Aliens on Earth: I Want to Go Back to My Home Planet

Alien Wang Hao traveled to Earth 790 billion light-years away from his home star. In order to return to his home planet, he must raise the earth's technological level to a second-level cosmic civilization in a short period of time before he can build a space shuttle to return. At the beginning, a high-frequency solar collector was built, detonating the sun, bathing the entire solar system in green light... In the first year when 5G was just popularized, Wang Hao's improvements directly skipped the 678 level 3 and entered the 9G era! One by one, inventions that surpassed the times were invented in his hands like children's toys... The earth has entered the era of technological explosion. As long as you can think of it, there is nothing that I cannot build. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
