"I don't know!" Regarding Ran Xiaoxiao's question, Ye Feng could only shake his head helplessly and said.

Ye Feng, who has experienced the end of the world for twenty years, actually has a certain understanding of the end times, and also knows that the energy that supplies this big willow tree to grow wildly is not solar energy, but dark energy that fills the entire space.

The visible objects in the universe, stars, planets, and free gas and debris in the universe, including black holes, account for only 5% of the total mass of the universe, and the remaining 95% of the mass is dark matter and dark energy.

Among them, dark energy accounts for 75% of the total mass of the universe, and dark energy cannot be seen or touched, but it is real, permeating all corners of the universe, supporting the expansion of the universe and the main energy of space.

It's just that human science and technology are limited, and they can only observe and deduce the existence of dark energy, but they can't use dark energy, but under the illumination of this mysterious colorful light, it has completely changed the creatures on the earth, so that the creatures on the earth have undergone some changes, so that dark energy can be used.

However, Ye Feng didn't want to say it, because even if he said it, Ran Xiaoxiao wouldn't understand, and Ye Feng didn't have too much experience to explain.

Although the concept of dark energy has been put forward before the disaster, and some scientists have also made logical reasoning, and have also calculated the role and distribution of dark energy on the universe, and even formed a relatively complete set of dark energy theory.

But all this is only based on theory and speculation, and there is no real study of dark energy, nor has dark energy been obtained.

Therefore, for this kind of extremely mysterious thing, Ye Feng naturally will not explain it to Ran Xiaoxiao, even if Ye Feng can explain it, it will make Ran Xiaoxiao feel suspicious, after all, this kind of thing is difficult for even scientists to explain clearly, but Ye Feng can say that the head is the Tao, how can it not make people doubt.

Seeing Ye Feng shaking his head, Ran Xiaoxiao didn't continue to ask again, just now he just asked casually, and he didn't expect Ye Feng to answer, this is just an instinctive inquiry when people encounter incredible things.

Under the driving of Ye Feng, the off-road vehicle is very agile and fast, even if the road conditions are bad, it can reach a speed of more than 80 yards, at this speed, in less than a few minutes, it is already far away from the big willow tree, and the huge body of the big willow tree has disappeared in the rearview mirror.

The off-road vehicle galloped all the way to the east, the road was very desolate, at a glance, it was green, as if it had fallen into a green ocean, and the off-road vehicle was like a lonely boat floating on the green ocean, firmly and slowly sailing in the green ocean.

There are hardly any human footprints to be seen here, and the abandoned vehicles on the highway have been covered with green vegetation, and these vehicles covered by green vegetation are slowly dissolving.

The plants that cover the car can secrete a strong corrosive liquid that constantly dissolves the car, and it won't be long before most of the metal on the car will be dissolved, eventually leaving behind some corrosion-resistant plastic and tempered glass.

The civilian self-built houses that are vaguely located on both sides of the highway are also covered with green plants, and the reinforced concrete is also slowly thawed under the strong corrosive liquid secreted by the plants.

Generally speaking, it only takes 300 years for a frame structure house made of reinforced concrete to disappear like gravel under the normal decay of the natural environment.

However, now after the corruption of the strong corrosive liquid of green plants, this process is rapidly shortened, only one or two months, these frame houses built of reinforced concrete have been seriously deformed, and even some houses with higher floors have been broken because the steel bars supporting the frame are corrupted.

"What is this place?" Ye Feng, who was originally concentrating on driving the off-road vehicle, his face moved, as if he had thought of something, and suddenly turned his head to look at Ran Xiaoxiao, who was the co-pilot, and asked.

Ran Xiaoxiao, who was sitting in the co-pilot and constantly playing with the little tiger in her arms, heard Ye Feng's question, raised her eyebrows, looked at Ye Feng with a puzzled expression and said, "Yangcheng Realm, right?" ”

Although it is now in a sea of green, with green plants covering almost all sides, it is still easy to distinguish the location based on the terrain and the signs that can be seen on the road, as well as the occasional landmark buildings that appear around.

"Ran Xiaoxiao, are you sure?" Ye Feng continued to ask.

Seeing Ye Feng's somewhat serious and eager eyes, Ran Xiaoxiao gritted her teeth, in Ran Xiaoxiao's memory, Ye Feng was a person who did not smile, and rarely called her by her name, usually what are you going to do, but now you call her by her name, which shows that Ye Feng is very serious at the moment.

Therefore, Ran Xiaoxiao put away her casual heart and began to carefully examine the surrounding environment.

Ran Xiaoxiao turned her head to look around, and recalled carefully, and after three minutes, she turned her head to look at Ye Feng, with a sure face, and said seriously: "This should be Shiyang City!" ”

Shiyangcheng belongs to a county-level city under Yangcheng, because of its superior geographical location, it is at the junction of Tianfu Plain and mountainous areas, and belongs to the transfer station and transportation hub, therefore, it has developed rapidly in recent years, and finally became a county-level city.

80 kilometers to the east of Shiyang City is Yangcheng, after which it completely leaves the mountains and enters the endless Tianfu Plain.

"Shiyang City, Death City, it turns out that this is Death City." Hearing Shiyang City, after seeing the vibrant green around him, Ye Feng's face showed a hint of abruptness, and he muttered to himself.

In Ye Feng's memory, there were two cities that made people smell and change, one of which was Shiyang City.

Siyang City is a city ruled by green, and the whole city has only one color, that is, green, where the plants are extremely lush, more than the primeval forest, but there is no rich ecological chain of the primeval forest.

In Shiyang City, except for plants, there are no animals or humans, whether they are humans or animals, it seems to be the kingdom of plants, plants are the masters here, ruling everything here, and other animals and humans are not allowed to enter.

This place is a forbidden place for human beings, this place is full of mystery and death, in order to uncover the mystery here, there are many high-level human evolutionaries, and even an eight-star peak evolutionary, who is confident of his strong ability, entered Shiyang City, and never returned.

Since then, no human has dared to enter this place, and the name of this place has been changed from the original Shiyang City to Death City, and its name speaks for itself.

"Brother Ye, it's Shiyang City, not Death City." Ran Xiaoxiao, whose Mandarin had reached the first grade, could naturally hear the difference in sound when she heard Ye Feng's self-talk, and hurriedly corrected it.

"It's okay, it's all the same!" Ye Feng, who was caught in a memory, was suddenly interrupted by Ran Xiaoxiao's crisp voice, and his face once again returned to the expression of Gujing Bubo, his eyes were level ahead, and he continued to concentrate on driving.
