I Don't Know! Together They Become Green-Skinned.

There is a book in Qidian with almost exactly the same content as what you wrote. Even in the early stages, it was about hitting the dam on humanity. The protagonist's first weapon is a fire hydrant sledgehammer. Orcs Must Live is a bit unfinished at over one million words, but it is still complete. It can only be said that the dozens of pictures at the beginning have exactly the same content, from the time-travel system version to the game time-travel version. In addition to the protagonist's name and time-travel method, the cheating methods are different. The plot, protagonist's skills, protagonist's battles, supporting characters, and main events are all exactly the same. They all give talents through time travel at the beginning, and they all have 1000 meters of morale lock and big guy iron skin, and 50 meters of substitute death. Then we get goblins, and the plot of the goblins scraping their feet to grow mushrooms is exactly the same. Then build a house, gather some boys to rob trucks, and then build a dam. Before building the dam, we seized a scrapped aircraft. The cleaning was done by a skilled sniper. After building the dam, we built the Mao Temple.
