On the first day of arriving in Tianyin City, Gu Fan led his daughter to visit the steel market. He also bought two steel pillars with a diameter of nine centimeters and a length of about one meter.

"What is Daddy going to do?" the little girl wondered what her father was doing, "Does Dad want to build a weapon that can be used against those annoying relatives?"

"Gee, my girl always comes up with good ideas. Gu Fan said thoughtfully: "Actually, I don't think there is any need to make weapons at all." With these two sticks in your hands, it's already scary. ”

Gu Meng shook his head like a rattle: "No, no, no, if you use a stick as a weapon, people will think that you are a Smecta who eats kimchi." ”

"So, Dad bought this to make merchandise for the afternoon exhibition. Gu Fan smiled and uncovered the mystery for his daughter.

The little girl had a suspicious look on her face: "Where is Dad going to take the things to process?" Mengmeng doesn't think this thing can be brought into the hotel. When the time came, others saw Dad take the round steel in the video, but in the end he didn't take it out. The boss will definitely be suspicious. ”

"Yohe, you even know about video tracking?" Gu Fan said with half relief and half joking: "Girl, I don't remember teaching you this." ”

"Because Meng Meng is a genius!" the little girl looked proud: "Dad, don't forget, there are more than 1,000 episodes of detectives, and Meng Meng never watches in vain." Therefore, according to Mengmeng's inference, Dad has to find another processing site. ”

"Congratulations, you guessed it right, it's worth Daddy to reward you with a Häagen-Dazs, cash it out after dinner. Gu Fan smiled and said, "Let's go, go and see the secret base that Dad found from the Internet." ”

After that, he led his daughter through the streets and alleys, changed a taxi, and then came to a residential area at the junction of urban and rural areas in Tianyin City.

Because it is located at the junction of urban and rural areas, there are no walls and no properties in the community, and all the passages in the area are accessible in all directions. All kinds of criticized infrastructure have become the reason why Gu Fan chose here.

The transportation here is convenient, and it can be attacked and retreated. When you need to evacuate, you can return to the mountains and forests at any time and enter the sea like a tiger, and there is no trace in an instant.

Walking along the road of this residential area, you can see a lonely apartment building at the very back of the community.

In front of the gate of the small building, there is also a camphor tree with lush leaves.

It's just that at this moment, the door of the small building is closed, and the iron lock on the door is also covered with dust, as if there has been no one living here for many years.

"If the information on the Internet is correct, this should have been a bachelor apartment in the past. Later, because the landlord didn't want to take care of it, it was abandoned by water and power outages. Gu Fan put down the round steel and stretched out his right index finger to insert it into the keyhole of the door of the small building.

I only heard a click, and the door was opened smoothly by him: "Okay, do you dare to go upstairs with your father to explore?" It is said that this is one of the eight haunted forbidden places in Tianyin City, a famous terrifying abandoned apartment. ”

"With her father protecting Mengmeng, Mengmeng is not afraid of where she goes?" The little girl was very bold, and she took the lead upstairs without saying a word.

After closing the door, he hurriedly followed his daughter's footsteps upstairs: "Mengmeng, don't go too far, you know? ”

With Gu Fan's master key in hand, the door lock of the entire building is useless.

He picked a room upstairs that was pleasing to the eye, and set up a metalworking factory in the room.

"What is Daddy going to do?" the little girl squatted beside her father, staring intently at his every move.

"It's not me who will do the work, it's your red dragon and blue bee. Stand far away, I'm going to get them up and work. Gu Fan passed the model data he had designed to his two subordinates.

"Long live the Invincible Dragon (Long live the Empress), your will is where we are headed. The two nano-insect armies that received the work order immediately began an orderly metal "cutting process".

For the nanoworms, it is not a hassle at all to devour the metal steel pillar into the shape that the empress wants.

Since they are extremely tiny nanoworms, they can be processed with extreme precision. Even the most advanced CNC machine tool on the planet is still inferior to nanoworms in terms of processing accuracy.

In less than ten minutes, the two round bars had turned into a hundred round steel sheets two centimeters thick.

The round steel section made by the gnawing of the army of nanoworms, each piece is so shiny and shiny, as if it has been polished by the finest sandpaper.

However, dismantling the round bars is only the first step in the job.

Next was the main event, and I saw the army of nanoworms flashing red and blue light, which was instantly divided into twenty teams. Each team carried a round piece of steel and began to finish.

Billions of nanoworms worked at the same time, making an unusually dull buzzing sound.

As they are processed, the iron filings, which are crushed to the nanometer level, also begin to spread in the air. Because such fine dust is harmful to the human body, Gu Fan hurriedly withdrew from the processing room with his daughter in his arms.

"What does Daddy want the Red Dragon Blue Bee to process?" Although the little girl witnessed all her father's actions, she still couldn't figure out her father's plan.

Gu Fan smiled: "It's all gadgets, you'll know when you see the finished product." It's a lot of dust here, so how about Dad take you up to the top of the building to have a look?"

"Okay!" the little girl said crisply: "Now I announce, the haunted house decryption battle starts now! In order to uncover a mystery that has been sealed for many years, Detective Meng Meng and her father's assistant go deep into the abandoned apartment building in one of the eight haunted forbidden places in Tianyin City. ”

"Netizens, don't blink, after the advertisement, the haunted house battle will start immediately!"

Just as the father and daughter were about to go on a haunted house adventure, a gloomy voice came from the stairs: "Meow-"

"Wow-dad help!" Gu Meng threw his head into his father's arms.

Gu Fan hurriedly patted her daughter on the back, and then comforted her daughter softly: "Don't be afraid, girl, with your father here, no one can hurt you." In order to dispel the fear in his daughter's heart, he even used the skills he had learned in the path of evolution.

At the moment when he comforted his daughter, many complex rune marks suddenly appeared on Gu Fan's body.

Countless rays of energy traveled through the formation circuit composed of rune imprints, and in the blink of an eye, a negative energy isolation array was constructed for her daughter.

In the years when he was on the road of evolution, in order to fight against the enemies who had learned magic arcane and Taoist techniques, Gu Fan also had extremely in-depth research on magic, arcane arts, and Taoism on the mysterious side.

Father's comfort seemed to carry an incomparably powerful spiritual power, which made Gu Meng's heart instantly become extremely peaceful. She let go of her little hand that was tightly gripping the hem of her father's clothes, and turned her head to look at the staircase: "Dad, be careful, there are monsters over there!"

"Where did the monster come from?" Gu Fan walked to the staircase with his daughter in his arms: "According to my data analysis, it should be a cat who made the sound just now." ”
