40,000 Years of Cultivation

Two hours later.

Three hundred and forty-two candidates took the giant elevator and continued to march into the deep underground.

The elevator is like a huge metal disc, relying on the anti-gravity rune array, gliding silently in the dark.

The array of balance symbols on the edge of the disc emits a faint blue light, reflecting the exhausted faces.

For more than ten hours in a row, the brain has been operating at super high speed, even if the candidates are all powerful cultivators, they are somewhat overwhelmed.

The candidates were clearly divided into two groups.

340 candidates sit on the outside of the big disk, forming a big circle.

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

Li Yao and Jiang Shaoyang.

The crazy performance of the two monsters shocked everyone, everyone involuntarily stayed far away from the two, for fear of disturbing the duel of the two monsters.

Just like in the great famine hundreds of millions of years ago, the two Tyrannosaurus rex are facing each other, and there will not be any creatures who dare to stand in between them.

Suddenly, everyone saw a flower.

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

But the majestic and magnificent scene in front of him makes everyone's breathing stagnant.

They are in a huge underground cave.

Looking up, it is hundreds of meters away from the top of the cave full of stalactites.

Looking down, it was still black and black, and I couldn't see it at all.

Looking around, there is a cylindrical karst cave with a diameter of more than one kilometer. The surrounding rock walls are covered with thousands of artificially excavated caves.

Honeycomb, here is like inside a huge steel honeycomb.

And they are just the smallest ants.

Even the giant elevator turned into a solitary boat after sinking into the cave, and there were countless luminous metal discs flying around, showing a busy scene.

"This is the power of the country!"

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

"Only this kind of power can compete with the billions of monsters in the endless sea of ​​stars!"

Li Yao sighed in his heart. At the same time he realized his insignificance, he was also deeply proud of being a member of such a powerful country.

The speed of the disc slowed down and flew towards a rock wall reflecting the metallic luster.

Two firefly-like light spots floated from the abyss below ground and flew beside the disc.

It was two soldiers with metal wings stuck in their backs.

Each of the two soldiers held a magic weapon in their hands, emitting red light, covering the big disk.

"Didi!"

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

On the rock wall, outside the hundreds of artificially excavated caves, originally sealed by cold metal gates, all of them slid open silently at this time.

The big disk rises and falls, sending everyone to the corresponding cave according to the test number.

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

The last level!

Li Yao looked at the cave curiously. He was very familiar with the surrounding furnishings. This was a repair shop, with a small mixing room and a material warehouse behind it. The sparrows were small but well-equipped.

"Didi!"

The test crystal brain sent a message. The question of the actual combat test link is to use the facilities and raw materials in the repair shop to repair a puppet war beast within 24 hours to restore at least 90% of its combat effectiveness.

"Repair-type tasks?"

Li Yaole is now, isn't this just hitting his muzzle?

In the corner of the repair shop, a small group of things was covered with oil cloth. Li Yao opened it, but his eyes lit up.

"Illusory Wolf?"

The puppet war beast, similar to the "Wooden Cow and Flowing Horse" that Li Yao repaired in a small mountain village a year ago, is a man-made psychic weapon controlled by a crystal brain and capable of autonomous action.

Illusory Wolf is a kind of puppet war beast refined by Wolves Valley 33 years ago.

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

This puppet war beast uses the principle of bionics and refers to the appearance and characteristics of many wolf and leopard monsters. The whole body is long and narrow, streamlined, agile, and extremely fast. It adapts to various complex terrains. It is suitable for fighting in the grassland and jungle, and can climb freely even on steep rocks.

The phantom wolf is a light war beast with a body length of 1.46 meters and a total weight of 156.33 kg. It is equipped with a light crystal magnetic cannon on both sides of the body. A flying sword launch system can be attached to the abdomen. It carries 12 mini flying swords, which is greatly enhanced. Long-range firepower.

In addition, the ends of its front and rear limbs are made of super alloy with four shock claws. The mouthful of steel teeth has a strong bite force. There is also a flamethrower in the throat, driven by the flame array. , Can blast out a stream of inflammation over a thousand degrees, instantly turning the enemy into ashes.

The magic wolf has two combat modes.

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

You can also input general targets in advance, such as "patrol", "guard", and "free hunting", and then control by the built-in crystal brain of the magic wolf to fight on its own.

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

Today, a standard reconnaissance squad of the military consists of two scouts and a magic wolf.

