After visiting the copper processing plant in Shu, Bass and Rag were confident that they could get enough metallic copper, but were a little worried about whether they could process the copper into a plate suitable for repairing the ship's hull. Because the technicians at the factory had a hard time making copper into sheets of uniform thickness, mainly because they had never done such a job. The technicians hope that any customer will be able to make the required copper plates in the factory by themselves, and the technicians will fully cooperate.

Bass understood that in addition to their lack of skill, these Shu technicians were afraid of the supplies needed to make the king's guests, because if anything went wrong and the guests were not satisfied, the king of Shu would never spare them.

However, both the bass and Rag were equally ignorant of how to handcraft the copper plates that met the minimum requirements for a ship's hull.

The two of them discussed with the princess for a while, and decided to report the situation in the factory to Raco, and asked him to check whether the Russ people had any handmade technology for copper products in the investigation report on the earth world, as long as they could find the relevant information, as an intelligent person with super learning ability, Rag could use the experience of others to develop the mold and processing method of copper plates in the factory.

Bass, who had neither the skills nor the interest in working in such a humble factory, volunteered to offer his two sapient companions that he would make preparations for Babylon with the princess, first to persuade the king of Shu and the priest to agree to the princess to go to Babylon with Daorong, and then to raise enough silk products to trade gold in the Western world.

After the work plan was set, the four of them left the factory, and after they returned to the palace, they asked to see the father and son of the king of Shu and the priest again.

In the course of this meeting, Bess not only made a deal to help Shu regain the lost border castle, but also talked about the great plan of strengthening the country and enriching the people to the king of Shu and the priest with the image of a knowledgeable and versatile wise man.

He said with a serious expression: "All the history of human civilization has a common characteristic, those strong nations and kingdoms that have lasted for thousands of years attach great importance to foreign trade, because trade with other kingdoms and regions can not only increase wealth, but also introduce products and technologies that are unique to other regions, and can also attract craftsmen and businessmen from other regions to work locally.

Therefore, we will go to the Western world to trade silk this time, and we will let the kingdoms of the Western world know that there is a silk-rich Shu country in the east, and Westerners will bring their gold and their good things to Shu to trade, and Shu will get huge benefits from it, and after the national strength becomes stronger, they can build more castles and control more land. From now on, I no longer have to worry about the rebellion of those surrounding tribes. ”

For the beautiful blueprint depicted by the bass, the king of Shu is very pleasantly surprised, he himself has dreamed of going to the legendary Western world since he was a child, but he has no choice but to travel far away and his kingdom is surrounded by dangers. What's more, the King of Shu knows his daughter's character very well, and no one can stop what she is going to do unswervingly, and the two supermen, Bass and Lager, can't be offended and must respond to their needs.

The old priest had long heard that the priests of the Western world had extraordinary skills and high authority, so he was also happy to let Daorong go to the Western world for a long time, and she would definitely be a high priest supported by the whole people when she returned to Shu in the future.

The eldest prince had seen that his sister and the young bass were attracted to each other, so he was happy to see it. The younger sister is arrogant, and only a god like Bass can match her.

A new deal was negotiated.

The next step is to prepare separately, the father and son of the King of Shu trained soldiers and horses to prepare to recapture the lost border pass, Lag entered the factory to command the Shu technicians to make copper plates, and the bass and Princess Yang and Daorong prepared silk products.

As soon as a new deal was negotiated, there was good news from Raco on the top of the mountain, and he consulted a lot of information, and finally found some technical information on the Sumerian smelting copper and making copper products from a long time ago from a long time ago, and he sent all the information to Rag.

Bass was relieved to learn that Raco had found the technical information for copper processing, and he believed that Rag would quickly work with the Shu technicians to make the required copper plates.

Rag worked hard, he stayed in the factory all day during the day with the technicians to improve the manufacturing process from the copper ore harvesting, returned to the ship with the bass at dusk, and while the bass slept, his two intelligent companions worked together on the problem of copper plate making, and once the new technology was developed, Rag was in the factory the next day to direct the technicians to put it into action.

。

After a few days of effective work, Raco and Shu technicians have improved every step of the manual operation process, from the smelting of copper to the making of molds to the polishing after final forming.

