Chu Ji also had deep regrets in her words. Indeed, this small underground land cannot bear too much life. The number of life will make her live happier, although she is just a smart life and a civilized and wise brain.

"When our civilization reached its peak, it had a population of 320 billion, and it completely controlled the life planets in the nearly 655 star systems near the solar system, and countless mineral resource stars. It was also considered a middle-level civilization in the Milky Way. At that time, the underground world was coming and going, but later because of the war, everyone was involved in the battle, and there were fewer and fewer people here. Until the last person left, I was the only one left." Chu Ji fell into her memories, and her voice was filled with deep sadness. It was conceivable how powerful and prosperous the Tiansheng Empire was at that time.

But even such a powerful cosmic civilization will have enemies, and they will be completely defeated by the other party and destroy the country and the clan. You can imagine how cruel and cold the universe environment is for the race of life.

It would be better for the little girl to be happy. Although she has a long age and is also a simple intelligent life, Yun Yi didn't want her to be sad. She pointed to a huge forest not far away and asked:

"That's what kind of Shu Chuji, it seems to be more than 100 meters tall, right? It's so exaggerating!"

"That's purple-gold sandalwood. What you are talking about now is a kind of sandalwood. Its wood color is naturally purple-gold, and the wood grain is beautiful and charming, and has a strong fragrance. This fragrance has a calming effect on ordinary people and is even more helpful to practitioners who practice original energy. The surface world has long been extinct. Since it was discovered by intelligent life, it has made them feel that this is a precious wood and a specialty of our earth in the universe. However, its growth is slower than their descendants. So if you enter the interstellar era in the future, it can exchange a large number of resources for you."

"That's what I've gained today? And it seems that the woods are very big, and it seems that several people can't hold each one together?"

Yun Yi said with some surprise, especially Chu Ji emphasized that the future he entered the interstellar era, which means that these wealth will belong to him in the future.

"Of course, this is the result of my continuous planting for countless years. There are more than 500,000 purple-gold sandalwood trees here. There is also a kind of Chuyang fruit in the distance, which is also a specialty of the earth. It can also be exchanged for countless cosmic wealth. However, the fruits of Chuyang fruit have been wasted here for countless years, because no one transported them to the trade star for sale." Chu Ji proudly replied to Yun Yi, and his voice gradually became low.

Yun Yi, who knew the other party's mood, did not continue this topic.

"How do you plant them? It seems that you are talking to me out of thin air!" This is indeed what Yun Yi is puzzled.

"Stupid, of course, it's an intelligent robot. I have a large number of nearly 100,000. Although their intelligence is very low, they are also my partners. As for talking to you, of course, the entire underground world is under my control, and there is no omission. In the past, I controlled the population and territory of the entire empire. Everyone was doing nothing and did not hide it from me, but now they can only control this underground world."

Her emotional transformation speed caught Yun Yi off guard, and her tone was already filled with obvious contempt. This may not be her intention, but in fact, Yun Yi is indeed a local bully for future technology compared to her.

"There are two types of specialties that are valuable in the universe. The others are primitive animals and plants for you, and they only have research value. Go home, I know you have a lot of doubts, and I can tell you everything I know."

Just when Yun Yi was wondering how to get there, a floating speed flew into the sky. It seemed that civilizations that had developed to a certain extent loved bright silver. The speed parked in front of him was this color, which was somewhat similar to the vehicle on the earth, but it was much more sci-fi and much bigger. The perfect streamlined body made people like it at a glance.

"After all the people in the empire sacrificed, the energy stones stored here are no longer sufficient, and I also use small transportation vehicles that save energy as much as possible. Although I can replicate the energy stones and there are energy factories here, there are not many ores that can be recharged after all, and they can only maintain some basic uses of the underground world and keep it intact for tens of millions of years." Chu Ji thought Yun Yi was dissatisfied with the small car in front of him and explained.

Of course, Yun Yi would not show that he liked this speed car very much. He had no reason not to like these technological products that were obviously beyond his knowledge.

The vehicle door automatically opens, which may be the former family car. The interior space that can accommodate at least six people seems very spacious, especially when Yun Yi is the only passenger. The seat is made of light yellow material, and the soft and smooth feel makes people think that this is made of animal fur.

"This is a seat made of new materials in the future world. Technology has developed to a certain extent. Many commonly used clothing and other things are replaced by new materials. It has the function of automatic cleaning, and its defense ability is super strong for you at present. At least the so-called gunpowder sniper rifle in the surface world cannot cause any damage to it. It also includes the impact force of the bullet, not only its flexibility cannot be destroyed by guns. It can be said that as long as humans wear it, even if they are hit head-on by a large-caliber sniper rifle, it will be unscathed."

Chu Ji's explanation made Yun Yi speechless. Is this just ordinary material so exaggerated?

Yun Yi didn't ask again, and Chu Ji didn't mean to explain again, because these things were indeed ordinary things for her. She immediately controlled the speed vehicle to rise to the sky and flew towards the center of the mainland.