However, the situation of the phantom wolf in front of Li Yao's eyes was a bit uncomfortable.

It seems that from a long distance, after eating an acid attack from the monster beast, the metal body was corroded and riddled with holes, and many of the crystal wires connecting the vital points were corroded and broken.

Then he started a hand-to-hand fight with the ferocious monster beast. One side of his head was deeply sunken, and his body was torn apart. Three of the four legs were broken. Between the two front legs and the body, only a few pitiful crystal lines were still connected. With.

A shockingly large hole was pulled out of his abdomen. Many of the chips and organs engraved with the key symbol array were all missing, and the rest were mottled by acid corrosion and did not work well.

Except for a spine made of special alloys that is still intact, this magic wolf is almost on the verge of being scrapped.

For Li Yao, this is a commonplace scene.

Whether in the tomb of the magic weapon or in the ruins of the refining system of the Great Desolate War Academy, 90% of the magic weapon is on the verge of being scrapped, or even completely scrapped.

so what?

It hasn't been repaired by him bit by bit, even stronger than before.

This fantasy wolf is far from the worst magic weapon he has ever repaired.

Li Yao rubbed his hands, concentrated himself, and devoted himself to the intense maintenance work.

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

"what?"

When Li Yao spent eleven minutes and completed 80% of the disassembly work, he suddenly discovered a very hidden problem.

In his hand, the spine of the phantom wolf was intact.

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

Without hesitation, he folded his fingers, flicked towards the 22nd spine, listened carefully to the sound of metal vibrations, and sketched out an intricate cross-section in his brain.

"The twenty-second spine, there is a problem!"

"Although the exterior looks intact, it has been subjected to several strong impacts, and the interior has long been covered with tiny gaps that the naked eye can't recognize, reaching the limit of metal fatigue!"

"As long as there is another high-speed impact, no, there is no need to impact, as long as this magic wolf performs a sudden stop and change direction in a super high-speed motion, this bone will completely burst!"

For the wolf, there is a saying that the waist is a fatal weakness.

The same goes for the puppet war beast like the Phantom Wolf. In order to pursue speed and flexibility, the body is streamlined. The waist that connects the front and back of the body is also the most vulnerable part, almost relying on the spine to support it.

And unlike the wolf monsters, the magical wolves also have crystal magnetic cannons hung on both sides of their body, and the recoil when firing will also bring huge pressure to the waist.

And the twenty-second spine, right at the waist, is the key point. Once it bursts, it is equivalent to paralysis of the lower body and instantaneous loss of 95% of its combat effectiveness!

"It seems that this is a trap."

"At first glance, this phantom wolf is riddled with holes, fragmented, and bruised...but these are all small problems."

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

"If you pay attention to repairing those injuries on the exposed surface, but ignore the hidden injuries of the spine, even if you look new, you can't stand the test of actual combat. When you get to the test field and do a few high-speed maneuvers, your waist will break!

Li Yao smiled slightly. Now that the problem was discovered, it was easy to handle it next.

He checked twice and confirmed that there was only one trap, and then walked into the material warehouse to look for the materials needed for repairs.

Soon, he discovered the second fatal problem.

"This is not purple gold titanium, but... companion purple gold titanium!"

Zijin Titanium is a rare metal. It is a special alloy used to refine the spine of the magic wolf. It is an indispensable raw material and can greatly enhance the strength of the special alloy.

Associated Zijin Titanium is a very strange associated metal in Zijin Titanium.

Although the appearance, color and texture are almost the same as the real purple gold and titanium, there are some differences in properties, and it is impossible to increase the strength of the alloy at all.

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

"Is this another trap?"

"To test the eyesight of candidates, see if we can distinguish between purple gold titanium and associated purple gold titanium?"

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

Li Yao sat in the middle of the material warehouse, tapping his fingers lightly on the ground, thinking quietly.

In the monitoring room, the three chief examiners looked at one of the candidates who were grinning and thinking hard, and all showed weird smiles.

"You said, among the more than 300 candidates, how many of them can find the trap on the spine of the phantom wolf? Even if they find it, how long will it take to realize that we are providing the companion purple gold titanium, but'forgot' to provide it. 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.

One examinee made a call request.

"Excuse me, why is there no purple gold titanium necessary to repair the magic wolf in the material warehouse?"

In the light curtain, Jiang Shaoyang asked very calmly.
