The origin material of the big gun is there, and there is still a lack of auxiliary materials, Gu Xuan plans to use the iron dragon ancient wood as the barrel of the gun, and the purple electric dragon's bloodstone as the tip of the gun. It's just that the weight of the entire gun body is missing a piece of material. It seems that I have to go to the Taixu Chamber of Commerce.

The heaviest refining materials in the Xiuzhen Realm are the minerals that have evolved from the Heavy Xuan Stars, the Heavy Xuan Stars are a special kind of planet in the Xiuzhen Realm, the gravity on it is beyond the ordinary planets, dozens of times, or hundreds of times, or even thousands of times, people and beasts here are rare, if you want to dig out some materials, you can only wait for the lifespan of these planets to arrive, and when the star core is destroyed, a big explosion will occur, and then the entire planet will be destroyed.

After the Heavy Star is destroyed, some items will be left floating in the void, but these things left behind by the Heavy Star will not be able to be stored in the storage ring at all, and even if they are earned, they will also explode the storage ring. Only the Treasure of the Cave Heaven can collect these treasures. Powerful space immortal weapons can also be charged. Therefore, every time the Chongxuan Star was destroyed, the various sects in the cultivation realm would gather to compete with each other for the treasures left behind by the Chongxuan Star. It's a pity that these treasures are too heavy, and when refining magic weapons, a little bit will be extremely heavy. Generally, it is used to refine the formation flag of the Great Sect Protection Array.

After Gu Xuan came to the Taixu Chamber of Commerce, he directly took out the VIP token and came to the counter on the first floor, and said to the shopkeeper: "Get me a piece of the best Heavy Xuanxing material." ”

The shopkeeper swept the VIP token with his divine sense, and then said with a smile: "The distinguished guest is polite, I don't know what materials are needed?"

"The rest is not needed for the time being, you just need to get me a piece of the best material for the Heavy Xuan Star!" Hearing Gu Xuan say this, the shopkeeper was not annoyed, and said with a smile: "No problem, I will take the distinguished guest to the heavy Xuan Star material area now, but does the distinguished guest need us to transport it?"

Gu Xuan didn't answer, and followed the shopkeeper to a corner on the third floor, where dozens of heavy Xuanxing materials were placed, some were the size of a fist, and the largest was the size of a human head. Due to the small number of places where these materials are used, the people in the cultivation realm are collectively referred to as Chongxuanxing materials. Gu Xuan let out his mind and felt it, and finally chose a purple crystal the size of a human head.

As soon as the divine consciousness was wrapped and the mind moved, the purple crystal appeared in the Taoist Monument. The shopkeeper saw that the purple crystal was gone, a trace of surprise flashed in his eyes, but his smile was undiminished, as if he had known about Gu Xuan's treasure of the Cave Heaven for a long time.

"How many spirit stones?" Gu Xuan asked bluntly!

"Three million seven million high-grade spirit stones!" Gu Xuan waved his hand and took out a storage bag and gave it to the shopkeeper, and when he saw that the shopkeeper saw it, he put it away, said goodbye, and went back to the cave he rented.

At this time, all the materials were ready, and one shook himself into the Dao Law Monument. Gu Xuan didn't want any accidents, although the rented cave mansion was under Gu Xuan's control, Gu Xuan was still not at ease. The Dao Law Monument is the place where he stands, and only by entering it can Gu Xuan be able to refine his weapons with peace of mind.

As soon as his mind moved, an iron dragon ancient wood appeared in front of him, and the rest of the materials were also stacked around, and the remnant knife immortal weapon appeared in his hand, splitting at the iron dragon ancient wood, although the iron dragon ancient wood was only thick at the mouth of the bowl, but there were many side branches. Only a sound of gold and iron knocking was heard, and the remnant sword immortal weapon was bounced back, and there was not the slightest mark on the iron dragon ancient wood.

Gu Xuan was a little dumbfounded, took out the blood axe, and chopped it, but the effect was not obvious, so he had to summon the primordial purple fire and burn it against a pole, but unfortunately it took a stick of incense to burn the skin of the ancient wood. It was too difficult to refine the spear barrel with the Iron Dragon Ancient Wood as the main body, so he could only put away the Primal Purple Fire.

For a while, Gu Xuan's face changed a little. In the end, as soon as he gritted his teeth, he used the iron dragon ancient wood as the barrel of the gun, and at most it was just a long time to melt. The primordial purple fire was released again, turning into a silk thread, wrapping the iron dragon ancient wood, and began to cut off the side branches.

A day and a night passed, and the iron dragon ancient wood also turned into a single stick, shimmering with a metallic luster. Gu Xuan also put away the leftovers cut off by the Iron Dragon Ancient Wood, especially the roots, the root system was not destroyed at all, and he didn't know if he could change it again and regain its vitality.

The Nine Dragons Furnace flew out of the body, turned into a zhang in size, put the iron dragon ancient wood main rod into it, and began to refine it. At the beginning, the purple fire covered the body of the Nine Dragons furnace, burning fiercely. Gu Xuan made eighty-one innate handprints, and a glimmer of light flashed on the surface of the Nine Dragons Furnace, and it was quietly calcined.

Seven days have passed in a flash, and the iron dragon ancient wood in the Nine Dragons furnace has almost been tempered, and the thick iron dragon ancient wood at the mouth of the bowl is only the thickness of an arm at this time, but if you look closely, you will find that there are some more golden stripes on the surface of the iron dragon ancient wood. As soon as his mind moved, Gu Xuan's small half of his body entered the Nine Dragons Furnace, and the Blood Pattern Mithril Stone, Purple Electric Dragon's Blood Stone, Ten Thousand Years Cold Iron, and Purple Crystal were also thrown into it. Soon, his own body was refined into a blood-purple ball, three feet in size.

