Eternal Pill Emperor

Gu Xuan looked at the two Giant Tree in front of him, as if he had regarded them as Saint Qiongpa and the Pagoda Master. With a low shout, he rushed forward.    

Two vines extended out and pierced deeply into the trunk of the two Giant Tree.    

The two Giant Tree withered at a speed visible to the naked eye.    

In a moment, all the leaves on the tree had turned into yellow leaves.    

With a gust of wind, yellow leaves fell from the sky.    

Just like that, a day and night passed.    

Half of the trees in this forest had been harmed by Gu Xuan.    

In the beginning, the process of Gu Xuan absorbing the energy of the trees was still very slow, but as his strength continued to recover, he absorbed it faster and faster.    

At the beginning, absorbing half of the energy of the trees would take a day and a night.    

However, Gu Xuan only used two hours to absorb the remaining half of the trees.    

If one were to calculate carefully, it would take one day and two hours for Gu Xuan to destroy tens of thousands of trees.    

As for the precise number, it could no longer be tested. Even Gu Xuan could not remember it.    

It could not be helped. Absorbing the energy of the trees was an extremely boring process. Therefore, Gu Xuan only allocated a small portion of his spirit to carry it out.    

Gu Xuan used even more of his energy to deduce and study the Azure Wood Longevity Technique.    

This Azure Wood Immortal Technique was a technique that Gu Xuan had obtained when he was still weak.    

This technique had a total of six layers of heaven.    

If one cultivated to the first layer of heaven, the Life Span could increase by twenty thousand years.    

If one cultivated to the Second Heaven, the Life Span would increase by forty thousand years.    

And so on. Every time one cultivated to the First Heaven, the Life Span would double the previous First Heaven.    

When one cultivated to the Sixth Heaven, the Life Span would increase by 640,000 years.    

In other words, after cultivating all of the Azure Wood Longevity Skill's sixth level, the Life Span could increase by a total of 126 million years!    

This was an extremely attractive number to an ordinary Martial Cultivator.    

Unfortunately, Gu Xuan was not an ordinary Martial Cultivator.    

This skill wasn't very attractive to him.    

Firstly, he was still young.    

Secondly, this cultivation technique wasn't very effective in battle.    

Thirdly, he had too many opportunities and choices. He didn't want to spend too much time studying a cultivation technique that didn't have a strong combat strength.    

Of course, at the beginning, he still spent a lot of effort on cultivating this mystical technique that could increase the strength of the Life Span.    

However, as his strength increased at a rapid rate, he felt that this cultivation technique seemed to be of little value to him. It was not cost-effective.    

Hence, after Gu Xuan finished cultivating the Azure Wood Longevity Technique's Third Heaven, he gave up on cultivating it.    

No matter how small a mosquito's leg was, it was still meat.    

However, when it took a lot of energy to obtain this mosquito leg, Gu Xuan, who had always been in a hurry, had to consider whether it was worth it or not.    

The Green Wood Longevity Technique corresponded to the difficulty of cultivating the Life Span.    

Every time he finished cultivating the first level, the difficulty of cultivating the second level would increase by several times.    

In fact, compared to the third level, the difficulty of cultivating the fourth level increased by more than ten times. It could be said that there was a qualitative change.    

Hence, Gu Xuan gave up when he first cultivated to the third level.    

With his strength at that time, he had calculated that he would need at least a year of seclusion to cultivate to the Fourth Heaven.    

To Gu Xuan who was over a hundred years ago, a year's time was simply too long.    

Besides a long period of time, he also needed to consume the purest Wood Type Power to cultivate this skill.    

Although the general outline of the cultivation technique was not explicitly stated, according to Gu Xuan's deduction, the Wood Type Power required to cultivate to the Sixth Heaven was already very close to the Wood Element Power of Origin.    

Even the current Gu Xuan had difficulty converting this kind of energy through his Dantian.    

He could only rely on the outside world to absorb it from the outside, or use medicinal pills to provide it.    

This was also one of the reasons why Gu Xuan gave up on cultivating this cultivation technique.    

Of course, it seemed like all of this was due to prejudice.    

And now, these prejudices had become a thing of the past.    

