Deep in the belly of the mountain, Fang Yan looked at the huge cave space underground, the fiery red magma was boiling and rolling, and a stone extended from the rock wall to expose the magma, and if you looked closely, this stone did not look like a stone at all, but like a living thing.

Fang Yan flew down, Senior Sister Hu and the others wanted to stop it, but they didn't have time.

Standing on the stone, feeling the scorching heat around him, Fang Yan carefully looked at the stone under his feet, although the texture was the same as the stone, he could vaguely see that this was the substance of the animal's body, not a stone.

Looking at the magma at the tail, Fang Yan didn't blink his eyes, and after a while, he vaguely saw a little flame floating and sinking in the magma.

After asking in his heart, Zhi Brain gave the answer at the same time: "Earth Dragon, Yarm, God-level demon beast, is sleeping at the moment, as long as it does not affect the Earth Dragon Tail Fire, it will not wake up." ”

"Yes, sure enough, it is the tail fire of the earth dragon, I can't imagine that there is no intention to plant flowers and flowers, and I have no intention of planting willows and willows, and the earth dragon is sleeping under the black water and white mountain, by the way, I misunderstood the meaning, under the black water and white mountain, it is under the mountain, not under the grassland. ”

Fang Yan smiled and waved his hand, and the gossip furnace flew out, rising in the wind, and in an instant, it turned into a three-zhang height and fell into the magma at the tail end.

"Fang Yan, stop. Senior Sister Hu jumped down, fell to Fang Yan's side, and stopped. "You're crazy, aren't you afraid of waking up the Earth Dragon?"

Fang Yan looked at her indifferently and said, "You will wake up the Earth Dragon even more if you do this, I have my own measure, if you are worried, you can leave with them first, I am enough here." ”

Lin Feng and the others also fell down one after another, persuading: "Fang Yan, don't be impulsive. ”

"What do you think of me, thinking I'm going to die indiscriminately?" Fang Yan looked at the four of them, a smile on the corner of his mouth. "You go up first, and then I'll talk about it when I've refined the dragon scale armor. ”

Seeing that everyone didn't react, Fang Yan said again: "By the way, give me the dragon pattern sword and dragon slaying knife, and I will also improve it for you by the way, Feng Bao, watch the sandworm mining machine carefully, don't be in a situation." ”

"You won't alarm it, will you?" Lin Feng looked at the tail of the earth dragon under his feet, and was also a little shocked, this thing was too big, just looking at the tail was bigger than a sandworm, it was hard to imagine what the situation would be after it woke up, so everyone was afraid.

Fang Yan drove away angrily: "There's a lot of nonsense, I still have to find a way to save my sister, do you think I will sacrifice my life to defend the south?"

Senior Sister Hu breathed a sigh of relief and said, "Be careful yourself, don't get out of trouble." ”

"Hurry up, hurry up. Fang Yan drove people impatiently, and after everyone went up, he began to refine the weapon.

Three dragon-patterned swords and dragon slaying knives were thrown into the Bagua Furnace along with various materials and dragon scale armor.

The natural underground cavern, the environment is large enough, and there is a magma lake, and the endless fire of the lungs emerges from the magma, which can be described as a natural treasure.

The spirit stone in Fang Yan's hand flew out, hit the rock wall, and quickly combined into a set of magic circles, after urging, the temperature of the cave space suddenly dropped a lot, the raging flames wrapped the gossip furnace, and the magma lake seemed to be not as active as before.

Sitting cross-legged on the tail of the earth dragon, Fang Yan guarded the gossip furnace and began to refine the weapon.

With the help of earth and fire, the smelting of materials is faster, and the huge aura contained in the fire of the earth lungs is more abundant than a small spiritual vein, after all, this is the place where the earth dragon sleeps, and the aura will naturally not be worse than the large spiritual vein, otherwise the earth dragon will not choose to sleep here.

Hidden inside the mountainside, everyone didn't need to care whether there would be barbarians searching for them, but more worried about whether the earth dragon would be awakened, or whether the sandworm mining machine had accidentally dug a tunnel.

For this reason, Senior Sister Hu and Lin Feng stayed outside the cave, and Feng Yu and Fang Fengbao took turns guarding the sandworm miner, for fear that the tunnel collapse would alarm the earth dragon, or the sand worm mining machine would dig the earth dragon.

There was an explosion in the "boom" cave, and Senior Sister Hu and Lin Feng's tense nerves were touched, and the two of them looked at the cave together, and saw that everything was as usual, so they breathed a sigh of relief and turned to look into the depths of the tunnel.

"Listening to the sound, it seems to be coming from outside, Feng Bao and their side are not moving, it should be the barbarians who searched for it and attracted the mechanism left by Fang Yan. Lin Feng went to the fork of the tunnel to check it and came back.

Senior Sister Hu breathed a sigh of relief and said: "We are now inside the mountainside, the tunnel is like a labyrinth, even if the barbarians come in, they may not be able to find us in a short time, now we are waiting for Fang Yan." ”

The two of them looked at the cave with solemn expressions, and their hearts rose to their throats, compared to being chased and killed by barbarians, the two of them would not be as urgent as they were at this moment, it felt like wandering left and right on the line of life and death, and a careless situation was a catastrophe.

In the cave, Fang Yan had completed the final steps, waiting for the process of recuperation, guarding the gossip furnace, Fang Yan looked at the plan given by Zhi Brain, and looked at the earth dragon tail fire in the magma from time to time.

