Before you know it, it's getting dark, and the night is coming!

In the depths of the "Twilight Leaf Ancient Forest", in that secluded cave, Feng Buqian was nervously rubbing his hands together, looking at the briquettes in the cave that were still motionless with his eyes closed.

I stayed up from morning to night, and Feng Buqian waited so anxiously, feeling that time was going extremely slowly, as if every second was torment!

The magic tripod hanging in the air was no longer spinning as fast as it was at the beginning, but it was emitting bursts of black light, flickering and dimming, slowly rotating, but it was still absorbing the "evil power" on the briquette's body all the time!

And the five weird magic shadows that appeared on Na Ding's body were also becoming clearer and clearer, as if they were about to break away from Ding's body at any time!

Seeing that the sky was dark, there was no sign of refining the "Five Spirits Returning Yuan Dan" in this Demon Ding, watching the "evil power" on the briquette's body being continuously eaten away by the Demon Ding, and the breath became extremely weak, how could Feng Buo's heart not be in a hurry!

But there is no way to be in a hurry, although he has the idea of rushing forward to interrupt the briquettes countless times in his heart, but he also understands that if this critical moment is interrupted, I am afraid it will only be more dangerous!

Just when Feng Buqian was anxious, he suddenly heard a muffled sound of "hum" from the Demon Ding, which was so clear in this quiet cave!

Feng Buyao was suddenly startled, and hurriedly looked up!

I saw that the magic tripod finally stopped rotating at this moment, and was quietly suspended in the air, and the black light around it also dissipated, and there was no sound at all!

But the evil qi on the briquette's body is still being pulled and devoured by it all the time!

Feng Buqian couldn't help frowning, and he didn't know what the situation was, and was about to ask Mei'er in his heart, only to hear that the magic tripod suddenly made a loud "click" sound, which was rapid and violent, and Feng Buqian was so frightened that he suddenly shuddered!

When I looked up at the magic tripod again, I saw that it was shaking wildly, as if something was about to burst out of the furnace!

At the same time, a dazzling five-colored strange light is constantly gushing out from the mouth of the Ding furnace, like a dragon, circling and flying around the Ding furnace, emitting a strange buzz!

What followed was a stream of rich Five Elements Aura, which suddenly filled the entire cave!

Feng Buyu was happy in his heart, and secretly said that this "Five Spirits Returning to Yuan Dan" had already been refined!?

At this time, I heard Mei'er scream in a little panic!

"Not good!"

Feng Buqian couldn't help but be surprised, and hurriedly asked, "What's wrong!?"

"It's going to be bad!" Mei'er's previous indifferent tone was completely gone at the moment, "Really...... What a miscalculation!"

When she heard Mei'er say "it's bad", Feng Buyu couldn't help but "chuckle" in her heart!

He hurriedly yelled at Mei'er in his heart: "Sister, what's wrong!?What's wrong!?Say it quickly!"

Mei'er also hurriedly said: "Go out and have a look!"

Feng Buqian was slightly stunned, and he didn't dare to think about it, so he hurriedly rushed out of the cave!

It was already dark outside, and the woods on all sides were very quiet, and there seemed to be nothing out of the ordinary!

Feng Buqian looked around, his heart was full of puzzlement, only to hear Mei'er say urgently: "Look at it!"

Feng Buqian hurriedly looked up, and was immediately shocked!

I saw where I was, no, to be precise, the location of the cave, and a very strange dark cloud suddenly gathered in the night sky directly above!

If you look elsewhere, the night sky is clear, the stars and moon are all over the sky, and there is not a trace of clouds, but only this strange dark cloud is pressed on the sky where it is located, and it does not move at all!

This dark cloud is not big, but it is so black and terrifying, even above the dark night sky, it is so clear and conspicuous! And this cloud is extremely low, as if it is within reach, and the purple lightning rays, like a group of snakes dancing, are constantly shuttling and dancing in the clouds, as if they are gathering momentum, and they are about to rain down at any time!

Looking at this strange cloud, Feng Buqian was suddenly dumbfounded, and his face was instantly covered with beads of sweat!

"This ...... This is 'Dan Lei'!?"

"Dan Lei", also known as "Dan Tribulation"!

As the saying goes, "things that go against the heavens will be punished by heaven," and the art of alchemy is to seize heaven and earth and create nature, which is against the way of heaven! The function of some of these pills is against the sky, and when the pill is completed, most of them will trigger heavenly punishment, and send down different degrees of "Dan Thunder" to attack the unbaked pills in order to prevent them from taking shape! Therefore, this "Dan Thunder" is also called "Dan Tribulation"!

Looking at the amazing thunderclouds in the air, no matter how stupid it is, you can guess that this is the legendary "Dan Lei"!

He stared incredulously at the increasingly alarming thunderclouds and whispered, "What...... How so!?"

He also understood that the elixir can be divided into six grades: low-grade, intermediate-grade, high-grade, and superb, holy, and divine products! According to common sense, only when the elixir refined reaches the level of a superb product can it be regarded as having the power to defy the heavens, and can it attract the "Dan Tribulation"!

But according to the calculations of Mei'er and Briquette, with the alchemy of the half-hung son of the gas, at most it is a high-grade pill, how can it lead to a "Dan Tribulation"!?

Mei'er also replied with a little bitterness: "This ...... Or miscalculated...... I don't know if the effect of the magic tripod is against the sky, or the 'fusion of yuan and evil' enhances the medicinal properties...... This 'Five Spirits Returning Yuan Pill' has obviously reached the level of a 'superb' elixir......"

Originally, this should be a good thing, but Feng Buyu not only couldn't laugh, but even had the heart to cry!

If he had known that this elixir would actually attract "Dan Lei" and make such a big noise, he would definitely have to make all preparations earlier!

You must know that this "Dan Lei" can be regarded as a kind of heavenly punishment! How can the power of it be underestimated!

Generally, an alchemist who can refine a "superb" elixir must be at least the realm of a master, and if he can practice alchemy to such a realm, his own cultivation must be extremely good! Even if his cultivation is insufficient, as soon as he speaks as an alchemy master, there are countless strong people rushing to escort them, so they naturally have the confidence to fight against "Dan Lei"!

But Feng doesn't owe it, but he is dumbfounded!

Not to mention that the briquette is now extremely weak, half-dead and has no ability to resist, even if he is his own cultivation, even if he has all the hole cards, he dare not say that he will be able to stop this terrifying "Dan Lei"!

Taking 10,000 steps back, it means that he tried his best to stop this "Dan Lei" by luck, but the huge momentum caused by this "Dan Lei" must be extremely shocking! Their current position is already extremely close to the "Twilight Leaf City", I am afraid that it will not be long before the strong people will notice the strangeness here, if the "Dan Lei" is a success, it will inevitably attract more people!

After all, an elixir that can trigger "Dan Lei" is definitely not trivial!

Even if the "Dan Lei" resisted and the pill was refined, but the hole cards were used up and the half-dead briquettes were not owed, and in the face of many strong people who were eyeing them, could they keep the pills and retreat!?

The answer, of course, is no!
