After these five days of continuous practice, Zao Wou-Ki's experience in refining weapons had almost completely been fused by Ling Feng, and at this moment, he didn't feel like a novice at all, but like a battle-hardened veteran.

The refinement and fusion of each material are becoming more and more skillful, and the operation is almost perfect.

As various materials continue to be injected into the Dan furnace, the color of the Dan furnace changes again and again, and each time a material is integrated, there is more of a simple atmosphere on the Dan furnace, which is very peculiar.

"Next up is the Ten Thousand Mother Iron Essence. "Ling Feng's decision to add the Ten Thousand Mother Iron Essence to the Dan Furnace was after careful consideration.

Because the usefulness of the Dan Furnace Dan Master and the Alchemist is not exactly the same, for ordinary alchemists, the Dan Furnace is only used for refining the Dan Medicine, and they will not usually take it out and use it.

However, the Dan furnace has other functions for the Dan Master, it must not only be used for alchemy, but also for the enemy.

Even, in ancient times, Danshi would not use other divine weapons at all, only using Dan furnace was enough.

Although Ling Feng hadn't thought of using the Dan Furnace against the enemy, using it at a critical moment could also have an unexpected effect.

After adding the Ten Thousand Mother Iron Essence, the weight of the Dan Furnace will definitely exceed 10,000 catties, and if such a heavy force is smashed directly, the martial artists of the Lingwu Realm will definitely die.

As for the strength of the Dan Furnace, Ling Feng was not worried, because the whole of this guy was composed of Golden Crystal Iron Jade, not to mention other materials, just Golden Crystal Iron Jade was something that even a martial artist of the True Martial Realm could not break.

Coupled with the ninety-nine eighty-one array patterns on it, they are not ornaments, they are the real power of the owner.

After carefully melting the Ten Thousand Mother Iron Essence, it was injected into the Dan Furnace as before, and it didn't take long for the entire Dan Furnace to become thicker and heavier, with weight, if Ling Feng hadn't prepared early and increased the output of True Qi, I am afraid that this Dan Furnace would have fallen into the Vajra Flame and burned to ashes.

Secretly breathed a sigh of relief, and sighed in his heart.

If it weren't for the Vajra Flame, I am afraid that it would be much more difficult to refine this Dan furnace, not to mention the ten thousand mother iron essence, just say that the phoenix blood stone is not something that ordinary flames can melt.

Next, he took the dragon pattern blood crystal that he had obtained with great difficulty, which was also the last material to be added to the Dan furnace.

However, the use of this dragon pattern blood crystal is different from the previous materials, and it cannot be directly melted with the Vajra Flame, because once it is melted, the dragon pattern on it will be destroyed.

And the reason why the dragon pattern blood crystal is precious is because this dragon pattern has a miraculous effect, and if the dragon pattern is destroyed, then it will not have much effect.

However, the specific method Ling Feng knew.

So the control dragon pattern blood crystal floated to the top of the Dan furnace, just touching the top of the Dan furnace, and then with the help of Vermilion Bird, a ball of vajra flames separated out and came directly above the dragon pattern blood crystal.

However, this fire eye did not directly press down, but slowly approached the dragon pattern blood crystal, however, this distance was a bit far, and it did not cause much damage to the dragon pattern blood crystal at all.

However, as the distance continued to close, there was a sense of fear in the dragon pattern blood crystal, and the stone slowly trembled.

Seeing this, Ling Feng's eyes lit up, and he continued to control the fall of the Vajra Flame, shortening the distance between him and the Dragon Pattern Blood Crystal.

After about a minute, the dragon pattern blood crystal suddenly stopped moving, but the dragon pattern on it seemed to come to life, scurrying on the dragon pattern blood crystal.

Suddenly, he found a breakthrough - the place where he came into contact with the Dan Furnace.

Then, the dragon pattern immediately rushed over in a panic.

Seeing the dragon pattern descending on the Dan Furnace, Ling Feng almost cried out in excitement in his heart, throwing away the blood crystal without the dragon pattern and withdrawing the Vajra flame.

However, this was not over, Ling Feng's heart moved, and this Vajra flame suddenly flew up, and it turned into a round fire cover that enveloped the entire Dan Furnace inside.

In the flash of his thoughts, a large pit of ten square meters and about two meters deep appeared on the ground, and Ling Feng controlled the flames to calcinate the Dan furnace violently, and at the same time took out the Extreme Yin Water and filled the big pit.

Suddenly, bursts of cold air spread, and in the blink of an eye, a layer of ice crystals appeared on Ling Feng's brow.

"It's such a powerful extreme yin water. Ling Feng's eyes lit up, and he saw the right time to suddenly withdraw the Vajra Flame, and the entire Dan Furnace was actually red under the fierce roasting of the Vajra Flame, but it had no intention of melting.

"Give me down. Ling Feng let out a loud shout, and with a press of his right hand, the red Dan furnace was forced into the Extreme Yin Water by him.

A large cloud of fog rose as soon as I heard the sound of "zi", but soon calm returned.

The quenching of the last step of forging is extremely crucial, and the quality of this step will directly affect the grade and power of the divine soldier.

