The message from Fan Cheng informed him that near the Monster Beast Mountain, he saw dark clouds gathering in the sky, with lightning occasionally flashing, creating a scene of impending doom.
Within the Monster Beast Mountain, lower-level demon beasts had all fled in fear, leaving only a few demon king-level beasts still on the mountain.
After reading the message, Xu Mo was certain this was the tribulation to ascend to Sainthood!
"It's like when you're sleepy, and someone hands you a pillow!" he mused, feeling a sense of fortune. If he could refine another wave of Seven Tribulation Heavenly Lightning, he would surely enter the Great Sage stage.
And according to Xu Mo's estimation, the old Demon Emperor would definitely encounter the Seven Tribulation Heavenly Lightning.
This was because the old Demon Emperor himself was extraordinary. While not as gifted as Bai Yue, who seemed to have a cheat, he had steadily built a very solid foundation.
Encountering the Seven Tribulation Heavenly Lightning was practically guaranteed.
If, by some bad luck, he didn't encounter it, Xu Mo had a way to make the old Demon Emperor face it – nothing more than provoking the heavenly tribulation.
Having undergone his Saint Tribulation, Xu Mo understood that there was consciousness controlling the heavenly tribulation from behind, or rather, the heavenly tribulation itself possessed consciousness.
The last time he faced the Nine Tribulation Heavenly Lightning, the consciousness within the tribulation had become enraged, determined to kill him at all costs. However, he had managed to escape by hiding in the Chaos Smelting Furnace.
If he were to provoke the heavenly tribulation during the old Demon Emperor's tribulation this time, that consciousness would likely descend again.
These were merely Xu Mo's thoughts; the old Demon Emperor would most likely encounter the Seven Tribulation Heavenly Lightning anyway.
Without dwelling on it further, Xu Mo set off immediately, leaving the Imperial Capital and heading towards the Great Barrens Western Region!
Half an hour later, Xu Mo appeared in the Great Barrens Western Region, at the Monster Beast Mountain!
The Great Barrens Western Region was unlike the Eastern or Northern Regions. There was no human habitation here, only demon beasts. The terrain was also not like the Eastern Region, which was mostly plains, but rather a continuous expanse of peaks and dense forests.
Only such terrain was suitable for demon beasts to survive.
The Monster Beast Mountain was the center of the Western Region, not referring to a single peak, but rather the entire mountainous area, all known as the Monster Beast Mountain.
Ninety percent of the demon beasts in the Western Region resided here, obeying the old Demon Emperor's command. Therefore, the Monster Beast Mountain was also called the Land of Ten Thousand Demons!
Fan Cheng was hidden on a low-lying peak. Xu Mo, guided by the sense of the Tribulation Crossing Seal, found Fan Cheng directly.
"Your Majesty, you came so quickly?" Fan Cheng's expression was one of immense surprise upon seeing Xu Mo.
He had only sent the message less than half an hour ago, and His Majesty had already arrived in person. It seemed His Majesty attached great importance to the commotion at the Monster Beast Mountain!
"Mm," Xu Mo nodded, then turned his gaze towards the sky above the Monster Beast Mountain in the distance.
It was already covered in dense, dark clouds, with lightning spreading within them, creating a very oppressive atmosphere.
His spiritual power probed the area. Most of the demon beasts in the Monster Beast Mountain had already left, with only three demon kings remaining to guard. Judging by their stance, they were likely preparing to protect the old Demon Emperor during his tribulation.
The overall situation was largely consistent with what Fan Cheng had reported.
Fan Cheng spoke up, "Your Majesty, why is there such a situation in the Monster Beast Mountain? Could it be that that old Demon Emperor is about to undergo some tribulation?"
He was filled with doubt. Beasts below the Saint realm did not need to undergo tribulations. Therefore, he was quite unfamiliar with heavenly tribulations, having only encountered them in ancient texts.
Xu Mo nodded, not concealing anything, "That's right, it's the old Demon Emperor about to undergo his Saint Tribulation."
