He raised his hand and looked at it. The skin on the back of his hand was deathly pale, and his eyes could barely stay open—he wanted to sleep so badly.

"This is a sign of severe depletion of vital energy and blood!" Although Henry Walker didn't know medicine, he still understood the basics.

He realized that he might be suffering from a serious deficiency of energy and blood.

He sat at the table, barely managing to support himself, put away the booklet, and then lay down on the bed to rest.

"Qiao'er!"

"Young master? Do you have any instructions?"

Little Grace asked softly from outside the door.

"Go... make me some millet porridge with red dates, and add some ginseng. The older, the better."

Henry Walker said with difficulty.

This was the benefit of being a wealthy young master.

In an ordinary family, not to mention aged ginseng—even regular ginseng was only used as medicine to save lives. How could anyone eat it as a tonic like Henry Walker?

Little Grace responded and quickly ran to the kitchen to give instructions for the porridge.

Henry Walker lay on his back on the bed, trying to catch his breath for a long time, but still felt his vision going black and his limbs weak.

However, aside from these sensations, he was surprised as he stretched out his hand—a familiar, practiced feeling, as if he had trained in blade techniques for many years, surged from his palm into his mind.

The three moves and three levels of the Black Tiger Blade Technique had somehow become second nature to him.

Not only did he fully understand the hidden layers within the moves, but he also knew exactly how the mental techniques coordinated with the moves, the various methods of coordination, the levels, and the applications—all crystal clear.

"It really worked!?" Henry Walker closed his eyes, wild joy filling his heart.

The experiment had succeeded.

Although it seemed to have consumed his body's energy, blood, and spirit, in exchange for mastery of the Black Tiger Blade Technique, it was well worth it.

"It's just that the Black Tiger Blade clearly only has three levels, so where did this fourth level come from?"

This was what Henry Walker couldn't understand.

Moreover, the fourth level of the Black Tiger Blade now felt very familiar in his memory.

It was as if... as if he himself had created it.

The underlying concepts and ideas were not something people of this world could come up with; they seemed more like a fusion of some basic principles of modern science and mechanics.

Although he was just a civil servant, he had at least studied engineering mechanics and human biomechanics in college.

Before he could think further, Little Grace had already brought the porridge.

"I happened to make blood-nourishing porridge for Third Miss, also mainly with red dates. Since she didn't want it, I brought it to you first, young master. This is lily and red date soup, calming and blood-nourishing. I also added ginseng. Would you like it, young master?"

Little Grace asked softly from outside the door.

"Bring it in."

Henry Walker said in a low voice.

Only then did Little Grace gently push open the door and walk in, but as soon as she entered, she saw a spot of blood on Henry Walker's collar.

"Y-young master, what happened to you!!?" Little Grace exclaimed in shock, almost dropping the porridge.

Henry Walker gave a wry smile.

"I'm fine."

"How can you say you're fine! You even coughed up blood!"

Little Grace was so frightened her face turned pale.

"Really, it's nothing..." Henry Walker said helplessly.

Little Grace hurried over and handed the porridge to Henry Walker.

"Here, young master, have some hot porridge first."

With her help, Henry Walker finished the entire bowl of porridge, one spoonful at a time.

He felt a little more comfortable.

He began to carefully recall the new bits and pieces of information and experience about the Black Tiger Blade Technique that had suddenly appeared in his mind.

Strangely, it was as if these things had always been in his head from the very beginning. No matter how difficult, he could easily understand them, and it felt simple for his body to perform them as well.

If his body allowed, he would have gone to the training grounds to find a blade and practice right away.

After he finished the porridge, Little Grace quickly left to find the resident physician of the Lu household. She was still worried about Henry Walker's health.

The Lu household had its own dedicated physician, a thin old man with a goatee.

He hurried over with a large medicine chest on his back.

Sitting by Henry Walker's bedside, he took his pulse, and his frown relaxed.

"Nothing serious, just a deficiency of energy and blood, and mental exhaustion. A few days of rest and recuperation will do."

He pulled out a sheet of paper and quickly wrote down a prescription for a tonic.

"Take this to the pharmacy, twice a day. Have the young master take it for ten days, and he should recover."

"Thank you, doctor."

Henry Walker also breathed a sigh of relief—this matched his own assessment exactly.

Soon, Frank Walker and Andrew Walker also arrived.

"What happened?" He came with Henry Walker's second and third mothers.

Henry Walker's mother had passed away long ago.

He had been cared for by his second mother since childhood.

Second mother Liu Cuiyu was gentle by nature, treated everyone kindly, and showed no difference between him and her own children.

"It's just that I overexerted myself practicing martial arts. It's nothing." Henry Walker explained to his family one by one.

He was the eldest son of the family, the pillar who would inherit the family business in the future. If anything happened to him, it would naturally draw immediate attention.

"Practicing martial arts?"

Andrew Walker frowned.

"Why have you started practicing martial arts again?" He was about to scold him, but then thought of those other young masters who went out seeking pleasure. In comparison, Henry Walker's actions were much more commendable than those of the others.
