Han Chen suddenly brightened.

The Hellstone is not a natural treasure, and alchemists basically know it. But it is precisely because of the small use that the impression is not very profound, and the unfamiliarity with the weak water environment makes it natural for Han Chen and the Two Realms to be unexpected.

He hurriedly started to dig up the mud under him, and sure enough, at a depth of one or two meters, he found a huge amount of red and white stony soil.

Shatter a piece of rock, grab a piece of it, and bounce a spark on it, and the stone immediately burns. Han Chen couldn't help but be surprised: "The book says that the Hell Stone is milky white, but the Hell Stone here is mixed with red, and the burning heat is higher than the book says, could it be that the characteristics of weak water have played an improving role?"

The Troll Ancestor was surprised, "You know the Hell Stone?"

Han Chen said disdainfully: "The books sold at the roadside bookstalls are all recorded, what is so strange." It's not a rare treasure. ”

The sense of superiority was swept away in an instant, and the Troll Ancestor said depressedly: "Damn, knowledge has been too overflowing these days......

Han Chen smiled: "It's because you're too outdated." ”

The Hell Stone was not much stronger than ordinary rocks, and Han Chen could easily obtain a large piece without using his true power. He unfolded the partition built into the Black Silk Ding, piling a large number of Hell Stones on the lower layer, while the upper space where the Adamantite Gold and the Xuanying Knife were located was still filled by the Nine Nether Fires.

Although it was far less powerful than the Nine Nether Fires, the high heat generated by the burning of more than a dozen tons of flint was enough to compare to the elemental fire condensed by the alchemist when refining the fighting weapon. Han Chen no longer needs to use Black Flame from time to time, he only needs to ensure a minimum of firepower. This external force greatly reduced Han Chen's pressure.

The endurance of the pure gold refreshed Han Chen's cognition of metal materials, and the red state remained for nearly three hours before it began to soften. And it took about five more hours to go from softening to completely melting.

Fortunately, he found a burning replacement on the spot, otherwise, with the remaining Senluo Thorn Pill, where would he be able to support him to complete the final tempering, let alone assist Xuan Ming to advance.

After melting the pure gold, the next step is naturally to refine it with the Xuanming Sword. The Hell Stone once again showed its usefulness, this step did not require too much use of Black Flame, Han Chen could slow down the solidification of the material with the natural flame of the Hell Stone, and he could put more energy into smelting the Xuanying Knife.

Although it was only a step-by-step process to restore the liquefied Xuanming Knife to its original state, after all, it was a combination of Adamantite Metal, an extremely tough material, and if something went wrong during the curing process, it would be quite difficult to make changes.

The materials used to construct the Xuanying Knife and the pure gold had already been fused together when they were liquefied, and now that Han Chen had removed the Nine Nether Flames, the temperature in the Ding Furnace had dropped greatly, and the flames of the Hell Stone were not enough to maintain the liquid state of the materials, and in just a few minutes, the liquid materials began to solidify.

Han Chen's technique immediately changed, and the structure of the Xuanying Knife in the Spirit Yuan was projected into the Black Silk Ding through the telekinesis.

The fighting weapon material fused with pure gold was immediately carried into the air by the mana, and according to the shape and structure of the Xuanming Knife in Han Chen's Lingyuan, the soft material gathered into shape little by little.

Almost every second, Han Chen was about to draw a spiritual power rune and smash it into the changing Xuanming Knife. The runes are printed on the Xuanming Knife, like the meridians in the human body, dense and irregular.

The restoration of the Xuanming Knife can be said to be quite smooth, but the Xuanming who wants to break through is not as easy as Han Chen.

The machine spirit is originally born based on the fighting weapon, and even if it is upgraded, it must be promoted first. However, Han Chen did not have the resources to improve the Xuan Ming Knife now, and Xuan Jing wanted to forcibly drive the body of the fighting weapon to advance with the power of the weapon spirit, which was tantamount to a tree wanting to grow branches first and then roots, which was really difficult.

Xuan Ming himself understands this, but it used to be a world-famous top-level fighting weapon, how could it be willing to be willing to be in the current realm? It is rare for Han Chen to refine the fighting weapon, this opportunity, it must seize it!

The revocation of the Nine Nether Flames also greatly reduced the pressure on the Xuan Netherworld and the Two Realms Ring. It is unlikely that the ashes will be wiped out, but it is just that he jumped over the body of the fighting weapon and directly advanced to the weapon spirit, and Rao is two realm rings do not have such knowledge and experience.

Xuan Ming's current machine spirit was reshaped by Han Chen's Great Universe Spirit Technique, whether it was the Two Realms Ring, Xuan Ming or Han Chen, all he could think of was to imitate the promotion of the human spirit element, and let Xuan Ming make the Great Universe Spirit Trick to break through the current level.

Xuan Ming has lived in Han Chen's spirit yuan for a long time, and of course he is no stranger to the Great Universe Spirit Technique, and without waiting for the body of the fighting weapon to be completed, it can't wait to launch the Great Universe Spirit Recipe Technique.

The vortex of spiritual power surged with the Xuanxia Weapon Spirit as the center, and the rotating astrolabe sucked up the nearby spiritual energy in large streams. Because of the existence of the star soul, the attraction of Xuan Ming actually surpassed that of Han Chen, the master!

It's a pity that it can't perform Han Chen's Heaven Devouring Skill, otherwise the effect will definitely be even more amazing.

