Qingxu Daoren's teaching method is very peculiar, and he actually took Lu Yu to the stove room next to the stove room on the top of Shihan Peak with his hands behind his back, which is the place where the fifth senior brother Zhu is afraid of using iron refining tools on weekdays, and the kitchen utensils and farm tools used on the peak in previous years, as well as the hot pot used by everyone to eat last time are almost all made here.

After raising his eyes and making a large number of circles around, the Qingxu Daoist grabbed out with a big hand, and easily took several things and put them in front of Lu Yu's eyes.

"Tonight's first lesson will teach you to discern! Good students look at these things and tell me what you have observed!" Flicking his sleeves and pushing these things forward, the Qingxu Daoist sat on the soft couch beside him, quietly waiting for Lu Yu's reply.

The few things that the Qingxu Dao people gave to Lu Yu were not even rare treasures, they were all picked up from local materials, a few stones, a few pieces of Zhu were afraid to use the remaining leftovers, and even a few things were actually ingredients for cooking!

Since it is a topic from the three elders of Tianji, it must not be as simple as what it sees on the surface, so Lu Yu stepped forward and carefully identified and touched these materials one by one according to the inventory in his mind, and after about an hour, Lu Yu was already clear about other materials, but there were still two stones, no matter how he observed them, the conclusions he came to were ordinary stones!

"This doesn't make sense!" Lu Yu thought very tangled in his heart.

"It's all about it, I don't have a word yet, tell you, that gluttonous old boy is very good at manipulating, if you don't sleep well tonight, I guarantee you won't be able to hold it tomorrow!" Qingxu Daoist smiled happily.

"Then I'll pick what I know first! These kinds of Qingmu stone, Xuanyang iron, pig iron ore, cabbage, pork, spices, and mud bricks, as for these three, I'm not sure! This one seems to be the legendary silk crystal rock, but I haven't seen it and don't dare to conclude, although these two pieces look like ordinary stones, I faintly feel that it's not that simple!" Lu Yu scratched his head and said.

"Well, it's quite sincere!Go back to the house and get a pen and paper, and write down these things by yourself!"

Preaching is a big deal, don't look at Lu Yu's usual hippie smile with Qingxu Daoist, but at this moment, he will definitely not discount the words of Qingxu Daoist. Extremely quickly went back to the room to get a pen and paper, and Lu Yu wrote down everything he knew according to what he had just thought.

Aoki stone, according to legend, is the carbonization of ancient wood into stone, and after ignition, it is the best fuel for mortal refining tools to make iron.

Xuanyang iron, high-quality iron ore, solid texture but difficult to smelt, the ordnance of the military department is mostly made of Xuanyang iron, if the sword is extremely sharp, if it is the backing, it is solid.

Pig iron ore, the most common iron ore in the mortal world, can be melted into molten iron when burned, and it is the basic raw material for making kitchen utensils, agricultural tools and other basic raw materials for life.

Cabbage, pork, spices, just make up the numbers! Cooking is okay, but refining utensils can't.

Clay bricks, made of clay and slightly burned, can make them quickly firm.

Silk crystal rock, the only raw material of the cold rain of the Tang Sect's peerless hidden weapon, is said to use an exclusive technique to slap the rock face, from which dozens of crystal lines as thin as a hair can be extracted! These crystal lines are bent when they encounter water, if they drill into the enemy's pores, as long as they encounter the blood in the body, they will spontaneously curl up and easily cut off the meridians in the body, even if the body refining is strong, it is unstoppable.

After Lu Yu finished writing this, he read it carefully again, and after confirming that it was correct, he sent it to the Qingxu Daoist with a little expectation.

After comparing the length of Lu Yu's answer to Silk Crystal Rock and several other things, Qingxu Daoist sighed and said: "In the end, it is a killing material, among all the materials, there are obviously many that you can answer better, but what you care about the most is these killing techniques!"

When he heard the killing technique, Lu Yu just nodded his head slightly, and quickly opened the topic: "Is it better to answer?

For example, this Xuanyang Iron, I was afraid that it would take a lot of hard work to get it back from the bottom of the mountain, because his cultivation was too low, and he couldn't turn the Xuanyang Iron, and in the end, it was the old man who gave him a trick, so this stone was just a waste residue that had been refined! Even if there was still a little remnant of Xuanyang Iron, it was basically useless!"

"Look at this silk crystal rock again, in fact, you don't need any Tang Sect secret method, as long as your ability is there, this kind of gadget can be solved at your fingertips!" After the Qingxu Daoist finished speaking, he pointed and lightly knocked on the silk crystal rock, Lu Yu only felt that after a very magical rhythm, there were about tens of thousands of crystal threads like hairs ejecting out! With a wave of his hand, a breeze was blown, and all the silk threads rolled up against the wind and shrank into small black iron beads.

"You can play with all of these, inject mana into them when you want to use them, and it will naturally straighten! This thing is endlessly useful, but remember not to hurt yourself!" the Qingxu Daoist told Lu Yu.

"Uncle Shi, is it possible to reveal the secret of those two stones now?

"Haha, you've only guessed half right! This one is indeed an ordinary time, but this one is ......" When the Qingxu Daoist said this, he suddenly pretended to be profound and stopped talking, just picked up this stone, rubbed his hands hard, and removed all the surface of the stone, leaving only the crystal like blood fairy jade in the middle.

"Warm sun jade, can almost be regarded as the most precious jade, I didn't expect this kind of jade to be born in such an ordinary stone!

"Got it? Discernment material is the first lesson I teach you, if you want to know what power is, you must first understand what you have in your hand, and when you know what uses these things have, you can find out how to use it!"

"I think, this is the end of tonight, you bring this piece of paper, the question just now, is still left to you, if you have new additions to these questions, write it at any time!"

Lu Yu was a little confused, even if you can say something like this, but what do you do with adding ingredients and ordinary Aoki stone to a pile of refining materials, is this a reminder that you need to pay for your tuition by cooking for the three elders?

Not to mention when Lu Yu fell asleep, before dawn that day, the gentlemen of the various peaks of Tianji Mountain rushed to Shihan Peak! When I went back last night, I thought that I could get the support of my master, but I didn't expect that the words of the old glutton seemed to be quite weighty, and even the heads of the peaks did not raise any criticism.

The glutton is worthy of the title of Bull Demon King, he actually doesn't know anything about refining the body at all, just his strong physique, he is born. When Yin Shi fell the door to the martial arts arena on time, all the disciples who were late would kill the mighty sticks twenty times each, and seal the meridians to resist hard.

Throwing a group of weight-bearing armor in front of everyone's feet, the glutton asked Lu Yu to show everyone how to wear these Raush things, since they are dressed, then hurry up!

"So, little cubs, listen to me! Now everyone put on their loads and come down the mountain with me!"
