Chapter 639: Smelting Ghost-Biting Gold

Thermal Erosion Leaf is a very rare material. Although it is less rare than the extremely precious natural treasure like Ghost Biting Gold, it is also quite famous for its difficulty to find.

However, it is basically difficult for both alchemists and weapon masters to use thermal erosion leaves, so although it is difficult to find, its value is not very great.

The thermal erosion leaf that "Lu Xin" took out now was what he asked for from Gui Houjiang. And the reason why he took out the thermal erosion leaf now is that he must use the thermal erosion leaf to melt the ghost biting gold.

The thermal erosion leaf has a very strange characteristic, that is, under normal conditions, whether it is soaked in water, chopped with a knife or an axe, or iced, it is no different from ordinary leaves, almost like ordinary things.

However, if the thermal erosion leaf encounters flames or high temperatures, it will quickly burst out with extremely terrifying power. Such power is vaguely similar to the burning power of flames, but it is not real burning, but a kind of corrosion.

Such corrosion can be regarded as pure corrosion in the initial period of time. In addition to its strong power, it will not cause the corroded objects to deteriorate. However, if the time is long, the corrosion power will deepen, and the corroded objects will not be able to maintain their original properties.

"Fortunately, I brought this thing, but it is really troublesome to use it." Looking at the leaves in his hand, "Lu Xin" was a little helpless.

Originally, he brought the heat erosion leaves as a special preparation for smelting ghost bite gold. However, this preparation was just in case, and he thought he would not be able to use it. Who would have thought that it would be used directly now, which was really dramatic.

However, as "Lu Xin" said, using heat erosion leaves is definitely not a simple matter. Because the characteristics of heat erosion leaves are strange, "Lu Xin" can only rely on its power for a short period of time. During that period of time, as long as the ghost bite gold is successfully melted, the next step he has to do is to find a way to separate the corrosive liquid formed by the heat erosion leaves from the ghost bite gold liquid. Because if he doesn't do this, once the corrosion power of the heat erosion leaves deepens, the ghost bite gold will deteriorate.

Such an approach can be regarded as extremely delicate control. But if you want to surpass the initial stage of the instrument fairy, it is only natural to learn such delicateness.

Without hesitation, "Lu Xin" took out a lot of heat-eroded leaves, calmed down, and then threw three leaves into the Suanni Ding.

The green leaves entered the cauldron and were immediately roasted by the high temperature of the sky-flowing fire in the cauldron. In an instant, the scarlet dots on the green leaves began to glow slightly, and then gradually grew larger.

Such enlargement seemed quite strange, just like a drop of ink was dotted on the rice paper, and then began to spread. So, you can see that the scarlet dots are getting bigger and bigger, and the scarlet on the leaves is more and more, and the green becomes less.

Until the whole green leaf turned scarlet, there was a light "bang" sound, and the heat-eroded leaf could no longer maintain its original shape, but turned into a pool of scarlet liquid.

"Lu Xin" standing next to the cauldron saw all of this, knowing that now was the time for the power of the heat erosion leaf to be used, so without any hesitation, he guided the scarlet liquid towards the ghost bite gold.

The scarlet liquid rushed to the increasingly reddish areas on the surface of the ghost bite gold, and this time, even with the hardness of the ghost bite gold, it finally could not maintain its original state.

So, it was seen that on the parts of the ghost bite gold surface stained with scarlet liquid, drops of red liquid began to condense and form, and then dripped into the sky and fire.

"It really works!" Looking at the dripping liquid, "Lu Xin" finally breathed a sigh of relief. If he couldn't even handle this first step, how could he forge the Xingtian Stone Sword?

However, soon, the next problem came again. The red liquid dripping and suspended in the Suanni cauldron certainly contained a considerable part of the ghost bite gold, but it also contained some heat erosion leaf liquid. Now, if "Lv Xin" does not separate these two red liquids as soon as possible, once the power of the heat-corrosion leaf liquid deepens, the ghost bite gold liquid will inevitably be corroded and deteriorated.

As a mature master of refining, "Lv Xin" has naturally considered this a long time ago. He pointed at the small ball of red liquid in the cauldron, and the red liquid suddenly jumped out of the cauldron and escaped from the scorching fire from the sky.

