152: Chapter 152 Immortal Artifact Upgrade

Seeing the upgrade rewards gifted by the System, Xiao Yuchen was still somewhat surprised. The System hadn't gifted a youth-preserving pill for a long time, and finally getting a top-grade one was, in a way, achieving his goal in one step.

Besides this, Xiao Yuchen was also very satisfied with the other two rewards.

The full name of this Seven Kill Formation is the Heaven-Darkening and Earth-Dimming Seven Kill Formation, and its characteristics are its eeriness and terror.

As a Rank six Formation, the lethality of the Seven Kill Formation is already quite impressive. Coupled with the eeriness and terror of this Seven Kill Formation, it will make those who enter the Formation feel fear, unable to maintain a clear mind, let alone break the Formation.

As for the Spirit Illusion Step, it is a movement Martial Skill. After cultivating it, one can not only gain a speed bonus but also perform short-range teleportation, which is absolutely capable of catching opponents off guard in battle.

Moreover, the Martial Skills and Cultivation Techniques gifted by the System are not ordinary items; even in the Cultivation World, they would be considered top-tier. On Earth, there is simply no one capable of forcing him to use the Spirit Illusion Step. Of course, using it to show off or intimidate an opponent is still fine.

Xiao Yuchen never liked to hoard Martial Skills; it was better to learn them sooner rather than later. Therefore, Xiao Yuchen directly retrieved the Seven Kill Formation and the Spirit Illusion Step from the System Inventory, and with the help of the System, he quickly mastered both skills.

"Having a System is truly great; no matter how many skills there are, I can master them very quickly."

Xiao Yuchen sighed with genuine emotion. The skills gifted by the System were all top-tier. If he had to research them himself, it would certainly take a lot of time and energy. The key point was that personal comprehension would always lead to mistakes, and sometimes those mistakes could be fatal.

After learning the skills, Xiao Yuchen took out a water Spirit Stone from the System Inventory and then used the Great Desolation Spirit Swallowing Technique to refine it.

With the experience of refining the fire Spirit Stone and thunder spirit stone previously, plus the upgrade of his Cultivation Technique, it only took Xiao Yuchen half an hour to completely refine the water Spirit Stone.

When the water Spirit Stone was finished being refined, Xiao Yuchen successfully achieved the Awakening of his water Spiritual Root. A small water droplet appeared in his Dantian, but before he could carefully admire it, the third Nascent Soul swallowed the droplet once again.

"Forget it, let it swallow it. As long as it doesn't affect my usage, it's fine."

Having achieved the Awakening of his water Spiritual Root, Xiao Yuchen could now use the Great Desolation Spirit Swallowing Technique to absorb water-attribute energy. However, upon arriving around this volcano, Xiao Yuchen discovered a problem: this kind of elemental power must reach a certain energy level before it can be absorbed.

Take this volcano, for instance. On the outskirts, it is really difficult for Xiao Yuchen to use the fire-attribute energy here to level up. Unless he goes inside the volcano or waits for the volcano to erupt, it won't be possible.

The absorption of water elements is the same. Hiding in calm water makes it difficult to absorb water-attribute energy; it must be when there is a typhoon, causing the seawater to move.

Or by going to places like waterfalls and hydroelectric power stations—only when enormous kinetic energy is formed can Xiao Yuchen obtain a large amount of elemental power from them.

Although he was a little disappointed, Xiao Yuchen quickly let it go. If it were that easy, he could just hide inside a volcano and reach the Tribulation Transcendence Stage very quickly.

Understanding this, Xiao Yuchen gave up the idea of using fire-attribute power to achieve a Breakthrough; he would just have to wait until the volcano erupted to absorb it.

Of course, the fastest method would be to devour a Sacred Fire, but the System didn't gift one, and he couldn't find any other Sacred Fire at all, so he could only wait for an Opportunity.

There was another reason why Xiao Yuchen gave up on cultivating. He had already reached the Nascent Soul Late Stage. Once he consolidated his cultivation base, he could directly take a Bu Yuan Pill to achieve a Breakthrough to the Nascent Soul Stage Great Perfection.

If he were to risk entering the volcano crater to Cultivate now, it might allow him to achieve a Breakthrough, but then his Bu Yuan Pill would be wasted, because after reaching the Nascent Soul Stage Great Perfection, taking a Bu Yuan Pill would be useless.

