At the same time as creating sword moves, Lu Hao's sword-casting ability is also constantly improving.

For the ability of the skill type of sword casting, the focus is on the basics, so Lu Hao did not rush at the beginning, but paid attention to the tempering of some details, including the identification of materials, the changes of materials at different temperatures, and how to refine the materials.

At the beginning, Lu Hao refined an ordinary iron sword, this kind of iron sword is very simple, as long as it removes its impurities slightly, it can achieve the purpose of solidifying the material, but the same material is very fragile, Lu Hao's geocentric lotus fire is very strong, at the beginning, if you don't pay attention to it, you will turn a piece of refined iron into a pile of powder, but in the process of getting acquainted, Lu Hao has gradually learned to control the output of the geocentric lotus fire, which can ensure the fluctuation of temperature.

In the next few days, Lu Hao gradually mastered the fire, and finally refined the first embryo sword, but this embryo sword was long and ugly, and it was very fragile, and it was broken in half with an ordinary iron sword.

Lu Hao shook his head and smiled bitterly, continued to temper, making a little progress every day, and finally after a few days, his skills soared, and he successfully refined a good embryo sword, and then continued to polish, and finally refined the first sword in his life.

For the first sword, Lu Hao was very happy, although the grade of this sword was very rough, but he still couldn't put it down.

With the experience of the first sword, Lu Hao then refined the second, third, and fourth swords one after another......

In a month, Lu Hao refined more than 100 iron swords, among which there were a few ordinary iron swords, the impurities were removed very well, and the whole process was very smooth.

Of course, to have this speed, it is naturally thanks to the geocentric lotus fire on Lu Hao's body, otherwise it would take at least seven or eight days for an ordinary person to refine an iron sword.

After knowing the refining of the iron sword, Lu Hao began to set his eyes on the stainless steel sword, which was of a higher grade, and the refining was naturally more complicated and troublesome.

Lu Hao first cleaned up all the materials and finished products for refining all the iron swords, except for the first iron sword, the rest of the iron swords were all sold by him.

Nian Wen quickly sent the materials of the steel sword that Lu Hao needed to Lu Hao's mansion, this kind of steel is harder than the material of fine iron, and the impurities are also more fine, and it is very difficult to refine.

However, for Lu Hao, a beginner, he is full of energy, speaking of this kind of hands-on work, it is easier than comprehending the creation of sword moves, Lu Hao almost treats this job as a recreational activity, and casts the sword when he has nothing to do.

The refining process of the steel sword is the same as the refining process of the iron sword, at the beginning, the impurities can not be handled well, and sometimes the materials will be refined until they are scrapped, but Lu Hao has never been discouraged, and he has been refining, and three days later, he has successfully refined the embryo sword of the first steel sword.

After more than 20 days, Lu Hao finally mastered the refining of the steel sword by seven or eight points, which can be regarded as reaching a certain realm, and ten steel swords can be successfully refined from eight to nine.

Then Lu Hao immediately began to refine the Xuantie Sword, the refining process of the Xuantie Sword was faster than the previous two times, this process of casting the sword is not that the higher the grade of the sword, the more difficult it is to refine, as long as the basic experience in place in the front, the refining time will only get shorter and shorter, so Lu Hao successfully refined the first one in two days for the refining of the Xuantie Sword, and then refined more smoothly.

In the end, Lu Hao even refined a few famous swords in the Xuantie Sword, refining the famous sword requires some special materials, fortunately, Black Tiger City has a lot of money, and these materials can be purchased, but the price is expensive.

For the refining of famous swords, Lu Hao was more attentive, and did not dare to be sloppy at all, and finally succeeded in refining six swords and scrapped three, with a success rate of more than sixty percent.

However, the six famous swords that have been tempered by Xuanhuo are stronger than ordinary famous swords, and when he handed them over to Nian Wen to take them out for auction, they were all sold for sky-high prices, and he completely earned back the material fees.

After three months of basic sword casting, Lu Hao was finally ready to start refining his first magic sword.

The refining of magic swords is even more difficult, first of all, the materials are very difficult to get, and secondly, the requirements for refiners are higher, and there must be no mistakes at all.

As for the materials, Lu Hao handed them all over to Anniversary Wen, and after seven days, he finally bought three materials that could be refined from several surrounding big cities.

During this period, Lu Hao also frantically read books related to sword refining, and constantly improved his theoretical foundation.

Three days later, when everything was ready, Lu Hao began to refine the first magic sword in his life.

The materials prepared for Lu Hao in the anniversary article are blue-eyed gemstone crystal, golden incense stone, fire heart ore and black clay.

The blue-eyed gemstone crystal is the basis of the embryo sword, the golden incense stone is the substance to be fused in the embryo sword, which plays a role in solidifying and hardening, the fire core ore can be attached to the embryo sword, which can increase the attack of the fire attribute, and the black clay is the adhesive, which can continuously fuse the three, making the whole embryo sword more mellow and fused, and will not cause rejection and bursting.

These materials are very rare and require a lot of money to buy, so Lu Hao can't easily waste them, his chances are only three times, and there is not much time for him to return to the Nanling Sword Sect, it is estimated that after refining these three swords, he should also go back.

The first step in refining the magic sword is to dissolve the blue-eyed gemstone crystal, and the impurities in it must be removed first, and the more dangerous thing in this step is that the temperature of the Xuanhuo should not be too high, otherwise the blue-eyed gemstone crystal will be completely dissolved and become a mass of liquid, so it can only be scrapped.

The second step is to fuse the golden incense stone, this step requires meticulousness and patience, because in the fusion process, you need to continuously add black clay, which can make the golden incense stone better integrated into the embryo sword, if the timing is not good, it may make the embryo sword become very ugly, a convex piece here, a little dented there.

The third step is to fuse the fire core mine, and what you have to worry about in this step is the loss of fire attributes.

The fourth step is the formation of the most important embryo sword, which is complete fusion, and it is also the most critical step, which must rely on the refiner to control the Xuanhuo with a strong mind to refine the entire embryo sword from beginning to end.

After keeping all the steps in mind, Lu Hao began to refine.

In the first refining, Lu Hao was too nervous, and in the second step, he did not control the heat, resulting in the golden incense stone not being integrated into the embryo sword, but instead refining the embryo sword, turning into a puddle of blue liquid, and the first sword refining failed.

Lu Hao was not discouraged and started the second refining, this time he was more calm, and passed the first step, the second step and the third step smoothly, but in the fourth step, because of the loss of his mind, the two ends of the embryo sword were not symmetrical, and there was a situation where one side was sharp and the other was blunt, and it became a strange blade that looked like a sword but not a sword, and the second sword refining became a defective product.

By the third time, Lu Hao did not relax in the slightest during the whole process, did not make any mistakes in the slightest detail, and finally refined the first magic sword in his life!
