Opu didn't expect that the gold coins brought by Zou Chuan were extraterrestrial products.

"These gold coins are minted by an underground organization that is trying to rebel against a frontier and is ......"

Zou Chuan only thought at this time that he had actually ignored a problem, but he immediately usurped a lie that was in line with the history of this planet.

The situation is very simple, while he travels around the world, he encounters an underground organization that is trying to establish a country and have a secret base of treasures, and he exterminates this organization and obtains this great wealth.

Oppe's eyes widened and he looked at Zou Chuan with a look of adoration, he did not have the slightest doubt about Zou Chuan's lies, because when Zou Chuan was on the prairie, he single-handedly killed a fierce evolved gray spotted shell insect with a dagger, and then killed more than 200 people for Ruth, and the time spent was extremely short, and what Zou Chuan said could become a reality.

"In order to cause some unnecessary hemp. Annoy, this coin must be melted before it can be put into use. ”

"Uh-huh, I understand, I understand!" Op nodded repeatedly.

……

Zou Chuan just told Op to build a pair. The armor piece didn't let Op start working immediately, because it was impossible for him to take out the corpse bird skeleton in the space button in front of Op.

Zou Chuan stayed and started in the city. Searching for some history books and researching the history of the planet, in the face of Zou Chuan's gold coins, Op left Zou Chuan without any hesitation, gave up his bedroom to Zou Chuan, slept in the hall by himself, and occasionally slept in Ruth's room.

Ruth spends most of her time in school, and Ruth encounters a huge . After the big blow, he became more and more well-behaved and mature, and every time he came back from school, he would help Op build a nail piece.

Op started his work the next day, which he never dreamed of. Zou Chuan would have more than a ton of corpse birds, and he had to clean up Ruth's room and pile up the dozen or so bags of bones.

Aopu always didn't understand how Zou Chuan put these east. Xi moved into the city, he wanted to ask several times, but every time he saw Zou Chuan's faint indifference, he retreated.

Actually, Op Present. It was difficult to see Zou Chuan, who stayed in his small room almost every day to read some purchased books.

It's been seven days, and except after buying books for the first time and eating for dinner, Zou Chuan has hardly left that room.

Zou Chuan has spent all his time studying the history of the continent.

When Zou Chuan saw the history of the eighteen countries, he was even more sure that this planet was transmitted from the earth.

History shows that the eighteen countries were actually one country more than eight hundred years ago, collectively known as the Gallon Empire, and through a series of wars, not many years after the founding of the country, it suddenly split up and became the eighteen countries.

There is no detailed explanation in the history books on how to divide the country, and the history of the founding and division seems to have been artificially tampered with and vaguely stated.

However, Zou Chuan still found some clues from a few words, and he speculated that it should be because of racial reasons, or because of the influence of the concept of a country on the earth, the humans on the spaceship had infighting, and established several single-colored races, among them, there were countries founded by whites, countries founded by blacks, and countries founded by Arabs, and the largest country was the yellow race of the Gallen Empire.

Obviously, on the adventure spaceship at that time, the number of yellow people occupied an absolute advantage, so the Gallon Empire was established mainly by the yellow race, and then, for various reasons, people of other races or countries began to separate from the Gallon Empire......

It is no wonder that the inspection of Zou Chuan was not strict when he entered the city, because Zou Chuan was yellow-skinned and black-haired, and he was a typical citizen of the Gallon Empire.

However, Zou Chuan has not found any clues as to why high-tech technology disappeared out of thin air, and judging from historical records, it seems that from the very beginning, human beings have been in a very primitive state, and they are not linked to high technology at all.

Of course, Zou Chuan still found some useful things, that is, more than 800 years ago, some handicrafts were very developed, and the only thing lacking was some high-tech products.

More than 800 years ago, there must have been a great change that deprived mankind of the basis for developing high technology.

You must know that a spaceship usually has a scientific research team on it, and the spaceship has almost all the advanced technology of the earth, as long as there is this scientific research team, with the support of the spaceship, it will soon be possible to establish a society comparable to human beings on a strange planet.

Unless, all the scientific research team on the spaceship died in an accident, however, this possibility is very small, after all, those fragile scientific and technological workers are impossible to leave the spaceship, and it is an extremely difficult thing for them to encounter danger together.

Could it be ......

Could it be that the interior of the spaceship has been attacked by some kind of force?

Zou Chuan raised his head and looked at the towering castle in the distance, his guess seemed to have no basis, because, the human race had multiplied on this planet, and the saucer-shaped spaceship was not damaged in the slightest, obviously, the human beings who landed on this planet at that time had a way to deal with the colorful shell insects.

It seems that the inexplicable disappearance of high-tech may only be solved by entering a saucer-shaped spaceship.

