This is his first attempt at forging a level 10 top-grade armament. So he is being very careful.
He has been working on it for 57 hours. He hasn't eaten or rested during that time. He didn't accept any requests for communication during that time either.
His mother has been trying to reach him for a while. He doesn't know what she wants and he doesn't even know that she has been trying to reach him for a while because he put his identity card on mute.
Speaking of his mother, she has helped him to expand his dojo across many cities all over the region. She employed many people who teach students cultivation techniques for free every day.
She didn't do this for him out of kindness. She used the money he sent her to foot her frequent trips all over the region and to employ people to teach in the many dojos she opened for him.
