Jiang Ci handed a small black rectangular box to Shi Qian on the bench by the lake. "Here, this is for you."
Shi Qian looked down at the box in his hand. "For me? Is today a special day?"
Jiang Ci smiled. "It's not a special occasion. Someone gave me a tiny toy. I thought you might like it, so I gave it to you."
"What is it?" Shi Qian took the box.
"Open it, and you'll know."
Shi Qian opened the box. Inside was a short bronze arrow that looked quite old.
She took the short arrow out of the box and looked at it momentarily before she said, "This is an ancient sleeve arrow, right?"
"The sleeve arrow was one of the hidden weapons in ancient times.
"Hide a weapon in the sleeves. The lethality was still quite mighty in the cold weapon era of ancient times.
"A soldier would usually use it in battles between two armies. Some escorts and boxers would also use it for self-defense."
Jiang Ci nodded.
