Relying on his weak perception of the Sun and Moon Dragon Spring, the Dragon Evil Emperor took Zhang Ruochen to quickly flash in this area and searched carefully.

The large area is filled with the breath of the Sun and Moon Dragon Spring, but no matter how you look, you can't find it at all, as if it is no longer here.

The Sun and Moon Dragon Spring has long been spiritual and knows how to seek good fortune and avoid bad luck. After being born, they will never stay somewhere for a long time.

"Are we a step late?" Dragon Evil Emperor seemed a little unwilling.

It’s a pity that I finally found the traces of the Sun and Moon Dragon Spring.

Zhang Ruochen thought about it, took out the secret scriptures of time and space, mobilized the spatial rules in his body to inject them into it, and suddenly, an invisible spatial fluctuation spread.

This space fluctuation is extremely mysterious, slowly penetrates into the surrounding space and underground, carefully exploring all the things around.

Suddenly, a strange light flashed in Zhang Ruochen's eyes and said, "There are strange power fluctuations in the ground three thousand feet underground."

"It turns out that the Sun and Moon Dragon Spring is hiding underground this time, no wonder it can't be found." Dragon Evil Emperor said suddenly.

The earth structure of Zhenlong Island is tight and difficult to penetrate mental power. It is extremely difficult to know the situation underground.

If it were not for the secret scriptures of time and space, even if Zhang Ruochen had extremely high spatial attainments now, it would be impossible for him to reach three thousand feet underground.

After receiving Zhang Ruochen's instructions, the Dragon Evil Emperor immediately took action and used various means to dig out the passage to the underground.

However, this passage is obviously not that easy to dig. The further down, the harder it becomes. Even with the means of the Dragon Evil Emperor, it is very difficult to dig.

"Click."

At one moment, the rocks under the ground were broken, showing a dark hole, hazy mist emanating from it.

This kind of mist is very special, with the breath of the extreme yang and extreme yin intertwined, which are obviously opposite each other, but they are even more integrated.

Seeing these fogs, the Dragon Evil Emperor immediately said excitedly: "The sun and moon fogs must be below the sun and moon dragon spring."

The spring water of the Sun and Moon Dragon Spring is also of great benefit to it. If you can get more top-level holy spring water, you can baptize its own divine power and holy soul, and your strength may be greatly improved.

Zhang Ruochen circulated the "Nine Heavens Ming Emperor Sutra" and absorbed the scattered mist into his body. It was emitted from the Dragon Spring of the Sun and Moon, but it seemed that it would have an extraordinary effect.

When the fog enters the body, there is no need to deliberately refine it, it is integrated into the limbs and bones by itself.

During this process, Zhang Ruochen vaguely sensed that his body and holy soul had been slightly strengthened, and at the same time, the holy energy was a little more pure.

With his current cultivation strength, it is very rare to absorb the mist emitted from the Sun and Moon Dragon Spring to make him feel the subtle effects.

"The Dragon Spring of the Sun and Moon is indeed magical. If you can get some essence of the holy spring, you will definitely greatly improve my body and holy soul." A strong look of expectation appeared in Zhang Ruochen's eyes.

The opportunity was right in front of him, and Zhang Ruochen and the Dragon Evil Emperor would not hesitate and immediately flashed in.

Of course, they seemed very careful and completely restrained their breath to avoid disturbing the Sun and Moon Dragon Spring.

The underground space is extremely huge, with extremely rich sun and moon mists, almost condensed into liquid.

After truly entering the underground space, Zhang Ruochen discovered that it was not dim, but was shining with soft holy light.

The source of the holy light is a great sun and a bright moon, which emit golden holy light and silver holy light respectively, intertwining each other and shining brightly.

That is not the real big sun and bright moon, but the strange phenomenon that appears in the Dragon Spring of the Sun and Moon.

Using the eyes of the divine seal, Zhang Ruochen's eyes penetrated the rich fog, and wanted to observe the reality of the sun and moon dragon spring first.

"Hmm? Someone in front."

Zhang Ruochen's eyes narrowed slightly.

