Unconsciously, a month has passed, and in this month, Yu Wenhao has basically not stopped at all except for stopping halfway to recover his very consumed divine sense.

And this month's harvest is also extraordinary, hundreds of yuan weapons are placed in the storage ring, there are all the best yuan weapons, and there are even several superb yuan weapons, but unfortunately for Yu Wenhao, these are of little value, even if they are exchanged for spiritual weapons, they are not very useful.

Walking out of the Yipindi Fire Refining Room, it was still the previous disciple on duty, and after seeing Yu Wenhao come out, the disciple immediately greeted him with a smile: "It seems that Uncle Shi has been able to skillfully refine Yuan Weapons, I don't know if Uncle Shi will go back to rest first, or continue to rent a higher-grade refining room?"

"Just help me rent the refining room of the Three Grades of Earth Fire. ”

Yu Wenhao was ready to start trying to refine the spirit weapon, and originally wanted to start refining the spirit weapon, but after a month of refining the yuan weapon, it is estimated that the spirit weapon should not be difficult to refine, so he simply directly used the three-grade earth fire, first refining the spirit weapon for a period of time, and then directly refining the medium grade.

"Three Rank Earth Fire Five Thousand Grade Spirit Stones for a month. ”

"Let's rent it for half a year first, here are 30,000 five-grade spirit stones. ”

"Thank you, uncle, please. ”

The disciple smiled after taking the spirit stone bag, if everyone was like Yu Wenhao, not only would he be able to complete his daily tasks, but the spirit stones he had been rewarded for several years would be as good as his sect, after all, there were nearly a hundred refining rooms within his jurisdiction, even if the spirit stones rewarded by others were a little less, but the accumulation was a lot of income, it seemed that he had really chosen the right choice to be here to be on duty before.

Under the leadership of this disciple, Yu Wenhao came to the refining room of the Sanpin Earth Fire.

Of course, the difficulty of refining the spirit weapon is not comparable to the yuan weapon, although Yu Wenhao is full of confidence after this month's refining of the yuan weapon, he still meditates in the room for a few hours and rests to adjust the state to the best, he doesn't want to end up failing in refining the spirit weapon for the first time.

Four hours later, Yu Wenhao, who was in high spirits, took out dozens of pieces of refined iron that were larger than the first Yuan Weapon Spear, which was of course not used to refine Yuan Weapons.

The refining of the spirit weapon is similar to that of the yuan weapon, except that there is more aura sealed in it or the power of the spell is greater, and it is no longer able to withstand it with ordinary materials.

This time Yu Wenhao is going to refine this spirit sword, the main material is still refined iron, but it is not directly refined with refined iron, but it needs to be smelted into iron essence first, and a piece of refined iron the size of a watermelon is only the size of a walnut after being smelted into iron essence, so even the value of the spirit weapon is much higher than that of the high-grade yuan weapon, which can be seen from the materials used.

Put dozens of pieces of refined iron into the big ding, and it didn't take long for the refined iron to turn into a pile of molten iron, and the speed was more than ten times faster than when using the first grade of the ground fire, which is also a major reason why Yu Wenhao directly rented the third grade of the ground fire, anyway, the temperature of the third grade of the ground fire is also much higher than that of the second grade of the ground fire, and it can save a lot of time when smelting materials.

The molten iron kept boiling in the big ding, and gradually decreased, after an hour, the volume has shrunk by nearly half, but it has not yet fully formed the iron essence, although during this time Yu Wenhao can completely ignore it and let the earth fire slowly quench, but he still watched the process of the formation of the iron essence intently, for fear that something would happen halfway.

A day later, the original molten iron has disappeared, covering the bottom of the big ding is a cake-shaped red discus, but it is a discus formed by iron essence, after the iron essence is formed, if you add some other materials to it, you can also improve the level and power of the spirit weapon, but this time Yu Wenhao has no such plan, in that case will undoubtedly increase the difficulty of refining, and the way of refining is still good step by step.

The sledgehammer and clamps placed in the third-grade earth fire refining room are the same as those in the first-grade refining room, but the grade has reached the middle grade spirit weapon, and even if it is directly placed on the ground fire and baked, it will not cause any damage.

Sandwiching out the cake-shaped iron essence, Yu Wenhao swung the giant hammer again, it was much more difficult to make the iron essence shape than when using refined iron, even if it had just been taken out of the earth's fire, because of the hardness, it would take ten times more effort to change its shape.

Fortunately, Yu Wenhao's current power is all released, even the best spirit armor can penetrate with one punch, how can the mere iron essence be compared to the best spirit weapon.

Half an hour later, a long sword with a glowing light appeared in front of Yu Wenhao, originally a tea time, this long sword had already taken shape, but in order to refine his magic weapon in the future so that he would not be empty and powerful and unable to take it out to meet people, Yu Wenhao spent several times more time slowly forging the long sword into his imagination.

Then Yu Wenhao injected spiritual power into it, but after more than ten breaths, the spiritual power could not be injected into it, Yu Wenhao was puzzled, it stands to reason that the spiritual power contained in the spiritual weapon should not be only so much, otherwise, in addition to being harder than the yuan weapon, how can the power be enhanced?

