It didn't take long for Tang Huan to find five low-grade gems from the old blacksmith's room.

Among them, there are ink-black ink spirit stones, such as red fire marble stones, colorful rutile, shadow moon stones like crescent moons, and purple thunder stones that are like lightning.

Each stone has different powers, and when integrated into a weapon, the effects it can exert are also different.

Tang Huan only pondered for a moment, and then chose the fire marble stone.

When the fire marble merges with the weapon, the weapon can exude a scorching meaning.

If it is driven by the true qi containing the power of true fire, the enthusiasm of the weapon can be greatly improved, but unfortunately, Tang Huan does not have the combat skills to match this type of weapon except for the "Dragon Nine Style", otherwise, he will definitely be able to exert the power of the weapon to the extreme.

Among the five low-level gems, the strongest effect is the Thunder Light Stone, followed by the Rutile Stone, and then the Shadow Moon Stone, and the Fire Marble Stone can only be ranked fourth, only slightly stronger than the Ink Spirit Stone.

But even so, Huoyun Stone is also Tang Huan's most suitable choice now.

Weapons that fuse fire marble, real fire can also play an amplifying role, and weapons that can be fused with other gems must be cultivated to achieve the corresponding combat skills, otherwise, low-level weapons are at most stronger than ordinary weapons in terms of material, and the power they can exert will not be much better than ordinary weapons.

A good weapon also needs to have matching combat skills to exert its maximum power.

After thinking about it, Tang Huan had already brought the gem to the shop in front.

The "Dragon Nine Style" is not only a swordsmanship, but it naturally has to forge a sword to achieve it. Before using the fire marble stone, Tang Huan still decided to use a gem to practice well.

The fusion of true fire relies on the tenacious will and the bearing capacity of the body, and if it fails, the spiritual veins will be damaged, and the soul will be scattered.

Forging this kind of weapon that has entered the grade also has the possibility of failure, and the possibility is not small.

The more advanced the weapon, the more precious the materials used, and the more heavy the losses will be if they fail.

Some rare and exotic gems and iron ore, often millions, tens of millions, or even tens of millions of gold coins, add up, the materials of a weapon will cost hundreds of millions, if it fails, it is likely to forge a low-level weapon that is only worth a few hundred gold coins, then it is really bloodless.

If an ordinary weapon is not well forged, it can be rebuilt, and if a grade weapon fails, it will really fail.

According to the previous life, that is, in the process of fusing gems, the molecular structure of the main body of the weapon has undergone a wonderful change, and the gem fusion is successful, and the weapon is completely finalized. If it is reforged, even the most high-tier weapons will be no different from scrap metal.

Tang Huan has a deep understanding of this.

When he was in the "Divine Weapon Pavilion" Wonderful Weapon Hall, when he burned the sword blank to a certain point with real fire, he found that countless tiny holes appeared on the sword blank, just like the pores on the surface of the human body.

If the burn is excessive, the weapon's material will be damaged.

When those holes are expanding to the extreme, the gem juice must be smeared with lightning speed, allowing the juice to penetrate into those holes. It's not enough to just infiltrate them, you have to make them completely blend with the weapon material, and in this process, you must have a tacit understanding of true qi and true fire.

In the second round of assessment that day, Tang Huan performed very well, and the most important thing was to grasp the timing of applying gem juice just right.

However, if Tang Huan was asked to do it all over again, he wasn't sure that he would be able to do it that day.

The key to forging a grade weapon is to forge the weapon's blank to the point where it does not contain the slightest impurity, the second is to melt the gem at home, and the third is to see the timing of the gem being applied to the blank.

Fourth, in the process of fusing the blank and the gem juice, it is necessary to let the true qi and the real fire cooperate tacitly.

Moreover, there is no fixed technique or skill for this kind of cooperation, different weapons, different gems, and different methods of cooperation, even if it is a similar weapon that fuses the same kind of gems, it is the same, which no one can teach, and it depends on the experience and understanding of the refiner.

Finally, the quenching fluid should be appropriate, and the timing of quenching should also be accurate.

These key points, as long as there is one place that is not done well, will reduce the quality of the weapon, and even lead to the failure of forging the weapon.

And that's just the easiest way to forge it.

Some skilled refiners are said to have left grooves on the weapon instead of smearing the sap of the gem, which was melted and then re-condensed and finally inlaid into the blank, which is said to continuously improve the quality of the weapon.

This kind of method, Tang Huan had only heard the old blacksmith casually mention it, but he had never seen or seen such weapons.

"Let's try forging a long stick with the ink spirit stone first. ”

Tang Huan quickly calculated in his heart, some gems are suitable for all types of weapons, but some gems are suitable for forging into guns, some gems are suitable for forging into swords, and the "Thunder Light Stone" is suitable for most weapons, but relatively speaking, it is better to forge into sticks.

Now that he had made a decision, Tang Huan immediately took action.

In the blacksmith shop, there was soon a clanging sound, the blank that the boy had made before, it was okay to forge ordinary weapons, and it was a little insufficient to forge low-level weapons, Tang Huan had to reforge it, and when forging, with the power of real fire, completely remove the impurities in the blank.

"Bang!"

At noon, the blacksmith shop, which had been quiet for a while, suddenly heard a loud noise.

Tang Huan's face was pitch black, and the long black stick in front of him was constantly emitting black smoke, and countless cracks could be seen on the stick, dense, like a spider's web.

"Failed. ”

After a long while, Tang Huan picked up the long stick depressedly, and just shook it slightly, and the cracked long stick turned into countless large and small pieces and fell to the ground.

He originally thought that the "Mo Spirit Stone" had the lowest value, and even if it failed, the loss would not be large.

But he didn't expect to really fail in the end, and the reason for the failure was a little ridiculous, that is, he had been smearing the ink spirit stone juice for too long. Before the application was finished, the dense and tiny holes in the stick body exceeded the limit under the scorching of the real fire.

It wasn't until after the defeat that Tang Huan suddenly realized that he was forging a long stick, not a sword.

The length of the stick is several times longer than that of the sword, and the time it takes to apply the gem juice is also longer, and the timing of the application is naturally different from when forging the sword.

"Fifty gold coins are gone!"

Tang Huan muttered stupidly, the loss was not big, but relatively speaking, even this lowest-valued "Ink Spirit Stone" would require fifty gold coins to buy.

"Damn, try it all over again, this time use the 'Shadow Moon Stone' to forge a sword!"
