The Great Lust

It turned out that Lands used were just imitations of the actual Land stored in a device that was owned by the Leaders of every Base. 

In the Red Base case, powerful Grade 4s that have the opportunity to come here and convert their Point to Red Lands contribute a Single Coin to the Red Base, that coin will be stored in the device and some smaller Red Coins will be produced. 

Red Base will then exchange the smaller Red Lands with White Land, Yellow Land and Black Land from their origin Bases. 

"Those Normal lands aren't without value. After they circulated around the base and reached the hands of many people they were still gathered and then merged with the original coins. That will improve its power and then it explodes into energy, and that energy will be used to clean the atmosphere from dangerous pollution and keep us humans safe. That was because the coins calculated collect a tiny bit of energy from everyone else to make that happen!"
