"The technology points added simply by relying on time are simply not enough..."
Zhao Yusi thought about it and decided to decide on the title early so that he could get more technology points.
He did not consider option 2.
Option 1 is a bit extreme after all. He can't directly destroy his native planet.
"Just choose 3!"
[The selection is completed and you will get the title: Mysterious Businessman]
[Mysterious Businessman: You can get additional technology point rewards by trading with alien civilizations. (The science points obtained shall not exceed the upper limit of science points when the trade item was created.)]
[Note: The transaction content is limited to products and does not include scientific theories and related technical principles. 】
After careful study, Zhao Yu finally understood the situation of the mysterious businessman returning the technology points.
For example, using Xiaotian as a trading object, the original construction of Xiaotian cost only 20 technology points.
This means that no matter how many Xiaotians he trades, the maximum number of technology points he can obtain is only 20.
Beyond that, he can only trade what has already been made.
Basic sciences such as mathematics and physics with a technological level of 1.99, or technologies in secondary application fields cannot be used as transaction content.
This shows that he can only sell products, not technology, nor theory.
If other civilizations want to learn from it, they can only do their own research based on their products. As for how long the research will take and whether they can develop it, it all depends on the other party's ability.
"The system seems to be afraid that I will sell my technology to the earth..."
[Tip: The previous host supported the native civilization unconditionally and eventually died unexpectedly. 】
"I see!"
Zhao Yu suddenly realized that the system was afraid that he would die too quickly, so it imposed many restrictions.
This also means that his previous idea was correct. When interacting with the earth, he must not reveal his true identity.
"I was once an Earthling. This is my trump card. Once someone sees it, it means I will lose..."
Zhao Yu didn't need to think about what losing meant. The answer to how he became the new host was all in it.
Thinking of this, Zhao Yu couldn't help but feel lucky. Fortunately, he had been cautious enough over the years.
Not even the housekeeper, Uncle Da, nor the nine highly intelligent androids knew his true identity.
It's not that he doesn't trust them, it's just that he knows there are too many ways to find out the secrets in other people's hearts.
What's more, his level 1 base vehicle has an absolutely loyal population limit of 10, all tied to the butler and nine androids.
Had the system not mentioned this absolutely loyal function, he would not have built artificial intelligence.
Because when facing Uncle Da and the nine people, Zhao Yu would often forget that they were bionic people and would only treat them as real people.
"However, before the transaction, I still need to think about my origins. Although there is no need to tell the people on earth, I need to prepare for it in advance..."
Zhao Yu knew very well that once his base was discovered, it would be discovered that it was an isolated island.
There is no civilization, no large population, no development, a base created out of thin air.
"The background of the people under the moon can be eliminated..."
"The most reliable background is to confirm the identity of aliens..."
Zhao Yu touched his chin, thinking and perfecting it.
"I... no, we came from a distant planet and fell on the moon due to an accident..."
"The spaceship is damaged. It can fly short distances, but it can't travel millions of light years back home. No, you can't say that..."
"Since we are an advanced civilization, we don't know whether it is feasible for a spaceship to reach the speed of light. Perhaps a truly advanced civilization relies on other technologies, such as space jumps in science fiction novels, or wormholes..."
"If this is the case, it is not advisable for the spacecraft to pursue speed blindly. It is equivalent to a beggar imagining that the emperor begs for food from a golden rice bowl. Over time, it will be easily exposed!"
According to the steward's assessment, the average technological level of the earth is only 0.75.
The seven basic technologies in Zhao Yu's hands have reached a level of 1.99, which is already very high compared to Earth.
But he doesn’t understand these things himself, so it’s better to say less in the professional field.
"The light-speed spacecraft cannot be touched. Let's just say there is a technical fault and we can't go back for the time being. Let them guess the rest..."
"The moon base was established to repair the spacecraft. That's it. That's enough!"
Zhao Yu thought a lot, but in the end he felt that it was better to say as little as possible to increase the room for maneuver.
It is better to let the other party think about various possibilities than to have him settle on one direction, only to be overturned in the end and doubt his identity.
After the background was finalized, Zhao Yu began to think about the content of the transaction.
"I won't give it to those in the military field. In terms of daily life, we can't give it to atmospheric environment simulation. If I give it to them, they might want to be my neighbor..."
After thinking about it carefully, he realized that there were not many high-tech products in the field of life. For those technological points, he focused them all on the military.
The existing living facilities in the base were all built by Zhao Yu when he felt bored and panicked and couldn't stand it anymore. Moreover, they were all cheap goods, and their technological content was not much higher than that on Earth.
Zhao Yu accidentally glanced at his watch and his eyes lit up.
"You can trade this, projection touch watch!"
This is a technology that Zhao Yu discovered when he wanted to get a mobile phone after his phone ran out of power when he first traveled through time.
The watch integrates all the functions of a mobile phone, and most importantly, can be projected to air touch control.
"System, if I want to trade this watch, how many technology points can I get back?"
【850 Science and Technology Points】
"850?"
Zhao Yu was stunned. He didn't spend so much money on building this watch.
After thinking for a while, Zhao Yu began to search for all the prerequisites needed to build the watch.
After a series of comparisons, he finally collected 850 points.
It does not include the technology points spent on the seven basic technologies and the technology points of secondary scientific research institutions.
Only the technological points invested in the construction of the four major factories required for manufacturing watches: the optical touch control factory, the ultrasonic sensor factory, the infrared imaging system analysis factory and the signal data processing factory.
"These four major factories were all created by me building other things, and they are actually included in the technology tree of watches..."
"Then if these factories are used in trading other goods, can the technology points be returned repeatedly?"
【cannot】
The system is very sparse with words.
Zhao Yu scratched his head and thought he had found a loophole. It seemed that it had been blocked long ago.
This shows that no matter how he trades, the total amount of technology points returned to him is fixed, unless he continues to develop new technology factories.
"850 points is really good..."
Zhao Yu took another look at the ten previously selected detection devices. He had already built all the required prerequisites and there was no need to pay a second time.
Then these 850 technology points are enough for him to build 10 detection equipment, and there will still be some surplus to prepare the factories needed for the spacecraft.
After solving this problem, Zhao Yu began to think deeply again.
"My products have been selected. What should I ask for from them regarding the earth?"
