After handing over all the ingredients of the Great Returning Pill to Yaozun, Yang Fan turned around and ran to the Refining Weapon Peak, he now wants to search for materials, advance the Xingtian body, and at least add some flying attribute materials to it, so that he can also travel in the vast sky with his feet on the giant lance in the future.

Golden Stone, Red Flame Stone, Obsidian, Ten Thousand Years of Silver Wood, Fire Yuan Crystal......

Yang Fan didn't even know any of the materials in the Refining Pavilion, but fortunately, there were stickers on them indicating the attributes and names, otherwise Yang Fan really didn't know what these materials were called and what they did.

For a long time, Yang Fan has never studied the refining weapon, he has a punishment heaven in a fight, he has a medicine venerable in refining, he really meets a powerful opponent, and he also has a holy weapon Ziyin, so he never thought of getting involved in the refining weapon, but he didn't expect to come to the refining pavilion today and fiddle with these stones of different shapes.

While flipping through the refining weapon, Yang Fan compared the ore at hand and began to think about what attributes to add to Xingtian's body.

From the last time he fought against the zombie king, Xingtian's biggest weakness was that he was not sharp enough, he didn't even break the defense of the zombie king from beginning to end, the reason why he couldn't break the defense of the zombie king, Yang Fan's true yuan force was too weak on the one hand, and the weapons he used were not sharp enough was also the biggest reason, it is said that some divine weapons were indestructible, even in the hands of mortals, they could easily break through the defenses of some high-level monks.

"Huh, black iron and pure gold, isn't this the material of the Zhentian coffin, how can there be another piece here?"

Yang Fan suddenly discovered that among the many ores, there was even a fist-sized black ore, with the words "Black Iron Pure Gold!" written on it.

Yang Fan hurriedly reached out and wanted to take it.

"I'm ...... So heavy!"

Yang Fan didn't expect this small piece of black iron essence gold, he couldn't hold it, you know, after he broke through to the foundation building period now, after the true qi in his body was transformed into true yuan, his strength had reached more than 10,000 jun, so to speak, he could now lift tens of thousands of catties of things with his hands, but he couldn't even hold this small piece of black iron essence gold now.

Yang Fan wondered, thinking that at the beginning, when Ziyin fell into a deep sleep, the Zhentian coffin could not be included in the body, so he had to carry it back to Yangjia Village, you know, the whole body of the Zhentian coffin is black iron and pure gold, it stands to reason that Yang Fan can carry such a large piece of black iron and pure gold, and now it should not be too difficult to pick up this fist and make a little black iron and pure gold, but now he ......

"Ziyin, why can't I hold it?"

If you can't figure it out, you don't want to think about it, with Ziyin, the Holy Spirit who has lived for countless years, on the side, asking her is better than looking for anyone, and her body is made of this black iron and pure gold.

"This piece of black iron pure gold is the material left over when the old master refined this Zhentian coffin, when the old master threw it here, black iron pure gold is the hardest refining material in the world, even if the ordinary spirit weapon is added to the weight of one ten-thousandth, it will increase its grade several times, so the black iron pure gold is the highest refining material, the reason why you were able to carry the Zhentian coffin body before, it is because the Zhentian coffin was refined by your blood, even if I fell into a deep sleep, you are still my master, so you can carry it, but you need to use brute force！”

"Then if I add all this piece of black iron essence gold to the Xingtian body, what grade will he become? And how are the weapons of the cultivation realm divided into grades?"

Regarding the classification of spiritual weapons, Yang Fan has never understood very well.

"Spiritual weapons, as the name suggests, are vessels or weapons with instruments, monks can only operate spiritual weapons when they reach the realm of contemplation, and the weapons of the cultivators are divided into six levels, such as magic weapons, spiritual weapons, immortal weapons, Taoist weapons, holy weapons, and artifacts, and each level is divided into lower grades, middle grades, The four grades of the top grade and the best, of which the magic weapon is the lowest level, the magic weapon may be refined from high-quality materials, but because there is no psychic, it belongs to a weapon without spirituality, so it cannot be called a spiritual weapon, the general Qi refining period monks (that is, innate martial artists) use magic weapons, Sikong Sheng originally used the open heaven slash belongs to the magic weapon, and the spirit weapon is the magic weapon after the psychic, after the spiritual weapon is psychic, once it is refined by the cultivator, it can be connected with the cultivator's mind, it can be included in the body, and a divine thought can be summoned out of time. ”

Zi Yin briefly popularized Yang Fan's basic knowledge of the weapon level of the cultivation realm.

