Xue Tong refined the quality of hemp iron in five days, which made Wang Kedang secretly surprised, feeling that this child's talent seemed to be above Xiao Yu'er, and it was naturally very good for him to be able to receive more named smart male apprentices, so he continued to test Xue Tong.

The "Roar Tortoise Shell" is made of Howler Tortoise Shell, Silver Thread Bamboo and Hongyang Copper, and the three refining materials are bone, wood and copper, which is extremely difficult for beginners and is almost impossible to complete without a certain amount of talent and experience. Wang Kedang deliberately found a difficult problem to try how much potential Xue Tong had.

Ordinary roar tortoise shells don't have much protection, and the howler tortoises that have evolved into demon beasts and silver thread bamboos that are more than two hundred years old, with high-quality red sun copper, can be really used. Wang Kedang gave an ordinary turtle shell, Xue Tong walked around the inner market, silver thread bamboo and red yang copper are not out of stock, but the roar turtle shell is really no one to sell, fortunately, there are many other types of turtle shells, Xue Tong spent nine hundred spirit stones, moved back to the piles of turtle shells, snapping turtle shells, silver thread bamboo, red yang copper, and tried to practice.

The composition of the turtle shell is hard bone and a small amount of gum, the fiber of silver thread bamboo is more dense and strong than ordinary bamboo fiber, and the toughness is also enhanced by ten times, Hongyang copper can be melted with a lower fire temperature, the fiber and bone glue will not be damaged in the low temperature copper liquid, the mixed copper liquid is fused with the turtle bone in the container, and the tortoise shell is made after molding.

The flames in the refining room had been burning for seven days and nights, and Xue Tong was tired and fell beside the ding, surrounded by pieces of scrapped tortoise shells, some of which were charred and blackened, some of which cracked with a light touch, and some of which were tired and shrunk into a lump, and the shape of the armor could not be seen at all.

Xue Tong's face was completely black, the debris and soot in his hair were as much as a stove, and his body emitted a disgusting sour smell, he woke up in a daze, freshened up in the stream below the mountain, changed into a brown shirt, and regained his strength and returned to the refining room.

It's another seven days and seven nights, this time the tortoise shell looks obviously better, the tortoise shell is a half-body style, protecting the torso and upper arm, about half an inch thick, the surface is a faint red, like brushing a few copper powder, a line of silver bamboo fibers, densely distributed on the tightly glued together pieces of turtle bones.

However, the force of the tortoise shell is not as expected, and the 400-pound boulder can smash the tortoise shell when it falls from a low place, and the protection performance is even inferior to the original tortoise shell.

At this time, the piles of materials bought had been used up, and Xue Tong went to the inner market to search for them again.

……

The quality of the tortoise shell is getting better and better, and the strength of five hundred catties hits it with a clang, and the tortoise shell is intact. The hardness of the shell of the turtle and the snapping turtle is not as good as that of the howler turtle, and if it is made of the hard shell of the howler turtle, the force can rise by two percent.

But this kind of tortoise shell is not satisfactory after all, and the protection power is only considered successful if it is added to three percent, in order to improve the speed of mana recovery, Xue Tong did not hesitate to consume more than a dozen medium-grade spirit stones, and practiced in the refining room day and night.

Five days later, Xue Tong took out the refined tortoise shell from the sand vessel, and the tortoise bone cut into pieces was fused into one, the outer layer was covered with silver thread bamboo fibers, and the gum and red yang copper filled the gaps between the fibers, and the whole tortoise shell was integrated, emitting a faint red light.

One hundred, two hundred, three hundred, until the strength of eight hundred catties, the tortoise shell has traces of damage, the test of slashing and stabbing has also achieved a convincing effect, if this tortoise shell is in the secular world, the high protection is unimaginable, but in the Xuanmen, the power of a thousand catties is as easy as a hand, and the newcomers in the early stage of the martial arts may use this armor to defend themselves.

