Xuantian Immortal Cultivation Record

"Master, after Zhang San refined this evil soul, he felt a great power filling his body and may encounter a lightning tribulation at any time!" Zhang San's divine sense came, filled with excitement, trepidation, and anticipation.

Zhang Yuanjing was slightly startled and quickly asked, "Are you about to break through now?"

Zhang San replied, "Reporting to Master, that is not the case. Zhang San feels that a trigger is still needed. Once that trigger appears, Zhang San will immediately break through and undergo the lightning tribulation."

"Do you know what the trigger is?"

"Zhang San does not know. However, Zhang San feels that there is actually no bottleneck to the level of a magical treasure. It is as if I have already reached that realm. The reason why a trigger is needed may be due to the special nature of the artifact spirit, which requires a certain scene or experience to trigger the lightning tribulation, thereby tearing apart that invisible barrier and truly standing in a new realm." Zhang San pondered for a long time before sending back a thought.

Zhang Yuanjing's mind raced. He had never heard that artifact spirits needed such a requirement to advance. This may be related to the Refining Sun Umbrella's artifact spirit experiencing annihilation and rebirth, and even to his intervention in nurturing it.

Generally speaking, just like cultivators advancing to the God Transformation stage, the Refining Sun Umbrella should also have its own special requirements for breaking through from a Xiantian spiritual treasure to a magical treasure level, as long as it does not require a huge amount of heaven and earth spiritual energy like cultivators.

With a wave of his hand, he retrieved the Refining Sun Umbrella. Following his power, the umbrella shrank to its original size.

Zhang Yuanjing pointed to the spine lying in the mud like an earth dragon and asked Zhang San, "Are there any evil souls or remnant souls in this spine?"

Zhang San released a faint light, enveloping a section of the spine, and replied after a moment, "Master, there is only a peculiar power in this spine, but there are no evil objects such as remnant souls."

Zhang Yuanjing said, "The spine is very long, so continue to explore towards the skull."

Holding the Refining Sun Umbrella, he walked eastward, with the dark light following him. Lu and Luo followed closely behind.

Before long, the three arrived at the skull.

This skull was extremely large, measuring a hundred zhang in size, but many parts were missing. It had an almost transparent silver-gray color, as if it were formed from the dust of stars. The shape of the skull was peculiar, resembling both a fish and a beast, with high cheekbones and deep eye sockets like black holes, as if they could devour everything.

The brow bone was covered with intricate patterns, like star chart trajectories or some kind of ancient runes, shimmering faintly under the flow of the deep water.

The mandible was slightly open, revealing sharp rows of teeth, each tooth as sharp as a meteorite fragment, emitting a cold aura.

Zhang San enveloped the skull with a dark light, and the patterns began to twist, as if trying to break free. However, as the scorching sun rose, these patterns turned into wisps of blood, which quickly turned into light smoke under the light of the flames and disappeared into the swamp water.

"Crack!"

The skull cracked from the brow bone, with more than a dozen thick cracks extending in all directions. With a "boom", the entire skull collapsed, turning into a pile of broken bones.

"Reporting to Master, there was still a wisp of evil soul hidden in the skull, which Zhang San has completely refined."

Zhang Yuanjing praised him, put the Refining Sun Umbrella into his Sumeru ring, then walked closer to the pile of broken bones and sent out a surge of Thick Earth power, striking a mandible.

The mandible trembled twice, without the slightest damage.

Zhang Yuanjing's eyes lit up. He reached out and grabbed the mandible, pouring in mana and repeatedly squeezing it. After several times, the mandible was intact. Its hardness was the same as the bones of the alien beasts in the Profound Origin Secret Realm and the Hengduan Mountains.

"Yuanjing, is this usable?" Lu Tianying asked.

"Of course," Zhang Yuanjing said with a smile. "Back then, I only used a piece of this kind of alien beast's broken bone to exchange for a Nourishing Spirit Pill from the Profound Elixir Hall, but the actual value of this thing is much higher than the Nourishing Spirit Pill."

Lu Tianying's eyes lit up and said, "Then I'll take some too."

He waved his hand and released a surge of mana, picking up more than a dozen bone fragments and putting them into his storage bracelet.

