Zhang Rongfang temporarily didn't have time to deal with the matter because he had to consider Ding Yu's issue earlier.

Now, with his mind returning to focus, he began carefully observing his own body.

'Don't want to suck blood anymore, but instead want to bleed? What kind of ridiculous impulse is this?'

He stretched out his hand, opening his palm.

With just a thought, a drop of blood slowly seeped through his palm.

And the lost blood in his body instantly replenished the consumption of that drop of blood.

The blood drop rolled around in Zhang Rongfang's palm, devoid of warmth, like a cold, exquisite Blood Jade pearl.

Staring at the blood drop, Zhang Rongfang suddenly had a whimsical thought flash through his mind.

'Since the instinct to absorb blood before made me stronger, could this bleeding instinct also have the same benefit now?'

Immediately, he found a container, a bottle previously used for poison.

Then he pricked it with his fingertip, controlling the bleeding with his thoughts.

Drop by drop, blood continued to drip from his forefinger into the bottle.

As the blood flowed away, Zhang Rongfang felt a slight sense of comfort in his body.

He withdrew his finger and picked up the medicine bottle and shook it.

Suddenly, he inexplicably felt...

A vague, strange feeling.

It was as if he had developed a subtle connection with the blood inside the bottle.

'Could it be...!?' Zhang Rongfang's mind unexpectedly flashed with a thought.

He had long felt that his previous blood-sucking ability was somewhat like the zombies, Blood Race, you had spoken of in his past life.

And now....

He could actually establish a connection with the blood that left his body!

So could it be...!?

Immediately, Zhang Rongfang took the medicine bottle and poured the blood back into his palm.

The blood flowed as if a river returning to the sea, merging into the palm in the blink of an eye, disappearing, returning to Zhang Rongfang's bloodstream.

Everything was no different from before....

Zhang Rongfang fell silent, listening to the wailing sounds coming from Ding Yu next door.

He stood up, opened the door, and returned to Ding Yu's ward.

'Let's give it a try, if I really have the abilities of a Blood Race zombie, then.... Ding Yu's issue might not be a problem.'

Zhang Rongfang looked intently at Ding Yu, causing him to shiver all over.

That gaze involuntarily reminded him of the feeling of being stared at by Xu Mengyan, the master of the Five Cauldrons Sect, before.

"Don't be afraid. I have an idea, let me try it," Zhang Rongfang comforted him.

"Sir... make it quick, I'm already like this now, whatever way can be used should be used!" Ding Yu resolutely said.

Bouts of unbearable itching and pain constantly attacked his entire body.

He suspected that if this continued, he couldn't make it to tomorrow and might consider suicide.

"Alright." Zhang Rongfang nodded, stepped forward, and pressed his hand against the side artery of Ding Yu's neck. 𝒻𝘳ℯℯ𝑤ℯ𝒷𝘯ℴ𝓋ℯ𝘭.𝑐ℴ𝑚

This was his first time sucking the blood of his own people.

And it was the first time not for killing, but for saving someone by sucking blood.

He precisely controlled the speed of blood-sucking.

Zhang Rongfang quickly felt warm liquid slowly seep into his fingertips.

But the warm liquid was noticeably different from the previous blood; it was filled with various living creatures!

They were... bugs!!

Zhang Rongfang took a deep breath.

He finally understood what this World Yang Liquid was.

It was planting parasites in the human body! Letting them fill the entire bloodstream and then along with the blood flowing through all the organs of the patient.

This was essentially an incurable biological poison!

Over time, these live bugs would gradually consume all organs and tissues of the human body.

Luckily, the bugs in Ding Yu's blood seemed to have just awakened and hatched, moving slowly and not too numerous.

These blood bugs, just absorbed into Zhang Rongfang's finger, were about to slowly swim and settle into the new bloodstream.

Immediately it was as if cold water had fallen into a pot of boiling oil, receiving an unparalleled warm welcome.

Zhang Rongfang's blood crazily rushed up, enwrapping them, forming bubbles of varying sizes.

Seconds later, the bubbles dissipated, leaving only pure blood water inside.

Zhang Rongfang felt more heat within his body.

He wanted to bleed even more....

'Could it be that these bugs are actually nutritious for me?'

A helpless thought flashed through his mind.

After confirming that the poison of World Yang Liquid was ineffective against him, he immediately stopped sucking blood from Ding Yu but instead reversed it, pricking his fingertip and starting to block the flow of blood back into Ding Yu.

'If I really have the abilities of a Blood Race zombie, then... I should also be able to transform others through blood!' Zhang Rongfang was experimenting.

He knew that different blood types, if transfused rashly, would cause severe rejection.

But now Ding Yu was out of options.

And his situation was also very special at this time.

He could vaguely feel that he could control the blood he released.

Thus, trying it, treating a dead horse as if it were alive, was better than waiting for death.

Drop by drop, blood was infused into Ding Yu's body.

This released blood almost actively integrated into Ding Yu's blood vessels.

Accompanied by bleeding and merging, Ding Yu clearly felt a trickle of coolness flowing into his neck.