Xingtian is a psychic magic weapon, but due to the limitation of the material, Xingtian is only a low-grade spiritual weapon, because his body is only a piece of extraterrestrial Xuantian, and no other attributes of materials are added to it, but the piece of extraterrestrial Xuantian that was originally refined Xingtian's body is also of quite good quality, so Xingtian is also considered to be a low-grade spiritual weapon, and the quality is relatively high.

"Oh my God, Xingtian is actually three steps lower than you!"

Yang Fan didn't expect Xingtian to belong to the lowest grade of the spirit weapon, no wonder he tried his best, but he couldn't break through the defense of the electric zombie.

"Then if I add some black iron and pure gold to Xingtian's body, what level will he rise?"

Yang Fan only wanted to know if Xingtian's body was malleable, and if he could, he wouldn't mind raising Xingtian's grade.

"Even if you add fingernails to his body, you can elevate him to the immortal level!"

Zi Yin's words were not shocking, and when she said this, Yang Fan's jaw was so shocked that his jaw was about to fall to the ground, and the size of his nails could make Xingtian cross a large class, which was simply incredible.

"Then let's add some black iron essence gold to Xingtian's body now, so that he can reach the immortal weapon level!"

Yang Fan began to YY in his heart, and began to fantasize that he was holding a fairy weapon to punish the heavens, slashing demons everywhere, and looking majestic.

"Cut! Let's not talk about whether you can drive the immortal weapon with your cultivation, the black iron essence gold is the supreme divine iron in the world, and the density is very large, and the fire of the cultivation realm can't melt it at all, so it is simply wishful thinking to use it to improve the grade!"

Ziyin's words made Yang Fan feel like he had been poured cold water, feeling like he had fallen from the clouds, guarding the peerless refining materials, but he couldn't use them, which was really depressing.

"According to what you say, this piece of black iron and pure gold is still useless waste?"

The peerless refining materials were placed in front of him, but he could only stare dryly.

"How can it be a waste, as long as your strength is reached, you will naturally have a way to use it, but don't think about this good thing at the moment!"

Ziyin could see that she, the little master, was a little anxious, just like a newborn baby who wanted to stand up and walk before she began to learn to crawl.

Zi Yin didn't tell Yang Fan directly, when he opened the Zhentian coffin to the Burning Heaven Realm, he would have a chance to melt this piece of black iron pure gold.

"Then you see, which of these materials should I choose?"

Zi Yin is a holy artifact spirit, and she is well-informed, Yang Fan feels it is necessary to ask Zi Yin to help him with ideas.

"Okay! In order for you to reduce your dependence on me in the future, I will raise the rank of this kid of Xingtian. ”

Ziyin Tai selected a few stones from the many ores, threw them to Yang Fan, and said, "Use these materials to rerefine the Xingtian body!"

Ziyin didn't elaborate, but just helped Yang Fan choose a few ore materials.

"Tungsten Steel, Red Blood Refined Copper, Deep Sea Mithril, Xuanlei Iron, Wind Source Stone, Heavenly Phoenix Essence Rock, Berserk Stone, ......"

Yang Fan checked the names marked on these materials one by one, and then according to these names, he started the properties of these ores, and he found that the materials selected by Ziyin were very strange, and even made Yang Fan feel a little messy.

Ziyin seemed to see Yang Fan's puzzlement, so she asked, "What is the most important point of a weapon?"

"It's best to be able to kill with one hit!"

Weapons are killing weapons, since it is used for killing, it is first of all required to be sharp, and the material is required to be harder and tougher, simply put, the sharpness of weapons is important, but if the material of the weapon is too poor, too brittle and not tough, such weapons are useless even if they are sharp, because in that case, it is too easy to break.

