two,

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

The elevator is like a huge metal disc, relying on the anti-gravity talisman array to slide silently in the darkness.

The balance talisman array at the edge of the disc emits a faint blue light, reflecting the extremely tired faces.

For more than ten hours, the brain was running at an ultra-high speed. Even if the candidates were powerful cultivators, they could not bear it.

The candidates were clearly divided into two groups.

340 candidates sat outside the large disc to form a large ring.

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

Li Yao and Jiang Shaoyang.

The crazy performance of the two monsters at the level of the two shocked everyone. Everyone couldn't help but stay away from them, for fear of disturbing the showdown between the two monsters.

Just like in the prehistoric world billions of years ago, two Tyrannosaurus Rex were confronting each other, and there would be no creature dared to stand among them.

At a moment, everyone's eyes were blurred.

The elevator finally broke through the darkness and sank into the ground a thousand meters below.

The majestic scene in front of you made everyone's breathing stagnate.

They are in an extremely huge underground cave.

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

Looking down, it was still a black piece of dust and there was no bottom at all.

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

The honeycomb is like a huge steel honeycomb inside.

And they are just the tiniest ants.

Even the giant elevator, after sinking into the cave, turned into a lonely boat, with countless slightly luminous metal discs flying around, showing a busy scene.

"This is the power of the country!"

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

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

Li Yao sighed in his heart that while he felt his insignificance, he also felt deeply proud of being a member of such a powerful country.

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

Two firefly-like spots of light floated up from the underground abyss and flew to the disc.

But there were two soldiers with metal wings stuck behind them.

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

"Didi!"

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

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

The big disc rose and fell. Everyone was sent to the corresponding cave according to the test number.

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

The last level is here!

Li Yao looked at the cave curiously. He was very familiar with the furnishings around him. This was a repair workshop, and there was also a small refining room and a material warehouse behind him. Although the sparrow was small, it was all-in-one.

"Didi!"

The Exam Jingnao sent a message, the question in the actual test session was to use the facilities and raw materials in the repair workshop to repair a puppet war beast within 24 hours to restore it to at least 90% of its combat effectiveness.

“Repair type task?”

Li Yao was happy. Didn’t he just hit his gun?

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

"Phantom Wolf?"

The puppet war beast, similar to the "wooden ox and flowing horse" that Li Yao repaired in a small mountain village a year ago, is an artificial spiritual weapon that is controlled by a crystal brain and has a certain ability to act independently.

Fantasy Wolf is a puppet war beast refined by the Wolf Valley thirty-three years ago.

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

This puppet war beast uses the principles of bionics and refers to the appearance characteristics of many wolf and leopard monsters in its design. It is narrow and long, streamlined, quick in movements, and has a very fast speed. It is suitable for various complex terrains. It is especially suitable for fighting in grasslands and jungles. Even on steep mountain rocks, it can climb freely.

The fantasy wolf is a light war beast with a length of 146 meters and a total weight of 15,633 kilograms. It is equipped with a light crystal magnetic cannon on both sides of the body. A flying sword launch system can be added to the abdomen, carrying twelve miniature flying swords, greatly enhancing long-range firepower.

In addition, four shock claws were created with super alloy at the ends of its front and rear limbs. The biting force of the steel teeth was extremely strong. There was also a flamethrower in his throat. Driven by the flame talisman array, it could shoot out more than one thousand degrees of flame flow, instantly turning the enemy into gray.

There are two combat modes of Fantasy Wolf.

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

You can also enter rough targets in advance, such as "patrol", "guard", and "free hunting", and then control it by the built-in crystal brain of the Phantom Wolf to fight on its own.

As soon as the fantasy wolf appeared, it immediately replaced many military dog ​​spirit beasts and became the favorite of the military, especially the scouts.

To this day, a standard reconnaissance squad of the military is composed of two scouts and a phantom wolf.

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

It seemed that it ate the monster at a distance and attacked with acid. The metal body was corroded and was full of holes, and many crystal lines connecting the key points were corroded and broken.

Then he started a hand-to-hand fight with the ferocious monster. One side of his head was deeply sunk, his body was torn into pieces, and three of them broke in the four legs, and between the two front legs and the body, there were only a few pitiful crystal lines still connected.

A shocking hole was taken out of the abdomen, and many chips and organs engraved with key talisman arrays were gone, and the rest were mottled by the acid liquid and could not function properly.

Apart from the fact that a special alloy-refined spine is still intact, the phantom wolf is almost on the verge of being scrapped.

For Li Yao, this is a common scene.

Whether in the magic weapon grave or in the ruins of the Dahuang War Court weapon refining system, 90% of the magic weapon is on the verge of scrapping, or even completely scrapped.

So what?

He has repaired it bit by bit, even more powerful than before.

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

Li Yao rubbed his hands, focused on his intense repair work.

The first step is to disassemble all the components of Huanlang, see which components can be retained, which must be repaired, and which do not even have the value of repair, so they can only be refinished.

“Huh?”

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

In his hand was the intact vertebrae of the Phantom Wolf.

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

He did not hesitate. He folded his fingers and flicked gently towards the 22nd spine. He listened carefully to the sound of metal shock, and outlined a complex sectional view in his brain.

"There is a problem with the 22nd vertebrae!"

"Although the appearance looks intact, it has been hit several times with strong impacts. The inside is already covered with subtle gaps that cannot be recognized by the naked eye, reaching the limit of metal fatigue!"

"Just have another high-speed impact. No, no need to impact. As long as this phantom wolf performs another emergency stop and change direction during super-high-speed movement, the bone will completely explode!"

There is a saying that a wolf has a copper head, iron tail, tofu waist, and the waist is a fatal weakness.

The same is true for puppet war beasts like Fantasy Wolf. In order to pursue speed and flexibility, the body is streamlined. The waist connecting the front and back of the body is also the most fragile part, and it is almost supported by the spine.

Moreover, unlike wolf-like monsters, there are crystal magnet cannons on both sides of the body of the Phantom Wolf. The recoil force when firing will also bring huge pressure to the waist.

The 22nd spine, just right at the waist, is the key to the key. Once it bursts, it is equivalent to paralysis of the lower body and instantly losing 95% of its combat power!

"It seems that this is a trap."

"At first glance, this phantom wolf is full of holes, broken, and covered in bruises...but these are all small problems."

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

"If you only care about repairing the injuries on the surface and ignore the hidden injuries on the spine, even if you look completely new, you will not be able to withstand the actual test. When you arrive on the test field, you will do a few high-speed maneuvers and your waist will be broken!"

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

He checked it twice and confirmed that there was only one trap. Then he walked into the material warehouse to find the materials needed for repair.

Soon, he discovered a second fatal problem.

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

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

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

Although the appearance, color, texture is almost the same as that of real purple gold titanium, there are some differences in properties, which cannot improve the strength of the alloy at all.
