In order to make a Terminator robot, it is first necessary to have a complete industrial chain and infrastructure, which means that Wangu needs to develop scientific and technological forces in this plane first.

This is not difficult for Wangu, because all kinds of scientific and technological information are available in Red Dragon mobile phones.

Even some low-tech technologies, such as generators, light bulbs, etc., can be refined by relying on their own refining techniques to "practice iron hands".

And as long as he has these most basic things, the Terminator robot carried by Wan Gu can develop his own technology and eventually create the Terminator robot.

However, in order to achieve the goal, with the current state of Bangu, the first thing needed is various mineral resources, such as iron ore, copper ore, silver ore and some rare metals.

But these things are not easy to get on the market, and there are a lot of them.

So Wangu basically has no other way than to find the mine by himself.

This is also why Wangu used the compass golden needle to find the target, and the compass golden needle that he manifested gave the golden needle the ability of super magnet with true yuan, which can detect the existence of iron ore.

A few people from Wangu flew all the way, and under the guidance of the golden needle, they flew all the way to the west for hundreds of miles, and sure enough, they came to a mine, and it was also a mine that had been mined.

However, unexpectedly, the mine still has the official logo printed on the outside of the mine, but it seems to have been abandoned, and the outside of the mine is overgrown with knee-high weeds.

"This is it." Wan Gu retrieved the compass golden needle and led everyone to the entrance of the mine.

"There's a demonic spirit!"

As soon as he landed, Wan Gu sniffed the tip of his nose and frowned.

"Demonic spirit?" Long Er hadn't learned the Dao method, so he couldn't detect the existence of demonic qi at all, and only felt that there was a faint smell of blood outside this mine.

It's actually not wrong to say that it's bloody, because there is a faint smell of blood here, but Wangu is more concerned about demonic energy, so he didn't say it.

Moreover, this demonic aura came from inside the mine, and the closer you got to the mine, the heavier the demonic aura became.

"Let me see what the hell is in there!"

After that, Wan Gu released his divine sense, carefully probed, and did not let go of a trace of clues.

Soon, Wangu's divine sense sensed a group of strange things.

It was a dense group of black spiders, countless weird green eyes, blinking in the cave, and in the corners of the cave, there were scattered dry bones.

In the middle of the spider colony, there was a black spider more than a foot tall, this giant spider had two dark green eyes revealing silky color, and a human face with green fangs, staring fiercely at himself at the entrance of the cave.

Its three-foot-long, chilling fangs protruded from its mouth covered in black fuzz, dripping with green, fishy venom dripping from it.

"It's a spider spirit!" The Divine Sense sensed the great spider, and at the same time, it also sensed the strength of this monster.

Its cultivation is at least the Martial Dao Yuan God Realm, but its strength is no longer as strong as the thousand-year-old tree demon of Lanruo Temple, because the gap between the demonic qi emitted by the two is too big.

If Wan Gu guessed correctly, it must be a spider spirit that has just broken through, because this spider spirit doesn't seem to even be able to transform yet, only turning into an ugly face.

"Who dares to trespass on my mountain gate!" The giant spider's divine consciousness also sensed the existence of Wan Gu and the others, revealing two fangs, roaring violently, and a rich demonic aura rushed to his face.

"It's horrible! Xianggong, what exactly is inside? Long Er shuddered and asked in shock.

"It seems to be a spider spirit who has just broken through to the Martial Dao Yuan God Realm! Long'er, do you want to use him to practice your hands? Wangu asked.

"Ah~, it seems to be much more powerful than me! I'm just in the Innate Qi Realm, can I really deal with it? Long Er muttered a little worriedly.

Although she is not afraid of spiders or anything, the gap between the cultivation of the two is indeed too big!

"Don't worry, if it's a ghost enemy, you really can't deal with it at the moment, but monsters are basically entities, and your martial arts plus my Xuanyuan Sword can still be dealt with." Besides, I will be there to protect you, and I will take action as soon as there is danger. Wan Gu said, took out the Xuanyuan sword, and handed it to Long'er.

If there is no Xuanyuan Sword, with Long'er's cultivation, it would be very lucky to be able to escape from the spider spirit of the Refining God Returning to the Void (Martial Dao Yuanshen) realm.

However, if you add the Xuanyuan Sword that slays demons and destroys demons, it will be a different matter.

Moreover, even if Long'er is defeated, a spider spirit who has just broken through to the Martial Dao Yuan God Realm wants to lower his eyelids and hurt Long'er in Wangu's eyes, which is tantamount to an idiot's dream.

"Okay!" Long Er hesitated for a moment, then took Wan Gu's Xuanyuan Sword. After all, she didn't want to be a vase either.

At the same time, the giant spider seemed to understand the contemptuous words of Kaguya and the others, its eyes showing anger, and its tail spat out a large viscous web towards the mouth of the cave.

The big web was easily flashed by Wangu and the others, sticking to the canopy not far away, and then the giant spider spirit pulled the spider silk on its tail, leading a group of small spider spirits to quickly follow the big web and pounce towards the dragon.

At this moment, Wan Gu, the three gods of the Bu clan and others all retreated to the high ground a hundred meters away, leaving Long Er alone standing at the entrance of the cave.

In the face of the giant spider's claw attack and the attack of the little minions, the dragon tapped under his feet, and the "Getaway" immediately came out, skillfully dodging the opponent's surprise attack.

The spider spirit roared, quickly turning around on the web, and unleashed a few slashes at the dragon.

The sharp air blade slash was mixed with mana, rolling in, and when Long Er saw this, the Xuanyuan sword came out of the sheath in an instant, and a sword flower easily slashed the air blade.

Facing the spider spirit of the Refining God Returning to the Void (Martial Dao Yuanshen) realm, Long Er didn't dare to be careless at all, nor did he dare to keep his hand, so he directly used his strongest move.

Holy Spirit Sword Technique - Sword Eighteen!

This move is the strongest style that Long Er has cultivated so far, because after that is the Ruthless Sword, it is not something that Long Er can touch.

When it was too late, Long Er instantly divided into dozens of phantoms, each of which seemed to be holding the Xuanyuan Sword, and then they all blasted out a Holy Spirit Sword Qi at the spider spirit on the big web!

Dozens of sword qi came out in an instant, with the momentum of thunder and thunder.

These dozens of sword qi mixed with golden divine light surrounded the spider spirit layer by layer, making it impossible to retreat.

Burst!

These dozens of sword qi with divine power slashed at the spider spirit at the same time, drawing deep and long scars, spraying out a long string of blood.

One move, just one move, with the help of the power of the Xuanyuan Sword, Long Er easily injured the spider spirit of the Refining God Returning to the Void (Martial Dao Yuanshen) realm.
