Take the trunk of a sapling and slowly process it. After a long time, it meets the requirements.
The stick with many coils in front has an official name in the Hua Nation, called the 'warp lifting stick'; the coils below also have an official name, called the 'heddles'.
The warp lifting stick can lift hundreds of vertical threads through the heddles, creating a difference in height with other vertical threads.
There are hundreds of warp threads in the cloth, and the warp lifting stick lifts every other warp thread.
This way, by passing a weft thread once, hundreds of weaving actions are completed.
Then, the tensioning tube presses these lifted warp threads back to their original position, completing another weaving.
Because the goal is to weave coarse threads, and Ma Lin still has many questions about this weaving method, he wants to conduct more experiments.
On a certain day, he began to make a smooth straight stick, slightly over a meter long.
