He Jie twitched at the corner of his mouth; this indeed was like Zhang Fei doing embroidery.
Although embroidery needles are also made of metal, the difficulty of driving them into metal is imaginable.
What's more, to use a two-meter-wide shield, the wind caused by just flapping the shield could blow the embroidery needle away.
"What's the progress?"
"Currently, out of ten embroidery needles, one or two can be stopped."
Liang Kuan pointed at the target surface.
Some thin, twisted marks were imprinted on it.
"What about the skills for advancing to Tier Two, not practicing them?"
"I've practiced one called 'Iron Bone,' but it requires the advanced skill 'Steel Muscles and Iron Bones.' Director Xu is summarizing the training method, and the other 'Metal Muscle Tendons' also needs some preparation."
As soon as Liang Kuan spoke, He Jie matched these two skills in the database.
