Although there are four altars in the space for refining Dao artifacts in the "Heaven and Earth Furnace", only one is currently open, and only one can be refined.

After turning the immortal furnace into a Taoist weapon, Dianhua happened to have four immortal weapons left, the immortal sword, the immortal robe, the immortal disc, and the immortal mirror.

"The first one, which one should you choose?"

The Immortal Disc and the Immortal Mirror had already begun to evolve into Dao weapons, and if they chose any of them, they would definitely be able to speed up their evolution.

Intellectually speaking, you should choose one from among them, and at the fastest speed, the refining will be successful, and then the refining of the next Dao weapon will be started.

But......

There are some things that can't be counted like this!

After hesitating for a moment, in the end, Dianhua chose the fairy sword.

Why choose Sword and Fairy?

Since the fairy sword came out, he has been working hard and complaining, working hard, and helping Dian Hua a lot.

Moreover, in the acquisition of the dotted fruit, the fairy sword played a key role.

Whether it is a red dotted fruit, a yellow dotted fruit or a cyan dotted fruit, most of them are the credit of the fairy sword.

Especially the cyan dotted fruit, the place where the evil is drained in the river basin is purified by the fairy sword, and it can be said that eighty percent of the progress of the cyan dotted fruit is completed by the fairy sword.

Dianhua took the overall situation, and did not use the cyan dotted fruit to turn the fairy sword, but lit the immortal furnace, which is already a bit unspeakable, if the first immortal weapon of the Dao weapon is refined with the "Heaven and Earth Furnace", or does not choose the fairy sword, then it is really unreasonable!

After making a decision, Dian Hua took out the fairy sword and sent it into the "Dao Weapon Evolution" space of the "Heaven and Earth Furnace".

Under the gaze of the divine sense, Dian Hua saw that in the "Dao Weapon Evolution" space with a diameter of only one hundred meters, the fairy sword suddenly appeared at the edge of the space.

Then, as if something was attracting it, it naturally fell to the only altar that had no enchantment, and finally landed gently on the altar.

After falling on it, the cyan clouds around it suddenly surged, and began to rush towards the altar where the fairy sword was placed, and then poured into the altar, submerged into the fairy sword, and disappeared.

"It turns out that the cyan clouds and mist in the 'Dao Instrument Evolution' space are the manifestation of the Dao power of the 'Heaven and Earth Furnace'. At this time, Dian Hua suddenly realized.

"I didn't expect that the 'Heaven and Earth Furnace' had just become a Dao weapon, and it had stored so much Dao power?!"

Dian Hua deduced a little, and figured out the cause and effect.

Before the birth of the "Forge of Heaven and Earth", the activity of refining appeared in this world a long time ago.

Especially the human race, whether it is the refining of metal tools, or cooking and cooking, etc., it is actually the embodiment of the way of refining.

With the continuous improvement of human civilization, these refining activities will become more frequent and larger.

The Terrans of this world may not be too obvious...... It is entirely analogous to the 5,000-year history of the earth, especially after the Industrial Revolution...... After breaking the limitations of resources and labor, human refining activities increased exponentially.

It's just that there was no corresponding Dao weapon or monk before, and there was no Dao weapon or monk to absorb these Dao powers, so they could only permeate the air, and over time, slowly dissolve between heaven and earth.

And now, with the "Heaven and Earth Melting Pot" that integrates the way of refining, the "Refining Dao Power" naturally has a home, no longer like a homeless child, but like a hundred birds returning to the forest and a hundred rivers returning to the sea, pouring into the "Heaven and Earth Melting Pot".

"This can be regarded as an invisible benefit of the first refining results!"

Based on this reasoning, if the other Dao weapons are refined, they must also be like the "Heaven and Earth Melting Pot", just after they are formed, they will absorb these masterless Dao powers that have accumulated for countless years from between heaven and earth, and immediately have a certain amount of Dao power reserves.

......

Under the gaze of Dianhua's divine sense, with the consumption of cyan clouds and mist, the shape of the fairy sword did not change, but the material slowly began to change, turning into a translucent sword weapon that was neither gold, nor wood, nor stone, nor water.

"Sure enough, the 'Heaven and Earth Melting Pot' is not an exception, after the immortal sword is transformed into a Dao weapon, it will also produce huge changes. ”

The immortal furnace is a change in appearance, while the fairy sword is a change in material.

Although the direction of change is different, they all lead to the same goal.

After the change of the fairy sword, the cyan cloud did not stop pouring in, it was still pouring in, and a colorful bubble slowly formed in the sky above the altar.

The bubble grew from the size of a fingernail to a fingernail, until the cyan cloud was exhausted, and a bubble with a diameter of 100 meters was formed.

Countless sword shadows could be faintly seen in the bubbles, and these sword shadows were combined to vaguely resemble a suspended mountain.

"A hundred meters in diameter, I remember that the diameter of the Heaven and Earth Furnace Evolution Space is only a hundred meters, right?"

Dian Hua looked around, only to find that unconsciously, the diameter of the evolutionary space had expanded to two hundred meters in diameter, which was nearly twice as large as the original.

"Could it be that refining Dao tools is also a growth for the Heaven and Earth Furnace?"

After Dianhua communicated with the spirit of the furnace of heaven and earth, he received positive feedback.

"Also, the Heaven and Earth Furnace is originally a Dao weapon that integrates the Dao of refining, and its growth naturally needs to grow in refining, and refining the Dao Weapon can undoubtedly make it grow the most significantly. ”

Dian Hua's consciousness communicated with the fairy sword, knowing that the bubbles on it were evolved, and after the fairy sword was transformed into a dao weapon, it would look like a dao space.

"This mountain with sword shadows is somewhat familiar...... Oh, by the way, it looks like the 'Sword Shrine' in the sword fairy genre movie I've seen before!"

Dian Hua had a guess in his heart: "I remember that when I lit the fairy sword, it was an entertainment work taken from the fairy sword genre, is it ......?"

Could it be that in the end, when it was transformed into a Dao weapon, it was really refined and the sword mound group came out?

Dian Hua once again communicated with the instrument spirit of the "Heaven and Earth Melting Pot" and knew the conditions for the immortal sword to evolve the Dao weapon.

"With the help of the 'Heaven and Earth Melting Furnace', use the 'Son and Mother Refining Method' to refine the sub-weapon magic sword, and then let others contract this sword as a natal magic weapon, and spend a lifetime specializing in swordsmanship, and swordsmanship at least has the realm of sword intent, or even higher swordsmanship.

"And pinned this swordsmanship on this sword, and finally after its death, the sub-weapon magic sword flew into the 'Dao Space' in the 'Heaven and Earth Furnace', absorbing the power of the sword path inside, and constantly perfecting itself.

"When the number of sub-weapon magic weapons that have returned in this way reaches a certain number, the power of the sword dao absorbed reaches a certain level, and the Dao domain space turns from virtual to real, the Dao weapon will be successfully refined. ”

After understanding, Dian Hua deduced a little and found that the most suitable way was to reproduce the model of the Shushan Sword School in the entertainment works to create a special sword cultivation line.

"It's really a cycle of cause and effect!"

With the reason for the original literary and entertainment works in the genre of sword immortals, there is a reason to create a sword cultivation in reality at this time.

"Refining the false becomes true, this really corresponds to the true meaning of cultivating the truth!"
