Inside the system space, Rainbow Maiden had already awakened. In this month of her birth, she had already completely understood her situation. The terrifying white serpent in front of her seemed to want to devour her, as if it wanted to break through to the Nascent Soul realm.

The system space quivered, and in the next moment, Rainbow Maiden appeared by the Heavenly Reflection Lake. Looking at her innocent appearance, Lin Xuan shook his head. She could only blame herself for being the Heavenly Spirit.

After a bit of self-improvement, he prepared to open his mouth and swallow Rainbow Maiden. However, before Lin Xuan could complete his self-improvement, it seemed that the Rainbow Maiden by the lake had made up her mind to save her life. Her body transformed into a seven-colored radiance, heading straight for Lin Xuan's head.

Lin Xuan furrowed his brows slightly. While her speed was fast, intercepting her was an effortless task. However, neither his brain nor the system gave him any warning. Looking into the innocent eyes of the Rainbow Maiden, it seemed she harbored no malice. She didn't even understood what malice was. In her eyes, there was probably only the desire to survive.

"What does this fellow want to do?"

Since there was no danger, Lin Xuan's curiosity was piqued. He didn't move and quietly waited to see what Rainbow Maiden wanted to do. He was confident that with his current strength, he could resist anything Rainbow Maiden might attempt. It was the absolute confidence bestowed by absolute power.

As if she knew what Lin Xuan was thinking, the Rainbow Maiden moved even faster, and in the blink of an eye, it plunged into Lin Xuan's mind. On the side, Lin Huaishu and Lin Xiong, who witnessed the entire process, were stunned. They continued with their tasks.

Even though they didn't know what Grand Ancestor wanted to do, it was clear that the Golden Core Rainbow Maiden couldn't harm him.

At this moment, inside Lin Xuan's mind, two figures were entangled.

"Mm!"

"Hmph!"

"Ah!"Lin Xuan made a mistake. The rainbow maiden did have a way to influence him. He couldn't have dreamt that when Rainbow Maiden entered his mental consciousness, she would fuse with his soul. Perhaps it was because of the karma from his past life, but Lin Xuan's soul didn't appear in the form of a white serpent, but rather in the human form of his previous life. The pleasure of merging souls far exceeded his imagination.

The moment their souls began to merge, it felt as though the entire world was drifting away from him. It was a sensation thousands of times more intense than physical desires. Only when the fusion of souls began did Lin Xuan react. This was the survival method of the Rainbow Maiden. This was why she was targeted!

Through dual cultivation with a cultivator, it could instantly help the cultivator break through to the Golden Core, or even guarantee the Third Revolution. Obviously, it was impossible for Lin Xuan's snake form to dual cultivate with the Rainbow Maiden. Therefore, the other party used a more extreme method.

Their souls fused together. This direct contact of souls was the most lethal. An unceasing stream of energy gushed out from Rainbow Maiden, nourishing Lin Xuan's soul. If physical dual cultivation could only help a peak Foundation Establishment cultivator break through to the Third Revolution of the Golden Core, then the power that could erupt from soul fusion would be a hundred times greater.

Moreover, because it was directly applied to the soul, it was absorbed completely, without any waste. For a cultivator to leap from the Foundation Establishment Realm to the Nascent Soul Realm, while it might be impossible for ordinary cultivators, the miraculous aspect of being the Heavenly Spirit came into play.

Of course, except for a few rare cases, this method was almost impossible. Unlike physical dual cultivation, soul fusion had to be mutually agreed upon. Otherwise, contact between souls would be the most dangerous. If there was resistance, the soul could easily be damaged. In that case, even if there were no benefits, the Dao could also be destroyed.

When Lin Xuan had thoroughly enjoyed himself and looked at Rainbow Maiden's rosy cheeks, he couldn't help but shake his head and sigh.

"This move is indeed a survival technique. It seems you know that I want to use you to break through to the Nascent Soul Realm, so you took this step. However, while this feedback might help an ordinary Ninth Revolution Golden Core cultivator break through to the Nascent Soul Realm, it is of no use to me.

"What I need is the essence of the Heaven and Earth within you, a power that can, at most, open a crack in my Great Dao Golden Core."

As if sensing Rainbow Maiden's thoughts, Lin Xuan's bloodline ability, Swallowing Heavens, suddenly began to operate on its own. Above Lin Xuan's soul, a special devouring force gradually appeared.

Visible to the naked eye, a continuous stream of light spots emerged from the depths of Rainbow Maiden's body and flowed into Lin Xuan's soul. They were continually devoured.

Lin Xuan's soul power began to skyrocket at an unimaginable speed. Both the strength and quantity of his soul seemed to erupt like a volcano."So this is the essence of heaven and earth?"

Lin Xuan, observing the scene, was filled with astonishment. Later, his gaze gradually lost focus. The pleasure of soul fusion and absorbing the essence of heaven and earth was something not even immortals could bear.

As Lin Xuan's soul swelled within his mental consciousness, the power of his Great Dao Golden Core in his dantian increased at an unimaginable speed. With the growth of power, it began attempting to break free from the constraints of the Great Dao Golden Core.

As time passed, cracks appeared on Lin Xuan's Dao Golden Core. His own aura began to surge rapidly.

In the Heavenly Reflection Lake, Lin Huaishu and Lin Xiong stared with wide eyes at their sleeping Grand Ancestor. His aura was particularly prominent at this moment, suppressing the entire Heavenly Reflection Lake. If not for the protective array set up by the Lin family, isolating this place…

…

At this moment, the Grand Ancestor's terrifying aura had already covered the entire Baolin Mountain Range.

Besides the increase in aura, Lin Xuan's original ten thousand-meter-tall body began to grow. Eleven thousand, twelve thousand, thirteen thousand… almost every stick of incense's time, Lin Xuan's body would expand by thousands of meters. His rate of growth could be described as terrifying.

"Is Grand Ancestor about to break through to the Nascent Soul Realm?"

Lin Huaishu realized excitedly. Lin Xuan's cultivation at the ninth refinement of the Golden Core was no secret to the entire Lin family. With the recent influx of resources from the past half month, if given some time to digest, it would be enough to nurture two or three Nascent Souls. So, Grand Ancestor's breakthrough was only natural.

"Lin Xiong, this is a command token for the Baolian Palace given by the Patriarch. You can control the formation of the Heavenly Reflection Lake and even the entire Baolin Mountain Range. Protect Grand Ancestor here well.

"From this moment on, no one is allowed to approach the Heavenly Reflection Lake. If they do, regardless of who it is, use the formation without mercy." Lin Huaishu took out a golden token from his pocket and handed it to Lin Xiong, his expression serious.

Lin Xiong was still in a daze. He looked at Lin Huaishu and said, "What about you, Brother Shu?"

"I will go outside to inform the Patriarch and gather all the cultivators from outside. Before Grand Ancestor breaks through to the Nascent Soul Realm, our Lin family will do everything we can to protect him." Lin Huaishu looked at Lin Xiong and said earnestly.

"The Patriarch instructed me to do this before leaving."

Seeing Lin Huaishu's solemn gaze, Lin Xiong nodded heavily. "Brother Shu, rest assured. With Lin Xiong and the surrounding formations, I won't let anyone approach the Sky Reflection Lake and Uncle."