This trickle of coolness was small at first, but it was like wildfire burning through a dried-up prairie.

Quickly from the neck to the head, to the torso, the entire body.

Ding Yu only felt that all the blood in his body was burning.

But contrary to this burning sensation, he felt like he was falling into an endless abyss, sinking continuously, sinking deeper and deeper.

And the itching and pain on his body were slowly disappearing silently with this descent.

Zhang Rongfang, standing by the bed, could now clearly see the changes in Ding Yu.

He was pleasantly surprised to find that with only a small amount of his blood input, it acted like ink dropped into clear water, quickly devouring Ding Yu's blood and then began to reproduce and divide on its own.

They consumed Ding Yu's blood as food, devoured it, then divided, grew, and continued to devour, repeating this cycle.

In just a few minutes, Zhang Rongfang felt as if he could control all the blood in Ding Yu's body!

This feeling was very wondrous.

It was like a part of his own limb had been placed on another person not far away, yet it was still under his perception and control.

Even though the limb had left the body, it should not be perceivable or controllable.

Yet Zhang Rongfang could still manipulate and sense it.

The large amount of new blood devoured all the living worms in Ding Yu's body, turning them into nutrients.

The bumps and sores on his skin started to fade, lighten, and wither.

"It worked!" Zhang Rongfang let out a sigh of relief. Any other side effects would have to be tested after Ding Yu woke up.

There was no rejection reaction, everything went smoothly.

This made Zhang Rongfang feel more like a legendary zombie, a Blood Race from the West.

Except for not fearing sunlight and being unable to control the blood-sucking impulse, in other aspects, he was very similar to the Blood Race!

For instance, the super strong physical qualities and super fast recovery speed.

And... developing descendants...

Zhang Rongfang had thought about what he would become after the flesh and blood were replenished.

But he didn't expect that what the replenished flesh and blood brought was such a peculiar ability.

Also, aside from the enhanced five senses and further improved physical qualities, there were no additional manifestations.

Out of curiosity about Ding Yu's current state, Zhang Rongfang stayed in the room, waiting for Ding Yu to wake up, instead of going elsewhere.

Time passed bit by bit.

About an hour later.

The setting sun slanted through the window.

Ding Yu slowly opened his eyes from the bed.

"I'm... alright!? My body is fine!?"

He felt an unprecedented comfort in his body, without any itching or pain, as if his body had been washed by pure spring water, clear, clean, and transparent.

"For now, yes." Zhang Rongfang replied.

"How do you feel now?"

"... Master... it feels amazing! Like the moment I used to feel after hard training when I entered a hot spring!" Ding Yu sat up from the bed, incredulously touching his chest.

Previously, he had all sorts of bumps and sores all over his body, but now... all those bumps had died, turning into a layer of grayish-white skin, which he tore off with his hands and tossed aside.

"Moreover... why do I feel like I..."

He clenched his fist, feeling a distinct change in his body.

He looked up at Zhang Rongfang again.

Inexplicably, there was a touch of admiration in his gaze towards Zhang Rongfang.

Like a long-returning scholar seeing a kind old father at home.

"Can you get up?" Zhang Rongfang looked at his gaze, already having a hunch.

"Yes!" Ding Yu flipped out of bed, wearing just a short-sleeved shirt and shorts, moving effortlessly a few times.

"Master... I feel like my body has become more powerful, what kind of medicine did you give me? It's so strong!?" Ding Yu was somewhat shocked.

He tried punching forward.

Whoosh!

The fist shadow flashed.

His punching speed was noticeably faster than before.

"What do you want to eat now?" Zhang Rongfang didn't reply but asked further.

"Uh... Spicy pig blood?" Ding Yu thought for a moment and answered.

Zhang Rongfang was left speechless. It seemed that Ding Yu was fine. Only time would tell if this method of saving someone had any drawbacks.

"Get up and come out, test your skills."

He turned to open the door and walked out.

Ding Yu followed closely, with light steps, feeling an unprecedented comfort and vitality in his body.

The two left the Treasure Harmony Pavilion and stopped at a martial arts field near Chen Zhaoqiao's place.

The martial arts field was as large as a football field, with a ground of compacted black soil, surrounded by three-meter-high walls, protecting against prying eyes.

The two stood facing each other.

"Come... attack me," Zhang Rongfang said.

He could feel that Ding Yu had undergone some changes, but needed to observe to know exactly what had changed.

"Master, be careful." Ding Yu immediately cupped his fists and stamped his foot on the ground.

Bang!

He shot out like a released arrow.

With a muffled sound.

In the blink of an eye.

Ding Yu flew past Zhang Rongfang's side, tripping himself with his own feet, rolled on the ground, hit his head hard against the ground, and rolled far away.

"I... cough cough... Why has my speed become so fast!?" He struggled to get up from the ground, with blood marks scratched on his face.

But those blood marks were fading and healing at a speed visible to the naked eye.

Seeing this, Zhang Rongfang finally understood.

Just now, Ding Yu's speed was far beyond what External Medicine Super Grade could achieve.

At the very least, he had reached the Inner Method stage, perhaps even faster.

It seems... it really was as he had guessed...
