Gu Tiande didn't seem to expect Zhang Lei to be so kind, and bowed down slightly in panic and said, "No, no, I'll just stand, Senior Brother Zhang can tell me if I have anything." Xiao Lao'er will do his best and will definitely do it as soon as possible. ”

Looking at Gu Tiande, who was a little trembling, Zhang Lei recalled the rules of the lower sect, it seems that the outer disciples do not have these obligations to the inner disciples, and this little old man is still a manager of a public supermarket or something. It seems that it should be the unlucky guy who came to the door that day, ruining the image of the inner disciple, and talking to him well can scare this old man like this.

"Okay, if you like to stand, just stand, I'm here mainly to find some metal materials, do you have them here?" Zhang Lei said helplessly. This little old man looks far worse than the old butler, and he can be scared like this when he speaks.

The wrinkles between the little old man's eyebrows wrinkled like buns, and he said with some doubts: "Gold, metal materials? Can you tell me what specific metal materials are? We don't have anything too advanced." ”

"It's the material used to make such a weapon, this shouldn't be too advanced. Zhang Lei took out a small standard sword issued by the sect and said to Gu Tiande.

Seeing the standard flying sword that Zhang Lei took out, Gu Tiande looked suddenly enlightened, and hurriedly said: "Do you want to try refining weapons? You are a medium-grade magic weapon-level flying sword, which is refined with iron essence mixed with a small amount of refined gold. The only things we can find here are refined iron ore and some worldly gold, and the rest can only be found in the Contribution Pavilion or Refining Pavilion of the Sect. But we have some basic refining books here, do you need it, senior brother?"

"Isn't there any refined metal?" asked Zhang Lei with a frown. This ore refining is too cumbersome and too time-consuming.

Seeing Zhang Lei frowning, Gu Tiande wiped the slight sweat between his eyebrows, bowed down again and said: "There is really no, senior brother, what is accepted here are some low-level disciples and registered disciples of the outer sect, and the harvest of going out to practice." Refining metals requires at least the cultivation of the late stage of Qi training, and such good things are generally sent to the Contribution Pavilion to change the sect contribution. ”

"Then you go get some ore and I'll take a look, and give me a copy of all the books on refining weapons. Zhang Lei waved his hand and let Gu Tiande go out, his trembling appearance looked a little bored. This refining book should be a book on metal refining techniques here, which has a certain effect on understanding the level of metallurgy here.

Close your eyes and feel the experience points constantly merge into the blood-colored vortex in the center of your eyebrows, this tiny vortex continues to expand, and the force of tearing at the free energy around your body continues to strengthen. The concentration of free energy around is not too high, but Zhang Lei can clearly feel that the blood-colored mist is mixed with free energy, constantly fusing and transforming, and the colorful energy is constantly being assimilated by the blood-colored mist, a kind of red strange energy.

This energy continues to assimilate the energy condensed by Zhang Lei's own self, and after the amount reaches half of the total energy, it begins to operate in the veins of the whole body independently, and with each revolution, the color of this energy will become more profound. The blood-colored vortex in the center of the eyebrows, after the addition of this crimson strange energy, began to rise and shrink, and then the blood-colored mist around the body suddenly accelerated and condensed.

There was a faint sound in the center of the eyebrows, similar to the sound of eggshells shattering, and then the whirlpool swelled violently, completely covering the entire space in the center of the eyebrows. Then Zhang Lei found that the free energy that had just been condensed was directly converted into the red strange energy autonomously.

Zhang Lei opened his eyes and tried to mobilize the new energy in his eyebrows, and the red energy obediently passed through the veins on his body and came to Zhang Lei's fingertips, and then the energy particles began to vibrate violently. A dazzling beam of energy quickly formed, and then Zhang Lei pointed to the ground, and the beam disappeared instantly. A strange smell of burnt fire came from the ground, and the skins and wooden floors of the ground, even the dirt and stones, were pierced by the beam. A black cavern the thickness of an index finger, unknown to know how deep, appeared silently on the ground.

This energy intensity has been significantly increased by a level, according to the Federation, that is, household low-frequency energy has been increased to domestic high-frequency energy. It seems that it is not impossible for this energy intensity to be raised to the military level.

A chaotic sound of footsteps sounded, and Gu Tiande, who had been away for a while, walked in with some registered disciples in gray clothes. For a while, some lumps of various colored minerals were piled up on the floor of this room, and Gu Tiande himself held three thick books and walked over to Zhang Lei.

"Senior Brother Zhang has been waiting for a long time, these are the three most comprehensive books in terms of basic refining that we have collected here. Gu Tiande sweated slightly, and bowed over with the book in his hand. Zhang Lei stretched out his hand to take the three books, looking at the paper books with the same thickness as some reference books. I flipped through a few pages, one was a reference book on similar materials, one was a basic method of refining weapons, and the last one was a general introduction to various refining schools.

Nodding, Zhang Lei stuffed the three books into the storage bag with satisfaction, and then looked at the various minerals on the ground. The lumpy ones still have some dirt and even some plant fragments in irregular shapes, and they look like the most primitive open-pit ore. There is no special tool for refining these things, there is no way to do it, pick a few pieces and go back to see them, first go back and study these books to see the refining methods of the indigenous people here.

Seeing Zhang Lei frowning and looking at these ores, Gu Tiande hesitated for a moment and took out a gray storage bag from his arms. I rummaged through the storage bag and took out a square wooden box of about fifteen centimeters. After a pause, he handed it over and said, "Senior brother, this is a little bit of vulgar gold that I have collected myself, can you take a look at it?"

Zhang Lei took the box casually, opened it and looked at it, where two pieces of refined golden yellow metal were placed. After Zhang Lei nodded, he threw the wooden box into the storage bag, and then rummaged through the pile of ore with a flying sword, picked a few pieces of ore that looked similar to natural metals, and asked Gu Tiande to find a leather bag to put on, and then threw it into the storage bag.

Zhang Lei shook off the dirt and plant stains on the flying sword, and said to Gu Tiande: "That's all, you can calculate how many spars you want." ”

"No need, no need, these are not worth much, when the little old man honors you. Gu Tiande hurriedly waved his hand, took a step back slightly, and said. Are these outer disciples often bullied by the inner disciples, how does this picture look like the plot in a TV series, it looks like ordinary people giving confessions to some bullies.

Zhang Lei swept his gaze and asked a young man who looked eighteen or nineteen years old, wearing gray named disciple clothes, and his eyes were slightly angry: "You say, how much are these ores and three books worth?"
