Born with immortal seed

Chapter 407 The Five-Crystal Divine Iron in Burial Immortal Valley

"The three jade slips contain three different things: one is a metal-based cultivation technique that can be mastered to the Core Formation stage; another is a third-tier spiritual plant inheritance; and the last jade slip contains three pill formulas, all of which are suitable for Foundation Establishment stage cultivators..."

While flying on his sword, Bai Zichen did not forget to carefully read through the contents of the three jade slips he had obtained from the auction house's collection.

"It's of little use to me, but it adds to the sect's foundation, giving the Transmission Hall, Pill Hall, and Spirit Plant Hall a share of the legacy."

This trip to Zengguang Immortal City allowed me to witness the prowess of top-tier cultivators and the true power of the Heaven-Reaching Spiritual Treasure.

However, the failure to finalize the planned subcontracting of the Liangguo trade route is a great regret.

As for the personal aspect, since I didn't enter the Sky Tower, my gains were limited.

According to Yan Yuanzai, the Immortal Tower contained countless treasures, and even two secret realms were lost to the Du clan because they were unwilling to destroy them, resulting in the destruction of their populations and their fall into the hands of Tianfa Peak.

One is a secret realm of medicinal herbs, and the other is a secret realm where Xuanming Heavy Water can be refined, which can be considered to enhance the foundation of the Du family's strength.

Each Nascent Soul True Monarch who participated in the siege of Du Heng received some treasures, and Heavenly Punishment Peak also gifted each of them a top-grade spirit stone.

Fortunately, Bai Zichen gained something else.

If things really turn out as he imagined, then his gains would be no less than those of Nascent Soul True Monarchs.

"It overflows with sparks, burns eternally, and has a strong suction sensation when touched... It is completely consistent with the legendary Great Sun Gold Copper in every aspect, but whether it is the same thing or not cannot be determined at present."

The ore, which seemed to be burning eternally for countless years, appeared in Bai Zichen's hand, and the flames it emitted caused pain in his palm.

Even the Fire Dragon Returning to Origin Scripture couldn't absorb the flames on the surface of the ore; the fire dragon swallowed it, spun around in its belly, and then spat it out.

"If it really is Sun Gold Bronze, then I can start cultivating the Sun Heavenly Bronze Bone after I go back, and start the first step of the Nine Heavens Bone Forging Technique!"

As one of the three great inheritances of the Sword Immortal Secret Realm, Bai Zichen had always wanted to learn and cultivate the Nine Heavens Bone Forging Technique.

Unfortunately, the entry requirements are too high, with each of the seven immortal bones requiring cultivation becoming increasingly difficult.

Among them, the requirements for the Sun Yuan Copper Bone are the lowest; one can begin refining it as long as one has just entered the Core Formation stage.

However, it requires the use of thirteen special spiritual materials, and he has only managed to gather ten of them over the years.

The remaining three types are: Great Sun Gold Copper, which has only appeared in records and is a spiritual material that has not appeared in the Northern Region for ten thousand years.

The other two types are both valuable and can be used as materials for setting up a fourth-order grand formation.

However, as long as you are willing to spend a lot of spirit stones, there are still ways to purchase them from the Central Region.

If Bai Zichen can prove that the burning ore, after removing its impurities, contains the Great Sun Gold Copper, he will be very close to refining his first immortal bone.

In addition, he also has the basic conditions for cultivation with a piece of Heavenly Might Star Bone.

Once you reach the peak of Core Formation, the nine kinds of extraterrestrial iron spirit liquid will already be prepared, and you can directly begin refining the immortal bones.

Each immortal bone has a different function, and the remaining few immortal bones can only be refined at the Nascent Soul stage, so there is still a long way to go.

It's not that Bai Zichen is far from reaching the Nascent Soul stage, but rather that the remaining Immortal Bones all have other cultivation requirements, each one more exaggerated than the last.

Moreover, judging from the supernatural powers brought by the immortal bones, they are not weak, but they do not seem to be on par with the Supreme Pure Micro Sword Box and the Purple Star Thunder Sword.

The Supreme Pure and Subtle Sword Box is a rare treasure of the Heavenly Palace, a personal treasure of sword immortals in the Upper Realm, and a supreme treasure of the sword path.

The Ziwei Dazzling Thunder Sword is currently only at the third rank, but judging from its spirituality and the Moon Whirlwind Sword's reverence and obedience towards it, its essential rank is at least the fifth rank or higher.

