Cao Ziqing stared at the bowl that was almost shoved into his mouth, his cheeks twitching violently several times.

It was evident that his mood was extremely awkward.

The flesh on his cheeks twitched uncontrollably, unable to stop.

If it weren't for the fact that the Divine Doctor really had some skill earlier, he would have already wanted to smash the other with a palm strike.

Xuanyuan Lingfeng was dumbfounded, staring at the "Divine Medicine" in the bowl.

"What is this situation?"

The so-called "Divine Medicine" for restoring spirit, qi, and mind, turned out to be...

A mouthful of phlegm?

And judging by the color of this phlegm, it seemed the Divine Doctor was a bit inflamed recently.

Can this stuff cure illness? Can it really enhance virility? Is this a joke?!

Beside them, Ning Qingyuan almost burst out laughing.

"Without this essence of spirit, qi, and mind, your state is nothing but outwardly strong but inwardly weak."

Lin Hai's calm voice rang out.

Upon hearing this, Cao Ziqing's face twitched violently again dozens of times.

Is this stuff for curing illness? Are you sure it's not meant to nauseate someone to death?

However, when he looked at Lin Hai, he found that the Divine Doctor's expression was completely unperturbed, as if making someone consume... a mouthful of phlegm was the most ordinary thing.

"Strange, judging by the Divine Doctor's demeanor, it seems countless people have eaten his... cough, cough, that's just too disgusting."

Cao Ziqing had the illusion that perhaps the Divine Doctor was telling the truth.

But asking a dignified Super Young Master of Yanjing to consume a mouthful of phlegm… It's an insult greater than death!

"Master… Can this stuff really cure illness? Besides, I'm basically recovered now, the talk of spirit, qi, and mind feels so vague…"

Cao Ziqing spoke with difficulty.

"Eat it or not, this essence of spirit, qi, and mind is priceless." Lin Hai replied lazily.

"This..."

Cao Ziqing really didn't understand, can a mouthful of phlegm restore the so-called "spirit, qi, and mind"?

Ning Qingyuan felt that Lin Hai was definitely doing this on purpose to disgust Young Master Cao.

"This essence of spirit, qi, and mind of mine can cure all diseases, and if you take it, even ordinary poisons won't harm you at all."

"But it's a pity, people are ignorant, only seeing superficial things without understanding the essence and core."

Lin Hai shook his head and sighed.

Xuanyuan Lingfeng's eyes shifted as he contemplated.

"I have a proposal," he suddenly said.

Everyone instinctively looked at Xuanyuan Lingfeng, including Cao Ziqing.

"Since the Divine Doctor said that this phlegm… uh no, this spirit, qi, and mind can cure all diseases and is immune to poisons, why not conduct an experiment to verify it."

"What kind of experiment?" Cao Ziqing caught the question.

"Since the Divine Doctor said that spirit, qi and mind can counter common poisons, why not catch a small animal, feed it poison, then give it a bit of phlegm, uh no, spirit, qi and mind, to see if it can detoxify?"

After Xuanyuan Lingfeng finished speaking, he closed his eyes, feeling so clever.

Cao Ziqing also revealed a sinister smile, looking at Lin Hai, he said, "Young Master Xuanyuan is right, whether you're fooling me or not, an experiment would show, Divine Doctor, what do you think?"

After speaking, he deliberately squeezed his fist, making a cracking sound, clearly intending to threaten.

Ning Qingyuan's eyes showed signs of panic.

"It's over, Brother Lin is definitely just bluffing." Ning Qingyuan was even more worried.

Soon, under orders, a servant returned with a pure white little rabbit and a bottle of unknown liquid.

Xuanyuan Lingfeng took the bottle, shook it casually, and smiled at Lin Hai, "Divine Doctor, this bottle of liquid was called Crane Crown Red in ancient times, capable of killing someone in seconds, don't know if it fits your description of ordinary poison?"

"It fits, just a mere Crane Crown Red, even if it were Intestine-breaking Powder or Heart Devouring Grass, my spirit, qi and mind would neutralize it." Lin Hai replied.

Cao Ziqing and Xuanyuan Lingfeng showed shock in their eyes.

Intestine-breaking Powder, Heart Devouring Grass, those are several levels above Crane Crown Red in terms of toxicity.

Crane Crown Red cannot harm the Supreme Strong.

But Intestine-breaking Grass and Heart Devouring Grass can harm the Supreme Strong.

Especially Heart Devouring Grass, which can kill a Supreme Strong.

"The Divine Doctor's tone is so grand, wonder what his expression will be when his spirit, qi and mind fail to work later, hmm, I'm really looking forward to it."

Xuanyuan Lingfeng thought to himself.

Although he was impressed by Lin Hai's medical skills, for some reason, Lin Hai's calm demeanor and gaze always reminded him of the hateful Lin Hai.

And the more they talked, the more he grew to dislike him, even though he couldn't explain why.

Anyway, right now, he really wanted to see this indifferent divine doctor make a fool of himself.

"Bring the rabbit over."

Xuanyuan Lingfeng grabbed the little rabbit in his hand, it seemed to sense danger and struggled continuously.

Ning Qingyuan couldn't bear the thought of such an adorable little white rabbit being poisoned.

"No!"

She stepped forward to stop Xuanyuan Lingfeng from forcefully feeding the rabbit poison.

"Miss Ning, what do you think you're doing?" Xuanyuan Lingfeng glared at her angrily, as if looking at a servant.

"The little rabbit is innocent."

"Innocent? Without the rabbit, how do we conduct an experiment? Do you want to do it yourself?" Xuanyuan Lingfeng snorted coldly.

"Fine, I'll drink the poison, spare the little rabbit." Ning Qingyuan gritted her teeth and said determinedly.

By doing so, she could help Lin Hai and save the rabbit's life.

"Oh? That's even better, using a person for the experiment could be more direct." Xuanyuan Lingfeng revealed a sinister smile, indicating a certain disregard for others' lives and a bloodthirstiness.

Lin Hai's face turned cold.

"Experiment with the rabbit!" Lin Hai said coldly.

"Divine Doctor, isn't using human lives better?" Xuanyuan Lingfeng asked, puzzled.

"Then there's no need for this experiment, this treatment is over, and we need not meet again." Lin Hai snorted angrily.

Cao Ziqing, afraid of never being able to win Lin Hai over, quickly said, "Then let's use the rabbit for the experiment."

"Heh, Miss Ning, shouldn't you thank the Divine Doctor, you're a branch of the Xuanyuan Family, your previous offense was disrespectful, but in respect to the Divine Doctor, I'll let it go." Xuanyuan Lingfeng said with a smile.

Ning Qingyuan's face turned livid, gritting her teeth, for the first time finding the Xuanyuan Family so detestable.

Soon, the little rabbit was forcefully fed the poison.

Watching the poor little rabbit squirm in pain on the ground, Ning Qingyuan felt extreme heartache.

"Feed it the spirit, qi and mind."

Cao Ziqing ordered, then parted a tiny bit of the "spirit, qi, and mind," feeding it to the rabbit.

Next, everyone was waiting, wanting to see if the Divine Doctor's spirit, qi, and mind truly worked.

Xuanyuan Lingfeng was ready to cause trouble for Divine Doctor Lin, prepared to act at any moment.
