By the coast, a hundred-meter Star Gate shimmered with flowing light.Beyond the Star Gate, an army forged of steel stretched as far as the eye could see.Above the Sky Dome, squadrons of fighter jets streaked across, weaving an iron curtain.In the distant ocean, scores of aircraft carriers, destroyers, and frigates dotted the seascape, ready for action.All cannons were aimed at the figure who emerged from the Star Gate.“In the name of the Federation Command Center, I order you to stand down, or what awaits you is total war,” said the voice.“War?”Gu Jinlai took a step forward, and his form swelled against the wind, in an instant growing from less than two meters tall to a colossal Chaos Demon God thousands of kilometers high, emitting the brilliance of a white dwarf star from his being, his own gravity causing thunder and lightning, as well as tsunamis and tides within a thousand-mile radius.He looked down...At the war weapons that seemed like toys.He reached out, and a hydrogen bomb fell into his hand.Within him, the electron-degenerate star core released Helium, Helium elements expanded, and the terrifying high temperature instantly caused Deuterium and Tritium, Hydrogen's isotopes, to fuse, the energy bursting forth, forming a blazing white brilliance on the ocean's surface that was like igniting a sun.Before this sun's energy could be released, he clapped his hands together, and the dazzling white, mixed with heat in the billions of degrees, was compressed and sealed within his palms, not a fragment escaping.“I think, you should choose peace.” he suggested.

Xiao Shan is a famously profligate prince, the kind that makes his emperor father angry just by being seen. Xiao Shan’s greatest wish in life is to be a salted fish who lives without any worldly strife, until his father bestows upon him Xie Zhui, a ger who has been mixing with men, to be his bride. Xie Zhui took his brother’s place in the army at fourteen, achieved great merits by successfully defending against enemies outside the northern border city at sixteen, and was discovered to be a ger after being seriously injured at eighteen. After returning to the capital, the emperor pardoned Xie Zhui’s crime of deceiving the monarch and bestowed him to Xiao Shan as his rightful spouse. Everyone says that Xiao Shan has married a ger who came out of a pile of men, with a vast grassland above his head. They think about how much the emperor must dislike Xiao Shan to have given him such a troublesome marriage.
