In the 8950th year of the Blue Star calendar,

after Xia Qingshan said that he wanted to return home in glory, Lin Jiang began to investigate the news of Xia Qingshan's hometown Lingyun Star.

Xia Qingshan knew a lot about the internal news of Lingyun Star, but in the interstellar space, those news were garbage and useless.

Xia Qingshan only knew that Lingyun Star was at least hundreds of light years away from Blue Star. He pointed out a direction before, but Lin Jiang thought it was unreliable and had to find it himself.

Lin Jiang launched a lot of detectors from Blue Star, all using the latest technology, that is, Lianglong's water drop robot technology, abandoning most of the functions, and can reach about one tenth of the speed of light.

In addition, Lin Jiang also refined many signal devices for the secret art of the star gate, and also learned the methods of Buddhism, disguising the signal devices as meteorites, throwing them into space, and floating in space with real meteorites. They encountered some celestial bodies and might be sucked away by the gravity of the celestial bodies. It is through this method that it is possible to find a real life planet.

However, no matter how much Lin Jiang values ​​this matter, the entire Blue Star cannot revolve around this matter, because space exploration is a very ethereal thing, and success or failure depends greatly on luck.

One day in the 8950th year of the Xia calendar, Blue Star welcomed the first batch of interstellar guests. It was not the first time that aliens visited, but before that, they brought killings, and this time, they came as friends.

"Fellow Daoist Ming'an, Fellow Daoist Jianxing, Fellow Daoist Xue"

Lin Jiang greeted Ming'an from Canglan Star, Jianxing from Zinan Star, and Xue from Beiyuan Star in Harbor City, and greeted the three of them.

"Fellow Daoist Lin, how are you ?"

The three of them also returned the greetings to Lin Jiang with their own etiquette. Although their worlds were different, they all learned the Chinese language of Blue Star.

They did not come alone. Each of them brought a large delegation, with a minimum of hundreds and a maximum of thousands of people, ranging from the Jindan stage to the Jiedu stage, and it was estimated that they brought people to see the world.

Lin Jiang also prepared a team of hundreds of people to connect, bringing the people from the three worlds to Harbor City for resettlement, and Lin Jiang and the three of them had a small gathering.

"Fellow Daoist Lin, I rushed here right after I settled Lingfa Star. Sorry to bother you."

"Fellow Daoist Ming'an, you are being too polite. We are friends who have fought together. Our friendship is stronger than gold. I am very happy that you can come to Blue Star." "

Haha, then let's not be polite. This time, in addition to friendly exchanges, I also want to develop interstellar trade."

"I am very happy and welcome to you."

Lin Jiang bowed his hands. Ming'an had told Lin Jiang about this a long time ago. Friendly exchanges are required by the Heavenly Court. The Heavenly Court stipulates that if a planet in the same star field proposes friendly exchanges with another planet, the other planet is not allowed to refuse. It is probably to guard against Buddhist cultivators.

As for interstellar trade, it is probably what Ming'an and the others want. Lin Jiang does not mind it. On the contrary, he welcomes it very much. Lin Jiang does not need to say more about the benefits of trade.

Lin Jiang held a grand welcome dinner for them, and raised the standard of their reception a lot. Several five-star hotels in Harbour City were all requisitioned. As for Ming An and several leaders, they lived directly in Lin Jiang's villa. The villa, which was more than 2,000 years old, was renovated and rebuilt several times, and it still had a unique style. It was a scene in Harbour City.

After the welcome dinner, Ming An and others' team was divided into three parts. One part was Ming An and other big guys, who followed Lin Jiang to appreciate the culture of Blue Star and inspect some industries, while the other part was to connect with some universities and the like. This was academic exchange. They had their own unique skills every week. The last part was to contact the business department to discuss how to trade. After all, some exchange rates, tariffs and the like needed to be negotiated.

········

"The development of Blue Star is not easy."

After visiting a certain science and technology history museum, Ming An sighed. They were not ordinary tourists who came in to take a quick look. They had carefully looked at all the exhibits and had already seen the historical context of the development of Blue Star technology.

