On the eighteenth level of the Great Void Grotto-Heaven, in a hidden mountain.
After Ye Xingchen arranged the array flags around him, he went into seclusion to cultivate.
Ever since he used the World Tree to suppress the Heavenly Demon remnant during the battle at the Heavenly Evil Valley, he had separated from Jun Changsheng and the others and entered seclusion here alone.
In his sea of consciousness, the World Tree was lush with leaves. Each leaf was crystal clear and dazzling.
A remnant soul was suppressed under the roots of the World Tree.
Most of the energy of the Heavenly Demon remnant had been absorbed by the World Tree. There were more than five hundred leaves on the World Tree.
The Heavenly Demon remnant was very faint at the moment. It was as if it would scatter like smoke if the wind blew.
"As long as you let me go, I will teach you the most powerful mind martial technique." The Heavenly Demon remnant was still tempting Ye Xingchen.
Heavenly Demons were the most unique lifeforms in the infinite worlds. They were strange and unpredictable. Heavenly Demons had no form. In other words, they were a stream of energy, a stream of information.
The sages of the Great Beginning Realm had speculated that Heavenly Demons might be a higher-level lifeform.
Regardless, Heavenly Demons were indeed powerful. A small Heavenly Demon could make a Nirvana or even Fragmentation Realm cultivator flustered. A Great Heavenly Demon could make a Mighty Cultivator's scalp tingle.
Ye Xingchen didn't doubt the Heavenly Demon's words. The Heavenly Demon Race's research on spiritual secret arts was far above that of the Human Race. In the myriad worlds, the only race that could stand shoulder to shoulder with the Heavenly Demons was the mysterious and unfathomable Divine Race.
Legend had it that the God Race was the descendant of the True God. The blood of the God Race flowed in their veins. Every member of the God Race was unbelievably powerful.
However, the God Race was very rare in the infinite worlds. They were scattered in different worlds. It was unknown if there was a God Race in the Great Beginning Realm.
Although Ye Xingchen was tempted, he did not believe the Heavenly Demon remnant at all.
After all, the Heavenly Demon Race was good at bewitching people and guiding the negative emotions of martial artists. They had all kinds of strange parasitic magical powers. If he was not careful, he could fall into their trap unknowingly.
Ye Xingchen had seen records of the Heavenly Demon Race in ancient books. The Heavenly Demon Race was a collective name. Under the Heavenly Demon Race were the Ghost Demon Race, Divine Demon Race, and of course, the most mysterious was the Heart Demon.
The Heart Demon was also a Heavenly Demon.
Heart Demons were also the most powerful and bizarre of all. Even members of the Heavenly Demon Clan rarely saw them.
Ye Xingchen did not know if this Heavenly Demon was an inner demon, so he would not give it a chance to take advantage of him.
He ignored the pleas of the Heavenly Demon Remnant Soul and continued to urge the World Tree to absorb the power of the Heavenly Demon Remnant Soul to strengthen the World Tree.
The World Tree flickered with light, its leaves sparkling and translucent. Some were like blood jade, some were verdant, some were sparkling blue, some were dark green, and some were golden.
At that moment, the Heavenly Dew that had originally dried up started to condense once again. It was slowly taking form.
Suddenly, a black fruit appeared on the World Tree, and a mysterious energy was emitted from the fruit.
"This is the World Tree's World Origin Fruit, condensed from the energy of the heavens. It has extraordinary uses." Ye Xingchen was excited.
He looked at the Heavenly Demon Remnant Soul that was about to dissipate and immediately understood that this World Origin Fruit had absorbed the power of the Heavenly Demon Remnant Soul to grow.
"I'm about to die, and I don't have any power left. I'm no danger to you."
The Heavenly Demon Remnant Soul's weak voice sounded. "I'm the Heavenly Demon King. I know many secrets of the Heavenly Demon Clan, as well as some of your Absolute Beginning Realm's secrets. I'm also proficient in all kinds of martial arts and mental secret techniques. As long as you spare me this time, I can tell you everything."
