Yang Yiyun didn't look at the direction when he smashed down, he just found a place to fall, anyway, as long as he was on the earth, he could find his way back anywhere, and he felt kind.

Yang Yiyun found that he had landed in a city, but the embarrassing thing was that he didn't know that this was the city......

However, judging from the geographical location, he should be in a southern city at this moment.

But the strange thing is that the city today is no longer the same as he left hundreds of years ago, and has completely changed drastically......

Let's talk about it......

The whole city looks bigger, cleaner, and more distinctive.

The layout is more rational and humane, and compared to the city of hundreds of years ago, the city is more livable now.

The main buildings of the whole city are still high-rise buildings, which are more and more huge than hundreds of years ago, and the high-rise buildings look like a huge giant hand, starting from 100 meters, and some of the taller buildings have drilled into the sky.

But it doesn't have the feeling of a steel forest hundreds of years ago.

On the contrary, hundreds of years later, the city has evolved into a real forest.

Because every building is covered with vegetation, all kinds of Yang Yiyun has never seen vegetation, and on the huge buildings, it looks like each building is more like a towering tree.

What's even more surprising is that these vegetation are not movable, unlike bonsai that were put up several times ago, or transplanted on the rooftop and terrace of the open-air balcony to sit and sit.

Instead, they all took root in the walls of the building......

Such a spectacle made Yang Yiyun feel amazed, how could it be possible to grow vegetation in cement?

Isn't it cement?

Yang Yiyun thought about it and released his divine sense to check the building material of the mobile building, and found that it was indeed not a cement material, but it was a more balanced material than cement.

In this way, Yang Yiyun was even more surprised, the material is more balanced than cement, how are these vegetation planted and entered?

Even if you can plant it, how can you keep it alive?

More importantly, aren't we afraid that the roots of these vegetation will damage the structure of the building and cause safety hazards?

One by one, surprises and questions appeared in my heart......

Let Yang Yiyun be full of curiosity about the current earth.

With curiosity, he looked at the structure of a building and the materials with his senses, and finally noticed something different.

However, he found that in addition to being stronger than the cement material, the focus was on the rhizomes of these vegetation, and he found that the rhizomes of the vegetation growing in the building were very small, which was one size thicker than a hair.

But it is huge, it is a curved existence, and the rhizomes of countless vegetation are connected to each other, making the structure of the building stronger and stronger......

As for the destruction of the building by vegetation rhizomes, Yang Yiyun found the answer, and there is a place in the building called the "Wisdom Building Center".

This is where the entire building is used.

The whole building is like a person, and the center of the wisdom building is the brain!

Yang Yiyun's consciousness found that there is an operation department in the center of the smart building that is dedicated to monitoring and maintaining the entire building structure, and in the display screen, Yang Yiyun saw that in the building structure, the rhizomes of each vegetation are all under monitoring, and the staff can fully grasp the growth of the rhizomes of the building vegetation through this operation center......

If a certain plant grows too fast, it will pass through the central operation channel, and the connected water pipe will directly prune off the extra rhizome with a certain water flow liquid, and the corresponding rhizome will find that there is a wilting phenomenon, and will deliver the nutrient solution as soon as possible to let the rhizome grow......

The existence of such a smart operation center ensures the survival rate of the vegetation of the whole building and the firmness and stability of the building, and there is a set of intelligent operation system.

In fact, when Yang Yiyun saw the building construction manual, he found that the current living environment of human beings on the earth and such forest wisdom buildings had already been realized a hundred years after he left the earth.

So far, this is the fourth version of this urban structure, also known as the permanent version, and will be able to exist forever.

This is the product of the combination of technology and extraterrestrial species, and the history of mankind has changed dramatically a hundred years after he left Earth, that is, six hundred years ago.

In the past 600 years, the motherland has realized the dream of great rejuvenation, and has achieved the world's first level in science and technology, military, politics, commerce, and so on.

Time has proved that the community with a shared future for mankind proposed by the Chinese leaders is correct, and the world harmony has been completed in 600 years.

Today's China deserves to be the center of the earth.

Under the leadership of the Chinese Empire, the countries of the world have long ended the era of energy competition, and now they have stepped out of the earth and looked at the sea of stars.

After Yang Yiyun left for 700 years, science and technology have now reached a new world, and the goal of space immigration has been completed in the past 100 years, and the goal of conquering the stars and seas is being achieved with the progress of science and technology.

The Moon and Jupiter and Mercury initially achieved migration......

Of course, Yang Yiyun knew that the vast starry sky was just a speck of dust for the human beings on the earth.

However, it is a good thing that the earth has achieved world harmony and peace.

The era of energy competition has shifted from the earth to outer space, preserving the life of the earth's environment, which is a great progress under the leadership of the Chinese people.

The vegetation of the buildings you see in front of you is a reflection from outer space or alien planets, which has been used by scientists in the construction industry, completely upgrading the city to a real urban forest stage, and the air has been improved in the first fifteen years.

From a building to a city, Yang Yiyun learned about the development of the earth today, and his colleagues who are moving in a good direction and are also happy in their hearts have become extremely curious about the earth today.

Retracting his senses, he restrained his whole body breath and turned himself into an ordinary person, wanting to take a walk and take a look.

At this moment, on the edge of the city where he landed, in a weedy ditch, dozens of meters away were high-rise buildings, ready to enter the city to have a look.

Looking down at the clothes on his body, his heart moved, and he took out a set of clothes that he left seven hundred years ago from the Qiankun pot space and put them on his body, facing the monkeys who were wearing ancient costumes and became onlookers.

That's how it went......

"Whoosh......"

As soon as he got out of the grass and arrived on a road, there was a swishing sound overhead, something flew by, Yang Yiyun looked at it, but found a ...... with a sense of science and technology A car or a speeding car passes overhead......

This scene made him feel very emotional, but he was not too surprised, science and technology have been developed for hundreds of years, and it is not strange that there can be flying cars.

Looking up, the speeds of the speeding cars flying overhead are likely to reach thousands of speeds per hour.

The flying car flew directly into the halfway waist of a building in Yang Yiyun's sight, and in his mind, there was a whole system of flying car parking in the building.

With curiosity and eagerness to try, Yang Yiyun quickened his pace and thought, looking like a dense urban agglomeration building.

The building where he is located is relatively low, but it is also 100 meters high, and you can see the building drilling into the sky in the distance, Yang Yiyun wants to come here to the suburbs, where is the center of the city, right?

Five minutes later, Yang Yiyun saw that there was a bus stop on the side of the road, and twenty or thirty people were standing, similar to the scene of waiting for the bus hundreds of years ago.

He quickened his pace and walked, he hadn't done a bus for hundreds of years, Yang Yiyun wanted to relive it, and when he returned to Earth hundreds of years later, he was now curious about everything and interested in everything.

When he arrived at the bus stop, he had long white hair and a shawl, and the clothes he was wearing were out of place with others, which immediately attracted everyone's attention.

With a smile, Yang Yiyun gestured to everyone.

But in my ears I heard a whisper of discussion.

"Wow, handsome man......" This is the voice of a young girl.

"This guy is from that crew? I haven't heard of a crew filming today...... Looking at the clothes on his body, it should be a documentary of the revival era......"

"Why doesn't that flowing white hair look like a wig......"

"Ding-dong-ding-dong...... YHY No. 666 smart cloud car arrived at Yuncheng suburban station, about to go to the city center station, 30 kilometers away, it takes three minutes, welcome all citizens to take this cloud car, please get on the bus in an orderly manner......"
