So does such a liquid truly exist?
If it exists, Ma Lin's piston sealing can be further improved.
For several days, he has been testing in this manner, but has not yet found a liquid that meets his requirements.
Perhaps they do not exist.
Perhaps the airtightness of his cylinders and pistons cannot meet the requirements at all, and using liquid to seal the gaps is impossible.
Now, no one is supervising what he does.
After all, everyone saw what he accomplished last year.
Some simple improvements to machinery don't necessarily require his intervention.
But people kept coming to ask him whether this or that improvement would work, and some ideas were so bizarre they left Ma Lin dumbfounded.
Primitive people cannot correctly understand these mechanical devices, and they view electricity almost religiously.
Ma Lin explained that lightning in the sky is also electricity.
