"Hold on, Ning Yu! Remember what you promised me!" Mu Xue's voice was choked with sobs, but she still suppressed her fear and continuously channeled all her supernatural energy into Ning Yu.

"Cough cough..." Ning Yu coughed hoarsely, feeling as if his body was being pierced by countless steel needles, the pain unbearable. But he knew he couldn't give up like this. He still had many things to do. He still had to protect Mu Xue. He had to take her with him and survive in this cruel world.

He struggled to control his breathing, summoning every last vestige of his supernatural power to fight a desperate battle against that mysterious force. Time ticked by, and Ning Yu's body seemed to be torn into countless fragments, only to reassemble itself again.

Finally, the raging energy gradually subsided, and Ning Yu felt the pain in his body lessen. He slowly opened his eyes; the world before him was blurry, but he still saw Mu Xue's anxious face.

"How are you?" Mu Xue's voice trembled slightly as she gently stroked Ning Yu's cheek, as if afraid he might suddenly disappear.

"I'm fine..." Ning Yu's voice was so weak it was like a mosquito's hum, but he still tried his best to force a smile to reassure Mu Xue.

He struggled to sit up, but his body was as weak as a rag doll. Mu Xue quickly helped him up and let him lean against her.

"Don't move, you need to rest." Mu Xue's voice was gentle yet firm. She gently stroked Ning Yu's hair, her eyes filled with pity and love.

Ning Yu closed his eyes, greedily inhaling the familiar fragrance emanating from Mu Xue. He knew that his survival this time was entirely due to Mu Xue's help and his own willpower.

He secretly vowed that he would work harder and become stronger so that he could protect Mu Xue and stop her from worrying about him.

Suddenly, a soft footstep broke the silence. Ning Yu abruptly opened his eyes, a sharp glint flashing in them.

"Who?!" he hissed, reaching for the weapon at his waist.
