For powerful true strength to circulate smoothly through all the body's meridians, it was necessary to use true strength to reopen and expand the meridians. The process of opening the meridians with true strength was also the process of allowing the body's meridians to adapt to true strength.

True strength energy condensed into threads as fine as silkworm silk and rapidly circulated through the meridians, breaking through blockages and carving out powerful channels suitable for the flow of true strength. The hissing sounds continued as useless impurities clogging the meridians were blasted apart by the powerful true strength, turning into foul residues that were expelled from the body.

The process of opening the meridians produced terrifying pain and consumed enormous amounts of true strength. Large quantities of true strength were expended during the process, and the meridians themselves suffered damage under the force of the powerful energy.

However, under the effect of the mysterious energy, vast amounts of essence, qi, and spirit energy were rapidly converted into true strength to replenish the loss. A portion of the immense spirit liquid energy merged into the meridians, quickly repairing the damage caused during the meridian expansion.

After several breaths, Lin Zheyu slowly opened his eyes. The moment they opened, they were filled with bloodshot veins. The pain produced by advancing into the Force Transformation realm was stronger than he had expected, but it was still within a tolerable range. Previously, when he used Origin Force to cultivate body-refining techniques and the modified method of condensing blood qi, the pain he endured had far surpassed what he experienced now. His spirit and will had long been tempered to a terrifying degree.

"I've finally advanced to the Force Transformation realm. I never imagined that converting all forty-two true intents into true strength would be this terrifyingly difficult!" Lin Zheyu could not help but say.

Even after using 10 units of Origin Force, he still had not fully opened all his meridians to form a complete Great Circulation. Only when the meridians were fully opened, and true strength energy circulated through them according to the technique's route, forming a Great Circulation, could it truly be considered advancing into the Force Transformation realm.

At that point, the true strength energy moving along the Great Circulation would naturally absorb essence, qi, and spirit as well as true intent energy and integrate them within itself. Several different energies would be rapidly converted into true strength energy as they circulated with the technique. When that happened, Lin Zheyu would no longer need to painstakingly fuse different energies himself to condense true strength.

Lin Zheyu did not immediately begin the second round of improvement. Advancing into the Force Transformation realm had been far more difficult than he expected, leaving a considerable drain on his spirit and will. He needed a moment to recover.

Taking advantage of this pause, he observed the changes occurring around him. In his perception, the Baleful Yin force energy within the forest had increased to an astonishing level, and the roars of demon puppets coming from all directions were growing denser. The terrifying pressure pouring down made Lin Zheyu feel an immense sense of oppression.

What's going on? This pressure has grown stronger again! Lin Zheyu felt puzzled.

Before he used Origin Force to improve himself, the demon god pressure had been neutralized by the vast pressure emanating from Wuling City, reducing it to an extremely faint level. Now, however, the demon god pressure had grown stronger again. Although it was not as overwhelming as at the beginning, it had reached a level that even Marrow Refining realm martial artists would find somewhat difficult to endure.

The increasingly dense Baleful Yin force within the forest also made Lin Zheyu feel extremely uncomfortable. He possessed the aptitude for immortal cultivation as well. Although his aptitude was quite ordinary, his body could still naturally communicate with heaven and earth, albeit slowly.

When the concentration of Baleful Yin force was low, the sensation was not very strong. Now that the concentration had increased, he could feel that sinister energy constantly flowing into his body. Lin Zheyu took a deep breath and felt as though he could inhale large amounts of Baleful Yin force.

The concentration of Baleful Yin force in the forest has increased greatly... But this is also beneficial for me. Even someone with ordinary aptitude like me feels strong discomfort. Those who were chosen by the Directorate of Celestial Observation as disciples all possess terrifying natural talent. The effect on them within this forest will be even more severe.

He would not naively believe that after erasing that energy mark, the other party would no longer be able to find him. Even yao martial artists possessed items like the Ink Jade Disk. As a mysterious immortal cultivator, that young man might very well possess tracking dharma artifacts even more miraculous than the Ink Jade Disk.

Lin Zheyu knew very little about immortal cultivators. He had no idea what level of strength the person targeting him possessed or what mysterious methods he might have. The increase in Baleful Yin force concentration gave Lin Zheyu a slightly higher chance of defeating him. This was truly an unexpected piece of good fortune.

Lin Zheyu did not dare delay for too long. After taking several deep breaths, he closed his eyes again and began the second round of improvement.

Use 10 units of Origin Force to cultivate the Primordial Wuji True Technique.

The moment the thought appeared, Lin Zheyu's spirit once again plunged into endless cultivation. Mysterious energy surged out, sweeping spirit liquid energy into his body and condensing droplet after droplet of true strength, joining the process of opening the meridians.

Endless streams of true strength followed one after another, continuously impacting the meridians. The meridians were damaged again and again, yet under the effect of mysterious energy, they rapidly recovered and became stronger, able to withstand the circulation of true strength.

