"It turned out to be a furnace of ice and fire, it seems that the owner of this cave is a master refiner, and he can actually create a furnace of ice and fire. ”

Song Jian was slightly surprised, he had seen information about the Ice and Fire Furnace in the library of Blue Mountain Academy, and knew the special nature of this kind of refining furnace.

The Ice and Fire Furnace, which is cremated and solidified by ice, is the most suitable for refining valuable equipment.

The inside of the furnace is a flame, and the outside of the furnace is an ice layer, and the equipment refined is in one ice and one fire, repeatedly tempered, and slowly formed, which can be twisted and turned, and can contain the true qi of the two attributes of ice and fire.

Refining weapons in the Forges of Fire and Ice will be slow, generally lasting more than a month, but the success rate of refining equipment will be relatively high, and the equipment will be very good.

Song Jian stood at the entrance of the cave and watched for a minute, and finally he decided not to do anything, and simply took the weapons in the stove.

Now that he has killed the ice frog and eaten the spirit milk beads, it can be said that he has a grudge against the owner of this cave, and he doesn't care about this piece of equipment.

Wanting to hit here, Song Jian pushed the ice outside the cave.

The ice was a little loose, like a portal.

As soon as Song Jian exerted his strength, the ice at the entrance of the cave shattered open, revealing a circular passage.

The passage is surrounded by thick ice, and more than ten meters in front of it is a furnace of ice and fire.

Song Jian walked along the passage.

The flames in the furnace jumped and jumped, making a popping sound from time to time, and the surrounding ice was slowly melting, and at the same time, it was constantly replenishing, maintaining the environment of this furnace of ice and fire.

The stove is in the shape of a square tripod, and next to the stove, there is a groove, which is in the shape of a dagger, but it is relatively short.

"It was meant to be a dagger, but this dagger looks like it's used for assassination," Song Jian muttered, and then looked into the furnace.

"Hmm, why is there nothing?" Song Jian was stunned for a moment, and then realized that the materials in the furnace were mainly color-changing stones.

The color-changing stone is a very peculiar ore, its color can change with the change of the surrounding environment, at this time these color-changing stones melt into water, sticking to the bottom of the furnace, at first glance, even with Song Jian's eyesight, can not be found immediately.

"In addition to the chameleon, there are also sharp gold and broken silver, and it seems that this master really wants to refine a dagger for assassination. The color-changing stone can make the dagger invisible, and the sharp gold and broken silver are extremely sharp ores. Hmm? There's also a pattern here, a tearing pattern? I see. ”

Song Jian nodded, he saw the refining materials of the dagger in the furnace, and already knew that this master's idea was to refine a sharp and highly hidden assassination dagger, and when he turned his head again, he found a formation pattern in that mold, tearing the formation pattern.

The tearing array is a kind of formation specifically used to enhance the lethality of the weapon, and after infusing the true qi, it can make the weapon have the ability to tear armor and muscles. This tearing pattern is engraved in the mold, so that it can be engraved on the weapon during the process of forming the weapon.

Of course, this is the easiest way to carve a formation on a weapon, and complex formations or advanced formations cannot be carved in this way.

Song Jian looked at the furnace again, it can be said that the effect of this weapon for assassination is absolutely good, its color can change with the changes in the surrounding environment, so as to catch the opponent off guard, and the materials used are very precious, the toughness and sharpness are also very good, plus the carving has tearing formations, it is almost a perfect assassin's dagger, but, I always feel that something is missing.

Song Jian circled around the stove and turned around for half a circle, "What's missing? Ah, by the way, there is a lack of spirituality!"

Song Jian knew that although this dagger had taken a lot of thought in the process of refining, from the ice and fire furnace, to the selection of materials, to the smelting, to the final forming, it can be said that the owner of the cave wasted a lot of effort, but the dagger refined, although it was good, lacked a kind of spirituality.

"Well, the damaged dragon soldier I got in Salamander Valley might be able to increase the spirituality of this dagger. Thinking of this, Song Jian took out the damaged dragon soldier from the storage bag.

This weapon is just the tip of a long sword.

"This dagger, although very ingenious, is just an ordinary weapon, and if you add this damaged dragon soldier, it should be able to play a good catalytic role. Song Jian no longer hesitated, and threw the dragon soldier in his hand into the furnace of ice and fire.

However, to Song Jian's disappointment, the dragon soldier who threw it into the furnace did not react at all.

"No, although this furnace of ice and fire has the characteristics of cold and heat, its power is too low to smelt this strange weapon. Forget it, I'll just throw it in it and refine it for a few days. ”

Song Jian no longer bothered about the Ice and Fire Furnace, and returned to the cave along the ice path.

Squeak was still lying on the stone platform with its belly up, and there was a lot of vitality around it, and it was obvious that this little mouse was going to evolve.

Song Jian was not surprised, after all, Squeak was a mutant spirit devouring rat, and its talent was far higher than that of the big head.