"Undergo... Saint Tribulation!?"
Fan Cheng's eyes widened, his heart filled with disbelief!
"The old Demon Emperor is at the Quasi-Saint realm, and now he's undergoing his Saint Tribulation to become a Saint!?"
He gasped, finding it incredibly terrifying.
Saints were the supreme existences in the Great Barrens, previously only existing in legends. Was he about to witness the birth of a Saint with his own eyes?
For a moment, Fan Cheng's emotions were complex. He had not yet broken through to the Divine Rope realm, and beyond that were the Heaven-Treading realm and the Quasi-Saint realm. He was too far, far away from becoming a Saint.
Soon, Fan Cheng became worried again. If the old Demon Emperor became a Saint, wouldn't that pose a threat to the Great Gan?
Xu Mo saw Fan Cheng's concern and smiled, "Don't worry, he's only just broken through to Sainthood. He's no match for me!"
Just yesterday, he had crushed a Saint on Earth. Newly ascended Saints were indeed nothing in his eyes.
Hearing His Majesty's domineering words, Fan Cheng's blood surged, and he felt relieved.
That's right, with His Majesty here, there was no need to worry even if the old Demon Emperor broke through to Sainthood.
Fan Cheng already knew that His Majesty had achieved Sainthood, and he believed in His Majesty completely, because His Majesty never lied!
"Your Majesty, you sent this subordinate to monitor the situation. Did you foresee the old Demon Emperor undergoing his Saint Tribulation and plan to interrupt him, causing him to fail?" Fan Cheng suddenly asked with excitement.
He felt that he might have guessed His Majesty's intentions. If not, why would His Majesty send him to monitor the Monster Beast Mountain?
"No, I would not stoop to such underhanded sneak attacks," Xu Mo shook his head.
Fan Cheng was taken aback, not expecting His Majesty to say that. If that were the case, what exactly was His Majesty planning to do?
Xu Mo didn't say much, merely telling Fan Cheng to watch.
He had already sensed the old Demon Emperor's appearance.
And the moment the old Demon Emperor appeared, the dark clouds in the sky instantly began to churn, like a dark sea, surging and rolling.
Thunder roared, and bolts of lightning, like sea dragons, thrashed within the dark sea of clouds, creating a magnificent spectacle!
With a deafening 'boom,' the heavenly tribulation began to descend, striking the old Demon Emperor directly, blasting off pieces of flesh and blood.
Fan Cheng trembled all over after just one glance.
The Saint Tribulation was terrifyingly powerful. The aura carried by the lightning was something that cultivators of his realm could not possibly resist.
Even a small spark of electricity that leaked out could heavily injure him.
Xu Mo waved his hand, erecting a barrier in front of Fan Cheng, blocking the terrifying aura of the heavenly tribulation.
Fan Cheng quickly thanked His Majesty.
"Stay here and don't wander off. The heavenly tribulation grows stronger as it progresses!" Xu Mo said, then stepped forward, approaching the old Demon Emperor who was undergoing his tribulation.
As soon as they neared the Monster Beast Mountain, the three demon kings who were protecting the old Demon Emperor saw Xu Mo and immediately moved to intercept him.
Xu Mo merely glanced at the three demons. He released a sliver of his Saintly aura, and the three demon kings instantly collapsed in fear, losing their ability to resist.
The old Demon Emperor also sensed Xu Mo's approach, and his expression immediately tensed!
The Emperor of Gan? What was his intention in coming to the Monster Beast Mountain at this time?
Was he planning to take advantage of his Saint Tribulation to attack him?
The old Demon Emperor panicked, but he was in the midst of his tribulation and could do nothing. He could only question Xu Mo, "Emperor of Gan, what is the meaning of this?"
As soon as he finished speaking, the second wave of heavenly tribulation descended, forcing him to grit his teeth and continue enduring it.
Xu Mo looked at the old Demon Emperor and replied with a smile, "Old Demon Emperor, if I said I was here to help you through your tribulation, would you believe me?"