A Bu Yuan Pill cannot allow a Nascent Soul Stage Cultivator to cross the stage and achieve a Breakthrough to the Soul Transformation Stage. To achieve a Breakthrough to the Soul Transformation Stage, one needs to take a Soul Transformation Stage Pill. According to the System's consistent style, when he achieved a Breakthrough to the Nascent Soul Stage Great Perfection, the System would gift him a Soul Transformation Stage Pill.

Therefore, Xiao Yuchen was not in a rush to achieve a Breakthrough now. Anyway, the System was so thoughtful and had everything arranged; he just needed to wait. Moreover, these two upgrades—the last time he leveled up four times consecutively, and this time three times consecutively—this speed was already not slow.

Thinking of this, Xiao Yuchen took out the Black Gold Coiled Dragon Artifact Refining Furnace from the System Inventory. This was a reward gifted by the System when he achieved a Breakthrough to the Foundation Establishment Late Stage.

He still had three divine crystal stones in his hand. He had to upgrade the zhu xian sword, the lightning locking tower, and the god-devouring stele. Especially the lightning locking tower—this was a Divine Artifact essential for his Undergoing Tribulation, and its function was even greater than that of the zhu xian sword.

Thinking of the Undergoing Tribulation, Xiao Yuchen felt a bit puzzled. Treasures like the lightning locking tower that absorb lightning should be very rare; it was impossible for everyone to have one. So, how did Cultivators in the past survive the Lightning Tribulation? Did they just endure it head-on?

"Why can't I endure it? Is my body too weak? Or is it that I've been improving too quickly, lacking sufficient accumulation, and therefore cannot withstand the Lightning Tribulation?"

In fact, how could Xiao Yuchen understand? Cultivating is inherently a Heaven-Defying act. The more Heaven-Defying a person's talent is, the stronger the Lightning Tribulation they experience, and the greater the number of strikes.

Xiao Yuchen's talent had yet to be revealed; it was the System that was too strong, causing the Heavenly Dao to make an incorrect assessment and strike him vigorously. Of course, the System was indeed very reliable, gifting him the lightning locking tower.

After a brief reflection, Xiao Yuchen lit the Black Gold Coiled Dragon Furnace and threw the three divine crystal stones into it. Although the divine crystal stones were very hard, they could not resist the temperature of the Purple Heart Sacred Fire.

In just over ten minutes, the three divine crystal stones were refined into a red liquid. After filtering out the Impurities, Xiao Yuchen picked up the Purple Gold Coiled Dragon Furnace and poured the red liquid inside onto the lightning locking tower.

The red liquid flowed down from the top of the tower, and before it could reach the bottom, it was absorbed by the lightning locking tower. Treasures that have reached the level of Spiritual Artifact or higher can all autonomously absorb energy.

After the red liquid was completely absorbed, the lightning locking tower shone brilliantly, and the tower body trembled continuously, as if it possessed sentience; this was expressing its inner joy.

Xiao Yuchen placed his hand on the lightning locking tower, and the light on the lightning locking tower gradually disappeared, finally falling completely silent.

"Success!"

Xiao Yuchen was very excited; the lightning locking tower had finally successfully advanced to a Low Grade Divine Artifact. Although it only increased by one small Rank, there is a qualitative difference between a Divine Artifact and an Immortal Artifact.

If the previous lightning locking tower could store one hundred bolts of lightning, then the current lightning locking tower could store at least two hundred.

Of course, this is only in relation to the current lightning. As his strength increases, the Lightning Tribulation will also become stronger, and the stored quantity will decrease accordingly.

Therefore, it's not that Xiao Yuchen can sit back and relax just because he reached the Divine Artifact level; as long as he encounters suitable Artifact Refining Materials, he needs to continue upgrading the lightning locking tower.

Putting the lightning locking tower into the System Inventory, Xiao Yuchen then placed the zhu xian sword into the Purple Gold Coiled Dragon Furnace.

Ten minutes later, the zhu xian sword also emitted a sword hum, then flew into the sky, circling above Xiao Yuchen's head.

Xiao Yuchen beckoned with his right hand, and the zhu xian sword returned to his hand, which he then put into the System Inventory.

Next is the god-devouring stele. Once he reaches the Cultivation World, this god-devouring stele will be able to play a role. In the future, if he wants to improve his Soul Power, he will have to rely on the god-devouring stele.

Xiao Yuchen picked up the Purple Gold Coiled Dragon Furnace again and poured the remaining red liquid onto the god-devouring stele. In a short while, the god-devouring stele absorbed all the red liquid and successfully advanced to a Low Grade Divine Artifact.
