Lin Feng is a delivery boy. After being angered by a strange customer and breaking his defense, the system was activated.
The rule is simple: if you let someone break their defense, they will become stronger.
So he rode an electric bike and delivered food all the way, making people break their defenses.
Weird clients have broken through, human traffickers have broken through, drug lords have broken through, and warlords have broken through.
In the end, the whole world's defenses were broken - how come this delivery guy is more powerful than the army?
