Chương 517: Chapter 515: The Great Return Origin Pill

```

Under the faint moonlight, Chu Yi was propped up on the ground with some difficulty, his head drooping, his entire head steaming with heat, panting like an ox, his breath on the verge of extinction.

"Did you use a forbidden technique?" Chu He's complexion changed slightly, and she asked with a worried look in her eyes.

The sudden surge in Chu Yi's strength during the battle had not gone unnoticed by her, as had his rapid descent into extreme exhaustion once the fighting had ceased.

"No... it wasn't a forbidden technique, just a momentary excessive consumption of Qi-Blood," he replied.

Chu Yi slowly raised his head, smiling at her somewhat casually.

Just now, Liu Aotian, who had activated the first layer of the Yin Puppet Transformation, possessed such formidable power that if Chu Yi had not used his trump card that burned his Qi-Blood, he would have had to use all his techniques and endure a bloody battle before he could possibly win.
