166: Chapter 166 Entrance to the Cultivation World

"It is daytime now; I cannot undergo the Lightning Tribulation here."

Thinking of this, Xiao Yuchen stepped into the Void Realm and arrived in the deep mountains. The thunderclouds in the sky kept him locked on, and he finally stopped deep within the mountains.

Rumble! Thunder rolled. Xiao Yuchen could feel that the Soul Transformation Stage Lightning Tribulation was much more powerful than the Nascent Soul Stage Lightning Tribulation. However, his lightning locking tower had also been upgraded to a Low Grade Divine Artifact, so there should be no problem absorbing these lightning bolts.

Seeing the dark clouds in the sky becoming increasingly dense, a thick silver dragon finally descended from the sky, striking Xiao Yuchen fiercely.

Xiao Yuchen was not afraid at all and circulated the Great Desolation Spirit Swallowing Technique to begin absorbing the power of the lightning. As the number of lightning bolts increased, Xiao Yuchen finally began to struggle to bear them. He had no choice but to bring out the lightning locking tower and collect all the remaining lightning bolts into it.

After the Lightning Tribulation, the dark clouds dissipated, and the five-colored aurora fell once again, shining upon Xiao Yuchen.

Although Xiao Yuchen was not injured, the five-colored aurora shining on him made him feel very comfortable.

When the five-colored aurora disappeared, Xiao Yuchen officially stepped into the threshold of the Soul Transformation Stage.

After stepping into the Soul Transformation Stage, Xiao Yuchen felt that the nine Nascent Souls within his body had grown much larger than before, and his strength was several times greater than it had been.

"Ding! Congratulations to the host for successfully breaking through to the Soul Transformation Stage. Rewards: Wood Spirit Stone, golden crow underworld fire, and three High Grade Jade Divine Pills have been placed in the System Inventory. Please check them, host."

The System's voice rang out again. Xiao Yuchen was very happy; he had always been satisfied with the rewards for cross-Rank Breakthroughs, so he hurriedly checked the item descriptions.

The Wood Spirit Stone was naturally used to awaken the Wood Spiritual Root. Although the Wood Spiritual Root could not compare to other Spiritual Roots in terms of combat power, the Wood attribute could increase recovery ability.

Of course, Xiao Yuchen possessed the Prehistoric Sacred Body, so his recovery ability was already very strong. He mainly liked using elemental power to increase his cultivation.

The golden crow underworld fire came from the sun's fire and was the twelfth-ranked Sacred Fire, which was slightly stronger than the Purple Heart Sacred Fire.

However, Xiao Yuchen did not care about strength or weakness. He only knew that once he refined the golden crow underworld fire, his fire seed would upgrade again, and his cultivation could be further improved.

As for the Jade Divine Pill, it could help Cultivators at the Soul Transformation Stage increase their cultivation. Because it was a High Grade, it guaranteed a 100% Breakthrough.

Just as Xiao Yuchen was checking the item descriptions, the Seal at his Sea of Consciousness suddenly shattered. It was the very Seal left behind by the Azure Dragon.

At the moment the Seal shattered, an image appeared in Xiao Yuchen's Sea of Consciousness.

It was a cave. The space inside the cave was not large, and powerful gale winds raged incessantly, leaving numerous cutting marks on the cave walls.

Although it was just an image, Xiao Yuchen could tell that it contained a high-level killing Formation. Moreover, for some reason, Xiao Yuchen always felt that the cave was somewhat familiar.

"Why is it so familiar? Could it be that I have seen that cave somewhere before?"

Xiao Yuchen fell into deep thought. Suddenly, his heart trembled, and he opened his mouth wide in shock.

"Isn't that the mysterious cave on the summit of Yunlong Mountain?"

The first time he arrived at the summit of Yunlong Mountain, Xiao Yuchen had seen that cave after compressing the spiritual mist there into spiritual liquid. At that time, he had wanted to enter and explore, but the inside of the cave made him feel danger, so he had given up.

At that time, Xiao Yuchen only had the cultivation of the tenth level of the Qi Refinement Stage, and the System had not yet gifted him the top-level Formation Master skill, so he had no idea that the danger actually came from a Formation.

