Skill Shards

Explorers found out that discoverers and enablers were plotting to divide the world, they were very angry and attacked them. But unfortunately, the mech technology of discovers and enablers already belonged to the most advanced level at that time. After a fight, Explorers took the opportunity to smash the crystal in Hill Lode, and the shards of it were scattered all over the world. Later, the Mech Union discovered that the crystal shards had the opportunity to stimulate the potential of the mech, which would give it a chance to learn skills.
