I'm in Lingconglang

In an unknown corner, a lifelike statue appeared. The statue looked like a human being. At an unknown moment, the statue shattered, and the giant bug broke out of its shell, turning into a terrifying existence. As soon as they see humans, they pounce on them crazily and start a massacre of humans. They dominate the city. Human beings have no choice but to escape into the wilderness and flee underground. I don't know how many years later, a human wearing a mecha came out of the underground and built a prison into a floating tower. This tower was named "Lighthouse" by later generations. Chen Yu, an ordinary migrant worker in China, fell into coma after he rolled downstairs too fast. When he woke up again, he found that he was in the ruins of a large city covered mostly by sand. From then on, there was one more person in the world with lightning powers. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
