"I don't know either. In fact, I have pondered over it countless times over the past hundreds of thousands of years, and the general formula has already come out. I think I may be able to figure it out if I try a few hundred more times. Of course, maybe I'm unlucky, and I won't be able to figure it out even after trying thousands or tens of thousands of times." Taotie thought for a while and said.

Mu Hanyan frowned. She hadn't known the potency of the decoction, nor the pain she'd endure after taking it, so she hadn't taken it seriously. She'd simply tried it a few more times, since Taotie looked like he had no shortage of herbs. But now that she knew, how could she be willing to let Jiang Qiling suffer this torture hundreds, thousands, or even tens of thousands of times?

Taotie’s method doesn’t seem to work!

After a long while, Jiang Qiling's empty eyes finally regained a hint of clarity, but they were still filled with exhaustion. Her entire body was drenched in sweat, as if she had just been pulled out of the water.

"Are you feeling better?" Mu Hanyan walked forward and took out a pill and gave it to her as usual.

"Much better, thank you." Jiang Qiling replied weakly, took the pill and swallowed it.

Although in the illusion of life and death, whether it is practicing or taking pills, it is of little use in improving cultivation and healing injuries, but it is still somewhat useful in restoring physical strength.

"Have a good rest." Mu Hanyan said sympathetically as she looked at Jiang Qiling, who looked tired, as if she had just recovered from a serious illness.

"No need, I'm fine now. Come again." Jiang Qiling struggled to stand up and said through gritted teeth.

Mu Hanyan looked at Jiang Qiling in surprise. She remembered that not long ago, she was trying to commit suicide and was determined not to help Taotie test the elixir formula. She had changed her personality so quickly.

"I heard from you that Zhan Yuan is so powerful. It won't take long for him to find the Phoenix Nirvana Fire. With my father's strength, he is probably no match for him." Jiang Qiling said with a wry smile.

She had witnessed Mu Hanyan's strength with her own eyes. When they were in Beiyuan Mist Plain, their actual combat power was not much different from their father's. As one of the four legendary ferocious beasts, Taotie's former strength was self-evident. Even they were so wary of Zhan Yuan and the magic dragon, and Taotie was seriously injured by them. How could they imagine how powerful Zhan Yuan was?

Although her heart couldn't help but tremble at the thought of the pain when the drug took effect, she had no choice but to give it a try for her father's safety.

It's just a little pain, and I won't die anyway. I can just bear it and it will pass. Jiang Qiling comforted herself in this way.

Seeing the worry and persistence on Jiang Qiling's face, Mu Hanyan couldn't help but be moved.

"There's no need to rush. Take a rest first. I'll go prepare herbs for Taotie." Mu Hanyan insisted on pushing Jiang Qiling back, and then came to Taotie's side.

Without her saying anything, Taotie had already begun sorting the herbs. The situation was so critical, and it was rare for Jiang Qiling to change her mind, so of course he had to hurry.

"What kind of herb is this?" Mu Hanyan said, pointing at a herb that Taotie had sorted out.

Seeing Jiang Qiling’s previous miserable condition, Mu Hanyan always felt that Taotie’s method was a bit unreliable, and she still had to think of a solution herself.

However, the other party was an old monster who had lived for millions of years and had worked hard to learn all kinds of strange and unusual skills in the human cultivation world. She did not dare to act too arrogantly.

"This is called Yunxin Grass, it has the effect of nourishing the heart and strengthening the soul. Don't underestimate this herb. Even before the separation of the Holy Continent, it was a rare and exotic flower. After the Holy Continent was divided into two, the rarer the herbs, the harder it is for them to survive. Even if they survive, their medicinal properties may change drastically and they cannot be used for alchemy at all. Yunxin Grass is one of them. Only in the illusion of life and death can Yunxin Grass survive and maintain its previous medicinal properties. Now you should know the mystery of my illusion of life and death. Only I, the Great Taotie..." Taotie answered casually.

Trapped alone in the illusion of life and death for hundreds of thousands of years, even the most quiet and introverted person would be bored, let alone a boaster like him. So when Mu Hanyan took the initiative to talk to him, he was extremely happy and answered every question. Of course, at the end of the conversation, he couldn't help but brag.
