Chapter 908
Year 9,350 of the Blue Star Xia calendar, Huaxia
With the constant improvement of the interdimensional teleportation array, the communication between Lingfa Star, Lingkong Star, Canglan Star, Beiyuan Star, Zilan Star, Lingjing Star, and Blue Star has become more and more frequent.
Basically, every year, the trade caravans come back and forth, and each time the size of the caravans increases, from dozens of people at first to hundreds, and finally to nearly ten thousand.
The exchange between different civilizations on various planets is naturally a good thing, and its benefits are countless. For the Blue Star civilization, it is also very important. After years of communication, the understanding of the Immortal Language has improved a level.
However, everything has pros and cons, and the downsides should not be overlooked. The two biggest problems are species invasion and bacteria and viruses.
The problem of species invasion is serious, not only between planets but also within the same planet. Lin Jiang feels strongly about this.
After all, on the former Blue Star, Lin Jiang had heard the story of the billions of rabbits in Australia. When people in Huaxia hear about the billions of rabbits, they can only think of plate after plate of spicy rabbit heads, but Australia truly had no way to deal with them. No matter what methods you use to kill them, you can never get rid of them; they reproduce too quickly.
There are countless similar examples. There are simply too many, and it is indeed a very serious issue for the ecosystem, which could lead to ecological collapse if not handled properly.
The problem of bacteria and viruses is just as serious. Back when Lin Jiang was online, he saw posts from travelers saying that soul transfer was fine, and there was not much problem. But if it was a physical transfer, with all the bacteria and viruses from a modern person, it would be like bringing a walking plague to ancient times.