The reason why Extreme Yin Water is called the best quenching solvent is not only because it has the attribute of extreme cold, which can instantly cool down the divine soldiers, but also because it is fire itself and will not cause secondary damage to the divine soldiers.

As we all know, when an object has an extremely high temperature, it will crack when it is excited by cold water, such as glass and ceramics, as long as it reaches a certain temperature difference, even if it is a metal.

The same is true for forging divine weapons, the temperature of the newly forged divine weapons is extremely high, and if you want to achieve a high level, you must cool down instantly.

Although there are a lot of extremely cold spiritual liquids on the Tianwu Continent, quenching with those things will cause irreparable damage to the divine soldiers, which may not be visible in a short time, but once the power it bears exceeds a certain value, it will shatter.

However, the Extreme Yin Water is different, it is the Extreme Yin that appears under extreme heat in the virgin million-year-old volcano, and it is also a kind of fire.

Using it to quench can not only instantly cool down the divine soldier, but also carry out secondary forging on the divine soldier, making the fusion of various materials more compact and tough.

With a big move, Ling Feng's Dan furnace flew out of the extreme yin water and landed in front of him.

This Dan furnace is more than one meter high, dark gold, surrounded by mysterious array patterns, giving people a simple and atmospheric feeling, the most eye-catching is that the golden dragon pattern jumps on it, lifelike.

And it also exudes great power.

"Congratulations to the master, refining the Dan Furnace that is infinitely close to the true artifact. Thirteen felt this Dan furnace for a while and congratulated.

"Is it just infinitely close to the true artifact?" If it were someone else and refining a divine weapon that was infinitely close to the true artifact, he would definitely be pleasantly surprised.

But for Ling Feng, he was a little disappointed.

You must know that the materials he uses are all high-quality, and the King Kong Flame that is famous on the list of strange fires is even more exquisite, and even the quenching is the best quenching solvent extreme yin water.

But even so, its grade was only infinitely close to the true artifact, and it couldn't cross that layer of boundaries and advance to the true artifact level, how could Ling Feng be satisfied.

However, Ling Feng also knew that it was rare for a Dan Furnace to reach an infinitely close to a true artifact in his cultivation achievements, even if it was Zao Wouji, he had only refined an ordinary spirit weapon-level Dan Furnace at the beginning.

Because the Dan Furnace is different from other divine weapons, there are many restrictions in the refining process, and it is difficult for even a refining master to refine such a high-quality Dan Furnace.

Moreover, the materials he used were all high-quality, and although he had not reached the level of a true artifact, refining the fifth-order elixir was not a problem.

Moreover, the Dan Furnace will advance with continuous alchemy, which is also incomparable to other divine soldiers.

After a little tidying up, Ling Feng didn't waste his energy on this issue, stepped forward, bit his finger and dripped a drop of blood.

The Dan Furnace refined using this method cannot be used to melt into the divine soul, but it can recognize the Lord, and after fusing its own blood, it will become a part of its own body and can be included in the Dantian.

Not only that, as long as it puts in a ball of Vajra Flame, it can also continuously refine its true qi in the dantian and make it more refined.

The blood dripped on the Dan Furnace, and it was instantly absorbed by him, and then the Dan Furnace was born a few times, and a feeling of blood connection appeared in the bottom of Ling Feng's heart.

However, he didn't rush to put it into the dantian, but walked to its side to pick it up to see how heavy it was.

But he soon discovered that the weight of the furnace far exceeded his expectations.

I used my strength to eat, and I couldn't shake it in the slightest, you know, my strength is infinitely close to 10,000 catties of power.

"How is this possible?" Ling Feng was shocked, he knew that the Ten Thousand Mother Iron Essence he was going to come was only ten thousand catties, even if he added other materials, it was only ten thousand catties, and although his strength was less than ten thousand catties, it was impossible for him to be completely unable to shake it.

Then, he used his true qi, and his strength instantly increased to fifteen thousand catties, but he still couldn't shake this Dan furnace.

"This ......" Ling Feng was completely shocked, he really couldn't imagine how heavy this Dan Furnace was.

"Not true. "Suddenly, there was a very faint energy fluctuation on the surface of Ling Feng's Magic Technique Dan Furnace, if it weren't for the fact that he was the owner of the Dan Furnace, I am afraid he would not have noticed it.

Following this fluctuation, he found that the source of the fluctuation was actually the eighty-one formation patterns on its body.

"Could it be that this formation pattern still has the effect of increasing weight?" Ling Feng couldn't help but think about it, and then tried to close these formations.

These formations are generally in an open state, and unless the master specially seals them, they will use the power of heaven and earth on their own.

And with the closure of these formations, the energy fluctuations on the Dan furnace were also gone, and then Ling Fengyou stepped forward, but this time he easily picked it up.

"Sure enough. "Ling Feng's previous guess was right, the reason why he couldn't shake it before was that those formation patterns played a decisive role.

"I don't know, if these formations can be applied to my Fang Tian Painting Halberd. "Now, the weight of Fang Tian's painting halberd is too light for himself, and he can't use it to exert his full strength at all.

If it can be applied to Fang Tian's painting halberd, even if it doesn't need to be reforged, it can temporarily exert its due combat power.

After calculating the time, it took ten days to refine the weapon this time, and there were still two days left before he left the customs, so he just used the remaining time to test these formations.
