Chapter 645

After half an hour, Ling Yunfan and Zhan Tian stopped in front of the cave they had been looking for for for a long time.

Looking at the endless deep underground cave that constantly emits very strong fire attribute energy in front of us, Ling Yunfan asked with a slight frown: "elder, are you sure that the last cry for help from elder Shanxi came from here?"

Although we know that the other party will not be idle and cheat ourselves, the size in front of us can only accommodate a single person at one time. Not only does it not emit any vitality that belongs to creatures, but also there is no unique demon yuan fluctuation of demon family members, which is really difficult to make people believe that there will be two demon king levels below.

"I'm sure it's right here." seeing his question, Zhan Tian gave a firm answer without thinking, and then added: "This is the underground cave we found when we came here to explore. At that time, there was no spirit devouring gas in this secret place. It was because we broke the stone wall seal on the underground cave that those annoying smells were everywhere."

After saying that, he didn't forget to show a look of fear on his face. It can be seen that he should have experienced the feeling of being invaded by the spirit eating Qi at that time, so his body still shivers at the thought of that feeling.

"Now that this is the case, let's hurry down and have a look. I hope senior Shanxi will never have an accident." seeing that the other party is so sure, Ling Yunfan doesn't continue to delay time, but nods to respond. He is the first to gather a layer of spiritual barrier around his body and seriously jumps into the bottomless underground cave.

"Wait for me."

Seeing that he didn't say much, Zhan Tian jumped in and immediately followed him with a cry.

The underground cave was as deep as a bottomless cave. After jumping in, a few minutes passed without any sign of landing, but before long, Ling Yunfan found something wrong.

That is, the underground cave that was still getting hotter and contains rich fire attribute energy gradually disappeared with the increase of their falling depth. Until now, not only did it disappear completely, but there were bursts of shivering ice energy continuously overflowing, resulting in a layer of crystal clear pure white ice in the dark and narrow space.

At the same time, it was covered with countless colds, which instantly reduced the climate by more than 100 times, which made Ling Yunfan, who was not too strong in physical quality, tremble slightly. If he hadn't released a little purple cloud fire to protect his body, he would have been frozen into ice, and Zhan Tian above was a little better than him.

After all, as a member of the demon family, the physical quality is much higher than other creatures. Although it is still a little affected, it doesn't matter.

"Da Da..."

Soon after another cup of tea, Ling Yunfan and Zhan Tian finally passed through the cold environment and fell at the end of the underground cave.

When they fell to the ground, they looked at the incomparably vast space curiously, as if they were unwilling to believe that such a large underground world could be hidden at the end of such a small underground hole.

The stone wall here is very simple and has nothing special. Except that it is covered with a layer of light blue ice with strong ice energy, it can be said that it is an ordinary cave built entirely by human hands.

"I always think there is something wrong with this cave." standing here, Ling Yunfan looked at the research bracelet that occasionally emits a little weak red light on his right hand. He always felt strange in his heart, but he couldn't find anything when he thought about it carefully.

"It's right ahead. Let's go."

While he was deep in thought, Zhan Tian next to him quickly patted him on the shoulder and said, and took the lead in driving along the direction of Shanxi and tongcha's breath in the distance.

Seeing this, Ling Yunfan naturally quickly followed.

Just as the two of them hurried along the direction of the breath, there was a secret room filled with eight strange black Rune pillars in all directions of the underground space.

There are two middle-aged men with ragged and ashen faces. Their breath is very weak. They are bound by the black chain condensed by eight strange stone pillars, and they are also trapped by the barrier that seems to be full of energy of ice and fire.

If someone saw them at this time, they would never believe that the breath was weak and the vitality of the whole body was extremely weak. It seemed that the middle-aged man who had half stepped into the coffin was actually the two famous demon kings in the demon domain, Shanxi and tongcha.

"Damn it, I didn't expect that these damn chains have the ability to absorb our demon yuan and the source of life. I'm afraid it won't last for a few days......" seeing that the breath on his body is getting weaker and weaker and the demon yuan can no longer be used, Shanxi said very weakly.

When his words fell, the pupil who was lying on his side was also desperate and said, "Hey, this array can't be cracked by our existence at all. In addition, Zhan Tian and the little brother Yunfan may not be able to break the array and save us even if they come here. This time they are really planted here."

After that, he was already very weak, so he slowly closed his eyes and saved his little strength to see if he could hold on for a while.

"That's right. I didn't expect that there was a terrible array in the world that could make you and me unable to resist. Even if the boy and Zhan Tian came, it was useless." hearing his words, Shanxi gradually gave up hope and closed his eyes in despair.

When they originally found the cave, they planned to go back and call Ling Yunfan and Zhan Tian directly. However, at that time, one accidentally was forcibly brought in by the suction suddenly released from the cave, then let it go and explore it. Finally, under the guidance of fate, they came to this dangerous place.

Then there is the current bad luck.

At the same time, on the other side, Ling Yunfan and Zhan Tianliang also rushed to this side since they realized that there might be something wrong with their companions.

However, it didn't take long to be stopped by the suddenly closed stone wall.

"Little brother Yunfan, do you think there's something sealed on the stone wall?" Ling Yunfan planned to attack with all his strength to break the stone wall that exudes a defense that is no worse than the defense secret treasure of the intermediate holy ware level. Zhan Tian nearby suddenly found something and said with a slightly wrinkled eyebrow.

Hearing his words, Ling Yunfan immediately stopped gathering thunder and fire, cut off his fist, and immediately looked in the direction pointed by the other party.
