This fully proves one thing.
Human wisdom is limited.
A person can't master everything.
An individual's ideas are also limited.
To push society forward faster, it's best to enhance the vitality of the entire society.
And not rely solely on one's own strength.
The things he can achieve are indeed limited.
He neither has the ability to invent things like soy sauce, vinegar, or MSG, nor can he invent clocks or steam engines.
He needs the power of society.
Not to fight alone.
However, at present, he is far from the limits of his capabilities.
For now, it seems that he at least needs to quickly improve a skill.
His ability in handcrafting metal processing can be improved significantly.
He hopes his handcrafted metal columns can be as precise as machined ones, to the extent of producing hand tractors, not needing to be too beautiful, allowing for some errors.
This is the level achievable by human hands.
Why do it this way?
