Standing next to Nie Tian, Pei Qiqi noticed that there seemed to be something wrong with him, and thus asked concernedly, "What's wrong, Nie Tian?"
Nie Tian shook his head. "No, I'm fine. Don't worry. I just need to check something."
His psychic awareness swam inside that refined fragmentary star mark, through which he discovered that he could actually control the grand star formation over the mouth of the spatial rift.
As a thought appeared in his mind, the grand star formation formed by countless detailed patterns started to shine with dazzling, bright starlight.
An ancient, boundless aura was gradually unleashed from within the grand star formation.
Then, Nie Tian discovered that his seven Heaven Eyes, which he had scattered in the vicinity, rapidly converged on the spatial rift and flew into it in the next moment.
SHEW! SHEW! SHEW!
As they did, a streak of glorious starlight flew into each of his seven Heaven Eyes.
After being infused with starlight, the Heaven Eyes, which could only detect living beings with the puny amounts of soul power in them, suddenly turned into dazzling stars.
They shone brightly and became visible to the naked eye.
Now, floating in the dim spatial tunnel, Nie Tian's Heaven Eyes morphed into seven shining fragmented stars, through which, he noticed that the battle between Hua Mu and the Rotspirit Ox was still going on.
The Rotspirit Ox's howls echoed out from within the dense swirling demon Qi from time to time.
Meanwhile, Nie Tian noticed that his Heaven Eyes seemed to have been infused with a mysterious power when they passed through the grand star formation at the mouth of the spatial rift, enhancing their perception by dozens of times.
However, he realized that the substantialization of his Heaven Eyes and the sudden boost in their perception must only be temporary.
Even still, he was deeply shocked by the monstrous enhancement.
It wasn't long before he sensed danger via those Heaven Eyes.
He sensed that a few vigorous auras that terrified his very soul were coming at extremely fast speeds from a very distant location in the spatial tunnel, following the misty rivers of demon Qi.
He could even vaguely hear their rapid panting.
All of a sudden, he was struck by a mysterious feeling.
As a thought appeared in his mind, he discovered that the wisp of his soul power within one of his Heaven Eyes had begun to expand and morph.
Immediately afterwards, Nie Tian's soul shadow appeared within that glittering Heaven Eye.
Hua Mu, who was fighting the Rotspirit Ox, detected the strange cluster of bright starlight, and thus asked tentatively, "Nie Tian??"
The cry of Nie Tian's soul echoed out from within that glittering Heaven Eye, mixed with a buzzing sound, "Uncle Hua! Stop fighting that Rotspirit Ox! Many more powerful Demons are coming at us now!"
"Exactly as I expected! This Rotspirit Ox is only a bait! High-tier Demons must have learned about what happened in the Realm of Flame Heaven, and they are now marching here!" Hua Mu didn't doubt the authenticity of Nie Tian's words in the slightest. Submerged in the misty dense demon Qi, he let out a cold harrumph as he turned into a cluster of green flames and shot out of there.
As he did, some of the green flames sputtered and fell on the Rotspirit Ox's body.
The Rotspirit Ox let out agonized wails as its enormous figure could be vaguely seen twitching within the raging demon Qi.
At that moment, with a thought, Nie Tian established a subtle connection with the grand star formation.
In the next moment, beams of dazzling starlight shot out from the brilliant star formation within the rotating gray vortex and shone upon the swirling demon Qi.
The rich, swirling demon Qi rapidly dissipated like a snowball being melted by heat.
As that happened, the enormous Rotspirit Ox gradually appeared in front of Nie Tian's Heaven Eyes.
The battle between it and Hua Mu hadn't gone on very long, yet the Demon was already covered in wounds.
Via his Heaven Eyes, Nie Tian observed it closely and discovered that its metal-solid scales had fallen off many parts of its body.
Demonic blood kept flowing out of the messy, exposed flesh and staggering gashes.
Fuming with wrath, the Rotspirit Ox roared unceasingly. However, deep fear could be seen in its glittering eyes.
