Zoroastrianism, one of the three major sects of Shenzhou, has been inherited for thousands of years, sitting on the largest ore vein in Shenzhou, with rich alchemy technology and experience accumulation, for thousands of years, Zoroastrianism has always been the strongest sect of alchemy in Shenzhou, not only with huge annual output, but also extremely high quality. Any core disciple of the Zoroastrian Sect, while cultivating martial arts, must also learn alchemy, especially the four elders, who are the best among them, so the four elders know very well that it is very difficult to learn alchemy.

When they first came into contact with alchemy, the four elders thought that alchemy was nothing great, and it felt no different from striking iron, and with the deepening of learning, they gradually realized that alchemy was easy to get started, but if you want to master it, it is difficult to climb to the sky. The four elders were extremely talented and had studied for a hundred years, but they could still only refine magic weapons.

Now the holy woman told them that Ye Fan, who was young, was a top refiner in Shenzhou, which made the four elders feel incredible, and their hearts were full of shock, but also great doubts. Because when they were like Ye Fan's age, they could refine three-grade magic weapons at most, and the success rate was very low.

Seeing the shocked and incredulous faces of the four patriarchs, the holy maiden smiled slightly and said, "Four patriarchs, I know that you may not believe what I say, as for whether what I said is true, can't you just let Elder Ye refine it on the spot?"

Elder Jin nodded and said, "What the Holy Maiden said is right, now the time is pressing, let's go directly to the mine, where a large amount of ore has been accumulated, not only in large quantities, but also in many types, and the grade is very high, which is the accumulation of Zoroastrianism for a hundred years." ”

Hearing this, Ye Fan suddenly came to his senses, it is impossible to improve the strength of the various sects in a short period of time, but if there are enough weapons and armor, it can also improve the attack and defense power of the martial artists. If the Zoroastrian mine has enough ore, with Ye Fan's refining speed and level, he can refine enough magic weapons and spiritual weapons.

Thinking of this, Ye Fan said: "Time is indeed very urgent, we have to race against time, now let's go to the mine, I can't wait." As he spoke, Ye Fan's eyes flashed with a shining glow, everything Ye Fan did now was to defeat the Yin Sha Gate, and then open the forbidden land and get the mysterious fruit on the ancient tree.

On the way to the mine, the Holy Maiden arranged for someone to go to the Sword Sect to inform the Sword Sect about the Yin Sha Gate, so that the Sword Sect could take precautions in advance, and at the same time, she also arranged a messenger to ask the Shenxiao Gate to strengthen its precautions in the name of Zoroastrianism.

Zoroastrian's mine is located in the middle of the Yan Mountain, there is a huge underground karst cave, after a simple artificial transformation, it becomes a huge mine, the mine is divided into two parts, the core is the treasure house, and the outside is the general library, which stores high-grade and ordinary ores respectively. Standing in front of the cave, Ye Fan couldn't help but gasp, the Zoroastrianism, which has been inherited for thousands of years, is really profound, and it actually has such a huge mine underground.

With such a huge scale, it is comparable to the Sword Sect's medicine garden.

The saint introduced: "For many years, the sect leader has been busy fighting for power within the sect and has not cared much about the mine, otherwise, the mine would have been tossed into a miasma. After speaking, the holy woman breathed a heavy sigh of relief, the mine warehouse stored the ore accumulated by the Zoroastrian religion for a hundred years, which was a huge wealth, fortunately preserved.

Elder Jin nodded, and said to the Holy Maiden: "The mine is the core of Zoroastrianism, as long as the mine is still there, even if Zoroastrianism is disabled, there is still a possibility of re-emerging, Elder Ye, let's go to Puku to take a look, and you will choose the ore you need." With that, Elder Jin walked to the huge iron door and twisted the iron lock.

Ye Fan really had some expectations in his heart.

After waiting for half a pillar of incense, Elder Jin was still twisting the huge circular iron lock, and the gate did not move at all, Ye Fan suddenly frowned, and secretly said in his heart, Could it be that Elder Jin forgot the password to open the iron lock? Although this idea is a bit ridiculous, judging from the current situation, it is very likely that he has forgotten the password. Ye Fan secretly said in his heart, this is embarrassing.

The Holy Maiden and the other three elders were indeed embarrassed, smiled at Ye Fan, and then hurriedly walked to Elder Jin's side and asked in a low voice, "Elder Jin, what's wrong? Isn't the original password usable?"

Elder Jin sweated anxiously, and said with an embarrassed face: "The password can't be used, it must be that the sect leader has changed the password, worried that we will steal the ore in the mine, now that the sect leader is dead, we can't get the password, it is too difficult to think of opening the gate, it will take at least half a month." After speaking, Elder Jin sighed helplessly, he had known that he would have kept the sect leader's dog life first.

Now, though, it's too late to regret it.

