Xiao Yi and Sun Ming have already checked these forty cards. These forty cards record various technologies, including electromagnetic pulse guns, miniature nuclear fission reactors, and controlled nuclear fusion. However, the ones that attract Xiao Yi and Sun Ming the most are the sky fortress and the overlord on the sea.

However, these two technologies are too expensive. The sky fortress requires 200 points and the sea overlord needs 100 points.

Among them, the air fortress is a huge suspended aircraft similar to the space-based fortress. It can hover at high altitude and is very large in size. It can carry a large number of combat units such as fighter jets, mechas, etc. It has living facilities inside, residential areas, entertainment areas, combat command centers, etc. At the same time, the air fortress is equipped with various turrets and machine guns. There are four very powerful particle ejectors at the tail, which can provide powerful power for the air fortress.

The maritime overlord is also a giant creation similar to an air fortress. Its function is similar to an aircraft carrier, but it has submersible functions, but can only travel at sea or in wide waters.

Xiao Yi and Sun Ming were very interested in these two technology blueprints, but they were too expensive. Sun Ming evaluated these two technologies and said: "These two technology blueprints are indeed worth this price."

In desperation, Xiao Yi and Sun Ming checked other technologies, but Xu Lin said: "Information can also be exchanged for a certain number of points, such as information about the 'third eye'. This information is priceless. If there is complete information, it will be enough for you to change to an air fortress."

Xiao Yi spread his hands: "It's a pity that I don't know much about this information."

Xu Lin sighed and pretended to be disappointed, saying, "Yes, I thought you knew this very well. After all, your sister can open the third eye like a few people."

Xiao Yi raised his eyebrows and became confused. A few people?

"It seems that only the indigenous people on this planet can open it. I will call it eye opening for the time being, but judging from the current situation, it seems that the ability of each person's eye opening is also different. Unfortunately, I don't know much, and I can't find a seller who knows this information."

Xiao Yi did not respond. He flipped all the 40 cards and asked, "Do you only trade the technology blueprint?"

Xu Lin smiled and said, "Others are OK, such as intelligence, materials, and cherishing species, but it's a pity that because the world overlaps too quickly, I didn't have time to bring my huge warehouse, so many good things were left in that world, but it doesn't matter, I can start from scratch, and I brought these most precious technologies here... Have you chosen it?"

Xu Lin said it half true, and Xiao Yi also understood that he could not trade some precious materials and species. Whether it was technology or intelligence, he would make sure to make a profit, because if you copy one, you would have another one.

But when the materials and species are traded out, there will be no more, especially those materials and species brought from other worlds, which are even more expensive, so how can it be traded easily?

After thinking for a long time, Xiao Yi finally picked out three cards and handed them to Xu Lin: "Select it!"

Xu Lin was surprised after seeing it: "Oh, don't you choose the overlord of the sea? I thought you would need such a mobile base."

Xiao Yi said: "It's too expensive, and with our current production level and funds, we are not enough to build such a giant creation. I think we should be practical, first strengthen our strength, and then exchange it with you after we get good things in the next world overlap. Similarly, if you get the technology of the space-based fortress, please remind us."

Xu Lin nodded and said, "A wise choice, um... I'll look at these three technologies, electromagnetic pulse gun, 'Alien Dog' genetic modification technology, exoskeleton power armor, um... The total value is 40 points, and you still have 5 points left to use. If you don't want technology, why don't you get some information?"

Xiao Yi nodded, and then Xu Lin started to ask the maid robot to get the intelligence card. During this period, Xu Lin asked: "Can you ask why you chose these three technologies?"

Xiao Yi said: "It was chosen for our current shortcomings. Although we have a blueprint for magical technology guns, the production cycle of magical technology guns is too long. The electromagnetic pulse gun can be mass-produced quickly and can be assembled on robots. At the same time, it can also produce electromagnetic pulse sniper rifles, electromagnetic pulse machine guns, electromagnetic guns, etc., which will supplement our long-range strike means and heavy firepower suppression means."

Xu Lin nodded: "The genetic modification technology of the alien dog was chosen to defend the base. After all, the base is full of electronic equipment and robot guards. If you encounter a hacker, it will be done. If you have an alien dog protection, it will be much safer. The manufacturing method of the alien dog is also very simple. Just inject the genetic modification agent into the body of an ordinary dog."

"That's right!" Xiao Yi said, "As for the exoskeleton power armor, it is considered that our fragile human body cannot block bullets and explosions. However, with this armor, it can increase our defense, especially for mecha drivers. After all, mecha drivers have no combat power after leaving mecha. With exoskeleton power armor, even if the mecha is damaged, they still have the ability to save their lives."

Xu Lin said in agreement: "Double protection? A good idea, this technology will have a greater temptation to the military, well... you wouldn't plan to sell it to the military if you change it, right?"

Xiao Yi just smiled but didn't say anything.

The current situation is unclear, so of course you have to keep the good things for yourself. Xiao Yi only plans to trade these technologies with Xu Lin. After all, Xu Lin has more good things, but he does not have the plan to trade with others.

And this exoskeleton power armor was actually prepared for Sun Ming, Mr. Lan and Li Feng.

At this time, the maid robot walked over with three data storage and another deck of cards on the plate.

"This is the technology you want." Xu Lin pushed three data memories over, and Xiao Yi said to Sun Ming: "Start checking."

After saying that, Xiao Yi pushed the technology of the Magic Mecha and the base car over, so that the equivalent exchange of items was temporarily completed.

Xu Lin pushed a deck of cards over: "These are 17 pieces of information, and the values ​​vary. You can exchange them with the remaining 5 points, or you can suspend transactions. When you come back next time, my products may be richer."

Sun Ming opened his computer and began to check the data of the three technologies. Xiao Yi looked through these 17 decks of cards. These 17 decks of cards are about intelligence, and the next time the overlapping location of the world is also in intelligence, but the value is only 1 point.

In addition, there is also the location of the Black Dragon that appeared in City D, with a value of 7 points and the locations of some visitors from other worlds, with different values.

But there is an information Xiao Yi was very interested in, that is, the hidden location of the Archangel Space-based Fortress, and the value was exactly 5 points.

This space-based fortress is simply the most perfect base choice. With the current human technological level, it cannot pose a threat to the space-based fortress in space.

When Xu Lin saw Xiao Yi holding a card, he explained: "Tell you a brief moment. The sky-based fortress is not in space now, and he will not fly into the sky even in the near term, because it does not have enough energy and materials. The energy and materials consumed by the sky-based fortress are not affordable by personal financial resources. Without a strong country as a backing, the energy and materials of the sky-based fortress will be consumed sooner or later, so this sky-based fortress is now hidden in a corner of the earth, and they may be planning a conspiracy to seize power in a certain country."

Xiao Yi raised his head: "I want this information."

Energy? I am a mobile super energy library, and we only have a few people in total, but we can’t consume much supplies. The most important thing is that this space-based fortress is ready-made and does not require huge amounts of money or time to be built. Just grab it directly.
