Chapter 999: Chapter 998: Waiting for Him Alone

To tell the truth, without using the Yin Yang Heart Flame, manufacturing a Level Four Elixir poses quite a challenge for Yusuf Zuck.

If he used the Yin Yang Heart Flame, he could concoct a Level Four Elixir with his eyes closed, since his telekinesis is strong, combined with the Strange Fire Yin Yang, there's no problem with Level Four Elixirs.

However, he's currently in an assessment and mustn't reveal the secret of the Yin Yang Heart Flame. Didn't Rafael Case say so? If he exposed the secret of the Yin Yang Heart Flame, even the college dean might jump out to snatch it at any cost.

Who wouldn't covet one of the nine Strange Fires under heaven?

Therefore, Yusuf Zuck needed to use his own Heavenly Immortal Fire along with his considerable telekinesis to refine the Level Four Elixir in his hand, and thus, he had to ensure that there were absolutely no mistakes.
