After all, there is still a big difference between people who have studied martial arts and ordinary people. The reason why Ji Beibei didn't notice this difference at the first time before was that most of the people on the road were similar.

Everyone is almost all practicing martial arts.

Even if they are old, weak, sick and disabled, Ji Beibei will feel that they are different from ordinary people who have really not learned martial arts?

All the people practice martial arts--

The corners of Ji Beibei's mouth turned up, and he looked at Ji Aizhen: "Sister, if I didn't meet me when I came out today, I really didn't know that everyone had started to learn martial arts."

It seems that I really paid too little attention to the outside world before, and I began to lose touch with society. Tell me about it again, apart from this, is there anything different about the past two or three years and before? ”

"Haven't you always been doing the right thing? People's energy is limited, and you are busy developing new life-saving drugs all day long. It's also normal to pay little attention to these things. ”

Letting Ji Beibei hold his arm affectionately, Ji Aizhen and Ji Beibei continued to walk forward, thinking about it while walking: "It's different, in addition to this, we can really buy things now." No matter what you buy, you don't need a ticket anymore? ”

"What about other than that?" Ji Beibei looked at her, "What else?" ”

"What else?" Ji Aizhen thought about it carefully, then her eyes lit up and she smiled, "Don't you think the air has gotten better?" Especially at Kyoto University, I feel that the aura is a little stronger. ”

Got a bit of aura?

Ji Beibei looked up and looked around, and suddenly his eyes were fixed on the street trees that could be seen everywhere on the side of the road - she was not mistaken, wasn't that the golden thread willow that was famous for improving the planetary environment in the interstellar world?

When did even the high-level interstellar civilization that was scarce, expensive, and not easy to feed become a "big road cargo"?

Ji Beibei's eyes showed a hint of doubt.

Could it be that the climate and soil of the capital are just right for the survival of this golden thread willow?

If so, that's great. No wonder my sister feels that the aura is strong, it should be that the campus of Beijing University has not planted this golden willow.

Sure enough, seeing that she suddenly stared at the golden thread willow without saying a word, Ji Aizhen's attention also shifted and said with a smile: "Do you also think this kind of tree is beautiful?" ”

Ji Aizhen: "This tree is called golden willow, and it will exude a very light fragrance. It makes people smell very comfortable. Every time I get tired of reading, I like to stand under this tree, and I feel that my spirit can be restored by standing under the tree.

You just said that there are still some changes, if this kind of tree counts. In the past two years, not only in our capital, but also from many students in our school, the street trees in many cities in various parts of the country have been replaced with this golden willow. ”

"It's being used as a street tree all over the country?" Ji Beibei looked at Ji Aizhen in surprise, "Sister, are you sure?" ”

"The more strange you feel?" Ji Aizhen laughed: "Actually, it's not strange at all, the main thing is that this golden willow looks beautiful, smells good, can refresh the mind, and is relatively easy to survive, so it's not normal for major cities to like to use it as a street tree?" ”

"Easy to survive?" Ji Beibei smiled at first, and then nodded again, "Well, but maybe it's really our Sea Blue Star's environment that is more suitable for this golden willow, right?" So it was really our luck. ”