If you change to a normal environment, with the effect of Xuan Ming's exercises, it is not impossible to accumulate the energy required for evolution, but this is a weak water world, and the energy mobility is extremely poor, and Xuan Ming's spiritual power astrolabe has not operated many times, and it will no longer be able to absorb a trace of spiritual energy.

Xuan Ming almost wants to go crazy. But there was really nothing it could do but wait for the aura to slow down.

In less than an hour, the body of the Xuanming Knife was reshaped!

Han Chen's fingers flicked one after another, and dozens of runes flew out of his hand. The mana runes combined into a circular light shield, wrapping the Xuanying Sword in the center.

A ray of light shot out from the rune light shield, and it was reflected on the Xuanying Weapon Spirit above, which was the signal of the Fighting Weapon to attract the Weapon Spirit.

Once he returns to the fighting weapon, Xuan Ming will be limited by the body of the fighting weapon, and it will no longer be possible to promote independently. At the moment, Xuan Ming hasn't even touched the edge of promotion, how can it be willing to return?

Feeling Xuan Ming's unwillingness, Han Chen sighed and comforted: "Forget it, now that the conditions don't allow it, why bother to be strong? Go back! There will be a chance in the future." ”

Xuan Ming was full of resentment, didn't say a word, just tried his best to absorb energy.

Han Chen said: "If you don't return to the fighting weapon, when the fighting weapon is formed, you will lose the dominance of the Xuanming Knife, and the gains outweigh the losses." ”

The surrounding energy is extremely thin, and Xuan Ming's efforts are a drop in the bucket. Knowing that there was no hope of advancement, Xuan Ming yelled angrily, had to stop the exercises, and flew towards the Xuan Ming Knife.

"Slow!" As soon as the machine spirit approached the fighting weapon, the two realms suddenly stopped.

Xuan Ming subconsciously stopped, and Han Chen asked, "What's wrong?"

The Two Realms Ring said: "I thought of a way to give it a try, but the safety factor is not high, and it is difficult to say whether it will succeed or not." ”

Xuan Ming hurriedly asked, "What method?"

"At the beginning of the establishment of alchemy, various alchemy methods were neither mature nor systematic, and many of the techniques used to build fighting weapons came from those ordinary craftsmen, and among the various techniques used by craftsmen to cast weapons, the most popular was the method of covering soil and smelting. ”

"Covering the earth for smelting?" Xuan Ming and Han Chen were both a little surprised.

For the history of alchemy, Xuan Ming and Han Chen are no strangers. The so-called "soil smelting " originally refers to the method in which human craftsmen will cover the surface of the weapon with a special layer of soil in order to enhance the performance of the weapon in the later stage of firing the weapon, and then continue the smelting.

It is said that the weapon made in this way has a high hardness on the outside and retains the toughness of the metal on the inside, which greatly improves the efficiency of the weapon, so it is a weapon casting method that is widely spread and is still popular today.

Later, early alchemists inherited this method, combined with some spells, and refined them into weapons with attached power, which was the prototype of fighting weapons.

The earth-covered refiner has been precipitated in the history of alchemy for a long time, and it was not until the rise of human civilization that it was gradually eliminated by various emerging alchemy. It can be said that this method of covering the soil refining is the originator of all fighting weapon refining methods, and it is also the most primitive and relatively self-contained ancient refining method. Its principle can be described as simple and crude, but the refining effect is not very stable, compared with the various kinds of alchemy that were broad and profound later, it is a world of difference.

The current conditions are lacking, and the two realms ring proposes to use the soil refining tool, which is really no choice.

Han Chen weighed it, shook his head and said, "No, no, no, I'm not familiar with this method, and it's very risky, if you don't get it right, it will destroy the body of the fighting weapon." Besides, this primitive refining method does not take into account the synergy of the instrument spirit, if the Xuan Ming cannot fit into the fighting weapon during the refining process, then it will be a big trouble. ”

Xuan Ming was silent. "There must be risks, but the higher the risk, the greater the chances. The earth-covered refining can compress a large amount of energy into the fighting weapon, firstly, Xuanming will need this energy for promotion, and secondly, the Xuanming Knife is fused with pure gold, and its strength should be able to withstand the turbulence of the fighting weapon's own cross-leveling. As long as Xuan Ming can carry the energy infusion, it is not impossible to break through the level barrier. ”

Han Chen thought about it and was about to refuse, but Xuan Ming spoke: "So far, you let me go home empty-handed, I am really unwilling. The fighting weapon is no better than other creatures, it can be promoted freely, it is not easy for us to improve once, I don't want to let go of this opportunity, so you don't need to say it again, just use the soil to refine!"

Han Chen said: "The fighting weapon is not an ordinary weapon, even if it is made by covering the soil firing method, the soil used needs to be specially made, where do you let me find the right soil now?"

The Two Realms Ring said: "Don't look for it, there are ready-made ones here." I looked at it with my spiritual sense and found these ...... under your feet The sediment at the bottom of the lake, which has been suppressed by weak water for many years, has high density and rich mineral element content, making it the best natural material for soil refiner!"

Xuan Ming hurriedly urged: "Then what are you waiting for?

Han Chen smiled bitterly a few times and said, "You are really stubborn, I have obeyed you." ”

Xuan Ming laughed: "I think this is the result of your influence. ”

"It's also planted on my head!" Han Chen reprimanded depressedly.

After discussing the refining process with the two realm rings, he simulated it in his mind a few more times, confirming that there was nothing missing, Han Chen's magic trick was certain, and said: "You go back to the fighting machine, immediately run the Great Universe Spirit Technique, and we will start immediately!"
