"Immortal Emperor Sword, if you go to the Heavenly Realm. I will definitely find you, and I will refine you. A moment later, an angry voice came from the infinite distance of time and space.

"Hmph! When I get to the Heavenly Realm, I will definitely kill you. Immortal Emperor Sword snorted coldly and said.

I don't know how long it took, Zhao Yu suddenly felt that the immortal power in his body began to increase endlessly, which almost made his body unbearable. His divine consciousness was also rapidly improving, and some of the divine consciousness of the celestial envoy clone had also been refined.

Even if he is a clone of the Heavenly Realm Envoy, the terrifying immortal power contained in his body is not something that a powerhouse in the Void Immortal Realm can refine. If it weren't for Zhao Yu refining a few fragments of the Chaos Immortal Weapon, making his body extremely strong, I'm afraid his body would be able to hold up. Even if you don't die, you will be seriously injured.

Half a month later, Zhao Yu finally completely refined a clone of the Heavenly Realm Envoy. Xiuwei also broke through to the first-level true immortal realm.

At this time, his body trembled slightly, and the slightest fluctuation of immortal power emanating from it in an instant caused the void within a radius of thousands of miles to tremble violently.

Due to the fact that the divine consciousness of this celestial envoy clone contained some laws of time and space, Zhao Yu's comprehension of the laws of time and space had also improved several realms.

After Zhao Yu stepped into the True Immortal Realm, he could absorb the amazing heaven and earth aura from the endless void, and he could also absorb some immortal qi from the heavenly realm. His longevity has also skyrocketed tenfold.

"Hahaha! My cultivation has actually broken through the first-level True Immortal Realm, and my longevity has exceeded a million years. Now my strength can fight with Yang Zhi, the Holy Lord of the Purple Cloud Holy Mountain, and the Sect Master of the East and West Demon Sect. Zhao Yu was extremely ecstatic in his heart.

"At the beginning, the sect master of the West Demon Sect was a well-known demon supreme, shocking the eons and treating me as an ant, but now, I am also pressing him to fight. I'll go and seize the Heavenly Demon Book in his hand now!" After a while, Zhao Yu suddenly said to the Immortal Emperor Sword.

"Okay! The Heavenly Demon Book, which was originally the Book of the Immortal Emperor, fell into the hands of the Demon Clan a long time ago, and now I will join forces with you to take it back as soon as possible. Hearing this, Immortal Emperor Jian smiled slightly and said.

Although the sect master of the West Demon Sect has been in retreat and penance cultivation over the years, and his cultivation has broken through two realms one after another, his strength is only in the Void Immortal Realm, and in the face of Zhao Yu's first-level True Immortal Realm's strength, he is not an opponent at all.

Even if he had the Heavenly Demon Book, as long as Zhao Yu urged the Tianhe Diagram with all his might, he could sweep him away.

Now that the Immortal Emperor Sword has also returned, he and Zhao Yu have joined forces to easily crush the Sect Master of the Western Demon Sect.

"The Sect Master of the Western Demon Sect has a Heavenly Demon Book, which can be used to deduce many things in the future, and it may be difficult for us to find him. Immortal Emperor Sword suddenly reminded.

"Zhao Yu, I just got a top-secret news that those demons have all disappeared in the Vega Star Domain. Half an hour later, Liu Yuting's voice passed through the layers of spatial barriers and entered Zhao Yu's divine consciousness.

"What? The demons have all disappeared, it seems that they have left the Vega Star Domain? Maybe they also know that the primeval god tribulation is coming. When Zhao Yu heard this, his heart suddenly trembled.

"Zhao Yu, the news of the Ancient God Tribulation has already spread throughout the Vega Star Domain, and even many immortal cultivation sects are all ready to move. Some of the sect masters and elders of the Minor Immortal Cultivation Sect had already left their disciples behind and were fleeing towards other star fields. A moment later, Liu Yuting's voice came again.

