Chapter 391: Experiments And Direction (I)

Within Wuling City.

In an ordinary courtyard by the river outside the city, Lin Zheyu lay with his eyes closed inside a specially made bathtub. The bright moonlight fell upon his face, revealing the appearance of an ordinary middle-aged man. The wooden tub Lin Zheyu soaked in was custom-made and appeared slimmer and narrower than a normal bath barrel.

Once Lin Zheyu immersed himself inside, very little space remained. Cultivating the Primordial Wuji True Technique required a vast number of herbs, especially since they had not been refined into medicinal pills, making the quantity of herbs rather astonishing. When he used Origin Force to enhance himself, even when using water as a medium to absorb the medicinal properties through the mysterious energy produced by Origin Force, the range he could absorb was still limited.

The basins he normally used could not contain so many herbs, while a standard bathtub exceeded Lin Zheyu's absorption range. For this reason, he had this uniquely slender tub custom-made. Inside it were all the herbs required for fifteen years of cultivating the Primordial Wuji True Technique, along with one hundred sets of Blazing Flame Blood-Burning Powder herbs to serve as the energy needed to reshape his body during the Origin Force enhancement.

Whenever Blazing Flame Blood-Burning Powder could be used, Lin Zheyu would still prioritize it as the energy source for Origin Force enhancement. As for the three spirit stones and five bottles of spirit liquid, Lin Zheyu intended to save them for later use after advancing to the Force Transformation realm.

After advancing to the Force Transformation realm, the energy required for Origin Force enhancement would become far more astonishing. The energy density of Blazing Flame Blood-Burning Powder would no longer be sufficient for Lin Zheyu's needs. Only spirit stones or spirit liquid with higher energy density would suffice.

Inside the tub, various herbal powders were mixed into a thick paste. Vast mysterious energy swept up the medicinal properties within the tub and entered Lin Zheyu's physique. Under the transformation of this mysterious energy and immense medicinal force, Lin Zheyu's body was undergoing tremendous change. His muscles, tendons, and bones became increasingly firm and powerful, his muscle lines grew more refined, and every muscle of his was filled with explosive strength.

After a few breaths, Lin Zheyu slowly opened his eyes and let out a long breath of turbid air.

[Heaven Rewards the Diligent]

[Name: Lin Zheyu]

[Origin Force: 6]

[Skills: Tortoise Breath True Technique (Sixth Stage: 0%), Blood Burning Saber Technique (Third Stage: 100%), Sacred Evolution Spirit Nurturing Art (Second Stage: 0%), Primordial Wuji True Technique (Second Stage: 63%)]

"8 units of Origin Force have raised the Primordial Wuji True Technique to 63% of the second stage. The speed is much faster than expected. With about 5 more units, it should reach Perfection at the second stage," Lin Zheyu said with satisfaction as he looked at the data in his consciousness.

The Primordial Wuji True Technique consisted of five stages. The first stage mainly transformed one's original True Technique into the Primordial Wuji True Technique. The second stage marked the true beginning of cultivating it and belonged to the Marrow Refining realm. Its focus was on condensing the Primordial Body and comprehending the Primordial true intent. With his spirit and soul strengthened and freed from the influence of true intent, Lin Zheyu found it much easier to comprehend.

"Let's continue."

Lin Zheyu did not rest and instead prepared to raise the Primordial Wuji True Technique to Perfection at the second stage in one go, reaching the limit of what could be cultivated in the Marrow Refining realm.

With his spirit and soul strengthened, the amount of Origin Force he could endure each day had increased considerably. Enhancing by over 10 units of Origin Force was entirely manageable for him.

Use 5 units of Origin Force to cultivate the Primordial Wuji True Technique.

As the thought was conveyed, Lin Zheyu's spirit wavered, and he entered a familiar state.

"He's here!" By the riverside, several figures stealthily emerged from the forest.

"Have you checked the other party's background and strength?" a masked man asked in a low voice.

"He acts alone and likely has no background. The herbs he purchases are mostly for Marrow Refining realm cultivation. With so many Marrow Refining realm experts on our side, dealing with him alone will definitely not be a problem," the man said confidently.

After returning to Wuling City, although Lin Zheyu had altered his appearance and exercised great caution when purchasing herbs, the sheer quantity he bought still drew the attention of some watchful individuals. Moreover, the courtyard he rented lay in a remote area outside the city, where patrols rarely passed. This further tempted them to take the risk.

"Better safe than sorry. Ah Wang, Ah Biao, go ahead and scout first. Quietly release the Purple Anise Chestnut Fragrance Poison into the courtyard," the leader instructed.

