(Revised)

She walked to the edge of the pool where the bowl was placed, picked up the bowl and filled it with water, turned and walked out of the room, heading towards the big tree.

After Song Jinqiao poured water on the tree roots, he took a few steps back and looked up at the tree. The tree had not changed much from before.

She was a little curious about what this big tree was, as it allowed the pagans to water it with water that was so full of power.

While she was thinking, a leaf suddenly fell slowly to the ground. She paused, and after realizing that there were no orcs around, she calmly put the leaf into her space, ready to study it carefully.

When she put the bowl back into the room, she collected some more water and put it in the space.

For the next few days, Song Jinqiao watered the tree and studied the water and leaves, but unfortunately, he didn't find anything.

That day, Song Jinqiao finished her routine watering and was about to return to her room to continue her research, but the arrival of the old female disrupted her thoughts.

"Has the tree lost any leaves recently?" the old female asked sharply.

Song Jinqiao was silent for a moment, somewhat unsure whether he had been discovered for taking leaves from the tree. However, he replied calmly with a serious expression, "I didn't see any leaves fall from the tree."

The old female's eyes flashed, and her fierce expression gradually turned into her usual frail look.

"You... follow me!" The old female still had that expressionless look on her face, and ordered Song Jinqiao in a commanding tone. After that, she turned and left without even looking at her.

Song Jinqiao obediently followed the old female as she walked along the corridor of the palace.

Suddenly, a man came over from the front. He was wearing a black robe and was extremely handsome. His expressionless face made him look extremely cold.

The old female saw the man standing aside and bowed her head respectfully and said, "Master."

Song Jinqiao also stood aside with her head down, but she didn't say anything and didn't look away.

The master seemed not to notice the two of them. He walked past them with a cold look, not even looking at them.

After the master left, Song Jinqiao looked at his back again. Because of this, she was scolded by the old female.

"What are you looking at!" The old female's eyes were sharp, and there was even a hint of murderous intent in them. "That orc is not someone you can look at. Go!"

Song Jinqiao remained silent, nodded slightly, and continued to follow the old female.

The old female brought her to a big tree, and at this time two leaves fell from the tree. Her eyes lit up, and she ran forward quickly, catching the leaves with her hands as if they were treasures.

Then she raised her hand and fiercely plucked two leaves from the tree. She returned to Song Jinqiao with the two leaves and commanded in a cold voice, "Follow me."

Song Jinqiao watched her holding the leaves excitedly, and was a little curious about what she was doing with the leaves, so he followed her silently.

The old female took Song Jinqiao with her and asked her to wait in a room. After giving her these instructions in a gloomy tone, she turned and left.

Looking at her back, Song Jinqiao's eyes flashed, and he let the system follow her quietly. The system turned into a ball of colorless and odorless mist, floated out of the space, and quietly followed the old female.

The old female walked around in the hall until she came to a wall, raised her hand, grasped a decorative handle on the wall, and turned it slightly.

"Boom..."

A rumbling sound was heard, and the wall slowly opened, revealing a downward staircase inside. The system was a little surprised.

It turns out there is a crypt underground!

Seeing that the door of the underground palace was about to close, the system flew in quickly. It knew that Song Jinqiao was not in a good position to watch Shui Jing, so it recorded everything.

The sea crystal lanterns on the wall illuminated the entire underground palace and also allowed the system to clearly see the many passages in the underground palace. These passages were all interconnected, and one could easily get lost if not careful.

The old female walked through many twists and turns, passed through numerous mechanisms, and finally came to a very spacious hall.

There was an inexplicable smell in the air, like the smell of blood and rust, in short, it was very unpleasant.

There are many contaminated crystals here, and what surprised the system the most is that there are four stone beds in this hall, with two females and two males lying on them.

Without exception, the four orcs were tightly bound to the stone bed with chains.

The old female glanced expressionlessly at the four orcs sleeping on the stone beds, picked out four contaminated crystals that she was satisfied with from the pile of contaminated crystals, and turned to walk to the bed of one of the males.

She placed a crystal on the male's chest, and instantly a strange array of gray light lit up around the stone bed. Then the old female followed suit and placed the three crystals in her hand on the other three orcs, and the same gray light lit up under the stone beds of those orcs.

This seems to be some kind of experiment.

The system speculated.

After doing this, the old female took out the four leaves from her clothes, and placed two leaves that fell naturally from the tree on the chest of a female and a male respectively, and two leaves that were picked directly from the tree on the other two females and one male.

After doing all this, a surprising scene happened.

But then a ball of gray mist gradually floated out from the polluted crystal, wrapping the leaves next to it. After a while, the gray-black mist gradually turned into gray-green.

Then the gray-green mist floated over the orcs for a while, gradually wrapping them completely.

The old female stood aside, watching the scene with a nervous look on her face. It was obvious that she took these matters very seriously.

As time goes by, the system's heart continues to rise and fall.

About five minutes later, the faces of the three orcs gradually became thinner, and they became skin and bones at a speed visible to the naked eye. Dark red blood seeped out of their skin, gradually gathering into a "river" and flowing along the stone bed to the ground.
