Alien Fake Invasion, I Live Broadcast Building a Dyson Sphere

The World Consortium created a live reality show. False news of alien invasion. I want to see how different people will react to such news.

Thus, Lin Jiang single-handedly started the technological revolution! Mathematician: "Lin Jiang has proved almost all mathematical conjectures, and there are not many conjectures left for us..." Physicist: "Lin Jiang has completed the grand unified theory. If he hears it in the morning, he will die in the evening!" Electric vehicle manufacturer: "How did Lin Jiang achieve an electric vehicle range of 10,000 kilometers? This is unscientific!" Materials scientist: "This material developed by Lin Jiang will change the photovoltaic industry!" Lin Jiang: "My Dyson ball is finished." The whole world is shocked! A year later, the alien fleet entered the solar system... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
