By changing the shape of the cuttlefish sword, directly containing the copper and iron energy extracted from the copper and iron ingots, and slowly refining it, Xu Dao no longer has to immerse himself in the cave to refining the magic weapon.
It's just that in this way, the Squid Sword's refining speed of copper and iron energy will be much slower. It purely relies on the flying sword itself to swallow the copper and iron energy. It originally only took three or four days to complete the refining process, but now it takes
Less than half a month, or even more than a month.
Fortunately, this freed up Xu Dao's mind and allowed him to be busy with other things.
The only thing worth Xu Dao's concern is that after the cuttlefish sword turns into a metal gourd, it can still fly out to hit the enemy, but because the gourd shape is far less sharp than the sword shape, the speed will be compromised.
Even if he uses martial arts techniques, he won't be able to hold a gourd in his hand and engage in fencing with others.
However, these two points are not serious. When defending against enemies, the flying sword in the form of a gourd can still eject sword energy from its mouth and kill the enemy at a very fast speed.
Even because the gourd contains the breath of copper and iron that has not yet been refined, the sword energy will become more dignified and thicker when it is sprayed out with the breath of copper and iron, which may have unexpected effects.
It's just that this will lose the breath of copper and iron in vain, which is too wasteful. Xu Dao would not do it unless he was suddenly faced with an enemy.
As for the latter, when he needs to pretend to be a martial artist who wields a sword... Xu Dao looked at the iron gourd spinning in front of him, and a look of interest flashed through his eyes.
The next moment, the iron gourd swayed sharply again, its body elongated, and began to melt, becoming soft and collapsed.
If you look closely, you will see that the sides of the gourd become lighter and thinner, the body of the gourd evolves into a spindle shape, and the mouth of the gourd is entangled and condensed, as if it is about to turn into the shape of a sword hilt, but it is obviously about to change back into the shape of a long sword.
It's just that this change is too slow. It's better for Xu Dao to directly stretch out his hand and knead it into a long sword.
Because the gourd was still full of copper and iron energy, there was no need to transform into a long sword at the moment. After a little experiment, he ordered the flying sword to stop changing and return to the shape of a round gourd.
After touching the smooth skin of the gourd with satisfaction, Xu Dao casually hung it on his waist.
The copper and iron in the gourd's belly had not yet been digested, and it was difficult to shrink it into the belly. Naturally, he could only put it outside his body and carry it with him.
It turns out that the magical weapon refined according to the "Taibai Xijinjianwan Method" is not in the shape of a long sword, nor is it the gourd that Xu Dao just pinched, but an "alchemy liquid" with no fixed shape.
This is all because the main purpose of using this method to refining magical instruments is to refine Xinjin. Xinjin is Yin metal, which is the soft side of metal.
Compare lead and mercury. Geng gold is lead, thick and solid, while Xin gold is mercury, soft and amorphous.
However, due to the low level of the cuttlefish sword at the moment, although it can be shaped into various shapes such as sword shape, gourd shape, etc., it cannot be used to face enemies due to its slow transformation.
However, after Xu Dao condensed the Xinjin in the Cuttlefish Sword and promoted it to a real magical weapon, the sword could change its shape at any time, becoming soft or hard.
When he swings it out, it can fall from the sky like a waterfall in the Milky Way, easily cut off the enemy's head, and can also transform into a sword, hook and fork in the air, possessing various forms.
Even when the cuttlefish sword is used to refine other metals, it can directly melt into a puddle and directly wrap the metal and devour it, or it can get into the gaps and continue to eat.
However, due to the limitations of the method, even if the cuttlefish sword becomes invisible, it cannot be divided into multiple strands, and it does not have the magical effects of dividing the sword light into silk, or refining the sword into silk.
Fortunately, once the ritual ritual is completed and the whole body is purified into Xinjin, Xu Dao can try to mix it with Gengjin, cook the dragon and tiger, and get a sword pill, which will be of great benefit.

The above are the main reasons why when Xu Dao studied "Taibai Xijin Jianwan Method", he thought that this method was not like a sword method, but like an alchemy method.
This is because both in terms of form and the core function of the formula, it is like using a blast furnace to refine elixirs, melting gold and chemical medicine, and what is produced is also liquid metal.
Xu Dao touched the gourd on his waist and thought to himself: "This amorphous magic weapon is quite wonderful. From now on, whether you are pretending to be someone else or hiding your identity, you can change the shape of the magic weapon in your hand at will. There are many benefits."
Thinking of this, he suddenly began to ponder: "Which form can best exert the power of the cuttlefish sword?"
After thinking about it carefully, he remembered that the ultimate goal of the sacrificial refining method is to refine a perfect and stain-free sword pill.
According to the indirect description in "Taibai West Golden Sword Pill Method", the spherical shape, that is, the flying sword and jumping pill form should be the form that can exert the maximum power of the magic weapon.
But these things can be tested one by one later, so there is no need to rush to know.
After concentrating on sorting out the "Taibai Xijin Jianwan Method", Xu Dao hung up the gourd, bowed his head to the bones he had buried in the hole next to him, and then focused his gaze on the stone wall that had not yet been dug through.
Looking at the stone wall, Xu Dao patted the gourd on his waist and said suddenly: "I almost forgot, I still need you to dig the hole."
After saying this, he immediately took off the gourd from his waist and threw it forward.
Zizzi! The gourd immediately spun in mid-air and slammed into the stone wall. It was different from the previous long sword form. Now it was like a drill, driving hard into the stone wall.
In an instant, the scene was filled with dust again, and pieces of gravel fell off.
Because Xu Dao had refined the cuttlefish sword with ritual sacrifices, Xu Dao opened the tunnel at this time, and his speed was three minutes faster than before.
