The unusual shape of the bronze gate made all Youfu soldiers look alert. Even the ancestor Youquan, one of the strongest men in the blood demon world, stared at the twisted relief.

The tombs and remains of ancient powerful people are the favorites of cultivators and demon clans. If one or two inheritances can be discovered, it can make the strength of people in the cultivation world have a qualitative leap, but there are often many mechanisms, and if you are not careful, you will lose your slaughter and sink your sand.

However, based on the research of many experts and the exploration over the past few days, it has basically proved that the closure of the Chaos God Tomb was because of an extremely tragic accident that caused everyone in the God Tomb tomb to be killed instantly.

Perhaps, it was because of the extremely powerful virus leak that many people became obsessed with, mutations, and killed each other.

In this case, Chaos's death was very hasty, and there were not enough followers to help him set up mechanisms after his death.

This is also one of the reasons why the ancestor Youquan dared to explore directly.

"Click! Click! Click!"

The sound of gears turning and the sound of iron chain friction under the bronze gate are getting closer and closer. At first, it seems to be coming from the ground, but at this moment it seems to be directly emitted from the ears and eyes of everyone. It makes people feel that what is being turned is not only the core of the bronze gate, but also its own internal organs.

Before the door was opened, some experts with weak physiques started to retching faintly.

"Crash!"

Immediately afterwards, the bronze gate suddenly sank.

"All fluorescent flying insects and searchlights are aimed at the bronze gate, and all Youfu soldiers retreat ten meters!"

The ancestor Youquan issued an order.

Dozens of searchlights seized and smuggled from the Tianyuan Realm, with crystal stones as the core and amplified by hundreds of light-concentrating talisman arrays, aimed at the bronze gate together. Hundreds of flying insects with crystal stones inlaid on their heads and buttocks also flew over the bronze gate.

The light they condensed and shone all around like day. Even so, just above the bronze gate, the light was still restricted, as if it was swallowed by the black fog surging out of the bronze gate.

Then the light compressed to the limit can be vaguely seen that the bronze gate sank four or five meters. First, it rotated three times to the left, and then two and a half times to the right. Then with a "clang", it seemed as if the center of the gate was opened, and the bronze gate split like a petal. It retracted back to the depths of the rock layer.

The bronze gate is laid on the ground, and the passage behind the gate penetrates vertically into the ground, like a vertical shaft, and you can't see the bottom when standing next to it.

"Centi-Pi, conduct reconnaissance!"

"Phantom Butterfly Demon Girl" said with a sharp voice.

A Youfu Army came out. He had very few human characteristics, more like a huge mixture of spiders and centipedes. There were two long limbs in front of his body, and there were more than a dozen red compound eyes densely covered with fluff at the end of his limbs.

The Youfu Army "cropped" and stretched its limbs to its limit.

His limbs seemed to have undergone special genetic modulation and were specially created for reconnaissance. The three-meter-long limbs were folded and all stretched out, reaching more than ten meters, connected from more than ten joints, and could freely turn in tortuous and complex channels.

The Youfu Army "cropped" will spread limbs covered with compound eyes and penetrate into the black and black cave.

The two commanders of the Youfu Army, Heiba ​​and Yuzuru, placed their hands near his "centi-legged" head, and connected them with his brain domain through synthetic neurons. They shared his vision.

"From the initial sound wave oscillation detection, this corridor is at least twenty kilometers long, and there are circles of threads on the cave wall to help people enter and exit, but the cave wall is extremely smooth, and ordinary people still cannot enter without tools."

"The corridor is covered with black fog. Even if the compound eyes of the 'centiped' have been specially modulated and practiced, they still cannot penetrate hundreds of meters."

"Hey, there seems to be a sound?"

At the end of the corridor, deep in the ground, a huge wave suddenly came from the roar, like a fountain suddenly surged from the ground!

"Be careful and be careful of abnormal movements!"

The fantasy butterfly demon girl "Verm" pulled back the "Cuba" and a ball of lightning rapidly expanded between the two giant halberd horns on the head of the mangul big bagua "Heiba".

Almost at the same moment, the rumbling tide surged up to the entrance of the cave, and a "boom" sounded like a volcano erupting, and a large ball of black gas rushed out!

"ah!"

The "Centipede" and the last amputation had not yet been pulled out of the shaft, but was hit by black gas, but it made a heart-wrenching roar. The compound eyes suddenly swelled like a deformed tumor. After a moment, the "Smacking" burst one by one!

A hundred-legged screamed heartbroken!

The "vortex" of the fantasy butterfly's wings shook slightly, and a colorful stream of light circled three times on the swollen limbs of "cropples". The broken limb fell in response to the sound, and it turned out like a poisonous snake that had chopped off the head. It jumped for more than a dozen times before turning into a pool of pus in the "hissing" sound!

The black air soared into the sky, covering most of the fluorescent flying insects. Half of the fluorescent flying insects' light was instantly extinguished, shriveled and withered, falling into the shaft like hail.