There are only two days left before the deadline, Wang Kedang is sorting out the refining materials in the warehouse, the Ding fire in the refining room next door has been burning for two hours, he learned from Xiao Yu'er's mouth that Xue Tong made several good tortoise shells in a row three days ago, and then disappeared for two days, and sat quietly in the refining room for a long time this morning, and finally lit the Ding fire.

Wang Kedang was a little uneasy, this was greatly inconsistent with his past style, he had always been a person who did not hesitate to kill, but now he was worried about Xue Tong, what if this kid refined the roaring turtle shell? Do you really want to expel him from Guanxiu Peak as he had warned?

"This son is crazy and hard, trying his best to make weapons, but he is quite similar to me!"

He even kind of liked this smart and hardworking guy.

Outside the refining room, Xiao Yuer pursed her lips and sat on the stone steps, rubbing her hands constantly.

Luck and fate!

Wang Ke thought to himself, if Xue Tong had the strength but no luck, and unfortunately refined the tortoise shell, then he could only complain that fate had not arrived and obeyed the will of heaven. Whether it is refining weapons or cultivating immortals, luck and chance are really extremely important things.

Wang Kedang calmed down his messy thoughts, lowered his head and continued to sort.

"Wow~" A loud roar came from next door, and the voice was full of ecstasy.

"It's done?!" Wang Kedang let out a long sigh.

"Hahaha", Xue Tong's wild laughter confirmed Wang Kedang's guess, he held a tortoise shell in his hand, and shouted loudly as he walked: "Uncle Wang, Uncle Wang!" ”

Xiao Yu'er jumped up and pounced, grabbed Xue Tong's shoulder and jumped and jumped, "It's good, it's done, it's done!"

The first time Xue Tong saw this strangely behaved uncle, Wang Kedang had unkempt hard hair, an indigo robe with burn marks and seven or eight holes, and a pair of blistered eyes under his white eyebrows, staring at the things in Xue Tong's hands.

"Uncle Wang, this roaring tortoise shell is refined." Xue Tong stuffed the tortoise shell into Wang Kedang's hand.

Wang Kedang spread the roar tortoise shell on the bluestone floor, and slammed several punches with eight or nine hundred catties of fist power, and the thick stone slab hit deep cracks, and the roar tortoise shell was still intact without any traces of damage.

"Hmm" Wang Kedang nodded, a rare smile on his dry face.

"The tortoiseshell was sent to you, and I went to the inner market to sell it, and I got some money back." After Wang Kedang finished speaking, he walked into his hut slowly.

……

Inner city.

Xue Tong found a branch and hung the tortoise shell on the side of the road, and after a while, two fifteen or sixteen-year-old boys surrounded him, "May I ask senior brother, is this a roaring tortoise shell?" ”

"Hmm"

"How do you sell it?" One of the white-faced teenagers asked.

"It's sold cheaply, and I only charge three hundred spirit stones."

"Oh, three hundred is still cheap, isn't it really a roaring turtle." The white-faced boy said uneasily.

Xue Tong took off the tortoise shell, "You try, cut a few knives, and don't need money if you cut it." ”

After several knife inspections, the tortoise shell only left a few extremely shallow knife marks.

"Well, yes, yes, I bought it!" The white-faced young man paid three hundred spirit stones.

"Ordinary roar tortoise shell, it's just an extra layer of protection, don't use it as a treasure armor." Xue Tong reminded.

"Uh-huh, I know, I know, the demon turtle's words are not this price, thank you, senior brother." The boy said as he put on the tortoise shell.

"Senior brother, can you practice another pair?" The tall boy was so anxious that he couldn't do it when he saw that the bargain was picked up by a white face.

"Howling turtle shells are not common, if there is one, I will help you refine a pair."

Xue Tong's heart blossomed, and his sense of accomplishment was bursting, and he immediately bought a frenzy in the inner market, and packed a variety of refining materials into small semi-storage bags, ready to do a big job.

