Spring passed and autumn came, and more than two years had unknowingly passed. After collecting all the materials, Zhang Ling entered the earth fire room to begin refining his destined magic treasure.
The Diyuan True Spirit Art that he was currently practicing contained several methods for refining destined magic treasures. It even recorded several techniques for refining magic treasures using some special materials, and even had extremely harsh requirements for flames.
However, Zhang Ling naturally didn't need to consider these. He only needed to set up the most core formation and refine the treasure step by step according to the simplest destined magic treasure refining method.
After all, most destined magic treasures are custom-made, and even the choice of materials for the same type of magic treasure varies greatly. As long as they are the same type of magic treasure, the core refining steps will basically not change.
After careful consideration, Zhang Ling chose a method called the Three Yuan Treasure Refining Method and prepared to start refining the treasure.
This method also emphasized setting up a small formation to assist in the refining of the destined magic treasure. The details were recorded in detail, and Zhang Ling spent more than ten days refining the matching formation plate and formation flags after entering the earth fire room.
For this reason, he also expanded the entire earth fire room several times to arrange this formation.
He was able to refine the formation equipment so quickly thanks to the relevant classics left by Long Lao, the formation master.
Zhang Ling had also spent several years studying the art of formations. However, the effect was not great, as this path was the most mentally exhausting. He could only understand some simple formations, and it was difficult for him to understand complex formations with more than three formation eyes.
Fortunately, the Three Yuan Treasure Refining Method was very simple to set up. He only needed to follow the formation diagrams recorded in the Three Yuan Treasure Refining Method step by step.
Afterwards, he set up a set of spirit concealing formations outside the entire earth fire room. This formation had only one purpose, which was to shield the fluctuations of spiritual power.
He didn't want to be spied on or even killed and robbed during the process of refining his destined magic treasure.
After these auxiliary matters were handled, Zhang Ling first sat cross-legged in the quiet room for several days to calm his mind and reach his best state before he began refining the treasure.
First, he took out a dozen jade boxes of different sizes, some containing golden ores, and some containing special liquids that shimmered with spiritual light. He first used the furnace to refine these auxiliary materials one by one.
This step took more than a month. Then, Zhang Ling cautiously took out the foot-sized Two-Yin Calabash and began to process it.
With the previous experience of processing those dozen gourds, the speed of processing this gourd was not slow, but it also took him a full half a month.
When he took out the gourd seeds from the Two-Yin Calabash, Zhang Ling's expression first froze and then he was overjoyed.
He found more than a dozen black gourd seeds from the gourd. These black seeds were exactly the same as the gourd vines he had planted at the beginning.
Although he couldn't go out to test it now because he was in the process of refining the treasure, he guessed that these black gourd seeds were the real seeds of the Two-Yin Calabash. He could also sense some vitality of plants and trees on the black gourd seeds, which was different from the green gourd seeds.
With this discovery, it meant that even if he failed this time, he could still grow the Two-Yin Calabash again.
Zhang Ling cautiously took out a jade bottle, poured all these black gourd seeds into it, and attached a few spiritual talismans before putting it into his storage bag.
Then, after calming his mind, he expressionlessly processed the Two-Yin Calabash.
The inside of this gourd was also different from other gourds. When his divine sense penetrated into it, he could sense that there was actually a space of considerable size inside.
Upon closer inspection, the space was as large as several miles, and a layer of mist floated in it. These mists were constantly tumbling, turning blue for a while and white for a while.
Could this be the so-called Azure and White Qi? Zhang Ling couldn't help but exclaim in his heart.
There was no special feeling when his divine sense wandered in these mists, just like ordinary mist.
The fact that there was a space in the gourd reminded Zhang Ling of the big bronze cauldron in which he and Ding Ruozhao were trapped before. There was also a considerable space in that yellow cauldron.
This kind of treasure with an internal space is extremely rare, and Zhang Ling couldn't calm down for a while. It took a long time before he recovered and returned to his usual state of mind.
Whether it's alchemy or weapon refining, the most taboo thing is to be impetuous. Only with a normal state of mind can you refine the best treasure.
Speaking of which, this kind of naturally formed artifact is the simplest to refine compared to other materials.
Zhang Ling waved his hand, and the gourd was fixed in mid-air. Immediately, he opened his mouth and spat out a golden core with a yellow halo.
This was the golden core he had cultivated through hard work. Zhang Ling's hands flew quickly, condensing a series of magic formulas and hitting them on the golden core. Suddenly, the yellow light on the golden core brightened and a ball of dark yellow pill fire rose.
Then, the golden core began to move quickly around the gourd, releasing a large amount of yellow pill fire. In an instant, the entire gourd was dyed blue and yellow.
The Two-Yin Calabash also kept shaking, emitting a layer of spiritual light, turning blue for a while and then turning white again.
This was the gourd itself resisting the refining of the pill fire.
Items like this that are used to condense magic treasures are not ordinary things in the first place, and refining them is a very long process.
Pill fire is transformed from the essence, qi, and spirit of a Golden Core cultivator. Using it not only consumes the spirit but also consumes a great deal of spiritual power.
Zhang Ling sat cross-legged without moving, constantly spewing pill fire to refine the Two-Yin Calabash.
At this moment, there were also seven or eight white jade bottles placed at his feet, filled with pills that quickly restored spiritual power.
At the same time, he was also holding a middle-grade earth attribute spirit stone in his hand. These were all prepared for this treasure refining.
The Two-Yin Calabash was constantly refined like this for seven days, and the gourd began to change. The spiritual power on the surface had been almost worn away by the pill fire, and a crackling sound came out.
The sound sounded loud, as if the entire gourd was burning. However, the gourd in the pill fire was only rotating slowly. The only difference was that every once in a while, a wisp of gray smoke floated from the gourd, turning into black powder and falling to the ground. These were the impurities on the gourd.
This scene continued for more than half a month. At a certain moment, the magic formula in Zhang Ling's hand suddenly changed. His expression became even more solemn as he spat out several groups of essence, which turned into wisps of yellow spiritual power and submerged into the gourd.
The entire gourd instantly emitted a dazzling blue light, which became brighter and brighter, and the entire earth fire room was dyed blue.
This scene lasted for more than an hour, and the blue light gradually weakened and all concentrated on the gourd.
