What is the alien world like?

The architectural style of the alien is very modern, unconventional and in line with the comfort of life. When you go out to fly a flying saucer, you will not be rear-ended or stuck in traffic jams. Because he is 1.50 meters tall, he eats less but eats more and wears a flash invisibility cloak. He is good at swimming, can swim for 1.5 hours, and can win the championship in the Earth Olympics.

Now people on earth welcome aliens, and the United States and France have also established alien reception stations. But it will have an impact on the earth's economy after its arrival:

After alien friends visit the earth, the earth's economy will be affected. The biggest impact will be on the aviation, railway, shipping, and automobile industries, because of the flying saucer technology Be popularized, high quality and low price. Then the oil industry collapsed, and the aliens' stellar energy patents became monopolies. The alien dishes in major supermarkets were very popular with ordinary people and were good for health. Earth's vegetables were out of date. People are rushing to buy alien medicine, and many cancer patients and AIDS patients have miraculously recovered; aliens' orders for interstellar laser cannons have made the aliens a lot of money. Commanders from various countries sneer at tanks, submarines, and nuclear weapons and intensify training Space Force deploys interstellar laser cannon. This cannon can destroy an asteroid each time it is fired. In the fifth year since then, the introduced green alien plants have turned the desert into an oasis. Everyone moved to the desert one after another.
