In the underground square, which is as bright as day, people in various costumes, or holding folders, are writing and drawing on paper while walking, sometimes frowning, and there are also people holding test tubes, constantly shaking, looking nervously at their reactions, or holding metal blocks, walking cautiously, afraid of falling this precious metal block......

The people here seem to be busy, walking through the square in a radius of ten feet.

The dome is round, the square on the ground is also circular, covering an area of broken wide, and there are thirty-six passages around it, only a few passages are different, and the rest of the passages are all in and out.

"Did we come to a scene that only happens in a movie?" Qin Wu was very curious, timid, and hid behind Li Jia.

Rao is Qin Wen, he was a little restrained, and looked around silently.

Isn't that so? In the movie scene, the underground research institute that will appear is intuitively presented in front of their eyes.

"Remember where we came out of the cave," Shi Feilong said with a smile.

The four of them subconsciously turned around and saw the round arch behind them, with the word 'one' written on it.

"Isn't this one, it's still capitalized," Qin Wu said with a pout, and then swept to the words above the other round arches, 'two', 'three', 'want', and 'three picks up the land'.

There are thirty-six round arches, they have their backs to the opening of the number one, and the numbers are arranged in a counterclockwise direction.

The people here were very busy, they didn't deliberately communicate with people, they didn't want to waste time, and some people looked up and saw Shi Feilong and the others, at most they just nodded their heads, and they didn't even make a sound.

Shi Feilong walked in front of him, and led the four people to the entrance of the Nine Horn Cave, and when he walked four or five meters, there was a layer of light curtain visible to the naked eye.

The light curtain was like water, as transparent as glass, similar to the invisible prohibition outside the Spirit Mountain, and the scene behind it could be seen, it was a heavy metal door, closed tightly; Qin Wu was very curious, jumped forward, stretched out his white and tender little hand, and was about to touch it.

Seeing this, Qin Wen hurriedly pulled back his sister, Qin Wu, who was in mid-air, sat on the ground. For some reason, Qin Wen sensed a dangerous aura from the light curtain.

Actually, Lieyang Mountain and Shi Feilong were ready to make a move, but they were far away from Qin Wu.

"What's wrong, brother!" Qin Wu was very dissatisfied, his little buttocks were almost broken, and it hurt a lot.

"Dust off your body" Qin Wen pulled up the little girl and explained: "Maybe I'm too worried, after all, in many movie plots, this kind of thing is composed of lasers." ”

"You are very cautious, be careful to sail the ship of ten thousand years" Shi Feilong nodded, obviously appreciating Qin Wen, and said: "This is the newly developed electromagnetic light curtain, emitting lasers, the temperature is extremely high, and gold fossils can be melted;

Lieyang Mountain was silent, which also reflected from the side, no matter how high the kung fu was, he was also afraid of hot weapons, and he reacted that a dangerous weapon like this may also have many limitations, perhaps because of the high energy requirements, or because it is difficult to move, and it is also difficult to take the initiative to kill the Soul Snatcher, at most he can only defend passively.

Li Jia looked outside the light curtain, frowned and asked, "Then how do you get in and out? There is no control switch here!"

Shi Feilong snorted lightly, his body was filled with blood, enveloping himself, and his blood and qi gathered into an illusory Jia Kai, his clothes and beard were tightly attached to his body; he was silently reciting the cultivation method, the blood and qi energy belonging to the strong man rippled, and the air around him seemed to be emptied, and the four of them all felt depressed, and their breathing appeared temporarily unstable; as they each silently recited the cultivation method, this was much better.

Shi Feilong walked towards the light curtain, and the blood light armor on the surface of his body came into contact with the electromagnetic light network, making a sneering sound, and the two energies canceled each other, corroded, and consumed each other.

The LED lights on the aisle are on and off, the light and darkness in the passage alternate, the electrical energy is extremely unstable, and the light curtain is blazing, eroding the blood light outside the body of Shi Feilong with all its might, which looks extremely dangerous.

This made everyone sweat secretly, worried that Shi Feilong would be burned to ashes.

Fortunately, this fourth heavenly dragon of the Huaxia Dragon Group, his physical body cultivation is quite strong, his cultivation level surpasses everyone present, and he has the strength of the innate realm, and the blood light on his body is always rich, and he looks quite relaxed, so he cancels out the light curtain of the electromagnetic network.

He walked in safely, about three meters through it, before he completely passed through the range of the light curtain attack.

