After a long time, the old man stared at Chen Yuan, and finally said: "As long as you can succeed in the first stage, I promise you that I owe you a favor." ”

Chen Yuan nodded.

Subsequently.

He utters a series of things that are completely incomprehensible.

As soon as Chen Yuan's voice fell, the old man directly stretched out his big hand and directly took out a green insect with a thick arm from a coffin, this insect was covered with green-gold light, and its head was extremely peculiar, like a tiger and a leopard, and it had two rows of dense sharp teeth, especially its dark green eyes, which were even more weird.

When it came out of the coffin, its body rolled up directly, its eyes flashed, and its original dark green eyes directly turned into blood, and two bloody lights cut through the sky like divine blades.

Sheng Xueqin and Chen Qi only came into contact with this blood light with their eyes, and their bodies were immediately cold.

This shocked the hearts of the two of them, this 'bug' is absolutely extraordinary, this is definitely at the level of the demon king, in other words, it is quite a saint monk of the human race!

The old man directly grabbed the worm, easily knocked it out with one hand, and then directly dazzling it and took blood.

Its eyes and six drops of black blood dripped into the dark flames of the underworld.

The underworld had turned into countless ancient symbols, all of which fused under the black flames, turning into a black mass of unidentified objects.

When the eyes and six drops of blood dripped into the black underworld, the black flames suddenly surged, and the entire underworld was like a frying pan, sizzling, and a cloud of blood mist appeared.

However, in an instant, before the blood mist could disperse, it was directly absorbed by the underworld.

The underworld was like a living object, and it directly opened its mouth to devour all the blood mist.

"Tongue, tongue, horn, blood, fast!"

One picture after another flashed in Chen Yuan's mind, and after seeing the blood mist being directly devoured, he immediately shouted loudly.

The old man shot as fast as lightning, and instantly opened a sarcophagus again, and directly grabbed a black dark Jiao from it, as soon as this dragon appeared, Sheng Xueqin and Chen Qi were immediately moved.

The Jiaolong of this breath has existed for at least hundreds of thousands of years, and the cultivation of the Jiaolong clan is extremely difficult, and the cultivation of the Jiaolong clan is only stronger than that of the demon king, although they don't understand why the breath of this Jiaolong is so peculiar, it is completely different from the Jiaolong clan they have seen, but this does not prevent the two of them from feeling the horror of this Jiaolong.

However, as soon as Jiaolong, who was not weaker than the demon king saint, appeared, he was directly grabbed by the old man, and his palm was pinched at will, and he was directly pinched to death!

Then, according to Chen Yuan's instructions, the tongue, horns, and blood were taken, and then the three were fused and directly introduced into the underworld.

"Moo!"

When these three things were integrated into the underworld, the entire secret recipe suddenly became irritable, like an angry dragon running wildly in it, constantly galloping, and even rushing up.

The whole underworld began to shake, as if a real dragon was about to rush out of it.

But.

No matter how violent it was, no matter how much of the shock it caused, it could never break free from the underworld.

At this time.

Sheng Xueqin and Chen Qi realized that this underworld formula is definitely a supreme treasure.

The underworld made up of countless ancient symbols formed a black object, which became thicker and thicker, and more and more violent, and finally seemed to go crazy to the extreme.

"Hidden Black Water, it's now!"

Seeing this, Chen Yuan immediately shouted.

The old man did not take anything out of the coffin this time, but carefully took out a black bottle from his bosom, poured half of the black liquid into it, turned it into thousands of droplets, and sprinkled it directly on the black object that the underworld had turned into.

When all this was done, the atmosphere in the whole small world suddenly became solemn.

Chen Yuan stared intently at the changes in the underworld, and he couldn't escape his eyes at all.

As soon as the timing came, he immediately asked the old man to put down what he said, the old man shot as fast as lightning, as long as Chen Yuan said it, he did not hesitate to do it directly, and the weight of the delivery was not bad at all.

Chen Yuan quietly observed the changes in the underworld, grasped the opportunity, and said one after another strange creatures, medicinal materials, and so on.

With the change of the underworld, Chen Yuan's application became more and more solemn, and even his breathing became a little short.

Before he knew it, sweat the size of a soybean was left on his forehead.

In fact.

At this time, it was not only Chen Yuan who was nervous, but even an unfathomable figure like the old man was nervous, and his eyes were also staring at the changes in the underworld.

And Sheng Xueqin and Chen Qi couldn't help but get nervous, after all, they had never seen this kind of formation.

Of course, both of them knew that the changes in the underworld were absolutely extraordinary, and as for what kind of changes would occur in the end, they didn't know.

All kinds of medicinal materials, spiritual materials, and life materials are put into the underworld, and the underworld is ever-changing, sometimes turning into a dragon, sometimes turning into a phoenix, sometimes turning into ice, sometimes turning into water, sometimes condensing fire......

As more and more things were put in, the underworld became more and more violent, as if it were a living thing.

With the passage of time, the underworld, which was originally only violent in a radius of ten zhang, seemed to break through this confinement at this time, crazy and crazy, frantically hitting the surrounding space, and even knocking out one spatial hole after another, trying to escape from the space.

Two more hours passed.

It is almost coming to an end, and at this time, not only Chen Yuan, but also the old man has become more concise than before.

The old man, who originally looked stiff and moved like a dead man, actually had a drop of sweat on his forehead, which was enough to prove how nervous he was.

"Lock the water!"

Ultimately.

Chen Yuan said the last piece of material.

At this moment, his heart suddenly hung high.

"Boom!"

When the water locked into the underworld, the entire black underworld cube transformed by ancient symbols was like a frying pan, and a peerless momentum erupted wildly.

At this moment, the entire small world seemed to be trembling and crumbling, as if this world could not withstand this breath and would be destroyed at any time.

"Boom, boom!"

The underworld was furious, but as time passed, the peerless aura became weaker and weaker.

to the end.

The underworld, which was originally encapsulated by a black object, began to turn amber.

At this time.

There was only a slight sound of breathing left in the entire small world, whether it was Chen Yuan or the old man, or even Sheng Xueqin and Chen Qi, they were all holding their breath and staring at the underworld.

Especially Chen Yuan and the old man, they were staring at the underworld.

They know it's the last minute!