When the temperature was almost raised, Fang Yan raised his head and said, "Let Feng Bao bring me the sandworm miner." ”

Senior Sister Hu frowned and said, "What else do you want to do?"

"It's a pity that such good conditions are not well used, I'm going to rerefine the sandworm miner, hurry up, don't talk nonsense. ”

Senior Sister Hu and Lin Feng glanced at each other, and the two of them had no choice but to follow him for the time being, for fear that he would be impulsive.

It's normal for everyone to be so worried, if Fang Yan didn't have a Zhi Brain, he would also be worried, with a Zhi Brain reminder, he wouldn't be worried that the Earth Dragon would be awakened at all, and he could rest assured that he would boldly use this environmental refining weapon.

The sandworm mining machine was brought back, just in time for the Bagua Furnace to open, and the quality of the dragon pattern sword and dragon slayer knife after refining was even higher, but after everyone got it, they couldn't be happy at all. Watching Fang Yan use the Bagua Furnace to put the huge sandworm mining machine in, although he was a little surprised, he was quickly overwhelmed by worry.

The space inside the Bagua Furnace is huge, and it can be regarded as a space treasure of Nasumeru mustard seeds, even ten times larger than a storage bag, and it is not a problem to fit the sandworm miner.

Various materials were put into the furnace, and Fang Yan threw all the remaining more than ninety percent of the materials collected during this time into the furnace.

The people who stood on it and watched saw Fang Yan dumping the materials in the storage bag into the Dan furnace, their eyes widened instantly, and they covered their hearts one by one, and the feeling of pain overwhelmed the worry in their hearts.

After having the sandworm mining machine, everyone also saw the speed of this thing to collect resources, which is not comparable to everyone at all, a small hill of hundreds of meters, at most half a day can be hollowed out, the black water and white mountains are rich in resources, during this time, the sandworm mining machine collects a lot of materials, that is to the mountain to remember.

Seeing these materials thrown into the furnace, no one could stabilize their minds, especially Fang Fengbao, if he didn't know that below was the place where the earth dragon was sleeping, he would have to rush down and forcibly stop Fang Yan.

"Willing, willing, giving will be gained, now waste a little material, after the sandworm mining machine is upgraded, there will be more resources waiting for me to mine, everything will be earned back, don't feel distressed, don't feel distressed......" Fang Fengbao was like entering a magic barrier, pressing his hands to his heart, walking back and forth, constantly chattering, and comforting himself.

The other people were also blushing, and finally sighed and turned their heads away, out of sight and out of mind.

Not long after, there seemed to be movement in the tunnel of the mine, and the four of them were alarmed in an instant.

"Fengbao, you stay here, and I'll go with Lin Feng. Feng Yu stretched out his hand to stop Senior Sister Hu and Fang Fengbao.

Senior Sister Hu reminded: "Be careful, don't move too much, if you can't do it, then blow up the mine." ”

Feng Yu and Lin Feng nodded, and the two of them got into the tunnel and disappeared into the darkness in an instant.

Senior Sister Hu and the others, who were staying in place, quickly noticed the aura fluctuations of the fight coming from the tunnel, and in just a moment, everything returned to calm.

Lin Feng and Feng Yu have a new dragon scale armor to protect themselves, and the bald people of the Martial King level are not afraid, and then there is the upgraded dragon pattern sword, and there are a large number of materials collected by the sandworm mining machine during this time, the spirit stone pipe is enough, and the quality is still high, and the strength of the two has risen greatly, and the four barbarians are naturally easy to solve.

The barbarian corpse was put away in the carry-on bag, and the two of them burrowed into the fork in the road, hiding in the darkness, lurking like hunters.

The sandworm miner hollowed out the belly of the mountain, making a tunnel like a maze, and it was easy for unfamiliar people to get lost, so Fang Fengbao was mainly responsible for following the sandworm miner, and knew the map of the mine, familiar with the tunnel section, and let everyone know.

Although Feng Yu and Lin Feng couldn't be as familiar with the entire mine tunnel as if they were their own like Fang Fengbao, they could also determine the direction and road section, and they wouldn't get lost in it.

The barbarians don't understand, they can only explore the road slowly, and when there are forks in the road everywhere, they can only continue to divide the troops and divide the way, which leads to the barbarians being gradually dispersed, and a team of up to five people.

After Lin Feng and the others killed another team of people, they disappeared into the fork in the road, and after a while, three teams of barbarians came with fluorescent stones, although they found traces of fighting, they could not find the corpses.

The barbarians muttered for a moment, as if someone was frightened, and the leader was dispelling their fears and letting them continue the search.

There were about twenty of these barbarians gathered, and one of them was a bald man, these people no longer divided into groups, and went all the way, but after walking for a while, they came across a crossroads, and in desperation, they could only explore separately.

After everyone separated, one of the teams gradually approached the tunnel where Lin Feng and the others were.

However, at a distance of 100 meters, another fork in the road appeared, and this group of barbarians looked at each other, and in the end they could only divide into teams again.

The four barbarians got into the tunnel, walked for about ten meters, and a corner appeared in front of them, and the four of them turned around cautiously, but they didn't see anything.

Just when the four of them breathed a sigh of relief, suddenly, on the top of the cave, the sword light fell, Lin Feng and Feng Yu rushed into the crowd, the dragon pattern sword light flew, the fluorescent stone flew down, and finally fell to the ground, and the four barbarians also fell.

After a few moments, the corpse disappeared along with the fluorescent stone, and the cave was dark again, and there were barbarians chasing and fighting, but still nothing was found.
