At the same time as Zhang Chujiu made his move, on the hills around the monster, several 'armed creations' made of alloys suddenly appeared.

The height of those all-metal killing tools is about 3 meters, and the torso is overlapped by 4 layers, and each layer is equipped with 4 large-caliber gun barrels that can move up and down freely in four directions: east, south, west, and north.

Eight octopus-like tentacles extend from the base of the turret, and at the bottom are limb legs that closely resemble spider feet.

The soft metal tentacles that lurked wrapped around the base of the turret, and the limbs and feet shrank into the base.

During the battle, the alloy limbs stand upright, and the four layers of turrets are fired at the same time, which can carry out high-intensity fire strikes with a range of 360 degrees.

Even if an enemy is outnumbered or lucky enough to break into the corner of the long-range firepower, it will be cut and smashed by the sharp limbs and feet like a war knife or the tentacles as heavy as a steel whip.

Although the number of underground monsters was overwhelmingly dominant, Zhang Chujiu cooperated with the fierce offensive of those armed creations, and he still quickly formed a suppression.

According to the explanation of the Mixed Yuan Cave, the cave where the mountain gate is located is one of the passages leading directly to the 18th layer of hell in the world.

In ancient times, when hell really existed, it was not the ghosts of the living who turned into ghosts after death, but the 'ghost race' that competed with the human race for thousands of years, leaving countless terrifying marks that have not completely dissipated to this day, and finally evolved into the 'ghost race' of hell, purgatory, abyss, and other legends.

According to the ancient texts handed down from the Mixed Yuan Cave, the ghost clan is not like viviparous humans who have a father and a mother, but are born and raised by the extreme yin qi of the earth.

At the beginning of birth, there is a clear distinction between strong and weak, the strong do not need to cultivate, and as they get older, their strength will skyrocket, and the weak cannot become too strong no matter how hard they cultivate.

Because of this characteristic, a 'Mandate of Heaven' gradually arose among the ghost race, and the entire civilization was no longer progressive, and finally it was completely defeated by the human race thousands or tens of thousands of years ago, and then the entire extinction.

After that, the great powers of the human race worked together to exert their magical powers, causing the magma in the center of the earth to gush hundreds of zhang, creating countless volcanoes in various parts of the Blue Star, disturbing the underground Yin Current, blocking the possibility of large-scale breeding of the ghost race, and completely eradicating the root cause of the enemy's strengthening.

Since then, except for those ghouls in hell who don't know whether they are lucky or unlucky, their memories and sanity are completely lost after death, and their strength is reduced by half every time they come back from the dead, and they only rely on the instinct of killing, the number of newly born ghosts is more than one compared to before.

And those ghost races with strong natural potential are almost no longer born, and the ghost civilization has been completely destroyed, even if the new ghost race has wisdom, there is no chance to gain knowledge, and can only live like beasts, completely losing the possibility of threatening the rule of human beings on the earth, and gradually being forgotten underground.

These legends are now no longer true and false, and the only thing that can be determined is that the so-called hell has become the back garden of the people of the Mixed Yuan Cave Gate to 'make money'.

It was a disciple like Zhang Chujiu who joined the sect half-heartedly, and he also infiltrated it, and worked tirelessly to strangle the ghouls and ghost clans, just to obtain the various legacies left by the ancient ghost civilization;

When the ghost race was first exterminated, in order to monitor this great enemy of mankind and prevent it from resurrecting, the relics left by those ancient cultivators who stayed in Hell to cultivate;

and the relics left by the medieval cultivators who were attracted by the heritage of the ghost clan and rushed to 'make gold' before the Mixed Yuan Cave was not opened and the hell was not completely forgotten by the human race.

Even with the upper hand, it took him a full 30 minutes to completely destroy the enemy this time.

After the victory, Zhang Chujiu drove the mechanical armed creatures to temporarily act as migrant workers, using metal tentacles to continuously pick up the remaining ghost armor and weapons around them and pile them under the boulders.

If this pile of ancient alloy tattes is sent to the "Reward Palace" of the Mixed Yuan Cave, it can be exchanged for tens of thousands of blue coins or 10 contribution points, but it has other value for Zhang Chujiu.

Since he started brainstorming by researching the design of the Nalotte battleship and continued to explore the potential of cranial nerve mutations, he has made great progress in the ancient Chinese Momen weapon making technique and the modern interstellar civilization mechanical weapon manufacturing.

After being promoted to the point where you can make it with the 'Sansheng Ding', which is equivalent to your own evolution to the peak of the 5th level of extraordinary life combat power, I have always wanted to practice it.

It's just that when Zhang Chujiu reached the peak of the fifth level of transcendent life, the peak of attack and defense had reached 3,600 intensity, and the power of making an armed creation with similar power was impossible, even if he was skilled and did not need to use special materials such as fantasy raw materials, it was impossible to continue to use cheap alloys to deal with things.

Zhang Chujiu calculated, if he wants to implement his idea, the cost alone will need more than 10 million blue yuan, in addition to the cost of ammunition consumption, energy consumption, damage repair and other aspects to consider.

Although in terms of combat capability and cost comparison, such a value is more than the entire interstellar civilization, any military factory will accept.

But he still felt that the cost was too high, and he didn't make it until that day, when he was brought by Song She to dive into the depths of the cave and get a lot of metal remnants left by the ghost civilization as trophies, he changed his mind.

According to Song She's idea, these remnants should be dedicated to the master as Zhang Chujiu's first meager contribution point income.

But Zhang Chujiu is not only a transcendent person, but also a genius in the creation of weapons, how could he not see the hunting heart when he saw the ancient alien alloy, so he hid part of the harvest and hid it in the Sansheng Ding.

The alloy formula used in the ghost man-made device has long been lost, but Zhang Chujiu's Sanshengding can easily break it down into a single metal element.

As a result, he discovered that one of these elements, a mysterious metal that he had never seen before and unknown, could be transformed into a miraculous increase in the conductivity and toughness of the alloy as long as it was fused with a very small amount of ordinary metal as an additive.

This time, Zhang Chujiu became interested and named this metal element 'Ghost Gold X'.

After several days of research, a series of new alloys were created using the ghost gold x, which can be decomposed in almost all metal items left by the ghost clan.

And using these alloys as raw materials, we successfully manufactured a weapon with a peak intensity of 3600 in attack and defense at a cost of less than 1/10.

The 'Spider and Octopus Turret' used in this eradication of ghost corpses and newborn ghost clans is one of the best comprehensive performance.

It was with the strength of this self-propelled fort that Zhang Chujiu began to sneak into hell alone and collect the metal left over by the ghost clan.

After the war, all the loot was packed into the Sansheng Ding, and after decomposing, it was calculated that the accumulated ghost gold x was enough to make thousands of tons of new alloys, Zhang Chujiu showed a satisfied smile, rested for a while, blessed the two evil powers, and flew straight towards the direction where the Mixed Yuan Giant Grotto was located.