There are other people in the place where the Sun and Moon Dragon Spring is located, which is really not a good thing.

And just glanced at the man's back, Zhang Ruochen felt a strong sense of uneasiness in his heart, and he actually felt a very strong threat.

The Dragon Evil Emperor also discovered the person ahead and said with a slight voice: "It's the Dan Emperor, this guy has a really smart nose. It seems that he can always find the place where the Sun and Moon Dragon Spring is born."

When it accidentally found the Sun and Moon Dragon Spring, it met the Dan Emperor, but it did not expect to meet again this time.

Hearing the word "Dan Emperor", Zhang Ruochen couldn't help but frown slightly. They had just met Muzu and Sword Emperor, but they had met Dan Emperor so quickly. I really don't know if they should say they are lucky or bad.

In this way, the only one he had never seen the five overlords of Zhenlong Island was the stone emperor.

According to the Dragon Evil Emperor, the Dan Emperor is a part of the remaining essence after the Emperor's grade elixir was broken. Although it is no longer an imperial elixir, it is far more powerful than the King's grade elixir.

Dragon Evil Emperor said: "The Dan Emperor has a deep obsession, which is to regain its origin and transform it into an emperor-grade holy pill. For this reason, he devoured a large number of heaven and earth treasures, including a large number of king-grade holy pills, and at the same time, he used the Sun and Moon Dragon Spring to baptize his own elixir."

The Dan Emperor is extremely special, far better at finding various holy pills than the other four overlords. Most of the high-level holy pills retained in the Dragon God Temple fell into the hands of the Dan Emperor.

Especially the king-grade holy pills, almost thirty of them have been born over the years, and the Dan Emperor has obtained at least two-thirds of them. It was an amazing wealth that was enough to make the Great Sage jealous.

Devouring so many king-grade holy pills, I think the origin of the Dan Emperor has become extremely powerful. Giving him enough time may really hope to turn into a complete imperial holy pill.

"It's really luxurious to devour a large amount of king-grade holy pills to cultivate their own elixir energy." Zhang Ruochen couldn't help but sigh.

That is the king-grade holy pill. Each one is worth even. The ordinary great saint does not have enough holy stones to buy. Even if you get one, you may not be willing to refine it easily.

Then, a ray of light flashed in Zhang Ruochen's eyes, staring at the back of the Dan Emperor without turning his eyes. What amazing effect will a holy pill close to the imperial grade have?

Especially the Dan Emperor is broken and then established. Although it has not yet become an emperor-grade holy pill again, its effects may be not far different.

As if he understood what Zhang Ruochen was thinking, the Dragon Evil Emperor hurriedly said: "Master, the Dan Emperor is different from the Dan Spirit we encountered before. Not only does he have extremely powerful power, he also masters a variety of mysterious Dan Spirit secret techniques. It is very difficult to deal with, so it is best not to make any idea of ​​it."

"What is the secret technique of Dan Ling?" Zhang Ruochen asked curiously.

Dragon Evil Emperor said: "The secret technique of alchemy is a secret technique created by the Dan Ling of the Holy Pill. It is most suitable for Dan Ling's cultivation, so that the Dan Ling can perfectly use its powerful power."

"The Dragon Clan once used secret techniques to tame the elixirs of the Emperor's Holy Pill, taught various secret techniques, and cultivated them into peerless powerful people. The secret technique of the elixir was created by these powerful elixirs. The secret technique of the elixir mastered by the Dan Emperor was derived from the broken elixirs of the Emperor."

Upon hearing this, Zhang Ruochen couldn't help but feel moved. The Dragon Clan is indeed powerful and has even done such things.

All holy pills have spirituality. The higher the grade, the stronger the spirituality. The elixir spirits nurtured by the emperor-grade holy pills are no different from those of cultivators in terms of spiritual wisdom, and they are even worse.

Moreover, the emperor-grade holy pill contains many rules of heaven and earth. After practicing, it can be said that it will be twice the result with half the effort.

"I think now is a great time to deal with the Dan Emperor." Zhang Ruochen said with glitter.

