Capítulo 726: The Difference Depended On His Mood

Su Yun was observing whether there were bubbles in the warm saline water. When he heard the voice speak up, he knew who it was.

Without raising his head, he asked, "Old Lu?"

Uh... The person who came in was stunned. He did not expect to know who he was without raising his head after meeting him a few years ago.

If Zheng Ren was here, he would definitely be ashamed.

Zheng Ren would definitely not know who he was face to face, but Su Yun could tell just by listening to his voice.

"You don't even call me 'Brother Yun'? Why are you still calling me Su Yun?" Su Yun's eyes were staring at the water's surface, trying to determine whether the bubbles were coming from his lungs or from the air accumulated in his chest.

This was a test of skill but for Su Yun, it was not difficult at all.
