As for the symbiosis limit that Senior James mentioned...
It might be because his purity is not high enough.
After Jiang Chen symbiosed with the primeval mecha, he didn't feel any burden, nor did he perceive any limits.
At the very least, symbiosing with another ten or eight mechas would definitely not be a problem.
He placed his hand on the shattered steam mecha, and unleashed his mecha-pilot symbiosis ability.
It easily disassembled and devoured into countless fragments, completely absorbed into his body.
The clockwork mecha soul representing Yun also fell into a slumber deep in his soul, located right next to the vine flames.
"Mecha souls sitting in a row..."
"If I symbiose with Yuu, would they be able to play fight-the-landlord in the depths of my soul?"
"When there are many mecha souls in the future, the ones not participating in the fight can come back into my body to play mahjong, right?"
Jiang Chen barely held in his laughter.