Ye Xingchen looked at the World Tree's World Origin Fruit and fell into deep thought. Suddenly, he felt a strange power wrapping around his soul.
"Hmph, you still won't give up." Ye Xingchen snorted coldly. His mind was like a blade, and he destroyed the special power with one slash.
At that moment, the Heavenly Demon Remnant Soul became transparent and almost invisible.
"I was wrong, I was wrong. I shouldn't have schemed against you." The Heavenly Demon Remnant Soul immediately admitted defeat. It really felt the danger of death.
It had been pretending before, but now it was really afraid.
Although the Heavenly Demon was strange and unpredictable, it had a limit to its life. It was not an undying being.
"Hand over a mental cultivation technique," Ye Xingchen said.
"Okay." The Heavenly Demon Remnant Soul did not waste time and sent a message. It was a mental cultivation technique.
Constellation Mind Technique!
This was a mental cultivation secret technique that allowed one to visualize the constellations.
There were twenty-eight constellations in the sky. They were divided into seven mansions of the Blue Dragon, seven mansions of the White Tiger, seven mansions of the Vermilion Bird, and seven mansions of the Black Tortoise.
By visualizing the twenty-eight constellations, one's mind could absorb starlight to strengthen itself. Finally, with a single thought, one could form the Four Divine Beasts.
Ye Xingchen studied it carefully and confirmed that the Heavenly Demon Remnant Soul had not tried it. It had a backup plan.
Ye Xingchen was not afraid even if it had a backup plan. The World Tree could destroy all mental thoughts. It was especially effective against the Heavenly Demon Clan.
Otherwise, when the Heavenly Demon Remnant Soul entered his consciousness, it would not have triggered the World Tree's suppression immediately.
Ye Xingchen had a bold guess. Perhaps the eternal World Tree that had stood tall in the universe had been cut down by a peerless expert of the Heavenly Demon Realm.
Ye Xingchen stopped thinking about it and focused on comprehending the Constellation Mind Technique.
Soon, his mind connected with the Stars in the Heavens. His mind entered the void and he could vaguely see the Four Divine Beasts formed from countless Stars.
The Four Divine Beasts were extremely powerful and even more ancient than the gods. They were the most ancient gods in the world.
Ye Xingchen's mind visualized the Four Divine Beasts and triggered the Constellation Force to descend.
The first to descend was the Azure Dragon. The Azure Dragon was in the East and was in charge of life.
Under the light of the Azure Dragon's Seven Constellations, Ye Xingchen felt his mind warm up. Before he knew it, he had broken into the second rank of the True Realm.
Next was the White Tiger's Seven Constellations. The White Tiger was in the West and was in charge of killing.
The next moment, Ye Xingchen's mental energy was filled with sharpness and turned into rays of silver light. His killing intent soared into the sky.
Fifteen minutes later, the White Tiger's Seven Constellations retreated and the Vermilion Bird's Seven Constellations shone down.
The Vermilion Bird was in the South and was in charge of fire. Ye Xingchen felt his mental energy was like a scarlet sun, filled with explosive power.
Finally, the Black Tortoise's Seven Constellations shone down. The Black Tortoise was in the North and was in charge of water. Ye Xingchen felt his mental energy was endless. Not only did it have the power to contain everything, it also had the power to heal.
Ye Xingchen's cultivation lasted for three days.
During these three days, he continuously guided the Constellation Force to help him refine his mental energy.
His mental energy had already reached the third rank of the True Realm.
"So much time has passed. It's time to go out and take a look." Ye Xingchen stood up, put away the array flags and walked out.
"To enter the nineteenth level, I need to pass the guardian's test. I wonder if anyone has passed it during this time."
From the ninth level to the tenth level, one needed to withstand a guardian with the strength of a young Sage for a hundred moves. From the eighteenth level to the nineteenth level, one also needed to withstand a hundred moves.
However, the previous guardian only used thirty percent of his strength. This time, he used fifty percent of his strength.
Ye Xingchen arrived at the center of the eighteenth level, under the Great Void Ancient Tree.
