Great Walls Everywhere 长城可随处建造
仍调试中……
长城可随处建造，在山脉或自然奇观单元格建造长城后公民可在该单元格工作并可作为穿山隧道。
目前bug：
1.无法站在陆地上往海里建长城，只能站在海里才能在海里建，结果就是必须等造船术和航海术
2.仍无法在地热裂缝或奇观上建长城
Still Debugging……
Great Walls can cross mountain and be built Everywhere. Citizens may work on Mountains and Natural Wonders tiles after Great Walls were built on
Problems Remain:
1.Great walls can’t be built on water unless builder is standing in
2.Great walls still can’t be built on Geothermal Fissure or Natural Wonders.