"In fact, even if these people flee into other star fields, it is useless, the army of the Ancient God Clan will sweep through thousands of star fields in the Nether Realm this time. If we stay in the Vega Star Domain, there may be a glimmer of life, and once the Ancient God Tribulation is over, as long as some of us can survive, we may be able to get a great chance. It is rumored that those who guard this star field will get some star field origins, and their luck will also skyrocket, and their cultivation will advance by leaps and bounds from now on. Therefore, many immortal cultivators will stay in this star field. After a pause, Liu Yuting's voice came again.

Whew!Whew!

Zhao Yu and the Immortal Emperor Sword teleported again and again in the void, and after each teleportation, they could move at least a billion miles away.

After a while, Zhao Yu and the Immortal Emperor Sword found the crack passage to the abyss underground.

Whew!Whew!

Zhao Yu and the Immortal Emperor Sword immediately rushed into the crack passage in the ground, and after a few breaths, they appeared in the first layer of the underground world, which was empty and wild, without the breath of a single demon.

The next moment, they appeared in the first layer of the underground world again, and there was no demon breath there.

As they went deeper and deeper into the ground, the demonic qi there became thicker and thicker, and the demonic qi was mixed with some Nine Shades Qi.

"Zhao Yu, we have gone deep into the tenth layer of the underground world, and further down is the Nine Shadows Abyss. It seems to be a different dimension, and there are some terrifying beings in it. Even the Celestials could not defeat them. At this time, the Tianhe Immortal Spirit suddenly transmitted a voice.

"Immortal Emperor Sword senior, below is the Nine Shadows Abyss!What should we do?" Zhao Yu pondered for a moment, and his divine sense transmitted.

"Zhao Yu, as long as you and I join forces, we can shuttle through the Nine Shadows Abyss. Even those powerful beings may not be able to kill us. The Immortal Emperor Sword immediately transmitted his divine sense.

A moment later, Zhao Yu and the Immortal Emperor Sword flew into the billowing Nine Shadows Qi, which was thousands of miles thick, and they carefully flew away for a full hour before flying out of the barrier of the Nine Shadows Abyss.

The Nine Shadows Abyss was originally the ancestral land of the Demon Race. It is like the surface world is incomparably vast, and thousands of demon races live. But millions of years ago, many demons were driven out of there, and they entered the underground world.

"For countless years, the Immortal Cultivation Sect led by the Purple Cloud Sacred Mountain has joined forces dozens of times to try to wipe out the Underground Demon Clan, and there have been several times when they have entered the Nine Shadows Abyss, but they have all been expelled by some powerful beings inside. Even the primeval gods would not be able to occupy this place. The Immortal Emperor Sword flew away at an extremely fast speed, and at the same time, the divine sense transmitted.

After a cup of tea, Zhao Yu and the Immortal Emperor Sword finally stepped on the ground of the Nine Shadows Abyss. It was full of poisonous demonic energy and evil energy, and all the plants and trees were also very hideous and terrifying, and almost all of them were bloodthirsty.

There is also a lot of space in the Nine Shadows Abyss, Zhao Yu's divine sense can only detect within a hundred miles, even if it is the Immortal Emperor Sword, his divine sense can only detect within a thousand miles.

Along the way, they encountered various Nine Shadow Creatures such as the Dark Wolf, the Dark Leopard, and the Dark Tiger, all of which were swirling with a cloud of Nine Shadow Demon Qi, and their strength was comparable to that of the immortal giants. Some of the more powerful Nine Shadow creatures are comparable in strength to the Void Wonderland.

In the depths of an underground swamp with a radius of 100,000 miles, they discovered a mountain-like Nine Shadows creature, who seemed to be sleeping, absorbing the Nine Shadows Demon Qi in his sleep.

They soon discovered that the strength of this Nine Phantom Creature did not seem to be below the first-level True Immortal Realm.
