Thinking of this, Yang Ming took out the toolbox and began to polish the material carefully. Given the size of the material, it could be processed into hundreds of "flying needles." Although this kind of work could be handed over to a factory outside, Yang Ming needed it as soon as possible. Another reason was that this material was out of the ordinary. If the person who processed this had his finger bleed and found the secret of it, then it would be disadvantageous to him.
Yang Ming planned to use this hidden weapon to assassinate people. If that person had an intention, maybe he would associate it with something. This wasn't what Yang Ming wanted to see.
However, Yang Ming wasn't in a hurry. After carefully processing five pieces, he stopped. It was basically enough to bring these five needles with him. When he finished with them, it wouldn't be too late to craft new ones.
