Two hours later.

Three hundred and forty-two candidates, riding a giant lift, continued to march deep underground.

The elevator is like a giant metal disc, relying on an anti-gravity rune array, gliding silently through the darkness.

The balance array at the edge of the disc emitted a faint blue light, reflecting the exhausted faces.

For more than ten hours in a row, the brain was running at a super high speed, and even if the candidates were all powerful cultivators, they were a little overwhelmed.

The candidates were clearly divided into two groups.

340 candidates sit on the outside of the large disc to form a large circle.

At the center of the circle, there are only two candidates.

Li Yao and Jiang Shaoyang.

The crazy expression of the two monster level shocked everyone, and everyone involuntarily stayed away from the two, for fear of disturbing the duel between the two monsters.

It's like in the flood hundreds of millions of years ago, the two Tyrannosaurus rex are facing each other, and there will be no living beings who dare to stand in their way.

After a while, everyone's eyes were full of flowers.

The elevator finally broke through the darkness and sank thousands of meters underground.

And the majestic scene in front of them made everyone's breath stagnate.

They were in the middle of an incomparably large underground cavern.

Looking up, it was hundreds of meters away from the top of the cave covered with stalactites.

Looking down, it was still dark and dark, and I couldn't see the bottom at all.

Looking around, the cylindrical karst cave is more than a kilometer in diameter, and the surrounding rock walls are covered with thousands of caves that have been dug by hand.

The hive, here is like the inside of a giant steel hive.

And they are nothing but the tiniest ants.

Even the giant elevator, after sinking into the cave, turned into a lonely boat, surrounded by countless faintly glowing metal discs. It was a busy scene.

"This is the power of the state!"

"Only by mobilizing the strength of one country and tens of billions of people can we build such a magnificent world underground!"

"Only this kind of power can compete with the hundreds of millions of demons in the endless sea of stars!"

Li Yao sighed in his heart, while realizing that he was small, he was also a member of such a powerful country. And feel deep pride.

The disc slowed down, flying towards a rock wall that reflected a metallic sheen.

Two firefly-like dots of light floated up from the abyss underground, flying to the side of the disk.

But it was two soldiers with metal wings on their backs.

The two soldiers each held a magic weapon in their hands, emitting a red light that enveloped the large disc.

"Didi!"

The blinding red light turned a soft green, and everyone's identities were checked.

On the rock wall, outside the hundreds of caves dug by hand, there were originally cold metal gates blocking them, but they all slid open silently.

The large disc rises and falls. Send everyone to the corresponding cave according to the test number.

Li Yao took a deep breath and strode into his own cave, the metal door slowly closing behind him.

It's the last level!

Li Yao looked at the cave curiously, he was very familiar with the furnishings around him, this was a maintenance workshop, and there was a small refining room and a material warehouse in the back, although the sparrows were small. Everything you need.

"Didi!"

The exam crystal brain sent out the message, the questions of the actual combat test session. It is to use the facilities and raw materials in the maintenance workshop to repair a puppet war beast within 24 hours, so that it can restore at least 90% of its combat effectiveness.

"Repair type tasks?"

Li Yaole is happy, didn't he just hit the muzzle of his gun?

In the corner of the maintenance workshop, a small group of objects is covered with oilcloth. Li Yao opened it, but his eyes lit up.

"Phantom wolf?"

The puppet war beast, similar to the "Wooden Ox Flowing Horse" that Li Yao repaired in the small mountain village a year ago, is a kind of artificial spirit weapon that uses a crystal brain to control zhì and has a certain ability to act independently.

Phantom wolf. It was a puppet war beast that the Valley of Wolves had refined thirty-three years ago.

Because of its excellent design and excellent performance, it was purchased in large quantities by the military.

This kind of puppet war beast, using the principle of bionics, the design refers to the appearance characteristics of many wolf and leopard monsters, the whole body is long and narrow, streamlined, agile, fast, adaptable to a variety of complex terrain, especially suitable for grassland and jungle battles, even on steep rocks, can climb freely.

The phantom wolf is a light war beast, with a body length of 1.46 meters and a total weight of 156.33 kilograms, and is equipped with a light crystal magnetic cannon on both sides of the body, and a flying sword launch system can also be attached to the abdomen, carrying twelve miniature flying swords, which greatly enhances the long-range firepower.

In addition, at the ends of its front and rear limbs, four concussive claws are made of super-strong alloys, and the biting force of the full mouth of steel teeth is also extremely strong, and there is a flamethrower in its throat, which can shoot out a flame stream of more than 1,000 degrees under the drive of the flame rune array, turning the enemy into ash in an instant.

Phantom Wolf has two combat modes.

It can be controlled remotely by soldiers or cultivators at close range.

You can also enter the general objectives in advance, such as "patrol", "guard", and "free hunt", and then the crystal brain built into the phantom wolf controls zhì and fights on its own.

As soon as the phantom wolf appeared, it immediately replaced the status of many military canine spirit beasts and became the favorite of the military, especially scouts.

To this day, a standard reconnaissance team in the military consists of two scouts and a phantom wolf.

