Just as Zhang Yu was about to lead the Li Family to defeat the besieging army, Li Yuansheng suddenly spoke up to stop him, "Wait!"
Zhang Yu turned his head in confusion:
Why?
Li Yuansheng's expression was solemn as he said in a deep voice:
"The current commander of the opposing force is Zhou Xuan, the King of the South, who is at the peak of the Heavenly Immortal realm. He also has two late-stage Heavenly Immortals under his command, as well as more than a dozen early-stage and mid-stage Heavenly Immortals."
Although we have two Late Heavenly Immortal Combat Power, the enemy's lineup is too powerful. If we rashly leave the city, we risk annihilation.
Zhang Yu was somewhat surprised to hear this:
"How did the Li Family manage to hold out for so long against such a formidable opponent?"
Li Yuansheng smiled wryly:
"Our Li Family has been able to hold on until now entirely thanks to the City-Guarding Grand Formation, and... a treasure."
A significant reason why the Sacred Dragon Divine Dynasty attacked my Li Family this time was for this treasure.
"Treasure?"
A glint of shrewdness flashed in Zhang Yu's eyes:
"What treasure?"
Li Yuansheng shook his head:
This is not the place to talk.
With that, he ignored the questioning looks from the others and led Zhang Yu away from the Great Hall, heading deeper into the Li Family Ancestral Land.
The two passed through numerous restrictions and arrived at a deep, dark cave.
The cave entrance is ancient and weathered, bearing the marks of time, and a faint sense of terrifying pressure permeates the air.
"This is... the Li Family Ancestral Land?"
Zhang Yu sensed several decaying yet still vast auras emanating from within the cave, and understood what was going on.
These are probably the hidden "Old Monster" in the Li Family that Xu Xinwu was referring to.
Li Yuansheng nodded, his expression respectful.
"The three Progenitor then secluded themselves in the cave."
The two entered the cave.
The cave was dimly lit, yet the Spiritual Qi was as dense as mist, with Principle Fragments faintly visible.
After going a hundred feet deeper, three ancient stone platforms appeared ahead.
On each stone platform sat an old man with white hair and beard, and a withered face.
The three of them were extremely weak, like candles flickering in the wind, seemingly about to be extinguished at any moment. However, the terrifying Daoist aura that faintly flowed around them revealed their former glory.
"Paying respects to the three Progenitor."
Li Yuansheng bowed respectfully to the three of them.
Zhang Yu's gaze swept over the three people, and he was slightly startled.
These three were all once at the peak of the Heavenly Immortal Peak!
But now, their aura has weakened, their Cultivation has plummeted, and they can barely maintain the strength of the Early Heavenly Immortal.
Moreover, their vitality is exhausted, and they are in danger of dying at any time.
"Yuansheng, you've arrived..."
The old man in the center slowly opened his eyes, which were cloudy and lifeless.
He looked at Li Yuansheng, then suddenly his expression changed. "Your injuries have healed?"
"No, not only have your injuries healed, but your Cultivation has also improved. What happened?"
Another old man, his eyes also Golden Light, stared at Li Yuansheng in disbelief.
When Li Yuansheng was injured, he came here to seek their advice and help, but they were all helpless.
But the injuries that even the three Old Monster couldn't cure have now been completely healed, which shocked them greatly.
Li Yuansheng made no attempt to hide anything, pointing at Zhang Yu and saying, "My injuries were able to heal completely, and even my Cultivation further, all thanks to this descendant of the Dao Ancestor's lineage."
"A descendant of Dao Ancestor Li?"
The three withered old men looked at Zhang Yu at the same time, their hearts filled with doubt and shock.
"Good, good... Even with the Dao Ancestor away, there are still such outstanding bloodlines. It's truly a blessing that Heaven hasn't forsaken the Li Family..."
The elderly man in the center nodded slowly, a hint of relief in his eyes.
Li Yuansheng spoke again:
"I brought Li Yu here today for two reasons."
First, Li Yu possesses extraordinary Medical Skills. I brought him here to see if he could resolve the backlash injuries from that treasure for the three Progenitor.
