"Bang—bang—bang—bang—”

These heavy sounds seemed to come from the ground, and soon, Gongsun Mo'er even felt that the ground began to shake!

"This, is this-"

A deep sense of fear appeared in Gongsun Mo'er's eyes!

Tang Long, who was fighting fiercely ahead, had already realized that the situation was not good and was very shocked.

He knew that something even more powerful was coming here!

"No wonder these three-headed demons rushed here desperately. It seems that these three-headed demons were not here to kill Mo'er and me, but were running away. What kind of terrifying existence is ahead of them?!"

Tang Long took a deep breath.

He knew that there must be a fierce battle next!

I hurriedly took a few elixirs to recover my energy, flashed, and retreated to Gongsun Mo'er: "Wait a moment, be careful, something more dangerous may come!"

Gongsun Moer said nervously: "I know what that is. It is an underground demon that has evolved to a higher level. It should be a three-headed and six-armed underground demon!"

"A three-headed and six-armed underground demon? How powerful is such an underground demon?!" Tang Long didn't know about such an underground demon.

Gongsun Moer explained: "The underground demon with three heads and six arms is also called the underground demon king. The underground demon king has very strong combat power and can also use various magical techniques. Our current strength is probably difficult to deal with the underground demon king!"

"No matter whether it is easy to deal with or not, we must deal with this underground demon king!" Tang Long said in a deep voice.

They have no way out in this Black Stone Mountain. Even if they escape, they will eventually be caught up by the underground demon king. Since that is the case, they can only fight to the death!

"Bang—bang—bang—bang—”

The footsteps were getting closer and closer. In the distance ahead, Tang Long had already seen a terrifying monster like a mountain walking towards this side step by step!

This monster is more than 200 meters tall, and its body is extremely large, with a width of more than fifty meters!

The monster was moving forward like a thick wall.

This underground demon king with three heads and six arms!

At this time, the blood demon power was bursting wildly on the underground demon king, and the blood demon power had swept towards Tang Long and the others in an extremely fierce manner.

Tang Long's divine beasts and the 144 blood wolf had already knocked the three underground demons to the ground.

The blood wolf, the divine beast, the king of the abyss and Su Xiaoman all retreated to Tang Long.

Tang Long's face was solemn, feeling the extremely powerful aura sweeping in front of him. He knew that the underground demon king's combat power was indeed very strong, and even if it was him, it would be difficult to defeat him!

"We must use all our strength!"

Tang Long gritted his teeth, and he directly condensed the Huangquan Divine Needle!

At this time, he must stimulate his potential!

His strength has been improved, and the combat power of the King of the Abyss and Su Xiaoman can also be improved.

Moreover, the combat power of those blood wolf can also be improved together!

However, Tang Long can only stimulate his potential for ten minutes. After ten minutes, his vitality will be exhausted, and then he will be very dangerous!

But in order to defeat the underground demon king, he had to do this at this time!

After all, this underground demon king is really too powerful!

Taking a deep breath and staring at the underground demon king who was walking towards him in front of him, Tang Long's mind moved and summoned the God of Destroying Thunder!

The Thunder God of Destroying World has grown to the highest level!

Tang Long directly merged with the World-Destroying Thunder God, and his combat power exploded even more violently!

"kill!"

With a roar, his body was as anxious as lightning, and with the sound of thunder explosion, he rushed towards the underground demon king ahead!

"roar!"

Behind him, roars sounded one after another!

His eight divine beasts and one hundred and forty blood wolfs all rushed towards the underground demon king together, and the King of Abyss and Su Xiaoman also rushed towards the underground demon king together!

In a blink of an eye, Tang Long was less than 100 meters away from the underground demon king!

His eyes were bright and his fists were tightly clamped!

"Huangji Booming Sky Fist!"

A low voice sounded, and Tang Long's fist suddenly bombarded forward!

In front of the fist, a space was twisted strangely, and then, a hundred meters away, half a meter ahead of the underground demon king, a space was twisted strangely at the same time!

Then, in the twisted space, a red fire energy ball with a diameter of more than five meters, containing the powerful blood demon power and the energy of thunder and lightning, flew out directly and bombarded the underground demon king's chest!

The underground demon king wanted to resist, but he had no time at all!

Seeing that the ice and fire energy light ball had already hit the underground demon king's chest!

"boom!"

The roar of the sky sounded, as if that space was about to be bombarded and completely collapsed!

The fierce energy swept through the blood-red blood demon power, turned into a whizzing energy hurricane, sweeping in all directions!

The explosion of the ice and fire energy light ball brought out an extremely powerful energy, and with the extremely violent golden lightning, it directly bombarded the underground demon king's chest!

However, such a powerful attack only made the underground demon king take four or five steps back!

This underground demon king was completely harmed!

Seeing this situation, Tang Long couldn't help but feel a sense of shock in his pupils!

This underground demon king is so powerful!

Gongsun Mo'er was also extremely shocked. She didn't expect that Tang Long's combat power was much stronger than before. However, even so, he could not hurt the underground demon king!

The attack from the underground demon king is really terrible!

"Can he be stronger?!"

Gongsun Mo'er thought to himself secretly that at this time, she could only place her hope completely on Tang Long, because her own strength could not defeat the underground demon king at all!

Tang Long's divine beasts have also rushed towards the underground demon king together!

The King of the Abyss and Su Xiaoman also rushed over together, including Tang Long's 140 blood wolf, rushed towards the underground demon king, and all surrounded the underground demon king together!

Then, various magical techniques and magic weapons kept attacking the underground demon king!

In the midst of a fierce attack, two minutes passed in a blink of an eye!

In the past two minutes, although Tang Long and his divine beast attacked extremely crazy, such a powerful attack could not cause any damage to the underground demon king!

Moreover, the six arms of the underground demon king were still bombarding in all directions.

Every time the underground demon king bombards, a ball of extremely powerful blood-red energy light will fly out, bombarding the surrounding divine beasts such as Tang Long and the surroundings, and bombarding the bloody wolf!

Tang Long and the others are actually at a disadvantage!

If it weren't for the large combat power of Tang Long, if it weren't for the control of the pressure of Tang Long's heaven and earth, plus the control of the high-altitude Tianshen Ding, Tang Long and the others would have been very dangerous at this time!

However, at this moment, Tang Long's potential was stimulated!