……

Since then, Guanxiu Peak has become a frequent visitor, and Xue Tong has come every few days to help with chores, do Xiao Yu'er's work, and sometimes refine a few items alone to improve his skills.

Xue Tong's arrival greatly reduced the troubles of Wang Xiao and the others, and he was always happy to take on those relatively simple jobs, charging half of the fee, and taking the opportunity to practice various basic refining techniques a few times. Wang Ke was happy to see this, he and Xiao Yu'er were no longer disturbed by people who came to ask for help, and they could focus more on the high-level tasks under the sect.

The news that Xue Tong would refine the weapon gradually spread, and some shy disciples came to ask him to refine, but Xue Tong did not refuse, once the refining failed, the material of the refining tool was converted into spirit stones and paid on the spot, and there was no second word.

Xue Tong's refining technique is increasing day by day, and after three or four months, he has reached the level of six or seven points of Xiao Yu'er.

……

On this day, Wang Kedang found Xue Tong and threw over two kinds of refining materials, a carbon gravel and a tail of colorful feathers.

"Can you refine two things? A stone bowl is made of carbon gravel, and the seven-colored feathers of the colorful feathers are separated. ”

"Queling wants to use a special flame, the disciple can't do it yet, and the carbon gravel shouldn't be difficult." Xue Tong replied.

"Hmph, then you can try!"

The temperature was already very high, the carbonstone burned into a dark red, Xue Tong continued to increase his mana, and the flames engulfed the carbonstone.

The ink-colored gravel still did not melt, the body of the snake tripod began to redden, it kept shaking, and it made a buzzing sound, Xue Tongjing was naked, his skin was burned red by the heat, and he hesitated to fill up the mana.

Wang Kedang became more and more impatient, and finally roared out with an angry face: "What are you doing, stop!"

Xue Tong took away the flames and looked at the angry Wang Kedang in fear.

"I knew you were going to fool around, and if you burn it again, Lian Ding might blow up!"

"Yes, yes."

"You usually refine those things that don't enter the stream, but do you know how to refine this carbon stone? I didn't figure it out, I was really angry! ”

"Yes, yes." Xue Tong sweated on his forehead and bowed down.

"In addition to the techniques and refining methods, how much do you know about refining tools and fire refining? Lao Tzu came to tell you not to know the height of the sky, and if you come up, you will practice blindly!"

Wang Kedang roared for a while, his face gradually softened, his personality was irritable, but his heart was not bad, Xue Tong's sincere admission of mistakes made him angry for most of it. If Xue Tong's attitude was slightly wrong, Wang Kedang would most likely beat people on the spot, and then ordered Xue Tong to get out of Guanxiu Peak.

"Yes, the disciple is too anxious, Master Wang will talk about it."

"Three refining rooms, placed snake tripod, claw tripod and crane tripod, snake tripod, crane tripod made of black light iron, carbon stone melting point is extremely high, and black light iron, you use black light snake tripod, how can you succeed in refining?!"

"The crests in the largest room are magical-level refining tripods, so they can withstand higher temperature flames."

Xue Tong listened with relish, and Wang Kedang was greatly satisfied with the appearance of being greatly educated and comprehending, and he suddenly rose up, summoned Xiao Yu'er, and lectured on the instrument scriptures for three days in a row.

Wang Kedang has been immersed in the refiner for sixty years, and the things he said are naturally not trivial, and even pointed out several flaws in the treasure book, Xue Tong opened his eyes, and wrote down the unknown places one by one, leaving them for future study.

Although Xiao Yuer has learned one after another, she has also listened to it with relish and benefited a lot.

At the end, Wang Kedang sucked up the carbonstone and threw it into the mantis, and a blue flame ignited, drowning the carbonstone.

"In addition to the Ding Gu, your flame is too rudimentary, the flame art is mostly born for attack, the generated flame impact is too strong, and the flame is as if it hit it, and this Nine Curved Flame, the fire power does not run around, it penetrates into the spiritual material, melts into it, and does not damage its essence, compared to the flames, it is simply a heaven and an underground!"
