Ji Jiayu's spiritual power carefully spread forward, and after differentiating into tentacles, he gently placed them on the Holy Light Pearl phantom. The next moment, the Holy Light Pearl phantom appeared before his eyes.

Ji Jiayu withdrew his spiritual power tentacles, and the Holy Light Pearl phantom disappeared without a trace.

"So it's spiritual power." Ji Jiayu immediately understood.

Immediately after, he drew his gourd and summoned the Holy Radiance Phantom again, observing it closely. From the outside and inside, there was nothing particularly surprising about it. However, its abilities were bound to be extraordinary; after all, this was a divine item that the Guangming clan would use all their might to control.

Ji Jiayu thought for a moment, divided a second spiritual power tentacle, and lightly touched the Holy Light Pearl phantom in front of him. The moment his spiritual power came into contact with the Holy Light Pearl phantom, Ji Jiayu's mind suddenly flashed with countless ways to use the Holy Light Pearl.

He immediately revealed a joyful expression and then used his spiritual power to wrap around the Holy Radiance Orb phantom. The next moment, a pale golden light shot out from the Holy Radiance Orb phantom, shining in all directions. Ji Jiayu looked around and discovered that the pale golden light enveloped the surrounding five hundred meters.

However, Ji Jiayu didn't fully understand the power of this pale golden light, and he speculated that it was most likely not an offensive ability, as it consumed very little mental power and lacked that deadly feeling.

Next, Ji Jiayu injected his spiritual power into the Holy Radiance Orb phantom.

In the next instant, the images in their visions changed.

He saw an endless world divided into pure gold and pure white, one above and the other below, like two heavens, and he floated in the middle of the two heavens.

His spiritual power surged upward, and after a moment, he arrived at the golden world and sank into it. It felt like his body was enveloped in water.

As his spiritual power merged with the golden world, the Holy Radiance Orb phantom bloomed with brilliant golden light and projected onto Ji Jiayu. The golden light melted into his body, causing changes to his divine skin and divine bones.

Patches of pale golden scales appeared on the surface of his skin, then fluttered slightly, emitting a faint golden mist, giving him a sense of unparalleled strength and speed. Furthermore, he believed his defensive capabilities had also been greatly enhanced.

The changes in his sacred bones were even more profound. The surface of his arms was surrounded by halos of pale golden lines. With the blessing of the golden lines, the sacred bones could withstand even more divine power, and the hematopoietic function of the bone marrow became even stronger. The divine power contained in his blood flowed throughout his body, transforming his temperament from the inside out.

Compared to himself, Nie Lanxi, who was sitting next to him eating grilled fish, felt the changes even more clearly. Ji Jiayu had become much stronger, much stronger in an instant, and his physical fitness had become stronger in all aspects. With this level of physical fitness, he could already perform some basic sacred techniques.

With a fourth-rank body capable of casting sacred techniques, he could essentially be said to be invincible within the fourth rank. But Ji Jiayu's changes went beyond that.

After extracting his spiritual power from the golden world, Ji Jiayu immersed his spiritual power into the white world again, and now, the phantom of the Holy Light Pearl projected a white light. The white light shone on Ji Jiayu, and the divine circuit in his body expanded rapidly, becoming more than five times wider in just a few seconds, and its toughness also greatly increased.

If Ji Jiayu's divine circuit was previously a rural dirt road, now his divine circuit is a bluestone main road connecting the cities of the Holy Kingdom, and the two are unmatched.

The change in his divine circuit means that Ji Jiayu's divine power output will be greatly increased, five times that of a normal early-stage Fourth-Rank Ming Zun. Of course, this is based on Ji Jiayu possessing a large amount of divine power.

So does he have it? Absolutely. His divine beacon is planted deep in the sacred sea, and due to his constant meditation, he can absorb a large amount of divine power at any time.

This level of divine power output gives Ji Jiayu the ability to use divine magic.

After completing the test of both abilities, Ji Jiayu opened his eyes, looked at Nie Lanxi eagerly, and said, "Did you see it?"

"Hmm." Nie Lanxi nodded.

"These two changes, I think one is called the holy form and the other is called the radiant form, which can enhance the abilities of the priest and the priestess respectively. How does it feel? Is it still dead now?" Ji Jiayu asked, a hint of self-satisfaction in his tone.

"It's much better, but it's still dead." Nie Lanxi said.

"It's okay, I can learn some sacred arts now." Ji Jiayu was stunned for a moment, then said happily. The scrolls Wang Yinlan had given him previously recorded fourth and fifth-order cultivation methods, as well as some sacred techniques, and now he could use them.

"Learn it," Nie Lanxi said.

Ji Jiayu smiled for a moment and was silent for a moment. He really wanted to say to her: Can't you have a little more expression when you speak? It's really a bit perfunctory to talk like this!

But in the end, he still didn't say anything. After all, they weren't familiar with each other, and they had only known each other for a short time, so there was no reason for him to greet her with a smile.

But before learning the sacred techniques, Ji Jiayu had a small request.

"Can I eat this?" Ji Jiayu looked at the grilled fish on the fire and swallowed.

"Catch it yourself," Nie Lanxi said.

