Tens of thousands of jellyfish flowed into the tree hole. The tree hole was like a bottomless pit, and the light inside was getting brighter and brighter.
Han Sen could feel the presence inside the tree hole grow scarier and scarier. He stared into the tree hole, but the presence was too strong. Not even his dongxuan aura could penetrate it, so he couldn't see what was going on inside.
Xiang Yin didn't care about what was happening inside the tree hole. She was still sitting on the branch, swinging her feet. She said to Han Sen, "Do you want me to teach you how to play the xun?"
"Sure." Han Sen paused for a moment, and then he handed the xun to her.
This was a critical moment for Xiang Yin, and he didn't expect her to be so relaxed.
Xiang Yin took the bone xun and placed it next to her mouth. Her slender, jade-white fingers pressed on the holes. Her red lips parted slightly, and suddenly, a sound as quiet as bamboo came out of the bone xun.
Han Sen had never seen an instrument like this before. He thought the sound of the bone xun was low and sad. It was like a beautiful woman whispering sweet nothings in a quiet valley.
He could hear it clearly, but he couldn't, either. It was a deep and profound sound.
It was like the sound of a flute, but it was also different. Han Sen didn't know what it was, and he didn't know if it was the bone xun or if it was Xiang Yin's skill. He thought it was very moving, and it was easy to listen to. It was like a falling leaf in autumn, and it was very beautiful.
Xiang Yin raised her fingers, and many notes came out of the holes. They turned into Musical Note Fairies, and they danced around her. They made her look like a fairy. Even Han Sen was mesmerized by her beauty.
The creatures that were agitated because the Mother Tree was about to mature gradually quietened down after hearing the whistle. It was as if they were engrossed in the music and were no longer as agitated as before.
Fortunately, Han Sen had seen a lot of things, so he quickly recovered. He used his Dongxuan Aura to observe the energy flow of Xiang Yin's lifeforce from a close distance.
Xiang Yin was using her own energy flow to play the xun. If it were someone else, they wouldn't be able to produce such an effect.
When the Dongxuan Aura touched her, Xiang Yin could tell she was a berserk super creature with ten gene locks open. Han Sen's Dongxuan Aura, which had only opened five gene locks, couldn't fool her.
But Xiang Yin ignored the Dongxuan Aura. She didn't break it, either. She wanted to teach him how to play the xun, so she continued to play it.
Han Sen was pleasantly surprised. He didn't expect to be able to see through the energy flow of a super creature like that. He just wanted to use his dongxuan aura to get a better feel for her energy flow and how she played the xun.
But Xiang Yin didn't seem to be guarding against him, and he could see her energy flow as she played.
Xiang Yin's energy flow was amazing, and it was one of the most profound energy flows Han Sen had ever seen. Using his dongxuan aura to memorize it was difficult for Han Sen to do so.
After Xiang Yin finished her song, the underground was silent. The creatures all stood there, watching her as she perched atop a tree.
The light in the tree hole gradually dimmed, and all the jellyfish flowers disappeared. They should have all rushed into the tree hole. There was only a flickering candlelight in the tree hole, like the flame of an oil lamp.
Xiang Yin stroked the bone xun and gave it to Han Sen. She said, "This is as far as I can teach you. You need to practice and learn how to play a few simple songs."
"I will practice," Han Sen said, taking the xun.
It was a shame that Han Sen was interested in the strange sonic powers that the bone xun produced. He was not interested in the musical path.
Xiang Yin knew Han Sen didn't like her, but she wasn't mad. She smiled at Han Sen and said, "You can go now. My time is up."
After saying that, Xiang Yin stood up on the branch and walked towards the tree hole.
Han Sen didn't know what sort of power Xiang Yin would attract if she became a demi-god, so he didn't dare linger. He told her to be careful, and then he returned to Nvxiang and the Blue Dinosaur. He watched Xiang Yin walk into the tree hole with them.
Xiang Yin walked up to the tree hole and reached into it with her jade hands. She slowly pulled out something from the tree hole.
Han Sen saw it clearly. It was the light inside the tree hole. Xiang Yin held it in her hands, and it was like a water droplet. It didn't disperse, though. It was like a transparent jelly made of water.
Xiang Yin placed her mouth in front of the transparent jelly, and her red lips landed on it as if she was kissing it. The transparent jelly-like liquid was sucked into her stomach.
As Xiang Yin swallowed the Mother Earth Fruit, the fragrance on her body became stronger and stronger. It had already covered the fragrance of the Mother Earth Tree. It had even condensed into smoke that was visible to the naked eye. It floated out from Xiang Yin's body, making her look like a fairy in the clouds.
The aroma grew thicker and thicker. It was like a cloud of mist lingering in the underground space. It made the underground space look like a paradise. Fragrant clouds surrounded every corner.
Han Sen smelled the fragrance around him, and he felt refreshed. It was as if he had suddenly become a few years younger. He knew this fragrance was good stuff, so he took a few more deep breaths, wanting to inhale as much as he could.
All sorts of creatures could be seen in the clouds. They seemed to be inhaling the aroma, and they all looked as if they were enjoying it.
The fragrance of Xiang Yin's body turned into a cloud and rushed into the air. It was as if a curtain had been pulled open, and a very majestic stone door appeared in the air.
The stone door was simple and unadorned. There were no carvings or markings on it, but it had an indescribable sense of solemnity and holiness. It made one feel insignificant in front of it.
Aside from Xiang Yin, many creatures in the underground space knelt on the ground when they saw the stone door. Even super creatures like the Rock Rat King and the Blood Toad King were no exception.
"Is this the door of the Fourth God's Sanctuary?" Han Sen looked at the stone door with surprise.
When he was in the Second God's Sanctuary, he had seen creatures leveling up. The Holy Rhino and the Witch Spirit were taken away by the spirits of the sanctuaries.
Han Sen thought the stone door was a spirit from the Fourth God's Sanctuary that had come to take Xiang Yin, but it didn't open. It just floated in the air.
Xiang Yin rose into the air like a fairy. She flew towards the stone door with a determined look on her face.
