The Animal Taming Festival was still going on, and Ning Feng had closed the door of the warehouse very early on, no longer looking outside, he knew that it had nothing to do with him for the time being.

Calm down, Ning Feng held a book in his hand, one finger thick, this is a "metal jade chronicle" given to him by Lao Wutuo, which records the basic information of various metal jade, most of which are very common, but for Ning Feng, each one is fresh.

Halfway to the cultivation world, Ning Feng's starting point was at least ten years later than others' starting point, he had to put in ten times the efforts of ordinary people to catch up, as long as he could improve, no matter what aspect, Ning Feng would definitely not let go. His state is still terrifying, with the support of the instrument, Ning Feng does not eat or sleep, painstakingly studies the materials of this house, notes down their respective characteristics and even the origin, and the origin of each place especially makes Ning Feng's heart move.

Normally speaking, Ning Feng's current cultivation is a very hurtful thing for not eating or sleeping, he is not like other spiritual masters who have cultivated for decades or hundreds of years, he has forcibly turned into the sea, and his body's adaptability to the strength of the instrument is much inferior to that of people. But Ning Feng didn't care about this, he just knew that he had infinite energy with his strength, so he couldn't slack off.

For more than ten days, Ning Feng was almost familiar with the materials in the house, and Ning Feng attached great importance to some soul-level and phantom-level materials with relatively strong strength. These days, Ning Feng also made a major discovery, there were no Xuan-level materials in this room, except for a long strip of gray metal, the rest were phantom-level, or even soul-level materials.

Why is this so?

As the power infiltrated more and more experienced, Ning Feng discovered a strange thing, some Jin Yuan Shi Lu was born with concealment. They exist in the material, but they are difficult to detect easily, and after thinking about it, Ning Feng understands that this is not the embryo of a skill of a spiritual weapon?—— secret weapon.

This hidden weapon is just not a flying arrow or a barrel of sand, but with other materials, it can really achieve the stealth of the spiritual weapon, which is much more clever than the traditional hidden weapon.

Ning Feng was deeply aware of the profundity of the refining world, and after the Jin Yuan Shi Lu was well proportioned, the bodies that contained them were also quite exquisite. The simplest example, if you want to refine a sword, it is impossible for the entire sword to be filled with Jin Yuan Shi Lu, because Jin Yuan Shi Lu is a virtual thing at all, so you need a sword embryo.

This sword embryo is also very exquisite, it must complement the golden yuan stone spirit that is about to be contained, if this sword is good at attacking, it must be taken from the gold yuan in materials such as broken gold and purple gold, and its sword embryo also needs extremely hard metals such as Xuansmelted iron and red smelted iron. If this sword is used to make a flying machine, its gold yuan should come from the stone spirit of materials such as green cloud stone and mountain greenstone, and its sword embryo needs light and agile materials, which can reduce the consumption of the spirit master in the process of use.

Loyalty to the outside is one of the basic principles of refining.

Therefore, Ning Feng wanted a book of instruments too much.

Ning Feng stayed in the warehouse for more than 20 days, this experience was extremely rare for him, not only Hua Hai was also familiar with so many materials, and he was familiar with Jin Yuan Shiluo. This three-zhang warehouse is where Ning Feng's refining journey began.

Ning Feng hadn't forgotten to carve out the matter of Feng Lin'er, he had never had any experience, and it seemed a little tricky at this time. In the process of researching materials these days, Ning Feng discovered a kind of jade, called Youshan Xiuyu, which is soft, delicate and warm, and easy to carve a round state. Moreover, this stone is yellowish-white, similar to the skin color, and the original body is more than half a foot long, which can also meet the "hold in the hand".

Youshan is a good place rich in metal jade, and Ning Feng has found a lot of materials related to Youshan these days.

There was no longer any delay, but just as Ning Feng got up, there was a sudden clicking sound, "Mice also like this kind of place?" Ning Feng slowly walked towards the corner, and when he got closer, his eyes immediately widened, and the two words burst out-

Hammers!

The fire-colored lizard had already been ground into a golden lizard by the purple moon, Ning Feng drank this, and the hammer also raised his head, his eyes were as surprised as Ning Feng, as if he thought for a while before realizing that this swarthy and swarthy guy might be the very clean half-pulled master at the beginning.