Although he had long known Nie Lanxi would answer this, Ji Jiayu still sighed and walked to the river not far away.

After filling his stomach, Ji Jiayu took out the scroll and settled down to study.

Sacred arts were a priest's meticulous use of divine power, and a priest would actually use other methods. Compared to sacred arts, the methods used by priests were more complicated. Even if Ji Jiayu's sacred skin and bones were extremely powerful, he still couldn't try.

He could only study sacred arts for now.

There were many types and attributes of sacred arts, but they were all things a fifth-level Ming Zun needed to consider, and Ji Jiayu could only learn the most basic sacred arts at the moment.

There were many types of sacred arts recorded in the scroll, but time was tight, and Ji Jiayu could only learn one, so he considered and chose.

He had to first sort out his strengths.

Firstly, when it came to using the sacred form and the radiant form, his divine circuits were wide and resilient enough to withstand the surge of divine power. Secondly, his sacred bones and the texture of his sacred skin had the ability to withstand far more than cultivators of the same level, and could withstand a certain degree of counter-shock force. Secondly, his total divine power was vast, high-quality, and possessed certain god-level characteristics. Finally, he recovered quickly and possessed strong "endurance."

After Ji Jiayu listed the advantages, making the choice naturally became simpler.

"Holy Flame Baptism."

Although the Holy Flame Baptism was a first-grade holy technique, the appropriate cultivator was actually a fifth-grade Ming Zun. As a first-grade holy technique, the Holy Flame Baptism possessed power that surpassed many second-grade holy techniques. However, despite its power, it also had many drawbacks.

Firstly, this holy technique consumed a great deal of divine power, and a large amount of divine power was burned almost constantly. At the same time, it was also extremely harmful to the body, requiring divine power to be burned while circulating in the holy circuit. Furthermore, its large scope weakened its power to a certain extent and increased consumption. Finally, it was difficult to learn.

Learning this technique was difficult, which meant the requirements for the cultivator's body were relatively high.

After all, this was a holy technique that most divine cultivators would not choose, and there were often people from the Guangming clan who complained that this was simply not a holy technique created for a fifth-grade Ming Zun. How could a normal fifth-grade Ming Zun learn it, and where could it be used?

But this was precisely the case. Wang Yinlan told him that this sacred technique was not specifically designed for a fifth-level Ming Zun, but was created for him by a genius of the Light Clan. Later, as his strength increased, the Light Clan genius studied and created more sacred arts, so he didn't improve on the Sacred Flame Baptism, leaving this sacred art untouched.

However, this sacred technique happened to be very suitable for Ji Jiayu.

His physical fitness was excellent, no matter how many divine circuits were used, he wouldn't be injured, and he possessed so much divine power that he didn't know how to use it at all. However, the divine light sacred art was too crude, and he still needed to learn some special sacred techniques like the Sacred Flame Baptism.

This was simply a sacred technique tailored for him!

Ji Jiayu was extremely excited and began practicing without much thought.

The first step in learning any sacred art was to use his spiritual power to sense the divine power in the air, arranging it in a certain orderly trajectory, thus accommodating the divine power of oneself and the world, and meeting the requirements for performing the sacred art.

Generally speaking, the spiritual power level of cultivators who have just entered the fifth order has just started and is generally very weak, so it will be difficult for them to guide divine power and cannot be of any use, but Ji Jiayu is different, he has been learning to use divine power for a long time.

Under Nie Lanxi's gaze, Ji Jiayu's spiritual power spread out, and the scattered divine power arranged itself in the world before him. Almost in the blink of an eye, a path belonging to the sacred flame baptism of a first-grade sacred technique was formed. In the next second, a vast amount of divine power flowed from the divine circuit in Ji Jiayu's body to his palm, then surged out wildly, injecting itself into the mysterious path in front of him.

The wandering divine power was attracted and converged. In a very short time, flames rose in the mysterious path, and the flames gradually warmed and changed color, finally blazing fiercely.

Seeing the vast red flames, Nie Lanxi instinctively frowned, sensing a hint of danger.

He was immediately slightly startled. Ji Jiayu was only a fourth-grade saint, and it actually made him feel a hint of danger, which was quite extraordinary.

After careful observation, he judged that the reason Ji Jiayu's Sacred Flame Baptism was so powerful was due to the trace of god-level characteristics within his divine power.

After all, a god was a god, and it was not something a low-level cultivator could match in any way.

The crimson flames burned, showing no signs of extinguishing, occasionally curling in the air during Ji Jiayu's high-speed output test.

Five minutes later, Ji Jiayu still looked as usual. His divine power hadn't been consumed too much, and was constantly being replenished. Whether it was his holy circuit, holy skin texture, or holy bones, there were no signs of burning.

After a few more minutes, Ji Jiayu was almost tested, so he opened his eyes and looked at Nie Lanxi.

"Okay, we can set off now!"

In fact, if there wasn't a real opponent, normally, he wouldn't have made a positive judgment, but Nie Lanxi's previous frown and vigilance gave him confidence.

Nie Lanxi was like this, were those fifth- and sixth-level Demon Venerables unnecessary? As for the seventh-level Demon Emperor, he could only watch at that moment. It really wasn't possible, and he had his own methods.