The Dragon Evil Emperor was stunned at first, and then he realized it and couldn't help but start to mourn the Dan Emperor in his heart.

After pondering slightly, Zhang Ruochen said: "Don't alert the snake for now, find a way to collect some spring water."

Although he had a way to deal with the Dan Emperor, if he scared the Sun and Moon Dragon Spring away, it would undoubtedly be more than worth the loss.

Whether it is the Dan Emperor or the Holy Spring Water, it is his target.

Unable to help, Zhang Ruochen and Long Shahuang quietly changed direction, went around the other side, and approached the spring pool carefully.

The spring pool is oval, less than one meter square. In the middle is the spring, and golden and silver spring water is constantly gushing out from it. The two are clearly separated, just like Tai Chi.

In the spring pool, there are two petite dragons swimming, one golden dragon and one silver dragon, both of which are only about a foot long.

They are the essence of the holy spring, with a rare number, and are extremely precious for the top holy kings and great sages to practice.

As for the divine spring, it is hidden in the spring and will not be easily revealed. Only the strong men of the Shenlong clan can use it in small quantities.

Although the Dan Emperor sat cross-legged by the spring pool, he did not collect the holy spring in large quantities. It was obvious that he wanted to practice with the Sun and Moon Dragon Spring for a long time.

"Take it."

Zhang Ruochen secretly sent a message and directly sacrificed the Mercury gourd.

The Dragon Evil Emperor did not hesitate and immediately used space means to try his best to absorb the holy spring from the spring pool.

The Mercury Gourd instantly appeared in the spring pool, releasing a powerful suction force, which completely absorbed all the holy spring water in the pool.

Of course, Zhang Ruochen's main goal was the divine dragon transformed by the essence of the two holy springs, so the gourd mouth was aimed directly at them.

"roar."

The spring pool vibrated, and it made a dragon roar that shook the sky.

A hazy layer of holy light appeared, covering the spring pool and preventing the holy spring from being lost.

The next moment, the strange phenomena of the sun and moon reflected above disappeared into the spring pool, and the spring pool itself disappeared without a trace.

From Zhang Ruochen's sacrifice of Mercury gourd to the Sun and Moon Dragon Spring escaping, it was only in an instant, so fast that the Dan Emperor could not react at all.

The Dan Emperor suddenly opened his eyes, his eyes locked on the Dragon Evil Emperor, and he roared: "How dare I destroy my Emperor's practice here, Dragon Evil Emperor, are you looking for death?"

The Dragon Evil Emperor opened his mouth and swallowed a large group of holy springs taken out of the spring pool without any fear, saying, "The Dragon Spring of the Sun and Moon is not yours. I can also collect them. If you want to fight, I am willing to accompany you."

With Zhang Ruochen there, his confidence undoubtedly seems to be very strong and he does not care about the threat of the Dan Emperor at all.

"Dragon Evil Emperor, don't even think about leaving here safely today." The Dan Emperor's eyes showed fierce light and a strong murderous aura emanated from his body.

As he spoke, the Dan Emperor had formed a mysterious seal technique, released a powerful elixir, condensed a ferocious demon dragon, and pounced on the Dragon Evil Emperor with his teeth and claws.

The Dan Emperor was completely angry this time, so he took action and was a powerful Dan Ling secret technique, which would give the Dragon Evil Emperor a painful lesson.

At this moment, an ancient remains of monument suddenly flew out from behind the Dragon Evil Emperor and suppressed the Dan Emperor.

The residual monument did not show any magical features, but the hideous demon dragon condensed by the Dan Emperor with his elixir energy inexplicably dissipated.

"What's this?"

The Dan Emperor's face changed drastically, and his eyes were fixed on the flying monument.

Without hesitation, the Dan Emperor changed the seal technique and condensed a divine seal with the alchemy energy to welcome the residual monument.

A strange thing happened again. As soon as the divine seal flew out, it instantly dissipated into nothingness like a demon dragon, and even the alchemy energy disappeared without a trace.

Seeing this scene, the Dan Emperor suddenly felt cold in his heart and felt that the situation was not good.
To be continued...
