Before thinking about completely solving Tang Yue'er's Celestial Yin Meridian, Qin Chuan had already anticipated that the process would be extremely difficult.
But when he formally began to condense the Yin Dan for Tang Yue'er, he realized that the process was far more difficult than he had imagined.
The main difficulty was that he had to remain extremely vigilant and must not absorb any Celestial Yin Energy.
Therefore, he couldn't use any of his cultivation, and could only use the purest medical skills to condense the Yin Dan for Tang Yue'er.
Moreover, although the Kunlun Divine Poison in his body had been suppressed, it wasn't without the possibility of erupting again. He feared that if he carelessly absorbed the Celestial Yin Energy, it would disrupt the balance inside his body.
"Hold on!"
Looking at the painfully struggling Tang Yue'er, Qin Chuan said in a deep voice.