It's a pity!

Zou Chuan sighed and stood up, walked to the window, and looked at the soldiers patrolling the castle with spears and densely patrolling, if this planet had high-tech knowledge at the beginning, through the development of nearly a thousand years, it would inevitably develop a high degree of scientific and technological knowledge, and it was likely to surpass the human alliance.

In fact, in the great era of interstellar explosion of human beings, there are many human beings scattered in the depths of the universe whose scientific and technological level has surpassed the human alliance, and when these Ming return to the human alliance, the scientific and technological level of human beings will get a qualitative leap.

Zou Chuan is not very interested in the disappearance of Ke Ming now, he is more interested in how ancient humans defeated the colorful shell insects at the beginning?

What is certain is that the primary defeat of the Colorful Shell Worm by human beings is definitely not a high-tech weapon, because even the human alliance that has gone through thousands of years of development cannot completely defeat the Colorful Shell Worm under the use of high-tech weapons, let alone the ancient earth technology more than 800 years ago.

Martial arts!

It seems that the only explanation is martial arts, thinking of the weird body that Aopu, an ordinary civilian, has, Zou Chuan thought of martial arts.

After communicating the reason, Zou Chuan let out a long breath.

On the huge saucer-shaped spaceship at that time, there must have been a group of quite powerful martial arts masters, who defeated the colorful shellworms in order to protect the saucer-shaped spaceship, and even made the colorful shellworms begin to fear humans, just like mice are afraid of cats, so that when Op entered the prairie, the colorful shellworms did not take the initiative to attack.

In fact, although Op can shoot the colorful shell insects, but if you encounter a real wave of colorful shell insects, Aopu is actually very vulnerable, the key problem is that the fear of the colorful shell insects for humans has been rooted in their hearts, so they dare not take the initiative to attack humans.

Thinking of this, Zou Chuan couldn't help but admire the adaptability and wisdom of the Colorful Shellworm, when the Colorful Shellworm entered the Human Alliance, he immediately discovered that the humans of the Human Alliance and the humans of this planet were essentially different, so the fear of their brains disappeared, and humans became prey.

"Phew!"

Zou Chuan opened the door and walked out.

Op is working intensively, using a variety of tools to measure the bone fragments, polishing the arrows, from the specifications of the polished bone fragments, it shows that this is not a human armor, because, the size of the bone fragments is as large as possible, in fact, there is no need to polish so meticulously, the main thing is to formulate specifications.

Aopu is a little puzzled that most of the bone pieces are not connected to each other, except for some parts that require fine bone pieces, most of the bone pieces are not uniform, but they have corresponding specifications.

According to Zou Chuan's requirements, Aopu numbered each bone piece, and some bone pieces of different sizes would be numbered and stacked together.

Because there are not many places to polish these bone pieces, mainly cutting, Aopu's speed is still very fast, and now, Aopu has encountered a problem, he doesn't know how to make these bone pieces assemble together, but Zou Chuan doesn't have any requirements.

Working day and night, because there is no need for fine polishing, in seven days, Aopu actually sorted out more than a dozen bags of bones, most of which were cut according to Zou Chuan's specifications, and a small part was sorted out and packed.

The manufacture of arrows is only the beginning, and the pace is much slower.

During this time, Op has earned seven gold coins, basically one, seven gold coins is a huge wealth for Opple, perhaps, he will not be able to earn so many gold coins in his lifetime.

Aopu naturally didn't know that gold coins were the most useless metal on Zou Chuan's body, and in his space button, there were all kinds of rare metals stored, and gold coins were the most worthless, and they were the most, because gold coins have always been the hard currency of the Human Alliance, and they are common in most countries, Zou Chuan, as the supreme commander of the Hurricane Adventure Group, he also has to pay the members of the group, and the gold coins in his space button are calculated in tens of millions.

Zou Chuan didn't know the value of gold on this planet at all, in the Gallon Empire, the value of gold has far exceeded the value of gold itself, because this planet is a planet where metal is scarce, not to mention gold, even the most ordinary iron is quite scarce, which is actually one of the reasons why high technology cannot be developed......

"Brother Chuan, there are still three days before the time for conscription, I will try my best to complete the work here, it is estimated that it will be a little difficult......" Op looked at Zou Chuan with an apologetic face.

"It's okay, these arrows are not in a hurry......"

"Phew!"

"Phew!"

"Phew!"

……

Before Zou Chuan could finish his sentence, there was a sudden sharp knock on the door outside.

"Open the door, city defense rounds!" A gruff voice sounded outside the door.

"City defense rounds, it's over......"

Hearing the sound outside, Oppe's face suddenly turned pale, he looked at Zou Chuan at a loss, and glanced at baskets of arrows and boxes of bone fragments.
