"You said that when the time for this jade slip is up, will we use another jade slip for two months?" Entering the stone house, Nayu suddenly said.

"No, this jade slip is a timing key, which is only valid for one month, and a jade slip can only open a stone house at the same time. Yun Yun said after throwing a jade slip over.

"Okay," Naita said, sensing that it was indeed the case.

After returning the jade slip, she took out the boxy refining furnace and set it on top of the formation in the stone house.

The "clang" of the stove landing sounded, which made Yun Yun, who had just put away the jade slip, stunned for a moment, and remembered an important matter.

"We don't seem to have the materials ready yet. Yun Yun said stunned.

"It's okay, I've saved enough materials to refine four or five divine weapons. Nai Yu said with a nonchalant face.

"How do you refine a divine spirit weapon in the first place, do you have the materials to refine an ordinary spirit weapon?" Yun Yun asked.

"No one is going to carry garbage with them!" Nayu said.

"Then you first explore this formation and see how it works, and I'll buy some back. Yun Yun said.

"No, there is an option to buy materials in the formation, but this price is a bit abnormal," Naiyu said as he manipulated the formation.

"I'd better buy it, let's not suffer this loss. Yun Yun sighed.

"Don't waste time, it's not for us for free, it doesn't matter what you say about eating a little! As he spoke, Naiyu bought more than a dozen pieces of various spiritual irons.

The one who delivered the goods to the door was still the ugly man who received them.

With the materials, they began their first attempt.

First of all, it is to remove impurities, which has Yunyun's knowledge reserves, as long as you have enough patience, there is nothing difficult.

"It's too hot! It's low! It's too low! No, it's too low! It's hot, it's a little hot. Yun Yun, who was commanding on the side, looked at Naiyu's clumsy appearance, and shouted with hatred.

Naiyu was so focused on the spirit iron that she didn't care about her mouth at all, but Yun Yun's guidance still affected her mentality, making this piece of spirit iron melt into a useless pool of molten iron under her irritable heat.

"What kind of method are yours? I might as well figure it out myself!How can this fire change its temperature so quickly and so accurately?" said Nayu, slapping the refining furnace fiercely.

"It should be that the fire is not enough, okay, you can practice more," Yun Yun muttered after being startled.

"Write it out to me!, stand aside and don't speak!" Nayu said, stretching out her hand.

"Okay," Yun Yun said after carving all the methods of refining the spirit iron she had bought on a jade slip and handing it to Naiyu.

However, when Naiyu tried for the second time, Yun Yun still couldn't hold back the paper talk.

This directly caused Nai Yu to slap the refining furnace with more force in a rage, causing the entire stone house to tremble, and the formation under it also flickered overwhelmingly.

"I beg you to be quiet!" looked at Yun Yun, who was shrunk in fright, and Nai Yu said as if she was about to cry.

After nodding, Yun Yun raised her hand and sealed her mouth, so that it would be done once and for all.

The later attempts improved slightly because Yun Yun turned on the silent mode, but without exception, they all failed to become scrap iron due to the long refining time.

"What a thing!, Grandma doesn't practice anymore!" Nai Yu shouted after punching the refining furnace.

Since she was a god emperor who had reached the pinnacle in terms of spiritual attributes, all the people in the entire mountain heard this piercing demon sound in an instant, and they were all shaken and defeated, and the pill or spirit weapon in her hand was defeated.

However, no one dares to complain, who makes the family a god emperor powerhouse.

"It seems that we haven't stepped into the heart of the refining path!" Yun Yun couldn't help but sigh.

"No! I want to try again!" Nayu said, pulling out a similar refining furnace.

"Don't try it, the requirements for the formation attainment in the back of the refining weapon are also very high, you start to lose your temper in the front, and there is no drama in the back. Yun Yun persuaded.

"Formation?" Naita said as he constructed a formation that was exactly the same as the hearth formation in an instant.

This formation is simple to say, but it is actually quite mysterious, and it is impossible for ordinary people to reproduce it in such a short period of time.

"Good guy, you don't have any patience at all, how did you learn the formation?" Yun Yun asked after being stunned for a moment.

"It's called genius. Naiyu complacently broke up the hearth formation she had constructed, because it was not connected to the main array, so it couldn't be used.

"Okay, I'll give you something good. Yun Yun said, burning part of the Heavenly Array in her memory on the jade slip and handing it to Naiyu.

"What is this? mess!" asked Naiyu for some reason.

"There's a part of the book called "Heavenly Array", and that's all I can understand, so I've only memorized it. Yun Yun explained.

"What kind of heavenly array is not heavenly array, this intermittent is useless at all!" Naiyu was still very disgusted.

"Hmph, love or not!" Yun Yun said after tilting her head to the side.

"Hahaha! For the sake of this thing, I will reluctantly comprehend it. Naiyu said after putting away the jade slip.

Next, Naiyu began the cycle between buying materials and failing, Yun Yun saw that she was tired, and persuaded her to rest and rest, but she refused, like a demonic obsession.

Finally, on the sixteenth day, she successfully refined a piece of spirit iron, and although the elimination was not perfect, it barely met the minimum standard.

With the first success, she later mastered the know-how, and soon gathered enough materials to refine a high-grade spiritual weapon.

The second step of refining is fusion forging, which is simpler than the first step, because the main forging can be replaced by spiritual power compression.

This is linked to strength, and Naiyu's cultivation is naturally not a problem.

The second difficulty is depicted in the third-step formation, but it is difficult to resist Naiyu, who is a genius in the formation.

In the last step of quenching, Naiyu directly used the quenching liquid of the quenching god weapon, and it was very easy to complete.

"I have to say that you are also talented in refining weapons! even if your cultivation is far beyond the scope of refining high-grade spiritual weapons, it is too exaggerated to be able to refine them so quickly!" Yun Yun sighed as she weighed the high-grade spiritual weapon sword refined by Naiyu.

"Oh yes," Nayu said and fell asleep.

How could a God Emperor powerhouse need to sleep to rest, it was enough to see how much effort she had spent refining this sword.

"Whew, I had a nightmare," Naiyu muttered as she woke up two days later, patting her head.

"What nightmare?" asked Yun Yun, who had been waiting by Nayu's side, with concern.

"A big, big monster beast ate me!" Nai Yu said.

"What's there to be afraid of! Which demon beast dares to eat you, just let it open its intestines!" Yun Yun said.

"Yes, why should I wake up! Damn!" Nayu said viciously.
