73 What's on the Other Side of the Wormhole?

Why were the Iron Heart Exterminators called the Iron Heart Exterminators?

Other than the fact that their "hearts" were literally made of steel, it was also their unwavering "concept of extinction".

Their attitude could be described as "cleansing the universe", which was similar to racial mysophobia.

The only difference was that the racial mysophobia only accepted lifeforms of the same race, while the Iron Heart Exterminators only recognized artificial intelligence.

However, at this moment, the Iron Heart Exterminator on this desolate planet actually began to doubt the ideals he had always carried.

His connection with the Exterminators' central processor had long been cut off. The rational Extinction Unit would not do something as inefficient as retrieving him.

The last command from the central processor was for him to enter a dormant state and wait for an opportunity to kill any approaching organic lifeforms.
