After handing over the spirit stone and getting the auctioned Haoyang True Thunder Wood and Cloud Boots, Zhang Yifan cautiously returned to his residence all the way.

After returning to his residence, Zhang Yifan took out the two treasures he had photographed and looked at them carefully.

Previously, when he delivered the spirit stones, he only roughly confirmed that there was no problem with these two treasures, and he didn't stay for a long time.

Looking at the Haoyang True Thunder Wood in front of him, the quality was slightly worse than his previous two, and it could barely be used as a substitute. If he didn't fail in refining the natal magic weapon by then, he could still use this spiritual material to refine the general magic weapon of the opinion thunder attribute.

Then he took out the Cloud Boots.

The cloud-stepping boots are light white, the boots are soft, and they seem to be made of a high-grade animal skin, and the surface is faintly cloudy, and the flow is smooth, all of which show the quality of this magic weapon.

Zhang Yifan was very satisfied with this magic weapon and had a strong interest in refining such a magic weapon. He was going to buy some spiritual materials, and when he had time in the future, he would ponder the refining of the lower body magic weapon or magic weapon.

He put away the two magic weapons and began to think about the preparation of spiritual materials.

These two magic weapons consumed a small half of the spirit stones in his hand, and the spirit stones on his body were a little insufficient, and he was also ready to buy the corresponding magic weapon refining methods, spiritual materials and the silver spirit silk, and there were many places where the spirit stones needed to be used.

Thinking that he still had a batch of magic weapons in his hand that he could not use, as well as Tao Rang's magic weapons, pills, etc., he was ready to secretly dispose of them in batches.

In the next period of time, Zhang Yifan inquired about the news of the thousand-year-old purple yin flower, tried to buy some refining methods for the magic weapon, and sold the excess treasures in his hand one after another.

Ordinary treasures are sold directly to underground shops or exchanged for some useful things directly from the exchange meeting, and valuable ones are sold through underground auctions.

In order to be on the safe side and to avoid being noticed by someone who cares, he is slower to deal with treasures.

After nearly a month, Zhang Yifan successively disposed of nearly half of the treasures that were useless to him, and harvested almost 200,000 spirit stones.

In addition, he also bought a refining method for the body magic weapon called the Wind Riding Belt, and purchased several magic weapon spirit materials for refining this magic weapon, spending a total of 130,000 spirit stones.

It was more than enough to use these spirit stones to buy a wind riding belt, but Zhang Yifan was also willing to spend spirit stones in order to improve his experience in refining body magic weapons.

However, he didn't plan to refine it now, firstly, he could not use it for the time being, and secondly, he himself was not at ease about refining the magic weapon in Xiong Chu City, and he was worried that it would be exposed, after all, Chu Xiong City had a Yuan Infant Stage cultivator.

He didn't feel that the concealment array he had temporarily arranged could completely cover up some of the abnormalities produced by refining the magic weapon, and in order to keep a low profile, he did not arrange a higher-level array.

Soon it was the day when Tianji Lou held an intelligence meeting in Jingya Xiaoxuan, and Zhang Yifan arrived at the location on time.

Jingya Xiaoxuan is hidden on the outskirts of Chuxiong City, not in the capital, and the location is very hidden, and Zhang Yifan does not know its specific location. He entered Xiao Xuan through a short-distance teleportation circle.

The protection and cover arrays in Xiao Xuan are very powerful, and they are specially aimed at Jindan stage monks, and they have a good defense against the detection of divine consciousness. With the strength of his divine sense, he couldn't detect more than ten zhang away, and of course he wouldn't do such a taboo thing, but he had a high opinion of Tianji Tower in his heart.

Zhang Yifan was led into a private room with the voucher and received a number of seventy-nine.

After inquiry, he knew that this was the number of the inquiry, and that there were more than seventy monks in front of him, and according to his previous experience, he would have to wait for more than three hours.

Zhang Yifan couldn't help but sigh that this Tianjilou was really popular, and then waited patiently.

By the time it was his turn, four hours had passed, and the waiting time was later than expected.

Without impatience, Zhang Yifan entered a room that was separated by only a small window under the leadership of the attendants.

What surprised him was that this arrangement was almost the same as the part inside the Heavenly Machine Tower he had encountered in the mortal world, the only difference was that there was a formation covering it, so that he could not detect the situation on the other side of the window.

If he wanted to say that the Heavenly Machine Tower in the mortal world had no connection with the Heavenly Machine Tower in the Immortal Cultivation Realm, he would definitely not believe it.

"What news do you need to ask for?" a low-sounding voice sounded.

"I want to know where I can buy silver thread?" asked Zhang Yifan.

After a while, the voice in the window sounded again.

"The news of where to buy the silver thread belongs to the C level of intelligence, and the method of purchase belongs to the B class of information. 5,000 spirit stones of the third class, and 20,000 spirit stones of the second class. ”

This is still really outrageously expensive, Zhang Yifan couldn't imagine that he would need so many spirit stones for one news. But the difference between the C-class and B-class information was too big, which made him hesitate.

"Why is there such a big price difference between C and B?"

"Silver Thread Spirit Silk is a very rare spiritual material, and it is very difficult to buy it, which is also the main reason why the purchase method is listed in Class B, and it is recommended that guests choose Class B information. ”

"Alright then, I'll choose B. ”

Zhang Yifan then handed out the corresponding number of spirit stones and put them in the window, and after a burst of light passed by the window, the spirit stones disappeared, and a jade slip appeared.