On the wall to his side, an electronic screen was inlaid with a faint fluorescence.

Shi Feilong withdrew his qi and blood fluctuations, his face was slightly pale, obviously it was quite difficult to pass through this passage just now.

This can see the hearts of the four people, if the Tianlong master wants to pass through the electromagnetic light network, it is so difficult, then the things guarded inside must be extremely valuable.

On the fourth day, the dragon raised his hand, entered his fingerprint on the electronic screen, lit up the screen, and wrote a series of numbers, letters, and words by hand.

Finally, he took a deep breath and pressed a key that didn't exist. The energy light curtain channel, which was about three meters long, lost its energy supply and disappeared in an instant.

"Come here," Shi Feilong waved.

Lieyang Mountain walked over first and came to his side, and seeing that this big man passed unharmed, Qin Wen and the three of them walked over.

After all four of them passed, Shi Feilong re-entered his fingerprints and password on the electronic screen, restarted the electromagnetic optical network, and turned on the defenses.

"What's in there, so secret!" the four of them were curious, and asked the Fourth Heavenly Dragon.

Shi Feilong was very proud, and continued to walk forward with the people, and said with a smile: "The things inside are the latest scientific research results. You should have seen King Kong Iron Man, right? The combat uniform inside is very sci-fi and magical, and we have also researched it, and used the 'spirit gold' in the spirit mountain as a carrier to create similar armor!"

The eyes of the four people are hot, this is about to issue combat weapons?

"Actually, steel armor is not difficult to manufacture, the difficulty is energy conversion, and the reduction of volume, even with nanotechnology, it is difficult to do" Shi Feilong sighed, paused slightly, and said: "However, in the Spirit Mountain, there are all kinds of mysterious metals, which seem to have been bred for a long time, and are the best carriers that can be found at present, we call it 'Spirit Gold', which is why we have that kind of armor;

"Is there still this kind of metal in the Spirit Mountain?" Qin Wen's eyes lit up, if there were more of this metal, would it bring substantial changes to Xingzhou, which made him look forward to it, after all, after the green jade stone was devoured by Ah Qi last time, he obtained the cultivation method of 'Innate Origin Qi'.

He has also seen the movie, wearing that kind of magical armor, it can fly to the sky, spit out flames and cold, stimulate energy cannons, and even hide on the body, use it as you like, and change shapes.

"It's still in the research stage, and only the dragon king can use it in the dragon group, but that armor doesn't have much effect on the dragon king," Shi Feilong said, as if pouring a basin of cold water to extinguish the flames in everyone's hearts.

On the fourth day, the dragon opened the metal door, revealing a room behind it, which was brightly lit and lined with several rows of hangers, as if he had arrived at a clothing store.

Clothes and trousers of various colors were hung on it, which glowed in the light, and at the edge of the room were racks of weapons with eighteen weapons.

"This is the preparation room, which contains combat uniforms and weapons," Shi Feilong explained with a smile, "You can choose a complete set at will, and be fully prepared for the next demon slaying." ”

The clothes and pants on the shelves are made of amazing material, similar to steel armor, mixed with some spiritual gold, excellent quality, and extremely high flexibility; according to Shi Feilong, even pistols, rifles and other hot weapons cannot be shot through.

According to his explanation, this kind of combat uniform can resist the attack of cultivators in the early stage of the Spirit Realm without damage, but the disadvantage is that it cannot offset the impact force, and it needs to resist hard; he warned the four of them that their own strength is the real strength, and relying too much on external objects will affect their own development.

When you are strong, it is not a problem to catch bullets with your bare hands and tear the king with one hand, that is really powerful.

The material of the combat uniform is the same, but there are also high and low, which is different from the proportion of spiritual gold mixed with it.

Shi Feilong was very serious about these four people, especially Qin Wen was the Lord of the Spirit Mountain, who contributed so many cultivation places, he personally selected the four best combat uniforms, which were almost mixed with fifty percent of the spirit gold, and handed them to the four of them.

The steel armor, which was made entirely of spiritual gold, was only in the hands of the Dragon King, and no one else could use it, not even the First Day Dragon.

It's not that I don't want to build a second Jiakai, but the main reason is that the technology is immature, and it is completely a chicken rib product that cannot be promoted;

Lingjin is still a scarce metal.

The four of them excitedly took over the combat uniforms, each chose a changing room, and began to change.
