After receiving the wood core of the Iron Essence, the Burning Crystal and the Thousands of Strands of Trees, Ye Li took over the fire from Ou Qianxi's hands, and imported his own aura to keep the flames on the Little Earth Fire Refining Heavenly Furnace burning.

Then he took a deep breath and threw the iron essence in his hand into the flames.

Iron essence is the hardest of the three materials and the least easy to melt, so Ye Li has to heat it first.

The temperature of the blazing white flame was extremely high, and after only a few moments, the solid iron essence began to melt.

Seeing that the time was almost up, Ye Li threw the burning crystal in his hand again.

When the Burning Crystal encounters the flames, it melts quickly like ice cubes under the sun, turning into a fiery red liquid suspended in the flames.

The molten iron refined by iron, together with the crimson liquid formed by burning crystals, was directly suspended above the small earth fire refining heavenly furnace, as if there was an invisible force that held them all up.

The blazing white flames continued to scorch the two materials, emitting bursts of green smoke, which were all impurities mixed in the materials, and at this time, under the calcination of the fire, they were quickly separated.

Immediately after, Ye Li poured the power of his divine consciousness into the two liquids in front of him, and began to guide them to merge with each other.

Ye Li's divine consciousness power condensed into a vortex in the air, and began to drive the two masses of liquid to rotate and mix.

After almost a stick of incense, the two masses of liquid completely fused together, and they were no longer separated from each other.

Immediately after, Ye Li controlled the output of the spirit element in his hand, and lowered the flame temperature on the small earth fire refining furnace to a relatively low state.

The two masses of liquid fused together began to gradually cool, from the initial liquid state to a semi-coagulated state.

In the induction of Ye Li's divine sense, in this semi-condensed mixture, various subtle imprints began to appear as the temperature decreased.

The marks appeared to be very disorganized, as the fusion of the two different substances caused them to become more and more chaotic.

But fortunately, Ye Li's study this month is very serious, and he has also studied the appearance of the core runes in the Iron Essence and Burning Crystal before, so it can't be said that he is clueless to look for in various imprints at this time.

It took him about a stick of incense to discover two core runes that were almost intertwined with two materials.

According to the method that Ou Qianye had taught him before, Ye Li began to control the fusion of these two core runes with each other.

It was as if there was a rule force driving the combination of these two runes, and what Ye Li wanted to do was to control them not to accidentally explode when they fused.

If the two runes exploded when they fused, it would also mark the complete destruction of the material, and even if they were melted again, they would lose their original utility.

While controlling the temperature change, he guided the two runes to gradually merge into a new rune, and it was not until this step was completed that Ye Li breathed a sigh of relief, the production of the rune flag had passed the most dangerous stage.

Immediately after, Ye Li began to inject the power of Spirit Yuan and Divine Consciousness into this group of nascent runes, and then he felt that he was completely in control of this mass of materials, and all the imprints around him could slowly change with his mind.

The imprints around him comb themselves from a disorderly mess, and then split in a special way, turning the entire mass of material into a mixture of three smaller masses.

Controlling the three mixtures separately, Ye Li was multi-purpose, and the imprints inside the control began to completely assimilate into a trajectories according to his thoughts.

These imprints are not set randomly, but are arranged according to the properties of the material itself.

As long as it changes within a certain range, there will be no problem, but once the changes in these marks exceed this range, the material that is out of range will be broken and shattered from the original material.

In the previous month, Ye Li had memorized these things that needed attention, and now with the guidance of memory, he successfully arranged the trajectories in the three groups of materials.

At this moment, he felt that the three mixed groups that had been split apart seemed to have become a whole, and the aura could be transmitted back and forth in the three different mixtures to form a complete circuit.

Feeling such a situation, Ye Li finally knew that the flagpole he had forged was basically completed.

The next thing he had to do was to control the mixture of three balls to slowly change shape, gradually changing into the shape of a flagpole.

At this point, this casting has basically come to an end.

Ye Li lowered the temperature of the flame again, allowing the flagpole to gradually solidify completely, and finally threw it into the wooden core of the inextricable tree.

This core was completely different from ordinary wood, and instead of burning directly in the flames, it slowly melted down, turning into a very viscous liquid.

Ye Li controlled the liquid to split into three, then pulled out the filaments and began to wrap and weave with each other, and finally formed three small flags at the top of the three flagpoles.

At the moment when the talisman flag was fully formed, Ye Li stopped the input of the spirit element, and the flame of the small earth fire refining heavenly furnace was extinguished in an instant.

After losing the calcination of the flame, the rune flag quickly cooled down, and the originally fiery flagpole slowly turned crimson, which was the color of the previous burning crystal.

"It's successful, Master, the casting of the rune flag is complete!"

Ye Li used Lingyuan to hold three flags and put them on the table, and then shouted happily, this was the first time he used the method of casting a talisman flag to cast a talisman flag, which made him can't help but feel a burst of excitement in his heart.

"Okay, yes, I didn't expect you to succeed in refining the rune banner after only one attempt.

But you have to act fast, now the production of this set of rune flags has not been completed, if you don't take advantage of the flag has not completely cooled down, the spell will be engraved on the flag, after a while the flag is cold, the spell will not be depicted, this set of rune flags will also be scrapped. ”

Ou Qianye touched his beard and smiled to remind Ye Li.

In fact, he was also very satisfied in his own heart, Ye Li had just been refining in his eyes, and in his eyes, his newly recruited disciple was really talented, even if it was the first time to refine, he also looked at ease and relaxed.

After Ou Qianxie's reminder, Ye Li suddenly remembered that the talisman must be drawn before he was cool, otherwise once it was cold, he would no longer be able to draw the talisman.

Not daring to delay any longer, Ye Li hurriedly took the talisman pen and talisman ink from the table next to him, and then flattened the flags on the three flagpoles, preparing to draw a set of nine-character three-text runes.