At the moment when the red liquid rushed into the air, "Lv Xin" shot out a stream of cold air and attacked it. Suddenly, the temperature above the liquid dropped sharply, and it was seen that green and gold soon appeared in it, which was a sign that the ghost bite gold and heat-corrosion leaves would return to their original state after leaving the high temperature.

Of course, with the change of color, the liquid also had the intention of returning to a solid state. But how could "Lv Xin" make the liquid return to a solid? So in this very short time, his spiritual power went everywhere, completely removing the green part of the liquid, leaving only the golden part. Then, before the liquid turned into a solid, the golden liquid fell back into the Suanni Ding.

Once the high temperature reached, the pure golden liquid began to slowly turn red, and naturally it was impossible to turn into a solid again.

"It's done!" Looking at the pure golden liquid in the Ding, "Lu Xin" knew that it was the pure ghost bite gold liquid that he had finally made, and it was what he really needed.

After wiping the sweat off his forehead, "Lu Xin" was slightly out of breath. When he looked at the ghost bite gold liquid in the cauldron again, which was probably only four or five drops in total, the excitement on his face turned into a bitter smile.

In the previous series of operations, "Lu Xin" had put a lot of effort. At that time, he not only had a high degree of concentration, but also had to control his spiritual power and flames step by step, without any mistakes. This brought him a lot of consumption and burden.

After such a great effort, he only got such a little ghost bite gold liquid, which was probably not even one percent of what he needed to forge the sword. So how many times does he need to repeat the series of actions just now?

"At least one third of the whole ghost bite gold must be melted, otherwise when the sword is really forged, the main material is not enough, then it will be over?" Talking to himself, "Lu Xin" suddenly felt a little painful. This time, forging the sword is probably much more difficult than letting him fight a battle. At this rate, he is afraid that it will take more than a month just to melt the ghost bite gold.

After searching in the storage bag for a while, a bunch of small jade bottles soon appeared on the ground next to "Lu Xin". These jade bottles looked exactly the same, and the number was probably no less than 300.

Picking up a jade bottle, "Lu Xin" poured out a warm jade-like yellow pill from the inside and swallowed it in one gulp. Suddenly, his slightly tired face was relieved a lot, and his spirits were much better.

There is actually only one kind of pill in so many jade bottles, which is the kind that can quickly restore spiritual power and refresh the spirit.

This time "Lu Xin" prepared so many of these pills because he had already anticipated the worst situation. Therefore, he prepared a large number of recovery pills to fight a protracted battle in this fierce ghost forest.

Moreover, this kind of pill is a good thing that has been refined after all, and the impurities and unclean things contained in it are much less. Therefore, not only is the energy inside more powerful than the magic crystal, but the risk is also smaller, and it is not so easy to produce magic obstacles.

After all, for something like a demon barrier, "Lu Xin" now has to pay great attention to it. Otherwise, if he falls into the illusion before he finishes forging the sword, not only will the sword be destroyed, but more accidents will also follow.

In this way, "Lu Xin" stayed in the center of the fierce ghost forest and easily spent a whole month. During this month, although he was not disturbed at all, he kept melting and refining the ghost bite gold liquid every day. This continued, not only did he consume a lot of energy, but his spirit was also a little weak.

Fortunately, he persisted and did not make even one mistake. Therefore, after this month, the ghost bite gold was reduced by about 30% to 40%, and it was much thinner than before. The ghost bite gold liquid suspended in the Suanni Ding was already as big as a baby's head.

According to "Lu Xin's" estimation, this amount should be basically enough.

Wiping the sweat from his forehead, "Lu Xin" could not get rid of the embarrassment and fatigue all over his body. He stretched out his hand and the thinned ghost bite gold flew out of the Suanni Ding. After using a trick to lower its temperature, "Lu Xin" collected it.

Then, "Lu Xin" let the ghost bite gold liquid float in the sky and began to sit cross-legged in meditation.

"Lu Xin" had to take a good rest for a while this time, because the ghost bite gold had been smelted, and he needed to proceed to the second step of forging the Xingtian Sword.

As the saying goes, haste makes waste, and "Lu Xin" understood this truth. So if he didn't take a good rest after a month of hard smelting, he couldn't guarantee that the second step would be carried out without deviation.
