What's the name of Zhu Xian 2' s 32-explosive necklace? How to get it!

I took 275 Xuanyuan Bao Tong and 300 Xuanyuan ancient coins in my bag and exchanged them with the old man who picked lotus in Qingyun. I got a necklace with a level of 140, which increased the explosion damage by 32%. Take a snow star and go to the old man opposite the flying fairy in Qingyun, and God will punish him by strengthening the spirit of snow. The level will be changed to 100, which can be worn, increasing 32% critical injuries and 500 HP.