"What you said is right, but your horizon is still too narrow, do you think that if the same sharp, toughness of the weapon, if your weapon still has the attributes of speed increase, hidden, critical hit, and even the hit rate has been improved, then do you say that such a weapon is more sure to win the opponent?"

Yang Fan just said that it is just the surface phenomenon of ordinary weapons, in fact, the speed of weapons is also the key, as the saying goes, the world's martial arts are only fast and not broken, and the same is true for weapons, the faster the speed, the easier it is to kill the opponent, just imagine, if your weapon is faster than the opponent, and then use attributes such as hidden, critical hits and even hit rate, wouldn't it have a better chance of winning!

As soon as Ziyin explained this, Yang Fan immediately came to his senses and hurriedly said yes.

"You should carefully study the knowledge of refining, so that it will be beneficial to you in the future!"

In the cultivation realm, some great powers can more or less use refining weapons, alchemy techniques, and even some formations. Of course, there are specializations in the art industry, and in these aspects, Yang Fan is definitely inferior to those who specialize in cultivating weapons or refining medicine, but it is also necessary to understand it appropriately.

"Hey...... You're right, I'll take some time to study it during this time!"

There happened to be a book about refining in this refining pavilion, and Yang Fan had always disdained to study it before, so he hadn't read it.

There happened to be a furnace in this refining pavilion, and Yang Fan could just reshape Xingtian's body here, in order to ensure that there would be no flaws left in the refining process, Yang Fan decided to get some materials to try to practice his hands, and then officially reshape Xingtian's body when the craft is mature.

After selecting the materials, Yang Fan returned to the Elixir Peak, and after meditating in the Elixir Peak for three hours, the Medicine Venerable finished refining the Great Returning Pill, and when Yang Fan came to the side of the Medicine King Ding, a strong medicinal fragrance came to his nose.

After opening the medicine tripod, dozens of crystal clear, round and jade pills in the heart of the tripod were exuding a hazy mist, and the tempting aroma was refreshing.

"Is this the Great Return?"

Yang Fan pinched one out of the ding, put it in front of his nostrils and sniffed it, feeling the majestic medicinal power inside.

"Hehe, give the White Valley Lord five of them each, it should be enough for them to recover!"

Refining so many Great Returning Pills at one time, Yang Fan took out two jade bottles, filled each bottle with ten Great Returning Pills, and put the rest into a jade gourd.

After exiting from the Zhentian coffin, Yang Fan walked straight to the VIP ward, where two security guards were guarding the door.

"How are the two of them doing now?"

"Manager Qiao ordered us to only stay at this door and not to go in and disturb, so we don't know their situation very well!"

The two security guards dutifully performed their duties and stayed here exactly as Qiao Susu ordered, and did not dare to disturb the people inside.

"Alright, you go down, you don't need to guard here!"

After sending the two away, Yang Fan pushed open the door and walked in, and found Bai Jingwen and the two meditating.

"Doctor Yang is here!"

As soon as Yang Fan entered the room, Bai Jingwen knew that he was coming, and immediately retreated from meditation.

"Da Huandan, I have already refined it, and I am worried about the injuries of the two seniors, so I hurriedly sent it over!"

"Yang Xiaoyou bothered!"

As soon as he heard Yang Fan say that he was sending the Great Returning Dan, Elder Taishang also retreated from the state of meditation.

"The seniors are up because of me, and the juniors should do this!"

Yang Fan said, handed over two jade bottles, and gave one to each person.

Both of them were seriously injured, and they were also eager to heal their injuries with this big pill, so after the pill arrived, the two immediately opened the bottle and took it out.

"You refined this Great Dan?"

After Elder Taishang poured out a large pill, he looked at the pill in his hand in amazement.

"yes, what's wrong?"

Yang Fan thought that there was something wrong with his Da Huandan, so he hurriedly stepped forward to take a look.

Bai Jingwen saw that Elder Taishang's face was wrong, and hurriedly looked at the pill in his hand.

"This ...... This is the best of the best?"

Bai Jingwen was taken aback, and he only now understood why Elder Taishang had that expression.
