The principle of firearms is actually very simple, in the time of the earth, gunpowder was used as the power, and hot weapons replaced cold weapons. In this world, if you just use gunpowder instead, even if the power is the same as in the previous life, it will not have much effect on this world.

And Fang Yan took a trick and changed the way, using the power of the spirit stone combined with the formation drive, just a sample of the experiment, the power is not worse than that of a sniper rifle.

The theory of this gun is simple, the structure is extremely easy to crack, and as for the formation inscription on it, although it is more precious, if someone gets this sample, with the heritage of this world itself, it is enough to easily develop and develop it and create unimaginable energy weapons.

The characteristic of the spiritual power gun is that ordinary people can use it, and people with weak strength can also use it to kill stronger opponents.

A world has its own architecture, and breaking this architecture will inevitably lead to unimaginable disasters, so everyone will stop Fang Yan. Because the three of them had seen the structure of the gun and understood some of the principles, they could all copy similar firearms, let alone those refiners.

Putting away the gun, Fang Yan packed up his things and said, "Let's go, the oil well should have almost been drilled." ”

Feng Yu still didn't forget about the gun, and persuaded: "Fang Yan, it's better to destroy that thing of yours, keep it, I'm still not at ease." ”

"I've said it all, you can rest assured, don't keep talking, you'd better forget about it, you should worry about it the most, it's still you. Fang Yan's words suddenly woke up the three of them.

Fang Fengbao slapped his head suddenly, and said with a frightened expression: "Brother Yan, if your gun is made a little bigger and equipped with a stronger spirit stone, I am afraid that the power will not be worse than that of the ten directions." ”

Everyone looked at Fang Fengbao with a look of surprise, they were all a little surprised, they could understand him in hindsight, but they didn't expect him to think of this and develop a more powerful weapon.

Fang Yan slapped him on the back of the head and said, "What nonsense, you'd better rot this matter in your heart, if it leaks out, the clan will be finished." ”

Fang Fengbao didn't think of this for a while, Senior Sister Hu and the three of them had already understood, nodded solemnly, and decided to rot this secret in their minds.

After a while, Fang Fengbao suddenly realized, and said in a cold sweat: "Oh, mom, Brother Yan, what kind of ghost are you making, it's even more evil than the Demon Lin Sword, that thing can even be imitated by me, if it spreads, not everyone can make it, as long as there are enough spirit stones......"

"Shut up!" Senior Sister Hu and the three of them stopped together.

Fang Yan smiled and patted Fang Fengbao on the shoulder and said, "It's okay to rot in your heart, unless you want the Fang family clan to be destroyed and everyone becomes a slave or a commoner." ”

The strongest thing in the clan is that there is a inheritance, the children of the family have its inheritance, passed on from generation to generation, the incense is not extinguished, if there are one or two talented children, the family can be revitalized, so as to ensure that the clan is not destroyed, and will always be invincible.

Strength is the foundation of this world, and the clan holds the power, so they are higher than the supreme king of the people, higher than the city lord, and the appearance of firearms, this new power is very easy to spread, so that an ordinary person can challenge the martial artist and even the martial honor, which will also shake the foundation of the clan, so everyone will be afraid.

A person from the clan, no matter how stupid he is, no matter how idiotic he is, what can be imprinted in his bones is for the sake of the clan, Senior Sister Hu and the three of them are not badly qualified, they can be regarded as superior, starting from the foundation of the clan, and seeing through the essence at a glance, this can understand the harm of guns, even if Fang Fengbao is a little second, but in the end, he can understand it.

For the clan, Fang Yan didn't have the slightest emotion, except for the relatives he cared about, he didn't think about anything else at all, and it was also after he refined the gun that he was awakened by the three of them, and then he suddenly understood that there were still such things hidden behind this thing.

Looking at the solemn and tangled looks on the faces of Senior Sister Hu and the others, Fang Yan had a smile on the corner of his mouth, and said with a secret smile: "I am reluctant to bear the power of the gun, but I am worried about the harm it brings, the charm of Pandora's Box lies in this, I don't know how you will choose in the end?"

As for the gun, Fang Yan also wanted to see what height he could develop to with the foundation of this world, and what kind of powerful gun he could make when he reached the ninth level refiner, or even the god-level refiner.

The Jiuqu River flows out of the black water and white mountains, flows through the grassland, and nourishes the land outside the Saiwai. When everyone came to the Jiuqu River, the water surface of the river was already covered with a layer of oil, and they didn't know how far it had spread downstream.

Lin Feng looked at the upstream mountains and forests and said: "The oil well is in the mountains and forests upstream, isn't it there that it has been detected, and there is no black fire oil?"

Fang Yan walked along the river towards the mountains and forests: "In fact, black fire oil is like a vein, there is a vein buried in the ground, and it can't be detected, it is beyond the distance, it doesn't mean that it can't be dug down." ”

The five of them entered the mountain, walked for several miles, and then stopped in the canyon, where the river water began to diverge from a canyon more than ten meters high, and the top was clear river water, and when they arrived here, there was a slimy oil gushing out from under the water, impregnating the river water.

