Opp never expected that the gold coins brought by Zou Zichuan were extraterrestrial products.

"These gold coins were minted by an underground organization that was attempted to rebel on the frontier...."

Only then did Zou Zichuan realize that he had overlooked a problem, but he immediately usurped a lie that conforms to the history of this planet.

The situation was very simple. When he was traveling to various countries, he encountered an underground organization. This underground organization tried to establish a country and possess a treasure secret base. He wiped out the organization and obtained this huge amount of wealth.

Opp opened his eyes wide and looked at Zou Zichuan with admiration. He had no doubt about Zou Zichuan's lies, because when Zou Zichuan was on the prairie, he killed a fiercely evolved gray shellworm with a dagger, and then killed more than 200 people for Ruth. Moreover, the time spent very short, what Zou Zichuan said could have become a reality.

"In order to cause some unnecessary trouble, the gold coin must be melted before it is practical."

"Yeah, I understand, I understand!" Opp nodded repeatedly.

...

Zou Zichuan just told Opp to create a pair of armor pieces, and did not let Opp start working immediately, because it was impossible for him to take out the corpse and bird bones inside the space button in front of Opp.

Zou Zichuan stayed and began to search for some history books in the city to study the history of the planet. Facing Zou Zichuan's gold coins, Opp left Zou Zichuan without any hesitation, gave up his bedroom to Zou Zichuan, slept in the hall, and occasionally slept in Ruth's room.

Ruth spent most of her time in school. After Ruth suffered a huge blow, she became more and more obedient and mature. Every time she came back from school, she would help Opp create aphrodisiacs.

Opp started his work the next day. He never dreamed that Zou Zichuan would have more than a ton of corpse skeletons of corpse birds. He had to clean up Ruth's room and pile up all of them with more than a dozen bags of corpse bones.

Opp always had a little bit of understanding how Zou Zichuan moved these things into the city. He had asked several times, but whenever he saw Zou Zichuan's faint indifference, he retreated.

In fact, it is difficult for Opp to see Zou Zichuan now. Zou Zichuan stays in his small room almost every day and reads some purchased books.

It has been seven days since I bought the books for the first time, and Zou Zichuan almost never left that room during dinner.

Zou Zichuan spent all his time studying the historical research of this continent.

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

History shows that the eighteen countries were actually one country more than 800 years ago, collectively known as the Gallon Empire. Through a series of wars, it suddenly split and became eighteen countries not many years after its founding.

There is no detailed explanation of how to split in history books. The history of founding and splitting seems to have been artificially tampered with, and it is very vague.

However, Zou Zichuan found some clues from his words. He speculated that it should be because of race, or because of the influence of the concept of state on the earth, that humans on the spacecraft had internal conflicts and established several races with a single skin color, including countries established by white people, countries established by black people, countries established by Arabs, and the largest country was the yellow people of the Gallon Empire.

It is obvious that in the adventure spacecraft at that time, the number of yellow people had an absolute advantage, so the Gallon Empire was established mainly by yellow people. After that, for various reasons, people from other races or countries began to separate from the Gallon Empire...

No wonder the inspection of Zou Zichuan was not strict when entering the city, because Zou Zichuan had yellow skin and dark hair, and was a typical citizen of the Gallon Empire.

However, Zou Zichuan still found no clues about why high-tech technology disappeared out of thin air. Judging from historical records, it seems that from the very beginning, human beings have been in a very primitive state and are not linked to high-tech at all.

Of course, Zou Zichuan still discovered some useful things, that is, more than 800 years ago, some handicrafts were very developed, and the only thing they lacked were some high-tech products.

More than 800 years ago, a huge change must have caused mankind to lose the foundation for developing high-tech.

You should know that there is usually a scientific research team on a spacecraft, and the spacecraft has almost all the advanced technology of the earth. As long as there is this scientific research team, with the support of the spacecraft, a society comparable to humans can be established on a strange planet.

Unless all the scientific research teams on the spacecraft die in an accident, the possibility is slim. After all, it is impossible for those scientific and technological workers with fragile bodies to leave the spacecraft. It is an extremely difficult thing to let them encounter danger together.

Could it be...

Could it be that the spacecraft has been attacked by a certain force?

Zou Zichuan raised his head and looked down on the towering castle in the distance. His guess seemed to be based on no basis, because humans had reproduced on this planet, and the disc-shaped spacecraft was not broken at all. Obviously, the humans who landed on this planet at that time had the way to deal with colorful shell insects.