However, the hammer didn't pay attention to Ning Feng at all, and continued to feast, Ning Feng was surprised to find that the hammer was holding a piece of broken gold and gnawing on it. Broken gold was the hardest metal in the room, but the hammer ate it with relish, and it didn't take long to eat a fist-sized piece clean.

The hammer straightened his neck, and he could hear a loud bang, which was considered to be clean, and the little guy touched his stomach, obviously not full, his eyes were dripping, and he had a goal.

Ning Feng was dumbfounded on the ground, the hammer had been in the Luo Sheng umbrella, and the Luo Sheng umbrella had been kept in his room, but he didn't expect this guy to find this place after looking for the taste. The hammer hasn't eaten for a long time, but Ning Feng never thought that this guy would actually eat metal!

Uh, and jade.

When Ning Feng looked at it again, the hammer was gnawing on a piece of red stone, which was also the hardest of the jade, a good and smooth piece, and soon he didn't know himself. Looking at the house full of food, the hammer is unrestrained, and it is very happy to eat and leak at the same time.

After eating the red rock, the hammer slipped and ran again, but before he reached the target, he was grabbed by Ning Feng's neck and lifted up, "What you eat is all soul-level materials, and the Jinyuan Shiluo has also been digested by you?"

The hammer obviously didn't know what Ning Feng was talking about, but looking at the look on his face, he hadn't seen the master for a long time, and he wasn't very happy after meeting, and he seemed to be asking for something from himself.

After thinking about it, the hammer suddenly opened its mouth, and the movement was very strange, like a vomit, and after a while, Ning Feng saw beads only the size of his finger belly falling out.

He was just surprised before, Ning Feng could only be said to be shocked when he saw this scene, the hammer actually stripped the Jin Yuan Stone Spirit!

This membrane peels off the golden stone like gastric juice, so that the hammer is not harmed, which is definitely the most expensive gastric juice in the world!

The hammer ate a piece of metal and a piece of jade, and spit out two beads, the color of which is somewhat similar to the material itself, it is like eating fruit, eating the flesh and spitting out the core......

Ning Feng took the Yuan Zhu and Lu Zhu in his hand, and felt the abundant power, they were no longer scattered inside the material, but were tightly wrapped in this strange membrane. Ning Feng was overjoyed in his heart, although he could sense the Jin Yuan Stone Spirit before, but if he really wanted to drive these things out and use them to refine the weapon, it would be extremely difficult, the Jin Yuan Stone Spirit was erratic and difficult to store, and he didn't know how much consumption it would be to absorb it with his own strength.

But right now, the hammer solves this problem, and when refining the weapon, you can use the power of the tool to cross the Yuan Zhu and the Lu Zhu, saving most of the energy.

While Ning Feng was not paying attention, the hammer shrank his neck and jumped on the ground, continuing to look for food, Ning Feng found that this guy likes to eat hard things the most, and it is only harder than the hardest. A soft and collapsed thing like Xiuyu soapstone is obviously not treated with a hammer. Seeing that Ning Feng didn't care, the hammer simply let go of his hands and feet, turning around in the warehouse, and sometimes even plunged directly into the metal pile.

Bones!

Ning Feng in the carving, from time to time he could hear the sound of beads rolling on the ground, and the hammer knew that Ning Feng wanted these, so he was very obedient to eat a piece and spit out one.

I don't know how many days I haven't eaten, and the hammer hasn't stopped after eating a dozen pieces, and with a little eyes in it, it has found a new target.

It was a purple jade, and it was also a phantom-grade material.

Ning Feng looked sideways, the hammer had been eating soul-level materials before, if he could spit out phantom-level Yuan Beads and Spirit Beads......

A neck up, a small piece of metal down the belly, I saw the hammer suddenly happy, the little paws kept pounding the ground, the face wrinkled, like a person laughing.

"Phantom-grade material!so strong?!"

The hammer then stood up on his legs, dancing for a while, the hammer touched his stomach, a great sense of satisfaction appeared on his face, and he walked towards Ning Feng with some ostentatiousness, "Where is the bead?"

The hammer looked like it was wrapped around me, and I opened my mouth halfway through, and at the same time, a plume of black smoke came out of my head.

"Phantom-level materials, it's really not ordinary. Ning Feng felt the difference this time.

One step, one step, one step at a time......

Boom!

Four on all fours, the hammer lies flat on the ground.

Stood up.
