บท 548: Chapter 88

After completing the preliminary design, Sui Xiong spent some time modifying it, especially the energy source part. The next day, he went to Palin's research center with something shaped like a broom.

The workers just needed to crush the iron ore into pieces and sweep over them with that broom, and then those parts with a higher iron content would be pulled out. After sweeping two or three times, the remaining residue had very little iron content and little value.

As for crushing the iron ore into pieces, there was nothing difficult in that. After all, when it came to iron-making, the smaller the pieces were, the better the effects it would have.

Palin liked the new design very much. After several tests, he offered some suggestions for a revision.