Even if he refined all seven immortal bones and combined their supernatural powers, the feeling he would get from Bai Zichen would be at most similar to that of a fully-fledged Five-Crystal Glazed Body. Even if he were slightly better, there would be no qualitative difference.

However, judging from the other two treasures, the Nine Heavens Bone Forging Technique should not only possess such power.

"Perhaps with all seven immortal bones gathered, other changes will occur; we'll only know when we truly achieve our goal..."

Bai Zichen pondered to himself, put away the flame ore, and wondered which refining master he should find to test whether it was solar gold copper.

In the blink of an eye, we arrived at our destination.

The sword light leaped out of the towering gale layer and landed directly on the ground without even looking.

"Why didn't we hear the ancient demon's roar? Didn't they say that the ancient demon's range of activity has increased by fifty feet in recent years, and its roar is almost heard outside the Burial Immortal Valley?"

Bai Zichen glanced around and remembered that when he was still at the Foundation Establishment stage, he had come here with his senior brother Ge Cang.

He stood below, watching the two most powerful Core Formation cultivators from Liang and Beiyuan engage in a life-or-death battle on the arena.

It now seems highly likely that Du Heng was responsible for what happened that day.

Just as he was refining his True Demon Avatar and needed to consume blood and flesh to advance his cultivation level.

Du Heng, taking advantage of the positions of several Nascent Soul sects involved in this matter, used a few tricks to create a tournament like the Burial Immortal Valley Arena.

This allowed him to release the ancient demon, creating conditions for him to cultivate the True Demon Saint Body.

The secret Fang Tiansheng told him was that the chain that trapped the ancient demon was made of five-crystal divine iron at its core!
He longed to cultivate the final layer of the Five Crystal Glazed Body, and the two essential fifth-grade spiritual materials were actually located not far from his home.

He slowly walked towards the center of the Burial Immortal Valley. Although several Nascent Soul True Monarchs assured him that the Ancient Demon had no chance of escaping, he was still determined to succeed.

Even if someone were to openly and honestly try to dismantle it, they would still be unable to break the Demon Refining Formation.

That was the result of the collective wisdom of all the Nascent Soul cultivators, with the participation of cultivators from the Upper Realm. The spiritual materials used were ancient relics, which more than doubled the effect. That's why there was such a rare fifth-order spiritual material as Five-Crystal Divine Iron mixed in.

It was only because the inheritance that the Du family received when they rose to power was related to the ancient master who set up the array and transformed into a god that they were able to make limited use of the Demon Refining Array.

"We've arrived. You must concentrate fully on the method of collection; there can be no mistakes."

When Bai Zichen reached the vicinity of the large pit's fissure, the ancient demon had vanished without a trace, leaving only a dark void, likely having retreated back underground.

He summoned the Moon Whirlwind Sword and simultaneously flicked his finger lightly against the iron chain, causing it to vibrate with a clattering sound.

After changing several hand seals in succession, the iron chain was shaken high into the air, and a five-colored crystalline light spread out.

When the Demon-Binding Chains were forged, the Nascent Soul cultivator had considered the possibility that they might be broken by the ancient demons, so he left a way to replace each link of the chain.

This method was given to Fang Tiansheng by Du Heng, and then Fang Tiansheng gave it to Bai Zichen.

At that time, Fang Tiansheng was needed to lure the Blood God True Lord into a trap, so the reward he was given was not fake.

After several hours of trying, Bai Zichen finally found the knack, and the rhythm of striking the chains became uniform, with the five-crystal color rising and becoming increasingly intense.

Until a 'ding' sound, the most worn ring fell off.

The surface of the buckle was worn through several layers, showing signs of weathering and accumulating rust and dirt.

The exposed inner layers are all formed by the convergence of five crystals, condensing into a peculiar shape.

It is the Five Crystal Divine Iron, which is known as the hardest of the fifth-grade spiritual materials!
'It really worked! We got it!'

This ring is more than enough for Bai Zichen to cultivate his final Five-Crystal Glazed Body.

Moreover, since one strand of the long chain was missing, it looked exactly the same from the outside and would not affect the effect of suppressing the ancient demon at all.

'I'll refine this later and cultivate the Five-Crystal Glazed Body directly... I want to see how the Five-Crystal Glazed Body can change to its most perfect form.'

As Bai Zichen was fiddling with the Five Crystal Divine Iron, he suddenly felt a chill on his back, and a sharp, piercing light made him ache.

Even when everything went black, all that could be seen with the eyes and probed with the divine sense was pitch black.

"Who dares to launch a sneak attack!"
