Yang Wen takes over a film and television company on the verge of bankruptcy, without even any artists, and is planning to sell the company to stop losses, when he accidentally binds to the "Ancient Extra Summoning System". System ability: summon real ancients from various ancient time-space to cross over to modern film sets as extras to shoot movies; "extra notice fees are settled daily, Yang Wen takes ninety percent, the ancients take ten percent". The money earned by the ancients can be used to purchase supplies in modern times, take them back to their own ancient world, and directly change the historical trajectory of their original world.