The saint said in a low voice: "This gate is cast of stainless steel, it is cast by the first generation of saints, it is extremely hard, even if you have a spiritual weapon, you can't break it, if it takes half a month to unlock the code, maybe the Yin Evil Gate has already begun to act." After speaking, the saint sighed helplessly, everything was going well at first, but the last thing that shouldn't have gone wrong was something wrong.

Ye Fan walked up to the saint and said, "Can't you open it?"

The holy woman nodded and said, "The sect leader has changed the password, the previous password is invalid, although we can unlock the password, but it will take half a month." ”

Ye Fan said, "I'll take a look." After speaking, Ye Fan pressed his hand on the iron lock, and then activated his divine sense to carefully inspect the gate, and in a few seconds, Ye Fan explored the internal structure of the entire gate clearly, and couldn't help but gasp, it is worthy of being a sect with the highest alchemy skills, and it can actually refine such a delicate iron gate.

Not only is the volume huge, but the internal structure is extremely complex, which is the most complex mechanism lock Ye Fan has encountered, and there is no one.

"This gate itself is a first-grade spiritual weapon, there is a complex mechanism lock device inside, every small part is a nine-grade magic weapon, and the internal structure of this gate, in addition to the mechanism technique, there are traces of the formation, if you don't use the password and forcibly destroy it, it is almost impossible to complete. Ye Fan said in a deep voice.

"How do you know?" The Holy Maiden and the four elders looked at Ye Fan in surprise, they were about to tell Ye Fan, but Ye Fan knew it himself, and he knew it in detail. The point is, how did Ye Fan know? Just by looking at his appearance, he could see it? How could this be?

The Holy Maiden had seen Ye Fan with too many magical methods, and she had some immunity, so she reacted first and said, "Elder Ye, do you have a way to open the door?"

Hearing this, the four elders looked at Ye Fan expectantly, hoping that Ye Fan could create a miracle, although they knew that the possibility of creating a miracle was too small, but they could only hope to create a miracle, otherwise, it would be delayed for half a month, and it might not be able to be solved.

Ye Fan said with a solemn face: "Your mine is too complicated, it is cast by a master, if you want to unlock it, it is too difficult, I can only say try it as much as possible." After speaking, Ye Fan opened his divine sense again, and then twisted the disc iron lock slightly, the saint and the others did not dare to disturb Ye Fan, and stood quietly in place, not even daring to come out.

The saint and the others thought that Ye Fan wanted to listen to the sound of the gears and then judge the way to untie it, so they deliberately suppressed the rhythm and sound of breathing.

The huge cave is filled with the slight sound of gears spinning, squeaking......

Under the shroud of divine consciousness, the structure of the trap lock formed a three-dimensional structure diagram in Ye Fan's sea of consciousness, and then simulated operation, only a few seconds of operation, Ye Fan suddenly spoke: "The heavenly stems and the earthly branches, the twenty-eight constellations, all-encompassing, there are countless changes, it is worthy of the power of thousands of years ago, and it can actually cast such a mysterious gate." ”

The saint nodded and said softly: "The gate has existed for thousands of years, and it was cast by the first generation of saints herself. ”

"It's very difficult, and I'm not too sure. Ye Fan said in a deep voice, and then continued to start the calculation, more powerful than the supercomputer, Zhihai, under the manipulation of Ye Fan, began to practice crazy, the heavenly stems and the earthly branches, the twenty-eight constellations, constantly rotating and combining in the sea of knowledge. Gradually, Ye Fan felt a little overwhelmed, too much energy.

The Holy Maiden and the Four Great Elders stood in place, looking at Ye Fan with a puzzled expression, they found that Ye Fan was just twisting the disc iron lock and had no other movements, but even so, beads of sweat appeared on Ye Fan's face, and his expression was heavy, as if he was under tremendous pressure. Although the saint and the others were in a hurry, they knew that they couldn't help, so they could only do it in a hurry.

After half a pillar of incense, Ye Fan suddenly breathed a sigh of relief, released the iron lock of the disc, sat down on the ground, gasped for a few breaths, and after taking a spirit pill, he began to close his eyes and recuperate.

The Holy Maiden and the four elders were even more puzzled, they didn't see Ye Fan make any moves just now, but now it looks as if Ye Fan had experienced a fierce battle just now.

"Holy Maiden, Elder Ye, what's wrong?" Elder Jin asked in a low voice.

"I don't know, wait and see, we don't have any other good way anyway. The holy woman whispered, and then looked at Ye Fan.

It didn't take long for Ye Fan to open his eyes, a glimmer of light flashed in the corners of his eyes, and then under the puzzled eyes of the saint and others, Ye Fan slowly stood up, grabbed the disc iron lock again, and twisted it gently.

The Holy Maiden really couldn't help it, and said, "Elder Ye, if you can't do it, don't force it. ”

Ye Fan smiled slightly and said, "I've already untied it." After speaking, Ye Fan quickly twisted twice, and then pushed down the disc iron cable, and the door of the mine made a slight friction sound, and then slowly opened.

"My God, it's opened!" exclaimed the saint.