It seems that the inexplicable disappearance of high technology may only be able to enter the disc-shaped spacecraft to solve the mystery.

What a pity!

Zou Zichuan sighed and stood up, walked to the window, and looked at the soldiers who were patrolling closely on the castle. If this planet had a high-tech civilization at the beginning, through the development of nearly a thousand years, it would inevitably develop a high level of technological civilization, which might be more likely to surpass the human alliance.

In fact, in the era of interstellar explosion of human beings, many human civilizations scattered in the depths of the universe have surpassed the human alliance. When these civilizations return to the human alliance, human technological level will make a qualitative leap.

Zou Zichuan is not very interested in the disappearance of technological civilization now. What he is more interested in is how ancient humans defeated the colorful shell insects at the beginning?

What is certain is that humans are definitely not high-tech weapons to defeat colorful shellworms at the primary stage, because even the human alliance that has been developing for thousands of years cannot completely defeat colorful shellworms by using high-tech weapons, not to mention the ancient earth technology more than 800 years ago.

Martial arts!

It seems that the only explanation is martial arts. Thinking of the strange body skills that ordinary civilians, Oup, had, Zou Zichuan thought of martial arts.

After the reasons were communicated, Zou Zichuan let out a long sigh.

At that time, there must be a group of very powerful martial arts masters on the huge disc spaceship. In order to protect the disc spaceship, they defeated the colorful shellworms, and even made the colorful shellworms begin to fear humans, just like mice fear cats, so that when Opp entered the prairie, the colorful shellworms did not take the initiative to attack.

In fact, although Opp can shoot and kill colorful shell bugs, if you encounter a real colorful shell bug tide, Opp is actually very fragile. The key problem is that the colorful shell bugs have already become rooted in their hearts, so they dare not take the initiative to attack humans.

Thinking of this, Zou Zichuan couldn't help but admire the adaptability and wisdom of the colorful shellworms. When the colorful shellworms entered the Human Alliance, they immediately discovered that there was an essential difference between the humans in the Human Alliance and the humans on this planet. Therefore, the fear in their brains disappeared and humans became prey.

"Bang!"

Zou Zichuan opened the door and walked out.

Opp is working very hard, using various tools to measure bone pieces and polishing arrows. From the specifications of the polished bone pieces, it shows that this is not a human armor, because the specifications of the bone pieces are as large as possible, and in fact, there is no need to be polished as carefully, and it mainly sets the specifications.

Opp was a little confused. Most of the bone pieces were not connected to each other. Except for some parts that required fine bone pieces, most of the bone pieces were not uniform in specifications, but had corresponding specifications.

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

Because there are not many places to polish these bone pieces, mainly cutting, Opp is still very fast. Now Opp has encountered a problem. He doesn't know how to assemble these bone pieces together, but Zou Zichuan has no requirements.

Working day and night, because there is no need to polish, in seven days, Opp actually sorted out more than a dozen bags of bones, most of which were cut according to Zou Zichuan's specifications, and a small number were sorted and packed.

The manufacturing of arrows is just the beginning, and the speed is much slower.

During this period, Opp has earned seven gold coins, basically one. Seven gold coins are a huge wealth for Opp. Perhaps he will never be able to earn such gold coins in his life.

Oup naturally didn't know that gold coins were the most useless metal on Zou Zichuan. In his space button, there were various rare metals stored, among which gold coins were the most valuable and the most, because gold coins have always been the hard currency of the Human Alliance and were used in most countries. As the highest commander of the Hurricane Adventure Group, Zou Zichuan also had to pay food and salary to the members. The gold coins in his space button were calculated in tens of millions.

Zou Zichuan didn't know the value of gold on this planet. In the Galen Empire, the value of gold has far surpassed the value of gold itself, because this planet is a planet with scarce metals. Not to mention gold, even the most ordinary iron is quite rare. This is actually one of the reasons why high technology cannot develop...

"Brother Zichuan, it's time to recruit troops in three days. I will try my best to complete the work here. It's probably a bit difficult..." Opp looked at Zou Zichuan apologetically and said.

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

"Bang!"

"Bang!"

"Bang!"

...

Before Zou Zichuan could finish a sentence, a sharp knock on the door suddenly came from outside.

"Open the door, the city defense inspection room!" A rough voice sounded outside the door.

"The city defense inspection round is over..."

Hearing the sound outside, Opp's face turned pale, he looked at Zou Zichuan at a loss, and gave another glance at the baskets of arrows and boxes of bone pieces.
