As his Chaos Sword Dao advanced to Level 30, his power soared. He broke past the limits of the Sixth Realm, condensing thirty-six Dao Sacred Seals, manifesting the Essence of Dao, and certifying his Primordial Saint Seal.

He exhaled slowly.

Xu Qing opened his eyes. He felt a deep understanding as, deep within his body, in the recesses of his consciousness, a magnificent sacred seal had manifested. It was the Primordial Saint Seal.

CRACK!

Xu Qing clenched his right fist, unleashing an immense burst of power. A terrifying force exploded around his hand, its Mighty Power seemingly infinite. This Saint Power was strong enough to crush space and time itself.

’So strong.’

’Truly powerful.’

"The Seventh Realm."

Xu Qing’s expression was contemplative. "Comprehending the ’Essence of Dao’ can also be called ’Certification’. This is the so-called ’Certification of the Dao to become a Saint.’ The Seventh Realm is the Saint Realm."

"The Saint Realm is divided into three tiers, from lowest to highest: Saint, Great Saint, and Saint King. Each of these tiers is further divided into the Nine Layers of Heaven."

"Right now,"

"thirty-six Dao Sacred Seals manifested the Essence of Dao, certifying one Primordial Saint Seal. Because I only have a single Primordial Saint Seal, my current Cultivation is at the First Heaven of Saint Realm."

"Only by continuing the process of Certification and obtaining more Primordial Saint Seals can I step into a higher Realm."

Time passed.

In the blink of an eye.

「Seven days later.」

BOOM!

With a single thought, Xu Qing’s Saint Power erupted from his body. He had completely consolidated his current Cultivation and Realm.

"Not bad."

Xu Qing assessed his condition and nodded in satisfaction. "Now, I can continue entering the Level 10 Damaged Time Treasure Tower. Having stepped into the Seventh Realm, I can access its 30th layer. There, I can achieve a time acceleration of one hundred million times."

Moreover, now that his Cultivation had increased and he had entered the Seventh Realm, the Level 10 Damaged Time Treasure Tower and the Level 10 Chaos Origin Sword Array Map—both Supreme Treasures—could be upgraded.

The first step was for Xu Qing to start accumulating Experience Points for both the Level 10 Damaged Time Treasure Tower and the Level 10 Chaos Origin Sword Array Map.

He wanted to upgrade these two Supreme Treasures first.

"Let’s begin."

HUMMM!

Xu Qing sat cross-legged. With a single thought, he sensed the existence of the River of Time. With a wave of his right hand, he tossed the Level 10 Damaged Time Treasure Tower into it.

...

[Experience +1]

...

[Experience +1]

...

Time passed, and the Experience Points for the Level 10 Damaged Time Treasure Tower began to grow rapidly...

It could gain one hundred million Experience Points per day.

Currently, the Level 10 Damaged Time Treasure Tower required 51.2 billion Experience Points to upgrade, which would take exactly 512 days.

That was close to a year and a half.

Time flew by.

In the blink of an eye.

「Two years passed.」

Xu Qing let out a breath.

He opened his eyes, took a deep breath, and reached out his right hand, pulling the Level 10 Damaged Time Treasure Tower from the River of Time.

"Good."

Xu Qing smiled as he examined the Black Pagoda in his hand. He connected his consciousness to the Encyclopedia of All Things, and the corresponding information appeared in his mind.

...

[Damaged Time Treasure Tower Level 10: 73 Billion / 51.2 Billion (Upgradeable!) (...)]

...

"Upgrade," Xu Qing said.

BOOM!

The moment he spoke, the Encyclopedia of All Things flashed with an intensely brilliant nine-colored light. Countless images flickered by, and within them, a vast Immortal aura was rapidly injected into the Time Treasure Tower, causing it to undergo a transformation...

...

[Upgrade Successful!]

[Damaged Time Treasure Tower Level 11: 21.8 Billion / 102.4 Billion (Having absorbed a large amount of Immortal Substance, its quality has been further upgraded...)]

...

"Good."

Xu Qing nodded in satisfaction.

’Just as I expected.’

’With the level increase, the Black Pagoda, which originally had only thirty layers, has gained another layer, bringing it to thirty-one.’

"Not bad, not bad at all," Xu Qing murmured, nodding in satisfaction.

Moreover, the maximum time acceleration on the thirty-first floor of the Black Pagoda had reached one hundred and ten million times.

"This will do."

Xu Qing nodded.

And so, Xu Qing decided to continue upgrading it.

Time flew by.

In the blink of an eye.

「Ten years passed.」

During this decade, Xu Qing had kept the Time Treasure Tower in the River of Time for the full ten years, accumulating a massive amount of Experience Points.

With a thought, Xu Qing connected his consciousness to the Encyclopedia of All Things, and the relevant information appeared in his mind.

...

[Damaged Time Treasure Tower Level 11: 386.8 Billion / 102.4 Billion Experience Points (Upgradeable!) (...)]

...

"Good."

Xu Qing nodded and said thoughtfully, "Upgrade the Level 11 Damaged Time Treasure Tower."

...

[Upgrade Successful!]

[Damaged Time Treasure Tower Level 12: 284.4 Billion / 204.8 Billion Experience Points (Upgradeable!) (Absorbed corresponding Immortal Substance, further enhancing its grade and manifesting the ’Thirty-Second Layer’.)]

...

[Upgrade Successful!]

[Damaged Time Treasure Tower Level 13: 79.6 Billion / 409.6 Billion Experience Points (Absorbed a large amount of Immortal Substance, its grade has been enhanced, manifesting the ’Thirty-Third Layer’.)]

...

"Hmm."

Xu Qing nodded thoughtfully. "A full ten years have passed, and I’ve only managed to upgrade it by two levels. As the level increases, the required Experience Points will only grow larger and larger."

"Therefore..."
