Travel Through Time and Create a New World with Cities and Systems

Tan Gui'er traveled through time and space to a bunch of sons who cheated on the city lord and his wife. Then Beibo took the city through. But Tan Guier is not alone! He has a powerful system! "City Lord, there are so many monsters in this alien world. What should I do if we can't solve them with technological weapons? City Lord!" It's okay, I brought you alien technology! "City Lord, there is magic in this other world, how can we compete with them!" It's okay, we can learn magic too! "City Lord, City Lord, a cultivator appears on the opposite side! What to do!" It's okay, we will use our superb skills! Defeat them! ............ Perfect defense? Swordsmanship? Spiritualism? Or maybe a high-tech Gundam? The anime he watched and the games he played in his previous life are Tan Guier's strongest backing. "It's time for guys from other worlds to get to know the power of the earth's civilization!" Tan Guier shouted at the intruder while holding up the cold Frostmourne. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