"It's indeed not easy. A small alarm clock, a timekeeping device, requires the design of hundreds of industrial chains. Sigh."

Jian Xing shook his head. In his opinion, a small alarm clock had no practical significance, but there were many industries involved, not to mention those large-scale engineering equipment. If it was a high-tech industry, such as chips, it would be even more terrifying. I don't know how many industrial chains would be needed to support it.

"Blue Star's society is like a tight machine, with hundreds of thousands or millions of parts. It can't function without any one part. Our plan to learn from Blue Star is going to fail. We can't build so many industries."

"It seems that we still have to discuss with Lin Jiang, otherwise we won't get any benefits."

Ming An also continued. Before, they secretly hid some warships, robots and the like, and took them home for research, but in the end they didn't research anything. Even though Ming An had studied in college on Lingjing Star, he knew that his knowledge was far behind the top scientific and technological achievements such as space warships.

Now that Ming An has seen the development of science and technology on Blue Star, he feels that the development of science and technology is not easy. If they rely on their own development, it is unknown how many years it will take.

In the evening, Lin Jiang hosted a banquet for the three people, and Ming An also put forward his own ideas.

"Fellow Daoist Ming'an, there's a saying you may have heard before"

"Fellow Daoist Lin, please say it"

"Those who resemble me will die, and those who learn from me will live"

"This..."

"The technological development of Blue Star has its reasons. The right time, the right place, and the right people are all indispensable. Although I have never been to Canglan Star, I don't think you have the conditions for technological development. It's a very simple question. Technological development needs to be driven by interests, and elementary science and technology cannot compare with the means of immortal cultivators. In the early stages, they can't even make a profit. How can we promote technological development, don't you think?"

"Yes, I'm just unwilling to accept it. Knowing that your things are so good, but we can't use them, how upsetting it would be. Fellow Daoist Lin, I know that your Blue Star's technology is patented and valuable. We can pay to learn it, and we will never take advantage of you for free"

"That's easy to say,"

Lin Jiang said with a smile. Since they are willing to pay, it will be easy. It's not possible to give them the entire set of technology, and they can't learn it. Without hundreds of thousands of scientists and engineers, even basic industries cannot be established. However, some things that combine technology and immortal cultivation can be sold to them.

After the banquet, Lin Jiang found the heads of academic and business affairs to discuss the results of the exchange with them.

"The three families' skills all have their own unique features. Two days ago, I exchanged a top-level skill, Thunder Technique, with Zi Nanxing's Tribulation Stage. It is stronger than the Thunder Technique left by the Thunder Emperor and has more methods..."

Cao Ying was in charge of the academic exchange. She had been communicating with the top leaders of the three families in the past few days, and finally exchanged skills with Zi Nanxing's Tribulation Stage.

"Overall, the level of cultivation of the three families is one level higher than ours. However, because they use the traditional method of recruiting disciples, they pay too much attention to the skills. Many skills do not have enough successors, and many have been lost, leaving only the skills in vain."

"Xiaoying still needs to exchange more things, skills, elixirs, talismans, weapons and arrays. Whatever you have, you can exchange. This is a rare opportunity. We are still in the honeymoon period with the three families, so everything is negotiable."

"I know about this. In two days, I will take them to the library of the Cultivation Academy to let them see how geniuses are cultivated under the modern education system."

"What about the commerce department?"

"We are also making smooth progress here. In the future, our transactions will use spirit stones and give each side the best tax treatment. Our Ministry of Commerce wants to organize a caravan to trade on the three planets."

"We can support this. When the time comes, we will exchange more things for us, especially the parts that are scarce."

"Yes, the things of the three families are still very good. We have never heard of some of them. This time we have broadened our horizons. However, some things feel a bit backward. Generally speaking, the raw materials are more attractive, and the refined things don't have much advantage."

"In terms of technology and industry, the biggest advantage is manufacturing, so you just need to follow this feature."

Lin Jiang also nodded. Every world has its own advantages and disadvantages, which is normal. So according to the advantages of Blue Star, if trade is liberalized, he is not worried at all that they will suffer losses in trade. Lin Jiang is even afraid that they will refuse to trade after knowing what a trade surplus and deficit are.
