After Duan De fed Xiaobai, he went to the back kitchen to get some food, and sat in the yard while eating and drinking while waiting for Lao Dao to come back.

As soon as he was full of food and drink, Lao Dao came back, inadvertently glanced at the milk dog sleeping at Duan De's feet, and said: "It's gone, but it's not the demon pill period demon beasts you think of fighting each other, and some threats over there have also been dealt with by the way, don't you want to find the earth fire to try the refining weapon? There is a hole under the canyon over there that has the source of the earth fire, and the formation has been laid for you, if you have time to go over there and figure it out for yourself, you can ask me if you don't understand." ”

Hearing this, Duan De's eyes lit up, and he said: "Master is mighty, then I'll go over tomorrow and get it myself first, this material?"

Lao Dao seemed to be prepared, handed him a storage bag and said: "What can help you in the future is yourself, no one in this world can be relied on, work hard, with your age and qualifications, this achievement is average, and now it is still a dog's tail grass in the greenhouse, embarrassing and useful!"

Duan De didn't refute anything with this evaluation, after all, the old guy was from the past, Duan De should be regarded as an official in the cultivator world, a rich second generation or something like that, right?

The next day, I told the butcher to let Xiaobai follow him, but this little guy still refused! The first time he obtained the storage magic weapon, Duan De played with it for a while, this bag was a little simpler, there was only a space with a diameter of three meters, and Lao Dao lost some mortal-level refining materials and a small refining furnace in it.

Duan De returned to the bedroom and put the books on refining weapons and formations into the ring, and brought some clothes, as well as bits and pieces, the oil, salt, sauce and vinegar seasonings in the kitchen are indispensable, in the past, the amount of food used to practice was large but it didn't care about the taste, but now it is quite particular about taste, eating, Duan De estimated that even if he could not eat or drink, he would not forget to eat it. The people take food as the sky, and cultivate immortals until the most basic hobby is gone, so it doesn't matter if you don't cultivate.

Coming to the edge of the cliff, Duan De used a levitation technique to slowly descend, he was not familiar with the terrain, he was not willing to jump around with his physical strength, that would only appear on hot-blooded teenagers, and he would be exempted from this fake teenager.

Stopping all the way, the fog on the cliff was very heavy, Duan De also saw an elixir stabbing blood vine, which seemed to be the main medicine for refining Zhuji Dan, and the growth environment was indeed suitable for the growth of this thing, but he didn't pick it, there was no suitable container to load, it was a waste to pick it, there were many mortal-level medicinal materials on the cliff, if an apprentice-level alchemist came over, he would be overjoyed, Duan De didn't understand the value of these things, so he could naturally turn a blind eye.

The bottom of the valley has finally arrived, I am afraid that there are not two or three hundred zhang high, a lot of low plants, the ground is flat, a huge lake, the water vapor is very heavy, the sunlight can not penetrate in, the line of sight is only fifty meters away, the lake water is crystal clear, some unknown small fish, with the waterfall waves wandering, the sound of the valley bottom is much more than the top, it is simply deafening, after going around the cliff and the lake, I found the hole that the old Tao said.

Two people come to a high natural cave, the vines hanging on the top have been cleaned up, it is estimated that the old road is done, do not think much about it and hold Xiaobai to the cave, the east has been extending downward, it is very damp, bryophytes are all over the cave, enter twenty or thirty zhang to see the road clearly, the ground is quite flat, the middle is low and the sides are high, it should be eroded by flowing water.

Duan De casually threw out five small fireballs and rotated around him, his vision recovered a little, the ground had begun to dry, and there were no plants left, only gray-brown rock walls. Finally, the front of the open and flat, there is a fire light, and then walk a few steps to a relatively open underground space, the space is not large, the size of two basketball courts, the top has uneven stone stalactites of different sizes, a huge stone stalactite pillar in the middle of the space, it is estimated that the reason why this space did not collapse This pillar also played a great role.

The earth fire mentioned by the old Tao is behind the pillar, the ground has obviously been artificially leveled, a formation covers the three zhang land, and there is a hole in the center with orange flames, the size of a basin, and the flame is controlled to burn quietly at about three feet, which is the only light source in the cave.

Duan De put down Xiaobai, took out the resin lamp oil from the storage ring, and dug out more than a dozen oil braziers in the rock walls around the space, the whole space became bright, and in a corner Duan De found a crack formed by erosion, which used to be a waterway, and the air was blown out of the crack, this underground base was not stuffy, but the heat was fixed, although the earth fire was imprisoned by the formation, the heat was still quite high.

I went out to survey the surrounding environment, beat a few wild beasts, and brought them back to the cave to deal with them, this is Xiaobai and his rations, who doesn't have to worry, ten steps away from the cave is the big lake. He used the old way to arrange several simple formations at the entrance of the cave for his spirit stone to prevent the beast from entering by mistake, and a maze array inside to prevent himself from accidentally entering the formation without paying attention to Xiaobai. Duan De had already learned these mortal-level small formations a few years ago, but the old Taoist only gave him practice formations and didn't give him spirit stones.

Everything was ready, Duan De took out the small refining furnace in the storage bag, it was only the size of a palm, and the three legs and two ears were very exquisite.

After inputting true qi, it becomes a water tank, which is more than one person taller. Throw it on the ground fire array, the ground fire can just cover the entire bottom of the furnace, and the hot furnace is the first step. Duan De immediately took out the materials, mortal-grade iron, cold iron, purple sand gold, etc. were piled aside for easy use, and it was very embarrassing that there was no divine sense and could only be operated by mind, but there were four observation holes on the refining furnace, and the furnace could be seen clearly with the urging of true qi, so as to operate.

Duan De has long had a definition in his heart, since he looks like a butcher, then use the utensils used by the butcher as a magic weapon. The pig-killing knife is indispensable, with his current state melee flow is certain, the shape of the pig-killing knife Duan De feels that he has a good hand!

The first time I practiced the weapon, the preparation was quite sufficient, and when I lifted the lid of the furnace, a heat wave hit, and Duan De's body was really shaking, and the body was not very afraid of this temperature, but the hair was not good. The temperature of the furnace is enough, pick up a piece of iron and throw it into the furnace, cover the lid, and urge the furnace formation, the ruler of the furnace can be seen to turn red with the naked eye, and it will melt quickly, and it does not fall into the bottom of the furnace with the assistance of the formation, but is suspended in the furnace, the furnace has been embedded with spirit stones in advance, and there is no need to continuously input true gas, only when operating.

Regardless of the piece of melted iron, material purification is the basis of refining, there are few pure materials, any material needs to be purified or separated from other materials in the material before refining, Duan De successively invested more than a dozen different mortal-level refining materials, purified, cooled and set aside, until all the materials are purified, it can be regarded as the first step.

At this time, I don't know how long it has been, Duan De, who was exhausted, watched Xiao Bai sleep at the entrance of the cave, and the prey he prepared when he came had been almost eaten by Xiao Bai, the little guy ate a lot of food, anyway, he could eat food two or three times bigger than it in one meal.

Duan De once lamented that dogs in this world are not something that ordinary people can afford, no wonder there is not a single dog in the village. The puddle next to the formation is basically dry, and if he is not awake, Xiao Bai is afraid that he will starve to death or die of thirst, and when he comes to the entrance of the cave, Xiao Bai immediately stood up and circled him affectionately, and picked up Xiao Bai out of the cave, it is night outside, but it is still necessary to go hunting, and the belly and dizzy eyes of the cooing and dizzy eyes continue to urge the need for food.