Finally, the first batch of copper plates of uniform thickness were made by them, and then Rag personally drove the flying car to send the copper plates back to the spaceship, and Raco was also satisfied after checking it, and the two intelligent people cooperated with each other to weld the copper plates.

At the same time, the army of the Shu State Army counterattacked the border pass and completed the training, and the father and son of the King of Shu completely recovered from their arrow wounds.

Bass and Princess Yang raised a batch of silk from all over the Shu Kingdom, and the silk had been dyed into several beautiful colors by plant dyes.

During this time, Bass spends most of the day alone with Yang, during which he unreservedly tells Yang about his true identity and experiences.

Although Yang felt incredible at first, after Bass's extremely patient explanation in simple terms, coupled with Yang's intelligence, she finally understood that there were countless magical worlds in the brilliant starry sky. Yang is fascinated by the Outer World described by Bass, and at the same time has great sympathy for Bass's homelessness, and their relationship quickly warms up.

On this day, Raco and Rag drove the repaired spaceship into the courtyard of the Shu King's Palace, and the Shu King's family and priests personally boarded the spaceship to check the magical treasures of the outer world.

According to the plan of action specified by Bass and others, the silk products and the personal belongings of the princess and Daorong were loaded into the spaceship in advance, and they would set off for the kingdom of Babylon after the Shu army captured the border castle.

Everything was ready, just waiting for the priest to choose the best time to go out.

On this day, when the sun was setting, the north wind that the priest was looking forward to was blowing, and the five thousand soldiers and horses of Shu left the capital and marched towards the southern border pass under the leadership of the prince and general.

According to the predetermined course of action, Bass, Princess and Dorong follow the prince's army to the front line in a carriage, while Rag and Raco wait in the spaceship, and once Bass arrives at the border castle, he will use the wireless signal of the intercom to guide his companion's ship to the exact coordinates of the front line.

The cavalry vanguard led by the prince himself took half an hour to reach a commanding height in the southern hills, where they could see with the naked eye the border castle five miles away, where they waited for the follow-up large army to arrive.

At the same time, Bass turns on the intercom to make contact with his companions in the ship, and Raco drives the ship to rendezvous with Bass in a few minutes under the guidance of the signal from the intercom.

After the spaceship lands on the ground, Bass, Princess, and Dorong board the ship.

When dusk fell, the infantry and logistics troops of the Shu army arrived, and the siege operation officially began.

The army of Shu did not attack immediately after approaching the city, but waited in line at the north gate of the castle.

In order to save the firepower of the ship's weapon system, Rag and Raco decided to use a scare plan to make the Uohara soldiers who occupied the castle abandon the castle and flee.

The spaceship flew up to the castle and hovered low in the night, while Rag shouted in a thunderous voice through the ship's call system: "I am the messenger of the gods, come to help the Shu people recapture the border pass, and make the defenders in the city immediately give up resistance and flee!"

Although the Uohara soldiers were shocked by the behemoth flying overhead, and had learned the power of the gods, no one dared to run away without understanding how this flying monster had left. At the same time, they also had luck in their hearts, and the things flying above their heads might just be scary phantoms made by the priests or supernatural beings of the Shu Kingdom.

Rag shouted for a while, seeing that the soldiers in the city showed no signs of fleeing, so he had to suggest that Raco blow up the north gate of the castle to allow the Shu army to force in.

Rako fired an accurate energy projectile at the north gate, which collapsed with the sound of an earth-shattering explosion. The Shu cavalry was the first to rush into the city, followed by a swarm of infantry.

The ship didn't leave there, still hovering over the castle, but the two sapients didn't want to waste firepower or kill humans indiscriminately, so they decided not to fire again until they had to.

The north gate exploded with a loud bang, letting the defenders know the power of the flying object overhead, so that they completely lost the fighting spirit to resist, and no matter how brave the soldiers were, they would understand that as long as the monsters in the sky existed, no matter how desperately they resisted, it would be a dead end in the end, so it was better to escape as soon as possible.

Therefore, the enemies scattered everywhere the Shu army went, and soon all the defenders of Yuyuan rushed to flee from the south gate.

When the Shu army completely occupied the castle, Raco drove the spaceship away from the battlefield and flew in a straight line in the direction of the setting sun.
