Seeing the underworld spirits charging at him, Lin Chen's eyes turned cold, and a white ball of flame shot out from his palm.

With a thunderous roar, the fireball instantly exploded over their heads.

Boom boom boom!

The fireballs shone brilliantly, much like meteors, crashing down on the underworld spirits.

In an instant, the spirits rushing at Lin Chen were reduced to ashes.

"How is this possible!"

Witnessing this, the faces of the onlooking underworld spirits turned pale.

One should know that Lin Chen had just instantly killed an Underworld Envoy and nearly a hundred underworld spirits; his power was simply overwhelming.

This crushing victory made everyone who had just scorned Lin Chen draw a cold breath.

In the underworld, the strength of an Underworld Envoy is considered top-notch. Even an Underworld King needs some effort to kill an Envoy, yet Lin Chen did so instantly.

Lin Chen's Heart Scorching True Flame is specifically effective against Soul Bodies, which is why its effect is so remarkable.

"Who else dares to challenge me? Come forward, or else pledge allegiance to me at Southwest Mountain or get lost from Rock Hill." Lin Chen spoke with a chilly voice.

"Hmph, just Southwest Mountain and you dare to boast at Rock Hill? Utterly seeking death." With a cold voice, a shadow darted out from Rock Hill.

Lin Chen glanced at that guy, realizing it was a formidable Underworld King.

"You're not convinced?" Lin Chen asked coldly.

"Hmph, of course not." The Underworld King snorted coldly.

Their words clashing, the two engaged in combat, with Lin Chen delivering almost a single lethal blow to subdue the king.

Seeing the cold Heart Scorching True Flame in Lin Chen's palm, the Underworld King's spirit trembled and he knelt to beg for mercy.

In Rock Hill, this Underworld King held a high status; with even him submitting, naturally none would dare resist.

Before long, apart from a few hundred who managed to escape Rock Hill, the rest expressed willingness to submit to Lin Chen.

Soon, all those who surrendered at Rock Hill gathered at the square, and Lin Chen counted over eighteen thousand. Such strength is enough to be considered a small force in the underworld.

Among these ten thousand, there are about three hundred with Envoy-level strength, three Underworld Kings, and these individuals are seasoned from roaming the underworld, making their combat experience very strong.

In fact, if they all attacked Lin Chen together, Lin Chen might only have managed to flee.

However, Lin Chen's recent overwhelming tactics implanted fear within them. Knowing even an Underworld King could be killed in an instant was enough to intimidate these powerful beings.

Having lost their physical bodies, with only their Souls remaining, they understood the preciousness of life even more, so without absolute certainty, they wouldn't risk their lives.

Reorganizing these forces, Lin Chen gave an order, and eighteen thousand strong warriors swarmed towards Southwest Mountain.

Lin Chen had already used the Heart Capturing Technique to control the three Underworld Kings, and since most of the others were their subordinates, controlling these three meant nearly twenty thousand were also under his control.

"Master, why don't we storm Southwest Mountain, and you can directly become its lord?" said a powerful Underworld King named Blood Eagle.

Lin Chen shook his head, "If the City Lord of Southwest Mountain knows to submit, there is no need to resolve it by force."

At the entrance of Southwest Mountain, Di Long snorted disdainfully, "Hong Ling, don't wait anymore, that kid is probably dead."

Hong Ling also sighed inwardly, knowing better than anyone what kind of place Rock Hill was. Although Lin Chen had impressive strength, surviving in such a deadly place was unlikely.

"Hmph, Di Long, I won't join your team, we're deciding to break away from Southwest Mountain." Hong Ling said sternly.

"Breaking away from Southwest Mountain means execution for disobedience, according to the mountain's laws!" Di Long's eyes flashed with ferocity.

With that, Di Long's eyes turned cold, and with a wave of his hand, his warriors surrounded more than fifty people.

"Kill all of them, leave Hong Ling to me." Di Long's eyes gleamed with cold, bloodthirsty fury.

Just as they were about to act, suddenly a subordinate ran over in a panic.

"Not good, we're under attack!"

"What, how many are they?" Di Long's face changed.

"Roughly close to twenty thousand." The subordinate answered with a pale face.

"What? Twenty thousand!" Hearing the subordinate's report, Di Long was dumbfounded.

This couldn't be; how would such a strong force appear nearby? Could it be that the guys from Hei Feng Ridge have all come out in full force?

Just then, another scout came running back: "Captain Di Long, the one leading them is Lin Chen, and behind him seems to be the people from Rock Hill."

"This can't be, that kid actually subdued the people from Rock Hill." Instantly, Di Long was dumbfounded.

At this moment, a burly man walked hastily out from the entrance of Southwest Mountain.

"What's happening?" the big man said coldly.

Di Long's expression was terribly grim: "Brother Nan, it's not good. One of Hong Ling's subordinates has subdued the people from Rock Hill and is now coming at us."

"What, Hong Ling's subordinate?" Nan Tian's expression changed at once.

By now, Lin Chen had brought the people from Rock Hill, advancing fiercely and aggressively.

Seeing Lin Chen, Hong Ling's eyes showed a complex expression.

Just earlier, when they were besieged by demon beasts, Lin Chen had already demonstrated exceptional strength, and now he had subdued all the strong forces of Rock Hill alone.

What kind of monster is this guy?

"Lin Chen, you finally made it back. Had it not been for you earlier, Miss Hong Ling and we would have met a grim fate." A member of the Demon Sealing Squad said with lingering fear.

Hearing those words from the squad member, Lin Chen's gaze turned cold, focusing on Di Long, whose face turned pale.

Di Long had assumed Lin Chen was certainly dead, but he never imagined that not only had Lin Chen survived, but he also subdued the strong forces of Rock Hill and came back.

At this point, Nan Tian awkwardly smiled, "This young brother, is there something you need by bringing these people to my Southwest Mountain?"

Lin Chen didn't respond, but an Underworld King said coldly, "From now on, this place is our master's territory. Submit and thrive, oppose and perish. Will you yield?"

"I..." Nan Tian's eyes flickered. From the bottom of his heart, he didn't want to surrender, but although he had many men, the other side included three Underworld Kings, and Lin Chen's power was even more unfathomable.

"Will you yield or not!" The eighteen thousand Underworld Spirits shouted with a terrifying voice.

This momentum frightened everyone from Southwest Mountain present.

Clenching his teeth, Nan Tian finally said, "I am willing to yield!"

Hearing Nan Tian submit to Lin Chen, Di Long's face turned even uglier.

He knelt down with a thud before Lin Chen: "My Lord, I was blind, please forgive me."

Lin Chen looked coldly at Di Long: "We agreed on one hour earlier, yet you acted against Hong Ling before the time was up. You know I despise people who break their word."

With that, a white flash emanated from Lin Chen's hand.

A Heart Scorching True Flame instantly enveloped Di Long, turning him to nothingness.

Seeing Lin Chen's ironclad methods, everyone present gasped.

Lin Chen's eyes flashed with golden light, and he also controlled Nan Tian, making both Southwest Mountain and Rock Hill territories his.
