Eternal Pill Emperor

A violent aura burst out from the uninvited guest's body, crushing towards Gu Xuan.    

Gu Xuan didn't immediately launch a counterattack. Instead, he allowed the Qi to hit his body, as if he didn't take it seriously.    

Gu Xuan and the Xiao Ou were speechless.    

The man in front of them was a human-shaped undead spirit. He was as thin as a stick. In his eye sockets, there weren't normal eyes, but two balls of ghostly fire.    

His appearance was indeed frightening, but his cultivation base was only at the peak Holy Monarch Stage.    

An undead spirit like this, where did its courage come from? How dare it show itself? And why was it so confident?    

Gu Xuan shook his head. It was a Qi that belonged solely to the consummate level. When it was unleashed, it was full of pressure. It easily shattered the Qi of the human-shaped undead.    

The human-shaped undead did not even have time to react. It felt that its Qi had collapsed without any warning.    

Following which, a terrifying pressure descended upon its head.    

Dong.    

The human-shaped Undead knelt on the ground and trembled in fear.    

"Great. . . Great Circle!"    

He knew that he had kicked an iron plate, and he was filled with regret.    

"Please spare my life, my lord. I was blinded for a moment just now, so I spoke nonsense. My lord, please don't kill. . . "    

Before the human-shaped undead could finish its words, it saw a ball of black flames flying toward its face.    

Its speed and power were beyond the imagination of the human-shaped undead.    

The human-shaped undead was hit by the black flame before it could react. Its body was burnt into nothingness in an instant.    

"What the hell is this?"    

The Xiao Ou's mouth twitched a few times. That human-shaped undead was really too weak.    

Gu Xuan frowned.    

"We have to speed up. Although this guy is only a peak Holy Monarch Stage undead, he shouldn't be in the outer area of the God Slaughter Tomb. He should be coming from a deeper area.    

Since he has arrived, I'm afraid that the other stronger existences will be arriving soon as well.    

It's even possible that some experts have already arrived, but they have been hiding in the dark all this time and haven't made a move yet.    

After all, there aren't many idiots like this. "    

When the Xiao Ou heard this, the uneasiness in its heart became even more serious.    

"The secondary spirit root has already been fused to the 87th one by the main spirit root. "    

The Xiao Ou seemed to be muttering to itself as it reminded Gu Xuan.    

In reality, even without his reminder, with his current state of mind being connected to Gu Xuan, Gu Xuan could completely sense the thoughts in his heart.    

"Time is too short. There's no other way. . . "    

Gu Xuan took the initiative to stop circulating the Grass Controlling Spirit Art and cut off the connection between him and the Xiao Ou.    

Within the seven-colored vortex, the main and secondary spirit roots that were clearly visible once again became blurry in Gu Xuan's eyes.    

The Xiao Ou's heart skipped a beat.    

"Boss, I think I can still be saved. Why don't you save me?    

Giving up just like that, isn't that your style?"    

The Xiao Ou's voice already carried a sobbing tone.    

His main spiritual root was currently in a damaged state. If he triggered the Heavenly Tribulation later, there was a high chance that the Heavenly Tribulation would find a flaw and cause the tribulation to fail.    

For a Pill Monarch, the significance of the Heavenly Tribulation failing was self-evident.    

Even if he did not die, he would not have the chance to undergo the Medicine Saint's Heavenly Tribulation again in his life.    

Moreover, if he failed once, there would be a shadow in his heart. That would become a nightmare for his entire life. Even if he was extremely lucky and triggered the next Medicine Saint's heavenly tribulation, the probability of failure would still exceed 99%.    

"I'm willing to sacrifice everything. This Medicine Saint Heavenly Tribulation might be the only chance I have in my entire life!    

Boss, you can't give up! "    

The Xiao Ou stared at Gu Xuan. If not for the seven-colored whirlpool revolving around his body, he would probably be lying in front of Gu Xuan now, hugging his thigh and crying.    

Since Gu Xuan stopped circulating the Grass Imperial Spirit Art, he hadn't said anything. Instead, he was calculating the possibility of success in his plan.    

He never would have thought that it would scare the Xiao Ou to such an extent.    

Gu Xuan looked at the Xiao Ou speechlessly, but still did not explain. Instead, he directly took out a handful of Holy Pill. There were a total of five of them!    

For a moment, the fragrance of the Holy Pill filled the air. It made people feel relaxed and relaxed when they smelled it.    

The Xiao Ou's eyes lit up. It finally reacted. Boss did not give up on it.    

Its boss had probably thought of a way to make it swallow those five Holy Pill to restore its main spiritual root.    

This moved the Xiao Ou. Tears nearly flowed out of its mouth.    

