The comet remained silent, only relentlessly unleashing heavenly tribulations.

Without even looking, Song Yi swung his axe in a backhand motion, cleaving the plague pythons in half at the waist. The whip was also sent flying backward by the impact. Yang Wenhui staggered back several steps before regaining his balance, his arm holding the whip trembling slightly.

Chen Geng's Plague Killing Array had now shrunk to a radius of ten zhang. The four-colored plague energy had actually condensed into four poison swords of different colors, which hung in the four directions, with their tips all pointing at Song Yi, emitting a chilling light that made people's hair stand on end.

A glint flashed in Song Yi's eyes, and the merits of humanity within him surged into the stone axe like a river bursting its banks. The stone axe emitted a long, buzzing sound, and a warm yet unbearable golden light shone on its blade.

That is the radiance of humanity, the collective power of all people, which makes it impervious to all evil and ward off all poisons!

He leaped up, his body and axe becoming one, transforming into a golden axe beam that tore through the sky, slashing fiercely at the Plague Killing Array!

"Break it!"

boom!

Amidst a deafening roar, the four poisonous swords shattered simultaneously, and the Plague Killing Array crumbled like glass falling to the ground.

The innate plague umbrella in Chen Geng's hand was struck head-on by the axe's edge. The plague light flowing on the umbrella surface dimmed instantly, the umbrella ribs groaned under the strain, and the cloth was torn in several hideous rips, becoming tattered and unable to gather plague energy anymore.

He himself let out a miserable cry, his Dharma form was injured, and a mouthful of emerald green life-bound blood spurted out a long distance, his body flying backward like a kite with a broken string.

At this moment, the four Plague Gods' magical artifacts were shaken, and their divine forms were damaged to varying degrees. Their faces were ashen, and the plague energy around them was scattered and unstable.

The four looked at each other in horror, disregarding all decorum, and dragging their tattered umbrellas, chimes, banners, and whips, they transformed into four dim gray lights and fled into the Plague Palace.

"Now, it seems we're truly locked in a life-or-death struggle with the Plague Tribe."

Looking in the direction where the four plague gods fled in a sorry state, Song Yi sighed, but there was no regret in his tone.

If the Qingtianjian (the Imperial Observatory) wanted to truly rise to power, it would inevitably clash with the interests of various parties, making enemies and creating enmity.

He then stopped thinking about it and seized the time to continue his work, opening up thousands of miles of waterways in Taihuan Jiyaotian.

In ordinary heavens, it would take tens of thousands of miles of rivers to complete the task, but in this urgent situation, he had no intention of reshaping the ecology of this heavenly region. A shallower and shorter river would save him more trouble.

Just as they broke through the passage from Taihuan Jiyao Heaven to the fifteenth level Xuanming Gongqing Heaven, they saw the Plague Emperor Lü Yue flying down from the lower realm.

"The Broom Star Lord is incredibly lucky; he even managed to get his hands on Emperor Yu's axe!"

Lü Yue's voice was sinister, carrying a chilling undertone.

"Emperor Yu was benevolent and favored only minor deities."

Song Yi remained unmoved, then bowed respectfully and said, "There was a slight misunderstanding with the gods of the Plague Department when we were digging the river. If there was any offense, I hope Your Majesty will forgive me."

"It's alright." Lü Yue's face was ashen as he slowly said, "I underestimated you. If you had been born in the ancient primordial era, you would surely have been a great figure."

"Your Majesty is too kind." Song Yi's expression remained gentle and his tone calm. "Thanks to Your Majesty's great fortune, the river channel of Taihuan Jiyao Heaven has been completed. This humble god will now take his leave."

Having said that, he didn't even look at Lü Yue's increasingly ugly face, and headed straight for the fifteenth level, Xuanming Gongqing Heaven.

In the days that followed, Song Yi used both the power of the axe and the labor of digging, employing a two-pronged approach that resulted in a surge in efficiency.

In less than a century, the river was completed, leading all the way to the first day, the Taihuang Huangzeng Heaven, which is also known as the "Great Prison Heaven" by the immortals.

"Brother Song, that's incredibly fast!"

