His entire family perished in battle; he rose from the ashes to conquer the world.

His body convulsed with pain, but he kept his eyes fixed on Su Wanqing, his gaze carrying not only pleading but also a commanding tone.

"I...I need to completely...completely change my current physical condition..."

"Relying on the marrow-absorbing powder to maintain this condition won't last long. Next time, it's very likely it won't be able to hold up."

He understood that this time, it wasn't just the "Marrow-Sucking Powder" that mattered, but also his inhuman and terrifying willpower.

However, no matter how strong one's mental state, it's useless against such a frail body. On the contrary, the body will be unable to withstand the strain, causing it to fall apart more quickly.

From now on, when you join Zhan Yang, you'll face life-or-death battles. If your body suffers even the slightest mishap, you'll die!

He needs a body that can match his powerful mental strength!

Upon hearing this, the word "madman" flashed through the minds of both Qin Hongxiu and Fang Yuyan.

Don't you even care about your life? Instead of thinking about saving your life, you're thinking about becoming stronger?

A hint of hesitation flashed in Su Wanqing's eyes.

She scrutinized Mu Yuan, examining his face contorted in agony, yet his eyes burned with a mad rage.

After a while.

Su Wanqing sighed and made a difficult decision.

"I know a way."

She spoke softly, yet her words caused a violent ripple within the tent.

"In the medical archives of my Su family, there is a forbidden ancient prescription. It cannot cure diseases; it only gambles with life."

"Gambling with your life?" Fang Yuyan asked, puzzled.

Su Wanqing stared intently at Mu Yuan and slowly said, "This ancient prescription is called 'Heart-Changing and Bone-Corroding Soup.' Its effects are incredibly domineering and brutal. It will first drain every bit of your vitality, bones, blood, and potential. Once you survive this inevitable death, you will be able to be reborn."

"At that time, your body will be reborn, with exceptionally strong blood and energy, and your congenital ailments will no longer affect you."

She stopped abruptly at this point, and when she spoke again, her tone had turned icy.

"However, the pain you endure during this process will be a thousand times greater than what you're experiencing now!"

"According to the Su family's records, no one has succeeded in the past few centuries. Some could not endure the inhuman pain and died on the spot. Others had their consciousness completely extinguished, becoming mindless living dead."

Finally, Su Wanqing added one more sentence.

"No matter how strong your will is, it's impossible to withstand that kind of inhuman torture."

For a moment, the tent was deathly silent.

Qin Hongxiu and Fang Yuyan couldn't help but gasp, their hands and feet turning icy cold.

Is it a thousand times more painful than he is now?

Is the outcome death, or becoming a living dead?

What kind of prescription is this to save lives? It's more like a torture device designed to kill people!

As soon as Su Wanqing finished speaking, the temperature inside the tent seemed to drop by more than ten degrees, making people feel cold.

Qin Hongxiu's hand unconsciously gripped the hilt of her sword at her waist, her knuckles already turning white. Fang Yuyan's mind was also blank, devoid of any thoughts of business. She bit her lower lip, her usually calculating face now filled only with deep fear.

Their gazes all fell upon the man who was curled up in pain, like a shrimp.

Mu Yuan didn't have time to answer.

He barely managed to endure another wave of excruciating pain before he had a brief moment to catch his breath. He greedily inhaled fresh air, like a drowning man grasping at a straw.

His eyes turned bloodshot, his clothes were soaked with sweat, and his vision was blurred.

He tried to wipe it, but he didn't even have the strength to lift his hand.

Inside the tent, only Mu Yuan's heavy breathing could be heard. After a long while, he finally mustered some strength and very slowly propped himself up, leaning against the headboard. But even this simple movement exhausted all his energy once again.

"Second Sister-in-law." Mu Yuan's voice was as hoarse as a whetstone.

"Then I'll trouble you to prepare the herbal medicine as soon as possible."

"Mu Yuan!" Qin Hongxiu suddenly stepped forward, seemingly not only wanting to push him back, but also to suppress his thoughts. "Did you understand? Wanqing said you were doomed! You're just physically weak; with careful recuperation, although you can't go to the battlefield, you can still live! You are the last man of the Mu family; we can't afford any more accidents!"

"Is this how you live?"

Mu Yuan's gaze shifted to his sister-in-law. She used to be so dashing and heroic, but now her eyes were red, filled with anxiety and sorrow.

His face was calm, and anyone could tell from his calm that he had made up his mind and would not change it.

"So, I'm just going to be chained to the sickbed in the Prince's mansion like a dead dog? Let you women fight to the death while I linger on? Or am I just going to watch Prince Ning and his men slowly and meticulously remove every last piece of flesh and blood from the Mu family, leaving no one alive?"

He suddenly smiled, a weary smile, tinged with indescribable sadness.

"It's too late, it's too late, sisters-in-law."

"Besides, living like that would be more painful for me than death."

Qin Hongxiu opened her beautiful mouth wide, wanting to say something, but couldn't utter a word. Everyone could see the resolute look in his eyes, so what use would it be to try to dissuade him further?

Mu Yuan then turned his gaze to Su Wanqing, his tone without the slightest hesitation.

"Second sister-in-law, I'm willing to drink this medicine soup."

A fierce storm finally broke out in Su Wanqing's usually gentle and quiet eyes.

With a sigh, she didn't try to persuade her further, but simply nodded slightly.

She is both a doctor and the daughter-in-law of the Mu family, and she knows very well what the Mu family needs right now.

The most urgent matter is not to lie at home recuperating so that one can continue the family line in a few years. By then, the Mu family will have been devoured by Prince Ning and his ilk, leaving not even a bone fragment.

Now, what is needed is for the descendants of the Mu family to step forward, displaying the ferocity and power of wolves, to lead the Western Army into battle, and to intimidate all the treacherous villains lurking in the shadows.

"Since you've made up your mind, I'll prepare immediately." Su Wanqing's voice quickly regained its composure, even carrying a hint of coldness: "The medicinal herbs are all readily available and can be brewed quickly. However, the 'Heart-Changing Bone-Eroding Soup' is extremely potent, requiring continuous bathing for a total of forty-nine days. If it's interrupted even for one day, the patient will suffer a fatal outcome of reversed blood flow and broken bones."

"I have one more request."

Mu Yuan suddenly spoke, causing Su Wanqing, who was leaving the house, to stop in her tracks: "Speak."

"The daily bath and medicinal bath must be administered between 9 PM and 3 AM," Mu Yuan stated resolutely, leaving no room for negotiation, as if issuing a military order. "Furthermore, no matter what terrible state I become each day, you must find a way to make sure I can stand up the next morning."
