The Millennium Wuling Tendon

"What are you doing here?" Gray Wolf asked in a low voice, peered into the courtyard, observed the Master and Ghost Doctor conversing, and then followed Leng Hua to the side. 

"Isn't Hell's Lord cultivating in seclusion? Why did he suddenly leave?" Leng Hua asked. 

It was reasonable to expect Hell's Lord not to leave seclusion at this time, but he did. Could it be that he encountered problems in his cultivation? 

"Master had a mishap during his cultivation. Due to a backlash, his muscles and veins were injured. He said it's fine that you know, but don't tell anyone." Gray Wolf said quietly.

Leng Hua was somewhat surprised to hear this, but it was not entirely unexpected. When the person who was supposed to be cultivating in seclusion came out, he assumed that something had happened. After asking this question, he discovered that Hell's Lord had an accident during his cultivation, even his muscles and veins were injured.
