The following morning.
After breakfast under Kuisi's service, Lynn left the castle with Red.
Walking on the smooth red brick road, through the large residential area of red brick houses, they arrived at the Blacksmith Workshop.
Lynn continued to immerse himself in the sand mold making for the steel tracks.

With Lynn's continuous labor, the experience gradually increased bit by bit.
The sand mold that Lynn crafted was made from fine sand, screened to remove impurities, specifically quartz sand.
After screening, it was ensured that the sand particles were uniform to avoid air holes during casting.
Clay was mixed with the fine sand in a ratio, keeping clay content around twenty percent.
This was to enhance the mold's plasticity and strength.
Under the watchful learning eyes of the apprentices in the Blacksmith Workshop, Lynn started to make the bottom part of the sand mold.