Ever since Gu Xuan had a fortuitous encounter in the Space Ring of the Soaring Demon God, Gu Xuan had once again attached great importance to this cultivation technique.    

The Bookworm who had lived for countless tens of thousands of years was extremely shocked by the fact that Gu Xuan had cultivated the Azure Wood Longevity Technique.    

Therefore, Gu Xuan was certain that there was a secret hidden within the Azure Wood Longevity Technique.    

However, Gu Xuan had no idea what the secret was.    

However, after a day and two hours of continuous deduction of the Green Wood Longevity Skill, Gu Xuan finally had some clues.    

"On the surface, this cultivation technique only appears to be at the Sixth Heavenly Layer.    

However, there was still room for improvement in the cultivation technique of the Sixth Heavenly Layer. It hadn't pushed the cultivation technique to its peak yet.    

According to the cultivation of the Law of Incantation, it still has the same feeling of laying the foundation, as if it was laying the foundation for something! "    

Gu Xuan mumbled to himself. His eyes were glowing brightly.    

"This feeling is very uncoordinated.    

A complete and mature cultivation technique should be able to let people see its limits.    

Moreover, even if there are flaws, it shouldn't make people feel that it is uncoordinated.    

Hence, this cultivation technique was not just Level Six, it was very likely that there was also Level Seven!    

However, one needs to cultivate to the Sixth Heaven to reveal the clues!"    

Gu Xuan came to a conclusion. He increasingly felt that he needed to start cultivating this cultivation technique as soon as possible.    

He had already finished cultivating the first three Heavenly Layers. Now, he only needed to start from the Fourth Heavenly Layer.    

Gu Xuan was confident that as long as he had enough Wood Type Power, he would be able to cultivate the Fourth Heavens within three days.    

More than a hundred years ago, with Gu Xuan's current strength, he was confident that he would be able to cultivate the Fourth Heaven within a year.    

More than a hundred years later, he would only need three days. This was very reasonable.    

"Unfortunately, after absorbing the Wood Type Power from the tens of thousands of tall Giant Tree in the forest, my strength has only recovered by thirty percent.    

The Soul Power has only recovered thirty percent of my strength, and there are still some injuries to my soul, so I need to recuperate.    

The energy in my Dantian can only be used to protect myself. I really can't use it to cultivate the Green Wood Longevity Technique."    

Gu Xuan felt a little regretful.    

"Let's go out of the forest and see what's happening around us.    

I am now in the territory of the Seven Stars Realm's Realm Heart. There are dangers everywhere, and I need to be at my wits' end."    

Gu Xuan had already determined the direction he was heading in, and soon, he arrived at the edge of the forest.    

Outside, there was a hilly area.    

Gu Xuan had been in the forest for a long time. He had already confirmed the peak of the highest Giant Tree. After passing through the hilly area, he would be able to enter a grassland.    

The castle that was full of guards was on the grassland.    

That Weak Water river was also on the grassland!    

"If I want to return to the Burning Heaven Realm's territory, I must go to that grassland!"    

Gu Xuan's footsteps were very firm.    

Unfortunately, this firm footsteps stopped after Gu Xuan walked out of the forest.    

In the distance, on the nearest hill, a familiar figure suddenly appeared.    

The person who suddenly appeared also noticed Gu Xuan.    

Gu Xuan's pupils constricted, and the corners of his mouth twitched violently.    

This... this was really a bad fate!    

"Damn it, it's you, Demon God Teng!    

Even you want to kill me? You even circled in front of me to intercept me!    

Very well, there are pursuers behind me, and there is an ambush in front of me. This is truly a hopeless situation.    

Unfortunately, this isn't the first time that I, Evil Ancestor, have encountered such a hopeless situation. Furthermore, this time, I won't be the one to die!"    

The person who had suddenly appeared on the hill was none other than Shi Zhixuan!    

His footsteps were light, and it was obvious that he had suffered a serious injury. However, the evil smile on his face didn't diminish in the slightest.    

Swoosh!    

He rushed down the hill and rushed towards Gu Xuan!    

"Die, Demon God Teng!"    

Shi Zhixuan roared. His speed was extremely fast. In a moment, he had arrived in front of Gu Xuan!    

His fists, which were like a violent storm, came at ___!
