After seeing Lin Jin enter the cave, Elder Yanyu looked at the gradually closed stone wall and sighed deeply, his eyes full of solemnity.

"I don't know if this human monk has the ability to subdue that thing in the depths, maybe the hope of our clan is pinned on him...... Alas, leave it to fate. ”

And Lin Jin, who had already entered the stone cave, felt the melting heat energy since the stone wall was opened just now, especially after entering the stone cave, the heat energy was even more wanton and swept wildly, impacting Lin Jin from all directions!

Lin Jin paused slightly, put his hand on the wall of the stone cave that seemed to have an ordinary temperature, and when he landed, an unbearable heat energy squeezed into the palm of his hand, and even a treasure like Lin Jin was burned to the palm of his hand.

"It's really interesting, it seems that the universe in this cave is controlled by the fire in the depths......"

Lin Jin looked at his fiery palms as he continued to march deeper into the cave.

As Lin Jin gradually deepened, the temperature in the cave became closer and closer to the temperature that burned people's hearts when they first touched the stone wall!

And the light inside the cave is getting brighter and brighter, and the slight smooth stones embedded in the stone walls reflect a bright light.

"It's almost ......"

As the cave became brighter and brighter, Lin Jin finally walked out of the cave, and a wider environment was displayed in front of Lin Jin's eyes.

This place is a small cave in the mountain surrounded by stone walls, and in the middle is a pool of lava, and the gurgling magma bubbles burst from time to time, and the splashed magma goes straight to the dome.

The entire cavern was as bright as day, due to the blazing glow above the magma pool. It is slightly rounded, suspended on a pool of magma, and the space is slightly distorted around it!

"It seems that although it is called the Book of Fire. But it's not really the shape of a book, it looks like it...... It can be a little tricky. ”

Although Lin Jin was not completely sure, he thought that the purpose of coming to Yanmai was for what was in front of him, and now that he saw it with his own eyes, if he left, it would be very worthless.

So Lin Jin was ready to take a risk, after all, he still had three big guys living on him. If something happens to him, the three big guys will definitely not sit idly by!

With such confidence, Lin Jin did not plan to continue to grind. Let's go up and try the situation first!

Immediately, I saw Lin Jin take a step and jump to the top of the magma pool, and Lin Jin, who had already been prepared, directly put on a handprint!

"Woohoo......"

The palm of his hand rested on the piercing light, making a staccato sound.

At first, there was no sensation in the palm of the hand. But after a few moments. Lin Jin's heart moved, and a warm heat energy began to pass into his hands.

I was both puzzled and surprised, I thought that it might be a powerful and powerful energy that directly hit my arm, but in fact, it was the opposite, it turned out to be an unusually soft energy, which seemed to be communicating with me!

Frowning slightly, Lin Jin didn't feel relaxed, on the contrary. Lin Jin felt a faint sense of crisis, and there was no reason. Just a flash in my mind.

Although the time is short, this is enough to make Lin Jin more vigilant, although there seems to be no sign of resistance on the surface, but Lin Jin is ready for a large rebound that may occur later!

After all, he was in an already hot environment, so the slow heat flow from the palm of his hand made Lin Jin not feel warm at all, and even more, his face was illuminated by the blazing light, like a bloody corpse with a bloodshot face.

The heat rising from his whole body made Lin Jin's expression more and more solemn, but after all, there had not been any strict situation, so Lin Jin still quietly exchanged spiritual power with the huge light cluster.

However, after half an hour, Lin Jin's face finally changed greatly, and his solemn expression was replaced by a look of shock, because at this time, his arm on the light cluster actually began to heat up!

Not only the changes in the arms, but also the spiritual power transmitted into the body in the palms of the hands gradually increased to a certain extent.

Pulling up his sleeves, Lin Jin saw that the arm inside had been completely "burned" red and transparent by the spiritual power conveyed by the scorching light cluster, and even the acupuncture bones in the entire arm could be seen clearly!

Lin Jin could feel the majestic power implied by the external energy in his body, but it just didn't explode, so Lin Jin had been trying to refine it in order to achieve the purpose of officially connecting with this huge light group.

"Are you coming?" Lin Jin muttered as he looked at his red, bleeding and transparent arm.

Sure enough, Lin Jin hadn't said this for long, and the output spiritual power of the huge light cluster, which had always been gradually increasing, suddenly burst out from Lin Jin's palm, and the powerful fire attribute energy was directly scattered in all directions!

Knowing that the huge light cluster began to have real movements towards him, Lin Jin smiled faintly, after all, he had already prepared, and slightly endured the feeling of pain in the acupoints caused by the spiritual power transmitted from his arm, Lin Jin began to try his best to guide those manic and violent fire attribute energy into his body.

As Lin Jin expected, when the huge fire attribute energy rushed into the body with the destructive power of destruction, the two big men in the body and the purple mansion finally made a move.

"I said, boy, you are very capable! This fire attribute energy is not ordinary, I won't be able to withstand it when the time comes...... You'll just see what happens......"

The blood dragon had already wanted to stop Lin Jin from making moves on this huge ball of light from the beginning of the Purple Mansion, but thinking that Lin Jin's strength was for him to plan for the future, he still held back.

Now that something is really wrong, the blood dragon has a helpless look on his face, and there is still a lot of solemnity in his helpless expression, this fire attribute energy seems to give him a lot of pressure, which makes Lin Jin also slightly surprised.

But this is not the time to be surprised and inactive, Lin Jin controls the energy emitted by his divine sense and the blood dragon lotus to control the acupuncture points and meridians all over his body, forcibly stabilizing the situation, if there is a small mistake in the rupture of the acupoints at this time, the danger may expand infinitely!

And what the mysterious plant did was not simple, releasing a steady stream of turquoise spiritual power to fuse into that fire attribute energy, and began to assimilate that energy like a wild horse that had taken off the leash.

The hand-in-hand division of labor between the two bigwigs directly made the chaotic situation in Lin Jin's body much more stable.

And it was also at this opportunity that Lin Jin deliberately dispersed a part of his divine consciousness into the huge light cluster, which made the blood dragon unbearable.

"When the situation of the acupuncture veins in your body is a little stable, you will take out a part of your divine sense, and you will not be able to control the situation later, then you can only resign yourself to fate!"

Lin Jin said: "If you want to really control the situation, you must first fully understand the situation, if I don't find out what kind of mystery is hidden in this light group, do you think you can control the situation?"

Immediately, he didn't pay attention to the blood dragon, and directly infiltrated a part of his divine consciousness into that huge light cluster, to Lin Jin's little surprise, his divine sense easily penetrated into the huge light cluster, and the scene inside surprised Lin Jin!

The scene in the light cluster was like a copy of another flame vein, or even more than that, the endless bare mountains, and the steaming heat made it possible to only faintly see the scene in the distance, hazy, like a fog.

There is no place in the whole space that is cool, there is no hottest, only hotter, although Lin Jin is only a divine consciousness into the huge light cluster, but he still really understands the hot environment!

Lin Jin felt the huge heat energy that was continuously being transmitted to his body, and as he moved forward with the source, it didn't take long for him to come to the foot of a towering mountain peak in this space.

"I was covered by the white heat just now, and I really didn't see this peak......

Lin Jin could feel that the continuous output of spiritual power came from this peak, although he couldn't feel that there was anything special on the peak, but Lin Jin knew that on this peak, there was something he was looking for.

It didn't take long for Lin Jin to come to the top of the peak, and a small flat land appeared at the top of the peak, and when Lin Jin stepped on this small flat land, he saw a hanging object at the edge of the top of the mountain from a distance......!
