What does it mean for Lao Huang to take the sword box?

In "Fierce Knife in the Snow", Lao Huang opens his heart with a sword box, and then he goes to the martial city to challenge Wang Xianzhi's peace of mind.

The sword box is used by Lao Huang to hold his own sword, which contains six of the top ten swords in the world today. Lao Huang used the sword box to achieve the reputation of "Nine Yellow Swords". Visible Lao Huang's sword box is the most important weapon of Lao Huang, and after he died in Liang Wudi City, Lao Huang's sword box stayed in Liang Wudi City.

When Xu Fengnian picked up the sword box from the bottom of the lake, he knew it was Lao Huang's favorite thing. However, it was such a casual move that drove Lao Huang to a dead end. The moment Lao Huang took the sword box, he strengthened his determination to die.

As expected, in the competition of Liang Wudi's sword challenging Wang Xianzhi, Lao Huang died of exhaustion, and the sword box and the famous sword in the box naturally stayed in the city of Liang Wudi.
