Feng Lai returned to the cave and went to the book room to look for books on spiritual practice. Finally, he found a bundle of bamboo slips on top of a bamboo frame in a corner.

According to this bamboo slip, the herbs left in the medicine room are extremely powerful, and generally cannot be directly eaten or used externally, either refining them into pills, or dividing them into several parts and soaking them in the spiritual pool.

Feng Lai began to throw an entire fire tongue grass into the spirit pool, and in the eyes of connoisseurs, it was purely looking for death, even if he did not explode and die, there must be a dark disease left in his body. Fortunately, the wind came to go out to fight and output all the irritable and uncontrolled fire aura in the body, so as to avoid further losses, the fire aura is a very aggressive aura, and if it is used well, it can defeat the opponent and stand out from the crowd, but if it is not used well, it will also hurt itself.

The wind came into the spiritual pool, looking at the light red water and exhaling again and again to adjust his mood. At this time, the fire aura in the pool water was no longer irritable at the beginning, and it also tended to be calm. Even if Feng Lai is in the spirit pool now, there will be no phenomenon of spiritual energy infusion.

Adjust his state, Feng Lai feels that he is an empty container, the slightest fire aura enters the body along the pores all over the body, and swims along the veins of the muscles and bones, and the fire character formula in Feng Lai's body runs independently, and the gradually accumulated fire aura flows in the body like a stream. First there were many circles of small weeks, and then several circles of big weeks, and in the smooth operation of the fire word formula, Fenglai once again felt the restriction of a bottleneck. This time Feng Lai did not choose to guide the impact of the aura, he just ran the fire word trick over and over again, until he felt the proficiency of the use of the water and suddenly found that the bottleneck had disappeared at some point, he felt like an empty container again, and he could hold more aura, the operation of the fire word trick accelerated, Feng Lai felt a burst of heat in the palm of his hand, and when he looked up, a fire mark was slowly outlined by the fire aura emerging in the body, but it seemed more and more difficult, the wind came to absorb the aura at a uniform speed, and the outline of the fire mark was still carried out at a visible speed despite the slowdown in speed。

The water in the pond was almost crystal clear, and when the wind came to absorb the last trace of fire aura, the palm fire seal happened to complete the last stroke.

At the first glance of the complete fire seal, Feng Lai felt a roar in his head, and he was immediately stunned.

......

A cavern filled with lava.

The temperature of the space is not much higher, and even the surrounding rocks have a tendency to melt, and from time to time, rocks will explode from the middle, gushing out tongues of fire that look like blood. There is almost no ground here, and there is a sea of magma everywhere, except for the occasional few rocks that can be seen outcropping, and the magma stands alone, seemingly threatening to collapse and disappear at any moment.

The sound of "jingle bells" chains colliding with each other echoed in the cave, and five huge iron chains hugged by five people stretched straight into the lava in the rock wall above the center of the magma. The rolling magma washed over and over the walls of the cave, and with each impact, the rocks peeled off, fell into the magma, floated, and then slowly melted away.

The middle of the magma slowly rose, and a huge figure slowly rose from the magma, it was a giant dragon covered in red, the scales of the dragon were densely arranged on the surface of the body, and the light of the flames glowed with a metallic luster.

Five dark chains squeezed into the dragon's body, and in the part of the chain that entered the dragon's body, bright blood could be faintly seen flowing out, submerging into the surrounding magma, stirring up waves after waves. The huge dragon's head looked tiredly at the place above the cave where the iron chain was born, and opened its mouth to let out a roaring dragon moan, and the whole cave was shaking for it, and the endless rocks disintegrated and fell, but it was impossible to reveal the end of the chain.

The dragon slammed its tail and slammed it into the chain, causing a spark and a sharp roar, but there were only a few tiny white marks on the chain, and then there was no trace after being washed by the magma.

The fire dragon swayed its huge dragon head from side to side, and although its eyes were full of majesty, it could not hide the deep exhaustion under its pupils. In the distance, a red-robed man looked at the fire dragon quietly, and made a low "gurgling" sound, like the friction between bones, which made people feel uncomfortable all the time. The fire dragon slapped the dragon's tail vigorously on the surface of the magma, and suddenly stirred up a thousand zhang waterfall, instantly destroying the reef where the red-robed man was standing.

Flames erupted from the dragon's mouth, scorching everything in the cavern, crackling, and a cloud of dragon scales quietly fell off, flying along the base of the chain in a rush of fire and magma, only to disappear into it as it approached the rock wall.

The red-robed man slowly flew up from under the magma, and the sound of "gurgling" seemed to drown out the roar of the fire dragon, becoming the only sound in the cavern, making people feel endless fear and despair. "Gurgle...... Gurgle"

Above the surface of the Spirit Pool, a figure floated on it, motionless. It was the wind that had been unconscious for three days. The eyes rolled under the closed eyes, the eyebrows that were not long were slightly raised, and then the sound of choking and coughing suddenly sounded. "Ahem...... Choked ......"

The wind came and flipped and floated on its back. A foul stench came from his body, almost causing him to vomit.

At this time, Fenglai's whole body was covered with a layer of stinky black substance, and only two eyeballs were still spinning outside. Feng Lai quickly washed off the stains on his body, he really couldn't stand the smell. After tossing in the water, the wind finally completely removed the stains, and suddenly found that his complexion was slightly pale compared to before, and his muscles and bones were also extremely active.

Clenched his fist and pushed forward, the strong fist wind pushed the water surface to splash and hit the rock wall, leaving a sub-fist print. Since that day there was a breakthrough, Fenglai's body has changed a lot, although his own realm is still in the early stage of Qi refining, but Feng Lai has an illusion, even if he faces people in the late stage of Qi refining, he will inevitably be unable to fight.

Spread out the palm of his right hand, a fire-colored mark appeared from time to time.

"Fire breath!" were the two words that came to mind when the wind came to look at the sigil. "The breath of fire, the soul of fire, a thought burns, eternal nothingness. Reciting these sixteen words silently in his mouth, Feng Lai felt that the fire mark in his palm contained some fire-based moves, and he had already explained to himself.
