Chapter 253: Mid‑Stage Flying Heaven Realm, Encounter the City Lord!

Inside the City Lord's residence.

Su Yu opened the Synthesis Slot.

He took out the Energy Stones from the past few days.

He took out a full forty pieces.

Ten per day over four days.

Although for the current Su Yu, forty Energy Stones are nothing, and they cannot even let Su Yu ascend to the late stage of the Flying Heaven Realm.

But it's better than nothing.

Moreover, this is a sustainable resource; given enough time, it will be perfect.

Furthermore, ten Energy Stones synthesized in the Synthesis Slot can produce one low‑quality Star Crystal.

Add the fifteen hundred pieces previously gathered in a Space Ring from Leopard City.

Now Su Yu has a full 1,540 Energy Stones on his person.

Su Yu synthesized the forty Energy Stones into four low‑quality Star Crystals.

Feeling the energy fluctuations within the low‑quality Star Crystals, Su Yu couldn't help but take a deep breath.

"It works indeed, I wonder if I can synthesize a Supreme Star Crystal!"

Su Yu took out five hundred Energy Stones.

After synthesis in the Synthesis Slot.

In the end, he produced one mid‑quality Star Crystal, one high‑quality Star Crystal, and six Supreme Star Crystals!

Looking at the six Supreme Star Crystals in his hand, Su Yu couldn't help but swallow.

These are Supreme Star Crystals; the entire Daxia can only exchange about fifty of them.

And he only used a little over five hundred Energy Stones to synthesize six Supreme Star Crystals.

"What a pity, if I had four more, I could upgrade a primary Energy Ore Vein to a secondary one."

Su Yu felt a bit regretful.

Although he still has a thousand Energy Stones left, Su Yu plans to cultivate with Star Essence Liquid and cannot move them.

"I'll keep them for now; once I have enough Energy Stones, I can upgrade."

Reluctantly, Su Yu placed the Supreme Star Crystals into the Space Ring, then set a thousand Energy Stones beside himself.

Immediately, an extremely dense energy fluctuation began to permeate the room.

Su Yu inhaled deeply and could feel the dense energy brewing in the air.

Then Su Yu took out a drop of Star Essence Liquid.

He swallowed it in one gulp.

The Demonic Devouring Heart Method whirred rapidly.

Cooperating with the Energy Stone's power, it gradually transformed the energy of the Star Essence Liquid into low‑grade Spiritual Qi.

Inside his body, the immensely dense Spiritual Qi swirled like a vortex, continuously rotating in Su Yu's dantian.

Each rotation absorbed abundant energy into the miniature Arhat Golden Body within his dantian.

After an unknown amount of time, the Arhat Golden Body in his dantian grew increasingly intense, even allowing him to see the opposite side through it.

The Arhat Golden Body became brighter.

In the next moment, the Spiritual Qi ceased, and the power of the Star Essence Liquid was completely absorbed by Su Yu.

Su Yu opened his eyes, and a flash of brilliance flickered through them.

His body was now filled with a surging energy that pervaded his entire being.

With a roar, a series of booming sounds emanated from his dantian.

Late‑stage Flying Heaven Realm—achieved!

A fierce aura hovered around Su Yu.

Su Yu couldn't help but clench his fist, his eyes bright as he stared into the void, and punched forward.

Thud!

A muffled sound echoed from the void, and the space visibly twisted for a moment before calming.

"With my current cultivation, even facing Luo Ping would no longer be that arduous."

"And… I can also unleash the Sixfold Thunder Demon Slash!"

Su Yu's eyes shone.

Having risen to mid‑stage Flying Heaven Realm, Su Yu's combat power increased markedly.

He can now unleash the Sixfold Thunder Demon Slash.

With a full 64‑fold power boost, plus Su Yu's current late‑stage Flying Heaven Realm cultivation, he can even contend with a mid‑stage Star Ancestor Master strong opponent.

But it is only enough for a single battle.

After that battle, he must seize the chance to flee.

The gaps between each sub‑stage of the Star Ancestor Master are very pronounced; unless Su Yu can trigger the Sevenfold Thunder Demon Slash with a 128‑fold power boost, he cannot slay a mid‑stage Star Ancestor Master strong opponent.

As for the late‑stage Star Ancestor Master, unless Su Yu ascends to Transcendent, even a 128‑fold power increase cannot defeat him.

Nevertheless, Su Yu's combat power is still extraordinarily terrifying.

Moreover, note that Su Yu is only at the Flying Heaven Realm.

Yet he can already compare to Grand Master‑level warriors; such terrifying power makes him among the elite across the entire Ten Thousand Tribes Continent.

"During ordinary times one can unleash the Sixfold Thunder Demon Slash; if one spares no expense, forcing the Sevenfold Thunder Demon Slash is also possible."

"Now my limit should be the mid‑stage Star Ancestor Master."

Su Yu gauged his own strength.

With Su Yu's current strength, placed across the entire Mist Race, he belonged to the top-tier existences.

After all, the number of those in the Mist Race who could possess the strength of a Star Ancestor Master was only around twenty or so.

Those were the powerhouses at the very apex of the Mist Race's pyramid.

At the thought of this, Su Yu's eyes flickered slightly.

"That's enough!"

Su Yu grinned.

Rubbing his pocket, Su Yu suddenly felt a bit of loss in his heart.

When Su Yu left, the little azure dragon was taken away by the Slay Dragon King, who said it needed proper training.

Though somewhat reluctant to part, Su Yu still supported anything that could raise the little azure dragon's strength.

Especially under the Slay Dragon King's personal guidance, the little azure dragon's strength would absolutely increase to an even more terrifying level.

There was also one more thought that Su Yu kept hidden in his heart.

Su Yu suspected... that the Slay Dragon King was not from this world.

After all, a creature like the azure dragon existed in the legends of Huaxia; in the Myriad Races Continent, a creature like the azure dragon had never appeared.

And in the Slay Dragon King's attacks, there were entirely the shadows of the azure dragon, and at the end he even erupted with a five-clawed golden dragon.

However, Su Yu did not reveal this suspicion.

This could be considered Su Yu's last secret aside from the Synthesis Slot.

Even though the Slay Dragon King was his master, he never asked.

If it turned out not to be so, wouldn't that be awkward.

There were some things Su Yu still planned to wait for the Slay Dragon King to tell him personally.

The fact that the Slay Dragon King hadn't spoken of it now must mean he had his reasons.

At this moment, the energy stones around Su Yu had already turned to fine dust.

Su Yu felt a pang of heartache.

One must know, these energy stones could be exchanged for over ten Supreme Star Crystals; if used to upgrade an Energy Ore Vein, it could already be upgraded to intermediate level.

But the moment he felt the vigorous fluctuations within his body, Su Yu felt at ease.

After a simple tidying up, just as Su Yu was about to head out to survey the situation in Mist City, a servant from the City Lord's Manor walked over respectfully.

"Young City Lord, the City Lord asks you to come to the main hall!"

Hearing the servant's words, Su Yu's eyes flickered slightly.

"True, it's about time to go see this 'old father' of mine!"

The corners of Su Yu's mouth lifted slightly, and then, led by the servant, he slowly arrived at the main hall.