Secondly, he wanted to activate that Law Treasure to launch a counterattack against the Sacred Dragon Divine Dynasty.
The three of them were shocked upon hearing this.
They had long since given up hope, for over the years they had searched for renowned doctors and exhausted all the heavenly materials and earthly treasures, yet their injuries showed no improvement and their life force continued to ebb away, leaving them only to wait for death in this cave.
In fact, the outside world had already assumed that they had Incarnation long ago.
Very few people in the world know that they are still alive.
How Xu Xinwu obtained this information remains unknown.
But now that they've heard Zhang Yu can heal Li Yuansheng's fatal wound, they wonder if their injuries can too...?
This rekindled a glimmer of hope in their long-dead hearts.
"Li Yu, see if you have a solution."
Li Yuansheng asked anxiously.
The three old men stared intently at Zhang Yu, a faint glimmer of hope appearing in their cloudy eyes.
Zhang Yu looked at the three people, and with his Divine Sense spreading out, he sensed a familiar aura emanating from them.
"No need to look anymore, they were injured by the Exterminating Immortal Sword."
At this moment, the system suddenly spoke:
"The treasure of the Li Family should be an Exterminating Immortal Sword Fragment."
And judging from its appearance, it was quite a large fragment; otherwise, these three wouldn't have been injured so badly.
"I see."
Zhang Yu nodded silently and asked:
"May I ask the three Progenitor, how did you acquire these injuries?"
"Sigh, it's all because we overestimated ourselves."
The old man in the center spoke slowly, his voice hoarse:
"I suppose you've heard from Yuan Sheng that my Li Family possesses a treasure, and it is thanks to this treasure that the Li Family has been able to barely withstand the attack of the Sacred Dragon Divine Dynasty."
The old man on the left chimed in:
"Back then, the three of us old fogies accidentally obtained a broken sword with terrifying power. We were overjoyed and wanted to refine it."
But we completely overestimated our own strength.
The Sword Intent of that broken sword was too fierce; when we forcibly refined it, we were injured by its Sword Intent.
The old man on the right sighed:
"Moreover, that Sword Intent is extremely difficult to deal with, like a malignant tumor clinging to the bone, entrenched deep within our Divine Soul, constantly eroding our vitality and corrupting our foundation."
We've tried everything to get rid of it, but to no avail. We can only hide here, barely clinging to life.
Li Yuansheng then said:
"Later, the three Progenitor realized that this sword could not be refined, but they were unwilling to let go of this treasure. So they built a city here, set up Formation, and used the broken sword as the Formation Eye."
"That's why the Li Family's City-Guarding Grand Formation is so powerful that it can stop the Sacred Dragon Divine Dynasty's army."
A knowing glint flashed in Zhang Yu's eyes:
"I suppose that broken sword is the Exterminating Immortal Sword."
Otherwise, it would have been impossible to injure three Heavenly Immortal Peak to such an extent, let alone support such a terrifying City-Guarding Grand Formation.
Where is that broken sword now?
Zhang Yu asked.
The three old men exchanged glances, and the one in the middle raised his hand, pointing towards the depths of the cave:
"It's right there."
Zhang Yu looked in that direction.
Deep within the cave, on an ancient stone platform, lay a broken sword, dark red in color, covered in cracks, and missing its tip.
The fierce Sword Intent from the broken sword as if it were a tangible force, shattering the surrounding space into fragments, and faintly revealing terrifying phenomena such as a churning Sea of Blood and the wailing of countless souls.
It is indeed—half of the Immortal Exterminating Immortal Sword!
Zhang Yu slowly stepped forward and came to the broken sword.
He raised his hand and gently placed it on the hilt of the sword.
"No!"
The three Progenitor of the Li Family exclaimed in surprise when they saw Zhang Yu about to take the broken sword.
They had witnessed the power of that broken sword firsthand and were worried that Zhang Yu might be reckless and get injured by the Exterminating Immortal Sword.
But as they were speaking, Zhang Yu had already grasped the hilt of the Exterminating Immortal Sword.
"Danger! Let go!"
The elderly man in the middle continued to exclaim in surprise.
