He really wanted 'Second Egg' to help him polish the steel ball.
But 'Second Egg' was busy doing elementary math, and Ma Lin felt embarrassed to disturb him.
Polishing the steel ball himself was very slow, and the more anxious he got, the slower it became.
Only a well-polished ball could be used for bicycle bearings.

The next day, someone joked about him, saying he delayed the construction time. For the two-story cement building, the world's first, Ma Lin forgot to prepare cement slabs for the door and window openings, so bricks couldn't be laid above the openings. He had to quickly make the cement slabs.
The cement slabs he tested himself were qualified.
Cement poured into a pool, with enough steel reinforcement in the middle, adjusting the proportion of each component in the cement would form the slab.