Zhang Yuanjing turned his head to look at Luo Yuanhao: "Fellow Daoist Luo, you can also take some."

Luo Yuanhao shook his head: "Luo will not take it. In the future, I will have to trouble Fellow Daoist Zhang to help with something. If it can be done, these bones will be indispensable."

Zhang Yuanjing smiled lightly and said nothing more. He took out several storage bracelets, released his mana to guide them, and collected all the larger skull fragments.

Afterward, the three returned to the middle section of the spine.

Zhang Yuanjing took out the bone fragment and immediately felt the urge to try again.

He really didn't know what the consequences of following it would be. However, since obtaining this bone fragment, it had been almost useless except for the coincidental conditions to use it to strike enemies who approached. He was already a Nascent Soul cultivator, and in the future, there would be few opportunities for close combat. This bone fragment was like a chicken rib, which was a pity. Now that he had encountered an opportunity suitable for this thing, he had to take a risk and try.

With this thought in mind, he tossed the bone fragment into the air. The bone fragment generated a force of its own and fell into the gap in the spine, fitting perfectly into it.

The bottom of the abyss was as dark as ink, and the surroundings were so quiet that only the sound of water flowed. The bone fragment seemed to merge into the spine, completely silent.

Time passed by. The divine senses of the three people were focused on the bone fragment, and they gradually felt a strange power flowing with the water.

A faint light suddenly flashed. The exposed end of the bone fragment seemed to have stardust gathering, and the light gradually brightened.

"Star power?"

Zhang Yuanjing's mind raced, and he felt a little relieved. The strange power of the void alien beast must come from an existence in the void, which is likely to be some kind of star. Such great power also belongs to pure power and has no evil in it.

"Yuanjing, look, the spine is glowing!" Lu Tianying suddenly exclaimed.

Zhang Yuanjing and Luo Yuanhao looked to both sides. Sure enough, the mountain-like spine emitted a faint light from far to near, like a band of light, swaying hazily in the deep water, like a dream.

Zhang Yuanjing's divine sense was still focused on the bone fragment. Even from the outside, he could feel that a great power was constantly gathering within the bone, and the bone fragment seemed to be developing spirituality.

With a thought in his mind, he strode closer, stopping three feet away from the bone fragment.

The bone fragment trembled slightly, as if feeling fear, or as if it was issuing a threat.

Zhang Yuanjing immediately condensed a ball of pure spiritual energy, attached his divine sense to it, waved his hand, and sent it into the bone fragment.

The bone fragment vibrated, began to tremble violently, and then calmed down after a while. Zhang Yuanjing used his divine sense to guide it and found that the ball of spiritual energy had been annihilated, leaving nothing behind. He injected another ball again.

After repeated attempts, he finally succeeded in leaving a mark inside the bone fragment.

He used his divine sense as a bridge, using that mark to feel the changes in the bone fragment. This bone fragment did not contain remnant souls, nor was it a spiritual weapon, so it did not have the conditions to generate spirituality. However, its level was extremely high, and when it obtained a powerful force, it could stimulate some instincts. This instinct may have been possessed by the alien beast before its death, and after countless evolutions, it was finally deposited in this most important bone fragment.

If a cultivator of the same realm obtained it, they could use their own power to refine it, so that it could be used as easily as one's own arms and fingers.

Zhang Yuanjing's level was too low, so he did not have this ability. However, with the great power provided by the spine, it was possible.

He felt the changes in the power of the bone fragment, and from time to time, he guided the power of his divine soul into it through that mark, merging with its instinct.

As the power flowed, the light emitted by the entire spine gradually became brighter. However, this wonder only lasted for a few breaths before it suddenly dimmed. From far to near, the entire spine quickly became gray and dark. All the spines that had completely lost their light scattered like powder and completely mixed into the mud.

When the entire spine disappeared, only the bone fragment emitted fluorescence and inexplicable great power, suspended in the deep water, like an unparalleled divine sword.

Zhang Yuanjing simply raised his hand and grabbed it, and the bone fragment quickly moved and landed in his hand.

Zhang Yuanjing nodded in satisfaction and said to Lu and Luo, "The matter is complete, let's return to the sect!"
