Lu Heng returned to Qionghua Tianglu Lake and took out the Metal Enhancement Crystal Core, handing it to the Mechanical Tiger, saying, "Try this, there's a Skill Slot, it should be able to absorb the energy inside."
Since he had never obtained such a Mechanical Beast before, he wasn't clear on how they absorbed the Skill Crystal Cores.
Anyway, the data panel showed that there were 3 Skill Slots, so it should be able to absorb it.
The Mechanical Tiger opened its mouth and swallowed the Crystal Core.
Lu Heng placed his hand on its large head, feeling the icy cold metal with his palm while staring at the data panel.
After about ten minutes, the data panel of the Mechanical Tiger finally showed a change in the skill section.
"Skill: Metal Enhancement"
"Metal Enhancement: Enhances Metal Element abilities, increases metal hardness, impact resistance, and element resistance by 50%."
Then, Lu Heng drew the Aurora Blade and chopped the Mechanical Tiger with the same force as before.
