Apocalypse: Become stronger by absorbing flames at the start; my name is the Flame Emperor.

Despite feeling exhausted and sore, Lin Yu quickly poured three large jars of demonic beast blood into the bathtub.

The next moment, he took off all his clothes and soaked in the water.

Ignoring the viscosity of the blood, he immediately began practicing the breathing technique.

First, exhaust your physical strength through various means until you are depleted, bringing your body to a state of extreme weakness, like a hungry child eager to absorb power. Then, bathe in the blood of a beast containing immense energy and absorb its power through breathing techniques to temper your body.

This is the method of body refinement.

For an instant.

As the breathing technique was activated, all of Lin Yu's internal organs, meridians, and blood vessels vibrated in a peculiar and inexplicable rhythm, producing a rumbling sound within his body.

Instantly, the beast blood in the wooden barrel began to boil violently.

A burst of radiant light rose up; it was the terrifying energy contained in his blood, drawn by the breathing technique, surging wildly towards Lin Yu, flowing into his body through every pore.

These energies do not wander aimlessly, but rather, following the rhythm of the breathing method, they enter the first acupoint along a specific route.

"Boom!"

The first blood acupoint was like a black hole, swallowing and absorbing water like a whale, frantically devouring and refining this energy.

In just a few seconds, the first blood acupoint lit up, emitting a white light. When the light reached its peak, it seemed to have reached saturation and stopped absorbing energy.

Instantly, the energy absorbed by the breathing technique flowed rapidly towards the second blood vessel...

Begin the tempering process!

In less than an hour, all 670 ordinary blood vessels and twelve meridians in Lin Yu's body were tempered, emitting a white light.

Lin Yu knew that this was the second stage of the five realms of physical strength: the extraordinary appearance.

Of the five realms, the Transcendent Realm only cultivates the twelve meridians and 670 ordinary blood orifices. The Golden Body Realm requires tempering all 206 bones, flesh, and skin. The Dragon Body Realm, in addition to these, requires tempering the three most difficult parts: the dantian, the heart, and the brain, achieving a state of full-body resonance.

The invincible body is even more difficult to obtain.

Besides these, one also needs to cultivate the eight extraordinary meridians and 50 acupoints hidden throughout the body; this part is the most difficult.

It is said that the eight extraordinary meridians and acupoints contain the body's hidden spiritual power, and their importance is second only to the dantian.

"Next comes the entire skeleton, flesh, and skin."

A glint flashed in Lin Yu's eyes, and he focused on refining his skills once again.

With each breath, the breathing technique caused a resonance throughout his body, both internally and externally. The energy within his beast blood surged like a torrent through his meridians, flowing through every orifice and merging into his skull.

Time flew by, and another half hour passed. All 206 bones, flesh, and skin in the body had been thoroughly processed.

Lin Yu's whole body trembled, his meridians, acupoints, and bones glowed and resonated together, causing the white mist in his dantian to surge. The human spirit within it vibrated and fed back a mysterious power that surged into his heart and brain.

They also intensively refined these two very important aspects.

"Knock knock!"

"Knock knock—"

As time went on, the heartbeat grew stronger and more powerful, like the vibration of a large drum.

A moment later, a loud "boom" resounded from within him, as if everything had been perfectly accomplished. Without the slightest difficulty, everything within him had been tempered to its limit, emitting a thunderous sound.

First-tier Dragon Body!

It’s done!

At this moment, apart from the last eight extraordinary meridians and the 50 hidden acupoints, everything else on his body had been refined to the first level, reaching the true first-level Dragon Body Realm.

If one is cultivating an advanced technique, one can use the advanced breathing technique to connect all of these things at this moment, forming a first-order Great Circulation, and directly break into the second-order Dragon Body Realm.

However, this is not what Lin Yu wanted.

His goal is to achieve the ultimate physical body, and he aims to reach the pinnacle of physical strength at each stage, ultimately reaching the Overlord Body Realm.

and so--

Next, we need to cultivate the eight extraordinary meridians and 50 extraordinary acupoints.

"continue!"

Lin Yu's eyes flashed with a sharp light.

He could sense that the beast blood in the large wooden barrel contained a great deal of powerful energy.

Before they knew it, another two hours had passed, but Lin Yu's body remained completely still.

The next moment, he suddenly opened his eyes.

"What's going on? It still feels like something's missing."

Lin Yu looked at the beast blood in the bucket; it was completely devoid of energy. His physique was still at the first-tier Dragon Body Realm. He felt he was very close to achieving the Overlord Body Realm, but something was missing, preventing him from truly taking that step.

Even though all his orifices, bones, twelve meridians, eight extraordinary meridians, heart, and brain had reached the limit of the first tier, he was still a little short of breaking through to the Overlord Body.

"Is even a first-tier Invincible Body this difficult?" Lin Yu frowned.

This was only the first level, which was quite unexpected.

Suddenly.

He was thinking of something.

"Could it be—"

"Is the quality of this ordinary beast blood too low to forge a superhuman body?"

Lin Yu considered this possibility.

The next moment, he selected a large jar of blood from his spatial ring that looked different from ordinary beast blood. The energy emanating from it was significantly stronger than that in the bathtub.

"You're the one!"

Flames surged from Lin Yu's body, and with his powerful control over the flames, he directly evaporated the beast blood in the bathtub, replacing it with a bloodline and a higher rank.

"hiss--"

As soon as he soaked in the water, he felt a sharp pain on his skin.

"As expected, the blood of ordinary beasts and the blood of those with powerful bloodlines are ultimately different."

Lin Yu circulated his breathing technique, frantically absorbing the powerful energy within his bloodline.

He planned to use this higher-grade beast blood to re-temper his entire body and everything else.

For an instant.

A surge of energy rushed into the body, heading straight for the first acupoint. The blood in the acupoint, which had previously become saturated and stopped absorbing energy, began to circulate again, consuming energy.

"Advanced bloodline, it really works."

Lin Yu was overjoyed and began absorbing the nutrients frantically once again.

However, according to Fifth Jade Tree, while the Overlord Body is extremely difficult to cultivate, it's manageable up to the fifth rank; many prodigies can achieve it by investing time. After the fifth rank, however, the Overlord Body becomes incredibly difficult to cultivate.

It's like an insurmountable chasm, impossible to cross.

It's only at the first level of the Overlord Body, which is relatively the simplest.

One night passed.

Inside the room, Lin Yu was still soaking in the bathtub with his eyes closed.

Suddenly, a muffled boom came from his body, as if a river dam had been breached, and his physical strength vibrated and thunder roared.

"Finally, we succeeded!"
