151: Xuan Tian is number one!

At 1,580,000 years old, you finally pushed your Artifact Refining techniques to the level of a peak Artifact Refining Grandmaster.

In a desolate star field, you looked at the numerous Tribulation-level Materials before you and began refining a treasure.

With a thought from your fingertips, hundreds of millions of Artifact Refining hand seals instantly enveloped all the Materials. Each seal contained the ultimate principles of heaven and earth, the Dao of Creation.

After being struck by the hand seals, these Materials slowly merged within the Void Crucible, bursting forth with a brilliant light that made even the galaxy tremble.

During the refining process, you even integrated the exquisite structure of the nano spirit pearls, the Profound Truth deductions of the Heavenly Deduction Life Pivot, and the unique concepts of all the Spirit Treasures you had ever refined.

When the final seal fell, the entire Star Domain shook. An unprecedented high-grade heaven-reaching spirit treasure was finally born, which you named—xinji dayanyan!

This Spirit Treasure flowed with the Profound Truth light of The Dao Rule of Only Heart, Only Self, sometimes transforming into a magnificent galaxy, and sometimes condensing into a simple, ancient sphere.

This supreme treasure perfectly inherited the essence of your lifelong Artifact Refining. It could transform at will into the ultimate form of any Magic Treasure you had previously refined, and each form contained power many times greater than the original.

Most astonishing was its "All-Into-One" characteristic.

When you activated the Dragon bone Origin within it, it instantly transformed into a Dragon Bone Divine Spear that pierced through heaven and earth, its shaft entwined with the phantom of a Dragon soul possessing the pressure of a true Dragon.

When the Phoenix Essence was stimulated, it turned into a pair of Phoenix Heaven Divine Wings that blotted out the sun, each feather burning with True Nirvana Fire.

The Golden Crow Power condensed into the Crimson Sun Heaven-Ripping Claw that tore through the Void Realm, the Solar True Fire dancing on its tips enough to incinerate the eight desolations...

Every transformation of this supreme treasure seemed to demonstrate the ultimate mysteries of the Laws of Heaven and Earth.

At 2,980,000 years old, during these past million-plus years, you integrated over a dozen different Laws into The Dao Rule of Only Heart, Only Self. Each integration made your Dao Rule stronger and your Foundation deeper.

Additionally, you did not give up on comprehending the Laws of Heart, Five Elements, and Fate. Under such day-to-day accumulation, your Dao Rule grew at an incredible speed, finally reaching a critical point.

You felt the power within the Dao Rule boiling, like a volcano about to erupt, just one step away from a Breakthrough. You knew this was a sign of Dao Rule metamorphosis; once successful, your strength would leap to a new level.

The growth of a Dao Rule is not endless. When it reaches a certain limit, it stagnates, as if blocked by an invisible barrier.

This is the trial of heaven and earth for a Cultivator. Only by breaking through this barrier can one continue to climb to a higher Realm, and the method of Breakthrough is the metamorphosis of the Dao Rule.

Metamorphosis is no easy task. The powerful force generated during the process intensifies the conflict between Laws. However, this is a life-and-death trial that every Tribulation Transcendence Celestial Venerable must face to improve.

Once metamorphosis begins, there is no turning back. The consequences of failure are severe: at best, the Dao Rule is damaged and cultivation regresses; at worst, the Dao Rule collapses, leading to total annihilation of body and soul—a state known as a Dao Tribulation.

Throughout history, more than one brilliant Heavenly Venerable has fallen under the Dao Tribulation, turning into a wisp of dust.

Therefore, almost all Tribulation Transcendence Celestial Venerables will not push for a Dao Rule metamorphosis unless they are absolutely certain of success.

Based on what you learned from other human Tribulation Transcendence Celestial Venerables, there are no more than twenty Heavenly Venerables in the entire Profound Heaven Realm who have openly passed the first Dao Tribulation. Fewer than five have passed the second, and only Eternal Heavenly Venerate has passed the third.

However, in your eyes, a mere first Dao Tribulation was nothing more than a small ripple on the path of cultivation, unable to stop your progress toward a higher Realm.

You unhesitatingly pushed The Dao Rule of Only Heart, Only Self to begin its metamorphosis. With a single thought, the long-dormant Dao Rule power within your body began to boil, like a slumbering demon god suddenly awakening.

In an instant, your Dao Rule erupted with an incredibly strong power fluctuation, strong enough to shake an entire world.

If you weren't currently inside the internal space of your high-grade heaven-reaching spirit treasure, "xinji dayanyan," this power fluctuation would have definitely covered the entire Central Heaven World and attracted the attention of all Tribulation Transcendence Celestial Venerables.

Throughout these long years, you remained absolutely focused, guiding the metamorphosis of the Dao Rule with exquisite control. Although the many Laws making up the Dao Rule were restless, they could not cause any trouble under your powerful suppression.

You were like a skilled lutenist, plucking every string of the Law just right.

Finally, when the last trace of Dao Rule power completed its metamorphosis, your Dao Rule radiated an unprecedented brilliant light. At this moment, you clearly felt a closer connection with heaven and earth, and your understanding of the Dao reached a new height.

You passed the first Dao Tribulation perfectly, laying an even firmer Foundation for your future path of cultivation.

After passing the first Dao Tribulation, you asked Eternal Heavenly Venerate how many Dao Tribulations one must undergo in the Tribulation Crossing Realm, but unfortunately, even Eternal Heavenly Venerate did not know the answer.

At 4,210,000 years old, you successfully passed the second Dao Tribulation once again.

At 7,530,000 years old, your Realm surpassed everyone in the Profound Heaven Realm as you passed the fourth Dao Tribulation.

After passing the fourth Dao Tribulation, your perception underwent a world-shaking change. You discovered that with the support of the Dao Rule, you could enter a mysterious Realm at any time—the same perspective of the entire Profound Heaven Realm you briefly perceived when you first broke through to the Tribulation Crossing Realm.

This perspective was no longer a fleeting experience but had become a power you could control freely. You felt as if you had become heaven and earth itself; with a single thought, the mountains, rivers, plants, living beings, and even the breathing of Cultivators were all within your perception.