The Giant Spirit clicked his tongue in admiration, then patted his chest and said, "Once I gather nine thousand Imperial Guards, I'll help you dig through the Great Luo Heaven in one fell swoop!"

"Why bother the general with such trouble?" Song Yi quickly declined.

"Those kids are just idling around all day anyway, might as well take them out for a spin." The Giant Spirit waved his hand dismissively.

Song Yi didn't accept the politeness. Instead, he cupped his hands and smiled, "General, there's no need for such formalities. Between us, we can speak frankly. As long as it's within my power, I will certainly not refuse."

"As expected, nothing could hide it from the Star Lord."

The Giant Spirit laughed, then lowered his voice and said, "I've heard that Emperor Yu's axe is in the hands of the Star Lord?"

Song Yi nodded, then said, "General, do you perhaps intend to use this axe?"

"Yes and no," the Giant Spirit God said solemnly. "How can an ordinary person use the sacred artifact of Emperor Yu? This time, I would like to ask the Star Lord to personally wield Emperor Yu's Mountain-Splitting Axe to deal with a prisoner and take a few drops of his essence blood."

"What kind of prisoner requires the use of Emperor Yu's axe to split mountains?" Song Yi's heart skipped a beat. "Could it be that Great Sage of the North Sea Underworld?"

"No."

The giant spirit slowly shook his head and said, word by word, "To be precise, that was not a living prisoner, but a head."

Song Yi was taken aback at first, then his pupils shrank sharply, and he said incredulously, "What the general is talking about... could it be the head of Xing Tian?"

"Indeed." The giant spirit nodded slowly.

Song Yi couldn't help but gasp, and for a moment he was speechless.

In ancient times, Xing Tian was one of the strongest beings below the Ancestral Witches, and was as famous as Jiu Feng and Chi You.

Legend has it that after the Lich War, he devoured some of the ancestral witch's essence and blood, thus reaching a higher level. Although he is not yet on par with top ancestral witches like Xuanming and Zhujiuyin, he is already comparable to the likes of Qiangliang, Shebishi, Tianwu, and Yanzi.

What's even more terrifying is that Xing Tian understands a wisp of the true meaning of the Heaven-Opening Axe of the Father God Pangu, far surpassing the likes of Wu Gang.

For this reason, in ancient times he wielded a giant axe and shield and stormed the Heavenly Court, actually injuring the physical body of the Jade Emperor.

However, the Jade Emperor, with supreme power, severed its head with the Jade Sword.

However, because the shield and axe contained the true meaning of Pangu's creation of the world, the Jade Emperor was forced to undergo reincarnation and tribulations. He experienced 1,750 tribulations in the human world, each of which was a period of time, lasting for 129,600 years, until the time of Xia Qi, when he finally ascended to the throne of the Heavenly Emperor and ruled over all the spirits in the heavens.

"Xingtian's head has been suppressed in the seventy-seventh level of the Heavenly Prison," the Giant Spirit God said in a deep voice. "The body of a Great Witch is immortal and indestructible. Xingtian is even more extraordinary, with a physical body that is almost indestructible. In the world, only sacred artifacts containing the luck of humanity, such as the Xuanyuan Sword and the Yu Emperor's Mountain-Splitting Axe, can break his body."

Song Yi frowned slightly, somewhat puzzled: "General, you are not listed on the Investiture of the Gods, so you are not bound by any rules and can cultivate on your own. Moreover, you are cultivating the orthodox Xuanmen sect. Why then do you need Xing Tian's essence blood?"

The Giant Spirit sighed, a hint of resentment in his eyes: "I have been stuck at the peak of the Profound Immortal realm for tens of thousands of years, unable to make any progress. If I could observe the essence blood of the Great Witch and comprehend that wisp of immortal true meaning within it, perhaps I could take the opportunity to break through the bottleneck and step into the Golden Immortal realm."

Seeing that Song Yi was still hesitant, he whispered again, "Star Lord is a Yin God from the Investiture of the Gods. Although he has a golden body, he is ultimately not a flesh and blood being. If he could obtain the essence blood of someone like Xing Tian, ​​who is comparable to an Ancestral Witch, he might be able to use it to evolve a flesh and blood body. Star Lord should understand the benefits."
