Chapter 2153: Watch closely, this is……

Swish!

A terrifying sword qi, or rather a terrifying energy surge, directly cleaved the Blood River Cave clean through!

Amidst a thunderous roar, the Blood River Cave collapsed a second time, this time completely destroyed, turning into an open-air environment.

Xun Shuang flicked her sleeve, sweeping away dust and rocks; the two sat on the rubble, spotless.

The violet‑gray treasure sword gleamed brightly in Xiao Feng's hand; under the sunlight, if you ignored its attributes, you would surely think it was a divine weapon!

"This sword is far more stable than before."

Xiao Feng said in surprise.

He flung his heart‑sword outward.

The heart‑sword became like a flying sword in a sword immortal's hand, soaring and darting under his control, weaving through the stone forest.

Whoosh whoosh whoosh!

Bang bang bang!

One after another, rocky peaks were pierced by the violet sword, erupting in waves of energy.

But half a minute later, the violet‑gray treasure sword flew back to Xiao Feng's hand, its contained energy undiminished, exactly as before!

Moreover, its appearance showed no change, as if it had truly become an independent artifact rather than a skill!

"This sword can wound me."

Xun Shuang glanced at the violet sword several times, then said.

Her physique is now very strong; although she looks like a fragile fairy maiden, even if several hundred gods attacked her at full strength simultaneously, it would be hard to harm her in the slightest, and even among same‑level primordial gods, few could wound her.

But this sword can easily pierce her defenses.

Xiao Feng said: "This sword shares your origin and has been refined into a weapon with exposed blade, like hammering iron or driving wooden nails into wood—naturally it can wound you. But unlike you, it lacks regenerative ability; ultimately it is merely a dead object."

Xun Shuang nodded slightly, then asked: "Aren't you supposed to study the secret technique? Is this your secret technique?"

Xiao Feng smiled: "No, still lacking. You've seen the heart‑sword; with your Innate Dao Body, plus my Dao Mark Scar, it can become the strongest."

All his skills, except the newly acquired Wither‑and‑Prosperity Method, had been demonstrated to Xun Shuang before.

This time, he won't hide it from her either.

However……

Xiao Feng did not act immediately.

Xun Shuang said: "Give it a try; I want to know just how terrifying the height you can reach is."

Xiao Feng immediately shook his head: "No, you must stay far away; the heart‑sword at this research stage is unstable—I myself have been blown up by it, and I don't want to hurt you."

Hearing this, Xun Shuang smiled wryly: "Fine, then I'll go watch from afar."

Having spoken, she rose, casually picked a direction, and was about to leave.

"Shuang'er."

Xiao Feng suddenly called out to her.

Hearing that address, Xun Shuang halted her steps and turned to look at him.

"Why have you become so distant lately? Weren't you getting better not long ago?" Xiao Feng asked, wearing a somewhat gloomy expression.

Xun Shuang blinked slightly, herself unsure how to answer the question.

After a moment, she replied: "It's been a long time since we last met; I forgot." Then she floated upward and flew toward a distant hill.

Xiao Feng widened his eyes, watching her depart, a flood of thoughts flashing through his mind.

It's been a long time since we last met?

Forgot?

All things considered, we haven't seen each other for less than a month!

Forgot what? Forgot the recent intimacy, so she's acting cold?

Xiao Feng was first startled, then secretly delighted.

Not seeing each other for over twenty days, she feels it's been a long time—doesn't that show she's already adapted to living together?

Isn't that right?

"A day apart feels like three autumns; over twenty days apart is roughly equivalent to several decades!"

Thinking about it, it really is a long time!

Xiao Feng's mood brightened; gazing at the distant hill where she sat in meditation, looking at his fairy maiden, he felt a surge of satisfaction.

"Shuang'er, watch closely—this is the height I can currently reach!"

He condensed two Dao Mark Scars, imprinting them onto the new version of the heart‑sword.

Then……

Boom—

A violet‑gray mushroom cloud rose from the ruins of the Blood River Cave; a terrifying shockwave swept outward, completely flattening the surrounding stone forest.

"Xiao..."

The hill where Xun Shuang the Fairy Maiden stood afar was also affected; she rose into the air, witnessed Xiao Feng being engulfed by the massive energy explosion, and, as an NPC's subconscious, deemed it lethal danger, instinctively wanting to rush to his aid.

But her first attempt to approach failed; instead, she was flung back by the spreading energy wave.

When she tried again, she realized Xiao Feng was a player—his death didn't matter—so she hovered in mid‑air, waiting for the dust to settle.

A few minutes later, the dust settled.

The original site of the Blood River Cave has been replaced by a circular pit with a radius of 20 kilometers.

Xiao Feng sat at the pit's center, his whole body grimy and dust‑covered, nearly turned into a statue.

"Cough, that… mistake, a bit of a mistake."

He explained embarrassedly.

Opening the battle information log shows that just now I mistakenly killed many god-level and demigod-level minor monsters.

At the same time, I also suffered an attack from the 'Unknown Skill', with damage reaching 300 zetta.

You should know, this is under the automatic body protection of the Kirin True Fire Throne and the continuous defense of the Indestructible Golden Body.

Result!

Moreover, he also has the Innate Dao Body's Ten Thousand Times damage reduction and the Supreme Holy Ring's massive defense and damage reduction.

Without these states, this hit would be enough to instantly kill him at least a hundred thousand times!

"You... okay?" Xun Shuang asked with a hint of worry.

She had thought Xiao Feng was dead, but unexpectedly he was unharmed, his aura strong, his vitality unaffected.

"I'm fine, I'm great! Really great!" Xiao Feng casually shook off the dust on his body, turning back into the handsome youth in novice cloth robes.

"Be careful." Xun Shuang sighed helplessly.

"Okay, my wife!"

Xiao Feng shouted, and after receiving concern he was greatly encouraged, immediately beginning to condense the new version Heart Sword and combine it with the Dao Mark Scar.

Then…

Boom~

Boom~

Boom~

One explosion after another, each time swallowing him.

Each time the Dao Mark Scar just touched the new version Heart Sword, a violent explosion occurred instantly, not even giving him a chance to throw it out.

The big pit on the ground kept deepening, gradually becoming like a well.

Finally he simply floated in midair to operate, not sitting on the ground, otherwise he'd probably blast straight through the earth's core…

Xun Shuang Xianzi, tens of kilometers away, watched him repeatedly detonate vast energy that swallowed him, finding it hard to bear watching.

"Xiao Feng Daoist, why not try again another day?" she advised.

"No, no, I must figure out the new version Heart Sword today!" Xiao Feng also became stubborn.

Failing repeatedly before the Fairy Maiden, he felt embarrassed and needed to establish his reputation with one successful new version Heart Sword.

So he continued trying to operate!

Then…

…

Boom~

Boom~

Boom~

Again, explosions repeatedly, each blasting his health bar down to one third, then the Supreme Holy Ring refills it fully.

Xun Shuang sat on a distant hilltop, watching the endlessly repeating scene, and couldn't help but sigh.

"Xiao Feng Daoist is truly persistent, not hesitating to injure himself so much for a single secret technique—no wonder he's growing so rapidly."

Xun Shuang Xianzi thought to herself.

Although the scene was a bit comical, she didn't want to laugh at all, and even felt moved!

Such perseverance, such determination, plus extraordinary talent, comprehension, strength, and... looks.

He would attract people, which seems not without reason…
