Shen Lian left Diqiu at that moment of time, but ultimately he decided to continue staying in Diqiu.
After all, Shen Lian had injured the High Priest and although he was able to resolve Emperor Xia's dragon fist, his body was slightly wounded throughout the process.
Emperor Xia's dragon fist was a killer blow for all strength training cultivators. When the dragon fist came into contact with Shen Lian, the impact of the punch seeped into Shen Lian's body and ruptured the tiniest blood vessels and meridians. If it was someone else who was taking the punch, the person's organs would have ruptured into a puddle of blood.
It had been a while since Shen Lian had a taste of defeat. Emperor Xia had taught him a good lesson.
Up till then, the impact of Emperor Xia's dragon fist was still lingering inside Shen Lian's body. It was the Primordial Spirit that was keeping it suppressed.
