With the acquisition of the copper coin, something seemed to disappear in the body, Pan An thought carefully, and was able to recall that he had sold three hundred anime, but he couldn't remember which anime exactly.

Pan An quickly put his mind on the original heart guard, and communicated with the heart guard in terms of soul.

No matter how much mental power is mobilized, the brain always lacks that memory.

Pan An kept his eyes on the notes on the side and quickly opened the notebook.

"Insect Master"

"The King of Campus Confusion"

Final Exile

Abandoned Princess

"Daily"

"Little Fat Family"

Digimon

After the Decline of Humanity

"Blue Lan Island Drift"

Horizon of Record

"Strawberry 100%"

"Guardian Cat Lady Scarlet Bow"

......

The names of the three hundred anime and the impressions after watching them were quickly recorded in Pan An's mind, but these are newly acquired memories now, not memories that are recalled.

Pan An roughly remembered the lost memories, and then looked at the original heart guard.

"Oba!"

The Guardian of the First Heart let out a meaningless strange scream, and then pointed the mirror in his hand directly at Pan An.

Traced back!

At the same time that Pan An was recorded in the mirror, the book in the other hand of the original heart guard also floated automatically, quickly recording Pan An's previous life trajectory.

Pan An looked at the mirror, and the original guardian looked at the book, and the memories of the two perspectives were going on at the same time.

Soon, Pan An watched all the actions in the past twenty minutes, but he couldn't find the lost memories......

"Is there really no way...... Pan An sighed, but then his eyes became firm, "Since even the soul can't preserve those relevant memories, it means that I'm not strong enough now, not strong enough to break the rules!"

In Pan An's plan, the test point for selling this memory is not only whether the soul can keep the sold memory, there are still many places to verify!

One defeat did not affect Pan An's will and confidence, and Pan An focused on the sale column in front of him.

[Hand of Steel] is the knowledge of the Lord of Steel, a craft ability that is common in the Iron Empire, even low-level robots. This is a small part of the physical rules of the world you are currently in, and with it, you will gain memories of the Steel Hand, including the composition of materials and the principles of construction.

Purchase price: 50,000 copper, the lowest price, the mechanical dog that was originally used as an invitation reward has been canceled.

"Finally there is good news. Pan An felt much smoother, this Lord of Steel and the previous Overlord of Nagasaka Mountain were not the same personality at all, and they had to get along better.

In the past, Pan An also guessed who the Lord of Steel was who was, and even suspected that the other party was a person who used steel, or a strong man like Iron Man.

But judging from the current information, the Lord of Steel is not the master who uses steel, but the head of the Empire of Steel!

Unlike the loner Nagasaka Mountain overlord, this is an organized powerhouse!

Being organized means that there are rules, whether it is good or bad, it is all profit-seeking, Pan An's most troublesome thing is the chaotic thing like Aoyama Ginji, the other party can do things that do not conform to the rules when he is in a good mood or when he is not good.

Just like Pan An hates Aoyama Ginji, Aoyama Ginji also hates Pan An who has a helpless and dull expression all day long.

The existence of the Lord of Steel gave Pan An more confidence in the powerhouses of the other world.

"The ...... of the Steel Hand" Pan An made a decision after taking a look.

At present, there are more than 50,000 copper coins in my hand, and if I buy this thing, I will be close to bankruptcy.

"Buy!"

Without hesitation, Pan An was not sure if anyone else would be able to see the sale, in case he met the kind of person who deliberately caused trouble to others and spent money to buy this thing, then Pan An would ...... I have to fight that man to the death!

With the disappearance of the copper coin, Pan An also had an extra memory in his body.

This memory does not include people and scenes, but mere memories of materials and processes.

Soon, Pan An mastered a new technique, understood the composition of a synthetic material that had never been seen before, and also learned the process of making weapons called [Steel Hand].

The Hands of Steel is a general term for a class of weapons, which simply describes the replacement of human arms with machines made of steel.

Steel is a general term that refers to a hard metal, not steel as it is here on Earth.

The Iron Hand needed a metal that was soft and flexible, as well as extremely resistant to high temperatures and electricity, while also expanding and stretching.

The Steel Hand is equipped with these abilities, allowing it to condense dense air from the palm of its hand and strike it.

"Blame...... Isn't that more powerful with bullets?" Pan An couldn't help but have such doubts, frowning and thinking, "Isn't it more efficient to simply launch and compress the energy of the air when it is used to push solids?"

Is it because of the fear of exploding?

Pan An thought about the rules of physics he knew, and at the same time recalled some of the technological weapons he knew.

Technology such as electromagnetic cannons, although it is more troublesome according to modern technology, can indeed be made, but the power is much weaker than ordinary weapons, so there is no need to do it.

The air cannon also belongs to this kind, the power is too weak, and normal scientific research institutions just use it for fun, and they will not really look inside and invest it.

In a word, the technology tree is crooked.

In the eyes of the earthlings, their own technology tree is correct, and perhaps in the eyes of some people in other worlds, the earth's technology tree is a little crooked.

Pan An gave up this thinking, and now the focus is not on air cannons and palm thunder and arrows in the palm, who is more efficient.

Pan An's acquisition of the Steel Hand is the first step to gaining knowledge from the outside world, which is a small step for Pan An, and a big step!

"Hands of Steel......

Without thinking about why the Steel Hand was used as an air cannon instead of an air gun, Pan Ann quickly discovered a problem.

"I don't have the arms to control the Steel Hand...... I don't understand the wiring and the control of brain areas, I don't understand ......"

The Hand of Steel is obviously just a component, and Pan An can make the Hand of Steel, but he can't make anything more advanced than the [Hand of Steel].

It's just a small accessory, like a robot's arm, not the core chain of command.

But even this is very valuable, whether it is this new material, or the ability to compress and launch attacks in a small area, it can promote the progress of this world.

What Pan An wants most is a steel body that will never age, but now there is no way but to move forward little by little.

The Steel Hand, which uses an air cannon as an attack capability, seems to be foolishly ignoring the rules of physics and not being used to its fullest potential.

But just like firecrackers and bamboo bows, the former evolved into hot weapons such as cannons and missiles, and the latter developed into cold weapons such as crossbows and catapults.

If the air cannon is just the same starting point as firecrackers and bamboo bows, or an intermediate product of the evolution of gas weapons, then what technology will evolve from there?

"Try making a [Steel Hand] and see!"