"Brother Yan, where is your sandworm mining machine, why haven't you seen it?" Fang Fengbao searched around, but he didn't see the sandworm mining machine.

"We're late, it's already on its way to the Temple of Earth. Fang Yan looked casual, as if he was saying, have you had breakfast?

Lin Feng said helplessly: "You really don't plan to give up, if you really find the Earth Dragon, your sandworm mining machine will be gone." ”

Fang Yan walked in the direction of the Temple of Earth without any care: "I can't find it, and there is no loss, I found it, isn't it right." ”

When everyone arrived at the Temple of Earth, Fang Yan finally understood why they felt like that when they talked about the Temple of Earth.

On the vast grassland, there is a pile of rocks piled up into the shape of a yurt, no more than three meters high, covering an area of less than a square circle, this small pile of rocks, is the legendary altar of the earth, and there is a god-level demon beast earth dragon sleeping below, no one will believe it if they see it.

Next to the stone pile, there is a huge hole in the ground, which was dug by the sandworm miner, and when I walked to the side and looked down, it was pitch black below, and I couldn't see the bottom, and I didn't know how deep it was.

Fang Fengbao stepped forward and said: "You don't believe it either, I didn't believe it at the beginning, when I heard those people say, I felt very emotional, I felt that the Temple of Earth must be extraordinary, after arriving here, I wondered if I had found the wrong position, if it wasn't for the barbarians saying that this was the Temple of Earth, we wouldn't believe it." ”

Fang Yan looked at the stone pile and said, "Is it possible that we are all in the wrong place, this is not the Temple of Earth at all, or that the barbarians have deceived you." ”

Feng Yu said: "Forget it, I have searched for this radius of a hundred miles, and I have found a lot of barbarians for interrogation, this is here, there will be no mistakes." ”

"Then wait. Fang Yan sighed, sat down beside the pile of rocks, closed his eyes and concentrated.

An hour later, the ground shook slightly, and the sandworm miner emerged from the hole.

Fang Yan stepped forward and sighed, "It seems that I was wrong, the legend of the Earth Dragon is just a legend after all, not a reality. ”

Senior Sister Hu said, "Then what are you going to do next?"

"Back to the Black Water and White Mountain, to improve our strength, we need to trigger a beast tide. Fang Yan looked in the direction of the mountain range with a solemn expression. "My original plan was to set fire to the mountain, and there are materials I need in the Black Water and White Mountain, and I hope it will be in time. ”

patted the sandworm mining machine, the big guy immediately started, and headed towards the black water and white mountain, Fang Yan jumped on the back of the mining machine, and the others also jumped up.

The speed of the sandworm mining machine is comparable to that of the scale horse, and it is not its strong point to move on the ground, but it is its own job to drill and mine, and after entering the mountain forest, the sandworm mining machine starts, and in an instant, it will disappear into the belly of the mountain.

I don't know how much the black water and white mountain range ups and downs, there are countless monsters inside, and there are countless treasures, just the edge area is already extremely sinister, and the bald city is only established in the edge area, and then go deeper, the outer edge is basically the lowest level of demon beasts at level six, the deeper you go in, the higher the level of demon beasts, the more dangerous it is.

Fang Yan's five people could only rely on the small number of people, and the five of them worked together to rush into the peripheral edge area, kill a sixth-level demon beast, snatch its territory, and hide it in the mountain, so that the sandworm miner kept mining in the belly of the mountain.

Although the grassland is wide and can run at will, it is the most dangerous, once it is discovered by the barbarians, it must be a thousand miles of pursuit and killing, but hide in the black water and white mountains, even if it is only in the outer area, it is impossible for the barbarians to search the mountains with a large army, but it is safer here.

In the cave, a space opened up by the sandworm mining machine is specially used by the Fangyan refiner, and the cave leads directly to the belly of the mountain, and the countless mining caves with forks are like a labyrinth.

The ten-meter-high refining furnace is located in the large array, wrapped in raging flames, the huge magic circle in the cave is engraved, and the spirit stones of six or seven grades are inlaid in the formation, and the spiritual light of the large array flows, and the rich spiritual power circulates in it.

In order to better exert the power of the large array, in this cave, Fang Yan also deliberately chose a small place with spiritual veins, and the large array could use the power of the spiritual veins to strengthen its power.

After refining the sandworm mining machine, Fang Yan began to prepare for refining a refining furnace that could be commonly used, to have the ability of Sumeru Qiankun, it can be large or small, and the space in the furnace must be large enough, preferably the refining furnace can be like the Demon Lin Sword, with growth.

There are a lot of requirements, and the conditions are naturally very harsh, in the list of materials given by Zhi Brain, after reading a beginning, Fang Yan could only give up, and instead lowered the requirements, not daring to ask for the full version, only to simplify the productionable version.

All the materials collected by the sandworm mining machine in five days, plus most of the materials carried by Fang Yan himself, have been put into it, so that there is the current refining furnace blank, as long as it goes through the last step of refining and warming in the large array, the production of this refining furnace can be completed.
