Back then, Zhang Chenfeng faced the formidable Brutal Evil God and ultimately chose mutual destruction.
It wasn't exactly mutual destruction; he merely used his life to seal Brutality on this planet.
He died, but Brutality still lived on.
This was clearly a choice made out of absolute necessity.
Before that, Zhang Chenfeng must have made other efforts.
After all, if one could live, who would choose death?
The pure technological weapons in this warehouse are probably the results of Zhang Chenfeng's efforts back then.
These weapons contain only technological elements without the involvement of Spiritual Energy.
They should have formidable resistance against the Evil God's corrosion.
Using these weapons against the Evil God and Its minions would likely be more effective than ordinary weapons.
However, it seems these weapons ended up lying unused in the warehouse.
