's words, and this man was the 'Walker'. ”

"Walker?" Maith muttered.

"My father said that the duty of the walker is to contact all the messengers of the heavens and all the worlds, convey the latest information, and assist the guards of each dimension to achieve their mission!"

Mai Si said again: "According to Mr. Niu, this person is equivalent to a postman, but whose instructions is he conveying?" ”

Niu Mei smiled bitterly: "I'm also puzzled by this question!" ”

Lan Ruoyu pondered: "Could our universe really have the existence of the main god?" ”

Niu Mei thought for a while and said: "Maybe there is, maybe not, but our universe is indeed full of wonders, and many things don't make sense with conventional thinking, but when you see is believing, as long as you are sure that it is not a dream, you can't believe it!"

In the case of the Walker, if I don't know my mission, how can I connect the other person with my father's words? His appearance is scary enough, and the language that comes out of that mouth is actually the Haitang Mandarin that I am familiar with, how can you make me embarrassed? ”

"Mom, how did he appear on Luo Miao Mountain?"

Niu Mei muttered: "As an excellent senior physics teacher, my only explanation is that somewhere in Luo Miao Mountain, there may be a space-time tunnel connecting the outer dimensional space, because, by the side of the walker, I have not seen any so-called interstellar travel aircraft. ”

Max: "The energy rice grains were brought by the walkers?" ”

"yes, including the watch I have...... On top of that, he gave me a long, narrow metal box and told me to hand it over to you, the Blue Guard of our Blue Sea Galaxy, and that's what he said. ”

"Where's that thing?"

"I'll put it in the trunk of my car, and it's parked in the parking lot of the Prisoner Bird Bar, so you can pick it up with me."

The trio rushed out and walked along the road on the west side of the ruins towards the Prisoner Bird Bar.

The front of the Prison Bird Bar is still bustling, and the constant flow of people continues to flock to the bar building.

In a weedy open space not far from the Prison Bird Bar, full of all kinds of cars, Niu Mei took Mai Si to the parking lot, opened the trunk, and took out a metal box ten centimeters wide and forty or fifty centimeters long from it.

Niu Mei took it out and rested the metal box on the trunk lid.

Lan Ruoyu turned on the flashlight of her mobile phone.

"Max, you open it yourself."

Max lifted the lid of the box and recognized it as a short knife, now stuck in its scabbard.

Take out the scabbard and hold it very heavily in your hand.

Max pulled out the short knife, but saw that the blade was dull and black, and the blade looked dull and not sharp.

"This knife is ordinary, and it doesn't look like it's outstanding."

Niu Mei took the short knife, her eyes were just focused, and she suddenly sighed.

"Is it a meteoric iron knife?"

"What's the matter?" Maith asked urgently.

"It's forged from high-density meteorite, and I've heard that this kind of knife looks extremely rough and dull, but in fact sharpens iron like clay."

"Really?"

Maith suddenly became excited.

Carrying a short knife, Maith searched around, and in front of him there was a small tree more than one person high, looking at the trunk with a slight force.

"Click!"

A small tree the thickness of a wrist was cut off at the waist.

Look at the blade again, it's still the same as it was.

"Good knives!" Max cheered and continued to look around.

He wanted to find something harder, preferably metal.

He set his sights on a pickup truck.

……

"Mr. Niu, what is my next task? The task issued by the time system is for me to find the tower keeper as soon as possible, but who is the tower keeper and where is he? ”

Niu Mei was about to answer, when her watch visibly vibrate.

"There's a new piece of information." Niu Mei said as she looked down at her watch.

Niu Mei's expression froze, and she said in a low voice: "Lan Wei, there is an latest instruction for you!" ”

"Oh, what instructions?"

"Let you manage to enter the crypt alien race, find the tower keeper, and transfer the seven-horned magic stone safely!"