"Guests, please finish reading the jade slip here, and at the same time need to promise not to disclose this secret to a third party to know, if the news is traced by Tianji Tower, the guest will face the punishment of Tianji Tower, please note. ”

Zhang Yifan nodded, expressing his understanding of such a regulation.

Then he picked up the jade slip and began to examine it.

After seeing the jade slip, Zhang Yifan knew that this spirit stone was not in vain, and if he was allowed to buy it directly, the chance of being able to buy it would be very slim.

After carefully reading the jade slip and memorizing the contents of the jade slip, Zhang Yifan returned the jade slip.

"Where can I find the Millennium Purple Yin Flower?"

"Knowing where the news of the Millennium Purple Yin Flower is belongs to Class B intelligence, and obtaining qualifications and getting detailed information is Class A intelligence. 30,000 spirit stones of the second class, and 100,000 spirit stones of the first class. ”

Zhang Yifan was speechless for a while, he couldn't imagine that the news of this thousand-year-old purple yin flower was much more expensive than the silver thread spirit silk. He didn't have to get this elixir right away, so he gave up after thinking about it.

After getting the information of the silver thread from the Tianji Tower, Zhang Yifan began to continue to deal with the magic weapons and other treasures in his hand, and then began to collect a magical leaf called the silver mulberry leaf.

For three months in a row, he was mixed in the scattered cultivation of Chuxiong City, on the one hand, he was familiar with Chuxiong City, and on the other hand, he was also searching for the spiritual materials he needed.

Zhang Yifan also made friends with an old man who was quite talked about in the middle of foundation building, Lao Yin. Lao Yin was met by him at an exchange meeting, he was relatively easy-going, and knew a lot of refining weapons, talismans and other immortal cultivation skills, and was an experienced refining master.

Zhang Yifan had a very happy conversation with him, and he felt a little confidant, and Zhang Yifan secretly used the secret method of Miao Lian and did not realize that the other party was harboring evil intentions, and he formed some friendships after getting along a few times.

According to Lao Yin himself, he has been in Chuxiong City for a long time and knows a little about the underground shops in Chuxiong City.

Zhang Yifan was convinced of this, because it was Lao Yin who took him to search for a sufficient number of silver mulberry leaves these days.

In order to thank Lao Yin, he also gave Lao Yin a lot of spirit stones as a thank you, but he didn't expect that he didn't need it, saying that he wanted to refine the best magic weapon for self-defense, but he was worried that he couldn't refine it well, and wanted Zhang Yifan to give him some advice.

Just pointing out the refining tool, Zhang Yifan naturally responded without hesitation.

"Brother Yin, your magic weapon called Liuleng is very novel, each prismatic sword can be used as a complete set of attack magic weapons when taken out separately, and it can also be combined with each other to form a large prismatic sword or prism shield, which can be attacked and defended, which is wonderful. ”

Zhang Yifan listened to Lao Yin's introduction, and couldn't help but be amazed, feeling that this kind of refining method was very novel, which gave him a lot of inspiration, and couldn't help but be very interested.

"Haha, the old man has spent a long time pondering this, how about it, not bad?" said Lao Yin proudly.

"Well, if you refine it, you can almost refine it into a set of top-grade magic weapons. ”

"Oh, what Brother Li means is that if you refine it, it will be better than the old man's refining, and it will not be possible to achieve the inheritance of the magic weapon?" said Lao Yin with a look of disbelief.

"Hehe, since you say so, I want to try it, I don't know if Brother Yin can rest assured that you can refine it for me, of course, if the refining fails, I will make up these spiritual materials for you. "Zhang Yifan really wants to try refining it.

"I naturally trust Brother Li's refining technique, this is the refining method jade slip, so it should be paid to Brother Li in advance. ”

"Haha, Brother Yin is really refreshing, I'll study it first, at most half a month, I'll give you a set of six edges, what do you think?"

"Well, no problem, the old man will come back to ask Brother Li for advice in half a month. ”

Afterwards, Zhang Yifan took the refining method jade slip and two sets of spiritual materials, and returned to his residence for research.

Zhang Yifan, who had already advanced to the Great Grandmaster of Refining Weapons, had a thorough understanding of the refining method of the six edges in only two or three days, and this method was indeed very ingenious, which benefited him a lot.

However, he did not start refining immediately, but combined his understanding of the connection between the complete sets of magic weapons, and began to improve the refining method of the six edges.

Ten days passed on this research, and finally Zhang Yifan finally changed this set of six ridges into a lot more connected with each other. This is more flexible and requires less consciousness from the monk. The speed of combining into a large prismatic sword or prism shield is faster, and the power has increased by a few points compared to before.

Such a change can be described as huge, Zhang Yifan is completely able to refine this set of hexagrams with the Tiangong refining method, and enter it into the Tiangong Secret Dictionary, becoming a set of magic weapons named after Tiangong!

However, the time to promise Lao Yin was only two or three days away, Zhang Yifan only used the Tiangong refining method to strengthen the connection of the six edged swords, and the others still used ordinary refining tools, and finally took two days to refine the six edges once.

He injected mana to test it, and found that the magic weapon was indeed very good, and each prismatic sword had reached the top magic weapon level, and the combination had reached the level of inheritance magic weapon.

If it weren't for the fact that the spiritual materials for refining the prism sword were slightly worse, maybe each of the prism swords could reach the level of inheritance magic weapons, and the combination would be a set of top-level inheritance magic weapons.

However, Zhang Yifan just thought about it, such an attempt to replace spiritual materials is very labor-intensive, and it usually takes several months or even years to try, and it is by no means an overnight effort.

After the success of refining the six ridges, Zhang Yifan met with Lao Yin as agreed.