The other half of the fluorescent flying insect was a demonic light. It made a "hiss" sound from the mouth. The elys and limbs grew wildly, and even the wings became bigger, from the size of the original thumb to half the palm!

The fluorescent flying insects that became bigger were simply flares with wings, becoming extremely cruel, bloodthirsty, hungry, and thrilling, rushing towards the Youfu Army in all directions!

"The fluorescent flying insects are out of control!"

A Youfu Army exclaimed.

Most of the teams of the ancestor Youquan are Zergs, as the name suggests, they are experts in insect control techniques. Under their control, various insect monsters are like arm-to-arm fingers.

But now, this Youfu military used essence and blood to modulate it, like a fluorescent flying insect in his organs, and did not obey his orders!

At the critical moment, the "Heiba" of the Manniu Big Biaomeng shouted loudly, and the spherical lightning between the horns of the two halberds suddenly blasted out, exploded suddenly in the middle of the mutated fluorescent flying insects, turning into a giant power grid of more than ten meters in radius. The dark blue arc enveloped all the fluorescent flying insects!

"Sizi!"

Even though he was entangled by a strong electric arc, the fluorescent flying insects did not die in an instant. They still struggled violently, almost tearing the power grid several times and breaking through the siege!

"Um?"

The shells around Heiba ​​shook, and the demon pills embedded in his body suddenly shone, and the released arcs changed from dark blue to crimson red!

Under the turbulence of the crimson arc, most of the fluorescent flying insects were finally electrocuted into charred corpses, and they were wiped out with a "bang". However, there were still more than a dozen flying insects with particularly tenacious vitality. Not only were they not electrocuted, they further mutated in the arc, and spikes grew around them, and their mouthparts became three points bigger, like flashing caltrops!

"What?"

Heiba ​​seemed to have suffered a great humiliation. His face wrapped in black armor was steaming with wisps of blood. His arms were bombarded together like two crystal rail trains. The super demon pill like a heart-protecting mirror on his chest suddenly shone, and the electric arc that emerged from **** changed from crimson to white.

Finally, dozens of mutated mysterious flying insects were electrocuted!

"Spray stabilizer, fast!"

The "Whirlpool" of the Fantasy Butterfly Demon is both stern.

Several Youfu soldiers who were wrapped like rice dumplings came up.

They were wearing several layers of fully enclosed protective suits, and even anti-Gu poison suits from the Tianyuan Realm. They carried several huge silver high-pressure bottles, and the talisman arrays on the bottles were shining.

"Puff puff puff puff!"

A series of green foam emerged from the high-pressure bottle, forming a solid barrier around the black gas.

As soon as the black gas is stained with the green foam, the foam immediately seems to boil, wrapping the black gas and neutralizing it, producing a large amount of harmless light green gas that spreads in all directions.

"These black gas that accumulates in the deepest part of the Chaos Tomb seems to have the effect of stimulating cell activity in a crazy way. Once any creature is contaminated, it will consume its vitality in an instant and become extremely crazy!"

"Fortunately, this ancient black gas has a simple structure and can be neutralized by a stabilizer."

A Gu poison expert fiddled with several demon weapons from the Blood Demon Realm and air detection magic weapons from the Tianyuan Realm, and said quickly, "These black gas was closed in the depths of the Chaos Tomb for 40,000 years. During the 40,000 years, the crust was squeezed, and the external air pressure changed a lot, so it was sprayed out once the bronze door was opened. It was expected that it would dissipate in five minutes."

"However, there may be residual black gas in the deepest part of the Chaos Tomb. It is recommended to spray it with a stabilizer before exploring it."

Sure enough, after three minutes, the strength of the black gas gradually decreased, and the fountain that had exhausted the pressure slowly turned into a trickle. After five minutes, no black gas ejected out again.

Even so, the ancestor Youquan still asked the Youfu Army to wait for half an hour, and at the same time asked the experts to hang an air detection magic weapon into the depths of the shaft through the slender soft rope.

The length of the soft cable is ten kilometers, at least ten thousand meters deep, and no strong poisonous component was detected.

The air is naturally not suitable for ordinary people to breathe in the depths of the ancient tomb that has been closed for 40,000 years. However, the requirements for air among the demon race are not as high as that of humans, and they carry compressed oxygen cylinders, so there should be no problems.

Taking advantage of half an hour of dissipation, the Youfu Army carried out earthwork above the shaft and temporarily built a lifting platform with solid iron cables.

However, due to the limitation of the strength of the iron cable, the iron cable is only five thousand meters long. If it is longer, it will be broken by its own weight.

Many masters in the Youfu Army have the ability to fly and levitate. Even if they can't fly, they can still grab the cave wall like a gecko and dragon. This lifting platform is mainly for the transportation of supplies.

They were preparing to build a lifting platform every five thousand meters below the shaft, and through continuous relay, they could transport all the valuable things in the tomb. (To be continued.)