The Xiao Ou didn't know that before he woke up, Gu Xuan had already given him three Holy Pill.    

Swoosh!    

The Xiao Ou swallowed its saliva with all its might.    

"Boss, come on. I will use my fastest speed to refine those five Holy Pill. I will cooperate with you!    

You can do whatever you want!"    

The Xiao Ou opened its hands. It looked like it didn't care what you did, and it didn't resist at all.    

A trace of doubt flashed across Gu Xuan's face.    

"What are you doing? Who said that I would give you these five Holy Pill? I'm eating them myself. "    

Gu Xuan opened his mouth and threw the five Holy Pill into his mouth. He swallowed them into his stomach and refined them in an instant.    

A majestic and surging energy erupted within Gu Xuan's body!    

All of the energy was forcefully merged into Gu Xuan's meridians, allowing them to flow along his meridians and surge towards his Dantian.    

The Xiao Ou was dumbfounded.    

Those five Holy Pill were actually not for him?    

Boss, I ate those five Holy Pill?    

"Boss, there are only a dozen over secondary spirit roots left that haven't been fused!    

You actually still have the mood to eat Holy Pill at this time?"    

The Xiao Ou could not understand. What did Gu Xuan want to do?    

Could it be that he had some amazing technique that required him to kowtow five Holy Pill before he could use it?    

That didn't make sense. He, Pill Monarch, was helping him heal his main spiritual root. It wasn't like he was using some sort of forbidden technique to fight, so why would he need to consume a Holy Pill?    

Letting him consume pills was more like it.    

Gu Xuan didn't explain. This was not something that could be explained in a few words.    

He was currently in the midst of a huge gamble!    

The reason he stopped observing the changes in the Xiao Ou spirit root was because there was no longer any need for that.    

Now, it was a situation of internal and external problems.    

Time was too short.    

Continuing to observe, Gu Xuan could not think of a way to restore the main spiritual root in such a short period of time.    

He might as well give it his all.    

What Gu Xuan bet was that the power of the Immortal World could repair the main spiritual root of the Xiao Ou!    

He planned to exchange it for a trace of the power of the Immortal World from the "Paradise Immortal Realm" of the Immortal Token!    

In order to complete this task, he would need his Dantian, which was ten times bigger than his Dantian when he was at the peak Holy Monarch.    

Gu Xuan had already completed half of this prerequisite.    

In Burning Heaven Realm, Gu Xuan had truly advanced to the Great Circle of the Common Grade, and he had obtained a huge amount of Gift of The Heavenly Dao.    

Whether it was his body, soul, or Life Span, all of them had improved tremendously.    

His soul had advanced to the 'complete second tribulation' realm.    

The Life Span, which was originally only 450,000 years old, had now risen to 2,650,000 years old.    

In terms of Life Span alone, it was even better than the great circle of the second tribulation.    

The great circle of the Second Calamity. Under normal circumstances, the publicly acknowledged limit of the Life Span was around 2,400,000 years.    

Of course, these weren't the most important things.    

The most important thing was that Gu Xuan's dantian was still in the process of expanding.    

Back then, the Gift of The Heavenly Dao was too rich. Until now, Gu Xuan had yet to fully digest it.    

According to Gu Xuan's speculation, as long as he digested it, his dantian would be able to increase to ten times its original size.    

However, this process was a little long.    

Therefore, in order to help the Xiao Ou, Gu Xuan had to rely on himself. He used five Holy Pill to forcefully expand his dantian.    

His Dantian had already expanded by five times compared to before.    

In other words, with the size of his Dantian, he only needed to expand it by one fold, and he would be able to obtain a trace of the Immortal World's energy!    

"Let's begin!"    

Gu Xuan circulated the violent energy from the Holy Pill in his body and started to attack the edge of his Dantian.    

The effect was immediate.    

His dantian began to expand at an extremely fast speed. Soon, it expanded by a fifth.    

As the dantian forcefully expanded, what followed was naturally pain, a pain that came from the soul!    

Even with Gu Xuan's strong will, he couldn't help but let out a muffled groan.    

To forcefully expand his Dantian, not only did he have to endure the pain, but he also had to remain clear-headed at all times. He couldn't afford to make any mistakes.    

Otherwise, his Dantian would very likely be torn apart.    

Even if it was just a crack, it would cause the energy within his dantian to flow out for thousands of miles, and he would no longer be able to store energy.    

Therefore, he had to be extremely careful. He had to be extremely careful.    

However, at this critical moment where no one was allowed to disturb them, a total of ten perfection-stage undead appeared from a secret place a hundred miles away. They transformed into Light of Escape and approached!