However, the phantom wolf in front of Li Yao is in a bad situation.

It seemed that from a long distance, it ate an acid attack from the demon beast, and the metal shell was corroded to the point that it was full of holes, and many crystal wires connecting the vital points were corroded and broken.

Then he started hand-to-hand combat with the ferocious demon beast, the side of his head was deeply dented, his body was torn apart, and three of his four legs were broken, and between two of his front legs and his body, only a few poor crystal wires were still connected.

A shocking hole was even pulled out of the abdomen, and many of the chips and organs engraved with the key rune arrays were gone, and the rest were also mottled and ineffective by acid corrosion.

Except for a vertebrae made of special alloys, which were still intact, the phantom wolf was almost on the verge of obsolescence.

For Li Yao, this is a commonplace scene.

Both in the Dharma-Treasure Grave. Still in the ruins of the refining department of the Great Wilderness War Academy, 90% of the magic weapons are on the verge of being scrapped, or even completely scrapped.

So what?

It's not that he's repaired it little by little, and it's even stronger than before.

This phantom wolf is far from the most tattered magic weapon he has ever repaired.

Li Yao rubbed his hands together and concentrated. Engaged in intense maintenance work.

The first step is to disassemble all the components of the phantom wolf to see which ones can be kept, which ones must be repaired, and which ones have no value for repair, so they can only be refined.

"Huh?"

When Li Yao spent eleven minutes to complete 80% of the dismantling work, he suddenly discovered a very hidden problem.

In his hands, there is the intact vertebrae of the phantom wolf.

But the sound of friction between the joints made him feel a subtle strangeness.

He didn't hesitate. Fold your fingers and flick them towards the twenty-second vertebrae, listening carefully to the sound of metal concussions, sketching an intricate profile in your mind.

"Twenty-second vertebrae, there's a problem!"

"Although it looks intact on the outside, it has been hit several times by strong impacts, and the interior has long been covered with tiny gaps that cannot be seen by the naked eye, reaching the limit of metal fatigue!"

"Just one more high-speed impact. No, no impact. As long as this phantom wolf makes another emergency stop and change direction in the ultra-high-speed movement, this bone will completely burst! ”

Wolves, there is a copper-headed iron-tailed tofu waist, and the waist is a fatal weakness.

The same is true for the puppet war beast of the phantom wolf, which has a streamlined body shape in order to pursue speed and flexibility. The lower back, which connects the front and back of the body, is also the most vulnerable part, almost supported by the vertebrae.

And unlike the wolf demon beast, the phantom wolf also has crystal magnetic cannons hanging on both sides of its body, and the recoil when firing will also bring huge pressure to the waist.

And the twenty-second vertebrae. It is right at the waist, which is the key to the key, once it bursts, it is equivalent to paralysis of the lower body, and it instantly loses 95% of its combat effectiveness!

"Looks like it's a trap."

"At first glance, this phantom wolf is riddled with holes, fragments, and bruises all over his body...... But these are minor problems. ”

"This invisible dark wound is the real fatal wound!"

"If you patronize the maintenance of those injuries on the surface, and ignore the dark injuries of the vertebrae, even if the appearance is new, it will not be able to withstand the test of actual combat, and when you get to the test field, you can do a few high-speed maneuvers casually, and your waist will be broken!"

Li Yao smiled slightly, since he found the problem, it would be easy to deal with it next.

He double-checked to make sure there was only one trap, and then went into the material warehouse to look for the materials needed for the repair.

Soon, he discovered a second fatal problem.

"It's not Zijin Titanium, it's ...... Associated purple gold titanium! ”

Zijin titanium is a rare metal, which is a special alloy used in refining the vertebrae of phantom wolves, an indispensable raw material, which can greatly improve the strength of special alloys.

The associated purple gold titanium is a very strange associated metal in the purple gold titanium ore.

Although the appearance, color and texture are almost the same as those of real purple gold titanium, there are some differences in properties, and the strength of the alloy cannot be improved at all.

There are some associated purple gold titanium stored in the material warehouse, but there is not half a gram of real purple gold titanium!

"Is this another trap?"

"To test the candidate's eyesight, see if we can distinguish between Zijin titanium and the associated Zijin titanium?"

"Without Zijin Titanium, there is no way to refine new vertebrae."

Li Yaopan sat in the center of the material warehouse, his fingers lightly tapping the ground, thinking quietly.

In the monitoring room, the three examiners looked at a candidate who was grinning and pondering, and they all showed strange smiles.

"You say, among the more than 300 candidates, how many of them can find the trap on the spine of the phantom wolf, and even if they do, how long will it take to realize that we are providing the associated purple gold titanium, but 'forgetting' to provide the real purple gold titanium?"

Dong Liuqi asked with a smile.

Yan Tianhe smiled slightly, and was about to speak, when a light curtain in the center suddenly flickered.

There is a test taker who makes a call request.

"Excuse me, why is there no Zijin titanium in the material warehouse that is necessary to repair the phantom wolf?"

In the light curtain, Jiang Shaoyang asked very calmly. (To be continued......) R1292