Purple Anise Chestnut Fragrance Poison was a terrifying toxin. Even Force Transformation realm experts would be poisoned if they inhaled a large amount without noticing. However, Force Transformation realm martial artists could expel the toxin using true strength, and the process would take less than an incense stick's time. During the expulsion, however, their true strength circulation would still be affected.

Although this poison could affect Force Transformation realm martial artists, it was nearly impossible to poison them in practice. Their true strength constantly covered their bodies, preventing the toxin from penetrating. Purple Anise Chestnut Fragrance Poison was mainly used against powerful Marrow Refining realm martial artists.

"Alright!"

"Yes, Boss."

Two voices responded at the same time.

As soon as the words fell, two figures slipped silently from the forest, moving with astonishing speed. Under the moonlight, they became streaks of shadow and vanished without a sound, like ghosts. They reached the courtyard and quietly crouched by the wall to observe the situation inside.

"This courtyard is usually empty. He only comes here when he buys large quantities of herbs. I suspect he has some unknown secret," Ah Wang whispered with a grin.

"I also..." The other man was about to speak when his voice abruptly stopped.

A hand with a grip like an iron vice clamped onto his neck, crushing the bones instantly. Ah Wang heard nothing from his companion and sensed a faint sound behind him. He lunged forward in an attempt to flee, but it was already too late. In the darkness, a blade flashed like lightning, and his body was split in two, blood spraying several meters away.

"I need to move again," Lin Zheyu murmured as he looked at the two corpses on the ground.

His Perception Domain was no joke. Just after enhancing himself with Origin Force in the courtyard, Lin Zheyu detected the two approaching figures. This was not the first time such a thing had happened. There were always fools who found life too dull and set their sights on him, courting death. This time, the herbs he had purchased were both rare and numerous, attracting Marrow Refining realm martial artists.

Whoosh.

Lin Zheyu tapped lightly with his toes and vanished instantly. Soon, over a dozen screams echoed through the forest, but they lasted only seconds before stopping. The forest returned to silence, leaving only the rustle of leaves and the flow of the river.

Crack. Rustle.

Lin Zheyu slowly emerged from the forest, stepping on dry branches and leaves with soft sounds. Blood slid down the blade, reflecting a sinister crimson glow under the moonlight.

My blood qi has hardly increased, but my physique has improved greatly. I estimate my physical strength has risen by about 30%,

Lin Zheyu thought.

Boom!

In an instant, a sonic boom erupted in the air. Lin Zheyu vanished and shot forward hundreds of meters in the blink of an eye. Without using any blood qi, his physique alone allowed him to break the sound barrier and exceed supersonic speed.

"So powerful! I never expected the Primordial Wuji True Technique to enhance the physique so much," Lin Zheyu said in astonishment as he stopped.

It truly deserved its status as the Wuji Sect's top technique. This powerful true technique brought comprehensive improvements to Lin Zheyu's physique, including recovery, speed, defense, and strength. He felt his body becoming more perfect. This perfection did not stem merely from increased strength but from evolving toward a more ideal state after forming the Primordial Body.

If I encounter a yao martial artist of that level again, even without using the Blood Burning Saber Technique, I am confident I could exhaust him to death,

Lin Zheyu thought.

Yes, exhaust him rather than kill him outright. After Pei Xuan underwent yao transformation, his body evolved, and his bones became incredibly tough. Without using the Blood Burning Saber Technique, Lin Zheyu still could not break his defense, but he could exhaust him. After forming the Primordial Body, his body's capacity for containing blood qi had increased.

The blood qi within Lin Zheyu's body had reached an astonishing fivefold level! At the same time, his defense had greatly improved. In terms of physical defense alone, he was not much weaker than Pei Xuan after the yao transformation. With his powerful defense and immense blood qi reserves, he could exhaust Pei Xuan's energy before killing him.

[Heaven Rewards the Diligent]

[Name: Lin Zheyu]

[Origin Force: 1]

[Skills: Tortoise Breath True Technique (Sixth Stage: 0%), Blood Burning Saber Technique (Third Stage: 100%), Sacred Evolution Spirit Nurturing Art (Second Stage: 0%), Primordial Wuji True Technique (Third Stage: 0%)]

Next, I need to find more true techniques with thunder and fire attributes to strengthen the Yang nature of my true strength,

Lin Zheyu thought as he looked at the data in his consciousness.

With only 1 unit of Origin Force left, Lin Zheyu did not plan to use it to enhance the Sacred Evolution Spirit Nurturing Art. The second stage required true strength and was far more effective than the first stage. Using Origin Force on the first stage would be wasteful. After testing his strength, Lin Zheyu returned to the courtyard.

The herbal powder in the tub still retained some medicinal power, though not much. Lin Zheyu buried the residue along with the tub in a deep pit within the forest. After tidying up the courtyard, he left. Since this place had already been noticed, he did not intend to return to avoid unnecessary trouble.