The blood-streaked mythril stone also turned into a liquid ball, and the 10,000-year-old cold iron and purple electric dragon bloodstone formed a dark purple spear tip, which was octahedral, more than three feet long, and each edge had its own teeth and teeth, and the upper edge was perfectly integrated with the iron dragon ancient wood. The purple crystal is also integrated into the entire body of the gun, and a big gun is also beginning to take shape, and the next step is the blood refining.

Gu Xuan released his divine sense, dividing his flesh and blood ball into one hundred and eight parts, Gu Xuan was ready to depict the dragon devouring array on the formed big gun, based on his own flesh and blood origin, supplemented by the blood pattern mythril stone, the depiction of the formation is the last step of all refining weapons, the power of a weapon is not only the refining material, the most important thing is the burned formation. It can also be said that the strength of the formation is related to the ultimate quality of a weapon.

The Dragon Devouring Array itself is the evolution of the talent of the super mutant beast Blood Dragon, the strongest means of the dragon's blood clothes, and has the property of devouring all things, combined with the method of blood refining, it will definitely have a complementary effect. I just wanted to burn it on a spear, but the time to test Gu Xuan had come.

Gu Xuan took a deep breath, calmed his mind for a while, and began to concentrate his divine sense, slowly burning it on the spear. There must not be the slightest mistake in the meantime, this is also Gu Xuan's divine sense is powerful, if it is put on others, there is no need to think about it, there is only one way to fail. One by one, the origin of flesh and blood was treated as a rune liquid by Gu Xuan, and the runes of the Dragon Devouring Array were slowly burned on the big gun. With each rune burned, the spear changed a little more.

Three hours passed, and there were more and more runes on the spear, covering almost all the body of the spear. There are still the last eight runes left, and this gun can be completed, after such a long period of tension, Gu Xuan can feel that his divine consciousness is already in a state of withering, but the obsession in his heart forces him to persevere, and there are only the last eight runes left, and the divine consciousness controls the origin of flesh and blood and burns it towards the last tip of the gun.

The tip of the spear itself is an extremely hard material refining, and after the quenching of the primordial purple fire, the hardness has undergone earth-shaking changes. In this way, it is more difficult to portray Gu Xuan.

Another hour passed, and the last eight runes on the tip of the gun were finally carved. Gu Xuan's face was pale, his forehead was covered with a layer of sweat, but his eyes were full of excitement, he took a deep breath, and forcibly suppressed the tiredness in his heart, and the blood pattern Mithril stone liquid also flowed along the carved runes. Connect all the Dragon Eater runes. The newborn spear erupted with a blinding light. Filled the entire Nine Dragons furnace, this bright light was fleeting, and it was bland.

The Nine Dragons Furnace also trembled, and the primordial purple fire was also full of fire, as if the treasure was about to be born. Gu Xuan's divine sense sensed it and knew that it was done. After running the Yuan Soul Technique, he fell to the ground and fell asleep, and for a while, there was an earth-shattering snoring sound in the entire Dao Law Monument.

Gu Xuan's sleep was three days and three nights, and he felt refreshed after waking up. The whole body is comfortable, especially the spiritual aspect, and after feeling it, I found that the Yuan Soul Recipe has reached the perfection of the human soul. I don't know when I will be able to break through and be promoted to the realm of the earth soul.

As soon as his mind moved, a dragon pattern on the wall of the Nine Dragons Furnace emitted a dragon groan, spitting out a three-foot-long gun with the thickness of a child's arm, the body of the gun was dark purple, and the tip of the gun was with a trace of blood, flashing with cold light, which was fascinating. After the Nine Dragons Furnace spit out the gun, it spun up and shrunk like a fist in a few breaths. The primordial purple fire also drilled into Gu Xuan's body.

Gu Xuan felt the gun in front of him, and a sense of blood connection immediately appeared in his heart. Reaching out and holding it, the gun instantly turned into a foot long. There was a giant purple snake coiled above. However, when Gu Xuan arranged the Dragon Devouring Array, he deliberately turned his talisman into a purple snake and circled the body of the spear. Feeling the weight of it, it weighed 130,000 catties, and when he wielded it with Gu Xuan's current strength, it was a little difficult, but when he finished the wood building chapter, he thought that this gun would be wielded freely.

"From now on, you will accompany me to split the obstacles ahead, pour your prestige with the flesh and blood of the enemy, and the immortals will block the immortals, and the gods will block and slaughter the gods, and from now on your name will be the snake!" Gu Xuan stroked the snake spear, telling his ambition.

The coiling dragon spear seemed to feel Gu Xuan's mood, and it was also trembling, full of spirituality. As soon as his mind moved, the snake spear drilled into the Purple Mansion, stayed in the hands of Yuan Ying, and was raised by Yuan Ying. Yuan Ying was wearing a purple-gold battle armor, with a snake tripod in his left hand and a snake spear in his right hand.

Suddenly, Gu Xuan's face changed, and then he laughed, and a flash appeared next to the little hairy monkey, but he saw that only a thin layer of golden-red blood cocoons was left on the little hairy monkey's body, and the little hairy monkey's whole body was shrouded in a layer of purple halo, and one by one runes exuding an obscure atmosphere, drilling towards the little hairy monkey's body. Eventually, all visions vanished into thin air. The little hairy monkey's body moved, the little eyes broke away, raised his front paws and rubbed his eyes, saw Gu Xuan, and squeaked excitedly.

One turned over and jumped up, screaming at Gu Xuan, his eyes rolled, and he jumped to Gu Xuan's shoulder with a search of Gu Xuan's legs. The little paw scratched at Gu Xuan's hair for a while, looking at Gu Xuan holding a chicken nest head, the little hairy monkey happily slapped his paws.