Apparently, this sixth grade Demon, whose strength matched up to that of a late Worldly realm human Qi warrior, was no match for Hua Mu.
The reason why Hua Mu had dared to stay and fight it single-handedly was that he had enough confidence in his own battle prowess.
Beams of starlight continued to scatter and dissipate the demon Qi around the Rotspirit Ox.
Seeing the incoming beams of starlight, the Rotspirit Ox's enormous body squirmed about as it seemed more scared now than when it had faced Hua Mu.
It appeared to know how powerful those beams of starlight were, and thus hastily backed away, leaving the demon Qi, which could heal its wounds and recover its strength.
The rivers of demon Qi also seemed to rapidly unravel after being illuminated by the starlight.
On the other end of the rivers of demon Qi, a few blurry figures were quickly approaching.
Due to the exceedingly long distance, even Hua Mu wasn't able to detect them.
However, Nie Tian managed to sense their aura and images via his seven Heaven Eyes.
After a while, the rivers of demon Qi that the figures had been traveling along suddenly came to an end.
A large part of the rivers of demon Qi, which had originated from the Sixth Demon Realm, had been burnt away by the starlight.
The few figures stopped and stood at the point where the rivers of demon Qi ended.
Nie Tian managed to obtain a clear view of the figures via his strengthened Heaven Eyes.
"Caro! Zelia!" Nie Tian recognized two of them. They were the two high-tier Demons who had led the invasion of the Realm of Flame Heaven.
Caro was the one who had single-handedly dealt with Chang Sen, the most powerful Qi warrior in the Realm of Flame Heaven.
At this moment, however, Caro was whispering something to another tall Demon in a very respectful manner.
Standing behind the handful of noble high-tier Demons were hundreds of other high-tier Demons, and standing behind them was an army of low-tier Demons that stretched as far as Nie Tian could see, looking like an endless swarm of flies.
Due to the excessively long distance, this was all Nie Tian could see via his Heaven Eyes.
"A large Demon army is coming!" Nie Tian's muffled voice rang out from one of his Heaven Eyes.
"You can see them?!" Hua Mu exclaimed.
"Yeah, a very large Demon army is gathered at the point where the rivers of demon Qi end," Nie Tian replied. At the same time, Nie Tian noticed via his Heaven Eyes that the rivers of demon Qi were extending as they were infused with torrential demon Qi pouring from the Demon's realm.
"Return to the Realm of Flame Heaven with me!" Hua Mu said. "The restrictive spell formation left by the Ancient Fragmentary Star Palace should be able to stop them!"
With these words, Hua Mu turned around and flew into the gray vortex like a flash.
Immediately afterwards, Nie Tian retracted his Heaven Eyes from the spatial tunnel.
He let out a long sigh and opened his eyes. Standing by the edge of the spatial rift, he said, "A large Demon army is coming our way. I hope the grand spell formation left by the Ancient Fragmentary Star Palace will be able to block them off."
At that moment, Hua Mu appeared by his side and asked hastily, "Have those three fragmentary star marks returned to you, Nie Tian?"
"Yeah, they came back and merged with my body again," Nie Tian said.
"Okay, that means the grand spell formation is already fully activated. Even without the fragmentary star marks, it will be able to operate fine on its own." After a moment of silent pondering, Hua Mu added, "That being the case, your job is finished here in the Realm of Flame Heaven. Huang Fan, you should take him to the Realm of Mystic Heaven and the Realm of a Thousand Devastations now. They need him more than we do."
Surprised, Huang Fan said, "Alright."
For some reason, he subconsciously obeyed Hua Mu, even though he still couldn't figure out who Hua Mu really was.
Hua Mu waved his hand at Nie Tian and beckoned for him to leave. "You go first. I'll stay and look after things in the Realm of Flame Heaven. Rest assured. Now that the fragmentary star marks have returned to you, it means your job here is finished. Don't you worry about a thing in the Realm of Flame Heaven. The Realm of Mystic Heaven and the Realm of a Thousand Devastations now need you more than ever."
