Ye Feng nodded as if he suddenly realized something. He had never thought of this.
Ye Feng thought of another question and asked: "When did you come to us? How many such bases do you have on our planet?"
The robot replied: "We arrived here almost a billion years ago. We come from another parallel universe. Travel across parallel universes can only be achieved by energizing matter. Therefore, people who travel here cannot bring weapons or equipment.
When we came here, we started from scratch and developed again. When we were on your planet, we built dozens of bases."
"But hundreds of millions of years ago, there was an alien from Planet Salam who wanted to colonize your planet Panding. Similar planets in our different parallel universes are intrinsically connected. If your planet is colonized, it will rewrite other parallel universes.
Similar to the fate of planets. So we couldn't let them succeed and fought a big battle with them. Because they came here through time and space teleportation and could carry weapons and resources."
"They can continuously deliver materials and supplies, but we can only rely on the dozens of advance bases here to produce weapons and supplies. This greatly limits the number of our soldiers and weapons, and we had a very difficult time fighting that war.
At the end of the battle, we only had a few advance bases left, and the others were destroyed by the aliens from Planet Salam."
"Although the aliens on Salam Planet also suffered heavy losses, they benefited from being in the same parallel universe as you and were fighting at home. In the end, they made a desperate move and sent all the personnel and weapons and equipment that could fight. But at that time we had already
At the end of the battle, there were no reinforcements, no weapons, and no resources. In the end, we were forced to use energy weapons. We released the energy from all our advance team assembly points in a pulsed manner to bombard the opponent's army assembly points."
"We hit the opponent's army gathering point, but it also caused the crust of Panding Planet to fragment, causing the sedimentary rock crust of nearly a billion years to be lost in many places on Panding Planet."
"The aliens on Salam Planet suffered heavy losses and have been unable to recover since then. Later, they had internal strife, so they never had time to take care of Panding Planet, which allowed us to breathe. Of course, this war also cost us a lot, and we are here with you
There are only a few advance bases left on Panding Star."
"The reason why the advance base is still maintained is mainly so that people from your parallel universe can be sent to our parallel universe in the future to help our parallel universe. The reason why we haven't exposed ourselves yet is because your technology has not developed enough to accept our technology.
Our equipment is still too advanced for you and is not suitable to be handed over to you now. We occasionally need to select some of your people to send to our parallel universe to help deliver messages and provide help."
Ye Feng digested the information told by the robot, thought for a while, and couldn't believe it was true. After thinking about it, he asked: "Have you been here for so long without being discovered by humans?"
The robot said: "There are natural dangers in the terrain, smog, and magnetic pole shields. If you want to get in here, you will not be able to get in unless you commit suicide by jumping off a cliff."
Ye Feng retorted: "I didn't commit suicide. Who would come here to commit suicide? I was chased and accidentally fell off the cliff."
The robot nodded and replied: "Oh, that's right. Same."
Ye Feng pretended not to hear. For Ye Feng, understanding the technology mastered by robots is more attractive to him. So he asked again: "Then where does the energy you use to transmit come from?"
The robot said: "Right here underground, we have a particle collider to generate electricity. This method of generating electricity is the most direct and most effective way, and can directly convert mass into energy."
Ye Feng had read some popular science books when he was a child. It was written that scientists from Far Western countries at that time proposed feasibility studies on using particle collision to generate electricity. However, twenty years later, when the ancient Wa country began to invest in research in this field, there was actually an ancient
Scientists from the Wa Kingdom prevented the ancient Wa Kingdom from developing a particle collider, believing that it was a waste of time and money.
Ye Feng thought for a while and asked: "Why don't you use nuclear fusion or nuclear fission to generate electricity? Or other methods?"
The robot said: "Those two methods have been used before in the transition stage, but both energies are unstable and relatively dangerous. We accidentally exploded one at the Tunguska advance base, so we no longer use it."
"The particle collider is a clean energy source with no pollution. And if we need to evacuate, we can just destroy it, but destroying the other two reactors will have a big impact. And other energy sources require different minerals, and we want to avoid being destroyed.
Under the premise that you have discovered it, it is very difficult to mine these mineral resources. So after comprehensive consideration, we finally used this method of power generation."
"And this is the basis for the arbitrary transformation of matter and energy. If humans want to enter the three-point-zero era of civilization, this is the basic technology that must be mastered. If anyone wants to prevent you from developing particle collision technology, he must be your enemy.
"The robot seemed to be able to read minds, or sense what Ye Feng was thinking, and he added.
Ye Feng nodded and continued to ask: "What technology do you use for computers now? Is it still electronic equipment?"
The robot said: "We don't have a computer. We are called an information central integrated processor. Because our purpose is not to process calculations, but to analyze. We do not use electricity, but light."
Ye Feng asked: "How do you use light to perform calculations? How do you miniaturize the light emitter?"
The robot replied: "You have no way to replace integrated circuit equipment with optical equipment now. This is because your optical equipment is still very large compared to electronic equipment. It is equivalent to your electronic equipment being in the tube era. In a few years, you will have optical equipment.
Breakthroughs and the development of smaller optical transceiver equipment can replace integrated circuit equipment with optical equipment."
"As for calculations? We calculate by using different light waves to represent different information. In your words, it is wavelength division multiplexing. We use the wave difference of light waves to perform calculations. Simply put, it is the peak of the light waves passing through within a period of time.
The way of quantity and basic calculation are somewhat similar to the way your mechanical computers calculate."
"In addition, the biggest advantage of using light waves to process data is the wavelength division multiplexing technology of light waves, which is beyond the reach of electricity. The processing of data by optical equipment can be completed in parallel, and the amount of information that can be processed at the same time is geometric.
Class."
Ye Feng nodded to express his understanding and agreement. At this time, Ye Feng's stomach expressed different opinions and began to growl. Ye Feng asked awkwardly: "Do you have anything to eat? What did everyone here eat before?"
The robot seemed to have just thought of something and said, "By the way, you humans need to eat."
As the robot spoke, it turned on a huge machine buried underground, and soon something like a glass of water was sent up from the ground.
The robot handed it to Ye Feng and said, "Drinking this nutrient solution is equivalent to the nutrition you eat in one meal."
Later, another piece of pie-like stuff was delivered. The robot brought it to Ye Feng and said, "I made this based on your pie. You can try it too."
Ye Feng picked up the pie and took a bite, then took a sip of the nutrient solution. The pie was made of beef pie and the taste was very authentic. The nutrient solution had no taste, just a faint salty and sweet taste. It wasn't delicious but it wasn't either.
It tastes terrible.
Ye Feng found something with his eyes and asked while eating: "Where do you grow wheat? The taste is a bit different, it has a refreshing fragrance and is very good." The robot said: "We don't need to plant or breed anything."
Ye Feng widened his eyes and asked, "Then where does your food come from?"
The robot grabbed a handful of dirt from the ground and said, "Here."
Ye Feng said: "It's true, it's not grown from the soil."
The robot shook its head and said, "That's it."
Ye Feng stuttered in surprise: "You, you, you mean, what you gave me to eat was dirt?"
The robot nodded and said: "Yes. As long as you master the method of converting energy and matter, you can convert any matter or energy into food. We have particle collider to produce a steady stream of energy, and use this energy to produce high enough energy.
With high temperature and high pressure, we can transform any substance into each other, or synthesize it."
