God: Various creators&inventors(solving various difficult diseases on earth)!
The god said, "In the future, the earth wants to shake its body and do preventive work."
The problems to be solved in repairing the earth include:
1). Prevent earthquake {(length or width) >= high proportion structure};
2). Prevent strong wind {space mesh structure};
3). Prevent mudslides {dig a trench and a hole to dissipate heat, use sea water to cool the earth, ...};
4). Prevent floods {use steps or space corridors or ...};
5). Prevent terrain change (tide + loose + soft) {foundation + concrete [Soil Fired(tile) + Stone Powder] +...};
......
How to resolve changes in terrain type?
Use concrete as a foundation to prevent animals from burrowing and squirming move.
To prevent water intrusion and water penetration, dams must be built to prevent too much water.
The interior of the earth is too hot, causing tumors and dense masses that need to flow out to form mudslides.
All of these may cause earthquakes.

Alloy skeleton = {Alloy skeleton walker or Alloy skeleton road or Alloy skeleton staircase or ...};
If you want to build up skyBuilding, it is better to build a MagicSkyAlloy skeleton first because which can prevent {earthquakes + strong winds + floods + mudslides + terrain change + ...}. All natural disasters will be useless!
Let the "alloy skeletons" prevent {earthquakes + strong winds + floods + mudslides + terrain change + ...} around the world!

If the ground cover has some problems, old builings will collapse when the slope of the ground maybe greater than 10 degrees.
But "VerticalLand + SkySkeletonBridge" can be kept safe at a ground inclination of less than 45 degrees.

How to bigger our earth?
Of cause create&make unlimited "VerticalLand + SkySkeletonBridge" on the earth!
