Outside the gate of the research institute, the sun was setting in the west, and it was already evening, and the fox fire that had just walked out of the gate immediately screamed.

"My cute FF-I Sword and Shield Angel, who was so ruthless to get its hand off?!"

"It can't be helped, it's so tough that we have to do this. It's okay, you can fix it anyway. Ning Yu picked up a piece of metal that had fallen on the ground, took it in his hand, and threw it up and down.

"No matter how good I am, I can't fix it without raw materials, my poor servant." Fox Huo snatched the metal block from Ning Yu's hand, and cried on the sword and shield angel.

"Please improve your acting skills, no tears came out."

"Hmph, no sympathy. Forget it, let's figure it out when we get back. Fox Fire patted the sword and shield angel who was kneeling on the ground, and took out two things from the bag behind him.

"Little Wind, bring this." Fox Fire threw a black metal box to Chen Lingfeng.

Chen Lingfeng took the box, and inside was a small piece of square silver metal with exquisite workmanship, and it was impossible to tell what material it was made of, wide at the top and narrow at the bottom. He picked up the piece of metal and found it to be very comfortable to hold, fitting perfectly to the width of his fingers, as if it were made to order.

"This is a soldier's assault short knife, although it is a primary weapon, it is much worse than Ning Yu's long sword, but it is enough for self-defense." Foxfire also took out an identical piece of metal from the suspension buckle around his waist.

"This weapon is specially designed for warriors who have animal body cells, and it only needs to be held on the hilt of the knife and held like this." Fox Fire gripped the metal in his right hand, and with a little effort, a silver-white blade shot out from the hilt.

Chen Lingfeng also tried according to the method of fox fire, but no blade popped out.

"Don't worry, it's the first time, you practice slowly, you're a pureblood, you should be able to do it soon." Foxfire smiled and tucked the hilt back into his waist.

"Remember, by feeling, not by you really trying to hold it." Ning Yu said lightly to Chen Lingfeng.

Foxfire took out the folded metal that he had packed up in the research institute from another backpack, put it on the ground and pressed the switch, and the metal began to slowly unfold, it was actually two wide metal plates similar to skateboards, the difference was that there was a small jet engine behind the metal plates.

"Come on, this is my favorite work, the frenzied desert dance, the Flamejet Thruster!" Foxfire began to get excited inexplicably.

"Xiaofeng, come up when you're ready, do you want to stand in front and let me hold you, or..." Fox Fire suddenly had a shyness on his face, "Or do you want to hug people from behind?" ”

Seeing this, Chen Lingfeng immediately turned his face to the side, he still couldn't adapt to the excessive enthusiasm of the fox fire.

"He won't hold you from anywhere, he'll go with me." Ning Yu glared at the fox fire and pressed Chen Lingfeng behind his thruster.

"Oh, you're so ruthless, you broke us apart like this." Fox Huo pouted, and reluctantly took out his goggles and put them on.

"Hurry up, don't look at this thing so small, that guy made a thing, it's very fast." Ning Yu grabbed Chen Lingfeng's hand and put it on his waist.

Chen Lingfeng held on to his slender waist, which was a little dazed for a while, but turned into fright in an instant. Because he saw the foxfire screaming excitedly and rushing out on the thruster, writhing in the air. No wonder Ning Yu didn't let him go with Foxfire. In that way, it is estimated that he will hang up before he reaches his destination.

The two thrusters galloped through the desert and arrived at the location of the fox fire in an hour. This is a gravel area of the Gobi, close to the edge of the desert, and some green vegetation can be seen not far away.

When the three of them arrived at their destination, it was already nightfall, and after discussion, Ning Yu decided to wait until dawn before acting. A few people set up a simple tent, hurriedly ate some food and prepared to rest, during which the fox fire couldn't help but tease Chen Lingfeng. It didn't stop until Ning Yu knocked her head a few times.

There was nothing to say all night, and the next morning, the fox fire got up again in disheveled clothes, and the exquisite curves outlined a charming charm.

When had Chen Lingfeng ever seen such a situation, the hormones emitted by a mature woman's body caused him to almost spurt a nosebleed.

"I don't even know how you grew so big, you used to eat the same things." Ning Yu hurriedly took his clothes and put them on Fox Fire.

"What, you're envious?" Fox Huo stretched lazily, and deliberately shook his body in front of Ning Yu.

"I, one, point, all, no, envy, admiration!" Ning Yu replied word by word, and she felt that her blood pressure had increased a lot.

The three of them packed up, and Foxfire pulled out a tablet-like handheld device from his backpack, and his fingers kept clicking on it. Soon she was on target.

"There's nothing here." Chen Lingfeng looked around, but he didn't see anything except stones and yellow sand.

"Some things are not seen with your eyes, this is the entrance to the energy pipeline, from the slums to Yaoguang City, it is something that is located in another field." Foxfire lifted the device in his hand into the air, and a blue pillar of light emanated from the device, and then the device's display was decoded with complex formulas.

It didn't take long for Chen Lingfeng to see that the space behind the pillar of light began to fluctuate, undulating as regularly as an ocean. Soon a large black pipe emerged from the space, and it appeared out of thin air without warning.

The black pipe is diagonally inserted into the air, with no end in sight, and next to the pipe is a maintenance ladder for people to walk on.

"Alright, let's go." The fox fire set the parameters on the device and passed through the undulating space.

Chen Lingfeng also walked over, and through the space, he clearly felt that he had entered two worlds. Outside, the Gobi Desert became blurry, and the sound of wind and sand blowing was completely inaudible.

"Yaoguang City is a world built in the cracks of space, these things are not yet incomprehensible to you, in short, it is like a portrait of the original world projected in a mirror. It's a separate space. Foxfire stood on the escalator and looked at the pipe that had sunk into the sky.

Chen Lingfeng gradually began to be somewhat immune to these things beyond his cognition, and turned from his original surprise to curiosity, asking Fox Fire about Yaoguang City along the way.

After walking for a long time, the ground was blurred, and the three of them seemed to be in the clouds, following a staircase to heaven. But soon there was a slight change in the air, and some harsh noises could be heard from afar.

"Hmph, the slum guards have come to meet us." Foxfire said, staring at the sky outside the escalator.

Some black dots swooped down from the sky from far and near, and the speed was extremely fast, and Chen Lingfeng gradually saw the appearance of those things clearly.

They have fleshy wing membranes with large sharp claws obliquely growing on the protrusions on the wing membranes. The protruding mouth occupies three-quarters of the face, and the staggered teeth glow with a cold white light. Like a giant flying squirrel, he lunged at the three people on the escalator.

"It's been a long time since I've been active, so I'm just going to warm you up." Fox Fire took out a short knife with a red body from his close-fitting backpack, the process and structure were exactly the same as Ning Yu's weapons, except that the blade exuded the aura of scorching flames, just like Fox Fire himself.
