Boom——!

A thunderous noise erupted in Zhao Xuan's chest, reminiscent of a war drum, but amplified millions of times. Upon its emergence, it formed a visibly spherical shockwave, continuously spreading and expanding in all directions.

Possibly due to its overwhelming power, or perhaps because of being caught off guard, Jiang Wuji was instantly blown away, while Chen Zaikun resisted momentarily but was forced to retreat, his chest tightening as dark blood seeped from his mouth.

As for Kasima Reiko's avatar, it cracked apart in mid-air, spinning several times and nearly colliding with the building debris, threatening total disintegration.

Even Yun You, hiding behind the cover, felt her organs churn, with blood trickling from her nose, mouth, and the corners of her eyes.

"This is... 'Heart Shock'!"

In an instant, Yun You discerned the essence of this ability.

Heart Shock, a relatively common Death God Talent Ability, with effects quite simple—by stimulating the Sur Particles, one's heart becomes a "battery," compressing and storing energy, eventually releasing it entirely in one violent pulse, causing repulsion and damage effects to surrounding enemies.

Because its principle is straightforward, this ability is very prevalent among the Death God community, with nearly one in ten Apprentice Death Gods possessing this Heart Shock Talent.

However, common and simple does not imply weak.

On the contrary, any ordinary talent, once trained to the extreme, can rival rare talents.

Zhao Xuan's Heart Shock is precisely such.

"Be careful, this guy's Heart Shock isn't just a one-time thing; I've heard the old man say he can release it at least three times in a short span, and the power intensifies each time!"

Jiang Wuji barely steadied himself, hastily explaining to his fellow disciples, "Stay alert on defense, don't let this catch you off guard!"

"Alright!"

Chen Zaikun agreed, while Kasima Reiko gently nodded.

"This fellow has been the biggest enemy and rival to the old man for decades, it's a rare chance, we mustn't let him escape!"

Jiang Wuji muttered to himself, clasping his hands together and once more exhausting all his physical strength, preparing for the next "All Things in the Universe," wholly disregarding his physical condition.

Seeing this, Yun You was somewhat moved.

She had previously heard from Old Jin that over the decades, the old man had taken in many students, but the most special, aside from her, Yun You, were Senior Sister Erin and Senior Brother Jiang Wuji.

No need to elaborate on Senior Sister Erin, Senior Brother Jiang Wuji, despite his aloof personality and occasional disagreements with Old Jin on certain matters and directions, remained loyal to Old Jin.

The old man often mentioned that Jiang Wuji was the sharpest blade in his hand and his closest comrade in arms.

And now, Jiang Wuji's actions undoubtedly lived up to Old Jin's expectations.

"All Things... in the Universe!"

Before long, Jiang Wuji rasped and roared, once again summoning thousands of pointed branches to blast toward Zhao Xuan!

But Zhao Xuan, however, activated Heart Shock beforehand, unleashing a shock force even stronger than before, blocking the branches mid-air, significantly diminishing their impact.

Ultimately, only a few spikes struck Zhao Xuan's body, adding more wounds to his battered form.

At this moment, both Zhao Xuan and Old Jin's group had already exhausted their physical stamina and sustained some injuries.

Yet, none of them would surrender, nor would anyone cease the fight.

This battle could only end with the death of one side, in Old Jin's heart.

"For the next strike, Second Brother, I'll defend while you attack!"

Seeing Zhao Xuan continuously accumulating energy, preparing for the last Heart Shock, Jiang Wuji wiped the blood from the corner of his mouth and immediately made the decision.

His physical strength was already drained, unable to use the Ultimate Skill All Things in the Universe again, but Chen Zaikun still had enough stamina to attack.

Thus, he would forego the role of the main attacker, focusing entirely on shielding Chen Zaikun.

"Me attack? But... Big Brother, your body..."

Chen Zaikun's pupils shrank slightly, hesitating.

The power of Zhao Xuan's third Heart Shock was immense, and one misstep could be fatal.

Jiang Wuji was already exhausted, and now to bear the defense for him might result in serious injury...

Their friendship was already strong enough, and now watching his senior brother risk harm, Chen Zaikun, being a straightforward person, found it hard to decide.

"What are you hesitating for? Pathetic!"

Jiang Wuji cursed under his breath, growling, "Injured or not, as long as I help the old man win this battle, I'd die with a smile!"

"Attack!"

With that, he spread his arms wide, summoning some of his cautious powers, transforming them into a wooden shield around Chen Zaikun, leaving no room for his junior brother to hesitate.

Seeing this, Chen Zaikun understood that his senior brother was indeed determined to proceed this way.

He wanted to retort, but the words turned into...

"Alright!"

And so, shielded by Jiang Wuji, Chen Zaikun clenched his iron fist and charged at Zhao Xuan.

Meanwhile, the most powerful third Heart Shock was imminent.

"Heh..."

Zhao Xuan took a deep breath, driving all the Sur Particles into his heart until the energy reached its apex.

Crack—!

A sharp crack rang out as his heart, compressed to the limit, split open, tearing a five to six-centimeter gash, and under immense pressure, blood sprayed forth, piercing through his chest bone and muscle skin.