"Having searched for so long, I never expected that the Teleportation Array to the Cultivation World would actually be in Jiangcheng, and that I had actually seen that cave."

Thinking of this, Xiao Yuchen thought of another possibility: his parents likely came to Earth from there years ago. Otherwise, how could they have appeared in Jiangcheng so coincidentally?

In other words, the Azure Dragon Clan, the Black Tortoise Clan, and the Cultivation World where his parents were, were very likely the same plane.

Thinking of this possibility, Xiao Yuchen was very excited. Perhaps he would soon be able to see his parents.

"What exactly is the Cultivation World like? Are the people in the Cultivation World all very powerful? No, I must try my best to improve my cultivation."

Thinking of this, Xiao Yuchen took the golden crow underworld fire out of the System Inventory and used the swallowing method of the third form of the Fire Control Technique. When blue light appeared on his right hand again, Xiao Yuchen grabbed the golden crow underworld fire in his hand.

Under the protection of the blue light, Xiao Yuchen could not feel the temperature of the flames. When the blue light completely enveloped the flames, Xiao Yuchen stuffed the golden crow underworld fire directly into his mouth.

With the experience of swallowing the Purple Heart Sacred Fire, Xiao Yuchen easily swallowed the golden crow underworld fire.

As soon as the golden crow underworld fire entered his Dantian, it was swallowed by the first Nascent Soul. The fire seed within the Nascent Soul grew again after swallowing the golden crow underworld fire, reaching the third Rank.

The Aura on Xiao Yuchen, as the main body, also climbed rapidly, breaking through the Early Stage directly to reach the Middle Stage, and then continued to climb, though it ultimately did not break through to the Late Stage.

Previously, after one of Xiao Yuchen's elemental seeds upgraded by one Rank, his cultivation would increase by two levels. However, upon reaching the Soul Transformation Stage, he could no longer increase by two levels at once.

However, Xiao Yuchen was not disappointed. He took out the lightning locking tower again. If he absorbed all the lightning inside, it would definitely allow the Arc Seed to upgrade to the third Rank.

"It seems the System has become numb again; it doesn't want to continue giving me rewards."

Since there were no more upgrade rewards, Xiao Yuchen did not wait any longer and released the power of the lightning intermittently.

Several hours later, Xiao Yuchen had absorbed nearly a hundred lightning bolts, finally upgrading the Arc Seed to the third Rank, and Xiao Yuchen's strength had reached the Great Perfection of the Soul Formation Stage from the Middle Stage of the Soul Transformation Stage.

Feeling the power of his body, Xiao Yuchen nodded with satisfaction. Although he was only at the Great Perfection of the Soul Formation Stage, he possessed nine Nascent Souls and three Spiritual Roots, so even if he faced someone at the Great Perfection of the Void Refinement Stage, he should still have the power to fight.

"Ding! Congratulations to the host for reaching the Great Perfection of the Soul Formation Stage. Rewards: three High Grade Chongxu Pills have been placed in the System Inventory. Please check them, host."

"Could it be that I leveled up too quickly? The System only gave one type of reward."

Although he complained, he had no choice. He refined the Wood Spirit Stone and successfully awakened the Wood Spiritual Root. At the same time, a leaf-shaped wood seed appeared within Xiao Yuchen's Dantian and was swallowed by the fourth Nascent Soul.

"Another Spiritual Root awakened. At this rate, I should be able to collect the attributes needed for the eight Nascent Souls very soon."

Although Xiao Yuchen had improved by more than one Rank this time, there was no feeling of instability in the Spiritual Qi within his body, because this increase in strength was mainly due to the upgrading of the elemental seeds and had nothing to do with Spiritual Qi.

After the improvement was complete, Xiao Yuchen arrived at the Yangtze River Nuclear Power Plant again. Besides the newly awakened Wood Spiritual Root, his fire seed had now reached the third Rank, the lightning seed had reached the third Rank, but the water seed was still only at the first Rank.

Once he went to the Cultivation World, he would not be able to encounter places like nuclear power plants, so he could not let this opportunity pass; he had to at least upgrade the water seed to the second Rank.

However, he was now at the Great Perfection of the Soul Formation Stage. He did not know if upgrading the water seed to the second Rank would cause him to break through to the Void Refinement Stage.
