...

He spent an entire day wandering around the sect until he was sure enough time had passed. Under the cover of night, he sneaked back to the corpse cave. Only after confirming there was no more smoke did he approach the reservoir.

The first thing he saw was that the smoke had indeed completely vanished. The redness in the water had somewhat faded, and red hair could be seen on the corpse's head. It was truly a terrifying sight, making the corpse appear even more murderous than before.

"Red hair?" With eyes wide open, he walked closer to the corpse. Suddenly, he felt like he wasn't alone. At the same time, the corpse's eyes opened, red as blood. There was no life in those eyes; they were cold, almost as if death itself was staring at him. Emitting a strong, cold aura, the corpse began to rise from the water.

With his scalp tingling, Yan Xiaobao braced himself and pulled out the jade sliding plate used to control corpses. After pressing his finger down on it, the zombie slowly moved.

After confirming it indeed did not move, he approached again to inspect the red hair closely. He said, frowning, "Xu Xiaoshan talked about white-haired and black-haired zombies. He didn't mention red hair. Does red hair count?"

Feeling a bit of a headache, he gritted his teeth.

"Ah, never mind. My potion formula clearly has issues. A few changes will surely turn this zombie's hair white!" Sitting cross-legged, he began to think this problem through thoroughly. Days later, he looked tired but slapped his thigh excitedly.

"It must be a problem with the water in the tank. The water changed color because the zombie absorbed the red!" The more he thought about it, the more it made sense. Without hesitation, he began concocting.

This time, he altered the formula, adding quite a few herbal plants. This time, he not only created medicinal incense but also produced a medicinal balm. Days later, he eagerly and expectantly threw the pill into the Blood Pool.

Once the pill entered the reservoir, it sank into the water. Moments later, the water began to bubble and churn, huge bubbles rising everywhere. With that, Yan Xiaobao tossed the incense that fell on the red-haired zombie.

This time, he did not leave, although he did indeed make some backups. Smoke filled the reservoir, and a trickling sound started to emanate from within. Then an inhuman howl echoed, sounding almost as if it came from an evil ghost or vile demon's mouth.

Several hours later, the smoke began to clear, and Yan Xiaobao glanced, trying to see the reservoir.

"Turn white hair! Come on, change! Change!"

Just as he muttered this, the smoke dissipated, and he hurried to the edge of the reservoir. When he saw the zombie, a blank expression appeared in his eyes.

"Violet hair?"

The zombie in the reservoir no longer had red hair but violet. Its murderous aura was even stronger, and most of the water in the reservoir had been depleted. Moments later, more blood-colored water rushed in, filling the reservoir.

Most shocking of all, the violet hair was three inches long, much longer than the red hair. Furthermore, the zombie's fingers now bore sharp claws...

"What is this thing?" Yan Xiaobao muttered, his eyes wide open. The zombie definitely looked more impressive, so he asked the imposter Nightcrypt. However, the imposter Nightcrypt had never heard of any zombies like this.

He hesitated for a moment, even considering asking Xu Xiaoshan to take a look. But then he thought of the mysterious pills that frequently appear when he concocts his medicines, and his expression flickered.

"Could this have something to do with the incense?" He thought about all the bizarre creatures he relaxed in the Spiritual Flow Sect, then shuddered.

"I can definitely turn the hair white!" Taking a deep breath, he gritted his teeth and began concocting.

Yan Xiaobao continued to produce incense after incense. The zombie's hair changed from violet to pink, then from pink to orange. Once, it even turned blue. But never white. Moreover, with each transformation, the hair grew longer and longer. When it turned blue, it was one-third of a meter long... Yan Xiaobao continued to produce incense after incense.

Meanwhile, the zombie's murderous aura grew stronger, and its claws became sharper. Two dangerous-looking fangs appeared in its mouth, and its skin and hair changed color together. The water in the tank drained time and time again, naturally refilling each time. Meanwhile, the zombie's murderous aura grew stronger, and its claws became sharper.

Six months passed, and Yan Xiaobao stood at the edge of the reservoir. He had stared at the zombie many times, to the point where he was starting to go crazy.

"I refuse to believe I'll fail!"

Yan Xiaobao was truly furious. He stood there face to face with the zombie, filled with frustration that it wouldn't turn white.

Turning around, he began tossing herbal plants into the pill furnace, including special Blood Stream Sect plants. He altered the pill formula again, and began to insanely devote himself to concocting.
