According to Han Xiao's speculation, this time the high-level leaders of the Spirit Sword Sect were in such a hurry......

Therefore, it is normal for fish to slip through the net...... In other words, the probability of monsters appearing in this hall is very high.

This hall is big enough, high enough, wide enough, but ...... It's just that there is less defensive formation, so to speak, if a monster appears, there is no danger to defend.

This one still hurts.

Therefore, Han Xiao decided to let the Spirit Rune Hall come here tomorrow to set up a warning talisman array. Nothing happened, he just sat here and drew a robot, ah no, it's going to be called a puppet here, and drew a design of a puppet.

This puppet was incorporated into some of the ideas of the Mechanism Technique by Han Xiao, and it was much better than the puppet after the Refining Hall.

Also, his energy is not made of spirit stones-spirit stones, which are rare in this small world.

After completing the design drawings, Han Xiao was thinking about how to get the resources to complete his space castle. He went to the warehouse, how many materials were left in the Spirit Sword Sect, and now, Han Xiao knew everything about it.

He made a rough estimate that even if he used up those materials, he wouldn't be able to complete his spatial castle.

The resources of this small world are really too few and too few.

The next day, Fang Yan, who had received Han Xiao's transmission note, brought the people from the Spirit Rune Hall here, arranged a warning talisman array, and then, with Han Xiao flew all the way to the Refining Hall, he began the refining of the puppet.

They say they are puppets, but in fact, they don't use spirit stones, but electricity!

In fact, the upper echelons of the Spirit Sword Sect also thought about replacing manpower with puppets so that the outer disciples could be freed from chores. However, the spirit stone became an obstacle.

There are simply not so many spirit stones in this small world to use as energy for puppets......

However, Han Xiao thought about it, the spirit stone was not good, he could use electricity as an energy source.

After arriving at the Refining Hall, Han Xiao first asked people to study the drawings, and then asked him if there was anything he didn't understand. As for him, he went to collect all the magic-level materials in the sect's inventory, and then returned to the refining hall.

At that time, the people of the Refining Hall had almost studied it, but there were many things that they didn't know too well.

Han Xiao waved his hand and said that when it was done, he would naturally understand.

Under Han Xiao's auspices, the disciples of the Refining Hall started work with wide eyes......

Why are they staring at each other with big eyes, because Han Xiao asked them to use "broken copper and iron" as puppets.

That's right, these steel, iron, and copper were purchased by Han Xiao from the secular world, and it is enough to use them as puppets.

As for the magic weapon-level materials for these puppets, Han Xiao was in his pocket with peace of mind—of course, at the moment, no one knew.

Han Xiao didn't think so, he was filling his pockets, this was replaced by him with alternative materials, and it was normal for him to use it.

And Tang Jian, who is in the secular Han family, has now become the person in charge of Han Xiao's acquisition of metal materials in the secular world. Otherwise, there are not many Fan Iron and Fan Steel of the Spirit Sword Sect, not enough for Han Xiao to control.

While the puppet was doing it, Han Xiao asked the generator that had started construction on the other side to start work......

When the strange puppet and the strange generator were made, the disciples of the Refining Hall said that they looked down on this kind of puppet.

Han Xiao set up the control program, ordered people to generate electricity, charge, and then taught those outer disciples to control these puppets to work.

For example, the hard work of mining ore can be done by them.

After doing this, and leaving the method of use, Han Xiao left the Refining Hall, and with the materials, he went to expand his Spatial Cave Mansion.

The disciples of the Spirit Sword Sect were stunned to see the puppets made of mortal iron and steel, using energy like thunder and lightning spells, stored in containers one after another......

They can work with something made of such low-grade materials, and they are also drunk......

Low-grade materials, plus low-grade energy, plus the method of making energy seems to be very low-level, which is to burn wood to make the generator generate electricity. Also, it is to use the water and wind power of the Spirit Sword Sect to generate electricity, then store it, and then charge the puppets......

However, these series of low-level combinations solved the problems that the high-level leaders of the Spirit Sword Sect had wanted to solve before but could not solve.

Of course, the puppet is not omnipotent, but it solves most of the problems.

The outer disciples of the Spirit Sword Sect can finally be freed from chores, and they can now practice freely as long as they can't do things for an hour every day.

Han Xiao really did not break his promise, and for three days, he personally led the outer disciples to practice martial arts.

In addition, the Spirit Sword Sect's Spirit Mine was now also a place that Han Xiao paid special attention to.

Although there are few resources in this small world, there are still some spirit mines in the spirit mine. Of course, in addition to a small amount of spirit stones and spirit ore, most of them are ordinary ores.

After Han Xiao learned more about it, he found that the spirit mines were all in those places where the spiritual energy was shrouded in the mountain gate of the Spirit Sword Sect.

In places where the aura can't be enveloped, there is not even a shadow of the spiritual mine.

This phenomenon caused Han Xiao to think deeply.

He studied the spiritual veins of the Spirit Sword Sect in detail, among them, the spiritual energy of the Spirit Sword Peak was the strongest, and then outside the huge mountain gate of the Spirit Sword Sect, the spiritual energy gradually thinned.

Digging deeper, Han Xiao unexpectedly discovered that in the huge sect of the Spirit Sword Sect, there was a faint formation to condense the spiritual energy and prevent the spiritual energy from spreading outward.

"Sure enough, the spiritual ore is slowly formed after years of changes in places with spiritual energy......

Spirit ore is the source of materials for all kinds of magic weapons and even magic weapons.

A good-grade spirit ore can refine magic-level materials, even if it is poor, it can also refine magic-level materials.

The scarcity of spiritual ore is the reason for the scarcity of materials.

This seems to be immutable.

Without materials, Han Xiao's space castle is difficult for a clever woman to cook without rice.

After thinking about it, Han Xiao had a bold idea: "Can you turn ordinary metal into magic materials......

This idea is a solution to the scarcity of materials, but it is easier said than done.

The birth of the spirit ore alone, even under the right conditions, has to go through many years of changes before it can be slowly formed.

Turning ordinary metal into magic weapons or even magic weapon materials by artificial methods has never been done before.

Those who dare to think like this are either crazy or stupid, and the remaining one is, of course, a genius who looks very much like a madman.

Han Xiao also knew that this was not an easy task, but after all, this was an idea that could solve the problem of material scarcity. He can experiment slowly, even if it doesn't work, it doesn't matter, just as a personal interest and curiosity.