The stone walls blocking the road were also covered with cracks and holes blown by the evil wind. He estimated the time and thought that it would take half a day to completely penetrate them.
………………
time flies.
There was a click! A stone wall in the originally silent underground cave suddenly collapsed, revealing a person walking out.
Black light was flowing around him, and his body was covered with golden light. He walked out of the smoke and dust spotlessly, and it was astonishing that he had finally opened up a passage in the stone wall.
As soon as the stone wall was opened, the cave immediately sounded like the sound of wind roaring like tigers and dragons, whistling loudly, and the devilish sound penetrated the ears.
As soon as Xu Daogang appeared in the new cave, his expression suddenly changed.
The direction he was looking for was indeed correct. This place should be the core of the Dragon Vein Evil Cave, and its sinister winds were far more violent than the cave he came from.
Even though he practiced many mind-purifying spells, he was still in a daze for a moment and had to quickly suppress his restless heart.
Without thinking much, Xu Dao casually looked at the evil point in front of him. He quickly found a place nearby, and then sat up cross-legged to meditate.
His palms were slightly open, and several talisman coins that had been drained of spiritual energy fell down and were replaced by several new talisman coins.
Driving a flying sword through rocks would naturally consume a lot of Xu Dao's mana. Fortunately, he still had more talismans in his hand and was not afraid of the loss of mana.
But after all the hard work, he still stayed in the evil atmosphere. Both his spirit and body were a little tired, and he had to take care of himself quickly to avoid capsizing in the gutter later.
Finally, after refining the talisman money and taking the elixir, Xu Dao opened his eyes again and looked at the outside world with a bright look. He had already adjusted his condition to the best.
He jumped up from the stone where he was sitting cross-legged, walked around the core of the Dragon Vein Evil Cave, and looked around.
"Eh!" What surprised Xu Dao was that although the cave in front of him was much bigger and more evil than the one when he came, the environment was no different. It was still an empty, dark underground cave.
.
He explored carefully again, but still didn't see any evil spirit taking shape in the cave.
Gradually, Xu Dao focused his attention on a puddle of water in the cave. He walked over and squatted next to the puddle.
"According to Xiaoying's exploration, this place is connected to an underground river. The water quality is cold and cold, and there is something else going on inside..."
Xu Dao stretched his fingers out of the stagnant water, and found that the water was bitingly cold, and there was an unknown amount of cold air mixed in it.
Fortunately, due to the cold weather, Nan Ke was barely able to enter the water, and his physical body could naturally do the same.
Looking at the dark puddle, Xu Dao calmed down and thought, "This is already the core of the Dragon Vein Evil Cave. The earthworm is not good at water, but he did not find danger in the underground river. Instead, he smelled the smell of spiritual energy...
…”
Without thinking too much, he guessed that through the underground river below, he could find the dragon vein of Sheshan Mountain.
"Wealth can be found in danger. Besides, I have tested it with earthworms. Even if there is danger, I should be able to deal with it."
Gritting his teeth, Xu Dao made a decision in his heart.
However, he did not jump directly into the underground river in panic. He still called out a large group of earthworms from the earthworm flags and ordered them to take the lead and serve as sentinels.
After ten thousand earthworms entered the water, the water surface shook, and Xu Dao jumped directly into the puddle.
It was cold and cold, as if it would freeze his thoughts. What was strange was that his heart was hot and restless, cold on the outside and hot on the inside, giving people great suffering.
What shocked Xu Dao even more was that after he personally entered the water, he actually felt the existence of some evil spirits in the water.
This surprised and delighted him: "No wonder many earthworms stop here. There are evil spirits coming out. If you swim here, you will find your spiritual veins."
He quickly gathered his strength and swam forward along the underground river.
There was one thing that made him not sure whether he should be lucky or regretful. Because the evil spirit was melted into the water, its quantity was thin and rare, although it would not cause serious obstacles to him.
But in this way, if he wants to collect evil spirits here later, it will be difficult to do so.
There were many distracting thoughts in his heart, Xu Dao suppressed his mind, just hoping to swim through this place quickly and find a place full of spiritual energy.
Finally, a cricket came back from the front and brought a lot of good news. But at the same time, there was also bad news.
Xu Dao got the warning from the fox fly, and the golden light on his body suddenly dimmed, and he pinched the breath-containing jade hook he wore around his waist to gather the energy in his body.
The earthworms that were released early in the morning were not taken back, but were still scattered around to serve as eyes and ears.
Soon, the underground river was no longer pitch black, and there was a faint light coming from the front. At the same time, the water was still bitterly cold, but there was spiritual energy mixed in it.
"Spiritual pulse!" Xu Dao in the water immediately noticed this, his mind suddenly became strong, and he swam forward even harder.
Not long after, he swam out of the underground river and came to a wide body of water. The nearby spiritual energy was full, and the concentration was similar to that in the Sheshan Ghost Market.
And every time you swim forward a few dozen or nearly a hundred feet, the aura in the water will become even richer.
Xu Dao stopped. He took out a water bag filled with air from the cricket flag and began to breathe. While breathing, he looked around.
Suddenly, Xu Dao's eyes froze and he swam forward to the right.
I saw a large broken stone tablet inserted at the bottom of the water. There were writings the size of a human body on it. It was vaguely identifiable: "Palace", "Forbidden" and "Zhi".
Xu Dao stepped in front of the stone monument and found that the bottom of the river was on a slope, and it continued to sink toward the back of the stone monument.
When he followed his eyes, he saw light swaying on the top of the water in the distance, and falling far into the dark bottom of the lake in front of him.
A huge palace shaped like black iron suddenly appeared in Xu Dao's eyes, and its figure disappeared, reflecting the cold light of metal in the water.
