The sentient Mechs of the Mech Kingdom could also evolve, through killing Mutant Beasts, defeating their enemies, and obtaining all sorts of treasures in exchange for contribution points. They could then exchange all these for parts, enhancing themselves to the limit, before going through the Evolving Temple of the Mech Kingdom to upgrade to a higher-level Mech. Therefore, such points were extremely important.
Yue Zhong then had an idea, "I've already enslaved a dozen Mechs, with almost 10 million worth of points. If I want to exchange, I need to grab one of these sentient Mechs and infiltrate the Kingdom."
10 million points were worth about a few million Type 4 Nuclei. It was a sizeable fortune.
The Mech Kingdom was extremely advanced, with enough contribution points, they could produce weapons that could threaten Type 8 experts as well. If Yue Zhong could obtain a few of those, then there would be some insurance against the Mech Kingdom.