At this time, the demon beast Zhenyuan around the big head began to gather, slowly converging into the big head's body, its body seemed to have grown a little longer, and its golden back was also more solid.

Song Jian sat cross-legged and cultivated, what he needed most now was to stabilize his current realm, so that he could smoothly impact the one hundred and eighty acupoints.

Two days later, a muffled "boom" sounded.

Song Jian opened his eyes suddenly, and he immediately looked towards the sound, and the previously stable furnace of ice and fire became irritable at this moment.

"Boom!"

There was another sound, and the flames shattered the surrounding ice.

Song Jian jumped up, he looked at the big head and Squeak, the big head had woken up, and Squeak was still sleeping.

Song Jian picked up the squeak, threw it into the big head's mouth, and said, "Big brother, I'll go see what's going on." ”

The big head nodded, it was in a very good state of mind now, a live ice frog, so that its injuries were completely recovered. After adding more than half of the spirit milk beads later, it even made it climb directly to the peak of the initial stage of the Void Realm! If he met Xin Yong and Jiang Hongxue again this time, the big head would be completely sure of victory.

Song Jian ran back into the furnace of ice and fire, only to feel a violent aura running around the furnace, and he looked down to see that the damaged dragon soldier was jumping around the furnace.

Song Jian was depressed, it seems that it is impossible to refine this weapon now, and it can be seen that this damaged dragon soldier is very dissatisfied with Song Jian for putting it together with chameleon stones, Fengjin, etc., which seems to be saying, what kind of identity do I have, how can I put it together with these materials.

Song Jian had no choice but to quickly pick up the damaged dragon soldier and put it back in the storage bag.

"Shhh...... Hiss...... Hiss ......"

A serpent's cry sounded from the furnace.

Song Jian looked towards the furnace again, and this time, the metal ore solution, which was originally spiritual, had become a terrifying momentum.

"Hmm, I didn't expect this damaged dragon soldier to be so powerful, just putting it together with this solution can make the solution full of killing energy, it seems that its predecessor must be very powerful. Song Jian muttered secretly, and at the same time he realized that it was the time for the dagger to be released.

Song Jian opened the mouth of the furnace, and the metal ore solution in the furnace flowed into the mold on the side.

"Nourishing ......"

A burst of green smoke rose up, and the surrounding ice made the dagger condense instantly, and at the same time, a burst of light fell, which was a sign of the successful carving of the torn formation.

Song Jian picked up the dagger, the dagger seemed to be transparent, if you didn't look carefully, you couldn't see its existence at all, and a cold aura came from its body.

"Good dagger!" Song Jian couldn't help but admire, "It has the quality of a four-grade weapon! Since it was refined under the influence of the dragon soldiers, let's call it the Dragon Hidden Dagger." ”

The memories that Song Jian received were usually the elixirs, Ding furnaces, weapons, medicine strains, ores and other items, all of which were divided into nine grades, such as the Nirvana Pill and the Mighty Vajra Pill that Song Jian took, which belonged to the six-grade pills, as for the weapons, the best weapon Song Jian had ever seen was the Cold Water Sword in Chen Ming's hand, but that sword was just a nine-grade weapon.

"Four-grade weapon! This is probably the highest quality weapon I've ever seen. If I hadn't put in the dragon soldier, it would have been a six-rank weapon at best. Six-grade weapons, people who can refine six-grade weapons, can't be found in the Han Dynasty at all, even in the Iron-Blooded Empire, there are only a handful. Song Jian thought secretly in his heart, "Not good, since this person can refine a sixth-grade weapon, it means that his own strength is definitely not low, I should leave quickly to prevent him from returning!"

Thinking of this, Song Jian flipped his hand and took out a handful of fire phosphate rock from the storage bag and threw it all into the ice and fire refining furnace.

The fire swelled.

Song Jian ran back to the cave without looking back, and closed the door of the ice path.

The fire inside the furnace grew bigger and bigger, and the thick ice around it began to crack slowly.

"Click"

Cracks appeared on the thick ice.

Song Jian glanced at the cave, and when he saw that there was no good thing, he jumped into the mouth of the big head and said, "Brother big head, try to destroy it as much as possible, don't leave traces, and then, let's escape!"

The big head nodded, closed his mouth, and the golden demon beast around him burst out violently, its huge head turned, touched something, and immediately collapsed somewhere, the big head was like a dragon in the sea, constantly churning, destroying this cave, and there was no trace of it.

"Boom ......"

The ice outside suddenly burst, and the fire brought by the fire phosphate rock was too fierce, and the balance between ice and fire was shattered, and the entire thick deep pool of ice actually burst.

The big head did not hesitate any longer, twisted his body, got into the dirt, and then fled away.

At this time, in the Yanshan Mountains outside the Free City, hundreds of people shuttled between the mountains and forests from time to time, the goshawks overhead, the hounds on the ground, and the flavor-chasing birds in the forests all took action, and they had only one goal, that is, the treasure on Song Jian's body and the demon beast of the Void Realm!