Soon, under the relentless impact of true strength, the meridians required by the Primordial Wuji True Technique were completely opened. True strength flowed along the technique's route within the meridians and completed its first full circulation.

In that instant, Lin Zheyu's body trembled violently. The circulating true strength formed an independent energy system that actively and continuously absorbed essence, qi, and spirit energy. The tight furrow on his brow relaxed considerably. However, this was only the beginning. The newly opened meridians were merely like small streams. As the true strength energy continued to grow stronger, the meridians would become wider and wider, able to carry even greater flows of true strength.

After completing the circulation, the speed of true strength surged wildly, like a horse that had broken free of its reins. Under this frenzied circulation, endless streams of essence, qi, and spirit energy, as well as true intent energy, merged into it, causing the true strength to grow rapidly. The total amount of true strength was closely tied to the physique's strength, the strength of blood qi, and the body's capacity.

Whether it was physical strength, blood qi strength, or capacity, Lin Zheyu far surpassed other martial artists. The amount of true strength energy his body could contain had reached an astonishing level.

After several breaths, Lin Zheyu slowly exhaled a long, turbid breath. His brows knitted deeply as a faint dizziness arose in his mind. He quickly took out the jade bottle containing Origin Stabilizing Pills and poured all three pills from the bottle into his mouth.

"That was pushing it too far. Fortunately, it only slightly overstrained my spirit and isn't too serious."

Lin Zheyu let out a long breath and could not help raising a hand to gently rub his temples. Although this improvement had overdrawn some of his spirit, an excited smile appeared on his face. He had finally advanced to the Force Transformation realm!

[Heaven Rewards the Diligent]

[Name: Lin Zheyu]

[Origin Force: 55]

[Skills: Sacred Evolution Spirit Nurturing Art (Second Stage: 0%), Primordial Wuji True Technique (Third Stage: 38%)]

Lin Zheyu looked at the data within his consciousness. He still had 55 units of Origin Force remaining. Unfortunately, with his current spirit condition, it was already difficult for him to continue improving with Origin Force. He would need to rest for at least half a day.

The progress has only reached 38%... To reach Perfection of the third stage, I'll need at least around 33 more units of Origin Force. There's still quite a distance from the peak of the Force Transformation realm. Much of that 38% progress was spent condensing true strength, opening the meridians, and forming the circulation. Once I truly reach the peak of the Force Transformation realm, the depth of my true strength will reach an astonishing level.

The foundation Lin Zheyu had laid before was terrifying. Not only was the strength of his true strength terrifying, but even the limit of how much true strength he could contain far surpassed that of ordinary martial artists.

Lin Zheyu closed his eyes and activated his inner vision, carefully observing the flow of true strength energy within his body. After the improvement from 20 units of cultivation, the true strength energy inside him had already reached a considerable scale. The gray true strength flowed rapidly through his meridians, constantly absorbing essence, qi, and spirit energy and growing stronger.

Lin Zheyu discovered that he could freely control the true strength within his body. After his true strength fused with his true intent, it formed a close connection with his spirit and will. With a single thought from him, the circulation speed of true strength immediately surged.

My true strength is actually gray. Perhaps it's primordial true strength... But isn't true strength supposed to be in a gaseous state...?

Lin Zheyu observed the true strength within his body with surprise. With a movement of his thoughts, true strength energy surged out and condensed into a small gray sphere of energy in his palm.

It really is different from Senior Sister Wenzi's true strength. My senior brothers and sisters have true strength that exists in a gaseous form. Even if their true strength is extremely dense, it is still only a thicker, more concentrated gas. Mine, however, has directly turned into liquid.

Lin Zheyu was very satisfied with the transformation of his true strength.

This meant that the essence of his true strength energy far surpassed that of ordinary Force Transformation realm martial artists. No. After condensing into a liquid form of powerful energy, it had already undergone a qualitative leap beyond true strength. Its essence had transformed, making the name true strength no longer suitable. Lin Zheyu felt that calling it true origin would be more appropriate.

From now on, I'll call this energy true origin. I wonder whether my true origin is stronger or weaker than the demon essence of the yaos and demons.

Why had he condensed so many true intents? It was precisely to restrain the demon essence of yaos and demons.

I'll first test whether the energy barrier can block the erosion of Baleful Yin force.

With a movement of his thoughts, a gray energy barrier appeared around him. Under his control, the barrier rapidly expanded, forming a protective radius of five meters around him.

Five meters was the limit of his energy barrier. One had to know that even a powerful Grandmaster-level martial artist in the realm of martial arts, like Huang Baizhong, known for his immense true strength, could only extend his energy barrier to less than two meters beyond his body. Lin Zheyu's five meters was therefore extremely exaggerated.

This is stronger than I expected. The erosion of the Baleful Yin force against the energy barrier has reached roughly a 56-to-1 ratio.

In the ratio of 56-to-1, the fifty-six referred to the Baleful Yin force, while the one referred to his true origin energy.
