I Am the Villain of Both Worlds! Help the Country Fill up Its Technology Tree

[National group favorite + cool article + soft technology to rejuvenate the country + lord + alien war + revenge does not last overnight] Su Yu: Officer! I have a portal! Police officer: Did you eat too much? Until that silver door appeared out of thin air. The country is shocked and I have become a state secret? Also became an alien leader and arms dealer? I used food and weapons from the Dragon Kingdom to go to other worlds in exchange for extraordinary resources. Every transaction is accumulating wealth and power for the Dragon Kingdom. Yingjiang: "Oh Maiga! Why can't the Dragon Kingdom fighters get rid of them?" Long Guo: "Tell it to my PL-15P!" Foot Pot Chicken: "Baga! You said the people from the Dragon Kingdom are above us? But why do I only see white clouds when I look up!?" "Marquis Su, where is my money?" "The territory makes money and the territory flowers, I want to take them home!" "Team Su, there is oil in the Vampire territory!" "Oil? This is the echo of money! The synthetic brigade sets off!" "Captain Su, the orcs are coming!" "Second Battalion Commander, pull out my electromagnetic gun!" From a single person passing through, to thousands of troops crossing the border. From trade exchanges to technology crushing magic. When the Eagle Sauce Alliance shows off its muscles in the territorial waters, they will see magical technology from another world. When the natives from another world are still looking up to the gods, they will see the torrent of steel from another world.
