Once the combat training was sorted out, Senku put in a tremendous amount of effort to add another function.
Now neither power generation nor the furnace needed manual labor, freeing up more people to help elsewhere and prepare for the spring.
Meanwhile, Chen Yu had started some grueling work of his own.
He wanted to make Kinro a suit of armor, not one made entirely of iron, but protective gear made of iron plates linked together with thread.
Since Chen Yu had no idea how the plates on those suits of armor were made, he could only produce them a little at a time, then hammer, shape, cool, and connect them.

Now Chen Yu bitterly regretted focusing so much on medicine and other unrelated fields back then.
It was his own idea, after all. He had to consider not only the weight but also its defensive capabilities. It really was mentally exhausting.
What Chen Yu was doing also caught Chrome and Kaseki's attention.
