Daming: the Sun Never Sets, Has the World Traveled Across the World?

My name is Zhu Gaoye, a time traveler and the fourth son of Yongle Emperor Zhu Di. After binding the "Sun Never Sets Empire System", I spent ten years giving my father a small gift: Marched north to Mongolia and drank from Lake Baikal; Going south to the Western Ocean, the fleet's route was around the world; The Fuso Islands in the east are now the royal horse farm of the Ming Dynasty; The New World to the west has been renamed Xinjinshan Province. Just when I was lighting up the first steam engine and preparing to have a showdown with my dad and start the Ming Dynasty's industrial revolution... With a rumble, the sky changed. [The era of global time travel has arrived, and all human beings in 2035 AD will be transported to 1421 AD! In an instant, the whole world was boiling. However, when they appeared confidently on the territory of Ming Dynasty, everyone was dumbfounded. Eagle Sauce Traveler: "Thank God, this is undeveloped North America! Brothers, let's build a great country... Wait, what the hell is that building that says Xinjinshan State Administration of Taxation? Don't catch me! I don't want to memorize the "Three Character Classic"!" Great Britain: "Our sailing battleships will rule the oceans! Huh? What is that on the sea level? A black smoke-emitting giant made of steel? Is that the Ming Dynasty's coal ship? Help! Our fleet was hit and sunk by the coal ship!" Footrest Samurai: "Rebuild the glory of Bushido today! His Majesty the Emperor is on board! Sir, why do we wear miners' uniforms and dig coal for the Ming Emperor in the 'Hokkaido Royal Mine'?" … Alas, the pressure in the job of captain suddenly became high.