Suddenly, Yu Wenhao had a flash of inspiration, alas, maybe this spirit sword is going to become his first failure, because Yu Wenhao was refining a yuan weapon before, so the spiritual liquid added to it this time is still according to the proportion of refining a high-grade yuan weapon before, so it is impossible to increase the spiritual energy in it.

This is also because Yu Wenhao completely relies on the methods recorded in the classics to try to refine on his own, and other disciples will generally follow others to learn slowly, and after watching others refine these basic knowledge, they will have enough experience, at least they will not make low-level mistakes like Yu Wenhao when adding spiritual liquid.

There is no mention in the classic records of how much spiritual liquid needs to be added to each level of spiritual weapons, which requires Yu Wenhao to slowly explore it himself.

It's a pity that Yuwen Hao spent a lot of effort in vain, put the long sword that had been formed back into the big ding, calcined for about half an hour, Yu Wenhao added twenty drops of spiritual liquid to the ding, and after being absorbed by the iron essence, Yuwen Hao picked up the calcined and deformed strip iron essence again, directly injected mana into it, and then continued to inject spiritual power, sure enough, the spiritual power injected this time increased a lot.

Continue to put it into Dading, and then add the spiritual liquid again, until the eighth re-calcination added the spiritual liquid, Yu Wenhao's spiritual power injected basically did not increase, Yu Wenhao knew that it should have reached the saturation state of this spiritual weapon.

A total of more than 460 drops of spiritual liquid were added, which was seven or eight times more than that of the high-grade Yuan Weapon, and the spiritual power that could be stored in it had also increased by about seven or eight times.

This toss took Yu Wenhao more than three hours.

The deformed long sword was re-forged, and it was not until it was restored to its previous appearance that Yu Wenhao cast a soul locking technique on it, this time Yu Wenhao injected gold spiritual power into it, and the low-level gold spell Yu Wenhao would only have a golden needle technique, and Yu Wenhao could only seal the golden needle technique in it.

It took Yu Wenhao a day and a half to complete this spirit artifact, and after the mana was entered, the tip of the long sword immediately transformed into dozens of golden spirit needles, in addition to spending a lot more time, and after many rework attempts, those iron essences were finally not wasted.

Even so, the first spirit sword refined by Yu Wenhao was also available.

Then Yu Wenhao took out the same amount of refined iron for smelting, but this time Yu Wenhao added a small amount of purple gold steel to it, and after more than a day of refining again, another metallic spirit sword was successfully refined by Yu Wenhao, and took out two spirit swords and compared them, and the hardness of the newly refined spirit sword increased by at least a few percent, precisely because of the addition of purple gold steel.

It's a pity that the grade of this spiritual weapon is still only a product, and after refining more than a dozen spiritual swords and spiritual spears, Yu Wenhao began to try to use some special materials to refine spiritual weapons.

Yu Wenhao held a crystal-white bone spur about a foot long in his hand, this is the back spur of a third-order tiger shark, it is very hard, and it can be used to refine the tip of the spirit spear.

If the tiger shark backstab is refined into a spear tip, it has a spiritual power bonus of nearly thirty percent to the water spiritual power, and for ordinary Chongmai stage monks, the power of the spiritual weapon used is enough to determine the life and death of a battle.

Yu Wenhao opened a bottle of purple-red blood and dipped the tiger shark's backstab into it, this blood was taken from a three-grade amethyst blood python, which had a certain resistance to the flames.

A quarter of an hour later, Yu Wenhao took the tiger shark backstab out of the bottle, which was already covered with a thick layer of blood, removed Da Ding and directly placed him on the ground fire to roast.

In this way, the hardness of the backstab can be gradually increased by the high-temperature calcination of the ground fire, but the probability of being directly roasted by the ground fire will be much lower.

Half an hour later, Yu Wenhao took the backstab, and with a slight shock, the blood that had been roasted into a charcoal shape covered on it shook off, looking at the bone spurs that had turned gray in his hands, Yu Wenhao sighed, it seems that this time the refining was not successful, but I don't know if it was because the temperature of the Sanpin Earth Fire was too high, or the roasting time was too long.

Even if it is not calcined, or for a slightly shorter period of time, the backstab can still be used to refine the tip of a sword, but then the hardness will not be maximized.

Originally, Yu Wenhao was learning various means of refining, and failure was actually a kind of gain, from which he could gain more experience and progress.

Took out a tiger shark backstab again, and re-refined it according to the method just now, this time Yu Wenhao introduced his divine sense into it in the past three quarters of an hour, and felt that the density of the bone spurs was several times larger than before, and the color was still crystal white, and it seemed to be intact, in order to prevent the situation just now from continuing to happen, Yu Wenhao left his divine sense in it, observing the changes in the bone spurs.

After another ten minutes or so, Yu Wenhao suddenly felt that there seemed to be a trace of white smoke overflowing from the bone spurs, and hurriedly removed the bone spurs from the ground fire.

Peeling it off, the bone spurs basically still maintain their original color, but the strength has increased several times, and this time it is finally successful.
